Scientific China Monthly, founded in 1937, is a popular science periodical in the Republic of China. It was republished in Shanghai in 1946 following the Anti-Japanese Aggression War. Articles in the regular column “science news” were translated from famous popular science periodicals in the United States, such as Popular Science, and Popular Mechanics, etc. This paper focuses on 210 pieces of science news from 1946 to the founding of the P. C. China, 41% of which were selected from Popular Science's “science news”, “science at work” and “PSM features”, etc. Through an acomparative study of the translated text and the original versions, it is found that the translation selection strategy of science news is affected by many factors, such as public interest, popularization, readability, as well as practicability and easy to read or not. Under such circumstance, it had to give up some important, cutting-edge and hot science news, which is contrary to the purpose of the news, however, it was a no-other-alternative choice in such social settings.
