阅读理解。    Trees are useful to man in three important ways: they give him wood and other useful things, they give him
cool places, and they help to stop drought and flood.
   Unluckily, in many parts of the world, man has not found that the third of these points is the most important.
Man wants to make money from trees,so he has cut them down in large numbers, only to find that without
them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees.
So the forests slowly disappear.
    This does not only mean that man will have fewer trees. The results are even worse: for where there are
trees, their roots break up soil-make the rain in-and also bind the soil, thus stopping it from being washed away
easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying
away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert. 1. The most important points of trees to man is _____. [     ]
A. they help him to make money
B. they give him cool
C. they give him wood and other things
D. they help him to stop drought and floods 2. In many places forests slowly disappear because _____. [     ]
A. many trees have been cut down by man
B. new trees are not well looked after
C. man has not paid enough attention to planting trees
D. all the above 3. Land becomes desert after all trees are cut down because _____. [     ]
A. roots of trees break up the soil
B. there are too many rainfalls
C. strong winds bring a lot of sand
D. there are no longer trees to keep the rain and protect the top-soil. 4. Which title best fits the passage? [     ]
A. Trees and Man B.The Function of Tree Wood
C. How do People deal with Trees?
D. The Usage of Tree Roots

He said the WHO is also watching on similar evidence in the UK, Spain, Japan and Chile.
    In Hong Kong, the government on Thursday ordered the nurseries, kindergartens and primary schools to

Millions of years ago there were many types of dinosaurs on earth. Most dinosaurs were plant-eaters. The Apatosaurus, for example, had a long thin neck so that it could eat leaves from trees. Other dinosaurs were meat-eaters. The Tyrannosaurus Rex killed smaller dinosaurs for food. Dinosaurs were real animals that once lived on the earth, but they died out about 65 million years ago. The disappearance of the dinosaurs is in some way a great mystery (谜). Some scientists think that the climate (气候) changed suddenly. Fossils (化石) of trees tell us that the temperature dropped a lot and that the level of the sea dropped as well. This means that it got suddenly much colder. Perhaps the dinosaurs were too slow to change with the climate. A new idea is that a meteor (流星) crashed into the earth. Scientists discovered a place in Mexico where they think the meteor crashed. They think that there was a lot of dust from the meteor. The dust landed on the plants.Also the dust blocked (阻挡) the sun"s light for as long as five years. Many animals, including dinosaurs, were plant-eaters, and perhaps the dust killed them. This means there was nothing left for meat- eating dinosaurs to eat, and so they died out. But, as many animals from that time didn"t die, we are not 100% sure what really happened.
1. What is the subject discussed in the text?
[ ]
A. Dinosaurs, the real animals living millions of years ago. B. The two types of dinosaurs. C. The probable reasons for dinosaurs disappearance. D. A meteor crashed into the earth.
2. What are the two possible explanations to the dinosaurs disappearance?
[ ]
A. Temperature dropping and sea level dropping. B. Climate changing and meteor"s crashing. C. The dropping of temperature and sea level. D. Climate changing and the dust blocking the sun.
3. What is the direct cause of the disappearance of meat-eating dinosaurs?
[ ]
A. A meteor"s crashing. B. The dust blocking the sun. C. The plant-eating dinosaurs death. D. It is still unknown.

Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the world forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger. Why should people care? Because we need animals. And because once they are gone, there will never be any more. Animals are more than just beautiful and interesting. They are more than just a source of food. Every animal has its place in the balance of nature (生态平衡). Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks (老鹰), the farmers stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiplied (繁殖) quickly. Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid (禁止) the killing of any animals or plants on the danger list. Slowly, the number of some animals in danger is growing.

[ ]
A. People care much about animals because they need them. B. Once a certain kind of animals is gone forever, there will never be any more. C. Killing all rats and mice may cause some problems. D. People must not kill any animals.
