Changing the wording about expiration dates (保质期) on food items of easily going bad — which is currently unregulated (缺乏监管) and widely variable — could help reduce food waste, according to a new Cornell University study.
This work results from the “wild west” landscape of food date labels which is expected to be driven, to a large extent, by manufacturers’ (制造商) strong wish to sell more products. It is important for both the government’s decisions regarding date labels and the market impacts of reducing food waste.
A survey of consumers found that certain wording — “best by,” as opposed to “best if used by,” for example — had the possibility to reduce food waste, but that result differed depending on the type of food in question. The easier food is to go bad, the more likely it is to be thrown away.
“There are no practical rules about food date labels in the U.S. If you go into the yogurt section at a U.S. grocery store, you would see various date labels — ‘use by’, ‘best by’, ‘best if used by’, ‘fresh by’, or ‘sell by’, etc. Some consumers might smell the food to see if it is still good, while others might just look at the date label and drop it,” said Rickard, leader of the study team. “And the truth is that these date labels are not food safety dates; they’re just food quality dates.”
The 15 food items selected for the survey, including bread, cookies, chicken, packaged salad greens and canned soup, all typically use date labels with different wording variations. Survey results showed an increase in throwing intentions with the “use by” and the “sell by” date label, inferring that food with these date labels was more often thrown and replaced. So they think that the word “use” spoke more directly to the food safety impact of consuming food past the date listed on the package, and could therefore lead to an increase in food waste. However, the wording “best by” seemed to refer only to food quality beyond a certain date and led to less waste.

【推荐3】We all regard receiving presents as a pleasant experience and yet it can be one of the most awkward situations. It is often difficult to look pleased when you receive a gift which is useless or the wrong size.
So you will have to tell your favourite aunt that the T-shirt does not fit. But an exchange is not always that simple because there has to be a good reason for it.
But if you are returning something, no matter what the reason is, you will be expected to have proof of purchase. If the receipt cannot be found, then it is possible to use another proof of purchase such as a credit card receipt. If all of these have been lost, you may have to rely on a witness.
Many big stores have a much more tolerant policy towards return and see it as a gesture of good will to exchange goods without question. Stores including Marks & Spencer are well-known for their “no argument” policy on returned goods.
So if a shop refuses to exchange the goods or to offer a refund, the seller is likely to be within his legal rights unless there is something wrong with the goods. In that case, the boot is on the other foot. You have every right to demand a cash refund or a replacement, but only if you have returned it within a “reasonable” time.
A.It is unlike anything you would buy for yourself. |
B.However, shoppers should remember this is a privilege, not a right. |
C.Unfortunately, the law does not explain what it meant by “reasonable”. |
D.All you can do is exchange it after your friend or relative has gone home. |
E.Either the thing has to be broken or unsuitable for the job it was intended to do. |
F.You should make clear what your legal position is before returning goods to the shop. |
【推荐1】Here are four tips to help you prepare a better cup of coffee from the comfort of your kitchen:
Start with good materials.
At its simplest, a cup of coffee consists of two things: coffee and water.
When it comes to the other main material, it goes beyond just buying “good” coffee. Try choosing fresh coffee. Like sonic fruits coffee will go bad with time, and the unique flavors will start to fade away.
Get a good coffee grinder.
Good grinders run col fee beans through two gear-like circles. They allow for a more uniform grind size compared to common grinders, although they tend to be bigger and more expensive. There are mechanized grinders and hand control ones.
Develop Your Recipe.
The proportion of coffee to water is a personal thing. Walimaki likes a 1:16 proportion.
Don’t expect to become some kind of expert taster overnight. Walimaki notes “The more you taste something, the better you’re going to get at identifying what’s good and what’s bad. If you’re having trouble naming what you taste try using a flavor wheel — a handy tool that can help you pick out exactly what you’re tasting.
A.Learn to describe what you taste. |
B.That is one part coffee to 16 parts water. |
C.There can be more to coffee than just what’s in your cup. |
D.The taste of your water will affect the taste of your coffee. |
E.It starts with more general tastes in the center like fruit and nut. |
F.Drink your morning coffee at home while catching up on the news. |
G.By breaking up beans yourself at home, you can choose your preferred powder. |
【推荐2】There’s nothing wrong with a tomato that isn’t perfectly rounded or a peach with an extra dimple (浅凹) or two; they still carry the same benefits and flavors as the versions we’re used to seeing in grocery stores. Farmers conventionally throw away these imperfect items, as many grocery chains won’t buy them for fear that they are unsellable. However, a growing group of grocery chains are fighting to make these deserted fruits and vegetables part of consumers’ buying habits.
One such business is Imperfect Produce, a start-up that delivers fresh ugly produce to consumers. Through this service, you can get up to 20 pounds of fruit and veggies for around $20 a week. This is about a 30 percent discount compared to what’s currently sold in stores. Recently, the company had a major breakthrough when Whole Foods accepted their partnership and agreed to sell the misshapen (畸形的) produce.
While this movement might be a new trend here in the US, it’s already gained serious momentum (势头) in Europe. In 2014, the E. U. announced the Year Against Food Waste, with French grocery chain Intermarche launching a very successful campaign called Inglorious Fruits and Vegetables and England’s Waitrose selling weather blemished apples. In Portugal, a similar company to Imperfect Produce called Fruta Feia has also taken off.
Buying these unfortunate-looking foods should be appealing to consumers not only because of the affordability,but also because of the support it gives to farmers and the direct impact it has on decreasing food waste and the environmental pollution. It is believed that when the discarded fruits and vegetables decompose they release methane, a greenhouse gas that, when released into the atmosphere, is about 86 times as powerful as carbon dioxide over a 20-year period. Waste is, in fact, the ugliest thing of all.
1. What do farmers do with imperfect fruits and vegetables traditionally?A.Throw them away. | B.Tun them into fertilizer. |

