一、我們看看在狀語(yǔ)從句中很重要的目的狀語(yǔ)從句,目的狀語(yǔ)從句的定義是:用來(lái)說(shuō)明主句中謂語(yǔ)動(dòng)詞發(fā)生的目的的從句叫做目的狀語(yǔ)從句,從句部分是用以補(bǔ)充說(shuō)明主句中謂語(yǔ)動(dòng)詞發(fā)生的目的。用來(lái)引導(dǎo)目的狀語(yǔ)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(dǎo);例如:
1. You must speak louder so that /in order that you can be heard by all.
大聲說(shuō),以便大家都能聽(tīng)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(shù)。
3.I've written it down in order not to forget.
為了不會(huì)忘記,我把它寫(xiě)了下來(lái)。 
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(xiě)下來(lái)了。
6. Better take more clothes in case the weather is cold.
以防天氣變冷,最好多帶點(diǎn)衣服。
7.Shut the window for fear that it may rain.
把窗子關(guān)上以防下雨。

二、學(xué)習(xí)目的狀語(yǔ)從句應(yīng)注意以下兩點(diǎn):
1. 目的狀語(yǔ)從句中常含有can,could,may,might,should等情態(tài)動(dòng)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(chē)。
2. 在口語(yǔ)中so可以引導(dǎo)目的狀語(yǔ)從句。例如:
We'll sit nearer the front so we can hear better.
我們坐的靠前一點(diǎn),因此,我們聽(tīng)得清楚一點(diǎn)。
