动词不定式知识点: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,如果不定式较长,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,通常可以通过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,不定式后可以加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.

动词不定式知识点:不定式作宾语

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。

1、She considers it necessary to make friends with him.

2、We find it difficult to finish all the homework before 9 o’clock.

problem, purpose,thing,wish等名词为中心的短语,或以what 引导的名词性从句,不定式表语对主语起补充说明作用;例如:
