来找找这篇英语文章的错误

Doing eye exercises is a good way to your eyes.So some school makes （应该是some schools make,既然用了some,后面当然要用可数名词复数形式,同时谓语也不能用三人称单数了.所以改为make）students do eye exercises after the （去掉the,after class,这里没有特指）class evry afternoon.But some people say it is not good to do eye exercises after the class.They think when class is over Students' hands are very dirty and there are a lot of germs.If they do eye exercises that time germs will attact their eyes and make their eyes dirty and not healthy.
In my opinion .(改成逗号)I think students should do eye exercises after the class.But when they finish the class,they should wash hands first and keep their hands clean.After that,they can do eye exercises.Eye exercises is a good way to protect our eyes.Let's do it and keep our eyes healthy.
其实,我觉得这篇文章没有很大的语法错误.只是,没有活用句型,所以显得呆板,而且没有新意.可能你是初学者吧.不过要好好努力哦.我帮你把文章改改,改成以下形式.（不过不要抄,自己学哦）
