(1)when的特殊用法：be doing when...正在干某事这时……，该句型中when用作并列连词，表示“那时，这时”。 (2)while的特殊用法：作并列连词，“而，却”；作从属连词，“尽管”，相当于although。 (3)not...until句型的强调和倒装用法。 (4)It will be＋一段时间＋before...多久之后才…… (5)It is＋一段时间＋since.... (6)It was＋具体时间＋when...
(7)every time, each time, next time, the first time, the moment/minute/instant...等名词短语引导时间状语从句，表示“每次……”“下次……”“第一次……”“一……就……”等。 2．地点状语从句 由where, wherever引导，可放在主句前，也可放在主句后，where指“在某一地方”，wherever指“在任何一个地方”。但若表示抽象意义，则从句要放在主句之前。 3．条件状语从句 一般由if, as long as, unless, once, on condition that以……为条件，supposing/suppose如果/假使， on the understanding that以……为条件，in case以防，only if只要等引导。 4．原因状语从句 常用的连词有because, since, as, now (that)既然，seeing that鉴于……，considering that考虑到，由于，in(that) 因为等。 5．结果状语从句与目的状语从句 结果状语从句通常由so that, so...that, such...that来引导；目的状语从句通常由so that, in order that, in case, for fear that, lest来引导。 6．让步状语从句 连词有although/though, whether...or..., even though/even if, as, whatever, whoever, whichever, whenever, wherever, however, no matter what/when/how/who/where/which等。 需要注意： (1)although/though一般可互换使用，可以和yet, still连用，但是不能和but连用。 (2)though还可用作副词，“可是，然而”之意，置于句末，并且有逗号和句子隔开。 (3)as引导的让步状语从句要倒装，把从句中的表语、状语或者动词原形置于句首。若表语是名词，前置时要省略冠词。 (4)whoever, whatever, whichever等也可以引导名词性从句。 7．方式状语从句 由as, just as, as if/though引导。as if/though引导的方式状语从句，如果从句所述的情况可以实现，用陈述语气；如果从句所述的情况不可能实现，用虚拟语气。 8．比较状语从句 通常由as...as, not as/so...as, than, the more...the more...引导，比较状语从句常用省略结构，要特别注意比较内容要一致。 9．状语从句中的省略 在状语从句中，如果主句和从句的主语一致或是it，且谓语动词中有be的某种形式时，从句的主语和be常省略。 5．(2010·天津)As a new graduate, he doesn't know ________ it takes to start a business here. A. how
B. what C. when
D. which 答案与解析：B 宾语从句暗含it takes...to do sth.句型，因此应用what引导宾语从句并充当从句中的宾语。 【考点诠释】 1．名词性从句一直是多年来高考的热点，试题多是考查引导名词性从句的引导词。引导名词性从句的引导词主要分为三类：连接词(that, whether)、连接代词和连接副词。解答此类题目首先要运用简单句的基本句式，分析从句的成分是否完整。 如果从句缺主语、宾语、表语，一般要考虑选择连接代词。如果从句不缺基本成分，即不缺主语、宾语、表语，要参考句意进行选择。可以选择从属连词that，也可以选择从属连词whether或if，有时还可以选择连接副词。 2．同位语从句 (1)同位语从句是用以解释说明某一名词的内容和实质的从句。不起修饰作用。 (2)同位语从句常用的引导词有that, whether, why, where, how等，if不引导同位语从句。在同位语从句中，that, whether不作成分，其他连接词具有实义，同时在同位语从句中作句子成分。 (3)通常可跟同位语从句的名词有fact, news, order, message, doubt, idea, belief, reason, thought, suggestion, question等。 考点五十一 that, what引导的名词性从句 【真题再现】 1．(2010·北京)I want to be liked and loved for ________ I am inside.

B. what C. how
D. whether 答案与解析：B 此处是由what引导的主语从句，指代It的具体内容，It是形式主语，所以这里选B项。 【考点诠释】 what与that的区别 what在名词性从句中可以作主语、表语或宾语；that在名词性从句中不作成分，只起连接作用，一般在从句中不缺少主语、表语或宾语时使用。 (1)What we need is time. 我们需要的是时间。(主语从句，what在从句中作宾语，不可以省略)
(2)What is needed is time. 所需要的是时间。(主语从句，what在从句中作主语，不可以省略) (3)That he failed in the test again really puzzled us. 他又一次没通过考试，这让我们迷惑不解。(主语从句，that在从句中不作成分，不可以省略) (4)I don't know that he was seriously ill. 我不知道他病得很严重。(宾语从句，that在从句中不作成分，可以省略) 注意对比以下句子： What__he__said is wrong.他说的话是错的。 That__he__said__so is wrong.他这么说是错的。 两个句子都是主语从句，第一个句子中what作said的宾语；第二个句子中so作said的宾语，that不作成分，不可以省略。 另外，有时句子不缺成分时要用连接副词，使句子意思更加完整。 The problem is how/where/when/whether we can get more money. 考点五十二 whever引导的名词性从句 【真题再现】 1．(2010·重庆)To improve the quality of our products, we asked for suggestions ________ had used the products.
