Some people surveyed tasted the sweet, salty and crunchy together with other tastes of food as they listen to different noises.It shows that louder noises reduced the reported sweetness or saltiness of food while incr eatasing the measure of crunchiness（松脆）.

    It may go some way to explain Why airline food is widely complained about by both the workers and paddengers.Andy Woods,a researcher,said,“It's a general opinion that plane foods aren't fantastic,but I'm sure airlines do their best,so we wondered if there were other reasons,One thought was that perhaps the background noise may have an effect.NASA gives their space explorers very strong -tassting foods,because for some reason,they can't taste food that Strongly-^again, it may have something ti do with the background noise.”

    In a study ,48 people were fed sweet foods or salty ones, while listening tonoting or noise through earphone. Meanwhile they rated(划分等级) the foods. In noisier settings,foods were rated less or sweet than they were when it was silent,but were rated crunchier.“The evidence shows that if the background noise is loud, your food, attention might be drawn to that, away from the food.” Dr. Woods said.

    “We ae still at an early stage of progressing and this is a rather small  study to really draw definitive(最完整可靠的）conclusions from,” Dr. Woods said,“but they suggest that restaurants could well their choice of food for a given environment.”

    Also in the group's findings there is the suggestion that the overall satisfaction with the food is also related to the degree to which people like what they are hearing .

    For most city people, the elevator is an unremarkable machine that inspires none of the enthusiasm or interest that Americans afford trains, jets，and even bicycles. Dr. Christopher Wilk is a member of a small group of elevator experts who consider this a misunderstanding. Without the elevator, they point out, there could be no downtown skyscrapers or tall buildings, and city life as we know it would be impossible. In that sense, they argue，the elevator's role in American history has been no less significant than that of cars. In fact, according to Wilk_? the car and the elevator have been locked in a “secret war” for over a century, with cars making it possible for people to spread horizontally (水平地)，and elevators pushing them toward life in close groups of towering vertical (垂直的)columns.

    If we tend to ignore the significance of elevators, it might be because riding in them tends to be such a brief, boring, and even awkward experience^one that can involve unexpectedly meeting people with whom we have nothing in common, and an unpleasant awareness of the fact that we're hanging from a cable in a long passage.

    In a new book, Lifted, German journalist and cultural studies professor Andreas Bernard directed all his attention to this experience, studying the origins of elevator and its relationship to humankind and finding that riding in an elevator has never been a totally comfortable experience. “After 150 years, we are still not used to it”， Bernard said. “We still have not exactly learned to cope with the mixture of closeness and displeasure.” That mixture, according to Bernard, sets the elevator ride apart from just about every other situation we find ourselves in as we go about our lives.

    Today，as the world's urban population explodes，and cities become more crowded, taller, and more crowded, America's total number of elevators—900,000 at last count, according to Elevator World magazine's “2012 Vertical Transportation Industry”一are a force that's becoming more important than ever. And for the people who really, really love them, it seems like high time that we looked seriously at just what kind of force they are.

    A Chinese team claimed victory at an international e-sports（电子竞技）championship held in Paris on Sunday.

    Royal Never Give Up beat South Korean team Dragon X 3-1 to lift the crown at the League of Legends Mid-Season Invitational 2018. It marked the first time in 1,106 days that a South Korean team had been defeated by a team from elsewhere at a major international League of Legends tournament（锦标赛）.

    League of Legends is a multiplayer online battle arena video game that was launched in 2009 and rapidly built a following among members of the competitive gaming community. The tournament in Paris featured teams from 13 countries and regions competing for cash and a place in the global rankings.

    Royal Never Give Up entered the contest fresh from their victory at the spring season of the Tencent League of Legends Pro League, the top level of China's professional League of Legends league system. Their win in Paris was largely owing to star player Jian Zihao, aka Uzi. “I've been trying to win this title for six years now,” Jian said on stage following the victory. “I can't imagine I'm standing here with this trophy. I'm super excited for this moment.” Royal Never Give Up's victory has boosted confidence in China's ability to win at major international e-sports events.

    E-sports' popularity has ballooned in recent years, with the International Olympic Committee scheduled to meet in July to further discuss the possibility of including e-sports in future Olympic Games. According to Penguin Intelligence's 2017 China Game Industry Report, released in June, the annual market value of China's e-sports sector reached 20 billion yuan ($3.13 billion) in 2016, generated by gamers' spending, copyright distribution, merchandising and e-commerce. The number of registered online gamers jumped to 220 million in 2017 from 170 million the year before.

