Sleep is essential for a person’s wellbeing. Researchers have found that sleep loss increases a person’s risk of developing serious medical conditions. Now, a new study has found that getting enough sleep is also the key to improving academic performance.
Jeffrey Grossman, who led the research, was not trying to find the correlation (相关性) between sleep and grades when he handed out Fitbits to the students in his class. Instead, the professor hoped the popular wrist-worn electronic device (装置), which tracks a person’s activity 24/7, would show a connection between physical exercise and academic achievement.
As part of the research, a quarter of the participants chose a fitness class specially created for the study. After the school term ended, the researchers carefully analysed the data. Much to Grossman’s surprise, they found no measurable difference in test performance between the group that had been physically active and the group that had not.
However, the study presented a surprising viewpoint in the journal Science of Learning. Going through the large amount of data, Grossman noticed an interesting trend (走向) from the participants sleep patterns. There was a straight-line relationship between the average amount of sleep and his/her grade on the exams.
Besides, it was not enough for students to just head to bed early the night before a test. Grossman says: “We’ve heard the phrase ‘Get a good night’s sleep, you’ve got a big day tomorrow.’ It turns out this does not relate at all to test performance. Instead, it’s the sleep you get during the days when learning is happening that matters most.”
The time students went to bed each night was similarly important. Those who went to bed in the early hours of the morning performed poorly, even if the total sleep time was the same as a higher-performing student.
The research does not prove that sleep is the only component that helps improve academic performance. However, Grossman says the results are a strong indication that sleep really matters. Who knew getting A’s just required some extra ZZZ’s?

The band Coldplay has released (发行) a new album called “Everyday Life”. But the group has announced it won’t go on tour until it can figure out how to tour without making the climate worse.
Normally when bands have a new album, they go on tour to promote (推销) the album. They may fly from country to country and drive across countries in buses, performing in concert after concert.
Touring is an important way singers and musicians earn money. But tours are very hard on the environment. Flying is one of the biggest sources of greenhouse gases. During their last tour, the band flew to five different continents and played 122 shows. They traveled with 109 supporting workers, 32 trucks, and 9 bus drivers. Think about the pollution from Coldplay’s flights as well as the trucks, buses and huge amounts of electricity required to power the shows!
It’s hard to keep track of the pollution a band creates while touring, but most of the environmental cost comes from the fans. During their last tour, Coldplay entertained 5.4 million fans, all of whom had to travel to the concerts and bought “merchandise” like T-shirts, CDs and posters. Some bought food and drinks at the concerts, creating tons of plastic waste.
Instead of touring to promote the new album, Coldplay recorded two videos of the band playing their new songs live in Jordan and has put the videos of their performances up for free viewing on YouTube.
Coldplay, one of whose dreams is to have a show with no single-use plastic and have it largely sun-powered, says it won’t tour again until its members work out how to make their tours help instead of hurt. The decision will cost the band a lot of money in the short run, but it could pay off big for the planet.
1.Why is Coldplay’s last tour mentioned twice by the author?
A.To stress the necessity of the tour.
B.To describe Coldplay’s great popularity.
C.To introduce Coldplay’s basic information.
D.To show huge environmental costs of the tour.
2.How did Coldplay promote the new album?
A.By making a tour in Jordan.
B.By distributing free CDs to fans.
C.By posting their performances online.
D.By performing their new songs live on TV.
3.Which of the following best describes Coldplay’s decision to quit tours?
A.Thoughtless. B.Meaningful.
C.Temporary. D.Doubtful.

Why are some people successful and others aren’t? What’s the secret of success? 1.
Many of Gladwell’s ideas appear in his social psychology bestseller Outliers.2. Gladwell thinks that this is just an excuse for not trying… and if you really want to be good at something, you have to work at it. “Practice isn’t the thing you do once you’re good,” Gladwell writes. “It’s the thing you do that makes you good.”
Central to the book is the “10,000-hour rule”. It means that if you want to be among the best in the world, you need to practise something for 10,000 hours. 3. For example, the Beatles played live in Hamburg more than 1,200 times between 1960 and 1964, which is more than 10,000 hours of playing time. And when Microsoft chairman Bill Gates was 13, he was given access to a high school computer (one of the few available in the country), allowing him to practise computer programming for more than (Yes, you guessed it!) 10, 000 hours.
4. Take the example of Christopher Langan, who’s mentioned in the book. He’s got an IQ of between 195 and 210 (Albert Einstein’s IQ was estimated to have been between 160 and 180). As a boy at school, Langan was able to take an exam in a foreign language he’d never studied and pass it after just skim-reading a text book for three minutes. However, Langan never graduated from university and worked in labour-intensive jobs his whole life. This proves that intelligence alone will not lead to success—you need hard work, support, finance and opportunities. Gladwell adds, “No one — not rock stars, not professional athletes, not software billionaires, and not even geniuses — ever makes it alone.”
5. Even after you’ve put in your 10,000 hours of practice, you still need one other key ingredient — luck. So, you could be the most amazing guitarist in the world, but unless you’re lucky enough to play in front of a record company executive who sees a way of exploiting that talent, you aren’t going to be seeing your name in lights.
A.It isn’t just a question of time and support.
B.Author Malcolm Gladwell thinks he knows.
C.That’s equal to three hours a day for 10 years.
D.Of course, many people argue that you can create your own “luck”.
E.The popular view is that some of us are born talented and others aren’t.
F.The interesting thing is that success has nothing to do with intelligence.
G.Someone who’s willing to practise something for 10,000 hours is probably active.
