●Poultry: 4. ; pieces of birds keep their quality for up to nine months.

●Fish: For best quality, fatty fish (salmon, tuna) should be consumed within two to three months. Lean fish (cod, flounder) should be consumed within six months.

A. Raw meat

B. General leftovers

C. Whole birds can keep their quality for up to a year

D. The point of that process is to stop the enzyme（酶）process

While you are heating your food, you may wonder how close you can safely stand next to a microwave, and whether any radiation could escape from the device and potentially harm you.　

In theory, microwaves can heat body tissues in the same way they heat food, and at high levels, microwaves can cause burns and cataracts. 1. They will generally occur when people are exposed to large amounts of radiation escaping through openings in the oven. As a result, there is little cause for concern about using microwaves ovens, unless there is damage to the door.

Still, the FDA (美国食品和药物管理局) recommends that you check your microwave oven carefully and do not use it if the door doesn't close properly, or if it is "bent, warped, or otherwise damaged."　 2.

As far as injuries from microwave ovens go, the most common way people are injured is via heat-related burns from touching hot containers or overheated foods, or being exposed to exploding liquids. 3.

The agency also warns that, when you use a microwave to heat water in a cup, there's a risk of the water becoming "superheated," which means it has heated past its boiling point. 4.But just a slight disturbance to the water — which can occur when touching or picking up the cup — can cause an eruption of boiling water. This can lead to skin burns or scalding injuries, particularly on the face and hands. To prevent superheated water from forming, the FDA says people should not exceed the recommended heating time for water, as indicated in the oven's instruction book.

5.

A.But these types of injuries are very rare.

B.When this happens, the water does not appear to be boiling.

C.However, injuries from microwave radiation are unavoidable sometimes.

D.Though microwaves don't affect health as X-rays do, that doesn't mean they are risk-free.

E.People should use common-sense precautions when handling hot foods in microwaves.

F.Indeed, it's a good idea to follow the instruction book to help keep yourself safe when using it.

G.Besides, it is suggested that you don't lean against a microwave for too long during operation.

If you bought some candy months ago but never ate it, how can you tell whether it’s still safe to eat? 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 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 1970s because customers 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. However, most customers misinterpreted 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 juice may lose its red color and biscuits may lose their crunch（松脆的口感）, 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 customers are not misinterpreting the date and contributing to a lot of waste,” said Dana Gunders, 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 eatable 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 throw away.

1.According to the text, use-by date was first intended to ________.

A. reduce the waste of food

B. show whether the food was fresh

C. show the safety of food

D. give a warming of food poisoning

2.Which of following is TRUE?

A. Most customers understand what use-by date mean.

B. Biscuits can’t be eaten when not as crunchy as they were bought.

C. “ Use-by dates” have existed for more than 50 years.

D. Even after their use-by dates pass, some food are still safe to eat.

3.Scientists are calling for a standard explanation to be printed together with the use-by dates because________.

A. Most consumers often misunderstand use-by dates

B. use-by dates are not helpful or reliable

C. more consumers get worried about food safety

D. the quality level of different foods changes differently

How long does a year last? 1. But your parents might say that a whole year can pass “in the blink of an eye”. Why does time seem to pass faster as we get older?

2. This physical change causes the rate at which we take in and process new information to decline. Babies, for example, move their eyes much more often than adults because they’re processing images at a faster rate. They take in a lot of information and do many things in a single day. 3. However, as people’s brains degrade over time, fewer images are processed in the same amount of time. Therefore, older people receive less information during a day than younger people. This causes things to seem as though they’re happening more quickly.

4. People may measure time by the number of memorable events that can be recalled within a certain period. Have you ever noticed that when you recall your firsts (first day of school, first family vacation, first birthday party, etc.), they seem to be in slow motion? That’s because when something is a “first”, there are many exciting things to remember. Recalling these memories makes you feel like they took forever.

For many adults, life is routine. When they look back, they might feel like there are not many novel (新奇的) things to remember. 5.

A.Children might say that a year lasts forever.

B.Therefore, time seems to be moving faster to them.

C.Different people have different feelings toward time.

D.This makes them feel like a single day lasts for a long time.

E.As we grow older, we become less interested in new things.

F.According to scientists, our brains degrade　 and change over time.

G.In addition, people may also “feel” time differently due to psychological reasons.
