三、重点句式
1. 状语从句的省略
教材原句：I take notes while listening and reading. (page 7)
【句式分析】while listening and reading是“连词+分词(短语)”结构，是状语从句while I am listening and reading 的省略形式。
例：Work hard when (you are) young, or you'll regret.
年轻时需努力学习,否则你会后悔的。
【学法点拨】
①状语从句的省略条件:当时间、条件、让步、方式等状语从句的主语与主句主语一致(或者从句主语是it),且从句谓语有be动词时，可以将从句的主语和be动词一起省略,构成状语从句的省略形式。.
While walking the dog, he was careless and it got loo and was hit by a car.
追狗的时候,他太大意了,狗挣脱后被车撞了。
When (it is) necessary , you can look up the word in a dictionary.
必要的时候你可以在词典里查这个单词。
②满足了以上省略条件,如果从句主语和谓语动词是主动关系,就用链词＋现在分词”结构,如果是被动关系,就用“连词＋过去分词”结构。
If (it is) heated , water can turn into vapour. 如果受热,水会变成蒸汽。
