状语从句
状语从句就是充当句子状语的从句,它可分为时间、地点、方式、比较、原因、结果、目的、条件和让步等从句.
让步状语从句
让步状语从句由as,though,although,even if/though,whatever,whoever,whichever,however,whether… or…,no matter+ wh-词,be,while,granted that,for all that等引导.如：
While/Although he has some shortcomings,he also has some good points.虽然他有一些缺点,但也有一些优点.
Be it rain or shine,I must go.不管天晴还是下雨,我必须去.
注：as 和though引导的让步状语从句通常用倒装结构,as必须用倒装结构,though可用也可不用倒装.这种倒装通常是把从句中的表语、状语或谓语动词放在句首.如：
Selfish as/though he is,he is not without merits.尽管他自私,但不是没有优点.
定语从句
定语从句也称为关系从句或形容词性从句,由关系代词（who,whom,whose,which,that）或关系副词（as,when,where,why）等引导.关系词除了起引导作用外,还在从句中指代前面的先行词,并在从句中担任一定的成分.如：
The car which was stolen has been found.（which 指代先行词car,在从句中作主语）
The house whose windows are broken is empty.(whose 是所有格,在从句中作定语)
I shall never forget the day when I entered the university.(when指代先行词day,在从句中作时间状语)
明白吗
