I. Reading comprehension (阅读理解）
A. Choose the best answer (根据短文内容，选择最恰当的答案）：（共6分）
When the weather is hot, you go to a lake or an ocean. When you are near a lake or an
Ocean, you feel cool. Why? The sun makes the earth hot, but it cannot make the water very hot. Although the air over the earth becomes hot, the air over the water is still cool. The hot air over the earth goes up. Then the cool air over the water moves in and takes the place of the hot air.
Then you may ask, “Why is the ocean full of salt?” Scientists will say that the salt comes from the rocks. When the rocks get very hot or very cold，they crack (爆裂）.Rain falls into the cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean.

Water is very important for living things. Without water there can be no 1 1 on earth. All animals and plants need water. Man also needs water. Water is found a 2 everywhere. Even in the d 3 part of the world there is some water in the air.
As we all have found out, water may be a solid, or a 1 4 or a gas. When it is a solid, it may be as hard as a brick. When it is a liquid, you can pour it out of a c 5 .

D. Answer the questions (根据短文内容回答下列问题）：（共6分）
In the time it takes you to read this sentence, the population of the Earth will have grown by 10 people. That may not sound much, but it is about 14,000 people an hour. That is the same as adding most of the population of Germany to the world every year!
Most of these new people are born in developing countries. These countries are found in much of Africa, South America, and parts of Asia. In the developed countries of Europe and North America, the population is growing very slowly. This is because women in these countries have, on average, only one or two children. In the developing countries, many women have five or more children. In 1950, around one quarter of the world’s population lived in the developed countries. By 2050, these countries will be the home to only around one tenth of the world’s people.
In the developing countries，more than one billion people already live below the poverty line(贫困线）.These people don’t have enough food to eat and they live in poor housing； children get little or no time at school and suffer from many kinds of diseases.
The United Nations(UN) tries to guess population growth. At the beginning of the 21st century, the world's population was around six billion people. The UN has said that the world's population will level off at 12. 5 billion people by the year 2100. Other people think the world's population will continue to grow, reaching 14 billion people before it becomes stable or even falls.
1. How many people are added to the world’s population an hour?
2. In what areas of the world can developing countries be found?
3. In 1950，what percentage of the worlds population lived in developing countries?
4. By 2050，there will be many more people living in the developed countries, won’t there?
5. How many people will there be in 2100 according to the UN?
6. What may happen if the population keeps growing?

Save water
Water is very important to all of us. Without water, there would be no life on the earth.
It’s a pity that there are many people who often waste water. For example，some people don’t turn off the tap after they finish using it. Some people throw away their bottles with water in them.
I think we should try our best to save water. We should turn off the tap when we don,t use it. When we take a shower, we should be quick.
