I go online as often as I can. First of all, I can shop on the Internet without leaving my room. When I shop on the Internet, it takes me only about half an hour to find what I want. Second, I can send photos to people anywhere in the world in less than five minutes just at home. The most important reason for me to go online is to keep in touch with my friends and the people who are important to me. Going online has become an important part of my life. For me, it’s a bridge that connects me to any place I like.

参考译文如下：

我尽可能经常上网，首先，我能不出门就可以在网上购物，当我在网上购物时，找到我想要的东西所花费时间仅仅大约1个小时，其次，我能在家里花费不到5分钟时间就能把照片发送到世界上的任何地方，我上网的最重要原因是和我的朋友们以及对我很重要的人保持联系。上网已经成为我生活中很重要的一部分，对我而言，它是连接我和我喜欢的地方的一座桥梁。
