71 It is divided into two types: short term memory and long term memory. Short term memory helps the brain to remember the information from a few seconds to a few minutes, for example, searching a phone number in the phone directory. This type of information is not stored for a long time, and slips from the brain. 72
73 There is no exact definition of brain exercises. The key to brain exercises is to stimulate(刺激) the gray cells of our mind. For example, trying out different problem solving exercises can be a good practice for improving the analytical skills of brain. 74 If you regularly exercise it, you will develop a good body, or else you will have an unfit body, and thus, our brain needs exercises regularly. Here are some memory improvement tips for adults:
●Regular exercises help to keep away diseases that are harmful to the memory. Besides, regular exercising improves the feeling of well-being and improves blood circulation to the brain.
●Don't be stressed, as stress holds back the ability of the mind to concentrate. A stress-free mind will collect and store more information that a stressed mind, so avoid being over-stressed. But in modern times people have great pressure from work and life. 75 . Sleep is necessary for keeping the mind and body fit and the side effects of lack of sleep include a lack of concentration.
| A．Ask your doctors for advice on memory. |
| B．Developing good sleeping habits helps a lot. |
| C．The memory is just like our body in some way. |
| D．Memory is the remembering of any information taken in by the brain. |
E.Not all people have the power to recite so many things at a time.
F.Long term memory, on the other hand, is the memory where we make conscious efforts to keep the information for a long time.
G.Brain exercises are one of the simplest ways of improving memory power.
Losing a baby tooth can be fun for a kid. You can put it under your pillow and look forward to finding some money there in the morning. And then you can watch your new permanent(永恒的) tooth grow in its place.
But if a permanent tooth falls out, that’s a problem. There isn’t another one under the gum(齿龈)that can replace it. Unfortunately, this happens to some older people. And if permanent teeth fall out or need to be pulled, an older person might need dentures.
Dentures, known as false teeth, are a set of replacement teeth for any teeth that are missing. There are partial dentures, which take the place of only a few teeth and prevent the others from changing position. If all the teeth are gone, the person would need complete dentures, which replace every tooth in the mouth.
Dentures can cause pains at first and take little time to get adjusted to. They also need special care. They should be brushed daily with a special denture brush and cleanser and soaked in denture solution when not in the mouth.
Dentures are important for older folks because, without teeth, it’s hard to smile, talk, and eat properly. But it can be a little weird if you see someone take out his or her dentures. It can also be strange to see someone, like a grandparent, without dentures in because he or she won’t have any teeth. Try not to make fun of the person because this could cause hurt feelings.
People usually lose their permanent teeth due to periodontal disease, or gum disease, which is caused by bacteria that attacks the gums. Diseased gums aren’t strong and healthy, so teeth can get loose and fall out. Older people often have many cavities(洞)that have been filled over the years, and these fillings can weaken over time, leading to more tooth decay.
67．If one of your baby teeth falls out, you .
A．should have a false tooth fixed in its place
B．have to put it under your pillow at once
C．will gain a permanent tooth in future
D．can exchange it for some money
68．A person wearing dentures .
A．should brush them with a special denture brush every few days
B．will take a very long time to adjust himself or herself to them
C．will experience unpleasant feelings at the beginning of fixing them
D．should use denture solution to soak them in his or her mouth
69．Which of the following is NOT true according to the passage?
A．Partial dentures can prevent the remaining teeth from changing position.
B．Old people will find it hard to smile, talk, and eat properly without teeth.
C．A person’s teeth will possibly get loose if diseases strike his gums.
D．It is hard for a person to wear dentures if all his teeth have fallen out.
70．What does the underlined word “weird” mean in the fifth paragraph?
A．inconvenient B．excited C．uncomfortable D．impolite
With smart phones taking the world by storm, a phone that can only send and receive voictcal1s and text messages may seem like a relic from a bygone age. Yet in East Africa, simple phones like these are changing the face of the economy, thanks to the mobile money services that are spreading across the region. Using the text--messaging function built into the GSM system(全球通) used by most cell phone networks, these services al1ow people without a bank account or credit card to use their/phone as an electronic wallet that can he used to store, send or receive cash.
It works like this: you pay cash to your loca1 agent who then tops up your mobile money account using a secure form of text messaging. That money can be transferred to another person by sending a message to their cell Phone account.
Fur some the system is a lifeline. ''If I didn’t have my mobile Phone, I would be very poor," says Neyasse Neemur, a mother of four chi1dren who lives in northern Kenya. .”Now I can sell fish.” Neemur took up fishing in Ju1y last year, but making money from it was a little tricky, especially as Turkana peop1e do not usually eat fish. A truck from Ethiopia to Tanzania passes through her vi1lage once a week, and she arranged to have the driver transport the fish several hundred ki1ometers south to market in Kisumu, where relatives sell the fish.
"I get the money transfer immediately.” says Neemur . "Then I can pay for my children to go to school and for vegetables and beans," she adds, "so I don't need to eat fish."
According to the Central Bank of Kenya, payments worth around l billion Kenyan shillings($13 million) per day were transferred through Kenya’s mobile money systems in 2009, equaling the country’s credit card transactions(业务). The bank expects mobile money transfers to overtake credit cards in 2010.

