英语语法目的状语从句用法
目的状语从句,从句部分是用以补充说明主句中谓语动词发生的目的的状语从句。以下是小编整理的英语语法目的状语从句用法,希望对大家有所帮助。
目的状语从句的一个特点:由于目的都是未来的行为,所以从句中一般用表示未来可能性时态,当然还可以用will,would,can等等。
1、由so...the...和 such...that...引导的目的状语从句,应该注意可能出现的以下结构,例如:
I am telling you that lest you should make a mistake.
我告诉你这一点,以免你搞错。
so nice a boy that…
such a nice boy that…
so beautiful/diligent/carefully … that…
such (fine weather/great improvement) that…
2、so that引导的结果状语从句是我们在英语学习中经常见到的一个词组,例如:
1)She worked hard so that everything would be ready by 5 o'clock.
她努力工作,以便在五点前是一切都就绪。
2)She looked down so that she should not see his eyes.
她垂下目光,使她看不到他的眼睛。
3)Everyone lend a hand, so that the sowing was done in time.
3、so much so that的用法,该结构用于形容词或副词之后,表示"到如此程度以致于"。例如:
He was very weak, so much so that he could not walk.
I long to visit Beijing, so much so that I dream about it every night.
4、in order(that)"以便" to the end that "为……起见,以便"例句:
1)He works hard in order that his family may be happy.
为了让家人幸福,他努力工作。
2)He shouted at the top of his voice,to the that(=in order that)he might be heard.
他高声呼喊,为的是让人们能听见他的说话。
5、含有情态动词的目的状语从句,例句:
1)I am punishing the child lest he should make the same mistake.
我惩罚那个孩子,以免他再犯同样的错误。
2)She took her umbrella lest it(should)rain.
他带了把雨伞,唯恐天要下雨。
3)Lest the wall(should)collapse,they evacuated the buliding.
他们撤离了大楼,以防墙壁倒塌。
6、in case既可引导目的状语从句,也可引导条件状语从句,主要视句意而定:
1)In case he comes, let me know.
如果他来,告诉我一声。
2)Tell me in case you get into difficulty.
遇到困难请告诉我。
in case引导目的状语从句,从句有时可用“should+动词原形”这样的形式:
Take your coat in case it rains (should rain). 带着雨衣以防下雨。
英语目的状语从句解析
顾名思义,用来说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。
例如:You must speak louder so that /in order that you can be heard by all.
He wrotethe namedown for fear that(lest) he should forget it.
Better take more clothes in case the weather is cold.
目的状语从句应注意以下两点:
(1)目的状语从句中常含有can,could,may,might,should等情态动词。 例如:
I got up early so that I could catch the first bus. 我起得很早,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。例如:
We'll sit nearer the front so we can hear better. 我们坐的靠前一点,因此,我们听得清楚一点。
1、in order that与in order to的区别:
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) 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.(他起床很早是为了赶上第一班 公共汽车)
目的状语从句的一个特点:由于目的都是未来的行为,所以从句中一般用表示未来可能性时态,比如上面句中的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...”,经常可以和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 late for school. = He got 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 early so that he could take the first bus. = He got up early in order that he could take the first bus.
常见考法
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家选择连词。
典型例题:Ann listened carefully _____ she could discover what she needed.
A. such that B. in order that C. because D. even though
解析:题干的意思是“为了能够发现自己需要的东西,安认真听讲”。很明显从句表示的是目的。such that本身是错误短语,because 表示原因,even though是“尽管”的意思,不符合题意。
答案:B
误区提醒
如何区别目的状语从句中的so that与结果状语从句中的so that的用法,这是我们需要注意的。目的状语从句的so that是连着的,结果状语从句是分开的,即so…that. so that是目的状语从句,是为了什么什么,有目的的含义。而so…that是结果状语从句,是“如此怎么怎么样结果是什么”。仔细体会一下吧!
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
解析:题干的意思是“我起床如此早以便于我可以不迟到”。从句表示目的,首先排除C,因为such that本身是错误短语,在排除in order,因为它后面不能跟句子;因为句子中有so,所以大家可能选A,如果选它,那句子的意思是“我起床如此早结果我可以不迟到”,显然说不通,所以排除。
答案: B
