Are you worried by the rising crime rate? If you are, you probably know that your house and possessions are increasingly in danger of suffering from great rise in the cases of burglary(夜盗;抢劫) and attack.
Figures show an ever-increasing crime rate, but it is only too easy to imagine "It will never happen to me"．Unfortunately, statistics show that it really can happen to you and, if you live in a large city, you run twice the risk of being a victim.
Fortunately, there is something definite which you can do．Protect Alarms can help to protect your house with a burglar alarm system which is effective, simple to operate and easily affordable.
You must remember that owning a burglar alarm is no indication(暗示) that your house is packed with valuable possessions．It quite simply indicates to unwelcome visitors that yours is one house they will not break into easily, so they carry on to an unprotected house where their job is made a lot easier.

Almost all theme park accidents can be prevented．Here, based on coverage of theme park safety, are some tips to help you and your family stay safe on your next visit.
If you are visiting with a child, take a moment to explain the ride to them, and tell them what they should do．They are depending upon you to keep them safe．Set a good example for them by following the rules of the park, and make sure that they know you expect them to follow those rules, too.
Tell them to stay seated, to hold the grab bar or put their hands in the laps, and not to stick their knees and feet outside a ride vehicle．Make them look to you for the okay to get on or off a ride, too．And never put a crying child on a ride．If your child starts to cry, let others pass you in line until your child is calmed．Or, gently exit the queue and find something more relaxing to do．
Young kids can’t keep an adult’s pace in a theme park．Let them take plenty of breaks.
“Kids get tired,” said TPI reader Matt Johnson, a father of four．“Tired kids make parents even more tired．And tired kids and parents may get hurt — physically and emotionally.” He advises that parents plan a mid-day break, perhaps a swim back at the hotel, to avoid mid-day heat and crowds．“You will see cranky families having a miserable time while you are refreshed and having a great evening.”The second paragraph tells readers that ________.

A famous foreign company that invested in China wanted to employ a reception secretary for its public relation department.
A beautiful girl with a master degree in electric engineering became a winning candidate(候选人) through the difficult process of employment. At its last stage she faced an oral test together with another girl who was her equal not only in good looks but also in education standard. The girl we talk about was confident in herself and successful in the oral test. It seemed that she would get the chance. The examiner told her on behalf of the company that she could come to office of company next Monday as a new employee. At last he asked her, “Have you anything else to say? Shocked by the unexpected question, the beautiful girl was quite at a loss, saying with hesitation(犹豫不决),”“I have to talk with my parents before I give an answer.”Surprised, the examiner said calmly,“In that case, let’s wait till you are ready.”
The next day the girl came to tell that her parents agreed to her beginning work next Monday. But the examiner said regretfully,“Sorry, the job position is filled by another suitable candidate. You had better have a try in another place.”The beautiful girl was surprised. She asked for an explanation and was told,“What is needed here is a person who knows her own mind.”
That was how a good opportunity slipped away right under the nose of a beautiful girl.What did the examiner value most?

Move Earth — it’s no science fiction
LONDON — Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets（彗星）in the direction of Earth, and its orbit will be changed. Our world will then be sent spinning into a safer, colder part of the solar system.
This idea for improving our climate comes from a group of US National Aeronautics and Space Administration（NASA） engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—effectively doubling its working life.
The plan put forward by Dr Laughlin, and his colleagues Don Korycansky and Fred Adams ,needs carefully directing a comet or asteroid so that it passes close by our planet and sends some of its gravitational energy to Earth.
“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the Sun,” Laughlin said.
Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated. In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere（生物圈）— by cooking us.
That’s why the group decided to try to save Earth.
The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation（误算）in orbit could fire it straight at Earth—with deadly consequences.
