To be able to motivate oneself, or self-motivate, occurs when a person has the willingness to do something and is internally(内在地) motivated to do it.
Sometimes it’s very difficult to get ourselves moving. The natural tendency is to postpone. Life just seems to get in the way! There is a job to go to, groceries to do, television to watch—whoops! I guess we get pretty good at finding excuses to escape getting started on goals like an exercise routine or reading a new book. The fact is that we are creatures of routine and habit. So what can we do to motivate ourselves to accomplish our goals?
Here are some tips on how to get moving:
l Decide what you want. It’s hard to motivate an aimless mind. Set a goal and decide how you are going to go about it. Then break it down into smaller sections so it’s easier to handle and less overwhelming.（势不可挡）
l Keep track of your progress. Keep a log or journal where you can measure how much you have accomplished. Looking at it can also motivate you to keep pushing ahead.
l Post motivating pictures or slogans within your sight. It is always inspiring to see pictures of people who have accomplished what you’re going for. It makes it attainable and realistic. Likewise, little slogans like “go for it” or “just do it” can give you the little support you need.
l Sometimes we forget what we set out to do and a little reminder is all we need to be revitalized (激活) and focus on the end result. If you remind yourself to go for the desired promotion, it will re-establish why you are doing what you’re doing.
l Make it a habit. Once you have accomplished your objective, e.g. becoming an early riser, keep it up so that it’s second nature to you and you don’t have to think about it anymore.

John Steinbeck once said, “All Americans believe they are born fishermen. For a man to admit to a distaste in fishing would be like denouncing (公开指责) mother – love or hating moonlight.”
I can’t say that I’m the biggest John Steinbeck fan. Actually, the only thing I can ever remember reading by him was “The pearl” when I was in middle school, but I couldn’t agree more with the man when it comes to fishing. Whether I am on a boat in the middle of the Lay Lake, fishing off the shores of the Florida Keys for tarpon (大海鲢) or catching rainbow trout (红鲭鱼) in the Shoshone River of Wyoming, fishing is my life.
According to the American Sports Fishing Association, the fishing industry brings in more than $ 116 billion per year from fishermen across the country.
Though a beautiful picture to imagine fishing is much more than that. Fishing is a way of life for many people and a way to escape everyday stress. Being a fisherman makes me a member of a wonderful group of people extending to all walks of life. Even President Bush can be found fishing on his farm in Texas with his good friend Roland Martin when the job gets too stressful.
I can remember fishing with my grandfather when I was 5 years old on his boat at Lake Mitchell. Although I didn’t understand what I doing. I did know that my grandfather was happy and that made me happy. Since then I’ve spent the past 16 years on the rivers and lakes of Alabama.
After days of practice, before and after work, I slowly developed an understanding of fishing. My boss. Ric Horst, took me back to the Shoshone, and I managed to bring in a 19 – inch cutthroat trout. Fishing with Ric was a life – changing experience for me. He not only showed my how to fish correctly, but also told me how fishing could be a way to escape your problems.
Since then, prime – time (黄金时间) season seems to take forever to arrive.
Now, with the ending of February and beginning of March in sight, the excitement of heading out Lake Tuscaloosa or Lake Lurleen before classes and catching something has finally returned.

Although the weathermen’s forecasts for a month ahead are only little better than guesswork, they are now making long-term forecasts into the next century with growing confidence. The main trend in the world’s climate in the coming years will, scientists say, be a predictable result of man’s activities.
At the start of the industrial revolution nearly two centuries ago, man set off a big experiment in planetary engineering. Unaware of what he was doing, he spared no thought for the consequences. Today the possible outcome is alarmingly clear, but the experiment is unstoppable. Within the lifetime of many of us, the Earth may become warmer than it has been for a thousand years. By the middle of this century it may be warmer than it has been since the last Ice Age.
A warmer climate may seem welcome, but it could bring many dangers： damages to crops in the world’s main food-producing areas, famine(饥荒), economic instability, civil unrest and even war.
