句子There were hundreds of people there .改写成Hundreds of people were there.
如果不可以,为什么?如果可以,两个句子有什么区别

两句的意思不一样：
There were hundreds of people there.那里有好几百人.
Hundreds of people were there.好几百人在那儿.
应该改成：It has hundreds of people there.
再问： it 是代替的哪个词？
再答： it代指there
再问： 那后面的there岂不是多余的吗
再答： 不多余。没有there，意思又不一样了。 It has hundreds of people there. 那里有好几百人。 It has hundreds of people. 有好几百人。这种情况下，It可能是学习，公司，等等，无法特指“那儿”
