表语从句对主句主语进行说明、解释,使主语的内容具体化。

表语从句什么是表语?表语从句,紧跟着系动词的从句其中,am,look,seem 都是系动词。
而系动词后面的东西,就是表语。
换句话说,表语从句就是紧跟着系动词的从句。
6类系动词在正式讲表语从句以前,先简单盘点下常见的6类系动词:表语从句3大类型01 系动词+ that02 系动词+ 疑问词03 系动词+ 特殊连接词that 仅仅只是连接词,什么成分都不是。
在口语和非正式文体中,that 有时是会省略的;很多语法讲解文章称“that 不能省略”,这个规定就太死了。
比如,值得注意的是,如果整句的主语是要求、建议、命令等词,表语从句用“should + 动词原形”;其中,should 可以省略。
系动词+ 疑问词不少语法讲解文章、视频都喜欢把疑问词再细分为疑问代词、疑问副词,这会增加理解的负担,所以我把各种疑问词归为一个大类来讲。
这里,用“非常6+1”来记:5W1H:what,when,where,who,why,how 再加1个:whether很多同学会混淆why 和because 的用法,这里顺带提一下。
二者的相同点:均可用于This/ That/ It is...句式。
不同点则在于——来看2个例子。
That is why I hate to go to the dinner party.那就是我打死不想去赴宴的原因。
单从这句话来看,我们只知道一个信息:我打死都不想去赴宴——这是结果。
原因呢?并没有说。
而——That is because she is a terrible cook.那是因为她做饭巨难吃。
“她做饭很难吃”,这个才是原因。
以上归纳起来就是:This/ That/ It is Why + 结果This/ That/ It is because + 原因The reason is that + 原因系动词+ 特殊连接词1. (just) as “正如”常跟look,seem,appear等系动词连用以上归纳起来就是:This/ That/ It is Why + 结果This/ That/ It is because + 原因The reason is that + 原因系动词+ 特殊连接词1. (just) as “正如”常跟look,seem,appear等系动词连用2. as if,as though “好像”也常跟look,seem,appear等系动词连用这里分2种情况:1)如果是有可能发生的事情,用正常的时态;2)如果是跟事实相反的情况,用虚拟语气(往前退一个时态);这个知识点跟以前讲过的虚拟语气有联系,建议抽时间回顾一下虚拟语气攻略一:跟事实相反的3类if从句△虽然她们的房间忒乱,但仍不是现实意义上的猪窝;加上说话者在讲过去发生的事情,推断——跟过去事实相反,从句(往前退一个时态)用过去完成时。
