[单项选择] When global warming finally came, it stuck with a vengeance (异乎寻常). In some regions, temperatures rose several degrees in less than a century. Sea levels shot up nearly 400 feet, flooding coastal settlements and forcing people to migrate inland. Deserts spread throughout the world as vegetation shifted drastically in North America, Europe and Asia.

The adaptation was farming: the global-warming crisis that gave rise to it happened more than 10,000 years ago.
As environmentalists convene in Rio de Janeiro this week to ponder the global climate of the future, earth scientists are in the midst of a revolution in understanding how climate has changed in the past — and how those changes have transformed human existence.

[简答题]
城镇化是中国现代化进程中的一个基本问题。
推进城镇化需要产业支撑。在欧美、东亚一些国家和地区，由于协调了城市化和工业化发展，实现了现代化。而在拉美、东南亚一些国家，现代化进程出现反复或停滞，一个重要原因是在城市化过程中产业没能跟进，就业问题解决不好，甚至出现了城市贫民窟（指最恶劣的住房条件、最不卫生的环境、犯罪率和吸毒盛行的穷人避难所）等社会问题。
2012年，时任国务院副总理的李克强说，我到欧洲去访问，对方担心这样那样的问题，但只要跟他们讲中国的城镇化前景，他们就会兴奋不已，觉得中国的市场实在太大，有合作的机会。如果只跟他们讲产业，讲中国要加快哪些产业的发展、提高哪些产业的层次，他们就觉得是在与他们竞争，甚至会琢磨怎么搞反倾销来限制我们。
结合材料，运用《政治生活》的知识，分析中国应怎样打消欧洲国家对中国发展的疑虑，并说明这样做的政治意义。
