我写的一篇英语作文帮麻烦修改下，谢谢

the eyes of them改成their eyesigt他们的视力（eyes是复数，was是单数。搭配错误）
very very可改成so
nobody clean改成nobody to clean
every time改成each time（这是正常搭配）
Many teachers of school was not duty to us中was改成were（主语是老师们，谓语应该用复数)
duty to us改成on duty值日、在职
So many students’ grades was 改成many students' grades are all terrible
看不清黑板：they cannot watch the blackboard closely
如果我们开灯被学校发现就会罚款：if we turned on lights，we will be fined by our school
我好不容易打好的，希望同学可以认真看一下。其实英语学习还在于自己，加油！

can't look at blackboard clearly . if we turn on the light in the daytime ,we will be fined。
应该是there is no water ,so nobody clean。 So many students’ grades were very terrible amd they got Ds this term.