A.To make better profits. | B.To sell imperfect produce. |
C.To get discounts from farmers. | D.To compete with Whole Foods. |

C.It addresses the problem of misshapen produce earlier. |
D.It faces a more serious problem of unfavorable weather. |

【推荐3】It is food news guaranteed to put a smile on your face. Scientists have found that eating dark chocolate appears to lower the risk of depression by a quarter. While 7.6 percent of the 13,000 people surveyed reported depressive symptoms, just 1.5 percent of the chocolate eaters did.
The study by University College London (UCL), the University of Calgary and Alberta Health Services Canada, also found that the people who consumed the most of any chocolate were also 57 percent less likely to report depressive symptoms. Lead author Dr. Sarah Jackson said, “This study provides some evidence that consumption of chocolate, particularly dark chocolate, may be associated with reduced odds of clinically relevant depressive symptoms.”
The study is the first to examine the association with depression according to the type of chocolate consumed. The team assessed data from 13,626 adults from the US National Health and Nutrition Examination Survey. A range of other factors including height, weight, marital status, ethnicity, education, household income, physical activity, smoking and chronic health problems were also taken into account to ensure the study only measured chocolate’s effect on depressive symptoms.
After adjusting for these factors, it was found that individuals who reported eating any dark chocolate in two 24-hour periods had 70 percent lower odds of reporting clinically relevant depressive symptoms in the previous two weeks than those who reported not eating chocolate at all.
Chocolate contains a number of psychoactive ingredients which produce a feeling of euphoria similar to that of cannabinoid (大麻素), found in cannabis. It also contains phenyl ethylamine (苯乙胺), a neuromodulator (神经调节物质) which is believed to be important for regulating people’s moods. Dark chocolate also has higher concentration of flavonoids (类黄酮), antioxidant chemicals which lower inflammation and can prevent the onset (发生) of depression.
However, British scientists pointed out that the decision to eat dark chocolate could be linked to other health factors. For example, people who choose dark chocolate may be more health conscious in general, which is known to protect against depression. Depressed people are also more likely to desire for more sugary fatty foods and so could be less likely to pick a dark alterative when choosing chocolate.
1. Which of the following statements is TRUE of the study?A.minority of chocolate eaters suffer from depression. | B.majority of people surveyed are depressive. |
C.All kinds of chocolate can help fight depression. | D.Half of people with depression are surveyed. |

Some of the threats are natural, such as wildfires, hurricanes, tornados, floods and so on. But the biggest threats to the food chain come from you and me. These threats include overhunting, overfishing, logging, farming, development, pollution, etc. The food chain is endangered anywhere humans have had an effect on the natural environment.
A recent study shows that the overfishing of large sharks is damaging the food chain along the US Atlantic coast. Canadian and American scientists say sharks are being killed in great numbers for their meat and fins(鳍). Now, not enough sharks are around to eat the cownose(牛鼻) ray. The ray’s population has increased and they have eaten up the shellfish to the point where it has hurt commercial(商业的) fishing.
Many of us disturb the natural environment in our own backyards. It’s up to us to take care of the environment and try not to disrupt the natural food chain. If we don’t act responsibly, animals will start disappearing.

D.suggest that we not disrupt the natural food chain |
The information gained helped us in determining where special attention should be paid in our course. Although many students have chosen to join the course with a reasonable motivation(动机), we considered it important to note what seemed to encourage interest. Nearly all the students have experienced some kind of grammar-based English teaching in their own country. To use the same method would be self-defeating because it might reduce motivation, especially if it has failed in the past. Therefore a different method may help because it is different.
Variety of activity was also seen as a way of maintaining(保持)or increasing motivation. Several years ago we had one timetable that operated throughout, but we soon found that both the students and the teachers lost interest by about halfway through the ten weeks. This led us to a major re-think, so finally we brought it into line with the expressed language needs of the students.

【推荐3】It is easier to float in the ocean than it is to float in a swimming pool. Do you know why?
Ocean water is full of salt—and salt water can hold up more weight than fresh water. See for yourself!
You Will Need:
3 cups of warm water
·Measuring cup(量杯)
·Wide-mouthed jar
·Salt
·Spoon
·Raw(生的)potato
You Will Do:
1. Pour 1. 5 cups of warm water into the jar.
2. Add 1/3 cup of salt.
3. Stir(搅拌)until the salt is completely
dissolved.
