要点汇总
顾名思义,用来讲 明主句中谓语动词发生的目的的从句叫做目的状语从句。 表示目的状语的从句可以由 that(以便),so that(以便), in order that(为了;以便),Lest(免得;唯恐), for fear that(生怕;以免)等词引导;目的状语从句的谓语常含有may, might, can, could, should, would等情态动词。
比如: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 tak e more clothes in case the weather is cold.
学习目的状语从句应注意以下两点:
(1)目的状语从句中常含有c an,could,may,might,should等情态动词。 比如:
I got up early so that I could catch the first bus. 我起得非常早,目的是为了赶上头班公共汽车。
(2)在口语中so可以引导目的状语从句。比如:
Well sit nearer the front so we can hear better. 大家坐的靠前一点,因此,大家听得了解一点。
1、in order that与in order to有什么区别:
in order that+从句 in order to+动词原形 ( in order to后面加的那个不叫目的状语从句,叫目的状语) 比如:
He got up early in order to take the first bus.
= He got up early in order that he could take the first bus.(他起床非常早是为了赶上第一班 公共汽车)
目的状语从句的一个特征:因为目的都是将来的行为,所以从句中一般用表示将来可能性时态,譬如上面句中的could。当然还可以用will,would,can,等 。
2、so that既可引导目的状语从句,也可以引导结果状语从句。
1)其引导结果状语从句时,so that翻译为以至于...,常常可以和so/such...that...转换,且从句只能放在主句之后。如:He got up late so that he was l ate for school. = He go t up so late that he was late for school.
2)其引导目的状语从句时,从句只能放在主句之后,此时可以和in order that换用。如:He got up earl y so tha t he could take the first bus. = He got up early in order that he could take the first bus.
容易见到考法
对于目的状语从句的考查,多以单选和完 形填空的形式,从 连词的意义角度让大伙选择连词。
典型例题:Ann listened carefully ||||| she could discover what she neede d.
A. such that B. in order that C. because D. even though
分析:题干的意思是为了可以发现自己需要的东西,安认真听讲。非常明显从句表示的是目的。such that本身是错误短语,because 表示缘由,even though是尽管的意思,不符合题意。
答案:B
误区提醒
怎么样不同目的状语从句中的so that与结果状语从句中的so that的使用方法,这是大家应该注意的。目的状语从句的so that是连着的,结果状语从句是分开的,即sothat. so that是目的状语从句,是为了什么什么,有目的的意思。而sothat是结果状语从句,是这样如何如何结果是什么。仔细领会一下吧!
典型例题:I get up so early I can not be late
A. that B . so that C.such that D.in order
分析:题干的意思是我起床这样早以便于我可以不迟到。从句表示目的,第一排除C,由于such that本身是错误短语,在排除in order,由于它后面不可以跟句子;由于句子中有so,所以大伙可能选A,假如选它,那句子的意思是我起床这样早结果我可以不迟到,显然说不通,所以排除。
答案: B
