 Scientists have made the world’s first human-sheep----with the body of a sheep and half-human organs(器官). Amazing, but true. The sheep is15percent human and 85 percent sheep. The breakthrough(突破)makes it possible to use animal organs in human bodies in the future. Professor Esmail Zanjani of University of Nevada, US, has spent seven years And over $9 million on the work. Zanjani took stem cells(干细跑) from the human body and put them into the sheep while it was still in its mother’s body. The stem cells made other cells that grew into organs. Zanjani believe that in the future such sheep might be used to help humans. Two months later a human-sheep is born, it has a liver(肝脏), heart, ling(肺) and brain that are part-human. These organs could be used to help people in need of them. There are different opinions about his work, however. Some say that scientists don’t have the right to create new creature(生物). Using animal organ might bring animal viruses(病毒) into human bodies. Others are afraid that the work might change sheep. But Professor Anjani has said that this is impossible.

You may not have heard the words “freshman fifteen” before, but they are very important for students who are entering university(大学). A freshman is a first-year college student. “Fifteen” means fifteen pounds---the fifteen pounds added to a student’s weight in his or her first year. There are a number of reasons why first-year university students gain(增加) weight; but it’s encouraging to know that freshmen don’t have to add these harmful fifteen pounds.
Mistakes choosing food
University kitchens serve(供应) many kinds of food. Some students choose unhealthy food, because now their patents are not nearby to help them choose. Some students visit the kitchen many times while studying. Late at night, some students get harmful fast food such as fish and chips with Coke to drink. Students also have less time for walking, running, and doing sports because of their schoolwork.
Eating right
If you’re careful, you don’t have to add fifteen pounds. Here are some ideas:
Think more about what you eat.
Eat plenty of vegetables and healthy meats.
Don’t eat desserts full of sugar; have fruit after dinner.
Try not to eat so much unhealthy food while you study.
It’s all right to have a little fast food sometimes---but not often.
Write down the foods you eat.
Walk, run, do sports---move and you will feel better!
Remember that the “freshman fifteen” can happen to anyone. Talk to your friends about it. Together, try to eat healthy food and not to eat unhealthy food. Walking, running, and playing sports is always more fun with friends. Help each other and you can have a healthy and happy freshman year.
小题1:The “freshman fifteen” is _______.
A．weight that high school students gain
B．weight that first-year university students can gain
C．fifteen pounds of food that first-year students eat
D．fifteen students who eat unhealthy food
小题2:Which of these mistakes is not mentioned（提及）in the passage?
A．Choosing unhealthy food.B．Visiting the kitchen while studying.
C．Getting fast food at night.D．Eating too much chocolate.
小题3: Which of these ideas would the writer probably agree with?
A．You’d better not eat unhealthy food.
B．Not eating unhealthy foods is easier with friends’ help.
C．Gaining fifteen pounds can help you study better.
D．Some students can eat anything they want.
Fishing is a popular activity and every fisherman knows the rule: Keep the big ones, throw the smaller ones back. The idea behind Lt is simple - the larger fish are probably older. If you keep the smaller ones, they won’t be able to reproduce, and the fish population is in danger.
But fishing out the largest fish from a population has an unwanted effect: Over time, fewer adult fish get really big. If only the smaller fish reproduce（繁殖）, then future generations become smaller. This is an example of evolution（进化） in action.
One scientist, Dr David Conover has spent the last decade studying the effects of the “keep the big ones” rule and if they can be reversed（颠倒）.
To set up his experiment, Conover and his team caught hundreds of silverside fish and divided them into six groups. For two groups, Conover followed the “keep the large ones” rule and took out the biggest fish. For two other groups, he removed only the small fish.
For the last two groups, he removed fish at random (随意的).
After five years, he measured the fish in each group. In the two groups where the largest fish were regularly removed, the average fish size was smaller than the average size in the other groups. Here was evolution in action: If only small fish survive to reproduce, then future generations of fish will also tend to be small.
For the second five years of his experiment, Conover changed the rules and took fish randomly from each group. At the end of the experiment, he found that the fish that were in the “keep the large ones” group for the first five years had started to get larger again, although he calculated it would take at least 12 years for the fish in that group to return to their original size.
In other words, it takes less time to shrink(变小) than it does to recover.
小题1: The underlined word “it” (Line 2) refers to “           ”
A．the activityB．the fish
C．the ruleD．the fisherman
小题2:Why do many people follow the “keep the big ones, throw the small ones back” rule?
A．It helps to protect fish numbers.
B．It helps to protect fish size.
C．It is the custom in most countries.
D．They will be punished if they don’t.
