It was one of those terribly hot days in Baltimore. Needless to say, it was too hot to do anything outside. But it was also scorching in our apartment. This was 1962, and I would not live in a place with an air conditioner for another ten years. So my brother and I decided to leave the apartment to find someplace indoors. He suggested we could see a movie. It was a brilliant plan.

    Movie theaters were one of the few places you could sit all day and—most important —sit in air conditioning. In those days, you could buy one ticket and sit through two movies. Then, the theater would show the same two movies again. If you wanted to, you could sit through them twice. Most people did not do that, but the manager at our theater. Mr. Bellow did not mind if you did.

    That particular day, my brother and I sat through both movies twice, trying to escape the heat. We bought three bags of popcorn and three sodas each. Then, we sat and watched The Music Man followed by The Man Who Shot Liberty Valance. We'd already seen the second movie once before. It had been at the theater since January, because Mr. Bellow loved anything with John Wayne in it.

    We left the theater around 8, just before the evening shows began. But we returned the next day and saw the same two movies again, twice more. And we did it the next day too. Finally, on the fourth day, the heat wave broke.

    Still, to this day I can sing half the songs in The Music Man and recite half of John Wayne and Jimmy Stewart's dialogue from The Man Who Shot Liberty Valance! Those memories are some of the few I have of the heat wave of 1962. They're really memories of the screen, not memories of my life.

    At schools across the United States, students often sit down to cafeteria lunches made from processed foods that are high in fat, sodium, and sugar. But kids at Public School(P. S. )216 in Brooklyn have a different dining experience. Principal Donna Neglia reports that her students love eating fresh fruits and vegetables.

    P. S. 216 participated in the Edible Schoolyard Project, a nonprofit program founded by Chef Alice Waters in 1995. The program that Waters created helps public schools across the country start on-site gardens and weave principles of healthy eating into the curriculum. Students grow and maintain crops, harvesting the fruits and vegetables for cafeteria meals.

    Waters expressed her passion for the principles of the farm-to-table movement. She advised schools to connect with the farmers in their area and change their buying practices when planning meals for students.

    Waters has long been inspiring people to care about where their food comes from. In 1993, she put forward the idea of a White House vegetable garden. It was not until 2009 that Michelle Obama started the garden in the backyard of the White House. She and members of the kitchen staff spent hours tending to the garden, often with help from local school children.

    “That gave people a sense that she cared about children and cared about where our food comes from,” Waters said, praising the former First Lady's concern for young people's health. “We are just building this movement, and it is very exciting. ”

    “Through the Edible Schoolyard Project, students also learn about the benefits of healthy eating in the classroom.” Neglia said. “P. S. 216 is teaching kids about careers in the food industry—such as farming and agriculture, nutrition, food safety, and the restaurant business.”

    Similar classes are taking place around the country. So far, the Edible Schoolyard Project has reached more than 1 million students in more than 367 schools. “I'm thinking about the future of the planet,” Waters said. “I'm doing this for our generation.”

    Their beautiful call suggests the arrival of spring, but the routes taken by cuckoos(杜鹃) during their annual migration(迁徙) have remained a mystery. Now, though, scientists from the British Trust for Omithology(BTO) have revealed the details of their remarkable 10,000-mile journey, with the help of tracking devices.

    Five male birds were caught in Norfolk last May and fitted with satellite-tagged "backpacks" before being released. The scientists then monitored their progress over 12 months as they flew to Africa in the autumn, and returned in the spring.

    The project was carried out to discover why every year fewer of the birds return to Britain. Between 1995 and 2010，the population of cuckoos spending summer here fell by almost half, and the number is continuing to decline. Previously, the lack of information about the cuckoos' long migration has hampered the understanding of how to help conserve the birds.

    Earlier this year, it was reported that cuckoos arrived in the UK much earlier than normal. Their call was recorded by ornithologists(鸟类专家) as early as February, a month ahead of their usual arrival.

    Like all migrating animals, cuckoos respond to the changing seasons. They depend on lush plants to provide the fruit and food for insects that they feed on. This reliance on seasonal patterns means that a changing climate could make an already challenging journey impossible for them.

