It was my grandfather who bought the instrument many years ago.
问题描述：
It was my grandfather who bought the instrument many years ago.
书上是这么写的,感觉怪怪的.能不能写成：
It was my grandfather bought the instrument before many years.
答
这样的改写是不对的.原句是强调句型：it+Be动词+事物（被强调的人或者物）+that(who)+动词.原句可以翻译成：是我的爷爷多年前把那个乐器（仪器）带回来的.在这句话中,使用强调句是为了强调这个乐器是爷爷带回来的,主要强调人是爷爷.
原句可以改写为：It was the instrument that was bought by my grandfather many years ago.但是句子的味道就变了,变成了对那个乐器的强调.
当然原句也可以不用强调句型,直接陈述也是可以的：My grandfather bought the instrument many years ago.显然,此句式没有原文精彩了.
