3 . A teenager from the UK almost died because of an addiction to unhealthy exercise.

Lisa Fouweather, 19, was so addicted to working out that she ran half marathons before breakfast. She started to practice running, hoping to become excellent at her running club, but quickly became addicted.

She was hardly eating to keep in shape. The teen’s meals would only include a few pieces of food from her “safe foods” list which was mainly fruit and vegetables. She would avoid anything containing sugar or fat. “I would throw my orange juice and bread out of the window when my parents left the room,” she said. At one point, her weight dropped to just 75 pounds — around 34 kg.

This helped to improve her running in the short-term when, in fact, her whole life was falling apart. It affected her education as she would turn up late to school every day to finish her morning running. She said, “Six-mile runs became half marathons, all on an empty stomach before breakfast. Upon my return, I would eat only fruit.”

However, although warned by her parents, Lisa refused to admit she had a problem and wouldn’t give up her way of working out until one day she had a heart attack after her running and was rushed to hospital, where she was diagnosed with anorexic (厌食症) and banned from exercise. “I was told that I could have died because my heart was under great pressure.” She was given dieting advice by doctors to help treat her eating disorders. Thanks to hard work and professional help, she managed to put a stop to her extreme exercise and dieting and has been in recovery for nearly three years.

Lisa said, “I want people who are going through the same problem as I did to know that there is help and support out there, and don’t wait until you’re at breaking point to seek that help.”

4 . Koalas live in the eucalyptus （枝树）forests of southeastern and eastern Australia. They rely on the eucalyptus tree for both habitat and food. In fact, they seldom leave these trees. When not sleeping, they're usually eating. They can eat more than a pound of eucalyptus leaves a day. Eucalyptus is poisonous, so the koala's digestive （消化的）system has to work hard to digest it, breaking down the poisons and taking in the limited nutrients （营养）.That's why koalas sleep for 18 to 22 hours a day — they get very little energy from their diet.

Koala numbers decreased in the late 19th and early 20th century from hunting for their fur. Now they face serious threats from habitat loss. Land clearing and bush fires-especially the 2019-2020 Australia Bushfire Season-have destroyed much of the forest they live in. Koalas are easy to be affected by climate change. Increasing carbon dioxide in the atmosphere is decreasing the nutritional quality of eucalyptus leaves and causing longer, more serious droughts and wildfires. In response to drought, koalas are forced to stop sleeping and come down from the trees to find water, putting them at a higher risk of being killed.

Koalas have been identified by the Australian government as one of the 113 animals requiring urgent （紧急的）help. Ensuring there's the right kind of forest for them to return to is extremely urgent. State governments should create new koala reserves and persuade landowners not to cut down eucalyptus trees. Meanwhile, getting the public to understand koalas' living habits and their health will throw light on koala biology, which helps to develop plans to better protect the species.

5 . Standing on the ruins（废墟）after the fire where his house had been, Peter Ruprecht admitted that he was not sure how or when to rebuild. He was still shocked by what Australia's increasingly changeable climate had already delivered: first a drought, then a destructive bush fire, then a foot of rain from a storm.

"It's unstoppable," said Mr. Ruprecht, a former dairy farmer. "We speak about the warmth of Mother Nature, but nature can also be vicious and wild and unforgiving."

Australia's' hellish（地狱的）fire season has eased（缓和）, but its people are facing more than a single disaster. With floods destroying homes not far from where fires recently spread, they are facing a cycle of what scientists call "compound extremes": one climate disaster strengthening the next.

Warmer temperatures do more than just dry out the land. They also heat up the atmosphere, which means clouds hold more moisture（水汽）for longer periods of time. So droughts get worse, giving way to fires, then to heavy rains that the land is too dry to absorb.

Many Australians in disaster zones complain that their government, after ignoring climate change for years, has not yet to draw up recovery plans that are clear and that take future threats into account.

At the same time, the economic costs of a changing climate are rising quickly. Philip Lowe, the governor of the Reserve Bank of Australia, warned recently that Australia was already paying a price, and that it would only go up.

7 . Animal rights activists respect animals because they understand animals have a place in the world. Zoos, especially the ones that are doing everything right, become a headache for the animal rights activists.