In the much longer term, melting of the great ice-caps of Greenland and Antarctica could raise sea-levels throughout the world. The average sea-level has already risen a foot since the turn of the last century, and if the ice-caps disappear completely, it would rise by nearly 200 feet. Complete melting might take many centuries, but even a small increase in sea-level would threaten low-lying parts of the world such as the Netherlands.
44. Long-term weather forecasts beyond the year 2050 may seem strange because ____.
A. none of us will be alive then
B. weathermen can even forecast next month’s weather correctly
C. weathermen can forecast much better than they used to
D. no one can stop engineering experiments
45. Weathermen believe that our future climate will be the direct result of ____.
A. the big scientific experiment B. clever long-term forecasts
C. the melting of the ice-caps D. planets changing course
46. One of the results of a warmer world climate could be ____.
A. an increase in food production
B. greater co-operation between countries
C. the death of millions of people from starvation
D. a reduction in the amount of oil we use
47. Scientists are fairly sure that by the year 2050, _______.
A. the sea-level will have risen obviously
B. there will have been the Third World War
C. most countries will have been flooded
D. the polar ice-caps will have melted completely
The most important holiday in spring, especially for Christians, is Easter. This Christian holiday is not on the same date every year，but it’s always on a Sunday. It can be any Sunday between March 22 and April 25. Many people celebrate Easter by buying new clothes. Children celebrate by hunting for colored eggs that their parents have hidden around the house. People also give Easter baskets filled with candy and other goodies to one another to celebrate the day.
But the holiday is more than new clothes and good things to eat. On Easter, many people go to church to celebrate Jesus’ resurrection（复活）from the dead. Most people color Ester eggs. Some people hide them. Others just eat them. But no matter what one does with Easter eggs，they are an important Easter tradition throughout the Western world. People from many different cultures celebrate Easter. In both America and Belgium, children look for Easter eggs hidden on lawns and in bushes. In America, children believe the eggs are hidden by the Easter bunny (兔子).But in Belgium, the hidden eggs are supposed to have fallen from church bells. In Bulgaria (保加利亚), red Easter eggs are lucky in churches. Bulgarian families also hit these Easter eggs together to see whose is the strongest. The winner looks forward to good fortune that year. Still dozens of other Easter traditions exist. In parts of Austria，for example，children sing from door to door and are rewarded with colorful eggs.

As the sound of footsteps behind her grew louder, she quickened her pace. She didn’t want to turn around as the memory of that morning’s newspaper headline made her afraid of what she would see: “City Killer Claims Fourth Victim.”
“Why did I stop for a few drinks in the bar after work?” she thought to herself. Now it was dark and the streets deserted. She was alone and a sitting duck.
She felt as if she was walking in the rain. Her clothes were damp from nervous sweat and as each short hot breath hit the night air, it turned to steam, coating her glasses in a thin film so all she saw seemed covered in fog.
The footsteps were closer now. She needed to get off this street. Her eyes began a useless search for an open store or lighted window. Passing a small lane she looked through, for a possible escape route. But the lane was a dead - end and she laughed to herself at the irony ( 具有讽刺意味的事 ).
The sound of a car behind her turning onto the street interrupted her self – pity. Escape was at hand. But as she was about to throw herself onto the road and shout for the car to stop, the car’s headlights cast a shadow that paralyzed ( 使瘫痪 ) her with terror.
It was the footsteps’ owner. The figure was huge and in its raised arm it held what looked like a lead-pipe, no doubt the one that was about to claim victim number five.
The shadow dissolved as the car passed by and disappeared into the distance. She felt a hand on her shoulder. It was all happening as if in slow – motion. She was waiting for her life to flash before her eyes like all those novels said it would – but it didn’t. The only thing she thought of was her dear husband. She recalled phoning him from work that very afternoon and joking about, of all things, the city killer. It was a night full of ironies.
There was a voice talking to her now but she was lost in thoughts of her fate and didn’t respond. The hand then began turning her around. It was surprisingly gentle given what was about to come. She allowed it to guide her without resistance ( 抗拒 ).
