高中英语题?
表语从句连接词:that/whether/asif/asthough
连接代词:who/whom/whose/which/what
连接副词:when/where/why/how/because
1)that在从句中仅起连接作用,无实际意义,在句中不做任何成分,不能省略。
2)whether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.
3)What在表语从句中充当主语宾语表语,表示什么,什么样子,…的人或事.
Thequestioniswhatcausedtheaccident.
2.Thatmountainisnolongerwhatitusedtobe.
3.Whathetoldyouwaswhathadbeendiscussedatthemeeting.4)who在表语从句中充当主语,宾语,表语,表示谁。.1.Theproblemiswhocoulddothework
2.Mytroubleiswho(whom)Icanturnto.
5)which在引导表语从句时,常充当定语,表语表示哪一个,哪一些。
望采纳,谢谢!