    Mom noticed that something was wrong when I started getting so thirsty. I'd have a lot to drink before bed, which was unusual for me. One time, I opened a big container of apple juice and kept refilling my glass. Before I knew it, I'd drunk the entire container! My mom called my doctor. I then had a few blood tests, and the results were certain — I had diabetes (糖尿病), which meant that the amount of sugar in my blood was very high. That can be dangerous, so I had to learn how to control my blood-sugar level.

    My eating habits had to change in a big way. With diabetes, I can't eat a lot of sugar or carbohydrates (碳水化合物). I have to figure out exactly how much sugar I plan to eat, and then I get an injection of insulin (注射胰岛素) before the meal to help my body process the food. Also, I test my blood-sugar level often. I'm always trying to keep my blood sugar at a healthy level. The level can drop when I exercise, but that doesn't keep me out of gym class or off the basketball court — I just keep some juice boxes around to boost my blood sugar if I need to.

    It's a lot of work and not a lot of fun to keep track of everything, but I've gotten used to my new habits. I was a little scared at first because I wasn't sure how my life would change. Once I knew what I needed to do, though, it wasn't a big deal. My life is different now from what it was before, but it has become completely regular to me.

    The world's first-known nursery for baby giant manta rays(蝠鲼) has been discovered hidden away in the Gulf of Mexico, the place of 70 miles off the coast of Texas, after studying decades of giant manta ray data from the area by the scientists.

    Where the baby manta rays grow up has long troubled scientists, as they are rarely spotted in the four to five years it takes them to become adults, when they can often grow to more than 20ft wide.

In the study Mr Stewart and colleagues describe a reef (暗礁)—filled with mantas of all ages—where the sea floor runs down into deeper water. He said "We think they may be feeding on specific types of zooplankton(浮游生物) there, then migrating up toward the surface, where we saw them. They might be hanging around the banks because it could be a little safer than open water. We've seen them so rarely that we know very little about these baby manta rays. We don't know how far they move, or exactly what they feed on, or all of the habitats these access.”

    Giant manta rays are listed as species dying out by protectors, although actual population numbers of the mysterious "gentle giant" are hard to calculate. Sightings of the closely-related reef manta, however, have dropped by 90 percent in regions of southeast Asia in the past decade, according to a study.

    Fishing is considered the biggest threat to giant manta numbers, both intentional and accidental. Their gill plates(腮下肉)- the parts through which they filter(过滤) their food from seawater-are sold in China for medical purposes, while they often end up as something caught by mistake due to their huge wings.

    When you live in total messiness—cookies in your pants draws, and some old New Yorkers or apple seeds in your bed—it's hard to know where to look for when you lose your keys. The other day, after two weeks of searching, I found my keys in the refrigerator. I can't say I was surprised. But I was surprised when I was diagnosed with ADHD(多动症), when I was a junior at Yale.

    According to a new study, 11% of school-age children have received an ADHD diagnosis, a 16% increase since 2007. And rising diagnoses mean rising treatments—drugs like Adderall are more accessible than ever. However, the consequences of misuse and abuse of these drugs are dangerous.

    Yet also harmful are the consequences of ADHD undiagnosed, an all-too-common story for women like me, who have symptoms, like disorganization and forgetfulness, which look different from those typically expressed in males.

    Dr. Ellen, author of Understanding Girls with ADHD, has found around 4 million females with ADHD are not diagnosed. "The main reason is that the diagnostic criteria were developed based on those hyperactive（过度活跃）young boys taken to clinics, making it difficult for girls to be diagnosed unless they behave like hyperactive boys." Ellen says.

    Besides, the idea that young women actually have ADHD often causes skepticism. As a top student, I didn't believe my diagnosis at first. My friends were also confused, and rather certain my doctor was misguided.

    "Often, if girls are smart or in supportive homes, symptoms are masked," Dr.Ellen says. "Girls will hide their inability to meet social expectations. They see their trouble organizing, and concentrating as character flaws(缺陷)."

    These years, I am both embarrassed and exhausted by my struggles to keep track of objects, but drug has helped it and made it more bearable.
