为什么用brought而不用had brought
it's a good thing that i_ a raincoat,otherwise i'd have been wet all over为什么用brought而不用had brought
brought是一般过去时,had brought是过去完成时,表达的是一个在“过去的过去”发生的动作.用过去完成时的时候必须有一个过去的时间或动作作参照.如:I had learned 2000 English words by the end of last month. by the end of last month是“到上月末为止”的意思,“上月末”是个过去时间,learned 2000 English words发生在上月末之前.是“过去的过去”. The train had left when we got to the station.我们到车站的时候火车已经开走了.got to the station是过去的动作,而 train had left 发生在 got to the station之前.
由otherwise i'd have been wet all over可以看出这是个与过去事实相反的虚拟语气。I bought a raincoat 是个发生在过去的动作,不需用虚拟语气,所以只能用bought。如果是这个句子的话,就用had bought。If I hadn't bought a raincoat,I would have been wet all over.
