动词­ing 形式的被动式

当动词­ing形式的逻辑主语是动作的承受者时，要用其被动形式，即being done，它表示一个正在进行或与谓语表示的动作同时发生的被动动作。与其主动形式一样，它在句中可充当主语、宾语、定语、补语、状语。

1．作主语

being done用于句首作主语，表示一个被动的动作。

①Being exposed to sunshine for too much time will do harm to one's skin.

在阳光下暴露太久对皮肤有害。

2．作宾语

being done 可以用于动词或介词后作宾语，表示一个被动的动作。

②The film star wears sunglasses. Therefore, he can go shopping without being recognized.

这个影星戴着墨镜，所以他能在购物时不被认出来。

3．作定语

being done 作定语，只能置于被修饰的名词后，表示一个正在进行的被动动作。

③The problem being discussed now is very important.

现在正在被讨论的这个问题非常重要。

4．作补足语

being done 可以用在某些动词(see, hear, watch, feel, notice, find, keep ...)后作宾语补足语，表示一个正在进行的被动动作。

④You'll find the topic being discussed everywhere now.

你将发现这个话题现在到处被讨论。

5．作状语

being done用作状语，是一个比较重要的用法，主要用于句首表示原因，有时也表示其他关系(如时间等)。

⑤Being repaired, the road is blocked now.

因为这条路正在被修建，所以被堵上了。

being done的完成式为“having been done”，说明它所表示的动作在谓语动作之前发生，通常在句中作宾语和状语。

⑥Having been taught many times, the boy still couldn't finish those tasks independently.

已经被教了许多次，这个男孩仍然不能独立完成这些任务。

being done的否定形式为“not being done”；其完成式的否定形式为“not having been done”。

⑦He was unhappy for not being invited to the party.

对于没有被邀请去参加宴会，他感到不高兴。
