【正确答案】①For China, proposing the Belt and Road Initiative (BRI) is a natural step as its economy enters a new stage. It helps address China's own problems of imbalanced and unsustainable development. It is also an important measure in China's new round of opening up. ②BRI follows the principles of extensive consultation, joint contribution and shared benefits. These principles are in line with China's foreign policy which advocates peaceful development and win-win cooperation. BRI is an important effort in building a community with a shared future for mankind. ③In the past five years since it was proposed, BRI has been warmly received around the world. It is now the world's most popular public goods and largest platform for cooperation. ④More than 150 countries and international organizations have signed agreements with China on BRI cooperation. ⑤For higher goals in building BRI, we will do our best to make the second Belt and Road Forum for International Cooperation a success. We will also push for progress in a series of key projects. These will ensure higher quality and higher standards in BRI development.

【答案解析】1．①句由四个分句组成，第一个分句总说中国提出“一带一路”倡议，后面三个分句则解释该行为的性质，翻译时可以采用拆译法。按照意群划分后，将其译作几个单独的句子，同时除第一句外，其他几个句子的主语都由指示代词it(指代“提出‘一带一路’”)代替，以此加强句子间的逻辑联系。 2．①句中“是中国经济发展到新阶段的必然选择”，其中“中国经济发展到新阶段”是“一带一路”倡议提出的时间背景，翻译时显化这层逻辑关系，添加引导词as，译作For China, proposing the Belt and Road Initiative (BRI) is a natural step as its economy enters a new stage。 3．②句中“这既符合中国和平发展……”，其中指示代词“这”指代的是前一句中的共商共建共享原则，翻译时根据需要补充信息，译作These principles are...，使译文的意思更加清晰。 4．②句“这既符合中国和平发展、合作共赢的外交政策”中“和平发展、合作共赢”属于中心词“外交政策”的修饰语，由于定语较长，翻译时可以使用which引导的定语从句，译作These principles are in line with China's foreign policy which advocates...，更加符合英语的表达习惯。 5．③句中“得到世界各国普遍欢迎”，可以按照原文的结构处理成the Initiative has gained worldwide recognition，也可以采用被动语态转换法，译作BRI has been warmly received around the world。 6．⑤句“更高质量、更高标准、更高水平”中的“更高水平”表意比较宽泛，“水平”指“在某一方面达到的高度”。在前面已经有“更高质量、更高标准”的情况下，“更高水平”语义上显得赘余，“更高质量、更高标准”实际上已是“更高水平”的表现。因此翻译时可以略去不译。
