However exciting等于：No matter how exciting the movie may be,we have no time to see it.因?yàn)镹o matter how,或者However 是修飾表語 exciting的,所以必須得把exciting 前置,放在No matter how,或者However 之后...although后面要跟主語？也可以是exciting though movie may吧？the moment i ()him i realized that something wrong()應(yīng)該填see,happen的什么形式？求詳細(xì)的講解。如果僅僅表語前置， 那就是：Exciting as (或者though) the movie may be,we have no time to see it 讓步句中表語置于句首時(shí)， 只能用as 或者although, 不能用其它從屬連詞再如：Young as / though he is, he knows a lot of things= Though/ Although he is young, he knows a lot of things. (注意， 這里不可以用as)as 作“盡管” 講， 引導(dǎo)讓步句時(shí)不能放在句首。 必須表語前置（放在第一位） the moment i (saw )him i realized that something wrong(had happened)realized 一詞已經(jīng)提示是過去， 所以都用過去時(shí)態(tài)， 由于happen 是在謂語realized 之前發(fā)生的， 屬于“過去的過去”， 所以用【過去完成時(shí)】we had hardly left the building ()it fell down.這里面hardly...when...就沒有用一樣的時(shí)態(tài)啊，這也是一。。。就。。。的意思啊，不太懂了，如果hardly表示幾乎不的意思的話，那為什么不填after,before呢？如果有The moment, as soon as,before, after 等連詞， 可用一般過去時(shí)代替過去完成時(shí)， 如果用Hardly....when.... 該用什么時(shí)態(tài)必須得用什么時(shí)態(tài)。 這是習(xí)慣。we had hardly left the building (when)it fell down=As soon as we left the building, it fell down.=The moment we left the building, it fell down
