If it doesn't rain within the next few weeks ,the crops

Question

If it doesn't rain within the next few weeks ,the crops will have to be watered if they are to be survived
这句话中有一处错误（if they are to be survived）是这一处吗
是的话错在什么地方呀！！！！
这句话什么意思呀）

Answer 1

if they are to be survived错的

应该改成if they are going to survive

如果在下几周内不下雨,这些庄稼需要浇水,如果想让他们活的话

Answer 2

survive 活下来的意思.
用被动语态不行,成了什么东西将要被活下来.

话的意思是,如果近几周内不下雨,我们就要给这些庄稼浇水,否则他们就死了.本回答被网友采纳