There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position it is “most likely the Moon would be stripped away from Earth,” it states. This would greatly change our planet’s climate.What makes the scientists plan to move Earth?
| A．A few comets are moving to the direction of Earth. |
| B．Earth’s working life is coming to an end soon. |
| C．Earth will become too hot for mankind to keep alive. |
| D．The moon is moving farther and farther away from Earth. |
If the plan is successful, Earth will have a working life of ______years.
| A．12 billion | B．6 billion | C．18 billion | D．24 billion |
What serious problems might the plan cause according to the passage?
| A．The comet might hit Earth and man might lose the moon. |
| B．Earth might be moved too far away and man might be frozen to death. |
| C．The comet might hit Jupiter or Saturn and never return to Earth. |
| D．Earth’s working life might be greatly shortened. |
What does the underlined word “compromise” mean?
| A．provide | B．benefit | C．share | D．endanger |
Which of the following best shows how the plan would work?
Schedules (timetables), as the 21st century people know, simply did not exist in the 17th and 18th c
enturies. We are upset if a plane arrives an hour late. Our ancestors weren’t upset if an April ship didn’t show up until June. They began to worry in July and were often happy when it showed up in August. When a long-distance ship finally did get to the port, the whole city became busy and excited. Businessmen hurried down to check the goods they had ordered. The ship would probably stay in port for at least three days, often a week, to take on businessmen, give the sailors a rest, find out about the latest news, weather conditions, and so on.
Travel time could only be approximate (近似的). One never knew when the winds would be good. So even though “average(平均的) sailing time” was given, time could change considerably, shortening the voyage (travel by sea) by up to 25% or putting it off by up to 500% or more! The average run from England to Boston was about a month and a half, but there were also voyages of three months. One voyage in 1640 lasted six months!
Travel time is not the same in both directions, due to the winds and currents. This is especially true in the Caribbean, where winds are from the southeast the entire
year. Ships sailing west across the Atlantic spend longer than ships sailing east, and the contrary (opposite) winds can prevent a ship from actually making it to the harbor even if it gets close. One ship was held off the North Carolina coast for 17 days before being able to land! What can we learn from the first paragraph?
| A．No sailor was allowed to have fun when the ship reached land. |
| B．People in ancient times didn’t care about other people’s safety. |
| C．The ship would leave for a voyage when all of the preparations were made. |
| D．A long-distance ship would create a lot of excitement in the place where it landed. |
According to the passage, travel time can’t be fixed due to _____.
| A．the people at the port | B．average sailing time |
| C．the changeable climate | D．the businessmen and the sailors |
The underlined word “currents” in the third paragraph means ______.
| A．the movement of water | B．the movement of winds |
| C．direction of the traveling ship | D．travel time of ships |
What is the difference between a modern voyage timetable and the one from the 17th or 18th century?
| A．There were no exact timetables for traveling both in ancient and modern times. |
| B．Travel time was the same in both directions in ancient times while the modern one was not. |
| C．The modern voyage timetable is more exact than the ancient one. |
| D．The modern voyage timetable is only approximate while the ancient one was not. |
Why did the ships sailing west spend longer than ships sailing east in Caribbean?
| A．Because of the southeast winds the entire year. |
| B．Because sailors didn’t know when the winds blew. |
| C．Because travel time was not affected by wind. |
| D．Because sometimes the ship was held off by the wind. |
Why do men die earlier than women? The latest research makes it known that the reason could be that men's hearts go into rapid decline when they reach middle age.
The largest study of the effects of ageing on the heart has found that women's longevity may be linked to the fact that their hearts do not lose their pumping power with age.
"We have found that the power of the male heart falls by 20--25 percent between 18 and 70 years of age,”said the head of the study, David Goldspink of Liverpool John Moores University in the UK.
"Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70，one-third of those cells die and are not replaced in men,”said Goldspink. "This is part of the ageing process."
What surprises scientists is that the female heart sees very little loss of these cells. A
healthy 70-year-old woman's heart could perform almost as well as a 20-year-old one's.
"This gender difference might just explain why women live longer than men,”said Goldspink.
They studied more than 250 healthy men and women between the ages of 18 and 80，focusing on healthy persons to remove the confusing influence of disease.
The team has yet to find why ageing takes a greater loss on the male heart, said Goldspink.