D. They can do nothing except send and receive calls or messages.
65. The word “It” in the third paragraph refers to _____________________.

Gloria is a famous hostess of a TV station. When she was 15, she happened to walk into a bookstore in her hometown and began looking at the books on the shelves. The man behind the counter, John Smith, asked if she'd like a job. She needed to start saving for college, so she said yes.

The sun shone in through the dining room window，lighting up the hardwood floor. We had been talking there for nearly two hours．The phone of the“Nightline”rang yet again and Morrie asked his helper．Connie，to get it .She had been taking down the callers’names in Morrie’s small black appointment book .It was clear 1 was not the only one interested in visiting my old professor—the“Nightline”appearance had made him something of a big figure—but I was impressed with．perhaps even a bit envious of，all the friends that Morrie seemed to have
“You know．Mitch，now that I'm dying，I've become much more interesting to people．I’m on the last great journey here——and people want me to tell them what to pack．”
The phone rang again．
“Morrie，can you talk?”Connie asked .

“Have you found someone to share your heart with?” he asked .
“Are you at peace with yourself?”
“Are you trying to be as human as you can be?”
I felt ashamed，wanting to show I had been trying hard to work out such questions．What
happened to me? I once promised myself I would never work for money，that I would join the
Peace Corps，and that 1 would w*w^w.k&s#5@u.c~o*mlive in beautiful，inspirational places．
Instead, I had been in Detroit for ten years，at the same workplace，using the same bank，visiting the same barber .I was thirty-seven，more mature than in college，tied to computers and modems and cell phones．I was no longer young，nor did I walk around in gray sweatshirts with unlit cigarettes in my mouth．I did not have long discussions over egg salad sandwiches about the meaning of life．
My days were full，yet I remained，much of the time，unsatisfied .

Just as mankind has always had a desire to fly, the human race has wanted to swim under the water since prehistoric times. Pictures of primitive devices to enable people to breathe underwater have been found dating from 3000 years ago, but our dream of moving freely beneath the ocean waves for long periods of time was only realized about 60 years ago, when French diving legend Jacques Cousteau developed the first practical Self Contained Underwater Breathing Apparatus(SCUBA). Since then the sport of SCUBA diving has gone from strength to strength.
Lovers of SCUBA diving like the feeling of weightlessness, the peace and quiet under the water, the ability to move in three dimensions and the sense of adventure they get while on a dive. SCUBA divers often travel to some of the most beautiful and remote places in the world in the search for rare underwater flora and fauna(动、植物). Palau, The Red Sea, The Maldives and Hawaii have many of the most popular diving sites, but recreational divers often have to make do with less exotic local destinations, like the North Sea in Britain.
SCUBA diving is not without its dangers, however. The mixture of nitrogen and oxygen divers breathe underwater, combined with the pressure under the water can be deadly if a diver rises too quickly to the surface, causing a condition called ‘the bends’. Divers can also get lost or trapped when diving on wrecks, and fatalities(死亡)are particularly common in cave diving, where divers add to the dangers of diving by swimming through underground caves filled with water. Diving can also be harmful to the underwater environment. However with proper precautions diving can open up a whole new world, far from the stresses of daily life.

