13.If you bought some candy months ago but never ate it.how can you tell whether it's still edible (可以吃的)?The easiest way is to check the"expiration date (保质期)"printed on the wrapper.If that date has already passed,you're likely to throw the candy away.But is that really necessary?According to a report,tons of food is wasted each year,largely because people don't fully understand what expiration dates,or"use-by dates",actually mean.
Food dating was introduced in the 1970s,because consumers wanted more information about the things that they were eating.When they first showed up,use-by dates were only supposed to indicate freshness because producers wanted their products to be tasted in their best conditions.However,most customers mistakenly believed that use-by dates indicated how safe the food was,and they still largely do.But the truth is that these dates aren't related to the risk of food poisoning or food-borne illness.according to Time News.
Eggs,for example,can still be eaten three to five weeks after purchase,even though the use by date is much earlier.When their use-by dates pass,strawberry juice may lose its red color and biscuits may lose their crunch (松脆的口感) but they are not harmful.
To stop consumers from misinterpreting the date and reduce the waste,scientists are calling for a standard explanation to be printed following the use-by dates.
But this won't be a mistake that is easy to correct,since people have believed it for so long.Another problem is that the quality levels of different foods change differently-some are still edible long after their use-by date while others are not.
As a result,food industry officials are now thinking of changing the use-by date to a date indicating when food is most likely to spoil.

分析 本文是一篇科普类阅读,讲述了关于食品的保质期的问题,很多人都以为食物到了保质期就不能食用,其实这样会造成很多浪费.很多食物的保质期到了只会影响口感等,是可以食用的.
解答 51.答案:B.细节理解题.根据"According to a report,tons of food is wasted each year,largely because people don't fully understand what expiration dates,or"use-by dates",actually mean"可知,每年上吨的食物被丢弃,因为超过了保质期.故选B.
52.答案:B.细节理解题.根据"When they first showed up,use-by dates were only supposed to indicate freshness because producers wanted their products to be tasted in their best conditions"可知,最初设置保质期是为了表示在此时间食物是新鲜的.故选B.
53.答案:D.推理判断题.根据"Another problem is that the quality levels of different foods change differently-some are still edible long after their use-by date while others are not."可推测出,作者举例是为了说明有些食物过了保质期后还可以吃.故选D.
54.答案:C.细节理解题.根据"We want this to be clearly communicated so customers are not misinterpreting the date and contributing to a lot of waste,"可知,保质期容易误导消费者,随之产生不必要的麻烦.故misunderstanding意为理解错误.故选C.
55.答案:A.推理判断题.A.设定食物质量的标准很难;B.食物保质期应该被停用;C.食品工业应对食物味道负责;D.人们很容易接受新的标准.根据最后一段内容及全文内容可知,因此,食品行业官员正在考虑更改有效期日期指示当食物是坏的.故A符合文章内容,BCD均不符合.故选A.
