Have you heard about "Survival (生存) Holidays"? "Survival Holidays" is for children to go into the lonely place for exciting activities. Now about 1,100 companies are allowed to take children into the great outdoors without their parents.
The reason why people like "Survival Holidays" is that they think being close to nature is good for children. Many children in big cities spend all time watching TV and playing computer games. "Survival Holidays" gives them an important change.
Is "Survival Holidays" a wonderful idea? Maybe it is. Children need more free time to play. They need to be left on their own, without adults disturbing (打扰) them. Parents care too much about their children. They like to see the children being busy with activities that are controlled by adults, but children don't know what to do when they are in danger. Even something like crossing a small river seems to be a hard challenge. Children are not comfortable with danger. Even small danger like getting their feet wet or falling down seems very terrible to them.
Many people think the survival activities are good for children. Even years later, they will still remember what they have learned. Some have learned to stay calm in different times. Some have learned how to keep safe. Others have learned how to work in a team. All these skills will help them a lot in their lives.

In the United States, parents usually encourage their children to develop their potential (潜能). They pay attention to what their kids can do, not what they can't. As a result, US boys and girls hope to be actors, athletes and doctors; many even want to become presidents when they grow up.
US parents often encourage their children to take part in all kinds of activities at school. They believe that joining in these activities can make their children mature(成熟). Schoolwork is important, but they think that social skills are important as well.
But things in China are different. Chinese parents often tell their children to study hard and pass exams. They think that, for a student, staying away from schoolbooks means wasting time.

If you go to a fast food restaurant, you will probably see a lot of teenagers. Today, many teenagers are overweight, and this is because of their bad eating habits. Most teenagers are keen about food with a lot of fat, oil, salt and sugar. People call this kind of food "junk food".
But bad eating habits go beyond fast food. We find many teenagers eat unhealthily. Some don't have breakfast before they go to school. During the day, some don't have a proper meal for lunch. In a recent survey at one school, scientists found that over two thirds of the students didn't follow a healthy diet. They didn't like vegetables, and many of them didn't like to eat fruits. They preferred to eat food with a lot of salt, sugar, or fat.
Parents today also worry about their children's diet. Some doctors give the following advice:
Teenagers shouldn't eat too much junk food.
Teenagers shouldn't eat food with too much salt. Salt can cause high blood pressure in the future.
Teenagers should eat food without much fat, oil and sugar.
Teenagers need to eat some fruits and vegetables every day. Fruits and vegetables are rich in vitamins（维生素）and have little fat.
Teenagers need to drink more milk. Milk will help their bones grow.
Teenagers need to eat breakfast every day. It is good for their body and mind.
56. How many pieces of advice are given by the doctors in the passage?

Children are amazing! They①pick up languages so naturally and easily. Have you ever wondered why? It's not because they have great natural language abilities.②In fact, studies show that an adult's potential(潜能) to learn language is as good as a child's .
So why do children still seem to acquire(学到) languages more quickly than the rest of us? It's because of the way they learn. Children learn by simply doing what comes naturally-they listen, copy and communicate. Let's take a closer look at how children ac quire languages. Perhaps we can discover a better, more "natural" way to learn English.
Children don't practice grammar drills, but use languages to talk about things that interest them. This helps them learn to express themselves. They don't worry about inadequate(不足的) vocabulary or poor grammar. They find ways to express themselves, and they do it successfully.
③Students should pay more attention to genuine(真实的) communication. Look for chances to talk with people in English. If you can't find a foreigner to talk to, talk with other English students instead. Start an English discussion group and chat about music, movies or whatever interests you.
Don't worry about making mistakes. The aim is to learn how to communicate easily and comfortably. Remember that you can communicate successfully even with a small vocabulary.
Trust your own natural ability to learn English. You've got more potential than you probably realize!
61.在文中找出① 处划线短语的同义词。
62.将文中②处划线句子翻译成汉语。
63. Do children worry about poor grammar when they learn to express themselves?
64.将文中③处划线句子改为被动语态。
Genuine communication should more attention to by students .
65. As a student, how should you learn language by reading the passage?
答案：61. acquire /learn （任意答对一个都给2分）
62. 实际上/事实上，研究表明(一个)成年人学习语言的潜能和（一个）孩子的（潜能）一样好.

A hobby can be almost anything tha t a person likes to do in his spare time. Hobbyists raise pets, watch birds, paint pictures, play the piano and grow flowers. 66 They collect everything from books to butterflies and from boxes to stamps.
People take up hobbies because these activities offer enjoyment, friendship and relaxation. Hobbies help people relax after a long time of hard work, and provide a balance (平衡) between work and play. Hobbies offer interesting activities for the old. Some hobbies can make a child grow as a person, develop his interest and help him learn new skills. 67 Doctors have found that hobbies are useful in helping patients (病人) recover (恢复) from illness. Hobbies give patients who can't move around something to do, and provide interests that keep them from thinking about themselves. Many hospitals treat (治疗) patients by having them take up interesting hobbies. 68
In early times, most people were too busy making a living to have many hobbies. But some persons who had spare time did enjoy hobbies. 69 People today have m ore time than ever before for hobbies. Machines have now reduced much time that people must spend on their jobs.

