The word itself is becoming much smaller by using modern traffic and modern communication means(通訊設(shè)備). Life today is much easier than it was hundreds of years agobut it has brought new problems. One of the biggest problems is pollution(污染). To pollute means to make things dirty. Pollution comes in many ways. We see itsmell itsmell it, drink it and even hear it.

Man has been polluting the earth. The more peoplethe more pollution. Many years agothe problem was not so serious because there were not so many people.

Many countries are making rules to fight pollution. They stop people from burning coal()in houses and factories in the cityand from putting dirty smoke into the air. Pollution by so is now the most dangerous kind of air pollution. It is caused by heavy traffic. We are sure that if there are fewer people drivingthere will be less air pollution.

閱讀短文,根據(jù)短文內(nèi)容回答問題。(共10分,每小題2分)
  We need to be responsible for our environment. Being a frugal consumer(節(jié)儉的消費(fèi)者) is one way to help. But, what exactly does that mean?
  Use It Up
  You can use things up instead of wasting them. Squeeze that last bit of toothpaste out of the tube. Use the last little piece of soap. Don't throw away any bits of the biscuit at the bottom of the box.
  Wear It Out
  You do not always need to have new things. Suppose your sneakers have broken laces, but they still fit you. Repair them and wear them longer. You don't have the latest iPhone until the old one doesn't work anymore. Then you can get a new one. Think twice before replacing something that still works.
  Make It Do
  When something you want is not on hand, look for something else that you already have to take its place. Suppose you are packing your lunch for tomorrow and want a butter sandwich. You are out of butter. Have a cheese sandwich instead so that you can use all of the cheese. Learn to fix broken toys instead of just throwing them away. With a little thought, you can make something do, instead of buying something new.
  Do Without
  Think about all those things that you would like to have. Do you really need them? How long will you really play with that new toy you saw on TV? Making the things that we want uses up your world's resources(資源). And, getting rid of the things we don't want any more takes up even more resources and space.
 【小題1】Do we need to be responsible for our environment?
 【小題2】 How do we deal with the last little piece of soap?
 【小題3】When do we need to get a new iPhone?
 【小題4】 What should we do when something we want is not on hand?
【小題5】What does the writer want to tell us?

When the weather is hot, you go to a lake or an ocean. When you are nears lake or an ocean, you feel cool. Why? The sun makes the ear& hot, but it cannot make the water very hot. Although the air over the earth becomes hot, the air over the water keeps 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. When you are near a lake or an ocean, you feel the cool air. When it moves in, you feel the wind. And the wind makes you cool. Of course, scientists cannot answer all of our questions, ff you ask, "Why is the ocean full of salt?", scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks (裂開). 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. But then we ask, "What happens to the salt in the ocean?" The ocean does not get more salty every year. Scientists are not sure about the answer to the question. We know a lot about our world.
