如题所述
非谓语动词作表语。共三种情况：1。动词不定式：To live is to study.(活到老学到老.)英语中常出现这种对称现象,即主语是不定式,表语也是不定式.2.动名词:My job is teaching you English.(我的工作是教你们英语)这里动名词来叙述内容的.3.分词(现在分词和过去分词)现在分词作表语:My job is very interesting.(我的工作很有趣)这里的现在分词是描述性状特征的.表示主动,过去分词作表语:I am interested in English.(我对英语感兴趣)这里用过去分词表明,客观事物使得人发生了兴趣.含有被动的意念..但主语是人的时候,常用过去分词作表语.尤其是那些使动词.但主语是事物时,用现在分词作表语,强调事物本身具有的特征.

做表语的非谓语动词的选择
表语的考查多侧重于分词做表语形式的选择，很少有动名词的用法的考查，虽然选项中有不定式作为干扰项，只要能看出是做表语的也就不用考虑。如：
① The house was very quiet, ____ as it was on the side of the
mountain.(1999.6)
A. isolated B. isolating
C. being isolated D. having been isolated
② These surveys indicate that many crimes go _____ by the police,mainly becausenot all victims report them.(2000.6)
A. unrecorded B. to be unrecorded
C. unrecording D. to have been unrecorded
分词做表语可以做系动词be的表语，也可以做其它系动词的表语，如go, feel,seem, look, remain等等。这些系动词后非谓语动词的用法规则是相同的。
3.不定式常表示一次性具体的行为,动名词表经常性习惯性的行为,v+ing表示主语的性质特征.
He likes to go for a walk this evening .今晚
He likes having a walk every day after supper.每天
The film is interesting.电影的性质特征,一般不用人做主语.本回答被网友采纳
