Most evenings, before watching late-night comedy or reading emails on his phone, Matt Nicoletti puts on a pair of orange-colored glasses that he bought for $8 on the Internet.
"My girlfriend thinks I look ridiculous in them," he said. But Mr.Nicoletti, a 30-year-old consultant in Denver, insists that the glasses, which can block certain wavelengths of light emitted by electronic screens, make it easier to sleep.
Studies have shown that such light, especially from the blue part of the spectrum (光谱),inhibits the body's production of melatonin(褪黑激素)，which helps people fall asleep. Options are growing for blocking blue light, though experts caution that few have been adequately tested for effectiveness and the best solution remains avoiding brightly lit electronics at night.
A Swiss study of 13 teenage boys, published in August in The Journal of Adolescent Health showed that when the boys wore orange-colored glasses, also known as 'blue blockers' and shown to prevent melatonin, in the evening for a week, they felt "significantly more sleepy" than when they wore clear glasses.The boys looked at their screens, as teenagers tend to do, for at least a few hours on average before going to bed, and were monitored in the lab.
Older adults may be less affected by blue light, experts say, but blue light remains a problem for most people, and an earlier study of 20 adults aged 18 to 68 found that those who wore orange-colored glasses for three hours before bed improved their sleep quality considerably relative to a control group that wore yellow-colored lenses, which blocked only ultraviolet(紫外线) light.
LEDs used in devices such as smart phones, tablets and televisions tend to emit more blue light than incandescent products（白炽产品). LEDs are also increasingly popular as room lights, but "warm white" bulbs, with less blue, tend to be a better choice than "cool white" for nighttime use. The lighting company Philips also makes a reduced-blue LED bulb, meant to be used before bedtime."In theory, anything that will decrease that blue light exposure at night will be helpful." said Christopher Colwell, a scientist at the UCLA, "I know some gainers who swear by those orange-colored glasses."
But orange glasses are not a panacea(万能药). Dr. Skene said."It isn't just getting rid of the blue and everything's fine," she said. The intensity of light, in addition to color, can affect sleep, she said, and not all brands of orange-colored glasses have undergone enough independent testing for their ability to aid sleep.
During the daytime, experts say, exposure to blue light is good. Best of all is sunlight, which contains many different wavelengths of light."That's what our brain knows," said Kenneth P.Wright Jr., director of the sleep and chronobiology(生物钟学) lab at the University of Colorado, Boulder.
A 2013 study he led, published in the journal Current Biology, showed just how different things can be without nighttime lights. After participants had camped in the mountains for a week, their bodies began to prepare for sleep about two hours earlier than normal.
Short of cutting out all evening electronics, experts say, it's advisable to use a small screen rather than a large one; dim the screen and keep it as far away from the eyes as possible; and reduce the amount of time spent reading the device.
"If you can look at the iPhone for 10 minutes rather than three hours, that makes a lot of difference," Dr.Skene said.

The triathlon(铁人三项运动) promises to be one of the most popular Olympic sports. Recently it has drawn huge crowds attracted by athletes swimming 1,500m, cycling 40km, and then running 10km, without stopping. But what makes an attractive 17-year-old give up everything for the doubtful pleasures it offers?
Melanie Sears has not yet learnt those often-repeated phrases about personal satisfaction, mental challenge and higher targets that most athletes use when asked similar questions. “You swim for 1,500m, then run out of the water and jump on your bike, still wet. Of course, then you freeze. When the 40km cycle ride is over, you have to run 10km, which is a long way when you’re feeling exhausted. But it’s great fun, and all worth it in the end,” she says.
Melanie entered her first triathlon at 14 and she won the junior section. Full of confidence, she entered the National Championships, and although she had the second fastest swim and the fastest run, she came nowhere. “I was following this man and suddenly we came to the sea. We realized then that we had gone wrong. I ended up cycling 20 kilometers too far. I cried all the way through the running.”
But she didn’t give up. “Sometimes I wish I could stop, because then the pain would be over, but I am afraid that if I let myself stop just once, I would be tempted to do it again.” Such doggedness draws admiration from Steve Trew, the sport’s director of coaching.
Melanie was top junior in this year’s European Triathlon Championships, finishing 13th.“I was almost as good as the top three in swimming and running, but much slower in cycling. That’s why I’m working very hard at it.” She is trying to talk her long-suffering parents, who will carry the ￡1,300 cost of her trip to New Zealand for this year’s world championships, into buying a ￡2,000 bike, so she can try 25km and 100km races later this year.
But there is another price to pay. “I don’t have a social life,” she says. “After two hours’ hard swimming on Friday night, I just want to go to sleep. But I phone and write to the other girls in the team.” What does she talk about? Boys? Clothes? “No, what sort of times they are achieving.”
1.How does Melanie differ from other athletes, according to the writer?
A. She worries less than they do.
B. She expresses herself differently.
C. Her family background is not like theirs.
D. Her aims are different from theirs.
2.What upset Melanie during the National Championships?
A. She was tricked by another competitor.
B. She realized she couldn’t cycle as fast as she thought.
C. She felt she had let her team-mates down.
D. She made a mistake during part of the race.
3.What does the underlined word “doggedness” in Paragraph 4 means?
A. Melanie knows her own limits.
B. Melanie likes to please her coach.
C. Melanie feels less pain than most people.
D. Melanie continues regardless of difficulties.
4.What is Melanie trying to persuade her parents to do?
A. Buy an expensive bike for her.
B. Give her half the cost of a bike.
C. Pay for her to go to New Zealand.
D. Let her compete in longer races.
5.Which of the following can be the best title for the text?
A. Melanie’s Dull Social Life
B. Melanie’s Personal Achievements
C. The Pain and Suffering Caused by the Triathlon
D. The Triathlon’s Great Attraction

Tristan da Cunha, a 38–square–mile island, is the farthest inhabited island in the world, according to the Guinness Book of Records. It is 1,510 miles southwest of its nearest, St. Helena, and I,950 miles west of Africa. Discovered by the Portuguese admiral (上将) of the same name in 1506, and settled in 1810, the island belongs to Great Britain and has a population of a few hundred.
Coming in a close second–and often wrongly mentioned as the most distant land–is Easter Island, which lies 1,260 miles east of its nearest neighbor, Pitcairn Island, and 2,300 miles west of South America.
The mountainous 64–square–mile island was settled around the 5th century, supposedly by people who were lost at sea. They had no connection with the outside world for more than a thousand years, giving them plenty of time to build more than 1,000 huge stone figures, called moai, for which the island is most famous.
On Easter Sunday, 1722, however, settlers from Holland moved in and gave the island its name. Today, 2,000 people live on the Chilean territory (智利领土). They share one street, a small airport, and a few hours of television per day.
1.It can be learned from the text that the island of Tristan da Cunha ________.
A. was named after its discoverer
B. got its name from Holland settlers
C. was named by the British government
D. got its name from the Guinness Book of Records
2.Which of the following is most famous for moai?
A. Tristan da Cuha. B. Pitcairn Island.
C. Easter Island. D. St. Helena.
3.Which country does Easter Island belong to?
A. Britain. B. Holland. C. Portugal. D. Chile.
