With the development of the Internet and the popularization of computers, shopping on the Internet has become a commonplace in our life. Here consumers can buy almost everything they need.

隨著因特網的發展和計算機的普及使網上購物在我們的生活中日漸普遍。在這里消費者幾乎可以買他們需要的所有東西。
Shopping on the Internet has a lot of advantages, of which the most important is perhaps its convenience. People don't have to waste a lot of their energy and precious time to go from one shop to another to choose the commodities they like. This is especially desirable to the old, the sick and the busy people who cannot go to the shops in person. The goods come in all shapes, sizes and colors on the Internet. All they need to do is to sit in front of their computers and click the mouses. The commodities they order will be delivered to them promptly.

網上購物有很多優點，其中最重要的也許就是方便。人們不必浪費太多的精力和寶貴的時間去從一個商店到另一個來選擇他們喜歡的商品。對于老人病人和忙碌的人來說是特別可取，因為他們不能親自去商店。互聯網上的商品有各種形狀，大小和顏色。他們所需要做的就是坐在電腦前，點擊鼠標。他們訂購的商品將會及時的送給他們。

However, shopping on the Internet also has its disadvantages. The first disadvantage is that the consumers can't see the goods or try them on personally. Sometimes, the real goods may not be the same as what they have seen on the computer. The second disadvantage is that some shops on the Internet are not registered. They will never deliver anything to you after they get the money from you. Once cheated, you will find that you have nowhere to go to complain.

然而，網上購物也有它的缺點。第一個缺點是消費者不能看到商品或親自試一試。有時候，真正的商品可能會和他們在電腦上看到的不一樣。第二個缺點是有些互聯網上的商店是沒有注冊的。從你身上得到錢后他們不會給你送任何東西。一旦被騙了，你會發現你無處可抱怨。
