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 (保質(zhì)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.a(chǎn)ccording 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 本文是一篇科普類閱讀,講述了關(guān)于食品的保質(zhì)期的問題,很多人都以為食物到了保質(zhì)期就不能食用,其實這樣會造成很多浪費.很多食物的保質(zhì)期到了只會影響口感等,是可以食用的.
解答 51.答案:B.細(xì)節(jié)理解題.根據(jù)"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,每年上噸的食物被丟棄,因為超過了保質(zhì)期.故選B.
52.答案:B.細(xì)節(jié)理解題.根據(jù)"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,最初設(shè)置保質(zhì)期是為了表示在此時間食物是新鮮的.故選B.
53.答案:D.推理判斷題.根據(jù)"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."可推測出,作者舉例是為了說明有些食物過了保質(zhì)期后還可以吃.故選D.
54.答案:C.細(xì)節(jié)理解題.根據(jù)"We want this to be clearly communicated so customers are not misinterpreting the date and contributing to a lot of waste,"可知,保質(zhì)期容易誤導(dǎo)消費者,隨之產(chǎn)生不必要的麻煩.故misunderstanding意為理解錯誤.故選C.
55.答案:A.推理判斷題.A.設(shè)定食物質(zhì)量的標(biāo)準(zhǔn)很難;B.食物保質(zhì)期應(yīng)該被停用;C.食品工業(yè)應(yīng)對食物味道負(fù)責(zé);D.人們很容易接受新的標(biāo)準(zhǔn).根據(jù)最后一段內(nèi)容及全文內(nèi)容可知,因此,食品行業(yè)官員正在考慮更改有效期日期指示當(dāng)食物是壞的.故A符合文章內(nèi)容,BCD均不符合.故選A.
點評 本文是一篇科普類文章,題目涉及多道細(xì)節(jié)理解題及推理判斷題,做題時應(yīng)結(jié)合文章上下文內(nèi)容,仔細(xì)閱讀原文并根據(jù)所給選項的含義進(jìn)行分析,從而得出正確答案.切記胡亂猜測,一定要做到有理有據(jù).
