每日一词学英语(83): sidestep

今天是人类首次登月（Neil Armstrong，79岁）40周年纪念日，人类最后一次登月（Eugene Cernan，75岁）距现在已经37年了。包括Cernan在内的很多登月宇航员都建议美国政府考虑开展新一轮空间探索行动，把目标对准火星或更远的星球。（From Times Online, July 20, 2009: Apollo astronauts lament America's lost ambition）

Sidestepping the debate as to whether Nasa should instead be looking to Mars and beyond, the man who took that "small step for man" 40 years ago, instead reflected on the history of the space race. Armstrong回避了关于空间探索的争论，转而思考空间竞赛的历史。

“sidestep”释义：
1. to avoid answering a question or dealing with a problem 回避问题
*Did you notice how she neatly sidestepped the question?
*He sidestepped the issue by saying it was not his responsibility.
2. to avoid sth, for example being hit, by stepping to one side 躲避打击
