8. Now it is possible to find out much faster which planes are full. 现在要找到哪架飞机满了比以前要快多了。 这里用了一个much表示一个程度。通常在much, even和still后面加上一个形容词或副词的比较级形式。比如： I am much heavier than before. She is much happier than she was two years ago. 9. Thanks to the new computer, the passengers at the offices of the CAAC can now buy their aeroplane tickets much faster. 由于使用了新的计算机，乘客在中国民航购票快多了。 句子中的thanks to是一个常见的短语，表示“由于;幸亏”，相当于because of, 或者as a result of表示原因。比如： Thanks to your help, I was able to win the 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 CAAC offices. 以前，中国民航办公室前等着购票的人们排成长长的队列。 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机。 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。比如： 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welcomed。比如： 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 PC 586。 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 it in a few years’ time for a bigger one. 如果我们现在要是买了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，从成份上来说是一个同位语，是对前面的名词the smaller one进行解释。我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.我想没必要买较大的那个。 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语从句。如果后面的从句使一个否定句，我们常常将从句谓语动词的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对我们来说就够大的了。 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的后面。而且通常在后面再加上不定式。比如： 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中。比如： You mustn’t talk in class. It is not a good habit. We mustn’t go there 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。特殊不定式的构成形式为“关系代词或关系副词+动词不定式”。常用的关系代词有：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. (责任编辑：admin) |
