Are the clothes yours or his?Jack: It’s not mine, it’s his.B. 作分析1. 形容词性物主代词相当于一个形容词，不能单独使用，只能用在名词之前作定语。

例如：We’re clean ing our TV room...2. 名词性物主代词相当于“形容词＋名词”，能单独使用，在句子中作主语、宾语、表语或者与of结构连用作后置定语。

例如：... they’re ours.各自特点1.在名词前已经有物主代词时，不能再用冠词及指示代词。

例如：We’re cleaning the our TV room...(?菖)We’re cleaning our TV room...(?菁)2. 形容词性物主代词可以与其它形容词一起修饰名词，但要放在其它形容词之前。

例如：This is my new radio.3. 名词性物主代词在句子中作主语时，谓语动词要和它所指代的名词的数保持一致。

例如：Her shoes are black. Yours are white.4. 汉语中经常省去“你的”、“我的”等物主代词，但在英语中不能省去物主代词。

例如：Jeff, put on your coat, please. 杰夫，请穿上大衣。

(汉语中省去了“你的”)5. its, his的形容词性物主代词和名词性物主代词是同形的，使用时要根据具体情况进行区分。

Its old meaning is used to express a temperatur e 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 show what he saw and felt.But the story also shows a scarcity (缺乏) of words. With out “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 ma y say, “It's cool.”A. interested inB. angry aboutC. afraid ofD. unhappy with4. The writer takes an example to show he is _________ the way the word is used.A. pleased withB. strange toC. worried aboutD. careful with5. In the passage, the writer suggests (暗示) that the word “cool”_________.A. can be used instead of many wordsB. usually means something interestingC. can make your life colourfulD. may not be as cool as it seemsBIf you do not use your arms or your legs for some time, they become weak; when you start using them again, they slowly become strong again. 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.2. If you don't use your arms or legs for some time, they will become strong.3. A good memory comes from more practice.4. Some people can't read or write, but they have better memories, because they have saved trouble.5. The best title of this passage is “How to Have a Good Memory”.CA meteorite (陨石) almost hit an 80-year-old man named Arthur Pettifer in Britain when he was working in his garden.