When did you see a polar bear ? On a trip to a zoo, perhaps ? If you had attended a winter activity in New York a few years ago, you would have seen a whole polar bear club. These “Polar Bears” are people who meet frequently in the winter to swim in freezing cold water. That day, the air temperature was 3 degrees. And the water temperature was a little higher. The members of the Polar Bear Club at Coney Island, New York are usually about the age of 60. Members must satisfy two requirements. First, they must get along well with everyone else in the group; this is very important because there are so many different kinds of people in the club. Polar Bears must also agree to swim outdoors at least twice a month from November through February.
Doctors don’t agree about the medical effects of cold-water swimming. Some are worried about the dangers of a condition in which the body’s temperature drops so slow that finally the heart stops. Other doctors, however, point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and the water tempreature is much greater in summer than in winter.
The Polar Bears themselves are satisfied with the benefits of cold-water swimming. They say that their favorite form of exercise is very good for the circulatory system (循环系统) because it forces the blood to move fast to keep the body warm. Cold-water swimmers usually turn bright red after a few minutes in the water. A person who turns blue probably has a very poor circulatory system and could not try cold-water swimming.
The main benefits of cold-water swimming are probably mental. The Polar Bears love to swim all the year round; they find it fun and relaxing. As one 70-year-old woman says, “When I go into the water, I pour my troubles into the ocean and let them float away.”

