动词不定式讲解,专项练习及答案
初中英语语法（动词不定式）1．不定式的基本形式与结构动词不定式指通常由to加上动词原形(如to write) 所构成的一种非限定性动词形式，但在有些情况下to能够省略。
动词不定式有实行体和完成体(如上to be writing，to have written)，也有被动态(如to be written)，所有的主动词，不管是及物动词还是不及物动词，也不管是动作动词还是状态动词，都有不定式形式。
助动词除be和have外，没有不定式形式。
动词不定式在语法功能上可作主语、宾语、表语、定语和状语。
2．不定式的用法1)不定式结构作主语1.Te get contact with his family in Taiwan made him extremely happy since they separated more than 40 years ago．2.To finish that task in such a short time is really a challenge．在上述情况下，假如不定式较长，显得头重脚轻，则可由代词让作形式主语(形式主语it不可由that或this等其他代词代替)，而将不定式放到后面。
如：1.It made him extremely happy to get contact with his family in Taiwan since they separated more than 40 years ago．2.John admitted that it is always difficult for him to be on time．不定式结构所表示的动作是谁做的，即不定式的逻辑主语，通常能够通过for sb. to do sth. 结构表达：1.It is quite important for us to read good books during a general review．2.It is not difficult fot those talented students to pass the exam.在某些形容词(如careless，clever，considerate，foolish，good，impolite，kind，naughty，nice，silly，stupid等)作表语时，不定式后能够加of来引导出其逻辑主语：1.It is very kind of you to tell me the truth．2.It is stupid of him to do such a silly thing．2)不定式作宾语不定式作宾语有两种：一种是及物动词后直接跟带to的不定式，另一种是“及物动词+疑问词+带to的不定式。

另外，动词不定式具有动词特点，可以有自己的宾语和状语，组成动词不定式短语。
动词不定式的肯定形式是to＋do；其否定形式是not to＋do。

如果其后接形容词补足语时，则可以用it作形式宾语，而把作真正宾语的不定式放到后面Sb + V + it （形式宾语）+ agj （形容词）+to+ V（宾语）注意无BE动词。
(三)、动词不定式作宾语补足语Mr Li often teaches his Japanese friends to cook Chinese food.He found it very difficult to learn English well.不定式可以用作宾语补足语。
