The United States government wants to know what the public thinks about its findings on the safety of cloned animals．
The Food and Drug Administration says meat and milk from clones of adult cattle, pigs and goats are safe to eat．An FDA official called them “as safe to eat as the food we eat every day．” And when those clones reproduce sexually, the agency says, their offspring(后代)are safe to eat as well．But research on cloned sheep is limited．So the FDA proposes that sheep clones not be used for human food．
The United States this year could become the first country to agree to the sale of foods from cloned animals．First, however, the public will have ninety days to comment on three suggested documents．On December 28th the FDA released a long report, called a draft risk assessment, along with two policy documents．
The agency says it must receive comments by April second．The FDA seemed ready to act several years ago, but a committee called for more research．
For now, the government will continue to ask producers to honor a request that they not sell foods from cloned animals．
Clones are still rare．They cost a lot and are difficult to produce．
The FDA says most food from cloning is expected to come not from clones themselves, but from their sexually reproduced offspring．It says clones are expected to be used mostly as breeding animals to spread good qualities．
Public opinion studies show most Americans do not like the idea of food from cloned animals．But this research also shows the public knows little about cloning．
Cloning differs from genetic engineering．A cell taken from a so-called donor animal is grown into an embryo(胚胎) in the laboratory．Next, the embryo is placed into the uterus(子宫) of a female animal．If the process is successful, the pregnancy reaches full term and a genetic copy of the donor animal is born．
60．What’s the main purpose of the passage?
A．To tell a interesting story． B．To give some advice on foods．
C．To give a report． D．To compare different opinions．
61．Who believe that foods from cloning are safe to eat?__________
A．Most Americans B．An advisory committee
C．Critics D．The FDA
62．It can be inferred from the last paragraph that_____．
A．cloning has much in common with genetic
B．not every cell taken from a donor animal can grow into a genetic copy
C．the donor animal should be a female one
D．cloned animals grow faster than normal ones
63．Which of the following is true about foods from cloning?_______________
A．They come from the sexually reproduced offspring of cloned animals．
B．The food from first-generation cloned animals is very expensive．
C．Only FDA has the right to sell the food．
D．They will be sold mixed with those from naturally bred animals．

Each year, prizes are presented to adults who accomplish great things in art, writing, science, and economics．So why not give awards to kids?
Harry Leibowitz asked himself that question in 1996．As an answer, he and his wife, Kay, created the World of Children organization and began handing out awards to kids and adults whose work has helped kids all over the world．The awards World of Children presents are nicknamed the "Children's Nobel Prize．" On Thursday, World of Children honored six adults and two kids at its 11th Annual Changemakers for Children awards ceremony held at the UNICEF House at United Nations Plaza in New York City．
Talia Leman, from Iowa, was awarded a Founder's Youth Award for Leadership．She is only 13 years old, but she has accomplished a lot．In 2005, she founded "RandomKid．" Since then, the nonprofit organization has raised more than $10 million to help kids in 48 states in the U．S．and in 19 other countries develop funding solutions to real-world problems．One place helped by RandomKid was a school built in Cambodia to enable 300 kids to go to school．The organization has also helped fix a school for 200 kids in Slidell, Louisiana, and provided interactive play centers that serve more than 500 kids in hospitals in Iowa．In faraway places like Africa, RandomKid has provided money for the purchase of water pumps．
Talia never thought that the organization she founded would be as successful as it has become．"I did a project called TLC, which meant Trick or Treat for the Levy Catastrophe, where kids would trick-or-treat for coins along with getting candy," she told me．"My goal was to raise $1 million．That seemed really high, but when you reach a goal, you always wind up reaching higher--and we actually raised $10 million．" The money RandomKid raised provided help to the victims of hurricanes Katrina and Rita．

There are two types of people in the world. Although they have equal degrees of health and wealth and other comforts of life, one becomes happy the other becomes miserable. This arises from the different ways in which they consider things,persons,and events, and the resulting effects upon their minds.
The people who are to be happy fix their attention on the conveniences of things: the pleasant parts of conversation, the well-prepared dishes, the goodness of the wines, and the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the contrary things. Therefore, they are continually discontented. By their remarks, they sour the pleasures of society, offend many people, and make themselves disagreeable everywhere. If this turn of mind were founded in nature, such unhappy persons would be the more to be critical. The tendency to criticize and be disgusted is perhaps taken up originally by imitation. It grows into a habit, unknown to its possessors. The habit may be strong,but it may be cured when those who have it are convinced of its bad effects on their interests and tastes. I hope this little warning may be of service to them, and help them change this habit.
Although in fact it is chiefly an act of the imagination, it has serious consequences in life since it brings on deep sorrow and bad luck. Those people offend many others, nobody loves them, and no one treats them with more than the most common politeness and respect, and scarcely that. This frequently puts them in bad temper and draws them into arguments. If they aim at obtaining some advantage in rank or fortune, nobody wishes them success. Nor will anyone stir a step or speak a word to favor their hopes.
If they bring on themselves public disapproval, no one will defend or excuse them, and many will join to criticize their misconduct. These people should change this bad habit and condescend (俯就) to be pleased with what is pleasing, without worrying needlessly about themselves and others. If they do not, it will be good for others to avoid any contact with them. Otherwise, it can be disagreeable and sometimes very inconvenient, especially when one becomes mixed up in their quarrels.
People who are to be unhappy . .
A. always act differently from others.
B. usually have a fault-finding habit.
C. can discover the unpleasant part of certain things.
D. usually are influenced by the results of certain things
One of the consequences of the unhappy people's remark is that .
A. they are not content with the pleasure of society.
B. they are bad-temper but friendly.
C. they hate everything
D. they are hurt.
74. Which of the following statements is true according to the passage?
A. We should pity such unhappy people.
B. Such unhappy people are content with themselves.
C. Such unhappy people are critical almost with themselves.
D. Even such unhappy people recognize the bad effects of the habit on themselves, but they can not get rid of it.
75. If such unhappy people don’t change their bad behavior, the author’s solution to the problem is that people should .
A. help them B. avoid contact with them
C. pay no attention to themD. show no respect to them

