考题
AWhy do plants grow in some places and not in others? Why does some land have so much growing on it，while other land has almost no plants growing on it at all?To grow plants need several things． One is warmth． In very cold places almost nothing grows． Plants also need water． In very dry parts of the earth only a few unusual plants can grow． That's why dry deserts everywhere are almost not covered by trees or grass．Plants must also have a place in which to f，ut down their roots and grow． They find it diffi-culr to grow on hard land． The town is built on hard land． The plants here have only the soil found between the cracks of the stones Io grow in．Another thing plants must have before they can grow is food．Whar will happen if we try to make things grow on the sandy beach? A few plants，such as beach grass，will grow in sand，L ut most plants won-t． Even if the weather is warm enough．and we water the plants each day． Many of them will die because the sand on this beach has al-most no food for plants．( )21． According to the passage，plants need _________ things to grow well．A． twoB． threeC． fourD． five

材料1
Tom: Hello Alice. I'm interested in your work saving birds! What do you think is the most difficult part of your work?
Alice: Well ... I suppose it's saving wild birds covered in oil. That's the most difficult of all.
Tom: How does that happen?
Alice: The oil comes from boats. It floats on the water and covers the bird's feathers when they swim through it.
Tom: That sounds terrible. What do you do about it?
Alice: The first thing we do is to make sure the bird hasn't tried to clean itself with its beak.
As it does so, the bird eats some oil and becomes sick.
Tom: Oh dear! Do the birds always die?
Alice: Sometimes ... but we try to save them. Birds use their feathers like a raincoat to keep out cold water. When feathers are covered in oil, they stick together and a bird's skin gets cold in the water. So without help the bird would die of cold!
材料2
Scientists have discovered that when chimpanzees have stomach pains, typically because of intestinal parasites, they look for a certain plant to eat, Lippea. It is common in the jungles where chimpanzees live, and it contains chemical substances effective against many parasites.
Lippea is not the only natural medicine in the chimpanzees' cabinet. They may actually use up to thirty different plants--for different problems. Interestingly, the local people make use of many of the same plants for medical purposes. It is almost certain that chimpanzees discovered these herbal remedies before humans.

An Essential Scientific Process
All life on the earth depends upon green plants. Using sunlight, theplants produce their own food. Then animals feed upon the plants. They take inthe nutrients the plants have made sted. But that’s not all.Sunlight also helps a plant produce oxygen. Some of the oxygen is used by theplant, but a plant usually produces me oxygen than it uses. The excess oxygenis necessary f animals other ganisms to live.
The process of changing light into food oxygen is calledphotosynthesis. Besides light energy from the sun, plants also use water carbon dioxide. The water gets to the plant through its roots. The carbondioxide enters the leaves through tiny openings called stomata. The carbondioxide travels to chloplasts, special cells in the bodies of green plants.This is photosynthesis takes place. Chloplasts contain the chlophyllsthat give plants their green col. The chlophylls are the molecules thattrap light energy. The trapped light energy changes water carbon dioxide toproduce oxygen a simple sugar called glucose.
Carbon dioxide oxygen move into out of the stomata. Watervap also moves out of the stomata. Me than 90 percent of water a planttakes in through its roots escapes through the stomata. During the daytime, thestomata of most plants are open. This allows carbon dioxide to enter the leavesf photosynthesis. As night falls, carbon dioxide is not needed. The stomataof most plants close. Water loss stops.
If photosynthesis ceased, there would be little food other ganicmatter on the earth. Most ganisms would disappear. The earth’s atmospherewould no longer contain oxygen. Photosynthesis is essential f life on ourplanet.
