The Food and Drug Administration is, again, threatening to impose(征稅) milk and meat from cloned animals on a public that opposes the technology and its products.
Respected polls report that more than 60% of Americans think animal cloning is immoral, and that most people said they wouldn’t knowingly eat the products even if the FDA approved them. But because the FDA would allow cloned meat and milk to be sold without identifying labels, consumers wouldn’t be able to avoid them. The FDA has consistently tilted toward those who want cloned milk and meat in our food. Agency officials have repeatedly asserted that science shows cloned milk and meat are safe for humans. But the FDA has never published the complete scientific studies it says support that claim.
The argument that cloning is safe for animals is unconvincing. Cloned meat and milk offer no public economic benefits. Having cloned cows produce more milk wouldn’t reduce milk prices. US farmers produce more milk than we drink, and the government is required to buy the surplus. Since 2000, dairy support programs have cost taxpayers more than $ 5 billion.
Most important, this first decision to advance animal biotechnology raises ethical issues beyond the FDA’s expertise（專家意見(jiàn)）. Techniques used to clone animals will advance the ability to clone humans－and create animals with human genes. Neither the agency nor animal scientists are qualified to tell us whether and when it is ethically acceptable for humans to alter the essential nature of animals. We need a national discussion, including ethicists and religious leaders, to consider the wisdom of cloned and transgenic animals. Given the risk of unintended consequences, we should proceed cautiously. The president should halt further FDA action on cloning and set in motion(運(yùn)作) a process for beginning this broader discussion.
1. The author’s attitude towards cloning is __________.
A. standing in the middle      B. opposed     C. approving     D. supportive
3. In US many people buy cloned foods __________.
A. to support the new technique
B. because FDA approved them
C. because they cannot tell which is cloned food
D. because they cannot read the labels.
3. From the text we know that cloning technique ___________.
A. developed well enough to clone human beings
B. may cause unintended bad results to human beings
C. will bring more unexpected economic benefits
D. is supported by ethicists and religious leaders
4. What’s the best title of this passage?
A．Public Is Against Cloned Food     B．Benefits of Cloned Food
C．Cloned Food Is Illegal            D．Technique in Cloned Food

Directions: Read the following passage. Complete the diagram by using the information from the passage.
Write NO MORE THAN THREE WORDS for each answer.
Rest is critical to life and work and a positive attitude towards rest needs to be maintained, for enough rest is significant to our body and mind while a lack of adequate rest, as well as misleading attitudes to rest, will do great harm to our health.
Rest is vital to our ability to function at our best. Recent news stories report that scientists are learning surprising things about the importance of sleep. There is enough evidence suggesting that rest will refresh us, enabling our body and mind to work efficiently. Besides, rest is important for more than that; it is helpful in setting appropriate goals and deciding what goals to attain first. Those who are caught up in extremely busy lives lack the time to think about what they are doing and to make objective decisions, which blocks the maximization of their potential.  
On the contrary, lack of adequate rest damages brain function, so much so that sleep experts have been able to measure drops in IQ in patients who are short of sleep. Other studies have presented a negative effect on body movements in sleep-wanting subjects. It should not, therefore, be a surprise that the California Highway Patrol has stated that sleep-wanting drivers are as great a threat to road safety as are drunk drivers.
However, rest is widely misunderstood by some people. Instead of sleep, they go to pubs and clubs and claim that this kind of entertaining is rest. For example, what they call social drinking or having a smoke with friends. Nowadays, the economy forces people to drink and gamble for the sake of the circles one moves in. This is what fools claim thoughtlessly that it’s restful. The truth is that rest means not using our labor both physically and mentally, even spiritually.
We need to rest correctly and sufficiently; otherwise, tiredness and illness will occur. Without sufficient rest, good work is impossible.Rest is critical; it is not an end in itself.

Many facts suggest that children are overweight and the situation is getting worse, according to the doctors. I feel there are  36  reasons for this.
Some people blame the fact  37   we are surrounded by shops selling unhealthy, fatty foods,  _38  fried chicken and ice cream,  39  low price. This has turned out a whole generation of grown-ups  40  seldom cook a meal for themselves. If there  41  fewer of these restaurants, then probably children would buy less take-away food.
There is another argument that  42  parents for allowing their children to become overweight. I _43  this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate  44  healthy food, or are always allowed to choose  45  they eat, they will go for sweet and salty foods every time, and this  46  throughout their lives.