Zoo supporters argue that they save endangered species and educate the public, but many animal rights activists believe the costs are more than the benefits, and the violation(违反) of the rights of the individual animals is unreasonable. Roadside zoos, petting zoos, and smaller animal exhibitors tend to offer narrow space for the animals, keeping them in pens or cages. Sometimes, a tiger or bear will live with cold concrete（混凝土）and metal bars for their entire lives. Larger, trusted zoos try to avoid these operations by offering excellent treatment to the animals. However, to animal rights activists, the problem is not how well the animals are treated, but whether we have a right to limit (限制）them for our delight or “education”.

To zoo supporters, by bringing people and animals together, zoos educate the public and promote an appreciation of the animals, encouraging people to protect the animals. Zoos save endangered species by bringing them into a safe environment, where they are protected from poachers(偷猎者), habitat loss, hunger, and predators(捕食者). Many zoos also have various programs for endangered species. In the wild, these individuals might have trouble finding mates and multiplying(繁殖). A good zoo provides an enriched habitat in which the animals are never bored, are well cared for, and have plenty of space. Besides, zoos are a tradition, and a visit to a zoo is a healthy, family activity.

In the case of zoos, both sides—animal rights activists and zoo supporters will argue that their side saves animals. Whether or not zoos benefit the animal community, they certainly do make money. As long as there is need for zoos, they will continue to exist. We can start by making sure that conditions are the best possible for the animals who are limited to zoos.

8 . Who're happier, men or women?Research shows it's a complex question and that asking whether males or females are happier isn't really that helpful, because basically, happiness is different for women and men.

Women's happiness has been declining for the past 30 years, according to recent statistics.And research shows that women are twice as likely to experience depression compared with men.Gender（性别） differences in depression are well confirmed and studies have found that biological, psychological and social factors contribute to the difference.

Early studies on gender and happiness found men and women were socialized to express different feelings.Women are more likely to express happiness, warmth and fear, which help with social bonding and appear more consistent with the traditional role as a primary caregiver, while men display more anger, pride and disrespect, which are more consistent with a protector and provider role.

Recent research suggests that these differences are not just socially, but also genetically related.Studies have looked into these findings further and discovered that females use more areas of the brain containing mirror neurons（镜像神经元）than males when they process feelings.Mirror neurons allow us to experience the world from other people's view, to understand their actions and intentions.This may explain why women can experience deeper sadness.Women tend to experience more negative feelings, such as more guilt, shame and to a lesser degree, embarrassment.

Psychologically it seems men and women differ in the way they process and express feelings.With the exception of anger, women experience feelings more strongly and share their feelings more openly with others.Studies have found in particular that women express more appreciation﹣which has been linked to greater happiness.This supports the theory that women's happiness is more dependent on relationships than men's.

9 . Those days of sucking (吮吸) up the sides of your rapidly melting (融化) ice cream may soon be over. Researchers have discovered a natural protein that could be added to everyone’s favorite summertime snack to keep it solid for longer, according to a press release from the University of Edinburg in Scotland.

Most people know that, at its most basic, ice cream is made of milk and sugar. But it has other ingredients that give it a solid consistency (黏稠度) — a fat (often oil), air bubbles, and ice crystals. The protein that the researchers discovered, called BsIA, coats all three of them to slow down the rate at which the ice melts and the air escapes. In one study of the protein, published earlier this year, the researchers call BsIA a “raincoat” that can act as a film to keep everything inside it for just a little longer. That same quality prevents big pieces of ice crystals from forming, which can happen if you leave ice cream in the fridge for too long.

BsIA is found in bacteria called Bacillus subtilis that is common in soil, and is already present in some foods. So adding the protein to ice cream wouldn’t bring the same sorts of long-term health concerns as would artificial ingredients (人造添加剂). The researchers note that producers could also add BsIA to ice cream to reduce their fat and sugar content.

Though the researchers have published two papers about BsIA and have tested it in the lab, they are staying quiet on the most recent data they collected, as the Washington Post notes. Importantly, the researchers make no mention about how the new ingredient might affect ice cream’s taste or how much we might enjoy eating it. What’s the good of long-lasting ice cream if you don’t even like it? But it might not be too long before you can try it out for yourself; ice cream with BsIA might be available within three to five years.
