Do you think of white when someone talks about a polar bear? In fact, the polar bear does not have white fur. It just appears to be white. Polar bears have a very good sense of smell. It helps them to find food. During summer, polar bears sleep longer, because they are able to find their food more easily at night. Usually, after a meal, polar bears have a short sleep. A polar bear can have 2-3 babies at a time. They live with their mothers until they are about two-and-a-half years old.
However, polar bears will die out soon because of people. There are only 20,000 to 25,000 polar bears in the world. The ones that are left are trying to survive today. The number of polar bears is becoming smaller and smaller because of the loss of sea ice— polar bears mostly inhabit (居住于) the sea ice, not the land ice. This is happening because of global warming (全球气候变暖), pollution, hunting and so on.
Ordinary people don"t care, but great people have the power and want to save tigers, fight for giant pandas and save polar bears. Ordinary people will wait, but great people will find a new world. For me, I will not waiting. I will take the bus more often from now on. Join me and save the polar bears, and, of course, the tigers, the giant pandas and...

Here is an interview with a painter. Read and choose the best.
Reporter:Mr Shum, you were one of Taiwan’s most outstanding youths last year. Why was that?
Mr Shum:Well, I can tell you that there are two reasons.First, I am a painter. Second, and more important reason is I am handicapped﹙残疾的﹚。I have no arms and only one leg.
Reporter:Well, how do you paint then if you’ve got no arms? Do you use your foot?
Mr Shum:Hah! For some handicapped people, it’s true and they are able to use their feet.No,I use my mouth. I put my paintbrush or my crayons or pencils or whatever I am using in my mouth. I hold it firmly in my teeth and paint or draw like that. It was a little strange for me at first, but it quickly became very easy.
Reporter:I know you feel that you are first a painter and only secondly that you are a disablbed person, but can we talk first about your handicap?
Mr Shum:Well,in fact I think of myself firstly as a person, secondly as a painter and thirdly as someone with a physical handicap. Can I say that I am not happy with the word “handicapped”?
I am a popular painter because my paintings are good, not because they were painted by a handicapped person. “handicapped”means you can’t do anything. It is difficult for me to do some things like getting dressed.

It may seem easy to say that plants and animals are different. Any child can tell the difference between  a tree and a dog. But those differences are far deeper than just what they look like. The cells (细胞) that plants are made up of are different. In other words, the cell wall of plants has something special.

First of all, it"s important to find that not all plant cells have a cell wall. Besides, there are many differences of a cell wall based on the kinds of plant. The following is meant to be what a plant cell wall is  like.
The cell wall of a plant is on the outside of the cell membrane (膜). It is usually hard and cannot be bent easily, but the degree of flexibility (韧性) of the cell wall is different. It is based on the special use that the cell has in keeping the plant alive. Cells that make up the trunk of a tree are clearly less flexible than  cells on a leaf.
Cell walls act in many ways. They serve to protect the plant. They provide support, as well as help in the movement of chemicals and wastes into and out of the cell.  More importantly, they control the water  that goes in and out.  Plants must have good water controlling systems (系统), allowing them to keep water during dry seasons, and get rid of unnecessary water. Plants can"t walk around to find water, so  being able to control water is very important.
So there you have it , what a plant cell wall is. Of course, there are many other things that are not talked about here. Knowing more about plant cell wails requires further study and research.
小题1:From the first two paragraphs we can find that _____.
A.all plants have a ceil wall
B.plant cells and animal cells are the same

D.there are no differences between the cells of a tree and a dog
小题2:The underlined word "bent" in the passage is the closest in meaning to _____.
A.变形的B.防水的C.太阳灼伤的D.表皮破损的
小题3:Cells in the trunk of a tree are _____ those on a leaf.
A.as flexible asB.not so flexible as
C.more important thanD.less important than
小题4:What is the most important use of a plant cell wall?
A.To protect the plant.B.To provide support.
C.To move chemicals and wastes.D.To control the water.
