Question

【題目】World Sleep Day is on March 21st. Last year’s theme was “Healthy sleep, away from the slow disease”. Its aim is to celebrate the benefits (好處) of good and healthy sleep.

Sleep is like food for the brain. Enough sleep helps the body and brain grow and develop. According to the National Sleep Foundation in the US, adults need seven to nine hours of sleep every night. For students aged 10 to 17, a healthy amount is about eight to nine hours per night.

But many students don’t get enough sleep because of early school start times and heavy homework. About 80 percent of middle school students don’t get enough sleep, the China Youth and Children Research Center reported. For some students, they want to sleep early, but they keep worrying about their schoolwork and can’t fall asleep quickly. For others, they may even have insomnia which might keep them awake all night.

These sleeping problems greatly affect people’s lives. Experts have shown that lack of sleep for teenagers leads to poor grades. Students without enough sleep cannot pay attention in class or do well in sports. Also, lack of sleep may make them depressed.

Luckily, with good sleep habits, it is easier to fall asleep. Some of these good habits include avoiding drinks that make people excited late in the day, going to sleep at the same time each night, and sleeping in a comfortable place that is dark, quiet, and neither too warm nor too cold.

【解析】文章大意：三月二十一日是世界睡眠日。去年的主題是“健康睡眠，遠(yuǎn)離慢性疾病”。睡眠就像大腦的食物，充足的睡眠有助于身體和大腦的生長(zhǎng)發(fā)育。根據(jù)調(diào)查成年人每晚需要7到9個(gè)小時(shí)的睡眠時(shí)間。對(duì)于10到17歲的學(xué)生來說，健康的睡眠時(shí)間是每晚8到9個(gè)小時(shí)。

但許多學(xué)生因?yàn)樯蠈W(xué)時(shí)間早和作業(yè)繁重而睡眠不足。這些睡眠問題極大地影響著人們的生活。專家指出，青少年睡眠不足會(huì)導(dǎo)致成績(jī)不好，此外，缺乏睡眠也會(huì)使他們沮喪。有良好的睡眠習(xí)慣，更容易入睡。

【1】細(xì)節(jié)理解題。根據(jù)第二段的For studentsaged 10 to 17，a healthy amountis about eight to nine hours per night．可知，對(duì)于10至17歲的學(xué)生，健康的睡眠時(shí)間大約是每晚八到九個(gè)小時(shí)，故選B。

【2】細(xì)節(jié)理解題。根據(jù)第四段的Students withoutenough sleep cannot pay attention in class or do well in sports．Also，the lack ofsleep may make them depressed（沮喪的）．可知，沒有足夠睡眠的學(xué)生在課堂上不能集中注意力，也不能在運(yùn)動(dòng)中表現(xiàn)良好，而且，睡眠不足可能使他們沮喪；所以睡眠不足的青少年可能會(huì)感到沮喪，故選C。

【3】細(xì)節(jié)理解題。根據(jù)第三段中But many students don’t get enough sleep because of early school start times and heavy homework.以及For others, they may even haveinsomniawhich might keep them awake all night.可知，A選項(xiàng)他們上課時(shí)注意力不集中不是學(xué)生睡眠不足的原因，故選A。

【4】細(xì)節(jié)理解題。根據(jù)最后一段的Some of thesegood habits include avoiding drinks that make people excited late in the day，going to sleepat the same time each night，and sleeping in a comfortable place that is dark，quiet，and neither toowarm nor too cold．可知，這些良好的習(xí)慣包括：避免讓人興奮的飲料，在每晚同一時(shí)間睡覺，睡在一個(gè)黑暗、安靜、既不太熱也不太冷的舒適的地方；故選C。

【5】詞義猜測(cè)題。根據(jù)后面的定語從句which might keepthem awake all night可知，能讓他們保持整夜清醒的應(yīng)是"失眠癥"，故選D。