The good news is that men can improve the 
health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age. The underlined word“longevity" in the second paragraph probably refers to ______.
| A．health | B．long life | C．ageing | D．effect |
The text mainly talks about ______.
| A．men's heart cells | B．women's ageing process、 |
| C．the gender difference | D．hearts and long life |
According to the text, the UK scientists have known that
| A．women have more cells than men when they are born |
| B．women can replace the cells that enable the heart to beat |
| C．the female heart loses few of the cells with age |
| D．women never lose their pumping power with age |
If you want to live longer, you should
| A．enable your heart to beat much faster |
| B．find out the reason for ageing |
| C．exercise regularly to keep your heart healthy |
| D．prevent your cells from being lost |
We can know from the passage that
| A．the reason why ageing takes a greater loss on the male heart has been found out |
| B．scientists are on the way to finding out why the male heart loses more of the cells |
| C．the team has done something to prevent the male from suffering the greater loss |
| D．women over 70 could lose more heart cells than those at the age of 20 |
Leaves are nature’s food factories. Plants take water from the ground through their roots. They take a gas called carbon dioxide (CO2) from the air. Plants use sunlight to turn water and CO2 into glucose（葡萄糖）.Glucose is a kind of sugar. Plants use glucose as food for energy to grow. The way plants turn water and CO2 into glucose is called ph
otosynthesis (光合作用).That means “putting together with light .” A chemical called chlorophyll helps make photosynthesis happen. Chlorophyll is green. It gives plants their green colour. As summer ends and autumn comes, the days get shorter and shorter. This is how the trees “know” to begin getting ready for winter.
During winter, there is not enough light or water for photosynthesis .The trees will rest, and live on the food they have stored during the summer. They begin to close their food-making factories. The green Chlorophyll disappears from the leaves. Then, we begin to see yellow and orange colours. A few of these colors stay in the leaves all the time. We just can’t see them in the summer, because they are covered up by the green Chlorophyll.
Red and purple colors we see in leaves are made mostly in the autumn. In some trees, like maples, glucose is stored in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into red. The brown color of trees like oaks is made from wastes left in the leaves.The underlined word “chlorophyll” in the first Para means in Chinese.
A 叶绿素 B 氧气 C 胡萝卜素 D 蛋白质The way is called photosynthesis.
| A．plants get CO2 from the air |
| B．plants take water from the ground |
| C．plants turn water and CO2 into glucose. |
| D．Plants use glucose as food for energy to grow. |
The gas called carbon dioxide is from the
A ground B roots C air D sunlight Which of the following is not true?
| A．when autumn and winter come, the days get shorter and shorter. |
| B．During winter trees rest and live on the food they store during the summer. |
| C．During winter small amounts of yellow and orange colors are kept in the leaves all the time. |
| D．Trees begin to stop making food in summer. |
For more than six million American children, coming home after school means coming home to an empty house. Some deal with the sit
uation by watching TV. Some may hide. But all of them have something in common. They spend part of each day alone. They’re called latchkey children. They’re children who look after themselves while their parents work and their bad condition has become a subject of concern（关心）。
Lynette Long was once the principal（校长）of an elementary school. Said, “We had a school rule against wearing jewelry. A lot of the kids had chains around their 
necks with keys attached（附带）。 I was often telling them to put them inside their shirts. There were so many keys that it never came to my mind what they meant.” Slowly, she learned they were house keys.
She and her husband began talking to the children who had them. They learned of the effect working couples and single parents had 
on their children Fear is the biggest problem faced by children at home alone. One in each three latchkey children the Longs talked to reported being scared（害怕）.Many had nightmares and were worried about their own safety.
The most common way latchkey children deal with their fears is by hiding. It might be in a shower stall, under a bed, in a closet. The second is TV. They’ll often play it high volume.
It’s hard to get statistics（统计数字）on latchkey children, the Longs learned. Most parents are slow to admit they leave their children alone.The main idea about “latchkey” children is that they ______.
| A．tiredness | B．freedom | C．loneliness | D．fear |
The word “nightmare” in the third paragraph probably means______.
| A．night suit | B．night habit |
| C．terrible dream at night | D．staying up at night |
We may draw a conclusion that_______.
