参考答案

正确答案:C
49.C【命题目的】此题考查考生对细节的理解能力。【解题要点】根据文章第三段第一句“Bacteriacannotbedetectedbe-causetheydon'tproducebadodororchangethecolor...”可见,食物有没有细菌,只靠看或者是嗅是没有用的。A错误。根据本段第四句“Ofcourse,freezingfoodslowsorstopsthegrowthofbacteria...”可见,全真模拟试卷(3)参考答案及精析第12页(共18页)冰箱里的食物其实也不一定安全,因为把食品冷冻可以放慢或使细菌停止生长,但不会彻底消灭细菌。B错误。根据本段倒数第四句“Bacteriacannotbetotallydestroyed...beforethefoodisthoroughlycookde”可以看出,除非食物彻底煮熟,细菌才有可能被破坏。所以C项正确。D项意为“在食物解冻之前吃”,根据常识,此项不合逻辑。故正确答案为C选项。
