在句中作目的狀語的從句稱為目的狀語從句。目的狀語從句可置於句首成句尾。常用引導詞有so that,in order that,for fear that,in case(that),for the purpose that等
1.so that 意為「以便,為了」,表示目的。so that 常位於句中連接兩個分句,從句中多用can, could, may等情態動詞。例如:
I got up early so that I could get to the station in time.
I』ll tell you all the facts so that you can judge for yourself.
so that短語中有時可省略that。
Speak louder so(that )the people in the hall
can hear you.
大聲點兒講,以便讓大廳裡的人都能聽清。
2.in order that
in order that 常用於正式文體。可置於句首,也可置於句尾。
I hurried finish my homework in order that I could be in time for wonderful TV programmes.我匆匆地趕完成我的作業以便能夠趕上看精彩的電視節目。
3.注意:so that,in order that引導的目的狀語從句中常常含有may/ might/will/
would/ shall/should/can/ could等。
Take this medicine so that you can recover
soon.
吃這藥,以便你能很快康復。
She spoke very slowly in order that we could
follow her.她講話很慢,以便我們大家都能聽得懂。
4.目的狀語從句與不定式、介詞短語的互換
當從句主語與主句主語一致時,可用so as to,in
order to.
He worked day and night in order that he
could succeed
-He worked day and night in order to succeed.
他夜以繼日地工作想要獲得成功。
We'll sit in the front of the hall so that we can hear better.
---we'll sit in the front of the hall so as to/in
order to hear better.
我們將坐在大廳的前面,以便能聽得更清楚。
5.so that引導的目的狀語從句和結果狀語從句的區別。
so that既可引導目的狀語從句,又可引導結果狀
語從向。引導目的狀語從向時,從句的謂語動詞裡常有cam, could,may, might等情態動詞,而引導結果狀語從句時則沒有
He always works hard so that he may make great progress.他總是努力學習,這樣他才可能會取得很大的進步。(目的)
Nothing more was heard from him so that we began to wonder if he was dead.
此後再沒收到他的消息,於是我們開始懷疑他是不是死了。(結果)
6.for fear (that),in case,for the purpose that引導的目的狀語從句
for fear that表示目的時,意為「唯恐,以防」;
in case意為「目的是,以防」;for the purpose that意為「為了...目的」。例如:
Take an umbrella with you in case it should rain.帶著傘以防下雨。
for fear that 和 in case 等同但是要注意的是,for fear that比較通俗。口語中常用in case。
