Question

帮忙看一下有没有什么语法错误
Why do we need a clean environment
Firstly,we all need fresh air to breath,so,we need a clean environment.If the environment was polluted,then we can’t have fresh air.
Secondly,we need clean water to drink,if the environment is not clean at all,the water will be dirty.
Thirdly,if we live in a polluted environment,we can’t keep healthy.

Answer 1

Firstly, we all need fresh air to breath, so, we need a clean environment. If the environment 不过这句话里的so 后面就不需要逗号了 用逗号的话可以用therefore
If the environment was polluted, then we can’t have fresh air
这句的was改为is会好一些
所有的If引导的条件状语从句 后面的应该用将来时
呵呵 希望能帮到你～
