问题 The tragedy could have been ______ if the crew had followed safety procedures,
选项 A、interfered
B、averted
C、intervened
D、distracted
答案B
解析 动词辨义。这四个选项都是动词，interfere表示“(常与with连用)干涉，干预；妨碍；打扰”，如：I don’t want to interfere with you；proceed with your work．(我不想打扰你了，你继续工作吧。)avert表示“(常与from连用)避免；防止”，如：Accidents can be averted by careful driving．(谨慎驾驶可避免发生事故。)intervene意指“插入；介入”，如：I shall leave on Sunday if nothing intervenes．(如果没有别的事，我星期天动身。)distract表示“(常与from连用)使…注意力转移；使分心”，如：The noise in the street distracted me from my reading．(街上的嘈杂声使我不能专心读书。)根据句意，如果遵守安全操作程序，悲剧是可以避免的，所以B)项符合题目要求。
