If you bought some candy months ago but never ate it, how can you tell whether it is still safe to eat? The easiest way is to check the“use-by date” 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 new report from the US Natural Resources Defense Council(NRDC), 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.
But the truth is that these dates aren’t related to the risk of food poisoning or food-born illness, according to Time News
use-by dates and related them to the safety of the food, and they still largely do now. 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-flavored drinks may lose their red color and biscuits may lose their crunch(嘎吱嘎吱的声音), but they are not harmful.
“It’s a confusing subject, the difference between food quality and food safety,” said Jena Roberts, vice president of National Food Lab, a US food testing company. “Even in the food industry I have colleagues who get confused.”
This is why scientists are calling for a standard explanation to be printed following the use-by dates. “We want this to be clearly communicated so consumers are not misunderstanding the date and contributing to a lot of waste,” said Dana Ganders, a staff scientist with the NRDC.
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 safe to eat 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 go bad.
4. The use-by date was first intended to ________.
A. tell the freshness of food
B. show the safety of food
C. give a warning of food poisoning
D. indicate the relation between food and illness
5. The underlined word “misinterpreted” in Paragraph 4 probably means “________”.
A. made guesses about
B. formed a wrong idea about
C. made wrong use of
D. took no notice of
6. Which of the following is TRUE?
A. Most customers understand what use-by dates mean.
B. “Use-by dates” have existed for more than 50 years.
C. Biscuits can’t be eaten when not as crunchy as they were bought.
D. Even after their use-by dates pass, some foods are still safe to eat.
7. Scientists are calling for a standard explanation to be printed together with the use-by dates because________.
A. use-by dates are not helpful or reliable
B. more consumers get worried about food safety
C. most consumers often misunderstand use-by dates
D. the quality level of different foods changes differently

篇二：生命的内涵
生命的内涵
汪倩倩
淡淡云，漫漫月，时间流转，唯有那一份淡淡的沁人梅香一直未变，就在我心中，那个可以遗忘生命的地方。——题记
远处繁杂的喧嚣让我思索。芸芸众生，有的像雄鹰——展翅蓝天，有的像海鸥——让暴风雨来得更猛烈些吧！有的像夏蝉——总是“知了知了”喊个不停??敢问众生，生命的内涵，人间正道在何方？
生命的内涵到底是什么？
我抬头问那蔚蓝无际的苍穹，他没有回答。
远处繁杂的喧嚣逐渐在我的耳畔被空虚消弭，于是仿佛置身于另外一个人间，那里有浅浅的微风拂过大地的面颊；大地的面颊映出盈盈的积雪；盈盈的积雪漫着暖暖的阳光；暖暖的阳光衬着浅浅的微风，我听见了冬的低语。
远处，有一株凌寒独自开的梅。
梅正高昂着头，看着这个银装素裹的世界。
多少峥嵘岁月，梅都不曾退缩过；多少寒苦日子，梅都不曾放弃过；多少冰冷日月，梅都不曾抱怨过。然而又换来什么了呢？是文人墨客为梅而驻足，为她而吟作画？还是英雄豪杰为梅倾倒，为她歌颂赞美？不，不是。她那卓尔不群的心，从未被这些事所动摇。
但是梅也从没看过春日的美丽呀！她也未曾看见百花齐放的壮丽呀！难道那漆黑的夜和刺骨的风，没有袭她以莫名的孤寂和落寞吗？
生命的内涵到底是什么？
我轻声问傲雪的梅，她没有回答。
不，我听见了她的回答，轻轻的，细细的，但是坚定的，不屈的。 她只是用自己生命的力量去装点冬日的美丽，尽管寒冷却没有一丝怨言，她不愿去给春天的百花争夺美丽，她只是用心地去做他自己。
梅总逃脱不了被春日遗忘的命运，等到冬日的银白徐徐褪去，她也会飘零而去，使人不忍回眸，只好静静等待，听见耳畔悲切的哀鸣，回头望去，却看见一张含着眼泪的笑脸，静静的等待着，等待着她零落成泥碾作尘的大结局。
当梅散落在地，渐渐融入大地，成为这春的一份子的目标便是她生命的终点，她——找到了生命的快乐，她用自己的身躯去滋润养育过她的土地，等待着百花的诞生，用自己的遗骸去帮助春天拥有更美丽的颜色。
梅的一生，她内涵如风，轻舞飞扬；内涵如雨，洞穿万物；内涵如泉，抚平浮躁。她在艰苦的世界绽放，却不与百花争艳，只是百花待放之时，她献
