写作思路：可以将网上购物的优点和缺点都详细地介绍一下，先说一下优点，比如网上购物非常的便利，不必浪费大量精力和宝贵时间等等；再说一下缺点，比如无法亲自试穿，纯在受骗的可能性。
正文：
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.
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.
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.
翻译：
随着互联网的发展和计算机的普及，网上购物已经成为我们生活中的一个普遍现象。在这里，消费者几乎可以买到他们需要的所有东西。
网上购物有很多优点，其中最重要的也许是它的便利性。人们不必浪费大量精力和宝贵时间从一家商店到另一家商店去选择他们喜欢的商品。
这对于不能亲自去商店的老人、病人和忙碌的人来说尤其可取。这些商品在网上有各种形状、大小和颜色。他们所需要做的就是坐在电脑前，点击鼠标。他们订购的商品将迅速送到他们手中。
然而，网上购物也有它的缺点。第一个缺点是消费者看不到商品或无法亲自试穿。有时，真正的商品可能与他们在电脑上看到的不一样。
第二个缺点是互联网上的一些商店没有注册。他们从你那里拿到钱后，再也不会给你送东西了。一旦上当受骗，你会发现你无处抱怨。
