顧名思義,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。
上海新東方酷學(xué)酷玩冬令營介紹,表示目的狀語的從句可以由 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);目的狀語從句的謂語常含有may, might, can, could, should, would等情態(tài)動詞。
例如:you must speak louder so that /in order that you can be heard by all.
he wrote the name down for fear that(lest) he should forget it.
better take more clothes in case the weather is cold.
學(xué)習(xí)目的狀語從句應(yīng)注意以下兩點(diǎn):
(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(dǎo)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(diǎn),因此,我們聽得清楚一點(diǎn)。
1、in order that與in order to的區(qū)別:
in order that+從句 in order to+動詞原形 ( in order to后面加的那個不叫目的狀語從句,叫目的狀語) 例如:
he got up early in order to take the first bus.
= he got up early in order that he could take the first bus.(他起床很早是為了趕上第一班 公共汽車)
目的狀語從句的一個特點(diǎn):由于目的都是未來的行為,所以從句中一般用表示未來可能性時態(tài),比如上面句中的could。當(dāng)然還可以用will,would,can,等 。
2、so that既可引導(dǎo)目的狀語從句,也可以引導(dǎo)結(jié)果狀語從句。
1)其引導(dǎo)結(jié)果狀語從句時,so that翻譯為“以至于...”,經(jīng)常可以和so/such...that...轉(zhuǎn)換,且從句只能放在主句之后。如:he got up late so that he was late for school. = he got up so late that he was late for school.
2)其引導(dǎo)目的狀語從句時,從句只能放在主句之后,此時可以和in order that換用。如:he got up early so that he could take the first bus. = he got up early in order that he could take the first bus.
