Air is a colorless, tasteless and invisible（看不见的）gas that is around us. An “empty” drinking glass and an “empty” room, in fact, are not really empty. Each is filled with air. When the glass is filled with water, the water pushes the air out of the glass.
Air, as a gas, has no definite shape, but because it is matter, it takes up space and it has weight. It is easy to prove that air is something that takes up space. Stuff a piece of dry cloth（布）into the bottom of a glass so that it will not fall out when the glass is turned upside down. Push the upside down glass, holding straight up and down, into a jar of water till the glass is completely covered. When the glass is taken out of the water, the cloth is still dry. The air inside the glass shows that it takes up space and keeps the water from coming in.
1.Since air is matter, it has ________.
A．room , and weight as well B．both room and shape
C．either room or weight D．neither shape nor weight
2.The word “Stuff” means ______ in Chinese.
A．撕 B．盖 C．取掉 D．塞
3.The writer tells that the experiment（实验）___________.
A．is carried out in the space B．must be done in the lab
C．is made in the room D．can only be done in the open air

Maybe most people know that there is water pollution, air pollution and noise pollution around us, but few people know that there is another kind of pollution—light pollution. In fact, it can be everywhere, depending on the time of the day.
Light pollution is the result of the wasted energy. Instead of providing light for people on the earth, most bright light shines into the sky, because people don’t design lights very well. At the same time, lights are brighter than necessary. All these cause light pollution. Stars in the night sky always provide everyone with wonderful sights(景色), but light pollution prevents them from being seen.
Some scientists say that light pollution can also bring some health problems to people, especially to kids. So it’s the high time for us to do something useful to stop light pollution.
根据短文内容，判断下列句子的正(T)误(F)。
1.Light pollution isn’t serious enough for us to stop it now.
2.All the people know light pollution well today.
3.Most light shines into the sky instead of providing light for people.
4.People in big cities can’t see stars clearly in the night sky.
5.Light pollution doesn’t do harm to people’s health.
