比如：join, be used to do, thanks to, abroad, spe 重点知识讲解1. Today they are talking about buying a new computer. 今天他们谈论买一个计这里的talk about的意思是“谈论；谈及到；讨论”，后面通常加上名词或动名词。
We talked about it yesterday.I want to talk about the price of the car with you.2. Did you find out the price for the IBM PC 486? 你找出IBM PC 486的价这里的词组find out和find都是表示“找出”，都是一个结果。
但是两种也有区别：如果表示I found this wallet outside the classroom.What did you find just now?如果要表示经过一番努力或研究得出的结果的时候，find和find out都可以，但通常用后者。
I finally found out the secret of his death.She wanted to find out the real answer to the question.3. I’ve高中一年级英语教案Computernbsp;game.They lost the game thanks to the foolish advice you gave them.10. At one time, there were long queues of people waiting outside the CA 队列。
词组at one time表示的意思是“以前；曾经”。
比如：At one time we met each other every day.He went to that restaurant to have dinner at one time.11. These people will be welcome on our planes. 我们欢迎这些人来乘坐我们的飞这里的welcome在这句话中是一个形容词，表示的意思是“受欢迎的”，后面常加的是不定式。
比You are welcome to do anything you like.Welcome to Beijing.welcome这个词也可以是名词。
比如：They received a cold welcome when they arrived.同样welcome也可以作为一个及物动词，但后面不加不定式，而且过去式和过去分词都是welcom All the students welcomed the visiting friends at the school gate.12. In my opinion, we should buy the IBM PC 586. 依我看来，我们应该买IBM 这里的情态动词should表示的意思是“应该”，通常用在表示建议的句子中。
比如：I should go home before 6 o’clock.You should not ask others to do your homework.13. If we buy the smaller one, the IBM PC 486, we might have to change 们现在要是买了IBM PC 486，几年以后我们肯定要换一个更大的计算机。
这里的if是一个条件句。
后面出现的两个逗号之间的东西从位置上说是一个插入语，从成份上来们通常用一个名词性短语或从句来作为同位语14. I don’t think I it’s necessary to buy the bigger one.我想没必要买较大我们通常在think, suppose, expect, imagine等表示心理活动的动词后面不加否定含义的宾否定是转移到主句的谓语动词之前。
比如：I don’t think I can get away at the moment.I don’t suppose you need to worry.I don’t think I know you.15. The IBM PC 486 will be big enough for us. IBM PC 486对我们来说就够大句子中的enough可以是形容词，也可以是副词。
通常我们将enough放在名词前面或形容词或副词I don’t have enough money to buy a house.I am not rich enough to buy a house.16. We mustn’t waste any more time. 我们不可以在浪费更多的时间了。
这里的情态动词mustn’t表示的不是“必须不”而是“不可以；不允许”。
通常用在命令的句子You mustn’t talk in class. It is not a good habit.We mustn’t go there&n高中一年级英语教案Computerbsp;because it is dangerous.17. We must decide which one to buy. 我们必须决定买哪一个。
这里的which one to buy为特殊不定式短语，在句子中做decide的宾语。
特殊不定式的构成what, which, who, whether等；常用的关系副词有how, when, where, why等。
比如：We haven’t decided what to do next.I don’t know how to write in English.I will ask when to start tomorrow morning.She will ask where to live.18. At one time, there were long queues of people waiting outside the CA 队列。
这里的waiting是一个现在分词，在句子中做people的定语，放在名词后，相当于一个定语从句The foreigner talking with our teacher is head of the visiting group.The man running after the bus is a friend of mine.19. As a result, the number of people who travel by plane in China is 往多了。
这句话中的as a result的作用相当于一个副词，意思相当于so。
比如：He hurt himself. As a result, he couldn’t go to school.这句话中的the number of 的中心词是number，说明谓语动词肯定是单数的。
比如：The number of the books in this bookshop is more than 200,000.20. 我们在很多句子中都用一个代词来代替前面提到的名词，常见的有one, it和that。
这三1, one=a/an +noun 所代表的是前面提到的同类中的任何一个He has no book and no money to buy one.The hat is too small. Please show me a larger one.2, it= the/this/that/adj.+ noun 指同一件事物He has a book, but he will not lend it to me.I drank some iced water, but it made me more thirsty.3, that = the + noun 指前面所提到的同一类中的另外制定的一个.The air of the country is purer than that of the city.比较下面三句话：I cannot find my umbrella; I think I must buy one.I cannot find umbrella; I don’t know where I put it.The umbrella you bought is cheaper than that I bought.高中一年级英语教案Com 高中一年级英语教案Computer;got the information for all the computers now. 我已经得到了所有计算机的信息了这里的information同news一样是一个不可数名词。
