单选题 In speaking, the choice of words is of the utmost importance. But too often careless use of words ______ a meeting of the minds of the speaker and listener.
A. stirs B. prevents
C. destroys D. offers

【正确答案】 B
【答案解析】[解析] stir“搅拌，搅动；激动，轰动”和offer“主动提供”显然不合题意．而destroy“破坏，毁坏”是相对已存在的事物而言，所以只有prevent“防止；阻碍”是正确选择。
