Lesson23 A new house 新居
I had a letter from my sister yesterday.She lives in Nigeria.In her letter,she said that she would come to England next year.If she comes,she will get a surprise.We are now living in a beautiful new house in the country.Work on it had begun before my sister left.The house was completed five months ago.In my letter,I told her that she could stay with us.The house has many large rooms and there is a lovely garden.It is a very modern house,so it looks strange to some people.It must be the only modern house in the district.
1:Work on it had begun before my sister left.(为何不用过去时,而用过去完成时.工程这里没有谈到结束啊?）
2：The house was completed five months ago.（这句为何用一般过去时被动语态?而不用过去完成时的被动语态?）

这个句子里my sister left是过去时,而work是在my sister left之前发生的,构成了过去的过去这种句式．所以用过去完成时.
过去完成时使用条件：一句话中必须有个过去的时间点,而且一件事情是在这个时间点之前发生的.所以过去完成时不能随便用.并且,这句话中有ago这个词,一般用一般过去时.
愚见：
1、既然该工程在my sister离开之前建，过去的过去则过去完成时
2、five months ago 是个明显的过去时态的标志
在我姐姐离开之前，工作已经开始了，是发生在过去的过去，所以用过去完成时。
看动词哦，complete完成是一次性动作，不能用来表示一段时间。所以用一般过去式。
