2. 连词until, so that及although引导的状语从句
( 1 ) not... until...的用法
until意为“直到......”。单独使用时,until和till通常可以互换使用,但要注意的是till一般只用于句中,而until即可以放在句首,也可以放在句末。
The noise of the street didn’t stop until midnight.
He lived with his parents until/ till he graduated from college.
注意: 当主句的动词为非延续性动词时,要用not...until...结构;当主句的动词为延续性动词时,可用till 或until。
( 2 ) so that引导的目的或结果状语从句
① so that意为“以便”,引导目的状语从句时,一般放在主句后,且不用逗号隔开。目的状语从句表示动机(即一种可能性),而非事实。因此,从句中常含有can, will, could, would, should等情态动词。
He too a tai so that he could get there earlier.
② so that意为“以致于;结果”,引导结果状语从句,陈述的是客观事实,常常不带情态动词。
I studied English hard so that I passed the English eam.
( 3 ) although conj. 虽然
① 做连词时,although和though通常可以相互转换。
Although/ though she smiled, she was angry.
② although 常放在从句的开头,当用连接词语或短语时,though更为常用且位置灵活,不仅局限在开头。
Wiser though poorer 尽管穷一些但更有头脑
③ 以下情况只用though。
a. 与even连用时用though表示强调,这里的even though = even if,意为“即使......也......”。
b. 当让步状语从句指某种假设情况时,通常用though,而不用although。
Though all the world were against me, I should still hold to my opinion.
就算全世界都反对我,我还是坚持我的观点。
c. Though可以独立用作副词,常放在句末,意为“还是,仍然,可是,然而”.
It’s hard wor. I enjoy it, though.
④ though引导让步状语从句时可以倒装,而although引导的让步状语从句则不能。
Bravely though they fought, they had no chance of winning.
注意:although和though在句中不能与but连用,但可与副词yet连用。即句中用了although或though就不能再使用but了。
Although it was so cold, he went out without an overcoat.
