Most climate studies on projected heat stress have focused too much on extreme heat but did not consider the role of humidity, which is another key driver. “When we look at the risks of a warmer planet, we need to pay particular attention to the combined effects of extreme heat and humidity, which are especially dangerous to human health.” said Robert E. Kopp, director of the Rutgers Institute of Earth, Ocean, and Atmospheric Sciences.

Rising global temperatures are increasing exposure to heat stress, which harms human health. Heat stress is caused by the body’s inability to cool down properly through sweating. Body temperature can rise rapidly, and high temperatures may damage the brain and other vital organs. What’s more, heat stress can result in heatstroke (中暑), which is the most serious heat-related illness, can kill or cause permanent disability without emergency treatment.

Annual exposure to extreme heat and humidity above safety guidelines will be projected to affect areas that are currently home to about 500 million people, if the planet warms by 1.5℃ and nearly 800 million at 2℃. The planet has already warmed by about 1.2℃ above late 19th century levels.

An estimated 1.2 billion people would be affected with 3℃ of warming, as expected by the end of this century under current global policies. That’s nearly four times the number of people affected today, and nearly 12 times the number who were affected in no industrial age.

【推荐2】Migraine is a disease that has a number of symptoms, including head pain that can stick around from four hours to several days. While migraines can occur partly because of genetic factors, attacks may happen by chance, set off by a cause in the environment.

One common cause is food, and some common dietary causes include alcohol, salt, sugar, chocolate, and caffeine. But there are many others, and scientists continue to identify more. For instance, a Brazilian study found that watermelons brought on a headache within minutes in about 30 percent of the participants.

Some of the newest research is looking at which foods and what kinds of diets can prevent or lessen migraines. A new study published last year by a team of researchers found that a diet higher in fish oils rather than vegetable oils helped people ease their headaches. In the study, those on a diet lower in vegetable oil and higher in fatty fish had a 30 to 40 percent reduction in total headache hours per day, serious headache hours per day, and overall headache days per month compared to the control group.

Tanya Kamka had suffered weekly migraines for most of her life. Then, in her 50s, she joined the NIH diet trial and increased her intake of fish. After only a few months, “I haven’t had a migraine, not even a mild one, in over two years,” she says.

For others, the solution comes from plants, not fish. A 60-year-old man joined a study on the food-migraine link and turned to a diet, which includes a lot of dark, leafy greens. After two months he was experiencing only one migraine a month instead of the 18 to 24 a month he’d suffered before.

Clearly, people with migraines react to food in very different ways. What works for one person may not work for another.

【推荐3】Millions of people pass through the gates of Disney’s entertainment parks each year. What makes these places an almost universal attraction? What makes foreign kings and queens and other important people want to visit these Disney parks? Well，one reason is the way they’re treated once they get there.The people at Disney go out of their way to serve their “guests”，as they prefer to see that they enjoy themselves.

All new employees，from vice presidents to part­time workers，begin their employment by attending Disney University and taking “TraditionsⅠ”. Here，they learn about the company’s history，how it is managed，and why it is successful. They are shown how each department relates to the whole. All employees are shown how their part is important in making the park a success.

After passing “TraditionsⅠ”，the employees go on to do more specialised training for their specific(具体的) jobs. No detail(细节) is missed. A simple job like taking tickets requires four eight­hour days of training. When one ticket taker was asked why it took so much training for such a simple，ordinary job，he replied，“What happens if someone wants to know where the restrooms are，when the parade starts or what bus to take back to the campgrounds?We need to know the answers or where to get them quickly. Our constant aim is to help our guests enjoy the party.”

Even Disney’s managers get involved in the daily management of the parks. Every year，the managers leave their desks and business suits and put on special service clothes. For a full week，the bosses sell hot dogs or ice cream，take tickets or drive the monorail，and take up any of the 100 jobs that make the entertainment park come alive. The managers agree that this week helps them to see the company’s goals more clearly.

All these efforts to serve the public well have made Walt Disney productions famous. Disney is considered by many as the best mass service provider in America or the world. As one long­time business observer once said，“How Disney treats people，communicates with them，rewards them，is in my view the very reason for his fifty years of success. ..I have watched，very carefully and with great respect and admiration，the theory and practice of selling satisfaction and serving millions of people on a daily basis，successfully. It is what Disney does best.”

【推荐1】In Europe, many people make friends between their countries through town twinning. Town or city twinning means two towns in different countries agree and decide to become “twins” with a sister city relationship.

The people find pen friends in the twin town. They exchange newspapers and stamps. The school teachers discuss teaching methods with the teachers in the twin town. Officials visit the twin town for celebrations. Ordinary people travel to the twin town, too, but not very often if it is far away.

Sometimes, schools even exchange their classes for two or three weeks! For example, German middle school students study for a while at the school in their twin town in Britain, staying with British families. A few months later, their British friends come to study in Germany.

Many British towns are so pleased with the results of the twinning that they set out to find more than one twin town! Tonbridge, a small town, for example, has twin towns in both Germany and France.

Town twinning can help make friends. It helps students improve their language skills, and also helps people to understand the differences between nations.
