Connect to the world
Over the past 20 years, the Internet has greatly influenced our world and    our lives. The Internet makes it much  for people to search for information. For   , when we write a history report, we don’t have to go to the library. We can find    about world leaders and historical events on different websites. Everything we want to know can found at the click of a button.
The Internet helps us to stay connected to family, friends and the world around us. Not long ago, we wrote letters and waited weeks for a reply. Today, when we use QQ, we send and receive messages across thousands of miles in a   seconds.
Although the Internet has made our world better in many ways, in some    it can be a bad influence. There is a lot of false information on the Internet. It is important not to believe    we read on the Internet.
Some teenagers spend too much time   Internet games. They may lose focus on their studies.
There are millions of interesting sites to visit and so many wonderful things to do online. How could we live without the Internet nowadays? But try to let the Internet be your   servant, not your bad master!