She looked up. She recognized the face, but she didn’t know from where. Its mouth was still talking to her but she couldn’t understand. Then she remembered. The face belonged to the foreign looking man who had served her at the bar. She looked down to his hand and saw in it not a lead – pipe but a rolled up copy of a work report she had been correcting in the bar as she drank.
His words suddenly started to register in her brain and she could hear him. “Miss, Miss. Are you OK? You left this in the bar and it looked important so I thought I’d better give it to you.”
71. The woman was feeling nervous because .
A. she had left her report in the bar
B. there was a killer in the city

Parking has long been a major headache for drivers in Shanghai. The Transportation Department is mapping out a new plan for the city’s parking system. There are one million cars on the road in Shanghai but only enough public parking space to provide room for 15 percent of these vehicles. It is no wonder that local drivers get so worried trying to find a place to park.
The city is seeing a rise in private car owners. In March, the city sent out 2,000 private car licenses, the highest number of licenses ever sent out in a month. And prices rose to 14,600 yuan, 500 more than in February. Industry experts say this suggests that local people have a strong, active interest in buying cars.
By the year 2020, the number of automobiles in Shanghai will probably reach two million. If one parking lot is for each car, then a lot of parking space should be built for these vehicles.
Downtown Shanghai is most short of parking space. However, experts point out that simply building more parking lots in downtown areas is not practical and doesn’t provide an ideal solution. The idea of “ Park & Ride” system has been suggested. This means that drivers can leave their vehicles in car parks nearby subway or bus stations and ride public transport to go downtown. Based on this idea, the city will limit the number of parking lots in downtown areas and demand higher parking fees but build more parking areas near main subway and bus stops.
72.The underlined phrase “ mapping out ” in the first paragraph means __________.
A. making B. arguing C. controlling D. inspiring
73. About __________ drivers can find places to park their cars in Shanghai now.
A. 850,000 B. 1,000,000 C. 150,000 D. 2,000,000
74. What does the second paragraph mainly tell us ?
A. The city sent out more private licenses in February.
B. Less and less people bought cars in March.
C. The city sent out less private licenses in March.
D. More and more people are going to buy cars.
75. According to the idea of a “ Park & Ride ” system, the city will __________.
A. send out more private car licenses
B. build more parking lots near bus stops
C. encourage people to buy more cars
D. build more parking areas in downtown
When you take a walk in any city, you often see a lot of people walking dogs. It is still true that a dog is the most useful and faithful animal in the world, but the reason why people keep a dog has changed. In the old days people used to train dogs to protect(保护) themselves against attacks by other beasts. Later they came to realize that a dog was not only useful for protection but willing to obey his master. For example, when people used dogs for hunting, the dogs would not eat what was caught without permission.
These days people in the city need not protect themselves against attacks from animals. Why do they keep dogs, then? Some people keep dogs to protect themselves from robbery（抢劫）. But the most important reason is for companionship. For a child, a dog is a best friend when there are no friends to play with. For young couples, a dog is their child when they have no children. For old couples, a dog is also their child when their natural children have grown up. So the main reason why people keep dogs has changed from protection to friendship.

Computer programmer David Jones makes 35,000 pounds a year designing new computer games, yet he cannot find a bank prepared to let him have a credit card (信用卡). Instead, he has been told to wait another two years, until he is 18.
The 16-year-old boy works for a small firm in Liverpool, where the problem of most young people of his age is finding a job. David’s firm puts two new games on the home market each month.
But David’s biggest headache is what to do with his money. In spite of his salary, made by inventing new programs within a quite short period of time, the bonus payments and profit-sharing (奖金和分红), he cannot drive a car, get some money from a bank to buy a house, or get credit cards.
He lives with his parents in their house in Liverpool, where his father is a bus driver. His firm has to pay ￡150 a month in taxi fares to get him the five miles to work and back every day because David cannot drive.
David got his job with the firm a year after leaving school with six 0-levels and working for a time in a computer shop. “I got the job because the people who run the firm knew I had already written some programs,” he said.
