Research has shown that taking a break or a nap can help the brain create_________to a solution. Now a new study_________on the effect of this so-called incubation（潜伏期）by using sound cues to focus the sleeping mind on a targeted problem.

When humans sleep, parts of the brain replay certain memories, strengthening and transforming them. About a decade ago researchers developed a technique, called targeted memory reactivation（TMR）, aimed at further enhancing_________memories: when a sound becomes associated with a memory and is later played during sleep, that memory gets_________. In a study published last November in Psychological Science, scientists tested whether_________the memory of a puzzle during sleep might also improve problem-solving.

About 60 participants visited the laboratory before and after a night of_________. First, they_________spatial, verbal and conceptual puzzles, with a distinct music clip repeating in the background for each, until they had worked on six puzzles they could not solve. Overnight they wore electrodes（电极）to detect slow-wave sleep, which may be important for memory enhancement—and a device played the sounds _________to three of the six unsolved puzzles. The next day, back at the lab, the participants attempted the six puzzles again.（Each repeated the experiment with a different set of puzzles the following night.） All told, the subjects solved 32 percent of the sound-stimulated puzzles compared with 21 percent of the _________puzzles.

The researchers "very bravely went for quite complex tasks that involved a lot of complex processing, and remarkably they found these really strong effects in all of their __________." says Penny Lewis, a psychologist at Cardiff University, who was not involved in the research. "These are supercool results. Now we need to go out and try to understand them by firstly replicating（复制）them and secondly trying to __________the component processes that are actually being influenced."

Beyond providing new evidence that humans restructure memories while sleeping, the research may have __________implications. "In a futuristic world, maybe TMR could help us use sleep to work on our problems," says lead author Kristin Sanders, who was a graduate student at Northwestern University during the study. Sleep-monitoring technology is increasingly accessible—and even without devices, prospective solvers can focus on important problems before __________.

Still, sleep is not __________; people need to do their homework and load their heads with the puzzle pieces involved. "I'm not going to solve cancer with this technique," Sanders says, "because I am totally __________cancer research."

【推荐2】Chinese cuisine (烹饪) is widely known and enjoyed all around the world. Who doesn’t _________ a favorite Chinese dish? But there is one interesting _________ concerning Chinese food which is almost unheard-of in the West, and _________ ignored by the youth of the East—the ancient custom of “tonic (滋补) food”.

Tonic food is food consumed to improve one’s well-being or _________ sickness. _________, it was once the _________ for new mother to eat a sesame-oil(麻油) hotpot every day for the first month after giving _________. It was believed that this dish would _________ the muscles, reduce pain, improve circulations, stimulate sweating and _________ the body.

Some food are __________ as “hot”, such as goat meat and coriander (香菜), while others, such as Chinese cabbage and radish (小萝卜) are “cold”. One should be __________ not to eat too much “hot” or“cold”food. __________, how much “hot” or “cold” food one should eat __________ the time of the year, how the food is prepared and what it is prepared __________, and the individual’s __________.

The custom of employing tonic food for a healthier life also __________ the catering (餐饮) industry. Some Chinese herbal medicines can often be found on many a restaurant __________. Whether you need to __________ yourself to boost your energy with a large helping of chicken soup or increase your __________ power with a serving of pig’s brain soup, you may find that this ancient Chinese custom could be __________ the tonic you are looking for.

【推荐3】If you look Chinese and speak Mandarin, you can call for a ride in Vancouver via WeChat, a Chinese app. The drivers normally call back to________the order, says Daniel Merkin, who lives in the Canadian city. “Sometimes they’ll ________ on me when they realize I don’t speak Mandarin,” he says. But he keeps ________, because popular ride-hailing (网约车) services, like Uber(优步) , are not available. The Chinese service is not legal, but it is ________. Mr. Merkin hopes that his ________ will soon expand.

In July the province of British Columbia, which licenses drivers, said it would allow the big ride-hailing services ________. But British Columbia has made their entry ________ by requiring drivers to hold commercial licenses. The government has reason to be ________. In many cities where ride-hailing has __________, traffic jam has worsened and use of public transport has ________.

However, Andrew Curran, head of policy at TransLink, the city’s public-transport system, believes ride-hailing could ________ use of public transport by ferrying people from their houses to a bus or train stop. It could also improve transport for people with ________. Currently, Trans-Link hires taxis to give door-to-door rides to some disabled people. He says the commercial-license rule will   slow down the services’ growth and ________ taxi-drivers, ride-hailing’s fiercest ________.

But the commercial-license requirement could have the ________ effect. Analysts think it will ________ most drivers and reduce the number of drivers ________ to pick up passengers in distant suburbs. ________, they will gather in the center. Some of Uber’s future competitors say they are not ________. A driver, who offers rides in his Mercedes SUV to people who hire him via Wechat, thinks his customers will stay ________. He predicts ride-hailing will just slow their journeys down.
