若表语是单数名词,前置时要省略冠词。
Child as/though he is, he can tell the names of all the cars.尽管他是个孩子,但他能说出所有车的名字。
Much as/though I like it, I won't buy it, for it's too expensive.虽然我很喜欢它,但不会买,因为它太贵了。
3.whether ...or .../whether ...or not(不管……还是……);疑问词+ever与no matter+疑问词(不管……;无论……)。
I have decided to take the job offer, whether it is good or bad.不管好坏,我已经决定接受这份工作邀请。
Whatever (=No matter what) you say, he won't believe you.(让步状语从句)无论你说什么,他都不会相信你。