Two thieves came to a house to steal something. They dug a hole in the wall of the house. One of them crawled into the house while the other waited outside.
There lived many mice in the house. The woman in the moonlight saw a mouse crawl into the house. “look! In comes one.” She said to the man in the house. Te thief was so frightened that he hurriedly crawled out of the house and said to the one waiting outside, “She found me when I was just in.” But the thief outside didn’t belie

She saw two men selling sweet potatoes and wanted to buy some. She picked out two which looked like mice. At the time the man couldn’t wait of her any longer and he ran back from the fields to hurry her up. The woman showed the sweet potatoes to the man and said, “How they look like the two of last night.” The man said, “ I asked you to fetch a rope.

Some people bring out the best in you in a way that you might never have fully realized on your own. My mom was one of those people.
My father died when I was nine months old, making my mom a single mother at the age of eighteen. While I was growing up, we lived a very hard life. We had little money, but my mom gave me a lot of love. Each night, she sat me on her lap and spoke the words that would change my life, “Kemmons, you are certain to be a great man and you can do anything in life if you work hard enough to get it.”
At fourteen, I was hit by a car and the doctors said I would never walk again. Every day, my mother spoke to me in her gentle, loving voice, telling me that no matter what those doctors said, I could walk again if I wanted to badly enough. She drove that message so deep into my heart that I finally believed her. A year later, I returned to school — walking on my own!
When the Great Depression (大萧条) hit, my mom lost her job. Then I left school to support the both of us. At that moment, I was determined never to be poor again.
Over the years, I experienced various levels of business success. But the real turning point occurred on a vacation I took with my wife and five kids in 1951. I was dissatisfied with the second-class hotels available for families and was angry that they charged an extra $2 for each child. That was too expensive for the average American family. I told my wife that I was going to open a motel (汽车旅馆) for families that would never charge extra for children. There were plenty of doubters at that time.
Not surprisingly, mom was one of my strongest supporters. She worked behind the desk and even designed the room style. As in any business, we experienced a lot of challenges. But with my mother’s words deeply rooted in my soul, I never doubted we would succeed. Fifteen years later, we had the largest hotel system in the world — Holiday Inn. In 1979 my company had 1, 759 inns in more than fifty countries with an income of $ 1 billion a year.
You may not have started out life in the best situation. But if you can find a task in life worth working for and believe in yourself, nothing can stop you.

Early rising is helpful in more than one way. First, it helps us to have good health. We all need fresh air. It makes our health better to take morning exercises. The air is never so fresh as early in the morning. Early rising helps us in our studies. In the morning we learn more quickly and find it easy to learn something by heart.
Early rising makes people able to plan the work for the day. We can’t work well without a good plan. Just as the plan for the year should be made in the spring, the plan for a day should be made in the morning. Early rising gives us enough time to get ready for our work, such as to wash our hands and eat our breakfast. So the popular saying says, “Early to bed and early to rise makes a man healthy, wealthy and wise.”
51. What does “early rising” mean in the passage?
A. waking up B. getting up C. have breakfast D. making a day’s plan
52. Why does the passage advise us to take exercises early in the morning？
A. Because we can save much time. B. Because we are not busy in the morning.
C. Because air in the morning is very fresh. D. Because we don’t need to prepare for breakfast.
53. We can work well with _____.

The porter brings your bags to your room and helpfully explains all you want to know．Then he points to the phone and says：“If there’s anything else you need, just can．”All this time you have been thinking of one thing：“How much should I tip(付小费)him?”To make your next trip a little easier, here’s guide to tipping across some Asian countries.