Here’s a quick reminder to all of you when you get stuck in a moment. Yesterday I skipped breakfast because I got up late. Because of the busy school work, I forgot my lunch. When I was finally thinking of buying my lunch, a person in need asked me if I could spare him some cash, so I decided to give him some money.
Then later in the evening, I was heading home anxiously for dinner. However, I got a call from my mom. She said that she had to work late and wouldn’t be able to prepare dinner for me. Even though there was no food in the house, I told my mom not to worry as I would surely find myself something to eat.
While I was still processing this sudden set of changes in my food choice for the day, I passed a young man with a broad smile handing out samples of crackers(薄脆餅干) at the gate of a supermarket. He gave me a packet and then said, “How about you taking some more for school tomorrow?” In response to that, I returned a warm smile to him and opened up my bag. He gladly filled it. I was excited.
Whether you call it luck or fate, I just wanted to say that somewhere out there somebody came along carrying a pocket of hope in his heart and shared a piece of with me! Somebody out there will one day do the same for you.!

Eye Facts
There are many commonly held beliefs about eyesight that are not proven facts. For example, some people believe that wearing glasses too soon weakens the eyes. But there is no evidence to show that the structure（結(jié)構(gòu)）of eyes is changed by wearing glasses at young age. Wearing the wrong glasses, however, can prove harmful. Studies show that for adults there is no danger, but children can develop loss of sight if they have glasses unsuitable for their eyes.
We have all heard some of the common myths about how eyesight gets bad. Most people believe that reading in weak light causes poor eyesight, but that is untrue. Too little light makes the eyes work harder, so they do get tired and strained. Eyestrain also results from reading a lot, reading in bed, and watching too much television. However, although eyestrain may cause some pain or headaches, it does not damage eyesight in the long term.
Another myth about eyes is that they can be replaced, or transplanted from one person to another. There are close to one million nerve fibers（神經(jīng)纖維）that connect the eyeball to the brain; as of yet, it is impossible to connect them all in a new person. Only certain parts of the eye can be replaced. But if we keep clearing up the myths and learning more about the eyes, someday a full transplant may be possible!
1. This passage is mostly about __________.
A. different types of eye problems        B. myths about eyesight
C. beliefs of eye doctors           D. eye transplants
2. One cause of eyestrain mentioned in the passage is __________.
A. wearing glasses too long      B. suffering from pain or headaches
C. reading in poor light         D. reading before going to bed
3. From the passage we can conclude that __________.
A. doctors are still learning things about eyesight
B. wearing wrong glasses is less harmful to adults
C. eye transplants have been performed successfully
D. people should not wear glasses at young age

As China’s women’s gymnastics team enjoyed the glory of winning the country’s first team Olympic gold medal at the 2008 Beijing Olympic Games，the young gymnasts took the opportunity to remind the world that they are old enough to compete．
Weeks before the Beijing Games, some international media raised questions about the ages of some of the members of China’s gymnastics team, particularly He Kexin and Jiang Yuyuan. They said the girls might be younger than 16, the minimum age for the Olympics. But the Chinese Gymnastics Association quickly provided copies of the gymnasts’ ID cards and passports, proving they are indeed old enough to compete.
In the final, He Kexin gave a clean performance on her favorite uneven bars（高低杠）, earning the second highest score after falling from the bars during qualification. “Although I fell down in the qualification, I became more confident today to make up for my mistake and I finally made it.”She said. It was a great moment for head coach Lu Shanzhen. “Our team made history today and proved to the world that we are the best.” the coach said, “The gold medal is not only for the gymnastics team，but also for the whole Chinese delegation at the Beijing Games.”
The coach owed the team’s success to a series of reforms. The Chinese team used to train a 1ot, but competed less, which led to poor results in international competitions. To improve their ability to compete and to strengthen their psychological power, the Chinese team sent more team members to compete abroad, so they could bring a competitive spirit back to the team. All six gymnasts in the Olympic team final were selected from fierce competition, and they proved themselves today.
1. Before the Beijing Games started，some international media doubted whether ________.
A. Chinese women gymnasts could win the team gold medal
B. He Kexin would fall from the bars during qualification
C. Chinese women gymnasts could make history at the Beijing Games
D. some Chinese women gymnasts were old enough for the Games
2. Which of the following statements is NOT true?
A. The international media’s doubts proved to be true.
B. He Kexin’s fall in the qualification had no bad effect on her performance in the final competition.
C. Chinese women gymnasts’ success at the Beijing Games proved that the reforms did work.
D. Each team is made up of 6 members to compete for the team gold medal in women gymnastics.
3. In the opinion of Lu Shanzhen, the key to achieving success for athletes is to________.
A. practice harder than ever                    B. experience more competitions abroad
C. have strong psychological power                    D. have a competitive spirit
4. The main purpose of the text is to________.
A. tell a story     B. provide evidence           C. give a report            D. compare opinions

