Cleaning your plate may not help feed hungry children today, but the timeworn advice of mothers everywhere may help reduce food waste from the farm to the fork, help the environment and make it easier to feed the world’s growing population.

Hard data still being collected, but experts in Chicago said about 30% to 50% of the food produced in the world goes uneaten. The average American throws away 33 pounds of food each month—about $40 worth, which means each person throws away almost 400 pounds of food. The US Department of Agriculture says that 23% of eggs and an even higher percentage of produce ends up in the trash.

“We forget we have all these fresh fruits and vegetables, and at the end of the week we have to throw them away”, said Esther Gove, a mother of three young children in South Berwick, Maine. “Now, I don’t buy as much fresh produce as I used to.”

But the effect of food waste arrives far beyond the kitchen. Agriculture is the world’s largest user of water, a big consumer of energy and major emitter of greenhouse gases during production. Experts say reducing waste is a simple way to cut stress on the environment and can ease pressure on farmers, who will be called on to feed an expected 9 billion people around the world in 2050, compared with nearly 7 billion today.

No matter how sustainable (可持續(xù)的) farming is, if the food’s not getting eaten, it’s not sustainable and it’s not a good use of our resources. In richer nations, fruit and vegetables end up in the trash because they aren’t pretty enough to meet companies’ standards, have gone bad in a home refrigerator or aren’t eaten at a restaurant. In developing countries, much food spoils before it gets to market due to poor roads and lack of refrigeration. High food prices are another reason, since some people can’t afford the food that’s produced.

1.From the first paragraph, we know that cleaning your plate ________.

A. is you mother’s best advice for you

B. can solve certain problems for the world

C. can help feed hungry children all over the world

D. helps meet the growing population’s needs

2.The underlined word “emitter” in Paragraph 4 means ________.

A. user B. finder C. protector D. producer

3.What is a sustainable and convenient way for a customer in a restaurant?

A. Ordering enough and packing the leftovers.

B. Ordering more than he or she can eat.

C. Ordering less and feeling hungry after leaving.

D. Ordering more and leaving the untouched alone.

4.Which of the following topics will follow the text?

A. More examples of food waste. B. Ways to reduce food waste.

C. Experts’ idea on the environment. D. Advice for food with high prices.

Taking a photo of your food and posting it online is becoming more and more popular. However, not everyone thinks it’s such a good idea.

Food photos are popular on social networking sites. People often post pictures of their meals on Facebook or photo sites such as Tumblr and Instagram. Many of the pictures are of delicious-looking food from top-class restaurants. Some people even find it addictive（上癮的）. “I couldn’t get enough of it. I had to IG (instagram) every single meal,” one food poster wrote.

However, not all food photos are so attractive. There are now sites where you can post pictures of terrible-looking food. One such website is saddesklunch.com. Users send pictures of their depressing meals, which include things such as half-eaten bits of chicken and leftover pizza.

Sad Desk Lunch was created by office worker Kira Fisher in 2012. At the time, she was working as a video editor in New York. “I was starting at my rather terrible vegetable soup, which I was eating at my desk, and just thought, I can’t believe I’m eating this soup, let alone eating it alone at my desk,” she said. Other similar sites include cooksuck.com, foodporndairy.com and dimlyiitmealsforone. Tumblr.com.

Some chefs are trying to stop people photographing food in their restaurants. Gilles Goujon runs a three-star restaurant in southern France. He told news website France TV Info that every time his creations appear on social networks it “takes away the surprise, and a little bit of my intellectual property（知識(shí)產(chǎn)權(quán)）”.

Alexandre Gauthier is the chef at the “Grenouillere” restaurant a “no camera” logo on his menus. “Before, people took pictures of their family in the restaurant; now we take pictures of food... We tweet, we ‘like’（點(diǎn)贊）, we respond to comments, and the dish is cold,” he explained.

Will you be taking your camera next time you eat out?

1.On which of the following websites can you probably find photos of tasty food?

A. cooksuck.com B. instagram.com

C. saddesklunch.com D. foodporndairy.com

2.What’s Gilles Goujon’s attitude towards food photography in restaurants?

A. He dislikes it. B. He supports it.

C. He is interested in it. D. He is uncertain about it.

Dear Paul,

I really can’t thank you very much for your invitation.

I do want to accept them and take this opportunity to introduce traditional Chinese paintings to foreign friends, but I’m sorry to inform you that I can’t. The reason is because I am busy preparing myself for the coming College Entrance Examination. As for the introduction speech, I strongly recommend my friend Anna, that is the most suitable choice to take my place on next Sunday. She begun to learn paintings at an early age and has good knowledge of traditional Chinese paintings. However, her active personality and perfect spoken English will help making your activity a success.

Sorry again for any inconvenience caused by my absence and all the best wish to you.

Sincerely yours,

科目：高中英語 來源：廣西玉林市畢業(yè)班質(zhì)量檢測(cè)英語試卷 題型：閱讀理解

While dog keepers realize their dogs can read their moods accurately, scientists have always been a little doubtful. Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some convincing evidence.

For their study, biologist Corson Miller and his team exposed eleven selected dogs to digital images of women that were either angry or happy. Half the dogs were rewarded for touching the screen when shown a happy face, while the other half got their treat for selecting those that appeared angry.

Interestingly, the dogs were not provided with the entire face. Some dogs were shown only upper halves while the others observed lower halves. That’s because the scientists believe humans show their emotions on their entire face.

After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face. The researchers concluded the dogs were smart enough to read human emotions.

They also found those being trained to read angry expressions took a longer time to learn. They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly. However, once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear. In fact, the dogs had such a good time playing the computer "game" that scientists had a hard time keeping them away from the touch screens after the study was completed.

The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly. Since the touchscreen models were all females, this confirmed what has been observed in previous studies—dogs are more efficient at reading facial expressions of people that are the same gender as their owner.

1.How did the scientists conduct the experiment?

A. By mixing the selected dogs together.

B. By leaving dogs to women who are either happy or angry.

C. By showing digital pictures of women’s happy or angry faces.

D. By rewarding only half of the dogs touching the screen.

2.Which of the following statements is TRUE about the dogs in the study?

A. The dogs were not all provided with the entire face.

B. The dogs couldn’t read strangers facial emotions.

C. According to their size, the dogs were given either upper or lower halves.

D. The dogs could make out small changes accompanying facial expressions.

3.The underlined word "trepidation" in Paragraph 5 probably means ________.

A. curiosity B. horror C. excitement D. doubt

4.How might the results change if the dogs with female owners are shown pictures of male faces?

A. They would be scared away at the sight of the pictures.

B. They found it easy to tell the emotions on the entire face.

C. They could only tell emotions on partial faces rather than on entire faces.

D. They found it hard to tell the moods on the faces of a different gender.
