让步状语从句
常用引导词：though,although,even if,even though
特殊引导词：as(用在让步状语从句中必须要倒装),while ( 一般用在句首 ),no matter …,in spite of the fact that,while,whatever,whoever,wherever,whenever,however,whichever
Much as I respect him,I can’t agree to his proposal.
尽管我很尊敬他,我却不同意他的建议.
The old man always enjoys swimming even though the weather is rough.
No matter how hard he tried,she could not change her mind.
He won’t listen whatever you may say.
伴随状语从句:用with引导的话,表示在进行一项动作的同时在进行另外一个动作,后面用名词+介词短语,或者直接用动词ing形式.如:The teacher came into the classroom,with books under her arm.She came here,with running.
复合结构就是用一些介词,副词来引导的句子,比较起简单句说有点复杂而已.如 she not only passes the exam but also get a high mark.用with的话,如 with his help,she get a high mark.其中with his help不过是一个状语成分,作条件讲.
