非谓语动词否定式的用法说明

不管非谓语动词是一般式,还是进行式,或是被动式、完成式,其否定式一律是在整个非谓语动词结构前加not或never。如:

Tony was very unhappy for not having been invited to the party. 托尼为没有被邀请参加那个晚会而感到很不高兴。

Not realizing that he was in great danger, Eric walked deeper into the forest. 艾瑞克没有意识到自己身处险境,他朝着森林深处越走越远。

Encourage your children to try new things, but try not to push them too hard. 鼓励孩子们尝试新的事物,但尽量不要给他们太大的压力。

Not having completed the programme, they have to stay there for another two weeks. 由于未完成计划,他们不得不在那里再呆两星期。

注意,对于in order to do sth和so as to do sth来说,其否定式通常是将否定词置于to之前(而不是整个短语之前),意思是“为了不……”“以免……”。如:

I shut the door quietly, so as not to wake the baby. 为了不惊醒宝宝,我轻轻地关上门。

Please reply at once in order not to lose this opportunity of a lower price. 请立即回复,以免失去这次低价的机会。

同时注意,如果不是表示“为了不……”,而是表示“不是为了……”,则用not in order to do sth。如:

One ship might fire a shot at another, not in order to hit it, but to warn it to move. 一只船可能向另一方鸣炮,不是为了击中目标,而是警告其快离开。
