国外有研究表示，通过名字姓氏可以透视购物意愿，来帮助销售。今天，北京新航道托福频道要和大家分享一篇托福课外阅读：姓氏效应，在阅读中不断提神自身能力，一起看看去吧。

　　According to a new study, people whose surnames start with letters late in the alphabet may be the fastest to buy. What could possibly explain this weird phenomenon, which the study authors dubbed "the last-name effect"? The research didn't provide a definitive reason, but the authors offer an intriguing theory.

　　Since America's obsession with alphabetical order often forces the Z's to the back of the line in childhood, they suffer.

　　因为美国人一直热衷于按照字母顺序排队，所以姓氏字母靠后的人从小就开始遭受排在队尾的境遇。中午吃饭的时候，他们总是排在最后，轮到他们的时候，巧克力奶都卖光了;坐在教室后排的他们还得想办法吸引老师的注意。所以，长大以后，当这些总是排在队尾的人看到他们喜欢的东西或者合适的交易，他们会立马出手，生怕晚了就没了。
