There have been great changes in our country since 1990.
..有几个疑问：为什么 There 后面是 have 而不是has 还有为什么是great changes 而不是单数?我要的是为什么.

因为从1990到现在我国肯定是有很多变化而不是一个所以是great changes 而宾语changes 是复数所以谓语肯定也要用have 而不是单数形式has 可以用 there has been啊比如说 there has been a great dream in my mind sincen i was a little child.
