改革开放是改变中国前途与命运的历史抉择，也是促进世界振兴和繁荣的伟大实践。

参考译文：Chinese leaders made the historic decision 40 years ago to carry out reform and opening-up which changed the course of China's future. Our efforts to implement that decision have contributed enormously to world rejuvenation and prosperity.

解析：这一句中文引自10日外交部发言人耿爽对记者提问的回答。这一句的英文并没有按字面意思来翻译，而是将“改革开放”这四个词的历史背景也揭示了出来。当然，就翻译本身而言，这句话也可改成如下：The reform and opening-up policy was a historic decision-making, changing the course of China's furutre. Also, it witnessed our great efforts contributing enormously to world rejuvenation and prosperity. 在此感谢所有提供译文的同学。
