One possible version:
With the development of the Internet, many people are used to shopping on line. It has become a fashion in our daily life. Some of us students also join the group.
Shopping on line has many advantages. Just by a click of the mouse, you can buy what you’re interested in without going outdoors. You can avoid getting tired and being trapped in the crowded people and cars and save time. When shopping on line, you can choose from more varieties of goods, whose prices are generally lower.
Every coin has two sides. Its disadvantages are obvious, too. On one hand, it’s very easy for you to buy goods different from the pictures you see on the Internet. On the other hand, shopping on line may cause people to buy goods that are not badly needed. That’s a waste of money.
All in all, I love shopping on line.
