Answer 1

分析 意识到老龄化问题带来的破坏性后果，当地政府鼓励年轻夫妇们生育二胎，这给奶粉市场带来了生机．

解答 答案：Realizing the damaging consequences caused by the aging problem，the local authorities encourage young couple to have a second baby，which brings energy to the powder market．考查which引导的非限制性定语从句．
句子里Realizing the damaging consequences caused by the aging problem是现在分词做原因状语，其中caused by the aging problem是the damaging consequences 的定语；which引导的非限制性定语从句，代指主句．

点评 考查汉译英．
非限定性定语从句的作用是对所修饰的成分作进一步说明，通常是引导词和先行词之间用逗号隔开，将从句拿掉后其他部分仍可成立
which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分
例如：Earlier，the Babylonians had attempted to map the world，but they presented it in the form of a flattened disc rather than a sphere，which was the form adopted by Ptolemy．
（此句中，非限定性定语从句是对先行词a sphere进行补充、说明．）