小题3:What did Conover find after the first five years of his experiment?
A．The “keep the big ones” rule made no difference to fish size.
B．The “keep the big ones” rule made fish smaller on average.
C．The “keep the big ones” rule made the fish bigger on average.
D．The “keep the big ones” rule affected all fish populations in the same way.
小题4: What is the author’s intention in writing this article?
A．To encourage people to fish more carefully.
B．To urge governments to change the rules of fishing.
C．To describe the results of a scientific experiment.
D．To introduce the rules of fishing to readers.
London used to be “foggy”（ 有雾的） for the same reason that cities like Beijing or Chongqing are “foggy” today. The “fog” was in fact smog（烟雾）, a mixture of smoke and fog．In other words, it was made by air pollution. In London, some of this pollution came from factories, but much of it came from the coal(煤)that people burnt in their houses to keep warm during the winter. By the 1950s, London’s smog problem had become so bad that the government decided to do something to clean the air. A new law was made and nobody could burn coal in any British city. In a few years, the air became much cleaner. There were no more “pea-soupers”.
Many Chinese cities now face the same sort of problem with air pollution that London faced 40 or 50 years ago. However, this problem is more difficult for Chinese cities to solve. One reason is that more of the pollution comes from the factories, rather than from coal burnt in people’s houses. If these factories were closed, this would harm the economy and lots of people would lose their jobs. Another reason is that changing from coal to cleaner fuel(燃料), like gas, is quite expensive.
However, the air in many Chinese cities is becoming cleaner and cleaner, as the government and people pay more and more attention to cutting down pollution. As a result, there are fewer “pea-soupers” in Beijing than there used to be.
小题1:What was the main reason for air pollution in London?
A．There was too much smoke in the sky．
B．There were too many factories in the city．
C．People burnt too much coal in the houses．
D．The city was too big for the cleaners to clean．
小题2:What does the underlined word “pea-soupers” refer to?
A．SmogB．Smoke
C．GasD．Coal
小题3:Which sentence is Not true?
A．Air pollution is serious in Beijing and Chongqing．
B．Using coal is much more expensive than using gas．
C．Factories made much more pollution in China．
D．The reasons of air pollution in London and Beijing are different
How quickly can you count from one to ten? Do you use ten different words to do it? Can you do it in English, or do you have to use your first languages? Do you count on your fingers? Many people think that numbers and math are the same all over the world. But scientists have discovered that it is not true.
People in different parts of the world use different ways to count on their fingers. In the United States, people think begin counting with their first fingers, which they extend or stick out. They then extend the rest of their fingers and finally the thumb(拇指）to count to five. Then they repeat this with the other hand to get to ten. In China, people count by using different finger positions. In this way, a Chinese person can easily count to ten on only one hand.
Besides ways of finger counting, scientists have found that cultures and languages are also different when it comes to numbers. Some languages have only a few words for numbers, and others have no words for numbers. A group of scientists studied aboriginal(土著的）people in Australia. These people don’t have hand movements to stand for numbers. They don’t even have word for numbers. However, they are still able to understand different ideas about numbers.
In a similar study, researchers from the Massachusetts Institute of Technology discovered that people of the Piraha tribe(部落） in northwestern Brazil don’t have words for numbers such as “one” or “three.”. They are not able to say “five trees” or “ten trees” but can say “some trees,” “more trees,” or “many trees.” Professor Edward Gibson said that mist people believe that everyone knows how to count, “but here is a group that does not count. They could learn, but it’s not useful in their culture, so they’ve never picked it up.”
Although all humans are able to understand quantities(数量）,not all languages have numbers and not all people use counting. Number words in a certain language are a result of people needing numbers in their daily lives. Now we know that people have different ideas about numbers and math, too.
小题1:The writer begins with the four questions in order to______.
A．make a surveyB．interest readers
C．tell a storyD．solve math problems
小题2:What do we learn from the difference in finger counting between the U.S. and China?

D．People of different cultures use the same way of finger counting.
小题3:Which of following is true about aboriginal Australians?

C．They can only count to five on their fingers
D．They can understand different ideas about numbers
小题4:The study of the Piraha tribe shows that____
A．people all over the world know how to count
B．People of the tribe have words for number
C．Some groups of people are not smart enough to count
D．Counting is not useful in the culture of the tribe
小题5:What is the main idea of the passage?
A．people from different cultures have different ideas about numbers and math
B．Chinese people can count more easily on their fingers than Americans