Bangkok
In general, the more westernized the place is, the more likely you will be expected to leave a tip．Some top-end restaurants will add a 10％ service charge to the bill．If not, waiters will appreciate your tacking on(附加)the 10％ yourself．However, if you’re eating at a lower-end restaurant, a tip is not necessary．If you’re staying at one of Bangkok’s many five-star hotels, expect to tip the porter 20 to 50 baht(泰国货币单位),depending on how many bags you have．Taxis are now metered 
in Bangkok．Local custom is to round up(凑整数)the fare to the nearest five baht．
Hong Kong
Tipping is customary in this money-mad metropolis(大都市)．Most restaurants add a 10％ service charge to the bill, but the extra money often ends up in the pocket of the owner.
If the service is good, add another 10％ to the bill, up to HKMYMl00 in an especially nice restaurant．For HK MYM10 hotel porters should do it at all but the nicest hotels where a new HKMYM20 bill may be more acceptable．When in a taxi, round up to the nearest dollar．
Kuala Lumpur
Tipping in Malaysia is limited to the expensive westernized hotels, which often add a 10％ service charge to your meal or hotel room．If you are at a hotel restaurant, expect a 10％ service charge．
But at local restaurants, there’s no need to add a tip. At five-star hotels, one or two ringgit(马来西亚货币单位)will satisfy a porter. At lower-end buildings don’t feel you have to tip Like Bangkok, many taxis are now metered so you can just round up to the nearest ringgit．
Seoul
Tipping is not part of Korean culture, although it has become a matter of course in international hotels where a 10％ service charge is often added．If you’re at a Korean barbecue joint(烧烤处),there’s no need to add anything extra．But a nice Italian restaurant may require a 10％ contribution．
If you’re at a top-end hotel, so expect to pay 500～l,000 won per bag．Taxi drivers don’t accept a tip．Keep the change for yourself．
( )57．Which of the following is NOT the unit of money?．
A．Charge B．Baht C．Won D．Ringgit
( )58．In which of the following cities is it unnecessary to tip the taxi-drivers?
A．Bangkok B．Hongkong C．Kuala Lumpur D．Seoul
( )59．If you stay at a five-star hotel in Kuala Lumpur, how much will you pay the porter at least?
A．10％ of service charge B．Two ringgit C．Half a ringgit D．One ringgit
( )60．The writer seems ．
A．to tell the readers how to travel
B．to give the readers some advice on how to tip
C．to ask the readers to go on a travel to Asian cities
D．to make the trip more pleasant
Heading out for some exercise? You’ll take your shoes, socks, and a towel．You might take a music headset．But you’ll also need a bottle of water．Here is why．When you exercise, you sweat. Sweating is your body’s way of cooling down．The more you sweat, the more water your body loses．However, exercise also reduces thirst If you’re not thirsty, you may not drink enough water．You could lose too much water and become dehydrated(脱水)．A water loss of 10 percent can make you sick．A loss of 20 percent can kill you. So you need to be careful．
Here’s how to keep your body hydrated．About two hours before you exercise, drink one 500millilitre(1/2litre)bottle of water．Then drink another half bottle right before you begin．Drink water every 20 minutes as you exercise．You’ll need water long before you’re thirsty．
You need water even when you’re not exercising．You should drink about five bottles of water each day．Why so much? Your body cells are mostly water．So is your blood. Water helps your body to digest(消化)food and remove wastes．But your body loses water as you breathe, sweat, and urinate(排尿)．It loses about 2.5 liters (2,500 milliliters)of water each day．
You must replace the water your body loses．You can get water from many sources．Drinking water is the best source．Food and other fluids are good too, All food has some water in it．Fruit and vegetables are high in water Milk, juices, and other drinks also contain water．So take your pick．And remember to drink more water when you exercise．A happy body is a hydrated body．
( )53．The passage suggests that each day you should drink .
A．about 2,500 milliliters of water B．about 500 milliliters of water
C．as much water as you can D．only when you get thirsty
( )54．What are some ways to replace water your body has lost?
