You will be lucky if he lets you go without a ticket.However,this does not always happen.
如果他不给你开罚单就让你走,那是你运气好。不过,这种事是不常有的。
I'd like to go with you;however,my hands are full.
我很想和你一块儿去,可是我很忙。
2.but
but是连词,意为"但是",用来引出相反意见或不同情况,常用于口语中。如:
I'd asked everybody but only two people came.
每个人我都请了,却只来了两个人。
3.while
while是连词,意为"却,然而",表示对比或用于引出相反的情况。如:
You like playing tennis,while I like reading.
你爱打网球,而我爱看书。
二、表示让步关系的从属连词
1.although与though
(1)这两个词意思相同,通常可以换用,但although语气较重,通常放在句首,并用于正式场合。如:
I'd quite like to go out,although/though it is a bit rainy.虽然下着小雨,但我还是很想出去。
Although/Though it is snowing,it is not very cold.
虽然下着雪,但天并不是很冷。
(2)though作"尽管"讲,引导的让步状语从句可以倒装,但although没有这种用法。如:
Poor though he is,he is happy.
尽管很穷,但他很开心。
Child though she was,she drew wide audiences.
尽管她还是个孩子,却吸引了大批观众。(child前不用冠词a)
(3)although只用作连词,而though除作连词外,还可用作副词,常置于句末;句子较长时,也可置于句中。如:
He's a bad manager.There's no reason,though,to dismiss him.
他是个差劲的经理,然而还是没有理由免他的职。
(4)although和though用作连词时不能和but连用,但可以和yet,still等连用。如:
Although he lives alone,yet he is happy.(=He lives alone,but he is happy.)
虽然独自生活,但他很开心。
2.as
as引导的让步状语从句要使用倒装语序。从句结构为:名词/形容词/副词/动词+as+主语+谓语。如:
