Many studies have shown that the company of pets can help lower blood pressure and raise chances of recovering from a heart attack, reduce loneliness and help control body weight.

    Any pet owner will tell you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress levels and blood pressure in people (half of them were pet owners) while they performed 5 minutes of mental arithmetic (算术) or held a hand in ice water. People completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems that people feel more relaxed around pets, says Allen, who thinks it may be because pets don't judge.

    A study reported last fall suggests that having a pet dog may also have an effect on your body weight. Researchers at Northwestern Memorial Hospital spent a year studying two groups of fat people who were put on a diet-and-exercise program: one group with pet dogs, and the other without. On average，dog owners lost about 11 pounds，or 5% of their body weight; While those without dogs lost about 8 pounds. The pet owners, said researchers, got more exercise overall (mostly with their dogs) and found it worth doing.

    The law says women should have the chance of doing the same jobs as men and earn the same as them. The reality is very different. Women lose because, 25 years after the Equal Pay Act, many of them still get paid less than men. They lose because they do lower-paid jobs which men just won't consider. And they lose because they are the ones who interrupt a career to have children.  All this is reported in an independent study ordered by the Government's women's unit. The biggest problem isn't equal pay in workplaces such as factories. It is the sort of work women do.

    Make a list of low-paid-jobs, then consider who does them. Try nurses, secretaries, cleaners, clerks, teachers in primary schools, dinner ladies and child-care helpers. Not a lot of men among that group, are there? Yet some of those jobs are really important. Surely no one would deny that about nurses and teachers, for a start. So why do we reward the people who do them so poorly? There can be only one answer—because they are women. This is not going to be put right overnight. But the government, which employs a lot of them, and other bosses have to make a start.

    It is disgraceful (可耻的) that we have gone into the 21st century still treating women like second-class citizens.

    A sea turtle named Herman, an octopus called Octavia, and a seal named Lidia all spent this summer at the Smithsonian's National Zoo in Washington, D.C. But unlike the zoo's other residents, they are not real animals. These creatures are actually huge sculptures and they're made entirely out of plastic trash from the ocean.

    These giant artworks, along with 14 others, are part of a traveling exhibit called “Washed Ashore: Art to Save the Sea”. The Washed Ashore project, led by artist Angela Haseltine Pozzi, works to raise awareness about the problem of plastic pollution in Earth's oceans.

    More than 315 billion pounds of plastic litter the world's oceans today. Most of the plastic is garbage from towns and cities, as well as trash that people leave on beaches, rainwater, winds, and high tides bring the trash into the ocean or into rivers that lead to the ocean. Once it is under the waves, the plastic begins to break up into smaller and smaller pieces. It often collects in spots called garbage patches, which spread over large areas of the ocean.

    Thousands of marine animals--including whales, sea turtles, and fish--die each year from eating or getting stuck in plastic bags and other items. Plastic pieces can also injure coral and kill sea grass.

    Washed Ashore and other organizations are working to stop that from happening. Since 2010, Washed Ashore volunteers have collected 38,000 pounds of plastic trash from more than 3000 miles of beaches. They helped Pozzi create more than 60 sculptures of marine creatures that were harmed by plastic pollution.

    The artworks on display at the National Zoo include a 20-foot-long coral reef, a 12-foot-long shark, and a 16-foot-long parrot fish. Each one is made from hundreds of pieces of trash like water bottles and sunglasses.

    “These sculptures are a powerful reminder of our personal role and global responsibility in preserving biodiversity(生物多样性) on land and in the sea,” says Dennis Kelly, director of the National Zoo.

    Lawns（草坪）are some of the most common things in the world until you really start thinking about them. That's when you realize that they make no sense. Why do people keep these uninteresting, pointless little plants outside their homes? They're not beautiful like flowers, they don't provide food and you have to take care of them constantly.

    Israeli bestselling author Yuval Noah Harari thought these deeds were weird too. He looked into their history and ended up with an interesting story.

