不定式否定式的几点用法注意 ■ 定式的否定式的构成 不定式的否定式通常是将否定词not或never置于不定式之前,即构成not to do 或never to do 这样的形式。注意not和never一定要放在不定式符号to的前面,而不是其后面。如: He told me not to open the door. 他让我别开门。 Take care not to break the glass. 小心别把玻璃杯打碎了。 I told him not to make a mess in the kitchen. 我叫他不要把厨房弄得乱七八槽。 I promise never to smoke again. 我保证再也不抽烟了。 I’ll let you off if you promise never to do it again. 如果你答应以后再不这样做我可以放过你。 ■不定式否定式几点值得注意之处 1. 完成式的否定式:如果不定式为完成式,否定词应放在to have之前。如: She pretended not to have seen him. 她假装没看见他。 You were silly not to have locked your car. 你真笨,竟然没有把汽车锁好。 2. 被动式的否定式:如果不定式为被动式,否定词应放在to be之前。如: That’s not to be taken too seriously. 这不可看得太认真。 You were lucky not to be killed. 你大难不死,真是好运气。 3. so as to的否定式:如果不定式为so as to或in order to的被动式,则否定词应放在to 之前,而不是放在so as to或in order to整个结构之前。如: I’m going to leave now, so as not to be late. 我要走了,免得迟到。 I arrived early so as not to miss anything. 我到得很早,以免错过什么。 Please reply at once in order not tolose this opportunity of a lower price. 请立即回复,以免失去这次低价的机会。 |
