九、名词性从句考点1连接词1. that(1)that在名词性从句中不作任何成分, 引导宾语从句时有时可以省略, 引导主语从句、表语从句和同位语从句时不能省略We must not forget that housing is for living, not for speculation. *I love the fact that Chinese buses, motorcycles, trains and aircraft are either economical or cheap. 【点津】that引导宾语从句四种不能省略的情况: that从句作介词的宾语时*I dont know exactly where he lives, except that its somewhere out in the wilds. 动词后跟有多个that引导的宾语从句时, 只有第一个that可以省略, 从第二个从句开始that不可省略He told me he had to leave and that he would be back soon. 宾语从句前有插入语时*We hope, on the contrary, that he will stay at home with us. that引导的从句位于句首时*That you dont like him is none of my business. (2)that引导主语从句时, 常用it作形式主语的常见句型有: It+be+形容词(necessary/right/likely/unlikely/wrong/important/certain等)+that从句*It isnt likely that I should accept such an offer as that. It+be+名词(短语)(a pity/a shame/a surprise/no wonder等)+that从句*Its no wonder that he didnt want to go. It+be+过去分词(said/told/reported/decided等)+that从句*It is decided that the meeting has been put off till next Monday. It+特殊动词(seems/appears/happens/matters/turns out/occurs to/makes no difference etc. )+that从句*It suddenly occurred to her that Joe was afraid of being alone. 【点津】在以下主语从句中, 常使用虚拟语气, 即谓语动词用“should+动词原形”形式, 其中的should可以省略。

It is necessary/strange/important/natural etc. +that. . . It is a pity that. . . It is suggested/requested/required/proposed/desired etc. +that. . . *Its necessary that a college student (should) master one or two foreign languages. (3)it作形式宾语的宾语从句动词find, feel, think, consider, make, believe等后面有宾语补足语时, 需用it作形式宾语而将that引导的宾语从句后置He has made it clear that the meeting will not be postponed. 一些动词短语see to, depend on, rely on等常用it作形式宾语, 而将宾语从句后置I shall see to it that he is taken good care of when you are absent. 2. whether与if引导的名词性从句(1)引导主语从句、表语从句、同位语从句时一般用whether, 不用if。

Whether he can finish his task on time is of great importance. *The problem is whether the air pollution can be controlled. (2)whether与if引导宾语从句时大多数情况下可以互换, 但下列情况下宜用whether: 后面直接跟or not时用whether*I dont know whether or not the report is true. 用于介词后引导宾语从句时用whether*It depends on whether we have enough time. 【点津】doubt后接宾语从句时, 如果用于肯定句, 从句的引导词用whether或if; 用于否定句或疑问句时, 从句的引导词常用thatThe doctor really doubts whether my mother will recover from the serious disease soon. *Never once did I doubt that I would be able to carry out my plan. 【题组训练】1.
