如何学习用连词as引导的状语从句

1、时间状语从句连词as作正当。。。的时候，随着...讲，例如He came up as I was speaking, 再如as a little girl she began to operate a computer

2、在时间状语从句中，我们还可用as and when表示当。。。时，主要用来指一件不夺卺臣囔肯定的将来的事或一个行动，例如they wil造婷用痃l decide on their team as and when they qualify for the competition.

3、原因状态从句连词as或inasmuch as作“由于，因为”来讲，例如as this problem is of great interest, we will discuss it once again

4、让步状态从句连词as作虽然，尽管来讲，例如Much as I should like to see you, I'm afraid you could not have any free time

5、一般比较从句内常省略与主语相同的成分，as...as和...一样的， 这里第一个as是副词，第二个as是连词，例如this line is as long as that one(is)

6、as...+as+所比拟的事物的含义为，如...一样，例如it is as white as snow，其白如雪，as quick as lightning快如闪电， as light as a feather轻如鸿毛