A．Taking baths and eating eggs．
B．Drinking juice and eating vegetables
C．Digesting food and removing wastes．
D．Eating many kinds of food and exercising．
( )55．After reading the whole passage, we learn it is mainly about ．
A．the results of research on dehydration

Speeding off in a stolen car, the thief thinks he has got a great catch. But he is in for an unwelcome surprise. The car is fitted with a remote immobilizer (锁止器), and a radio signal from a control centre miles away will ensure that once the thief switches the engine off, he will not be able to start it again.
The idea goes like this. A control box fitted to the car contains a mini-cellphone, a micro- processor and memory, and a GPS (全球定位系统) satellite positioning receiver. If the car is stolen, a coded cellphone signal will tell the control centre to block the vehicle's engine management system and prevent the engine being restarted.
In the UK, a set of technical fixes is already making life harder for car thieves. “The pattern of vehicle crime has changed,” says Martyn Randall, a security expert. He says it would only take him a few minutes to teach a person how to steal a car, using a bare minimum(="smallest)" of tools. But only if the car is more than 10 years old.
Modern cars are far tougher to steal, as their engine management computer won't allow them to start unless they receive a unique ID code beamed out by the ignition (点火) key. In the UK, technologies like this have helped achieve a 31% drop in vehicle-related crime since 1997.
But determined criminals are still managing to find other ways to steal cars, often by getting hold of the owner's keys. And key theft is responsible for 40% of the thefts of vehicles fitted with a tracking system.
If the stolen car travels 100 metres without the driver confirming their ID, the system will send a signal to an operations centre that it has been stolen. The hundred metres minimum avoids false alarms due to inaccuracies in the GPS signal.
Staff at the centre will then contact the owner to confirm that the car really is missing, and keep the police informed of the vehicle's movements through the car's GPS unit.
57. The remote immobilizer is fitted to a car to ______.
A. allow the car to lock automatically when stolen
B. help the police make a surprise attack on the car thief
C. prevent the car thief from restarting it once it stops
D. prevent car theft by sending a radio signal to the car owner
58. By saying “The pattern of vehicle crime has changed”, Martyn Randall suggests that ______.
A. it takes a longer time for the car thief to do the stealing
B. self-prepared tools are no longer enough for car theft
C. the thief has to make use of computer technology
D. the thief has lost interest in stealing cars over 10 years old
59. Why does the tracking system set a 100-metre minimum before sending an alarm to the operations centre?
A. To allow for possible errors in the GPS system.
B. To give the driver time to contact the operations centre.
C. To keep the police informed of the car's movements.
D. To leave time for the operations centre to give an alarm.
60. The operations centre will first ______ after receiving an alarm.
A. start the tracking system. B. contact the car owner.
C. block the car engine. D. locate the missing car.
Scott Langteau has this message for kids: Spend less time playing video games.
It’s a message that many a mom and dad have tried to impress upon many a youngster (and some not-so-youngsters) who spend perhaps a bit too much time with game controllers in hand.
But the 40-year-old Langteau isn’t a parent. He’s experienced at video games – one who played producer on three “Medal of Honor” games and co-founded his own game development company.
Langteau has just published a children’s book called Sofa Boy, which tells the story of a kid who spends too much time sitting on the couch with controller held in hand and the rather terrible consequences that follow.
It’s a fairy tale picked straight from Langteau’s own experiences as a lad with a fondness for video games and his painful struggle against game addiction. But first, Langteau would like to make one thing clear: I’m not saying that you shouldn’t play video games. I think video games are great; I think they do great things for kids. Instead, Langteau says his book is all about a little something called “moderation ”. “Anyway, you’ve got to stop before going too far.”
“It’s all about being well rounded,” he says. “Just like with anything else, we all need to make sure that there’s a variety in what we do.”
Video gamers can be rather bad-tempered when it comes to accepting criticism about their favorite entertainment. After all, most people who go round talking about the dangers of playing video games tend to be outsiders – people who don’t play video games and certainly don’t understand that they can be a valuable and healthy form of entertainment.
But Langteau and Sofa Boy seem to be a unique position to deliver a message of gaming moderation that the young game masses might actually listen to. After all, this is a man who understands what it means to be a kid with passion for games. His early experience has taught him a lesson.
