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 shows that diet-related changes in human bite led to new speech sounds that are now found in half the world’s 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 softer foods. Now a team of researchers led by Damián 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 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 didn’t have to do as much work and so didn’t 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 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 human 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.

The benefits of regular exercise are well documented but there’s a new bonus to add to the ever-growing list. New research found that middle-aged women who were physically fit could be nearly 90 percent less likely to develop dementia (失智症) in later life — and if they did, it came on a decade later than less sporty women.
Lead researcher Dr Helena H rder, of the University of Gothenburg in Sweden, said: “These findings are exciting because it’s possible that improving people’s cardiovascular (心血管的) fitness in middle age could delay or even prevent them from developing dementia.”
For the study, 191 women with an average age of 50 took a bicycle exercise test until they were tired out to measure their peak (最大值的) cardiovascular capacity. The average peak workload was measured at 103 watts.
A total of 40 women met the criteria for a high fitness level with a capacity of 120 watts or higher, while 92 women were in the medium fitness category. A total of 59 were of low fitness level, with a peak workload of 80 watts or less, or having their tests stopped because of health problems.
These women were then tested for dementia six times over the following four decades. During that time, 44 of the women developed dementia. Five percent of the highly fit women developed dementia, compared to 25 percent of the women with medium fitness and 32 percent of the women with low fitness.
“However, this study does not show cause and effect between cardiovascular fitness and dementia, it only shows an association,” said H rder. “More research is needed to see if improved fitness could have a positive effect on the risk of dementia and also to look at when during a lifetime a high fitness level is most important.” She also admitted that a relatively small number of women were studied, all of whom were from Sweden, so the results might not be applicable to other groups.

Like most of us, I try to be mindful of food that goes to waste. The arugula (芝麻菜)was 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 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 month’s cover story. It’s jaw-dropping how much perfectly good food is thrown away — from “ugly” (but quite eatable) vegetables rejected by grocers 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 producer of greenhouse gases in the world.”
If that’s hard to understand, let’s 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, it's more like 12 bones of donated strawberries nearing their last days. Curtin is CEO of DC Central Kitchen in Washington, D.C., which recovers food and turns it into healthy meals. Last year it recovered more than 807,500 pounds of food by taking donations and collecting blemished (有瑕疵的) produce that otherwise would have rotted in fields. And the strawberries Volunteers will wash, cut, and freeze or dry them for use in meals down the road.
Such methods seem obvious, yet so often we just don’t think. “Everyone can play a part in reducing waste, whether by not purchasing more food than necessary in your weekly shopping or by asking restaurants to not include the side dish you won’t eat,” Curtin says.

At the start of the 20th century, an American engineer named John Elfreth Watkins made predictions about life today. His predictions about slowing population growth, mobile phones and increasing height were close to the mark. But he was wrong in one prediction: that everybody would walk 10 miles a day.
Today, in Australia, most children on average fall 2,000 steps short of the physical activity they need to avoid being overweight. In the early 1970s, 40 per cent of children walked to school, while in 2010, it was as low as 15 per cent.
The decline is not because we have all become lazy. Families are pressed for time, many with both parents working to pay for their house, often working hours not of their choosing, living in car-dependent neighborhoods with limited public transport.
The other side of the coin is equally a deprivation: for health and well-being, as well as lost opportunities (机会) for children to get to know their local surroundings. And for parents there are lost opportunities to walk and talk with their young scholar about their day.
Most parents will have eagerly asked their child about their day, only to meet with a “good”, quickly followed by “I’m hungry”. This is also my experience as a mother. But somewhere over the daily walk more about my son’s day comes out. I hear him making sense of friendship and its limits. This is the unexpected and rare parental opportunity to hear more.
Many primary schools support walking school-bus routes (路线), with days of regular, parent-accompanied walks. Doing just one of these a few times a week is better than nothing. It can be tough to begin and takes a little planning — running shoes by the front door, lunches made the night before, umbrellas on rainy days and hats on hot ones — but it’s certainly worth trying.

The other side of the coin is equally a deprivation: for health and well-being, as well as lost opportunities (机会) for children to get to know their local surroundings. And for parents there are lost opportunities to walk and talk with their young scholar about their day.
Most parents will have eagerly asked their child about their day, only to meet with a “good”, quickly followed by “I’m hungry”. This is also my experience as a mother. But somewhere over the daily walk more about my son’s day comes out. I hear him making sense of friendship and its limits. This is the unexpected and rare parental opportunity to hear more.
Many primary schools support walking school-bus routes (路线), with days of regular, parent-accompanied walks. Doing just one of these a few times a week is better than nothing. It can be tough to begin and takes a little planning — running shoes by the front door, lunches made the night before, umbrellas on rainy days and hats on hot ones — but it’s certainly worth trying.

24. Why does the author mention Watkins’ predictions in the first paragraph

26. Why does the author find walking with her son worthwhile
（2021年1月B）
At the start of the 20th century, an American engineer named John Elfreth Watkins made predictions about life today. His predictions about slowing population growth, mobile phones and increasing height were close to the mark. But he was wrong in one prediction: that everybody would walk 10 miles a day.
Today, in Australia, most children on average fall 2,000 steps short of the physical activity they need to avoid being overweight. In the early 1970s, 40 per cent of children walked to school, while in 2010, it was as low as 15 per cent.

