閱讀理解(一)The population of the earth is growing faster. Its important that we look after the earth. We need it! The earth gives us a lot of things. We also give the earth a lot, but some of the things are not good.In nature, when something dies, other animals and plants get food from it. Every animal or plant gives food to other animals or plants. However, animals cant get food from many of the things that we give the earth. Animals and plants cant eat metal, plastic and glass. These things will stay in the ground for many, many, many years.Some rubbish is very dangerous for plants and animals. In some places, many animals live together. One animal makes food for many more animals. If we put rubbish and chemicals in the water, the plankton(浮游生物) die. If there isnt any plankton, many animals have nothing to eat.So what can we do? Dont leave any rubbish in the countryside! Dont make so much rubbish! 閱讀理解(二) Many textbooks are not written in the kind of English that we speak every day. In fact, sometimes the reading is so difficult that it almost seems like a foreign language. In a way, it is-the language of science. You should not expect to be able to read a difficult science passage the same way you read an interesting story; you should not expect to read it easily and all at once. Instead, you may have to read it several times through, catching on the meaning of difficult words, going back over difficult sentences, and finally putting the whole thing together. Do not be discouraged if the whole passage doesnt make sense to you at first. You need to pick it apart patiently until you can understand it. These are the steps to follow when you are reading something difficult:1. Start to read normally until you run into a sentence that doesnt make sense to you.2. When a sentence doesnt make sense, go back and read it again more slowly.3. Look for any words you dont know in the sentence. Try to understand their meanings using word parts and context clues. If necessary, look them up in the dictionary.4. Look at the next few sentences to see if they explain more about the sentence you are working on. Do not read very much farther ahead until you understand what is being said.5. Finally, read the sentence again. Try to put it into simpler words.6. Read through the passage once. Try to understand all the hard parts well. Then read the whole passage once more at a usual speed. This helps you to put all ideas together.The steps sound a lot harder than they are. It is really just the normal way good readers understand anything that is difficult to read. After you have done the best you can this way, you should always feel free to ask for help from your teacher, if you have one.
