虚拟语气在as if / as though 引导的方式状语从句中的应用(谓语动词形式与wish后的宾语从句基本相同)

  (一) 表示与现在事实相反或对现在情况有怀疑,谓语动词用过去式。例如:

  ① He felt as if he alone were responsible for what had happened. 他感到仿佛唯独他要对发生的一切负责。

  ② He acts as if he were / was a TV expert. 他做起事来好象是个电视专家。

  (二) 表示过去想象中的动作或情况,谓语动词用过去完成式。 例:

  The tree looked as if it ______ for a long time.

  A. hasn't watered B. didn't water C. hadn't bee watered D. wasn't watered

  那棵树看上去好象很久没人给浇水了。(答案是c)

  在lest 引导的状语从句中,谓语动词多用虚拟语气,(should )+ 动词原形。例如:

  The mad man was put in the soft-padded cell lest he _____ himself.

  a. injure b. injured c. had injure d. would injure

  这个疯子被关进墙上装有衬垫的病房,以免伤了他自己。(答案是a)

  在if only 引起的感叹句中需用虚拟语气。谓语动词用过去式或过去完成式。 例:

  Look at the terrible situation I am in! if only I ____ your advice.

  A. follow B. had followed C. would follow D. have followed

  if only 引出感叹句,意思是“要是……多好”,表示说话人的一种愿望,希望发生(事实上不可能发生)与过去事实相反的情况。本句的全句意思是:“看我现在的处境多糟糕!要是我听从你的劝告多好”。事实上,句中的“我”没有听从劝告,所以处境很糟糕。 题中空格处应当用虚拟语气,答案是B。