    No one considered putting patches of grass outside their homes in ancient times. That changed in the Middle Ages, when French and English kings and nobles started putting patches of grass at their castle entrances.

    “Well-kept lawns demand land and a lot of work,” wrote Harari in his book. “In exchange, they produce nothing of value.” Peasants could never afford to waste their time or land on lawns, so these lawns were a perfect status symbol（身份的象征）for nobility（高贵）.

    When the Industrial Revolution began in the 18th and 19th centuries, the middle classes started being able to afford their own suburban（郊区的）houses. And guess what became the suburban status symbol? A perfectly kept lawn.

    The popularity of lawns continued to grow, taking over public event spaces and sports. In the past, people played sports on all kinds of surfaces—dirt, ice, sand. But in the last couple centuries, they made the switch to green grass.

    “Grass is nowadays the most widespread crop in the USA after corn and wheat,” Harari continued. Lawns spread beyond Europe and the U.S, and they're now status symbols around the world.

    Suburban people may not realize it, but they care for lawns just because centuries ago, French and English kings wanted to show off by intentionally planting something useless. It's strange that people should continue to spend so much time and money on what's really a leftover（遗留物）from the Middle Ages. When you plan your house, you can shake off（摆脱）the cultural leftover and imagine for yourself a rock garden or some other new creation.

    After disappearing for over 19 years, measles (麻疹) is making a comeback in America. Since January 2019, the disease has infected more than 700 people, mostly small children, and the number seems to be increasing daily.

    Measles is an infectious disease that typically begins with a high fever, cough, runny nose, and red, watery eyes. Many people also lose their appetites and feel sleepy. About three to four days after the symptoms start, the person breaks out into a rash (皮疹) that begins on the face at the hairline and then spreads to the neck and the rest of the body.

    In healthy people, the recovery, which takes between two to three weeks, starts soon after the rash begins. However, for about 40 percent of patients ­ mainly kids under the age of five or older adults ­ the disease often leads to pneumonia (肺炎), which, if left untreated, could result in death.

    The recent outbreak is thought to have been caused by travelers picking up the virus in a country where the disease is still existing and exposing it to an unvaccinated (未接种的) community in the US. In New York, it was carried back by someone who had recently visited Israel, which is currently undergoing a significant measles, while in Washington, "patient zero" was infected by a type that is currently circulating in Europe.

    To limit the spread of the disease before it gets out of hand, US health officials are attempting to educate communities with high rates of unvaccinated children. They are also urging adults to consult with their physicians and get injected if considered necessary by the doctor.

    Hopefully, health officials worldwide will be able to convince parents that vaccinating their children will protect, not harm, them.

    When the tornado(龙卷风) passed, Lewis returned to her house after that awful night, and the Bible was the first thing she looked for. She had bought it 35 years earlier, at the start of her marriage. Like many folks, she'd used it to preserve the family's history: decades-old photos, newspaper obituaries(讣告) of loved ones, a handkerchief from her great-grandmother, even a piece of a scarf her uncle had brought back from the Korean War.

    The Bible was not where she'd last seen it, on top of an antique dresser in her bedroom. The only thing left was the solid pieces of marble that had been on the top of the furniture. After an hour of searching, one of the volunteers ran up to her and found the Bible while clearing through ruins. She had tears streaming down her cheeks. It had flown about ten feet from the dresser. Surprisingly, while many books had been destroyed beyond recognition, the Bible was still intact, even though it had sat in the rain for days. "It was a miracle," says Lewis.

    A few of the Bible's treasures did go missing. Yet ever so slowly, they, too, began reappearing in Lewis's life. Days after the Bible was found, volunteers discovered one of the newspaper obituaries outside the home. Two weeks later, a neighbor found another newspaper clipping(剪辑) by her house. "It was a shock," says Lewis.

    Now the Bible already has its well-deserved place of honor, on the dresser. She knows that while every good book tells stories of disastrous weather and unlikely survival, this one actually lived it.
