At present only a few students do some reading after class£®Here are several reasons£®
First of all£¬quite a lot of students are burdened with too much homework£®Still others haven't formed a habit of reading£®They would rather spend their spare time on TV or on the Internet£®
However£¬reading has many advantages£®Through reading we can learn more about the world£®Besides£¬it can help us think better£®Reading can make our life more colourful£®
Here are my suggestions£®For one thing£¬teachers are supposed to limit the amount of our homework so that we can have more time to read£®For another£¬it's a good idea to form reading clubs and learn from each other£®£®
