We know that many animals do not stay in one place. Birds,fish and other animals move from one place to another at a certain time. They move for different reasons: most of them move to find food more easily,but others move to get away from places that are too crowded.
When cold weather comes,many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration(遷移)is probably the migration of the fish which is called “salmon”.This fish is born in fresh water but it travels many miles to salt water.There it spends its life. When it is old,it returns to its birthplace in fresh water. Then it gives birth and dies. In northern Europe, there is a kind of mouse. They leave their mountain homes when they bccome too crowded. They move down to the low land. Sometimes they move all the way the seadide,and many of them are killed when they fall into the sea.
Recently, scientists have studied the migration of kind of lobster(龍蝦).Every year, when the season of the bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody know where they go.
So,sometimes we know why humans and animals move from one place to another,but at other times we don’t. Maybe living things just like to travel.

DNA is the whole “map” of the human body. It is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own.
People have been trying to understand the human body for a long time, In1860, Mr Mendel discovered why we look the same as other people in our family. It is because of small things called “genes”(基因) in our body. In 1953, two scientists, Watson and Crick, found out that those small parts are really messages . They’re written in the DNA with a special language.
In1961, another two scientists found the first “word” that they could understand in that language. It shows how DNA tells the cell﹙細(xì)胞﹚to build its parts. So far, scientists have 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 to save people from several illness. So the more we understand, the more doctors will be able to do.
Most people hope that this will help to make better medicine and help sick people. Other people worry that when we learn more “words” and find out more information, we will use it in the wrong way, just to make people more attractive (有吸引力的),or stop sick people getting jobs.

A. In 2000. B. In 1961 C. In 1953 D In 1860

On Thanksgiving Day, a teacher asked her class of first-graders to draw a picture of something they were thankful for. She thought that these children from poor families actually had little to be thankful for. And she found most of them drawing pictures of flowers or tables with food. The teacher was very surprised to see the picture Douglas handed in. It’s a hand, a simple hand.
But whose hand? The class were very interested in the strange picture. “I think it must be the hand of God that brings us food,” said one child. “A farmer,” said another, “because he grows beautiful flowers.” Finally when the others were at work, the teacher went over Douglas’ desk and asked whose hand it was. “It’s your hand, Teacher,” he said quietly and shyly.
She remembered that she had often taken Douglas, a dirty lonely child, by the hand while having a class break. She often did that with the children. But it meant so much to Douglas. Perhaps this is everyone’s thanksgiving, not for the material things we get, but for the chance, in whatever small way, to give to others.
【小題1】Whose hand did Douglas draw?
A.The farmer’s. | B.God’s. | C.The teacher’s. | D.His own hand. |
A.He was good at drawing it. | B.His teacher asked him to draw it. |
C.He wanted to show his thanks to the teacher. | D.He hoped to get a prize in drawing. |
A.He was a lonely child. | B.He was very active in class. |
C.He always kept his hands clean. | D.He often answered questions loudly. |
A.The teacher went over Douglas’ desk and talked to him. |
B.Different people show their thanksgiving in different ways. |
C.The teacher often took Douglas by the hand after class. |
D.Most of the students were drawing pictures of flowers or tables with food. |
