为什么是：We have planted ten tress and there are twenty more to be planted
为什么不能是
there are twenty more to plant

sth.to do 是要干某事,这件事是由主语来做的,而sth.to be done是有事要做,这件事本质上不是由主语来做的．
比方说：I have my dinner to cook.这里的饭是我做的,而I have my hair to be cut.头发不是我来剪的,是理发师,但我要剪头发.
你这里的to be planted 的主语是there,所以应该用to be done.

为什么是：We have planted ten tress and there are twenty more to There are twenty more trees to be planted.There are _______ 有这样一句话:There are twenty more trees to be planted.那么这一句呢: More and more tress will be planted in order to protect crop 英语翻译At twenty to ten,we have a b___ for twenty minutes. 英语翻译There’s a lot more to be done,and we are not going to mi There are twenty more trees to be watered.的同义句 There are tre there are more important things we have to know which teache They planted one h_____ trees yesterday. There are more than We have ten fingers and ten f______ There are more and more people是加to do 还是doing? There are more and more (tour)_______coming to Shanghai thes
