B. chemicals are needed in food processing C. food poisoning can be kept under control
D. food poisoning is out of control 55. It can be inferred from the passage that ___. 55. C
推理判断题。由第五段When people handle food properly, the risk of food poisoning is very small(只要人们处理食物恰当,食物中毒的可能性是相当小的)和第六段可知,食物中毒是可以控制的。另外,选项C和选项D的意思恰恰相反, 遇上这种情况,一般说来, 必有一个是正确答案, 解题时重点核对这两个选项即可。 复 记 强 化 deadly

recover from从……中恢复
have a bad reaction to… 对……有不良反应 [难句理解] If people eat natural poisons, they must go to the hospital right away to have their stomachs emptied. 结构分析:句中if引导一个条件状语从句, 主句中不动式短语to have their stomachs emptied作目的状语; 因stomachs与empty是被动关系, 故用过去分词作宾补, 即have sth. done (让人做某事)句型。
