Reading Makes a Full Man

Reading is very important in our life. We can get more knowledge through reading. It can not only open our eyes but also make us wiser and richer in life. Besides, reading is also one of the most important ways to learn a foreign language like English.

I like reading newspapers and magazines because I can get lots of fun and learn about what’s going on around the world. Summer vacation is coming. I plan to do more reading. I’m going to read more classics to improve my language skills. I’m sure reading can make a difference to my life.

Reading makes a full man! Let’s start reading now.
