First, I’d like to thank you for your reminding, although I don’t agree with your view which students should spend more time on their lessons instead of read novels.Indeed, reading novels takes up some of the time that should spent on lessons, but it’ll make us know what hard life is.Besides, by reading novels we can gain what we can’t learn from our textbook.Of course, reading novels has it’s shortcomings.Novels that have wrong ideas will make us to do something wrong.Maybe, in your eyes, the disadvantages of reading novels outweighs the advantages.And in my opinion, reading novels is just as another pair of eyes, which broadens my horizon.
