支付宝(Alipay)是中国最大的第三方在线支付平台，由阿里巴巴集团(Alibaba Group)于2004年创建。截至2012年底,支付宝拥有用户超过7亿。用户可利用这一平台支付各种费用，诸如网购、电话费、学费等等。以网购为例，买家先将钱存到支付宝账户，收到商品后，再通过支付宝将钱转给卖家。支付宝为其用户提供了“简单、安全、快速”的在线支付方式，保护了买卖双方的利益。

Founded by Alibaba Group in 2004, Alipay is China's largest third-party online payment platform. Alipay has over 700 million users by the end of 2012. Users can pay various bills via the platform, such as online shopping, telephone bills, and tuition fees. Take online shopping as an example. Buyers put the money into their Alipay account which will not release the money to the sellers until the buyers get their goods. Alipay provides its users with a simple, safe and fast online payment method, protecting the interests of both buyers and sellers.

1.第1句如果用并列结构逐字对译为Alipay is China's largest... and was founded by...则因时间逻辑关系(应先创建才能成为最大)而不符合英语表达习惯，故可将“由阿里巴巴集团于2004年创建”处理为状语，译为Founded by Alibaba Group in 2004，置于句首。

2.第3句中的“用户可利用这一平台支付各种费用”如直译为users can use this platform to pay all kinds of bills则显生硬，翻译时可用介词via来表达“利用”，译作users can pay various bills via the platform,使句子结构简洁明了。

3.第4句中的“以网购为例”意思独立完整，可单独译成一个句子Take online shopping as an example。

4.第4句中的后三个分句有三个动作“存钱”、“收货”和“转钱”，如果按照原结构翻译成英文，译文会比较繁冗平淡，故可考虑对句型结构进行重新整合，将“买家先将钱存到支付宝账户”作为句子的主句，而“转钱”这一动作的执行者可看作是“账户”，故后两句处理为which引导的定语从句，“收货”和“转钱”的先后关系可用 not... until 来表示。本句也可译为 Buyers do not transfer their money, which is put into Alipay accounts in advance, to the sellers until they get their goods。

5.在最后一句中，“为其用户提供了”可套用providesb. with sth.的结构;“保护了买卖双方的利益”可处理成表结果的状语，用分词短语protecting the interests of both buyers and sellers 来表达。
