1、从句分类,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)。,名词性从句(包括主语从句,宾语从句,表语从句,同位语从句),主语从句用作主语,如: That the earth is round is true. (斜体作主语)表语从句用作表语,如: My opinion is that you should not go alone. (斜体作表语),宾语从句用作宾语。如: Do
2、you know where he lives? (斜体作宾语)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. (that从句用于解释说明the fact),形容词性从句(即定语从句),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. (斜体从句做了student的形容词,回答问题的学生),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),状语从句相当于一个副词,如: When it rain
3、s, 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),s
4、ee,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, for fear that, in case等词引导。),Since /As the weather is so bad, we have to delay our journey. 天气那么糟,旅行就推迟了。 (原因状语从句,常用 bec
5、ause, 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
6、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) asso, 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。,以上是英语中从句的三大分类,一个大的框架结构。每样列举了一个例子,若是需要深入了解,文件夹中有分别关于名词性从句,定语从句和状语从句的三个专题。,