“I suppose 35,000 pounds sounds a lot but actually that’s not good enough. I hope it will come to more than that this year.” He spends some of his money on records and clothes, and gives his mother 20 pounds a week. But most of his spare time is spent working.
“Unfortunately, computing was not part of our studies at school,” he said. “But I had been studying it in books and magazines for four years in my spare time. I know what I wanted to do and never considered staying on at school. Most people in this business are fairly young, anyway.”
David added, “I would like to earn a million and I suppose early retirement (退休) is a possibility. You never know when the market might disappear.”
36. Why is David different from other young people of his age?
A. He earns a very high salary.
B. He has not a job.
C. He does not go out much.

When you turn on the radio, you hear an advertisement. When you watch television, you hear and see an advertisement. If you turn the pages of a newspaper or magazine, again you find an advertisement. If you walk down the street, you see one advertising board after another. All day, every day, people who want to sell you something compete to catch your attention. As a result, advertisements are almost everywhere.
In the West, advertisements are the fuel (燃料) that makes mass media work. Many TV stations, newspapers, magazines, radio stations are privately owned. The government does not give them money. So where does the money come from? From advertisements. Without advertisements, there would not be these private businesses.
Have you ever asked yourself what advertising is? Through the years, people have given different answers to the question. For some time it was felt that advertising was a means of “keeping your name before the public”. And some people thought that advertising was “Truth well told. Now more and more people describe it in this way: Advertising is the paid, non-personal, and usually persuasive (有说服力的)description of goods, services and ideas by identified (明确的)sponsors through various media.
First, advertising is usually paid for. Various sponsors pay for the advertisements we see, read, and hear over the various media. Second, advertising is non-personal. It is not face-to-face communication. Although you may feel that a message in a certain advertisement is aimed directly at you, in reality, it is directed at large groups of people. Third, advertising is usually persuasive. Directly or indirectly it tells people to do something. All advertisements try to make people believe that the product, idea or service advertised can do good to them. Fourth, the sponsor of the advertisement must be identified. From the advertisement, we can see if the sponsor is a company, or an organization, or an individual. Fifth, advertising reaches us through traditional and nontraditional mass media. Included in the traditional media are newspapers, magazines, radio, television, and films. Nontraditional media include the mail, matchbox covers, and billboards (广告牌).

The first thing to remember about homework is that it needs to be done as soon as you get home from school. Since many parents do not give doses to help you sleep at night, the homework MUST be done first. If you have after-school activities, the homework should be done as soon as you get home. It is fine to allow for a snack break and also to allow for stretching breaks. Every kid of you really needs these little breaks.
Also, you should remember that it is your responsibility to do your homework. Next time you tend to depend on Mom and Dad for a roadmap, please try to struggle with it first, because it is good for you.
When you have questions, especially something about a science or a math problem, don’t always turn to your teacher! It is a good idea to struggle with them first and try to work them out. Sometimes, if this doesn’t work, look at the materials in the back of the book. They may guide you to pages and and understanding everything completely.
At last, while doing homework, don’t be looking away but continue working. Setting time limits often helps with this. Different ages decide different fair amounts of time. 10-15minutes is good for a child that’s age 6-8. A time of 20-30 minutes is about right for a child aged 9-12. Kids can achieve 30-45 minute intervals of study at age 13-15. This, of course, depends on your abilities to concentrate and stay on task.
60. The passage mainly tells children ________.
A. to do their homework quickly and properly

D. homework in science needs more time
Scientists have devised a way to determine roughly where a person has lived using a strand (缕) of hair, a technique that could help track the movements of criminal suspects or unidentified murder victims.
The method relies on measuring how chemical variations in drinking water show up in people’s hair.
“You’re what you eat and drink, and that’s recorded in your hair,” said Thure Ceiling, a geologist at the University of Utah.
While U.S. diet is relatively identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as rain clouds move.
Most hydrogen and oxygen atoms in water are stable, but traces of both elements are also present as heavier isotopes (同位素). The heaviest rain falls first. As a result, storms that form over the Pacific deliver heavier water to California than to Utah.
Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can construct a geographic timeline. Each inch of hair corresponds to about two months.
Cerling’s team collected tap water samples from 600 cities and constructed a map of the regional differences. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops.
They were able to accurately place the hair samples in broad regions roughly corresponding to the movement of rain systems.
“It’s not good for pinpointing (精确定位),” Ceding said. “It’s good for eliminating many possibilities.”
Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton was found near Great Salt Lake.
The woman was 5 feet tall. Police recovered 26 bones, a T-shirt and several strands of hair.
When Park heard about the research, he gave the hair samples to the researchers. Chemical testing showed that over the two years before her death, she moved about every two months.
She stayed in the Northwest, although the test could not be more specific than somewhere between eastern Oregon and western Wyoming.
“It’s still a substantial area,” Park said. “But it narrows it way down for me.”
61. According to the passage scientists’ new discovery is that .
A. One’s hair growth has to do with the amount of water they drink.
B. A person’s hair may reveal where they have lived.
C. Hair analysis accurately identifies criminal suspects.
D. The chemical composition of hair varies from person to person.
62. The underlined sentence “You’re what you eat and drink” (Line 1, Para. 3) means .
A. Food and drink affect one’s personality development.
B. Food and drink preferences vary with individuals.
C. Food and drink leave traces in one’s body tissues.
D. Food and drink are indispensable to one’s existence.
63. Which of the following is true of the rainfall in America’s West?
A. There is much more rainfall in California than in Utah.
B. The water it delivers becomes lighter when it moves inland.
C. Its chemical composition is less stable than in other areas.
D. It gathers more light isotopes as it moves eastward.
64. Cerling’s team produced in their research?
A. a map showing the regional differences of tap water
B. a collection of hair samples from various barber shops
C. a method to measure the amount of water in human hair
D. a chart illustrating the movement of the rain system
65. What is the practical value of Cerling’s research?
A. It helps analyze the quality of water in different regions.
B. It helps the police determine where a crime is committed.
C. It helps the police narrow down possibilities in detective work.
D. It helps identify the drinking habits of the person under investigation.
As bananas ripen， the green skin turns ye11ow gradually. Chemical changes occur in the f1esh of the fruit as well：starch（淀粉）changes to sugar；pectin（果胶）breaks down，losing its stiffness； and the f1esh softens.
Is ripening fruit a self－contained system， or is the rate of these changes affected by the environment？ We designed the experiment below to see if different atmospheres， produced by different packaging， affected the rate of ripening. You will vary the atmosphere surrounding unripe bananas and observe the effect on the ripening process。
Now set up the bananas in their environments as follows：
1. Put two green bananas in a paper bag and fo1d the top over to seal out the air.
2．Put one green banana and the very ripe banana in the other paper bag and fold over the top.
3. Put two green bananas in a plastic bag and seal it.
4. Wrap（包）one green banana tightly in a plastic bag.
5. Leave one green banana exposed to the air.
Leave the fruit a1one or five days to ripen. Ripening fruit“breathes”． This means that it takes up oxygen and gives off C02. Oxygen is extremely important and necessary for the chemical reactions involved in ripening. In addition, ripening fruit gives off another gas, called ethylene（乙烯）. Not only is ethylene a product of ripening fruit, it also promotes the further ripening of the fruit.
Paper bags tend to keep the ethylene in, but they allow oxygen and ethylene to pass through slowly. Plastic bags do not allow the free flow of oxygen or ethylene. In this experiment, the green banana in paper bag with the ripe banana should ripen most quickly. The green bananas in the paper bag should ripen faster than the bananas in the plastic bag. The banana left exposed to air has an unlimited supply of oxygen, so it will turn brown most quickly. You will notice that the side of this banana that rests on the counter will ripen more quickly than the other sides, because it has the
closest contact（接触）with its own ethylene. The banana that is tightly wrapped in plastic has no oxygen supply and should ripen most slowly. Now can you see why bananas are sealed in plastic in many supermarkets？
