单选题 7.  The students of this university complain about traffic noises which ______ them when they are having classes.
【正确答案】 A
【答案解析】 词汇题,考查动词辨析。disturb意为“打扰”;interrupt意为“打断”,如:interrupt a conversation(打断谈话);prevent意为“阻止”,常用于短语prevent...from中;interfere意为“干涉”,是不及物动词,常与with连用。本题有一定难度,需要用心体会各选项的用法。
   这所大学里的学生们抱怨说,交通噪音过大,干扰了他们上课。
