二、让步状语从句
让步状语从句常由以下从属连词引导:
though/although(尽
管,虽然),as,evenif/eventhough(即使),疑问词-ever/nomatter
+疑问词(不管,无论)等。
1.though,although;evenif,eventhough"虽然『尽管”
though,although这两者意思大致相同,一般可互换,都可与
yet,still,nevertheless连用,但不能与but连用。

oftime,moststudentsagreethattheexperienceisworthit.

iteveryyear.(2014*^t京JlF考改编)

as引导的让步状语从句必须以部分倒装的形式出现,被倒装的部分可以是表语、状语或动词原形‘though间或也用于这样的结构中,但although不可以这样用。
Tiredas/thoughhewas,hecontinuedworkinginthefield.
=Though/Althoughhewastired,hecontinuedworkinginthefield.

还是……”
3.whether...or…表示"不论是否;不管是之意。
Ihavedecidedtotakethejoboffer,whetheritisgoodorbad.无论好坏,我已经决定接受这份工作邀请。
4."nomatter+疑问词”或"疑问词-ever"的含义为"不管……都……”,它们引导的让步状语从句可以互换。

Whatever(=Nomatterwhat)yousay,Iwon'tbelieveyou.
(whatever引导让步状语从句)
r11eatwhatever(Hnomatterwhat)yougiveme.(whatever引
导宾语从句)
5.有时while也可以引导让步状语从句,但一般要位于句首。
