On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could now read the whole “map” of the human body: DNA. DNA is something that everybody has, and it tells the body what to do. DNA is the reason that we look like our mother and father, because we get some of their DNA to make our own.
People have been trying to understand the human body for a long time. In 1860, Gregor Mendel discovered a special reason why we look the same as other people in our family. It is because of small things named “genes” in our body. In 1953, James Watson and Francis Crick made another discovery and found out that those small parts are real messages written in the DNA with a special language.
  In 1961, Marshall Nirenberg and Johann Matthaei found a message in DNA showing how DNA tells the cell (细胞) to build its parts. Scientists have now found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one “word” means, we can help save more people from several illnesses.
  Most people hope that this will help make better medicine and help sick people. Other people worry that when people begin to know more words and find out lots of other information, we might use it in a wrong way, just to make people more attractive, or stop sick people from getting jobs. Man would have to meet a lot of trouble if DNA technology (技术) wasn’t limited (限制) in use.
小题1:When did we first know why we look like other people in our family?
A.In 1860.B.In 1953.C.In 1961.D.In 2000.
小题2:What did the two scientists first discover in 1961?
A. The “map” of DNA.                     B. A new illness. 
C. The language of DNA.                   D. A message of DNA.
小题3:What can we do if we understand some “words” of the language inside the body?
A.Make people get new jobs.
B.Make medicine for illnesses.
C.Make maps of human.
D.Make people less attractive.
小题4:What do people think about this work?
A.It can cause good or bad results.
B.It can cause only good results.
C.It can cause good results but won’t work.
D.It can cause only bad results.

Tigers are strong and dangerous animals. But now they are in danger.
In the past, there were eight kinds of tigers in the world. But during the 20th century, only five were left. The number of Siberian tigers (东北虎) was about 300, but now it is less than 22. They’re in danger of dying out. If the government does nothing, we won’t be able to see them in ten to twenty years.
In order to stop people from hunting and killing wild tigers, and in order to make wild tigers more, the World Wildlife Fund (世界自然基金会) has started a program (项目) recently (最近). China and twelve other countries joined it.
However, it’s not enough. Remember that nature is a food chain (链). If we hurt and kill too many wild deer and pigs, wild tigers will die out because of hunger (饥饿). So the most important thing is to save the animals that tigers eat. In order to protect the wild tigers, we need call on (号召) more people to stop eating, hunting and killing wild animals.

Early to bed and early to rise makes a man healthy, wealthy and wise.
This is an old English saying (谚语). It means that we should go to bed early at night and get up early in the morning. If we do, we shall be healthy. We shall also be rich and clever.
Is this true? Perhaps it is. The body must have enough sleep. Children of your age need ten hours’ sleep every night. If you go to bed late, you can’t have enough sleep. Then you can’t think carefully and your homework will be wrong. You will not be wise and you may not become wealthy!
Some people go to bed late at night and get up late in the morning. This is not good for them. We should sleep at night when it is dark. The dark helps us sleep well. When the daylight comes, we should get up. This is the time for exercise. If the body is not used, it will become weak. Exercise keeps it strong.
Exercise helps the blood (血液) to move around inside the body. Blood takes nutrition (营养) to all parts of our bodies. The brains (大脑) in our heads also need blood. We think with our brains. If we keep our bodies healthy, and take exercise, we can think better!
Our bodies also need air to breathe (呼吸). Without air we will die. Get up early in the morning and we can have plenty of clean, fresh air. That will keep us healthy and happy.
根据短文内容,选择正确答案。
小题1:The old English saying tells us _______.

Learning English grammar and English vocabulary can be hard enough, but trying to understand English sayings can be more difficult. Some are just hard to figure out and others don’t make any sense at all. Here are four funny English sayings that you can use every day.
I’m happy as a clam(蛤).
Think of a clam. It doesn’t have to do anything. It just sits on a beach or on the bottom of the ocean all day doing nothing. It never has to work. That sounds like happiness, doesn’t it? If someone asks, “How are you today?” you can answer “I am happy as a clam” to let him or her know what a great mood you are in.
I wouldn’t touch that (or him/her) with a ten-foot pole.
Maybe there is a person who you don’t want to be friends with or even talk to. Well, this saying means that you dislike him or her so much that you don’t want to touch or go near him or her, even within ten feet!
You don’t have a leg to stand on.
This saying doesn’t mean that the person you’re talking to has no legs. It means that his or her argument is incorrect. He or she doesn’t have a leg to stand on because he or she has no facts to support what he or she is saying. This saying is a good way to tell people that you think they’re wrong.
Break a leg!
This saying actually means the opposite of what it sounds like. If you tell this to a person, you’re wishing him or her good luck!The saying comes from a superstition(迷信) that whatever you say aloud, the opposite will come true.
小题1:The first paragraph mainly tells us____________________.
A.learning English grammar is hard

小题4:We can learn from the passage that______________________.
A.the saying “You don’t have a leg to stand on” means someone loses his legs
