【题目】 Do you have any online classes? It is possible to take classes at home. All you need is a computer and a headset.

However, most students don't seem to like online classes. According to a recent survey, only 33 percent of students would take such classes. Over 1,500 students from 10 cities took the survey.

Many students said it is hard to focus on studying while taking online classes. This was true for Lian Ruohan, 15, at the Affiliated High School of Peking University. “There are no classmates, no real teachers watching me. I can surf the internet or do other things if I want to. It's harder to always stay focused," she said.

【题目】 In today's world, sleep experts say that for a better night's rest, Americans should turn off their smartphones or iPads before sleeping. Such electronic products make the brain more active, and then influence people's sleep. But according to a latest survey, more than 90% of Americans usually use a computer or some other kinds of electronic products in the hour before bed.

Researchers found that man-made light from some electronic products at night might reduce the levels of the brain chemicals that help sleep. The researchers showed that sitting in the light from tablets clearly reduced the levels of the chemicals which manage our body clocks and play a great role in the sleep cycle.

In the study, the researchers let volunteers read, play games and watch movies on a tablet for different time while measuring how much light their eyes received. They found that sitting for two hours before a bright tablet at night reduced the levels of the chemicals by about 22%.

Studies of students using computers at night have got the similar results. And researchers said that might not only cause sleeplessness, but also increase the risk of obesity(肥胖症), diabetes(糖尿病) and other diseases.

To be on the safe side, the researchers advise us to use computers less before bed, or turn down our screens low.
