The popularity of award-show fashion has practically eclipsed the award shows themselves. For the 2017 Oscars, the Network devoted an entire broadcast day to the red carpet, starting with a morning “pre-pre-show” called “Countdown to the Red Carpet” followed by the hours-long “Live from the Red Carpet." For designers, the red carpet is one of the most visible and popular ways to promote their brands. In fact, some top designers will pay A-list actresses and musicians big bucks to wear their dress or jewelry. Other celebrities are allowed to “borrow” a designer dress, handbag or diamond-studded necklace for the night- for free of course- in order to get the designer's name in the highly clickable red carpet photo slideshows. But what happens to that very expensive dress when the red carpet is rolled up and the TV cameras move on to the next event? Is the gown stuffed into a closet never to be worn again, or does the designer take it down to the dry cleaner and try to sell it on websites? We reached out to Ariana Weisner, a Hollywood stylist, for some answers. Weisner says that 99.99 percent of the dresses loaned out for award shows go right back to the designer. According to Weisner, on rare occasions, the designer will gift the celebrity the gown. The most famous example was the green Versace dress that Jennifer Lopez wore to the 2000 Grammys. Versace gifted her the dress, because it was such an iconic moment, and the dress is still in Jennifer's closet.“The really big design houses will take back a red-carpet dress and keep it in their archives," says Weisner. “You won't see a ‘statement’ gown from the Oscars resold to the public, dry-cleaned or not. But that's not the case for lower-tier designers." Weisner cites the rise of fashion rental companies in Los Angeles and New York for this trend. Less conspicuous red-carpet dresses could very well end up in shops a few years after a big event. Sample sales are another place where you might stumble upon a dress that a celebrity wore for one big night. When a designer's warehouse becomes overstuffed with leftovers from last year's line, and sample -sized dresses that were tried on repeatedly in the store, they hold a sample sale. Sometimes you can get a dress from a sample sale that a celebrity has worn in the past. They're usually pretty cheap, too, because it's already been used.Even if you can't get the very same dress that a celebrity wore on the red carpet, you might be able to buy an exact copy. Every once in a while, says Weisner, a dress at an award show is picked up for mass production. One example is a silver dress that Kate Hudson wore to the 2016 Vanity Fair Oscars post-party. The designer sells the same dress online for $3,325.Really luxurious dresses not only grab the attention of viewers, but also thieves. At the 2015 Oscars, actress Lupita Nyong'o wore a white gown studded with 6,000 pearls worth an estimated $150,000. The gown was reported stolen from Nyong'o's hotel the day after the Oscars, but was then mysteriously “returned" by the thief. According to TMZ News, after the burglar snatched the gown, he removed two pearls and took them down to the garment district. They were fakes! The thief dumped the “worthless" dress in a bathroom back at the hotel and informed TMZ of its location.1. How would some fashion designers promote their brands in Oscar award shows?2. What happens to the red carpet dresses by less-known designers according to Weisner?3. Which of the following is closest in meaning to the word “conspicuous" in Paragraph 3?4. Why was Lupita Nyong'o's stolen gown returned by the thief?5. What is the passage mainly about?

Wearable gadget (可穿戴设备) companies claim that their bracelets and watches can improve our lives by helping us detect health problems so that we can come up with solutions. For many years, fitness gadgets have measured basic data, like footsteps or calories burned, to motivate us to stay active or shed pounds. Sleep tracking is still a new area- one that I've watched with interest, as someone who has been sleep-deprived for many years. Would it really make a difference, I wondered, to have this data? Would it help me to sleep better?I decided to test it out. I wore an Apple Watch. I also downloaded a top-rated app called AutoSleep. Ultimately, the technology did not help me sleep more. It didn't reveal anything that I didn't know. And the data did not help me answer what I should do about my particular sleep problems. In fact, I've been easily annoyed since I started these tests. This mirrored the conclusions of a recent study. Researchers noticed patients complaining about sleep data collected by apps and devices. They warmed that sleep-tracking tech could provide inaccurate data and worsen insomnia (失眠) by making people obsessed with achieving perfect sleep. They supported the idea that health apps don't necessarily make people healthier.For some practical tips on how to get more shut-eye, I sought out Raphael Vallat, a researcher at the University of California, Berkeley. His most important advice: Do not check your sleep data on a regular basis. “If you look at your data, you may think: Oh, gosh, I didn't sleep well. Should I be tired? Am I in a bad mood?" he said.To understand sleep-tracking data, I dug into how sleep works. There are three main stages: light sleep, deep sleep and REM sleep (for rapid eye movement). The deep sleep stage is beneficial for physical restoration, researchers said. REM sleep, the stage in which we dream, helps in repairing our psychological and emotional networks. On average, a person completes a sleep cycle, which includes each of the three main stages, every 90 minutes. To get a good night's sleep, you need to complete four or five cycles. That's partly because the cycles are not the same throughout the night: the early cycles have more deep sleep, whereas the later ones have more REM sleep.But our sleep-tracking tech? It generally can't accurately measure REM sleep. Sleep-tracking apps primarily look at movement and heart rate to determine when you are asleep or awake- which are generally not precise enough to measure the different sleep stages. Without a good look at REM sleep, these apps may give an incomplete picture of sleep quality. My sleep-tracking statistics said I needed more sleep, but the app stopped short of offering advice on how to solve my personal sleep problems. It's just information. Can I do anything on my own to optimize (使完善) it? Or is the information just worthless or is it making things worse? Sometimes being aware of it just makes you even more anxious. It's a vicious cycle, because if you immediately feel you didn't sleep enough, it will impact your mood.Dr. Vallat advised making the bedroom a cool environment and as dark as possible; avoiding alcohol in the evening; not checking social media right before bed. That all sounded reasonable- and there's no app needed for any of that.1.What is the function of fitness gadgets according to Paragraph 1?2.What was the reason for the writer to pay more attention to sleep tracking tech?3.Which of the following statements is true according to Paragraph 2?4.What is the problem of sleep tracking apps in measuring people's sleep?5.What do we learn from the last paragraph?
