2011高考英语语法考点讲练：主从复合句

　　4.结果状语从句

　　由下列连词引导：that，so…that，so that(从句中不带情态动词)，such…that，with the result that等。

　　注意以下几种结构：

　　①so+adj/adv+that…

　　②such(a/an+adj)+n+that…

　　③so+adj+a/an+n+that=such a/an+adj+n+that…

　　④so many/much/few/little(少)+n+that…

　　注意以上结构与定语从句so/such…as的区别。

　　(so that也可用来引导结果状语从句，但从句中不带情态动词)

　　注意：so that引导的目的状语从句只能放在主句之后，in order that 引导的目的状语从句可以放在主句之前或之后。

　　6.条件状语从句

　　分为真实条件句和非真实条件句(用在虚拟语气中)。

　　表示条件的状语从句可以由if(如果),unless(除非), in case(万一), so /as long as(只要), as/ so far as(就……而言), on condition that(条件是……)suppose(假设)supposing(假设)(仅用在问句中)
