as用法总结

动词原型置句首

• 结构为：v. + as + 主语 + 助动词may,might,will,would,can,could,do,does,did） Fail as I did,I would never stop trying.尽管我失败了，但我决不会停止尝试。 Try as he will,no man breaks wholly loose from his first love,........

• 若动词是及物动词，则宾语也随着动词提前： Lose money as I did,I got a lot of experience.尽管我费了不少钱，但是获得了很多经验。

• as可以替换为that或though,尽管较少这样用，不可以用although。 Odd though it sounds,cosmic inflation is a scientifically plausible consequence of some...(though代替as来表示让步)

as/so + 形容词 + as + 主谓结构，放在句首表示让步（较少见） As much as john hates to do it,he must stay at home and study tonight.尽管约翰不愿意，但他今晚还得待在家里学习。 As amusing and perceptive as graffiti may sometimes be, it has by no means won universal approval.尽管涂鸦有时可以怡人情趣并发人深思，但它决不会赢得普通的认同。
