英语.Our school has changed greatly in the past several year.同义句
Our school has changed greatly in the past several year. There (   )(   )great changes in the past several year.有人说是 have been .不是there 后面一般不用have么.

答案就是 have been
There be句型
当完成时的时候 be就变为have been 了
同样地 将来时就为 there will be 我相信 这个你听该见过吧.
这么晚了,楼主还不睡啊?好勤奋啊

there be是常见句型, 但其实此处也是这个句型,只不过be动词的形式是have been,为的是适应当句时态 现在完成时。 In the past several year是用完成时的标志。
