because, since, as, for, now( that), considering (that), seeing (that) 考虑到/鉴于鉴于/由于/因为考查重点 because, since, as, forbecause— 直接原因,非推断.语气最强.回答 whysince – 通常放句首.译为“既然”as– 不谈自明的原因,语气最弱.for– 放句中,对前面一句话的内容的补充说明 。1.Parents should take seriously their children's requests for sunglasses

  ____eye protection is necessary in sunny weather.            (2004 上海 )   A. because             B. though               C. unless           D. if2.Jenny was very sad over the loss of the photos she had shot at   Canada,____this was a memory she especially treasured.(2006 广

地点状语从句由 where. wherever 引导。 where 指“在某个地方”,wherever 指“无论哪里,在任何一个地方”,在使用时:一要注意两者的含义区别。二要注意状语从句和定语从句的区别。三要注意在状语从句中不可使用介词 +which 引导。出题者既考状语从句又考定语从句和状语从句的区别。还加入名词性从句这一干扰项。

1.If you are traveling____the customs are really foreign to your own , please do as the Romans do. (2006 天津 ) A.in which  B.what C.when D.where2.In peace , too , the Red Cross is expected to send help___there is huma

目的状语从句和结果状语从句 引导目的状语从句连词有: in case, so that, in order that, for fear that 。 so that 引导状语从句只能置于主句之后。 In order that 引导状语从句可放主句之前或之后。目的状语从句的谓语常含有 can , could , may , might 情态动词。这也是与结果状语从句的一个区别。引导结果状语从句的连词有: so that , so…that ,such…that. 结果状语放在主句之后。 注意:在 so…that , such…that 结构中一般成分齐全。这也是与 as 引导定语从句的区别。在 so…as , such…as   这一结构中,as 引导定语从句,在句中做成分。

if as/so long as as far as unless in case (如果)

suppose/supposing (that)

Providing/provided (that)

on condition thatgiven (that) 条件状语从句一般考查三点:

1) 在条件状语从句中常用一般现在时表示一般将来时,用一般过 去时表过去将来时。 2)if , unless , in case 是考查重点。3)when 还可表条件,这一点不可忽视。意思是:既然,考虑到。 如: How can they learn anything when they spend all their spare time watching television ?他们把所有空闲的时间都用来看电视了, 还能学到什么东西呢?

让步状语从句的连词有: though /although“ 尽管”, even if /even though“ 即使”, no matter how(what , when , which , who , where) , however(whatever , whenever , whichever , whoever , wherever), as“ 尽管” 1)although 与 though 可互换,都可以与 yet , still 连用,但不能和 but 连用。2)However 引导让步状语从句时后紧跟形容词或副词。3)While 也可引导让步状语从句,这一点特容易被考生忽视。4)Whatever 修饰名词,“无论什么”, however 修饰形容词、副词,“无论多么, 无论怎么”。5)even if/even though( 即使 ) 与 as if/as though( 好像 ) 这两组学生容易混淆, 也是出题者关注的对象,平时要记准含义。

状语从句中从句的省略现象

(08· 安徽 )— Have you got any particular plans for the coming holiday? — Yes, , I’m going to visit some homes for the old in the city. A. If ever B. If busy C. If anything D. If possible

考查省略句。此句的意思是:“你们为即将到来的假期做了特别的计划没?”“是的,如果有可能的话,我们将去拜访这座城市的老年之家。” if

possible 是 if it is possible 的省略形式。
