【正确答案】正确答案： Urbanization refers to the process of rural people migrating into cities. A key index of a nation's urbanization level is the distribution of its population in rural and urban areas. In the last year, the urbanization rate of China was over 50%, which marks that China has stepped into a new "city-based society". Urbanization has become an important part of China's social and economic development. By offering better education and more job opportunities to urban residents, it not only improves their living standards, but also enriches their cultural experiences.

【答案解析】解析：1．第1句中修饰“过程”的定语“农村人口向城市迁移的”较长，可译为that引导的同位语从句that rural people migrate into cities，也可以译为介词短语of rural people migrating into cities，作后置定语修饰“过程”。 2．第2句中的“衡量一个国家城镇化水平的一个重要指标”如逐字对译为a key index measuring a nation'surbanization level，译法刻板。“……的一个重要指标”，可处理成名词短语的形式a key index of…,表达地道且通俗达意。 3．仔细分析可发现，第3、4句之间逻辑关系紧密，第4句句首的“这”指代的正是第3句中的内容，故第4句可译为which引导的非限制性定语从句。 4．最后一句中含有三个谓语动词，“提供……机会”、“提高……生活水平”以及“丰富……体验”，后两者是“不但……也……”的并列结构，可用not only．．．but also．．．来表达。而“提供……机会”可看作是“提高人们的生活水平”的方式，故可用By引导介词短语作状语，表达为By offering better education and more jobopportunities。