A. have different ideas about the medical effects of cold-water swimming

3. The Polar Bears like to swim year-round, for _______ .
A. it is an easy way to keep the body warm in winter

There are several reasons for hair loss in women. However, in most cases, treatment is quite effective. Female hair loss patterns in women are not as easily recognizable as they are in men. A woman may experience it temporarily due to pregnancy or illness, although they may experience it for other reasons.
Hair loss can be due to a variety of factors, including a genetic tendency (which is not genetically linked to just one parent—both parents contribute to the tendency to lose hair).
Women who are experiencing hair problems seem to have more limited choices than men. There are some female hair loss treatments that are available such as the Tricomin System which is a topical treatment that is nutrition based. Shen Min for Women is another natural treatment that contains herbs (药草) that are said to stimulate(刺激) hair growth and even restore hair that is graying to its natural color.
The majority of the popular, proven hair loss treatments are only intended for men and are not suitable for women. True, a woman’s hair issue is different from a man’s. The biological makeup is different and the needs are different. Women have different needs and their bodies react in different ways to environmental changes, physical illness and even the treatments that are available. There are many natural treatments such as vitamin and mineral supplements that are said to stimulate hair growth, but, for the most part, these claims are currently unproven.
One of the first and most important factors to effectively treating is to get a diagnosis from a doctor. Talk to your doctor about any symptoms that you may be experiencing in addition to the thinning hair. Stress, weight loss or gain, illness and depression, all of these can be contributing factors.
50. It can be learned from the 1st paragraph that ___________.
usually hair loss is hard to heal
B . female hair loss is more common than the men’s
women tend to suffer from hair loss during the pregnant period
only illness contributes to hair loss
51.Which of the following statements matches the text about the two treatments?
A. Both are to solve the problem of male hair loss.
Tricomin System is effective in speeding the growth of the new hair
Shen Min is an updated way of treating hair loss
D. The former is nutrition-based, while the latter is medicine-based.
52. The reasons for the differences between the female and male hair loss problems do not include _______.
A. The biological structure and composition of the hair
The wants and needs
The reactions and responses to the outside changes
The approach to taking exercise
53. The natural treatments __________.
include vitamin and mineral supplements
B. are applied to keep the hair healthy
C. have been proved useful
D. are the most commonly-used ways
One hundred and thirteen million Americans have at least one bank-issued credit card. They give their owners automatic credit in stores, restaurants, and hotels, at home, across the country, and even abroad, and they make many banking services available as well. More and more of these credit cards can be read automatically, making it possible to withdraw or deposit money in scattered locations, whether or not the local branch bank is open. For many of us the “cashless society” is not on the horizon---it’s already here.
While computer offer these conveniences to consumers, they have many advantages for sellers too. Electronic cash registers can do much more than simply ring up sales. They can keep a wide range of records, including who sold what, when and to whom. This information allows businessmen to keep track of their list of goods by showing which items are being sold and how far they are moving. Decisions to reorder or return goods to suppliers can then be made. At the same time these computers record which hours are busiest and which employees are the most efficient, allowing personnel and staffing assignments to be made accordingly. And they also identify preferred customer for promotional campaigns. Computers are relied on by manufacturers for similar reasons. Computer analyzed marketing reports can help to decide which products to emphasize now, which to develop for the future and which to drop. Computers keep track of goods in stock, of raw materials on hand, and even of the production process itself.
Numerous other commercial enterprises, from theaters to magazine publishers, from gas and electric utilities to milk processors, bring better and more efficient services to consumers through the use of computers.
49.According to the passage, the credit card enables its owner to .
A. withdraw as much money from the bank as he wishes
B. obtain more convenient services than other people do
C. enjoy great trust from the storekeeper
D. cash money where he wished to
50. From the last sentence of the first paragraph we learn that .
A. in the future all the Americans will use credit cads
B. credit cards are mainly used in the United States today
C. nowadays many Americans do not pay in cash
D. it is now more convenient to use credit cards than before
51. The phrase“ring up sales”most probably means .
A. make an order of goods B. record sales on a cash register
C. call the sales manager D. keep track of the goods in stock
If you are in charge of a project, the key to success is getting everyone to want to help you. As a director, I point, I suggest. I gently push the actors in the direction I want them to go. In the 1986 movie, “Nothing in Common”, Jackie Gleason’s character, Max Basner, gets fired from his job as a clothing salesman. The scene, shot on a boat, shows Max’s despair about being out of work. I was looking for some gesture that would allow Max to show his feelings.
Jackie had far more experience at everything than I did, and at first I was frightened. What could I possibly tell “The Great One” about acting? Finally I decided to direct by suggestion, and sat down with Gleason to talk about the scene. “So Max is sad, right?” I said.
Gleason nodded.
“And he’s probably still carrying his pens with name on them—the ones he used to hand out to his customers, right?”
Gleason nodded.
“So what would you want to do with the pens after you were fired?”
He was silent for a moment. “Why don’t I throw them overboard?”
I stood up and turned up and turned toward the crew. “Hey, everybody, Jackie has a wonderful idea. Let’s shoot it.”
After filming the scene, Gleason called me over and said with a smile. “Garry, what kind of wonderful idea am I going to have tomorrow?”
You and your team can discover the answers to problems together. When there are no prizes or gold stars for who gets the solution first, you’ll all benefit when everything turns out right.
61.According to the writer, to succeed in a project you are in charge of , you should______.
A. make everyone work for you B. get everyone willing to help
C. let people know you have the idea D. keep talking to them
62. “The Great One” in Paragraph 2 refers to______.
A. Gleason B. the director himself C. Max D. Max’s boss
63. After filming the scene, Gleason called the director over and smiled at him. That’s because Gleason________.
A. thought the director gave him a good idea
B. formed the habit of thinking of ideas while talking
C. was not confident about his acting
D. appreciated the director’s directing skill
64. The most suitable title for the passage is “_______”.
A. Directing a Film B. The Key to Success
C. A Wonderful Experience D. Working with Film
It is a typical case. A young professional has just moved to a new city. She is very active in her new job but wishes to meet people socially outside of work. How does she do this？
Signing up for a night class is always a good starting point. Not only is it an ideal way to meet like-minded people，it can also be a great new learning experience. Pubs and clubs can be a good meeting place but can be a bit hard if you are on your own.
Join a gym
GL-14 health club in Manchester city centre is a gym which also has lots of member activities outside the gym from charity fashion shows to dinner dances giving members a chance to socialize away from the treadmill（繁忙的工作）. Or if you want a gym with a difference，try a“Green Gym”for people who want to exercise but wish to be outdoors and doing something that will benefit the environment at the same time. The“work out”could involve such activities as practical conservation or gardening work. It’s a great way to get people’s heart and muscle working. And many agree that meeting other people and having a matter and a laugh is a big attraction of the scheme.
Reading groups
In the Reading Groups，Jenny Hartley suggested that there may be as many as 50，000 people in reading groups in the UK. They range from informal groups of friends or colleagues who meet in someone’s home or at the local pub，to discuss a book. If you want something a bit more structured，lots of libraries have reading groups and could have a broader group of members.
Statistics
The BBC recently conducted a survey called Going solo：single life in the 21st century. You can look at the overall results or search by area. It found that：
*69％ of people thought that the gym was a good place to meet new
*Pubs or clubs were considered to be good meeting places by 58％ of people in the UK
*68％ thought that work was a good place to meet people
*72％ thought that internet chat was not an ideal way to meet people

