Wei Fang, a 15-year- ( http: / / www.21cnjy.com )old student from Sichuan, was preparing a talk on Western festivals. She looked for information online. Zhu Hui, her classmate, was doing his physics homework. But he couldn’t work out the last problem. So he took out his smartphone, opened a special app and looked for the problem. Solutions(解决方案) appeared on his screen after a few seconds.
Like Wei and Zh ( http: / / www.21cnjy.com )u, nowadays, many students do their homework with the help of the Internet. They look for information online, or discuss with their classmates through QQ and WeChat.
“It’s convenien ( http: / / www.21cnjy.com )t.

What’s more, it improves students’ problem-solving abilities. This is especially true for homework that needs some research work.21cnjy.com

problems. Some lazy st ( http: / / www.21cnjy.com )udents just copy the answers from the Internet without thinking on their own. Some even let their classmates do their homework for them. And their teachers may not know this.2·1·c·n·j·y
But knowing how to us ( http: / / www.21cnjy.com )e the Internet is important. The key is to have good self-control(自控). When you meet a difficult problem, think about it by yourself first. Be sure to understand the reasons behind the answers after you have turned to the Internet, or you won’t make any progress(进步). If you are not sure about your self-control, ask your parents for help.
