第二部分基础语法突破专题十一并列句和状语从句，考点清单并列句并列句由两个或两个以上的简单句构成。
在并列句中，这些简单句常由并列连词连在一起。
并列连词所连接的简单句被称为分句。
并列连词主要表示并列、选择、转折、因果等关系。
一、表示并列关系的连词表示并列关系的连词有and,both…and…,not…but…, not only...but also,neither・・・nor・・等。
I came here in2001,and I have lived here ever since.Not only was the city polluted but also the streets were crowded.二、表示选择关系的连词表示选择关系的连词有or,either・・・or・・・等。
Now you can have a rest or you can go to the cinema.三、表示转折关系的连词表示转折关系的连词有but,yet,while等。
It's an old car,but it's very reliable.I drink black coffee while he prefers it with cream.八、方式状语从句方式状语从句用as,as if/though引导。
as if/though 引导的从句常用虚拟语气（但是当说话者认为句子所述的是真实的或极有可能发生或存在的事实时,as if从句要用陈述语气）。
The worker finished his work as the boss told him.She treats her husband as if he were a stranger.九、比较状语从句比较状语从句由as,than引导，从句中通常省略与主句相同的部分，或用助动词do,does,did代替与主句部分相同的谓语。
