Dear Sir,

　　I think we have entered a card age. Just open a wallet, and we can see a lot of cards: credit cards, bank cards, public transport card, working ID card, perhaps student ID card, library cards and many types of shopping membership cards. I think it is just like what I overheard heard on the bus, cards are everywhere, and everything requires cards. How funny it is. After thousands of years of complex revolution and development, our daily life goes back to the simplest way—card usage.

　　The advantage of using cards is to make our life easier and tidier: credit cards save us from taking large sum of cash, and ID cards contain a lot of information about us. Besides, the cards are gradually becoming a new channel for advertisement, promotion and customer maintenance—in particular, shops are so keen on building up membership relationships with customers and keeping them shopping continuously with them.

　　However, with the wide usage of cards, some problems come out. Shopping with cards is still at the beginning stages, and not every shop provides such services, so cash is still necessary. When some cards are missing, such as credit cards, it’s likely to be quite messy, as the cards may be mis-used by bad people.

　　Anyway, cards do change our life for the better and I think we are in the age of cards now.

　　What do you think?

　　Yours，

　　Amy

　　我认为我们进入了一个卡片时代。打开钱包，我们会看到好多的卡片：信用卡、银行卡、公交卡、工作身份卡，可能还有学生身份卡、图书卡和很多商场会员卡。我想这就像我在公交上听到的那样，到处都是卡，所有的事情都需要卡。多有趣啊!经过几千年复杂的变革和发展，我们的日常生活追溯到最简单的时代——用卡时代。

　　用卡的优势是使我们的生活轻松和整洁：信用卡使我们可以不用带大量的现金，身份卡包含了大量的自我信息。除此之外，卡逐渐变成了一个新的广告、提升信誉并维系顾客的渠道。尤其是，商店们都很热衷于与顾客建立会员制而让其不断购买他们的商品。

　　然而，随着大范围对卡的使用，很多问题随之而生。商店使用卡尚处于初始阶段，不是每一个商店都提供这样的服务，因此现金仍然是有必要的。当一些卡片丢失时，就像信用卡，当被坏人拿到使用时间情况就有可能变得非常糟糕。

　　不管怎样，卡片让我们的生活变得更好了，同时我认为我们正处于卡片时代。

　　你们怎么看?
