题文

Tho who spend more pre-bedtime hours using the Internet or watching television are more likely to report insufficient sleep, even though they sleep almost as long as people spending fewer pre-bedtime hours in front of a computer or television screen, survey findings show. “While many people u electronic media, say, the Internet, it should be noted that the longer media u before sleep can trigger (lf-perceived) insufficient sleep,” lead rearcher Dr Nakamori Suganuma, of Osaka University, Japan, told the reporter. He and colleagues obtained data on lf-perceived sleep problems and the u of electronic media prior to bedtime from 5,875 altogether Japane respondents in two parate Internet-bad surveys. Their findings are published in Sleep and Biological Rhythms.Nearly half of the respondents associated their problem with electronic media u before bedtime. Longer electronic media urs were also more likely to report insufficient sleep. “Overall, 29% of light urs (less than 1.5 hours) listed electronic media u as a possible cau of their insufficient sleep. By comparison, 40% of medium urs (1.5 to 3 hours) and 54% of heavy urs (more than 3 hours) said the same. However, longer Internet and television u before bedtime did not correlate with less actual sleep.While heavy urs averaged about 3 more hours in front of computer or television screens than light urs, the heavy urs averaged only about 12 minutes less pre-workday sleep time than light urs.Notably, Suganuma said, "Internet u affected lf-perceived insufficient sleep more than TV watching not only in younger Internet urs but also in middle-aged or aged Internet urs."Up to 38% of the respondents listed accessing the Internet far into the night as a possible cau for their sleep disturbance, while about 25% said watching television far into the night caud it.The findings suggest that while heavy computer and television u before bedtime has a small effect on sleep duration, it may have a more significant effect on "sleep demand and sleep quality," Suganuma notes.小题1: Heavy computer and television ur before bed time are more likely to be______ than light ones.A．energeticB．happyC．sleepyD．clever小题2:Which of the following statements is true according to the passage?A．Heavy computer and television ur before bed time have less sleeping time than light ones.B．Heavy computer and television ur before bed time have wor sleep than light ones.C．Tho suffering insufficient sleep spend less time in using internet than in watching TV.D．Spend less time in watching TV or surfing the internet, and you will have a better sleep.小题3:The passage ems to suggest that people ______.A．be far away from media.

调查显示，睡前长时间上网或看电视的人称自己睡眠不足的几率更大，即使他们的睡眠时间与在睡前上网或看电视时间较短的人一样多。小题1:细节题：从第一段的句子：Tho who spend more pre-bedtime hours using the Internet or watching television are more likely to report insufficient sleep, even though they sleep almost as long as people spending fewer pre-bedtime hours in front of a computer or television screen,可知睡觉前长时间用电脑，看电视的人会比时间短的人睡眠不足，所以会觉得困，选C小题2:细节题：从第四段的句子：Nearly half of the respondents associated their problem with electronic media u before bedtime. Longer electronic media urs were also more likely to report insufficient sleep.可知睡觉前长时间使用电脑，电视的人睡眠很差，选B小题3:推理题：从最后一段的句子：The findings suggest that while heavy computer and television u before bedtime has a small effect on sleep duration, it may have a more significant effect on "sleep demand and sleep quality,"可知睡觉前长时间使用电脑电视会影响睡眠质量，所以作者 是想建议读者减少熬夜上网和看电视。选C小题4:猜词题：从最后一段的句子：The findings suggest that while heavy computer and television u before bedtime has a small effect on sleep duration,可知睡觉前长时间使用电脑电视和实际的睡眠少没什么关系，选A
