Its old meaning is used to express a temperature that is a little bit cold. As the world has changed, the word has had many different meanings.“Cool”can be used to express feelings of interest in almost anything. When you see a famous car in the street, maybe you will say “It's cool.”You may think, “He's so cool,” when you see your favourite footballer.We all maximize (扩大) the meaning of “cool”. You can use it instead of many words such as “new”or “surprising”. Here's an interesting story we can use to show the way the word is used. A teacher asked her students to write about the waterfall (瀑布) they had visited. On one student's paper was just the one sentence, “It's so cool”. Maybe he thought it was the best way to showwhat he saw and felt.But the story also shows a scarcity (缺乏) of words. Without “cool”, some people have no words to show the same meaning. So it is quite important to keep some credibility (可信性). Can you think of many other words that make your life as colourful as the word “cool”? I can. And I think they are also very cool. 1. We know that the word “cool” has ________.A. only one meaningB. no meaningsC. many different meaningsD. the same meaning2. In the passage, the word “express”means“________”.A. seeB. showC. knowD. feel3. If you are ________ something, you may say, “It's cool.”A. interested inB. angry aboutC. afraid ofD. unhappy with4.

Everybody knows that. Yet many people do not seem to know that memory works in the same way.When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong.If a friend says that his arms and legs are weak, we know that it is his own fault. But if he tells us that he has a poor memory, many of us think that his parents are to blame, and few of us know that it is just his own fault.Have you ever found that some people can' t read or write but usually they have better memories? This is because they cannot read or write and they have to remember things; they cannot write them down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised.So if you want to have a good memory, learn from the people: practise remembering.1. The main reason for one's poor memory is that his parents have poor memories. T F2. If you don't use your arms or legs for some time, they will become strong. T F3. A good memory comes from more practice. T F4. Some people can't read or write, but they have better memories, because they have saved trouble. T F5. The best title of this passage is “How to Have a Good Memory”.参考答案： 1. F 2. F 3. T 4. F 5.

The one time I wasn’t sure of that was on September 11.I usually wake up a 6:30 or 7:00 in the morning. That day, I happened to wake up earlier. I turned on the TV and I saw that a plane had crashed (撞击) into the North Tower of the World Trade Center. My first reaction (反应) was that it was a terrible accident. Then I saw another plane fly into the South Tower and I realized that I was witnessing (目击) an act of terrorism.My wife and I spent the day watching the terrible pictures over again. When I watched family members looking for their loved ones, the pain in their eyes w as something I would never forget. I couldn’t understand how something this terrible could have happened.It wasn’t until a few weeks after September 11 that I began to see that perhaps some good did come from this tragedy (悲剧). People seem different now, more understanding, more tolerant(宽容的). Little things that seemed to be such a trouble before are no longer big things. Personally, I am more tolerant than I was. I realize life is too short, andtoo precious(珍贵的), to let myself get worried over small th ings. I’ve learned also that you can’t take things for granted. Things change in the blink of an eye. People go to work and don’t come back. One moment they’re living and the next minute they’re not. And, it doesn’t matter who you are, there is nothing you can do about it. We never know when our time here will be over, so we all need to make the most of every minute we have.You try to learn from what happened. You can’t be used up by it. You can’t live by it. All you can do is just live.1. The word “positive” in the passage probably means ______.A. terribleB. badC. goodD. real2. What did the writer see after he turned on the TV that morning?A. A fire startingB. A plane flyingC. A terrible accidentD. An act of terrorism.3. From September 11, the writer had realized that___________.A. people should make the most of every minute they haveB. he has become less tolerant towards othersC. he should get worried about little thingsD. life is too short to care about others.4. What’s the best title of this passage?A. A Report about September 11B. The Tragedy ofSeptember 11 C. September 11 and My Family D. September 11 and My Turn.阅读理解阅读下列短文，并根据短文内容选出能完成短文题目的最佳答案。
