The arugula (芝麻菜)was
9、 to make a nice green salad, rounding out a roast chicken dinner. But I ended up working late. Then friends called with a dinner invitation. I stuck the chicken in the freezer. But as days passed, the arugula went bad. Even worse, I had unthinkingly bought way too much; I could have made six salads
10、with what I threw out.In a world where nearly 800 million people a year go hungry, “food waste goes against the moral grain,” as Elizabeth Royte writes in this months cover story. Its jaw-dropping how much perfectly good food is thrown away from “ugly” (but quite eatable) vegetables rejected by groc
11、ers to large amounts of uneaten dishes thrown into restaurant garbage cans.Producing food that no one eats wastes the water, fuel, and other resources used to grow it. That makes food waste an environmental problem. In fact, Royte writes, “if food waste were a country, it would be the third largest
12、producer of greenhouse gases in the world.”If thats hard to understand, lets keep it as simple as the arugula at the back of my refrigerator. Mike Curtin sees my arugula story all the time but for him, its more like 12 bones of donated strawberries nearing their last days. Curtin is CEO of DC Centra

16、ook after to stop them feeling lonely. The project was dreamed up by a local charity (慈善组织) to reduce loneliness and improve elderly peoples wellbeing. It is also being used to help patients suffering dementia, a serious illness of the mind. Staff in care homes have reported a reduction in the use o
17、f medicine where hens are in use.Among those taking part in the project is 80-year-old Ruth Xavier. She said: “I used to keep hens when I was younger and had to prepare their breakfast each morning before I went to school. ” “I like the project a lot. I am down there in my wheelchair in the morning
18、letting the hens out and down there again at night to see theyve gone to bed.”“Its good to have a different focus. People have been bringing their children in to see the hens and residents come and sit outside to watch them. Im enjoying the creative activities, and it feels great to have done someth

Wendy Wilson, extra care manager at 60 Penfold Street, one of the first to embark on the project, said: “Residents really w

23、which are formed by touching the lower lip to the upper teeth.（此处为定语从句） 原文Human speech contains more than 2,000 different sounds, from the common “m” and “a” to the rare clicks of some southern African languages. But why are certain sounds more common than others? A ground-breaking, five-year study
24、shows that diet-related changes in human bite led to new speech sounds that are now found in half the worlds languages. More than 30 years ago, the scholar Charles Hockett noted that speech sounds called labiodentals, such as “f” and “v”, were more common in the languages of societies that ate softe
25、r foods. Now a team of researchers led by Damin Blasi at the University of Zurich, Switzerland, has found how and why this trend arose. They discovered that the upper and lower front teeth of ancient human adults were aligned (对齐), making it hard to produce labiodentals, which are formed by touching
26、 the lower lip to the upper teeth. Later, our jaws changed to an overbite structure (结构), making it easier to produce such sounds.The team showed that this change in bite was connected with the development of agriculture in the Neolithic period. Food became easier to chew at this point. The jawbone
27、didnt have to do as much work and so didnt grow to be so large.Analyses of a language database also confirmed that there was a global change in the sound of world languages after the Neolithic age, with the use of “f” and “v” increasing remarkably during the last few thousand years. These sounds are
28、 still not found in the languages of many hunter-gatherer people today.This research overturns the popular view that all human speech sounds were present when human beings evolved around 300,000 years ago. “The set of speech sounds we use has not necessarily remained stable since the appearance of h
29、uman beings, but rather the huge variety of speech sounds that we find today is the product of a complex interplay of things like biological change and cultural evolution,” said Steven Moran, a member of the research team.2022 年新高考卷IIB1.We journalists live in a new age of storytelling, with many new

Then I turned the page and continued. He poked the page even harder. I nearly dropped the book. I was confu

His father frequently amused the boy with a tablet computer which was loaded with colorful pictures that come alive when you poke them. He thought my storybook was like that. Sorry,
34、kid. This book is not part of your high-tech world. Its an outdated, lifeless thing. An antique, like your grandfather. Well, I may be old, but Im not hopelessly challenged, digitally speaking. I edit video and produce audio. I use mobile payment. Ive even built websites. Theres one notable gap in m

Americans are still texting while driving, as well as using social networks and taking photos. Road accidents, which had fal

That is partly because people are driving more, but Mark Rosekind, the chief of the National Highway Traffic Safety Administration, said distracted（分心）driving was only increasing, unfortunately.Big change requires big ideas. he said in a speech last month, refe
40、rring broadly to the need to improve road safety. So to try to change a distinctly modern behavior, lawmakers and public health experts are reaching back to an old approach: They want to treat distracted driving like drunk driving. An idea from lawmakers in New York is to give police officers a new
41、device called the Textalyzer. It would work like this: An officer arriving at the scene of a crash could ask for the phones of the drivers and use the Textalyzer to check in the operating system for recent activity. The technology could determine whether a driver had just texted, emailed or done any
42、thing else that is not allowed under New Yorks hands-free driving laws. We need something on the books that can change peoples behavior,” said Flix W.

In the beginning, it is flexible, but put it in a drawer for 20 years and it will become dry and easily broken,” says Dr. Ben Levine, a
46、 heart specialist at the University of Texas. Thats what happens to the heart. Fortunately for those in midlife, Levine is finding that even if you havent been an enthusiastic exerciser, getting in shape now may help improve your aging heart. Levine and his research team selected volunteers aged bet

After two years, the second group saw remarkable improvements in heart health. “We took these 50-year-old hearts and turned the clock back to 30-or 35-year-old hearts,” says Levine. “And the reason they got so much stronger and fitter was
49、that their hearts could now fill a lot better and pump (泵送) a lot more blood during exercise.” But the hearts of those who participated in less intense exercise didnt change, he says. “The sweet spot in life to start exercising, if you havent already, is in late middle age when the heart still has f