Soil conservation efforts protect soil from wind and water that can blow or wash it away. Good soil produces food crops for both people and animals.
One important form of soil conservation is the use of windbreaks (防风林). Windbreaks are barriers formed by trees and other plants with many leaves. Farmers plant them in lines around their fields. Windbreaks stop the wind from blowing soil away. They also keep the wind from destroying or damaging crops. They are very important for growing grains, such as wheat.
For example, in parts of West Africa, studies have shown that grain harvests can be twenty percent higher on fields protected by windbreaks compared to those without such protection.
Windbreaks are effective when a wall of trees and other plants blocks the wind. The windbreaks should also limit violent motions of the wind to those areas closest to the windbreak.
However, windbreaks seem to work best when they allow a little wind to pass through. If the wall of trees and plants stops wind completely, then violent air motions will take place close to the ground. These motions cause the soil to lift up into the air where it will be blown away. For this reason, a windbreak is best if it has only sixty to eighty percent of the trees and plants needed to make a solid line.
An easy rule to remember is that windbreaks can protect areas up to ten times the height of the tallest trees in the windbreak.
There should be at least two lines in each windbreak. One line should be large trees. The second line, right next to it, can be shorter trees and other plants with leaves.
Windbreaks not only protect land and crops from the wind. They can also provide wood products. These include wood for fuel and longer pieces for making fences. Locally-grown trees and plants are best for windbreaks.
68. What does this text primarily concern?
A. A way to protect soil. B. Some advice on growing windbreaks.
C. The effect of windbreaks. D. A way to protect crops.
69. Which of the following is NOT true about windbreaks?
A. If windbreaks stop the wind completely，the soil will be blown away above the windbreaks.
B. Leaving sixty to eighty percent of the trees and plants needed to make a solid line is a best windbreak.
C. A better windbreak should be two lines or more with the same height.
D. Windbreaks work best during an area up to ten times the height of the tallest trees in them.
70. The underlined word "barriers" (Para. 2) refers to .
A. something that is built with trees together with other plants
B. a structure built to forbid passage of wind with trees or other plants.
C. something used to help things control their movement.
D. narrow lines where trees and other plants with many leaves are planted.
71. Which of the following is most likely to show the right area that a windbreak can protect?

Downloading music over the Internet is pretty common among high school and college students. However, when students download and share copyrighted music without permission, they are against the law.
A survey of young people’s music ownership has found that teenagers and college students have an average of more than 800 illegally copied songs each on their digital music players. Half of those surveyed share all the music on their hard drive, enabling others to copy hundreds of songs at any one time. Some students were found to have randomly linked their personal blogs to music sites, so as to allow free trial listening of copyrighted songs for blog visitors, or adopted some of the songs as the background music for their blogs. Such practices may be easy and free, but there are consequences.
Sandra Dowd, a student of Central Michigan University, was fined US$7,500 for downloading 501 files from LimeWire, a peer-to-peer file sharing program. Sandra claimed that she was unaware that her downloads were illegal until she was contacted by authorities. Similarly, Mike Lewinski paid US$4,000 to settle a lawsuit（起诉）against him for copyright violation（违反）. Mike expressed shock and couldn’t believe that this was happening to him. “I just wanted to save some money and I always thought the threat was just a scare tactic（战术）.” “You know, everyone does it,” added Mike.
The RIAA (Recording Industry Association of America), the organization that files lawsuits against illegal downloaders, states that suing（控告）students was by no means their first choice. Unfortunately, without the threat of consequences, students are just not changing their behavior. Education alone is not enough to stop the extraordinary growth of the illegal downloading practice.
64. Why is it common for students to download copyrighted music?
A. They don’t think that they will be caught.
B. They want their friends to know that they are smart.
C. They think it is a good way to make some extra money.
D. They are against copyright protection over Internet music.
65. What does Mike mean by saying that “the threat was just a scare tactic”?
A. One should not be afraid of threats.
B. A lawsuit will result from the threat.
C. It is unfair to scare people with a threat.
D. No serious consequence will follow the threat.
66. What is RIAA’s attitude towards students’ illegal downloading behaviour?
A. They believe that education will help greatly in protecting copyrights.
B. They profit from the fines illegal downloaders pay for copyright violations.
C. They like to sue students for downloading music illegally from the Internet.
D. They think that illegal downloading behavior needs tough measures to correct.
67. What’s the best title for this passage?
A. Copyright Violators, Beware!
B. How to Get Free Music Online!
C. A Survey of Students’ Downloading Habits
D. get rid of Illegal Music Download? Impossible!
