考点解读
考点1 连接词that与whether/if
一、连接词 that的用法
1.that在名词性从句中不作任何句子成分,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。
I love the fact that Chinese buses,motorcycles,trains and aircraft are either economical or cheap.
我喜欢中国的公共汽车、摩托车、火车和飞机,既经济又便宜。
【点津】that引导宾语从句时几种不能省略的情况:
①that从句作介词的宾语时;②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;③宾语从句前有插入语时;④that引导的宾语从句位于句首时。
2.that引导主语从句时,用it作形式主语的常用句型
(1)It+be+形容词(necessary,right,likely,unlikely,wrong,important,certain等) +that从句
It is unlikely that I should accept such an offer as that.
我不可能接受那样的提议。
(2)It+be+名词(短语)(a pity,a shame,a surprise,no wonder等)+that从句
It is a pity that your composition has so many spelling mistakes.
很可惜,你的作文有这么多的拼写错误。
(3)It+be+过去分词(said,reported,decided等)+that从句
It is decided that the meeting has been put off till next Monday.
已决定会议推迟到下周一举行。
(4)It+特殊动词(短语)(seems,appears,happens,matters,turns out,makes no difference 等)+that从句
It turns out that the brain needs exercise in much the same way our muscles do.
结果表明,大脑像肌肉一样都需要锻炼。
【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。
①It is a pity+that...
②It is necessary/strange/important/natural...+that...
③It is suggested/requested/required/proposed/desired...+that...
3.it作形式宾语的宾语从句
(1)find,feel,think,consider,make,believe等的宾语后有宾语补足语时,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.
他清楚地表明会议不会被推迟。
(2)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.
你不在的时候,我保证照顾好他。
二、连接词 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。
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:
①后面直接跟or not时;
②用于介词后引导宾语从句时。
【点津】doubt后接从句时,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that。
The doctor really doubts whether/if my mother will recover from the serious disease soon.
医生真的怀疑我母亲是否能很快从重病中康复。

我们的老师总是告诉我们,如果我们想要成功,要相信我们所做的事情和我们自己。
二、 whatever,whoever,whomever,whichever与 what,who,whom,which的区别

whom 在名词性从句中作宾语,意为“谁”
whichever 意为“无论哪个/哪些”,表示有范围的选择,在名词性从句中作主语、宾语或定语
