A（2019中考科普环保类选练）The world is not only hungry but also thirsty for water. This may seem strange to you, since nearly 70%of the earth's surface is covered with water. But about 97%of that is sea water or salt water. Man can only drink and use the other 3%of fresh water from rivers, lakes, underground and so on. And we can not even use all of that because some of it has been made dirty.Earth Day is April 22. But on all other days, we must also remember how important water is. The water that we use is the most important natural resource on the earth. Today we face serious water problems. One of them is water pollution. All kinds of things from cars, factories, farms and homes make our rivers, lakes and oceans dirty. Polluted water is very bad for people to drink. And dirty water is bad for fish, too.How do cars and factories make our water dirty? First they pollute the air. Then when it rains, the rain water makes our drinking water dirty. Dirty rain, called acid rain（酸雨）, is also bad for plants, animals and buildings. Scientists say that in 30 years, more than half of the people in the world won't have enough dean water. We have to learn how to stop wasting water. One of the first steps is to develop ways of reusing it. Today in most large cities, water i~ used only once and then sere out into a sewer system（下水道）. From there it returns to the sea or goes underground.But even though every large city reused its water, we would still not have enough. So we should make use of sea water by removing the salt in it. If we can take these steps, fresh water won't be used up.1. The world is thirsty for water because______.A．we don't have enough fresh waterB．a lot of water goes into sewer systemsC．only 70% of the earth's surface is waterD．sea water is widely used rather than fresh water2.

It seems that the stars are moving all the time. Actually, there is nothing wrong with your eyes. This twinkling effect is calledscintillation (交光). Scintillation happens because of air movements in the earth’s atmosphere (大气). Light is “bent (弯曲的)” when it travels through different parts of the earth’s atmosphere. As the air in the earth’s atmosphere is moving all the time, the light from the stars looks as if it is moving too.The same thing also happens to things on the ground. On a very hot and shiny day, if you look at the road, the image in the distance is not clear and things move slightly. You can also see the same effect if you drop a rock into water. The rock appears a little unclear under the moving water.This twinkling effect causes a lot of problems for astronomers (天文学家) since they cannot observe the stars clearly. A telescope (望远镜) was sent into space so that the air movements in the atmosphere could be avoided (避免). It took a long time to build the space telescope but finally in 1990, a huge space telescope called the Hubble Space Tele scope was successfully sent into space. Since then, astronomers have many important observations that have helped people understand space better. 根据短文内容，选择最佳选项。
