一、我們看看在狀語從句中很重要的目的狀語從句,目的狀語從句的定義是:用來說明主句中謂語動詞發(fā)生的目的的從句叫做目的狀語從句,從句部分是用以補充說明主句中謂語動詞發(fā)生的目的。用來引導目的狀語的從句的有:that(以便), so that(以便), in order that(為了;以便),Lest(免得;唯恐), for fear that(生怕;以免)等詞引導;例如:
1. You must speak louder so that /in order that you can be heard by all.
大聲說,以便大家都能聽到你的聲音。
2.They develop their skills so that they can do things better and better.
為了把事情做得更好,他們提高了他們的技術。
3.I've written it down in order not to forget.
為了不會忘記,我把它寫了下來?!?br> 4.He shouted and waved so as to be noticed.
為了引起注意,他一邊喊著一邊揮舞著。
5. He wrote the name down for fear that(lest) he should forget it.
為了防止忘記,他把這些名字都寫下來了。
6. Better take more clothes in case the weather is cold.
以防天氣變冷,最好多帶點衣服。
7.Shut the window for fear that it may rain.
把窗子關上以防下雨。

二、學習目的狀語從句應注意以下兩點:
1. 目的狀語從句中常含有can,could,may,might,should等情態(tài)動詞。 例如:
I got up early so that I could catch the first bus.
我起得很早,目的是為了趕上頭班公共汽車。
2. 在口語中so可以引導目的狀語從句。例如:
We'll sit nearer the front so we can hear better.
我們坐的靠前一點,因此,我們聽得清楚一點。
