1 . 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.

2 . PRACTITIONERS
| Jacqueline Felice de Almania (c.1322) highlights the suspicion that women practicing medicine faced. Born to a Jewish family in Florence, she moved to Paris where she worked as a physician and performed surgery. In 1322 she was tried for practicing unlawfully. In spite of the court hearing testimonials (证明) of her ability as a doctor, she was banned from medicine. | James Barry (c.1789 — 1865) was born Margaret Bulkley in Ireland but, dressed as a man, she was accepted by Edinburgh University to study medicine. She qualified as a surgeon in 1813, then joined the British Army, serving overseas. Barry retired in 1859, having practiced her entire medical profession living and working as a man. |
| Tan Yunxian (1461 — 1554) was a Chinese physician who learned her skills from her grandparents. Chinese women at the time could not serve apprenticeships (学徒期) with doctors. However, Tan passed the official exam. Tan treated women from all walks of life. In 1511, Tan wrote a book, Sayings of a Female Doctor, describing her life as a physician. | Rebecca Lee Crumpler (1831 — 1895) worked as a nurse for eight years before studying in medical college in Boston in 1860. Four years later, she was the first African American woman to receive a medical degree. She moved to Virginia in 1865, where she provided medical care to freed slaves. |

3 . Grizzly bears, which may grow to about 2.5 m long and weigh over 400 kg, occupy a conflicted corner of the American psyche — we revere (敬畏) them even as they give us frightening dreams. Ask the tourists from around the world that flood into Yellowstone National Park what they most hope to see, and their answer is often the same: a grizzly bear.
“Grizzly bears are re-occupying large areas of their former range,” says bear biologist Chris Servheen. As grizzly bears expand their range into places where they haven’t been seen in a century or more, they’re increasingly being sighted by humans.
The western half of the US was full of grizzlies when Europeans came, with a rough number of 50,000 or more living alongside Native Americans. By the early 1970s, after centuries of cruel and continuous hunting by settlers, 600 to 800 grizzlies remained on a mere 2 percent of their former range in the Northern Rockies. In 1975, grizzlies were listed under the Endangered Species Act.
Today, there are about 2,000 or more grizzly bears in the US. Their recovery has been so successful that the US Fish and Wildlife Service has twice attempted to delist grizzlies, which would loosen legal protections and allow them to be hunted. Both efforts were overturned due to lawsuits from conservation groups. For now, grizzlies remain listed.
Obviously, if precautions (预防) aren’t taken, grizzlies can become troublesome, sometimes killing farm animals or walking through yards in search of food. If people remove food and attractants from their yards and campsites, grizzlies will typically pass by without trouble. Putting electric fencing around chicken houses and other farm animal quarters is also highly effective at getting grizzlies away. “Our hope is to have a clean, attractant-free place where bears can pass through without learning bad habits,” says James Jonkel, longtime biologist who manages bears in and around Missoula.

