If you bought some candies months ago but never ate it, how can you tell whether it's still eatable? The easiest way is to check the"expiration（截止） date （EXP）"printed on the cover. If that date has already passed, you're likely to throw the candies away. But is that really necessary?

According to a new report from the NRDC, tons of food is wasted each year, largely because people don't fully understand what expiration dates, or" use﹣by dates", actually mean, so they think the food is not safe to eat. 

Food dating was introduced in 1975 because customers wanted more information about the things that they were eating. When they first showed up, use﹣by dates only showed freshness because producers wanted their products to be tasted in their best conditions. 

However, most customers mistakenly believed that use﹣by dates showed how safe the food was. But the truth is that these dates aren't related to the danger of food poisoning（中毒）. Eggs, for example, can still be eaten three to five weeks after being bought, even though the use﹣by date is much earlier. When their use﹣by dates pass, cookies may lose their crunch （松脆 的口感）, but they are not harmful. 

"It's an unclear subject, the difference between food quality（质量） and food safety, "said Jena Roberts from a US food testing company. "Even the workmates in the food factory are not sure about it. This is why the use﹣by dates must be printed on the covers of products. "We hope it can help customers understand the information so that they won't waste a lot of food. "

Another problem is that the quality levels of different foods change differently. Some are still eatable long after their use﹣by date while others are not. 

As a result, food factory officials are now thinking of changing the use﹣by date to a date which can show when food is most likely to be thrown away.

14. Which of the following pictures can show the meaning of"expiration date （EXP）"?

A.  B.  

C.  D.  

15. What did the use﹣by dates show at first according to the passage?

A. Food freshness. B. Food quality.

C. Food safety. D. Food producer.

16. What can we learn from Paragraph 4?

A. Most customers care more about freshness than food safety.

B. Most customers fully understand what expiration dates mean.

C. "Expiration dates"were first used to show when food was likely to go bad.

D. Even after their expiration dates pass, some foods are still safe to eat.

17. What is probably the best title for this passage?

A. Customers and Food B. Food Quality and Freshness

C. Food Dating D. Expiration Dates and Food Safety
