【正确答案】Low-carbon economy is a kind of economic mode of realizing sustainable development on the basis of environmental protection. At present, an increasing number of countries are making the transition towards low-carbon economy. China is no exception. In the past, China's economic growth was mainly driven by high-energy and low-cost manufacturing. In recent years, the growth has also destroyed the environment. To achieve the sustainable development, the government has promised to take concrete actions to develop low-carbon economy and protect the natural environment.

【答案解析】 1．第1句的主干是“低碳经济是经济模式”。翻译难点是如何表达“经济模式”之前的一串长长的含有介词短语和动词的定语。可考虑两种处理方法，第一，把“实现可持续发展”转换成介词短语of realizing...，作为economic mode的后置定语，“在……基础上”译成on the basis of...放至句末；第二，将定语转译成修饰economic mode的定语从句，即economic mode that realizes...on the basis of...。
   2．第2句中的“越来越多国家”可译成an increasing number of countries或more and more countries；注意本句表达正在进行的事情，因此应使用现在进行时。
   3．第3句“中国也不例外”，可单独译成一句，也可将其整合到上一句中，译成An increasing number of countries，including China，are making...。由于上下文的主题都是在讲中国的经济发展模式，故用前一种译法能更好地与上下文衔接。
   4．第4句的主干是“发展模式是……”，故可译成带表语从句或同位语从句的句子，即In the past，China's economic pattern was that...，或In the past，China followed the economic pattern that...。或可适当地减译“发展模式”，译成China's economic growth was driven by...，也能清楚表达文意。
   5．第5句为汉语中的无主语句，没有明确的主语，翻译时有两种处理方法：第一，译成被动句，即the environment has been destroyed along with the economic growth；第二，将状语“在经济增长的同时”中的“经济增长”处理为英文句子的主语，即the economic growth has also destroyed the environment。
   6．最后一句中的“为了实现……发展”为目的状语，故译为不定式短语置于句首。句末的“发展低碳经济，保护自然环境”是“采取行动”的目的，可处理为并列的不定式。
