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.

Bad news travels fast--when you watch the evening news or read the morning papers, it seems that things that get the most coverage are all tragedies like wars, earthquakes, floods, fires and murders.

This is the classic rule for mass media. “They want your eyeballs and don’t care how you’re feeling,” Jonah Berger, a psychologist at University of Pennsylvania told The New York Times.

But with social media getting increasingly popular, information is now being spread in different ways, and researchers are discovering new rules--good news can actually spread faster and farther than disasters and other sad stories.

Berger and his colleague Katherine Milkman looked at thousands of articles on The New York Times’ website and analyzed the “most e-mailed” list for six months.

One of his findings was that articles in the science section were much more likely to make the list. Those stories aroused feelings of awe (敬畏) and made the readers want to share this positive emotion with others.

Besides science stories, readers were also found to be likely to share articles that were exciting or funny. “The more positive an article was, the more likely it was to be shared,” Berger wrote in his new book. “For example, stories about newcomers falling in love with New York City,” he writes, “tended to be shared more than the death of a popular zookeeper.”

But does all this good news actually make the audience feel better? Not necessarily.

According to a study by researchers at Harvard University, people tend to say more positive things about themselves when they’re talking to a bigger audience, rather than just one person, which helps explain all the perfect vacations that keep showing up on microblogs. This, researchers found, makes people think that life is unfair and that they’re less happy than their friends.

But no worries. There’s a quick and easy way to relieve the depression you get from viewing other people’s seemingly perfect lives--turn on the television and watch the news. There is always someone doing worse than you are.

1.Bad news covers most papers because　　　　 .

A. the public care for reading tragedies

B. the public intend to express sympathy for victims

C. mass media want to attract the public’s attention

D. mass media appeal to the public to help victims

2.Which of the following might be e-mailed most according to Berger?

A. The perfect vacation of your friend

B. The story of a determined inventor

C. The death of a popular zookeeper

D. The flood hitting a small town

3.We can infer from the passage that 　　　　 .

A. bad news always makes people sad

B. people prefer to share bad news with a bigger audience

C. people can relieve the depression by reading good news

D. good news sometimes has negative influence

4.What would be the best title for the passage?

A. Good News Spreads Fast

B. Bad News Travels Fast

C. The Effect of Bad News

D. The Power of Good News

I didn't just read a book in print，on an e-reader or even on a mobile phone．Instead，I read a book on dozens of devices．I was not trying to set a Guinness World Record．I wanted to answer a question I often hear： 1. ? So I set out to try them all，reading a chapter on each：the Amazon Kindle，the first and second generation Apple iPads and mobile phones．To be fair，I also read a chapter in that old-fashioned；form—a print book．

The book I chose was The Alienist．For the first chapter，I turned to an Amazon Kindle．2. ．The kinder is light．Its six-inch screen is the perfect size for reading，and reading on its black-and-white-E-Ink display doesn’t harm your eyes． 3. ，and on average you charge the device only once a month．My only complaint with the Kindle design was the placement of the keyboard at the bottom of the device．

Despite the small screen on a mobile phone，I found reading on one to be simpie and satisfactory．4. ，but all of the phones on which I read chapters felt somewhat similar．

If I had wanted to，I could have bought my book through dozens of e-book apps in the Apple App Store．Most are free and offer access to thousands of free e-books or paid versions．Both iPads l&2 offer an immersive(身临其境的)reading experience．I found myself jumping back and forth between my book and the web，looking up old facts and pictures of New York City．5. ．

For the last chapters of the book，I read the print one，which is still my favourite choice．

Since we are comparing devices So I guess I need to choose one．In the end it might come down to Kindle．But if money is tight，go for print．My used print book cost only $4 from Amazon．

A．Battery life is outstanding

B．Which e-reader is the best for reading books

C．Shopping on Amazon for the Kindle is simple

D．Should students make use of the devices to read

E．No wonder a lot of readers also speak highly of it
