【推荐1】Life can be hard for teens. Negative (消极的)feelings such as sadness are common for them. But for some teens, those feelings take a more extreme turn. Their negative feelings don’t come and go. Instead, those feelings can point to a disease called depression (抑郁)—one that may require treatment.

Some kids suffering depression stay away from friends and family members. Some others respond with anger. Some teens may skip school or stop eating or sleeping. Some may start drinking wine or taking drugs. However, teachers, parents or even a teen’s close friends may find it hard to tell whether these kinds of behavior are just part of being a teen or signs of something truly serious.

Each year, about 5, 000 Americans between the ages of 15 and 24 take their own lives. And there is a link between mental (精神的) illness and the teens’ act of killing themselves. That’s according to the American Academy of Child and Adolescent Psychiatry, based in Washington, D. C. “Most children and teenagers who try to take their own lives have a serious mental health disorder, usually depression,” it says. And as a disease, depression can last for ten years or longer.

Even depressed teens themselves may not realize they have this problem. More than three million Americans between the ages of 12 and 17 experienced depression in 2016. However, most likely went untreated. A 2001 study by researchers at Harvard University and Yale University found that half of all the teens with depression didn’t get help until they became adults. And only one in three had been found suffering depression by their primary care doctor, another study reported. So how can people tell the behavior showing growing mental pains from a sign of the disease? One key is a sharp change in behavior. Another warning sign: persistence (持续)in that new behavior—meaning that it sticks around for two weeks or longer.

Luckily, the American Academy of Pediatrics, or AAP, has now asked its doctors to start screening preteens and teens for signs of depression. And AAP is also asking its doctors to receive mental-health training. It wants them to become more aware(有意识的)of the signs of depression. Where depression is found, doctors will then work with mental-health professionals to find out how to treat it so that the patients can feel good again. The new guidelines can make it easier for teens to get the help they need.

With the number of infections surpassing 20,000, the United States now leads the world in monkeypox cases. Like a replay of the COVID-19 outbreak, Black and Hispanic Americans in the country still bear an improper burden in the public health emergency. They make up the majority of monkeypox cases but are underrepresented in vaccine distribution.

Signs show the number of infections in the country is slowing, but racial divides are worsening in monkeypox cases and vaccine access. Over 38 percent of the monkeypox infections are among Black people, who represent only 13.6 percent of the country’s population of 335 million. Similarly, Hispanic or Latino people account for 28.3 percent of the total cases as of Sept. 3 but are only 19 percent of the U.S. population. By contrast, the share of White people in the total contracted cases fell heavily from 75 percent as of May 20 to 27.5 percent, according to the U.S. Centers for Disease Control and Prevention.

Similar trends in racial gaps can be seen among U.S. states and cities with the most monkeypox cases. For example, Black or African American residents make up 55 percent of all monkeypox cases but just 24 percent of vaccinations in Philadelphia, city data showed. White Philadelphians make up 24 percent of cases but have received 56 percent of first shots.

“Unfortunately, it’s not that surprising,” said Mark Abdelmalek, a dermatologist who has treated monkeypox patients. “History kind of repeats itself. We see unfair health treatment across many aspects of medicine, and to think that this wouldn’t be one of them is a little naive.” The dermatologist added, “I mean we saw it with COVID. It speaks to the fact that we have a lot of work to do to meet people where they are.”

【推荐1】You might feel burned out after solving a difficult math problem or studying for a whole day. Are our brains really “burning” when we spend a lot of time thinking? In fact, our brains never stop burning calories, even if we aren't thinking about anything.

Our brains are powered by glucose, a kind of sugar that can be found in carbohydrates (碳水化合物) like rice and noodles. The glucose goes to the brain through the bloodstream. It powers the neurons (神经元) in our brains. Since our brain never really rests, it is burning energy in the form of glucose all the time. Even when we sleep, our brain needs energy to keep our body's basic functions (功能) working. These include breathing, digesting, and keeping the body warm.

The brain uses up 20 to 25 percent of the body’s total energy. That’s 350 calories per day for woman and 450 for man. When you are five or six years old, your brain uses up to 60 percent of the body's energy, according to Live Science.

   When we are thinking hard, the brain burns more calories . In one experiment, researchers found that people who worked on a hard task on a computer ate around 200 more calories than those who were resting. That explains why you feel hungry and eat more after taking exams or studying for a long time.

【推荐2】People living on parts of the south coast of England face a serious problem. In 1993, the owners of a large hotel and of several houses discovered, to their horror, that their gardens had disappeared overnight. The sea had eaten into the soft limestone （石灰岩） cliffs on which they had been built. While experts were studying the problem, the hotel and several houses disappeared altogether, sliding down the cliff and into the sea.

Erosion（侵蚀）of the white cliffs along the south coast of England has always been a problem but it has become more serious in recent years. Dozens of homes have had to be abandoned as the sea has crept farther and farther inland. Experts have studied the areas most affected and have drawn up a map for local people, forecasting the year in which their homes will be swallowed up by the hungry sea.

Angry owners have called on the Government to erect sea defenses to protect their homes. Government surveyors have pointed out that in most cases, this is impossible. New sea walls would cost hundreds of millions of pounds and would merely make the waves and currents go further along the coast, shifting the problem from one area to another. The danger is likely to continue, they say, until the waves reach an inland area of hard rock which will not be eaten as limestone is. Meanwhile, if you want to buy a cheap house with an uncertain future, apply to a house agent in one of the threatened areas on the south coast of England. You can get a house for a knockdown price but it may turn out to be a knockdown home.

La Tomatina(Spain)

Last Wednesday of August

This “largest food fight in the world” is believed to have been started with a tomato—but it certainly didn’t end with just one. Now, more than 50,000 people pack the streets of Bunol, Spain, armed with cheap tomatoes, ready to pelt friends and strangers alike. Gloves and safety glasses are suggested as the battle can get quite heated, even though it lasts just an hour. While past years allowed anyone and everyone to take part, the large number of attendees pushed town officials to require tickets.

National Beer Day(Iceland)

March 1

It’s no secret that Icelanders are fond of a bit of partying. After all, when there are days when the sun won’t stop shining, it makes sense to throw a few back to celebrate. However, it wasn’t that long ago(1989) that Iceland was still under a form of prohibition(禁酒令) and unable to sell beer. When the laws were passed to make beer legal on March 1,1989, Icelanders were excited and have since celebrated National Beer Day each March 1 with pub dances and other celebrations that last until the early hours of the morning. Beer has since become the most popular drink in the country.

Lopburi Monkey Banquet(盛宴)(Thailand)

Last Sunday in November

If you’ve ever come in close contact with monkeys, you know that they’re often a bit troublesome, taking a sandwich from your hand without warning or breaking into your hotel minibar if you forget to lock the doors(true story). However, in 1989, in Lopburi, Thailand, a local innkeeper decided to feed the monkeys a banquet as they’re also believed to bring good luck. Thus, a tradition was born and the banquet has grown each year. As the monkeys run into the banquet, they soon get a bit excited and start dancing on the tables and throwing food. For visitors, it’s a highly enjoyable sight—just be sure to wear clothes that you don’t mind being decorated by the monkeys.