    Professor Martin's report says that children who attend a number of schools, because their parents have to move around the country, probably make slow progress in their studies. There are also signs, says Professor Martin, that an unusually large number of such children are mentally affected.

    The professor says, "It's true, my personal feeling is that children should stay in one school. Our feelings are based on research and not on any personal feeling that I or many assistants may have on the subject."

    Captain Thomas James, an army lecturer for the past 20 years and himself a father of two, said, "I've never heard such rubbish. Taking me for example, no harm is done to the education of my children who change school regularly—if they keep to the same system, as in our Army school. In my experience—and I've known quite a few of them—Army children are as well-adjusted (适应) as any others, if not better. What the professor doesn't appear to appreciate is the fact that in such situations children will adapt (适应) much better than grown-ups."

    When this was put to Professor Martin, he said that at no time has his team suggested that all such children were backward or mentally affected in some way, but simply that in their experience there was a clear tendency (倾向).

    "Our findings show that while the very bright child can deal with regular changes without harming his or her general progress in studies, the majority (大多数) of children suffer from constantly (不断地) having to enter a new learning situation."

    Demand for the Chinese tech company's devices(设备) is red hot even though the country's overall market for smartphones is getting smaller Huawei's China sales rocketed more than 20% in the final quarter of 2018, and experts say that's partly due to the US government's global campaign against the company.

    “The latest tension between the US and China raised the patriotism(爱国主义) in Chinese consumers, said Jusy Hong, an analyst at research firm IHS Markit.

    He pointed out that some Chinese companies encouraged employees to buy Huawei phones late last year. The moves were a gesture of support after the firm's chief financial officer was arrested in Canada in early December at the request of the United States.

    Huawei's booming sales show how major parts of its business continue to increase even as the United States tries to persuade other countries to shut Huawei products out of 5G wireless networks and pursues(追究) criminal charges against it. The company expects to overtake Samsung as the world's biggest smartphone maker by next year.

    Huawei sold 30 million phones in China in the last three months of 2018, nearly three times as many as Apple(AAPL), according to data published this week by research firms Canalys and IDC. Apple's sales plunged almost 20%.

    Huawei's success in China, the world's largest smartphone market, is more than about geopolitics(地缘政治). Chinese consumers love its flagship, high -end- phones because they have great cameras, cutting edge technology and cost less than the latest iPhones, according to analysts. And by offering a selection of cheaper phones, Huawei is able to target a bigger market.

    It also benefited from the troubles this year at ZTE (ZTCOF), a rival Chinese smartphone and telecommunications equipment maker. ZTE was banned by the US government from buying vital American parts for months last year.

A British woman who once weighed some 322 pounds said breaking a roller coaster seat during an amusement park outing was her motivation for working toward a healthier weight.

Four years ago, Danielle Wright, 27, went to the Alton Towers theme park in Staffordshire, England, with her sister. She wanted to avoid roller coasters, fearing that she was too heavy for them. But she was convinced to give it a try and boarded one of the rides.

"Fitting in the seat was bad enough, but when it came to pulling down the safety bar, my stomach stopped it from working," she recalled. "One of the employees came over and had to put his foot against the ride and push the bar hard to make it click into place."

She was worried throughout the ride that “the bar was going to pop open and I was going to be thrown off the tracks". When the ride ended, the bar sprang up and made a huge noise. Shortly after, she heard an announcement over the loudspeaker saying the ride was temporarily closed due to a broken seat.

Though it was embarrassing, the incident presented a silver lining. "It's what I needed to motivate me to lose pounds," Danielle said. She totally changed her diet, cutting back on carbohydrate and replacing food like chocolate with healthier choices such as apples and yogurt. Meanwhile, she also began participating in workout classes.

In November 2016, Danielle found out she was pregnant. But as tempted as she was, she didn't allow herself to eat unhealthy food while pregnant and stuck to her new diet.

Now Danielle weighs some 140 pounds. "Being able to run and play with my little boy is, he best part of it all. I couldn't have asked for a better reward," she said.
