题目

一篇英语文章,帮我看看有没有 语法错误.
every time you should study hard whatever happened.
you should know when you come to class what your dreams are,known what you should do.
three years can be very short,but what can be remained?Are they regret,disappointment or joy,happiness?
Have you ever thought about how strange it is.someone wastes his time while someone studies hard.it's not a joke.when you laugh and hang out with your classmates,have you ever thought about your parents,teachers and yourself.we often complain about how short the time is.but how much time we really get good use?the answer is little.
time goes by.our time reduces little by little.and we also can do something to change our situation.there are some examples,during the school days,we can keep away from the mobile phone,MP3,MP4,MP5 and so on.it's important to learn give up something which is bad for us at present.
in the end.one thing you should know is that we may try and try so hard but we can't get a good result.it's unfair,but what fair is?
never give up.the people in China are hard-working and brave with 5000 years' civilization.
we all have a dream,so spare no effort to study.next test is coming.go on.
我准备写我同学的.

答案

虽然是中文式翻译,不过只要没有大的语法错误,也没有什么.
1.Anytime you should study hard whatever happens/happened.
2.you should know when you come to class what your dreams are,known what you should do.语法没什么错误,只是我们通常是把状语放句首或句末.when you come to class,you should know what your dreams are,know what you should do.
3.laugh at hang out with 介词不一致,是不能省的.
4.make good use of
5.learn to give up
