状语从句 1．状语从句的引导词与介词的用法比较；状语从句与定语从句引导词的辨析。 2．能够辨别同类状语从句中近似连接词的用法差异。 3．whatever，whenever，wherever等引导词与no matter wh等引导词的不同用法。 2011年高考对条件状语从句的考查稳中有升。2012年考查的重点仍然是考生容易混淆的近似连词的用法，试题的结构将越来越复杂，设问的角度将越来越多样化。 1．when, while, as的区别 这三个词都可以用作连接词，表示时间关系，但有所区别。 (1)when表示时间关系时，意思常常是“当(在)……的时候”。主句和从句中的动作或事情可以同时发生，也可以先后发生。例如： When we were at school, we went to the library every day. I’ll go when I have had my dinner. The film had begun when we arrived at the cinema. 注意：when有哪些通常所在的句型？ (2)while 用作连接词表示时间关系时，意思也是“当(在)……的时候”，主句中的动作或事情在从句中的动作或事情的进展过程中发生。它有时可与when通用，但它只能指一段时间(a period of time)，而不能指一点时间的(a point of time)。如上面第一个例句中的when，可以用while代替；而第二个例句中的when，就不能用while代替。例如： While I am washing the floor, you can be cleaning the windows. While也可表对比。 I like reading while he prefers listening to music. 谚语：Strike the iron while it is hot. (3)as用作连接词表示时间关系时，意思也是“当(在)……时候”，往往可与when或while通用，但它着重指主句和从句中的动作或事情相并发生。例如： I saw him as he was getting off the bus. As he walked on, he felt himself getting more and more tired. As time passes by, we grow older and learn more. As industry develops,more and more farmland has been taken up. While I am washing the floor, you can be cleaning the windows. While也可表对比。 I like reading while he prefers listening to music. 谚语：Strike the iron while it is hot. (3)as用作连接词表示时间关系时，意思也是“当(在)……时候”，往往可与when或while通用，但它着重指主句和从句中的动作或事情相并发生。例如： I saw him as he was getting off the bus. As he walked on, he felt himself getting more and more tired. As time passes by, we grow older and learn more. As industry develops,more and more farmland has been taken up. 2．一些表示时间的名词短语也可用来引导时间状语从句 the minute, the moment, the instant, every time, the last time, every time。如： The first time I got to the island, I was amazed by its beauty. The moment I entered the room, I smelled something unusual. Every time I visit him, he is always reading. 3．directly和immediately也可作为连词，引导时间状语从句，意为“一……就……”，相当于the moment/the instant和as soon as。如： I knew something was wrong directly I arrived. The boys did all
