1. _____ is often the case, we have worked out the production plan.(2004,江苏)

A.Which   B.When   C.What   D.As  

分析:as引导评述性状语从句,可以放在主句前,也可以放在主句后。which引导定语从句,不能放在主句前,只能放在主句后。选D。

2. A lot of language learning, ____has been discovered, is happening in the first year of life, so parents should talk much to their children during that period .(2012,安徽) A.as   B.it   C.which   D.this  

句意:正如研究发现,很多语言学习发生在出生后的第一年,所以,在那个阶段,父母应该多和孩子说话。选A。

3. The owner of the cinema needed to make a lot of improvements and emply more people to keep it running, ____meant spending tens of thousands of pounds.(2006,江苏)  A.who   B.that   C.as   D.which

分析:which (代词)在从句中作成分(作主语),as (连词)在从句中不作成分。选D。

4. If the man is only interested in your looks, ____ just shows how shallow he is. (陷阱题)

A. as   B. which   C. what   D. that

分析:容易误认为逗号后是非限制性定语从句,从而误选A或B。其实,注意逗号前是一个条件状语从句,逗号后是该状语从句的主句,that 在此代表前文所述的情况,用作主句的主语。选D。