Being able to multitask-doing several things at the same time-is considered (考虑，认为) a welcome skill by most people. But if we consider the situation of the young people aged from eight to eighteen, we should think again.
What we often see nowadays is that young people juggle a larger number of electronic devices (电子产品) as they study. While working, they also surf on the Internet, send out emails, answer the telephone and listen to music on their iPods. In a sense, they are spending a large amount of time in fruitless efforts (努力) as they multitask.
Multitasking is even changing the relationship between family members. As young people give so much attention to their own worlds, they seem to have no time to spend with the other people around them. They can no longer greet family members when they enter the house, nor can they eat at the family table.
Multitasking also has an effect (影响) on young people's performance at university and in the workplace . When ask ed about their opinions of the effects of modern gadgets (器具) on their performance of tasks, many young people gave a positive (肯定的) response (回应). However, the response from the worlds of education and business was not quite as positive. Educators feel that multitasking by children has a serious effect on later development of study skills. They believe that many college students now need help to improve their study skills. Similarly, employers (雇主) feel that young people entering the job market need to be taught all over again, as modern gadgets have made it unnecessary (没必要) for them to learn special skills to do their work.

When I was a kid in Minnesota, watermelon was expensive. One of my father's friends, Bernie, was a rich businessman, who owned a large store in St. Paul.
Every summer, when the first watermelons arrived, Bernie would call. Dad and I would go to Bernie's place. We' d sit on the edge of the dock（码头）, feet dangling（摇晃）, and got ready for a big meal.
Bernie would take his knife, cut our first watermelon, hand us both a big piece and sit down next to us. Then we'd bury our faces in watermelon, eating only the heart-the reddest, juiciest, firmest, sweetest, most seed-free part-and throw away the rest.
Bernie was my father's idea of a rich man. I always thought it was because he was such a successful businessman. Years later, I realized that it was not Bernie's wealth itself but his way of dealing with it that my father liked. Bernie knew how to stop working, get together with friends and eat only the heart of the watermelon.
What I learned from Bernie is that being rich is a state of mind. Some of us, no matter how much money we have, will never be free enough to eat only the heart of the watermelon. If you don't take the time to dangle your feet over the dock and enjoy life's small pleasure, your work is probably hurting your life.
For many years, I forgot that lesson I'd learned as a kid on the loading dock. I was too busy making all the money I could.
Well, I've relearned it. I hope I have time left to enjoy the success of others and to take pleasure in the day. That's the heart of the watermelon. I have learned again to throw the rest away.
46. We learned from the second paragraph that the writer and his father were feeling ______.
A. relaxed B. worried C. hungry D. proud
47. How did the writer and his father eat the watermelon?
A. They ate it in a polite way. B. They only ate its best part.
C. They ate every part of it. D. They shared only one piece.
48. In the eyes of the writer's father, Bernie ______.
A. was just a rich businessman B. worked hard all the time
C. lived a rich but healthy life D. knew how to make money
49. The underlined part "the heart of the watermelon" in the last paragraph refers to ______.
A. the best part of the watermelon B. the writer's busy life
C. the writer's decision of making money D. the writer's hope of enjoying life
50. It can be learned from the passage that ______.
A. one has to work hard to reach his goal B. a friend in need is a friend in deed
C. watermelon is the healthiest fruit D. one should keep work-life balance

When the Audet family turns on the lights at Blue Farm, they are using electricity that comes from cows-cow manure (粪肥), to be specific.
Cows produce a lot of wastes. One cow can create 30 gallons of wastes each day. Now imagine the output of over 1,000 cows at Blue Farm. That's really a big amount.
When farmers clean their barns, they put the wastes in a big heap, and spread some of them on their fields for fertilizer(肥料). But now places like Blue Spruce Farm have a new way of using cow wastes. They use them to produce electricity.
Here's how it works: A big machine moves back and forth cleaning the barn floor. "The cows aren't bothered," says Marie Audet. "They are animals of habit; they get used to it, and just lift one foot and then another to let it go by."
The machine pushes the manure into a big 600-gallon tank like a small swimming pool. The tank is called a digester (化粪池) because what happens there is just like what happens inside a cow: Bacteria(细菌) get to work and continue to digest the manure.
Methane gas (甲烷、沼气)in the atmosphere is known as a "greenhouse" gas because it keeps heat just like a greenhouse does, causing our planet to warm up. That's an environmental concern. But the digester has a good result. Its gas is kept and used to power electric generators (发电机).
At Blue Farm, the generators make enough electricity to power 400 homes. The Audet family sells the extra electricity they can't use themselves.
51. We learn from the text that the Audet family is using cow wastes to ______.
A. make electricity B. produce fertilizer C. build their farm D. feed the cows
52. How are the cow wastes collected into the digester at Blue Farm?
A. Marie Audet does the work B. The job is done by machine
C. The cows lift the cow wastes D. Bacteria get to work on them
53. According to the passage, which of the following is changed into electricity?
A. The power of moving water. B. The heat of burning coal.
C. The power of sunlight. D. The heat of the methane gas
54. The new way of using cow wastes at Blue Farm might be best descr ibed as ______.
A. reducing B. saving C. recycling D. changing
55. What is the main purpose for writing the passage?
A. To introduce a new way of making electricity B. To explain how a new energy works better
C. To show a new rebuilding plan for a big farm D. To explain the reasons for green house effect

You can have the same CD for half of the price by clicking(敲击)on your computer. And we can find any CD you want and bring it to your door in 24 hours!"
