【题目】More and more people are taking their iPads to bed with them to surf the web, check facebook or send e-mails before switching off the light. But researchers are warning that the blue light their screens give off can stop users getting a good night’s sleep. That is because this type of light is similar to daylight, convincing the brain that it is still daytime. Blue light prevents the production of a brain chemical called melatonin, which helps us fall asleep. By contrast, light which is more orange or red does not prevent melatonin production, perhaps because our brains recognize it as a cue that the day ends.

Scientists have known for years that staring at screens late in the evening can affect sleep ---- they are television screens, computer screens or mobile phone screens. However, because mobiles and iPads are by nature portable ---- not to say addictive ---- more people are taking them into the bedroom. Users also tend to hold them much closer to their eyes than a computer or television screen.

Researchers are warning that looking at iPad displays for more than two hours leads to lower natural melatonin levels as the devices give off blue light. They say, “Turning off the devices at night is the final solution. But if you have to use these devices at night, dim the display to cut down irritation of the eyes and limit the time you spend on them before bed.”

They wrote in the journal Applied Ergonomics(应用人类工程学) that iPad makers should adjust the spectral power distribution(光谱功率分布) of the devices so that they affect the sleep patterns of users less.

It is not just a good night’s sleep that could be harmed by too much late night screen time. Researchers know that long-term harm to sleep patterns can lead to an increased risk of obesity and even cancers.

What’s the main idea of the passage?

A. Scientists are warning that blue light is bad for our health.

B. People should limit the use of electronic devices

C. Using iPads before bed can cause a poor night’s sleep.

D. Looking at screens of iPads increase chances of sleeplessness.

【题目】When there are some strangers in front of us, which of them will we trust?

According to a new study in the online PLOS One, people make their decisions to trust others largely based on their faces．Your appearance can do a lot for you, especially if you are in the financial industry．The more trustworthy you look, the more likely people will buy what you’re selling．

Researchers from Britain’s University of Warwick Business School, University College London, and Dartmouth College, US, did a number of experiments．

The research team used computer software to make 40 faces, from the least to the most trustworthy-looking．

The study said that the difference between a trustworthy face and one that isn’t as trustworthy comes from features that look slightly angry or slightly happy, even when the face is at rest．However, a slightly happy face is more likely to be trusted．

Researchers gave participants some money and asked them which face they trusted to invest the money for them．Then researchers gave some good and bad information about the people with these faces, and asked the participants again whom they trusted．

The results showed that even if they got different information, the participants didn’t change their choices．They were still more likely to invest their money with the more trustworthy-looking faces．

Chris Olivola, one of the study’s authors, said in the University of Warwick’s press release: “It seems we are still willing to go with our own instincts about whether we think someone looks like we can trust them．The temptation to judge strangers by their faces is hard to resist．”

Which of the following can be a proper title for this passage?

A．What kind of face do you trust?

B．Who did the experiments?

C．Why do you trust him or her?

D．Why did they do the experiments?