First it was jogging. Then aerobics（有氧運(yùn)動(dòng)）. Not too long ago, Americans discovered race walking.
Now Americans are into a new fitness craze. They’re taking up bicycling. Over hills and down mountainsides and across quiet country roads, Americans are busily rolling along.
The number of adults who ride for fitness is around 17 million, an increase of 70 percent over four years ago. Twice as many women as men are coming to the sport. Americans are falling in love with biking because it has speed, the benefits of jogging and beautiful scenery.
Bicycling is a very appropriate sport, which is important to people who injured their knees while jogging or whose joints are aching from aerobics. And biking is a real awakening for people who have been into race walking in the past. Race walking is as dull as watching paint dry.
The most popular kind of bicycle for people who are new to the sport is the mountain bike, which has a fixed frame with wide tires and upright handles. Mountain bikes also have many gears（齒輪） to make it easier to climb hills. About 5 million Americans ride mountain bikes, compared with 200,000 who rode them only five years ago.
Costs range from about ＄130 for a bottom-of-the-line bicycle to more than ＄2,700 for an expensive bicycle.
Mountain biking has attracted some people who race down the sides of mountains like a bat out of hell. But most riders ride slowly and they rarely venture far from home.
The biking craze has brought an unexpected profit（盈利） to clothing and bicycle accessory（附屬品）makers. Last year, bikers paid ＄630 million for biking clothes and accessories.
Bicycling seems likely to continue its fantastic growth.
53. Race walking is about as dull as watching paint dry because _______

D
Everyone knows you must exercise regularly to keep good health. Indeed, staying physically fit is a big part of our culture. we consider（or rightly so）that healthy people are attractive people. Since most of us want to be attractive, there is no shortage of exercise clubs, training videos, magazines and books offering to help us stay physically fit.
Unfortunately, however, our culture doesn’t place the same emphasis on mental fitness. Although we tend to like men and women with strong, healthy-looking bodies, we don’t have the same degree of respect or attraction for smart, educated, mentally healthy people. This is a pity, because there are great rewards for people who have developed the ability to think well.
If your mind is well trained and flexible, you will be able to understand a great deal of what happens around you. And if you are also well educated --- that is, if you understand basic science, mathematics, music, art, literature, history and so on --- you will find it much easier to make good decisions throughout your life. Over the long run, this leads to a sense of control over your destiny and a much better life than otherwise.
People who are poorly educated or who don’t think well --- that is, people who are not mentally fit --- see things differently. Their world is controlled by mysterious, often malevolent（惡意的）forces. Such people live within a system they will never master, forced to follow rules they will never understand. Although it may not be obvious, most spend their lives being manipulated（控制）by others. They are told what to do, what to think, how to spend their money, and what they should and should not aspire（渴望）to in life.
In my opinion, if you want to live well, you must be able to use your mind well. For this reason, I want you to be able to concentrate, to solve problems, to understand complex ideas, and to think clearly and quickly. Such skills will make it easier for you to make informed decisions, understand current events, choose good friends, manage your money well, make wise lone-term decisions and appreciate music, art and literature.
The key to developing such skills is to enjoy learning, and to have the ability and motivation to teach yourself.
63. The writer of the passage feel disappointed that ____.
A. too little has been done to help people to keep physically fit
B. too much has been done to help people to keep physically fit
C. mentally healthy people are not as popular as physically healthy people
D. physically healthy people are not as popular as mentally healthy people
64. The underlined word “this” in the 3rd paragraph means ____.
A. the understanding of a great deal of what goes on around you
B. the understanding of basic science and mathematics
C. good training in body and mind
D. being able to make good decisions in life
65. The writer of this passage thinks those who are not mentally fit ____.
A. live a poor and mysterious life   B. can’t control over their life
C. often do what others do        D. enjoy being fooled and ruled
66. The best title of the passage will most probably be ____.
A. Train Your Body                  B. Train Your Mind  
C. Make Informed Decisions       D. Think Hard and Work Hard
