At present,only a small number of the students often read after class.They often have too much homework to do so they don't have time to read.Also,some of them don't have the habits to read after class.So they don't read after class very usually.
But reading after class has many advantages.First,students can know more about the world through reading.Besides,reading can also teach them how to think about themselves and other things.Last but not least,reading can make their lives more colorful.
So I think reading after class is as important as reading text books.We should not just read text books,we should also read after class.
