Working in these conditions is not a pleasure but a suffering.

在这种工作条件下工作不是一件愉快的事而是一件痛苦的事。

注意:动名词做主语时,谓语动词为单数

2)用 it 作形式主语,把动名词(真实主语)置于句尾作后置主语。

It is no use/no good crying over spilt milk. 覆水难收

It is a waste of time persuading such a person to join us. 劝说这样的人加入是浪费时间。

这种用法在习惯句型中常用,常用句型:

It is + no use/no good/useless/senseless/fun/enjoyable/tiring/interesting/foolish/nice/a waste of time/a pleasure... + v.ing

注意:important,essential,necessary 等形容词后面不用动名词(常用不定式)。

3) 用于"There be"结构中。

There is no saying when he'll come. 很难说他何时回来。

There is no joking about such matters. 对这种事情不是开玩笑。

常用句型:There is no + v.ing = It is impossible to do ...

注意:在"There be"句型中,只能用动名词,而不能用不定式作主语。

4) 用于布告形式的省略结构中。

No smoking ( =No smoking is allowed (here) ). 禁止吸烟。

No parking. 禁止停车。

5) 动名词的复合结构作主语

  当动名词有自己的逻辑主语时,常可以在前面加上一个物主代词或名词所有格,构成动名词的复合结构。动名词的复合结构也可以在句中作主语。例如:

Their coming to help was a great encouragement to us. 他们前来帮忙对我们来说是极大的鼓舞。

Lao Li's going there won't be of much help. 老李去不会有多大帮助。
