这个表达法是错误的，应该这样翻译:by shopping online这里by是介词，后面跟动名词短语shopping online，整个构成一个介词短语，在句子中可以充当方式状语。

Online shopping is popular nowadays. It is easy, fast and convenient. Take JD for an example. I place an order in the morning, it reaches the destination in the afternoon. Online shopping saves time and money on transportation. But it also has some disadvantages. We will have to provide our address, telephone number and even bank account with the online shop owners. In other word, we may expose ourselves to unknown dangers. So the only way is to be cautious to online shopping. Choose the reliable online shop owners with good reputations only.今天网购很流行，它既方便又快捷。比如说我上午在京东网上订一个东西，下午就到了。这样就能节省花在交通上的时间和金钱了。但是网购也有些不利之处。比如说我们需要向商家提供地址、电话甚至银行账号。换句话来说，我们可能将自己暴露在潜在的危险之下。所以网购的时候只能小心谨慎。选择那些声誉较好值得信赖的商家。
