英语语法常用的目的状语从句联词
状语从句 是指句子用作状语时,起副词作用的句子。以下是小编为大家收集的英语语法的目的状语从句联词,欢迎大家借鉴与参考,希望对大家有所帮助。
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。
表示目的状语的从句可以由that, so that, in order that, lest, for fear that, in case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 wrote the name down for fear that(lest) he should forget it.
Better take more clothes in case the weather is cold.
引导目的状语从句常用的连词有: 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)。
【例如】
Say it louder(so)that everyone can hear you.
大声说,以便大家都能听到你。
I am telling you that lest you should make a mistake.
我告诉你这一点,以免你搞错。
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can,could,may,might,should等情态动词。
【例】
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】
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。
【注意】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)
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,比如上面两句中的could。
当然还可以用will,would,can,等
结果状语从句的连词
以下结果状语从句的一些用法。
1) so … that…/ such ….that
该句式中重要考查的是so和such的区别。应注意以下可能出现的结构:
so nice a boy that…
such a nice boy that…
so beautiful/diligent/carefully … that…
such (fine weather/great improvement) that…
2) so that
Everyone lend a hand, so that the sowing was done in time.
该句式中主要考查so that 与其它短语的区别,如:
I took no notice of him, ___ he flew into a rage.
A.for that B.so that C.in that D.but that
由于so that也可以引导目的状语从句,同学们应特别注意从句中时态的运用。
3) so much so that
该结构用于形容词或副词之后,表示"到如此程度以致于"。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) 注意结构状语从句与too….to..enough to…, so… as to结构的不同。
扩展资料:
在句中作目的的状语从句称作目的状语从句。目的状语从句可置于句首、句中或句尾。
常用来引导目的状语从句的关联词有:so、so that、in order that、for fear that、in case (that)、for the purpose that、lest等。
(一)in order that、so that引导的目的状语从句
In order that常用于正式文体,可置于句首,也可置于句尾,而so that往往只置于句尾,但也有置于句首的,so that短语中有时可省略that。
例句:We shall let you know the details soon so that/in order that you can/may make your arrangements.
不久我们将会让你知道详情,以便你们能够做出安排。
例句:I've decided to learn photography in order that I may record the beauty of nature.
为了能记录大自然的美,我决定学摄影。
注意!不定式结构in order to do/so as to do(逻辑主语相同)或in order for sb. To do(逻辑主语不同)也可以表示目的,可与in order that引导的目的状语从句相互转换,上面两个例句可改为:
We shall let you know details soon in order for you to make your arrangements.
I've decided to learn photography in order to record the beauty of nature.
(二)for fear (that)、in case、lest引导的目的状语从句
for fear (that)表示目的时,意为“唯恐、以防”;in case意为“以免,以防有某种情况发生”;lest意为“以防”。这三个短语或词都相当于in order that……not……,so that……not……。
例句:Shut out the windowlest/in case it should rain.
关上窗以防下雨。
例句:The victims all seemed afraid to say the factsfor fear it might start trouble.
受害人似乎都不敢说出真相,怕引起麻烦。
例句:She pulled away from the windowlest anyone see her.
她从窗口躲开了,免得有人见到她。
例句:I stayed all day at home in case (that) you called.
我整天待在家里以防你打电话。
