an easy english problem

问题描述:

an easy english problem
I wonder if scientists trying to learn about the sea floor,they would also face similar problems?
为什么用trying啊,应该用原型吧.
是不是加上are或者改为原型都行啊?

if 引导条件状语从句,主句一般将来时,从句一般现在时
所以这句话应该是:I wonder if scientists are trying to learn about sea floor,they will also face similar problems?
