真相...引導(dǎo)詞用法①從屬連詞that在從句中不充當(dāng)成分，無意義whether在從句中不充當(dāng)成分，意為“是否”②連接代詞what(ever),which(ever),who(ever),whom(ever),whose在從句中充當(dāng)主語，賓語，表語，定語③連接副詞when,where,why,how在從句中充當(dāng)狀語同位語從句

引導(dǎo)詞Point

1:

為了保持句子平衡，同位語從句有時(shí)可以不緊跟它說明的那個(gè)名詞后面，而是被其它的詞隔開，這種從句叫分割式同位語從句。Theproblemwhethertheyshouldcontinuetodotheexperimenthasbeensolved.ThestorygoesthatWilliamTellkilledthekingwithanarrow.Wordcamethattheirteamhadwon.四、同位語從句的注意點(diǎn)找出同位語從句以及其說明的名詞Point

2:同位語從句的虛擬語氣：在表示“堅(jiān)持，命令，建議，要求”的名詞

后面的同位語從句中，從句謂語動(dòng)詞用“should+動(dòng)詞原形”，should可省略Imadeaproposalthatweshouldgetupearlytomorrow.Myproposalisthatweshouldgetupearlytomorrow.Itisproposedthatweshouldgetupearlytomorrow.Iproposedthatweshouldgetupearlytomorrow.

一堅(jiān)持insist二命令order,command三建議advise,suggest,propose四要求require,request,demand,desire四、同位語從句的注意點(diǎn)Point

3:

doubt的同位語從句有否定詞+doubt的同位語從句，用whether：Thereisnodoubtthat...直接doubt后的同位語從句，用that：Thereissomedoubtthat...Thereisnodoubt

thatitwashisfriendthatplayedtricksonhim.Thereissomedoubt
