credit [ˈkredɪt] v.
credit card在我们的生活中处处可见，你知道TA的故事来源吗？

He was shcked t discver that he had frgtten his wallet. T his embarrassment, he then had t call his wife and have her bring him sme mney. McNamara vwed never t let this happen again. 受到这次事情的启发，McNamara came up with a new idea — a credit card that culd be used at multiple lcatins. 他和朋友创办了“就餐者俱乐部”，顾客凭credit card可以在纽约27家饭店用餐而不需带现金，到时只要和就餐者俱乐部一次清账就可以了。通过这个故事我们可以看出，credit card 其实是与人的“信誉、信任”相关，也就是credit这个英文单词。
