Question

看一下，有语法错误没有

We have only one earth. But now,the environment becomes worse and worse.

As you know,there's no enough clean water for people. So many of them lose their lives because of water. In a lot of countries, people have to cut trees for living. So there's nothing to keep water from running away. Also we have polluted the land, the river and the air. So we have to face more and more floods and droughts .

It's time that we must do something useful to protect our environment. We can plant trees and take good care of them. We can save the water and ask our parents to do so. We can't throw any litter onto the ground and we should collect them for recycling.

If we take good care of our earth today,it will be more beautiful tomorrow.

Answer 1

这句话错了：It's time that we must do something useful to protect our environment.

应该是：It's time that we did soemthing useful to protect our environment.

It's time that 后面应该用虚拟语气。

no enough 最好是：not enough

Answer 2

第一段把but和,去掉。第三段 t's time that we did..

看完整篇，觉得废话词多，语句幼稚，简单句还硬套，明显是中文式的英文写法。

除非刚上初中还情有可原。

你，最好重写。

Answer 3

第二段，As you know 改成 As we know 固定习语，（众所周知）
