Question

【題目】根據(jù)短文內(nèi)容，從短文后的選項中選出能入空白處的最佳選項。選項中有兩項為多余選項。

Did you know that if you need an alarm clock to wake up in the morning, you’re probably sleep-deprived （缺失）? __【1】_______ . On average, American teens get two hours less than the average 9.2 hours of sleep they need each night to function at their best.

There are many reasons why teens don’t get enough sleep. ____【2】______ . When your parents were young, they might have read a book or watched television before trying to go to sleep. But today’s teens are likely to be surfing the Internet, texting, emailing, or playing video games right before bed. ___【3】_____ . And using them right before bed can result in difficulty getting to sleep. According to a survey by the National Sleep Foundation, teens with four or more electronic equipment in their rooms are much more likely than their peers to get an insufficient amount of sleep at night, and are almost twice as likely to fall asleep in school and while doing homework.

___【4】______ . In the National Sleep Foundation survey, three-quarters of the teens took at least one drink with caffeine every day, and nearly one-third consumed two or more every day. With all the trendy “high-energy” drinks and coffees out there right now, it’s easy to get a caffeine overload and that’s not good for sleep.

So what can you do if you’re in lack of sleep? “The good news is that you only have to make up about a third of what you have lost, to function and feel better,” says Dr. Mahowald at a sleep disorders center. ____【5】______ . But sleeping until noon on the weekend can cause problems — you’ll likely be wide-eyed until late those nights. Instead, try keeping a reasonable, regular sleeping and waking schedule.

A. One of them is a relatively new development.

B．Those extra two hours of sleep on Saturday and Sunday mornings can really help.

C．Most teens don’t get enough sleep.

D．Many teens also drink too much caffeine to sleep well.

試題分析：文章講述的是青少年需要充足的睡眠，現(xiàn)在有很多原因會導致青少年晚睡熬夜，如上網(wǎng)，打游戲或者喝咖啡等。文章建議青少年保持一個合理的，定期的睡眠和醒來的時間表。

【1】C 考查對上下文的理解和推理判斷能力。根據(jù)下一句：On average, American teens get two hours less than the average 9.2 hours of sleep they need each night to function at their best.（平均來說，美國青少年比他們需要的以達到最佳狀態(tài)的平均9.2個小時的睡眠時間少兩個小時。）可知，此處的內(nèi)容是講現(xiàn)在的青少年睡覺睡的不夠。故選C。

【2】A 考查對上下文的理解和推理判斷能力。根據(jù)上一句：有很多原因導致青少年沒有得到足夠的睡眠。根據(jù)下面內(nèi)容講“當你的父母還年輕的時候，他們可能讀書或看電視，之后去睡覺。”以及“但是，今天的青少年可能會上網(wǎng)，發(fā)短信，發(fā)郵件，或者打游戲睡覺前。”可知，此處的內(nèi)容是其中原因之一，是一個相對的新的發(fā)展的時代。即與父母的年代不同。故選A。

【3】E 考查對上下文的理解和推理判斷能力。根據(jù)上一句：但是，今天的青少年可能會上網(wǎng)，發(fā)短信，發(fā)郵件，或者打游戲睡覺前�？芍�此處的內(nèi)容是電子設備比看書看電視更令人興奮。故選E。

【4】D 考查對上下文的理解和推理判斷能力。根據(jù)下一句：在全國睡眠基金會的調(diào)查中，四分之三的青少年每天至少喝一杯咖啡，每天幾乎有三分之一的人每天兩次或更多�？芍�此處的內(nèi)容是許多青少年也喝太多的咖啡因所以睡不好覺。故選D。

【5】B 考查對上下文的理解和推理判斷能力。根據(jù)上一句：好消息是，你只需要彌補你失去的三分之一，你的狀態(tài)和感覺會更好�？芍�此處的內(nèi)容是那些在星期六和星期日的早晨額外的睡眠時間真的有幫助。故選B。
