动名词作表语,关于非谓语动词作表语的问题

   此处有解释

另外:

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。如动名词作表语：

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。
