误译：Some people think bulk buying can really change the way we shop.

　　正译：Some people think team buying can really change the way we shop.

　　解释：“团购”需要“众多零散消费者”、“较低价格”和“大批量”等三个因素。bulk buying具有“大宗采购”的意思，只涉及“ 较低价格”和“大批量”等两个因素，而不管购物者有多少人，买主可以是个人，也可以是群体。team buying 包含上述三个因素， 为“团购”的正确译法。

　　1. 大多数已发生的大宗采购是由个人投资者进行的，他们在寻求巨大的投资机会。 Most of the bulk  buying that's been happening is being done by individual investors, who are seeking great investment  opportunity.

　　“团购”的意思是“将具有相同购买意向的零散消费者集合起来，向厂商进行大批量购买的行为”，即“团体购物”。译为team  buying, team purchasing, group buying,group purchasing, group purchase。例如：

　　2. 团购已给中国的网络购物增添了新的内容。Team buying has added new dimension to China's online shopping.

　　3． 团购是网络购物的一种新方式，它在年轻人中 间变得越来越流行。Group purchasing is a new way to buy things on the Internet, which is becoming more and more  popular among young people.

　　“网络团购”，译为team buying on the Internet, group buying on the Web。例如：

　　4. 尽管网络团购的出现只有两年多时间，却已成为在网民中流行的一种新消费方式。Although it has been only two years since the emergence of team buying on the Internet, it has become a new way of consumption popular among the netizens.
