从句是相对于主句而言的,即它是从属于某一个主句,而不能单独作一个句子。在英语中,
主要有三大从句,即
名词性从句 (包括主语从句,宾语从句,表语从句,同位语从句)、
形容词性从句 (即定语从句)、
副词性从句 (即状语从句,包括时间、条件、结果、目
从句是相对于主句而言的,即它是从属于某一个主句,而不能单独作一个句子。在英语中,主要有三大从句,即名词性从句(包括主语从句,宾语从句,表语从句,同位语从句)、形容词性从句(即定语从句)、副词性从句(即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等)。
主语从句用作主语,如::
That the earth is round is true. 地球为圆的是真实的。
宾语从句用作宾语。如:
Do you know where he lives?
表语从句用作表语,如:
My opinion is that you should not go alone. 我的意见是你不应单独前往。
同位语从句用于解释说明前面的名词。如:
The fact that the earth is round is true. 地球是圆的的事实是真实的。(that从句用于解释说明the fact)
定语从句相当于一个形容词,用于修饰前面的名词。如:
The student who answered the question was John. 回答问题的学生是John.
状语从句相当于一个副词,如:
When it rains,
I usually go to school by bus. 天下雨时,我通常坐公共汽车上学。(
时间状语)
If he comes tomorrow,
you will see him. 如果他明天来,你就可以看见他。(
if 引导的条件状语从句,其结构为:if +状语从句,+主句)。要注意在状语从句中有一个规则是“主将从现”,即主句是将来时,则从句要用一般现在时表示将来。
He returned home to learn his daughter had just been engaged.他回家后得知女儿刚刚订婚了。(
结果状语,结果状语只是仅限于learn(得知),find(发现),see,hear,to be told(被告知),make(使得)等具有界限含义的动词。)
You must speak louder so that /in order that you can be heard by all. 你必须大声说话,才能让所有人听到你说话。(
目的状语,可以由that,so that, in order that, lest(唯恐;以免;惟恐;生怕), for fear that(唯恐,害怕;生恐;惟恐;生怕),in case(假使;免得; 以防;也许)等词引导。)
Since /As the weather is so bad,
we have to delay our journey. 天气那么糟,旅行推迟了。 (
原因状语从句,常用because, since, as, for fear ( 恐怕 ), seeing that ( 既然 ) , now that (=since), considering that( 考虑到 ) 等引导。)
Though/Though he was worn out, (still)
he kept on working. 虽然他已经精疲力竭了,但仍然继续工作。 (
让步状语从句,引导的连词主要有以下这些:
though,although, as; even if, even though;whether…or…; no matter+疑问词,疑问词-ever.)
Where I live there are plenty of trees. 我住的地方树很多。(
地点状语从句,通常由where,wherever 引导。)
As water is to fish,
so air is to man. 我们离不开空气,犹如鱼儿离不开水。(
方式状语从句通常由
as, (just)as…so…, as if, as though引导。)
主句和从句的划分方法是相同的。句子的成分从谓语动词处来划分比较容易。谓语动词前面的部分是主语,后面常接宾语,修饰谓语动词的是状语,修饰主语、宾语的是定语,若谓语是系动词,则系动词后的部分是表语。如:
I am a teacher. 其中,I 是主语,am是谓语,a teacher 是表语。
He likes playing football very much. 其中,he是主语,likes是谓语,playing football是宾语,very much是状语。
