“A horse runs faster after a rest”的意思
好像是个谚语吧...
原文:
Many people think the more time is spent ,the more work will be done.So students have to spend the whole day doing school work except the three meals.It is common to see students struggle in a sea of school work both at school and at home.
Modern students usually have many interests.They love music and sports.They like reading and watching TV.A two-day weekend can get them away from too much school work,and they can do what they like.But still teachers do not think about it.Because they have too much school work,they have no time to enjoy themselves.Students are really tired of their weekend homework.So they usually don’t do their weekend homework until Sunday night.And there is not enough time for so much work,so students have to finish it carelessly.The weekend homework makes teachers angry.
Too much school work makes students lose interest in learning.It’s also bad for their health.
A horse runs faster after a rest.But for students only rest is not enough.So such a condition should be changed to give students both pleasure and knowledge.
Please give students less homework but leave them more free time.
