as引導(dǎo)的讓步狀語(yǔ)從句一定要用虛擬語(yǔ)氣嗎

as用于引導(dǎo)讓步狀語(yǔ)從句，只能用于倒裝句式，并且通�？蓳Q成though（但不能是although），其基本結(jié)構(gòu)是“名詞、形容詞、副詞、動(dòng)詞等+as [though]+主語(yǔ)+其他”。這類句子通常用陳述語(yǔ)氣。如：

Rich as he is, he is not happy. 盡管他很富有，他并不幸福。

Boy as he was, he behaved like a girl. 他雖是個(gè)男孩，但舉止卻像個(gè)女孩。

Much as I like you, I couldn't live with you. 我盡管很喜歡你, 卻不能和你在一起生活。

Lose money as I did, I got a lot of experience. 錢雖然丟了，我們卻得到了許多經(jīng)驗(yàn)。

Hard though they tried, they couldn't make her change her mind. 盡管他們做了很大努力，卻沒(méi)法讓她改變主意。

但有時(shí)從句也用“may [might, would]+動(dòng)詞原形”這樣的虛擬語(yǔ)氣。如：

Clever as you may be, you cannot do that. 盡管你聰明，你卻做不了這件事。

Strange though it may seem, he arrived early. 盡管看來(lái)很奇怪，他卻到得很早。

Try as she might, she could not persuade her friends to go. 不管她怎樣想法，都不能勸說(shuō)她的朋友們?nèi)ァ?/FONT>
