豌豆语法——表语从句

豌豆群：7298916一、表语从句定义：在一个复合句中，从句作的是主语的表语成分。四、引导词的用法3whether在表语从句中表是否,但不充当句子的成分。if不能引导表语从句.如:
①.Whatthedoctorreallydoubtsiswhethermymotherwillrecoverfromtheseriousdiseasesoon.
②.Thequestioniswhetheritisworthdoing.
4who在表语从句中充当______________表示____.
①Theproblemiswhocoulddothework
②Mytroubleiswho(whom)Icanturnto.
5which在引导表语从句时,常充当_定语、表语
表示哪一个。如：
Ireadaboutitinsomebookoranother,butwhatIdon’tknowiswhich(book)itis.

五、注意3当主句的主语为reason,或者是由why引导的从句时,与它们相关的表语从句用that而不能由because引导;because引导表语从句时只能用于It/That/Thisis/wasbecause…句型中.
①.ThereasonwhyIwaslatewasthatImissedthetrain.
②.Iwaslate.It/That/ThiswasbecauseImissedthetrain.
4当表语从句中主语、宾语、表语具备，但是还是要表示疑问含义，可以判断句子中缺少状语，常常用相应的特殊疑问词引导，有why,when,where,how等
Thisishowhedidit.
Thatiswhythebrotherswantedtomakeabet.
That’swhywe’vegivenyoutheletter
