Write a composition according to what you have discussed about.
With the help of the Internet,shopping is not a difficult job.Just clik your mouse to choose the article you like,and the shopping is finished.You needn't step out of the room.It seems easy and quick.
But there's always a trap(n.圈套）online.If you are careless,it will bring you some trouble.You may find the color of the article is different from what you want,or the size is either too small or too big.
If you want to be different,you'd better not buy clothes online.Once you put on the clothes you bought online and go out,you may find many people wear the same clothes in the street.
Homework