Everywhere you look, large quantities of information in the world are pouring. This data flood is already starting to transform business, government, science and everyday life. It has great potential for good — as long as consumers, companies and governments make the right choices about when to restrict the flow of data, and when to encourage it.
A few industries have led the way in their ability to gather and take advantage of the data. Credit-card companies monitor every purchase and can identify cheats with a high degree of accuracy. Stolen credit cards are more likely to be used to buy hard liquor than wine, for example, because it is easier to overlook. Insurance firms are also good at combining clues to spot doubtful claims: dishonest claims are more likely to be made on a Monday than a Tuesday, since policyholders (保险客户) who stage accidents tend to assemble friends as false witnesses over the weekend. By combining many such rules, it is possible to work out which cards are likeliest to have been stolen, and which claims are untrue. By analyzing “basket data”, supermarkets can make promotions to appeal to particular customers’ preferences. The oil industry uses supercomputers to help them before drilling wells.
But the data flood also poses risks. There are many examples of databases being stolen: disks full of social-security data go missing, laptops loaded with tax records are left in taxis, credit-card numbers are stolen by online purchase. The result can be privacy made public, identity stolen and cheats permitted large space. Rather than owning and controlling their own personal data, they very often find that they have lost control of it.
The best way to deal with the data flood is to make more data available in the right way, by requiring greater transparency in several areas. First, users should be given greater access to and control over the information held about them, including whom it is shared with. Google allows users to see what information it holds about them, and lets them delete their search histories or modify the targeting of advertising, for example. Second, organizations should be required to disclose details of security breaches (安全漏洞), as is already the case in some parts of the world, to encourage bosses to take information security more seriously. Third, organizations should be subject to an annual security check, with the resulting grade made public (though details of any problems exposed would not be). This would encourage companies to keep their security measures up to date.

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 (发动机防盗系统), 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 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 of tools, but only if the car is more than ten 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 key (汽车等的点火开关).
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 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 police informed of the vehicle’s movements via the car’s GPS unit.
56. What’s the function of the remote immobilizer fitted to a car?
A. To allow the car to lock automatically when stolen
B. To prevent the car thief from restarting it once it stops
C. To help the police make a surprise attack on the car thief
D. To prevent car theft by sending a radio signal to the car owner
57. By saying “The pattern of vehicle crime has changed” (Lines1-2,Para.3) Martyn Randall suggests that _____.
A. Self-prepared tools are no longer enough for car theft
B. the thief has to make use of computer technology
C. it takes a longer time for the car thief to do the stealing
D. the thief has lost interest in stealing cars over 10 years old
58. What is essential in making a modern car tougher to steal?
A. A GPS satellite positioning receiver
B. A unique ID card
C. A special cellphone
D. A code ignition key
59. Why does the tracking system set a 100-metre minimum before sending an alarm to the operations centre?
A. To give the driver time to contact the operation centre
B. To allow for possible errors in the GPS system
C. To keep police informed of the car’s movements
D. To leave time for the operations centre to give an alarm
Your cellphone holds secrets about you. Besides the names and numbers that you’ve programmed into it, traces of your DNA remain on it, according to a new study.
DNA is genetic material that appears in every cell. Like your fingerprint, your DNA is unique to you - unless you have an identical twin. Scientists today usually analyze DNA in blood, saliva （唾液）or hair left behind at the scene of a crime. The results often help detectives identify criminals and victims.
Meghan J. McFadden, a biologist at McMaster University in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cellphone and later dropped it. This made her wonder whether traces of DNA remained on cellphones - even when no blood was involved. To find out, she and a colleague collected flip-style （翻盖式）phones from 10 volunteers. They collected invisible traces of the users from two parts of the phone: the outside, where the user holds it, and the speaker, which is placed at the user’s ear.
The scientists cleaned the phones using a liquid mixture made mostly of alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones back for another week. Then they returned the phones and the researchers collected traces on each phone once more. They discovered DNA that belonged to the phone’s owner on each of the phones.
Surprisingly, DNA was even picked up immediately after the phones were cleaned. That suggests that washing won’t remove all traces of evidence from a criminal’s cellphone. So cellphones can be added to the list of clues that can settle a crime-scene investigation.
64. In a crime-scene investigation, now experts are likely to turn to ________.
A. the criminal’s fingerprint B. the DNA analysis of physical items
C. the detectives D. the criminal’s cellphone
65. According to the passage, McFadden was inspired by ________.
A. the secrets stored in people’s cellphones B. the special characters of DNA
C. a cellphone-involved case D. the challenging job of detectives
66. According to the passage, the potential application of the new study would be ________.
A. identifying criminals B. designing new cellphones
C. protecting individual privacy D. preventing cellphone-involved crimes
67. Which of the following has the closest meaning with the underlined word “identify” in Paragraph 2?
A. imagine B. recognize C. discover D. determine
