There be 结构中的名词提问可否保留 there?What 后的be 动词能用are?

1.What's in the tree?这个对.there be 句型后面加名词,名词不管单数、复数还是不可数名词,对整个名词成分提问就得用“What's ...+ 介词短语?”这种句型.对“What's ...+ 介词短语”的回答,得这样：单数,用There's ....复数,用There're ....there 一定不要了,不可用are ,得用is.朵颐答案是对there be 句型中的名词前面的数量词提问时,该用How many ...这种句型.我答得这么详细不知道你明白了吗?English is becoming more and more important.I think you're a student of Grade One,I hope you should spend more time in learning English .OK?
