脚根痛是什么原因:对于连词和从句有点糊涂。麻烦看一眼,谢谢

是不是很多连词只是连接两句话,而这两句话并不起到主从句的作用。比如
I was under the impression that he was a very slow boy until he succeeded in writing a big book.
我们不能说until he succeeded in writing a big book.这句是前面那句的从句吧。
他们之间只是用until连接起来形成一句话,使得结构更加紧密。

是吧?

谢谢

until 所引导的是一个状语从句,表示这件事情发生的时间。意思就是,在他写成那本书后,我才改变了对他的印象,以前我还以为他是个很拖沓的人呢。

在这里until所连接的两句话是有主从关系的,后面是从句,前面是主句。

当然有些连词所连接的两句话是没有主从关系的,比如and,例句:

I love her,and she loves me too.前后两部分是并列的。

1 并列连词与并列结构

并列连词引导两个并列的句子。
1) and 与or
注意:and 还可以和祈使句或名词词组连用表示条件。(or也有此用法)

Make up your mind, and you'll get the chance.
= If you make up your mind, you'll get the chance.
One more effort, and you'll succeed.
= If you make one more effort, you'll succeed.

2) both …and 两者都
She plays (both) the piano and the guitar.

3) not only…but (also), as well as不但…而且)
She plays not only the piano, but (also) the guitar.

注意: not only… but also 关联两个分句时,一个分句因有否定词not 而必须倒装。
Not only does he like reading stories, but also he can even write some.

4) neithe…nor 意思为"既不……也不……"谓语动词采用就近原则,与nor后的词保持一致。
Neither you nor he is to blame.
表示转折或对比

1) but表示转折,while表示对比。
Some people love cats, while others hate them.

典型例题
--- Would you like to come to dinner tonight?
--- I'd like to, ___ I'm too busy.
A. and B. so C. as D. but
答案D。but与前面形成转折,符合语意。而表并列的and, 结果的so,原因的as都不符合句意。

2) not…but… 意思为"不是……而是……"
not 和but 后面的用词要遵循一致原则。
They were not the bones of an animal, but (the bones) of a human being.
表原因关系

1) for
for是并列连词,不能置于含两个并列分句的句子的句首,只能将其放在两个分句中间。
2) so, therefore
He hurt his leg, so he couldn't play in the game.

注意:
a. 两个并列连词不能连用,但therefore, then, yet.可以和并列连词连用。
You can watch TV, and or you can go to bed.
He hurt his leg, and so / and therefore he couldn't play in the game.

b. although… yet…,但although不与 but连用。

这个问题,我还是不明白你想问什么。
但是就这句话而言,until在这里是句子要表达清楚的意思的必需的成分在里面,就是这样用的。
建议你把你的问题说得再明白些。

这句话应该这么理解:直到他成功写完一本巨著后,我才不认为他是一个很拖沓的男孩.

连词所连的句子不一定都是主从句的关系,所以这是很正常的.

你说得非常正确.
