1、非谓语动词 在句子中充当除谓语以外的句子成分的动词形式叫做非谓语动词 。非谓语动词分为三种形式:不定式,动名词,和分词(分词包括 现在分词和过去分词)。1)不定式 时态语态 主动 被动 一般式 to do to be done完成式 to have done to have been done2)动名词 时态语态 主动 被动 一般式 doing being done完成式 having done having been done3)分词 时态语态 主动 被动 一般式 doing being done完成式 having done having been done 否定形式: not +不定式,

2、not/no + 动名词, not + 现在分词动词不定式 1)作主语: To finish the work in ten minutes is very hard. To lose your heart means failure. 动词不定式短语作主语时,常用it作形式主 语,真正的主语不定式置于句后,例如上 面两句可用如下形式: It is very hard to finish the work in ten minutes. It means failure to lose your heart. 动词不定式 2)作表语: Her job is to clean the hall.

3、 He appears to have caught a cold. 5)作定语: 动词不定式作定语,放在所修饰的名词或代词后。 与所修饰名词有如下关系: 动宾关系: I have a meeting to attend. 注意:不定式为不及物动词时,所修饰的名词如果是 地点、工具等,应有必要的介词,如: He found a good house to live in. The child has nothing to worry about. 如果不定式修饰time, place, way,可以省略介词: He has no place to live. This is the best

4、way to work out this problem. 说明所修饰名词的内容: We have made a plan to finish the work. 序数词和最高级后用不定式做定语: He is the first to get here. 动词不定式 做状语 表目的: He worked day and night to get the money. She sold her hair to buy the watch chain. 表结果: He arrived late to find the train gone. 常用only放在不定式前表示强调: I visited

7、逻辑主语 须和句子的真正主语一致。若不一致,则 须加上自己的逻辑主语1. _no buses , we have to walk home 2. _Sunday, I shall have a quiet day at home .A.There being B. It were C. There were D.
