The beginning of our sleep-shortage crisis can be traced back to the invention of the light bulb(灯泡)a century ago. From some diaries and other personal accounts in the 18th and 19th centuries, sleep scientists have come to believe that the average people used to sleep about nine hours and a half each night. " The best sleep habits were once forced on us when we had nothing to do in the evening on the farm and it was dark," says sleep specialist Roffwarg.
By the 1950s and 1960s, that sleep schedule had been decreased greatly to between seven hours and a half and eight hours. Now social and economic tendencies are cutting even deeper.
Perhaps the most cruel robber of sleep, researches say, is the complex things of the day. Whenever pressures from work, family, friends and community become greater, many people consider their sleep can be given up for them. Another thief of sleep is shift work, in which people work regularly in the evening, at night or on rotating(轮流) schedules, Researchers say the brain has difficulty varying sleep times, which means that these employees usually suffer a final loss of sleep.
The availability of round-the-clock entertainment, especially all night television, also strengthens the effect of sleep-shortage. Not long ago most TV stations had to close broadcasting at midnight or 1 a. m. to urge many viewers to retire.
Which statement is TRUE according to the last paragraph?
选项
A、The TV stations had to stop earlier to force people to go to bed.
B、Because we had other entertainments, TV stations had to dismiss some of their employees.
C、Most TV stations urged the audience to stop watching TV to go to other entertainment places.
D、Many people working in TV stations can’t sleep well because they work the whole night.
答案
A
解析
文章最后一句话:不久以前电视台被迫停止了在午夜或晚间一点钟的播出,促使观众休息。因此可以得出A项是正确答案。