4 . With gas prices rising and airport security lines snaking longer than ever, why not book your next domestic vacation on a train? Compared to other alternatives, it’s comfortable and relaxing. Here is some advice on how to make a trip by rail as pleasant as possible.
Plan ahead. Most long-distance trains, especially the sleeping car accommodations, sell out very quickly.
Use a travel agent. Consider turning your travel plan over to a travel agent and letting him double-check all the details, make suggestions, and then handle the actual reservations. A good one can sometimes find you discounted tickets.
Bring a blanket. When you’re riding on trains, you won’t be provided with a blanket for free, even if your trip is an overnight one.
Arrive early. Most trains operate just once a day and some run only three times a week, so missing yours can be a disaster.
Have fun.
| A．Train trips aren’t for impatient types. |
| B．You’ll have views from both sides of the train. |
| C．The temperature on rail cars is often hard to control. |
| D．That’s particularly true during busy summer months. |
| E．You might have to wait longer than 24 hours to catch the next one. |
| F．Chances are the cost will be a lot less than the cost of one bedroom. |
| G．He may also book you in a sleeping car that’s right next to the diner. |
5 . Tricks To Becoming A Patient Person
Here’s a riddle: What do traffic jams, long lines and waiting for a vacation to start all have in common? There is one answer.
In the Digital Age, we’re used to having what we need immediately and right at our fingertips. However, research suggests that if we practiced patience, we’d be a whole lot better off. Here are several tricks.
●Practice gratitude (感激)
Thankfulness has a lot of benefits: Research shows it makes us happier, less stressed and even more optimistic.
● Make yourself wait
Instant gratification (满足) may seem like the most “feel good” option at the time, but psychology research suggests waiting for things actually makes us happier in the long run. And the only way for us to get into the habit of waiting is to practice.
●
So many of us have the belief that being comfortable is the only state we will tolerate, and when we experience something outside of our comfort zone, we get impatient about the circumstances. You should learn to say to yourself, “
| A．Find your causes |
| B．Start with small tasks |
| C．Accept the uncomfortable |
| D．All this adds up to a state of hurry |
| E．It can also help us practice more patience |
| F．This is merely uncomfortable, not intolerable |
| G．They’re all situations where we could use a little extra patience |
I was invited to a cookout on an old friend’s farm in western Washington. I parked my car outside the farm and walked past a milking house which had apparently not been used in many years. A noise at a window caught my attention, so I entered it. It was a hummingbird (蜂鸟), desperately trying to escape. She was covered in spider-webs (蛛网) and was barely able to move her wings. She ceased her struggle the instant I picked her up.
With the bird in my cupped hand, I looked around to see how she had gotten in. The broken window glass was the likely answer. I stuffed a piece of cloth into the hole and took her outside, closing the door securely behind me.
When I opened my hand, the bird did not fly away; she sat looking at me with her bright eyes. I removed the sticky spider-webs that covered her head and wings. Still, she made no attempt to fly. Perhaps she had been struggling against the window too long and was too tired? Or too thirsty?
As I carried her up the blackberry-lined path toward my car where I kept a water bottle, she began to move. I stopped, and she soon took wing but did not immediately fly away.
Hovering (悬停), she approached within six inches of my face. For a very long moment, this tiny creature looked into my eyes, turning her head from side to side. Then she flew quickly out of sight.
During the cookout, I told my hosts about the hummingbird incident. They promised to fix the window. As I was departing, my friends walked me to my car. I was standing by the car when a hummingbird flew to the center of our group and began hovering. She turned from person to person until she came to me. She again looked directly into my eyes, then let out a squeaking call and was gone. For a moment, all were speechless. Then someone said, “She must have come to say goodbye.”

The twins were filled with excitement as they thought of the surprise they were planning for Mother’s Day. How pleased and proud Mother would be when they brought her breakfast in bed. They planned to make French toast and chicken porridge. They had watched their mother in the kitchen. There was nothing to it. Jenna and Jeff knew exactly what to do.
The big day came at last. The alarm rang at 6 a.m. The pair went down the stairs quietly to the kitchen. They decided to boil the porridge first. They put some rice into a pot of water and left it to boil while they made the French toast. Jeff broke two eggs into a plate and added in some milk. Jenna found the bread and put two slices into the egg mixture. Next, Jeff turned on the second stove burner to heat up the frying pan. Everything was going smoothly until Jeff started frying the bread. The pan was too hot and the bread turned black within seconds. Jenna threw the burnt piece into the sink and put in the other slice of bread. This time, she turned down the fire so it cooked nicely.
Then Jeff noticed steam shooting out of the pot and the lid starting to shake. The next minute, the porridge boiled over and put out the fire. Jenna panicked. Thankfully, Jeff stayed calm and turned off the gas quickly. But the stove was a mess now. Jenna told Jeff to clean it up so they could continue to cook the rest of the porridge. But Jeff’s hand touched the hot burner and he gave a cry of pain. Jenna made him put his hand in cold water. Then she caught the smell of burning. Oh dear! The piece of bread in the pan had turned black as well.

Living in Iowa and trying to become a photographer specializing in landscape (风景) can be quite a challenge, mainly because the corn state lacks geographical variation.
Although landscapes in the Midwest tend to be quite similar, either farm fields or highways, sometimes I find distinctive character in the hills or lakes. To make some of my landscape shots, I have traveled up to four hours away to shoot within a 10-minute time frame. I tend to travel with a few of my friends to state parks or to the countryside to go on adventures and take photos along the way.
Being at the right place at the right time is decisive in any style of photography. I often leave early to seek the right destinations so I can set up early to avoid missing the moment I am attempting to photograph. I have missed plenty of beautiful sunsets/sunrises due to being on the spot only five minutes before the best moment.
One time my friends and I drove three hours to Devil’s Lake, Wisconsin, to climb the purple quartz (石英) rock around the lake. After we found a crazy-looking road that hung over a bunch of rocks, we decided to photograph the scene at sunset. The position enabled us to look over the lake with the sunset in the background. We managed to leave this spot to climb higher because of the spare time until sunset. However, we did not mark the route (路线) so we ended up almost missing the sunset entirely. Once we found the place, it was stressful getting lights and cameras set up in the limited time. Still, looking back on the photos, they are some of my best shots though they could have been so much better if I would have been prepared and managed my time wisely.
