Water is the source of life.
We can do a lot to protect water.Let’s take action!I believe we can do it!
有没有语法错误？提提修改意见

Answer 1

先看看语法~
Last week ,I saw a people wasting water in the restroom.
people是复数，person才是单数。
→Last week ,I saw a person wasting water in the restroom.

I was very angry and I warn her not to do this next time.
你前面用了过去式，可是忘了后面的哦~
→I was very angry and I warned her not to do this next time.

Don’t throw litter into river.
river前面没有冠词，或者加复数也行
→Don’t throw litter into rivers.

从文章上来说~
We shoud save water.And we mustn’t pollute water.Don’t throw litter into river. Water is the source of life.
We can do a lot to protect water.Let’s take action!I believe we can do it!
这段你没有觉得怪怪的么……怎么也应该是先说We can do a lot to protect water，才举可以怎样做的例子吧~而且例子的内容也有点单薄了恩~结尾再有深度一点~~

那个~逻辑关系最好在紧密一点，因果关系什么的再强烈一点。
比如说多用点连接词，像什么as a result of, for example, from my perspective, as far as i am concerned, 之类的恩~

顺便说一下，写作文的话，用一些从句会更能丰富你想表达的意思……
单词什么的最好在多样化一点~不能说要表达污染的意思就光用pollute吧~还有contaminate、taint之类的恩~~

加油加油~要把学过的东西用起来才行~

Answer 2

.I was very angry 这里有个固定句型是be angry with。。。写作文时不能汉语化思维，动笔写句子时要本能想到固定短语··就不会发生汉语化现象，you see someone not protecting water
see sb. do sth.: 看见某人做某事
see sb. doing sth.: 看见某人正在做某事，你所强调的是一个现象，不是how,怎样浪费的，你用not protecting强调的是整个过程··你写议论文，还是换成see sb do sth。。还有··你作文写的不太美哦··句子之间连贯性不太好··

Answer 3

第二行still后面不是not 而是don't 哦．
第四行的someone 后也是一样的哈
整篇文章的人称要尽量一致，第四行的you最好换成we，使前后一致
第五行应为rivers
最后改为take actions.
最后一句最好用I bilieve we can make it!
加油！呵呵～～
