题目内容：

()the movie may be,we have no time to see it,为什么不能用although exciting,although一定要倒装吗?

优质解答

However exciting等于：No matter how exciting the movie may be,we have no time to see it.因为No matter how,或者However 是修饰表语 exciting的,所以必须得把exciting 前置,放在No matter how,或者However 之后...

追问：

although后面要跟主语？也可以是exciting though movie may吧？ the moment i ()him i realized that something wrong() 应该填see,happen的什么形式？求详细的讲解。

追答：

如果仅仅表语前置， 那就是： Exciting as (或者though) the movie may be,we have no time to see it 让步句中表语置于句首时， 只能用as 或者although, 不能用其它从属连词 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， 这里不可以用as) as 作“尽管” 讲， 引导让步句时不能放在句首。 必须表语前置（放在第一位） the moment i (saw )him i realized that something wrong(had happened) realized 一词已经提示是过去， 所以都用过去时态， 由于happen 是在谓语realized 之前发生的， 属于“过去的过去”， 所以用【过去完成时】

追问：

we had hardly left the building ()it fell down.这里面hardly...when...就没有用一样的时态啊，这也是一。。。就。。。的意思啊，不太懂了，如果hardly表示几乎不的意思的话，那为什么不填after,before呢？

追答：

如果有The moment, as soon as, before, after 等连词， 可用一般过去时代替过去完成时， 如果用Hardly....when.... 该用什么时态必须得用什么时态。 这是习惯。 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
