We usually buy things in a shop, a market or a supermarket. Shopping always takes too much t . We have to walk around for a long time to look f    the things we want. Sometimes we have to c  many heavy shopping bags. We’re always very tired after s  . Now it’s different from that in the past(过去). We can do many things at h   , we don’t need to go to the shop. We can buy many good and c     things on the Internet(因特网), they look nice but don’t cost much. It seems easy and quick, b    it sometimes brings us some trouble(麻烦). The clothes you buy on the Internet are d       from what you want, or the size is too
s    or too big. You may see many people wear the same clothes in the street. Do you know why? B   they all buy clothes on the Internet. How interesting!
