单选题 The elements of nature must be reckoned with in any military campaign. Napoleon and Hitler both underestimated the______of the Russian winter.
【正确答案】 A
【答案解析】解析:四个选项的意思分别是severity“恶劣”;consequence“后果”;influence“影响”;threat“威胁”。句意是:在一切军事行动中,必须要考虑到恶劣的天气,而拿破仑和希特勒两人恰恰都低估了俄罗斯的严冬。所以正确答案是A选项,如with all the outward severity he is kind at heart(他虽然外表严厉,但心地和善)。