The elderly residents (居民) in care homes in London are being given hens to look 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 people’s 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 of 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 letting the hens out and down there again at night to see they’ve gone to bed.”
“It’s 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. I’m enjoying the creative activities, and it feels great to have done something useful.”
There are now 700 elderly people looking after hens in 20 care homes in the North East, and the charity has been given financial support to roll it out countrywide.
Wendy Wilson, extra care manager at 60 Penfold Street, one of the first to embark on the project, said: “Residents really welcome the idea of the project and the creative sessions. We are looking forward to the benefits and fun the project can bring to people here.”
Lynn Lewis, director of Notting Hill Pathways, said: “We are happy to be taking part in the project. It will really help connect our residents through a shared interest and creative activities.”

Milwaukee, Wisconsin, is road testing a new way to keep winter roads ice-free – by spreading on them cheese brine, the salty liquid used to make soft cheese, like mozzarella.
Wisconsin, also called "America's Dairyland," is famous for its cheese. The state produced 2.8 billion pounds of cheese last year! a result, there was a lot of leftover cheese brine. Disposing of(处置)the brine can be expensive. So what should cheese makers do with the waste
Normally, towns use rock salt to de-ice streets. The salt lowers waters' freezing point, causing ice to melt(融化). But using cheese brine could help both cheese producers and cities save money, while keeping roads safe. Cheese brine has salt in it, which, like the rock salt, helps lower water's freezing point.
In addition to saving money, cheese brine could also be a more environment-friendly option. Many people suspect that all the rock salt used every winter is harming the environment.
Rock salt is made of sodium chloride, the sane con-pound (化合物)in ordinary table salt. Sounds harmless, right But while you probably add only a small amount of salt to your food, road crews spread about 20 million tons of salt on U.S. Roads every year!
The chemical washes off roads and goes into the ground. There it can pollute drinking water, harm plants. and eat away soil. By spreading cheese brine on streets before adding a layer of rock salt, Milwaukee may be able to cut its rock salt use by 30 percent.
Cheese brine has a downside too – a shell similar to that of bad milk. "I don't really mind it," Emil Norby told Modern Farmer magazine. He works for one of Wisconsin's county highway commissions and came up with the idea of using cheese brine. "Our roads smell like Wisconsin!" he said.

According to the Solar Energy Industry Association, the number of solar panels installed (安 装) has grown rapidly in the past decade, and it has to grow even faster to meet climate goals. But all of that growth will take up a lot of space, and though more and more people accept the concept of solar energy, few like large solar panels to be installed near them.
Solar developers want to put up panels as quickly and cheaply as possible, so they haven't given much thought to what they put under them. Often, they'll end up filling the area with small stones and using chemicals to control weeds. The result is that many communities, especially in farming regions, see solar farms as destroyers of the soil.
“Solar projects need to be good neighbors,” says Jordan Macknick, the head of the Innovative Site Preparation and Impact Reductions on the Environment(InSPIRE) project. “They need to be protectors ofthe land and contribute to the agricultural economy.” InSPIRE is investigating practical approaches to “low-impact” solar development, which focuses on establishing and operating solar farms in a way that is kinder to the land. One of the easiest low-impact solar strategies is providing habitat for pollinators(传粉昆虫).
Habitat loss, pesticide use, and climate change have caused dramatic declines in pollinator populations over the past couple of decades, which has damaged the U.S. agricultural economy. Over 28 states have passed laws related to pollinator habitat protection and pesticide use. Conservation organizations put out pollinator-friendliness guidelines for home gardens, businesses, schools, cities—and now there are guidelines for solar farms.
Over the past few years, many solar farm developers have transformed the space under their solar panels into a shelter for various kinds of pollinators, resulting in soil improvement and carbon reduction. “These pollinator-friendly solar farms can have a valuable impact on everything that's going on in the landscape,” says Macknick.

（2020年7月B）The traffic signals along Factoria Boulevard in Bellevue, Washington, generally don't flash the same length of green twice in a row, especially at rush hour. At 9:30am, the full red/yellow/green signal cycle might be 140 seconds. By 9:33am, a burst of additional traffic might push it to 145 seconds. Less traffic at 9:37am could push it down to 135. Just like the traffic itself, the timing of the signals changes.
That is by design. Bellevue, a fast-growing city just east of Seattle, uses a system that is gaining popularity around the US: intersection(十字路口) signals that can adjust in real time to traffic conditions. These lights, known as adaptive signals, have led to significant declines in both the trouble and cost of travels between work and home. “Adaptive signals can make sure that the traffic demand that is there is being addressed, ” says Alex Stevanovic, a researcher at Florida Atlantic University.
For all of Bellevue’s success, adaptive signals are not a cure-all for jammed roadways. Kevin Balke, a research engineer at the Texas A&M University Transportation Institute, says that while smart lights can be particularly beneficial for some cities, others are so jammed that only a sharp reduction in the number of cars on the road will make a meaningful difference. “It’s not going to fix everything, but adaptive signals have some benefits for smaller cities,” he says.
In Bellevue, the switch to adaptive signals has been a lesson in the value of welcoming new approaches. In the past, there was often an automatic reaction to increased traffic: just widen the roads, says Mark Poch, the Bellevue Transportation Department’s traffic engineering manager. Now he hopes that other cities will consider making their streets run smarter instead of just making them bigger.
