【正确答案】正确答案： After over 30 years' development, China's express delivery industry has already grown into a large-scale industry. According to statistics, the number of express delivery enterprises has exceeded 5,000 with a staff number of 300,000. Currently, express delivery circles centered on the large cities in the coastal area of east China have formed. There is a tendency of diversification in express service, with state-owned, private and foreign express delivery companies existing and competing with each other. The rapid development of China's express delivery industry is closely related to the development of e-commerce. It is predicted that its revenue will exceed 400 billions Yuan by 2020. By then, the express delivery industry will create more than 350,000 new jobs for the country and hire a total of 1 million employees.

【答案解析】解析：1．第一句有两个谓语动词“经过”和“形成”，在翻译时可译为并列句has experienced…and grown into，也可以像参考译文将“经过30多年的发展”作为状语处理。 2．第二句“快递企业已达到了5000余家”，可加译number一词，即快递企业的数量；“员工人数达30万人”则可使用with引导的介词短语来表达。 3．在“中国东部地区已经形成了以沿海大城市为中心的快运速递圈”中，“中国东部地区”可理解为地点状语；可把“快运速递圈”理解为主语，谓语为“形成”；“以沿海大城市为中心的”作主语“快运速递圈”的后置定语。 4．第四句中的“快递服务呈现多元化趋势”可理解为“快递服务有多元化的趋势”，使用there be句型表达；“国有、民营和外资快递公司共存，相互竞争”处理为with引导的独立主格结构，state—owned，private and foreign express delivery companies为“共存”(existing)和“竞争”(competing)的逻辑主语。
