Question

【題目】With around 100 students scheduled to be in that 9:00 am Monday morning lecture, it is no surprise that almost 20 people actually make it to the class and only 10 of them are still awake after the first 15 minutes; it is not even a surprise that most of them are still in their pajama’s(睡衣). Obviously, students are terrible at adjusting their sleep cycles to their daily schedule.

All human beings possess a body clock. Along with other alerting systems, this governs the sleep/wake cycle and is therefore one of the main processes which govern sleep behaviour. Typically, the preferred sleep/wake cycle is delayed in adolescents, which leads to many students not feeling sleepy until much later in the evenings. This typical sleep pattern is usually referred to as the “night owl” schedule of sleep.

This is opposed to the “early bird” schedule, and is a kind of disorder where the individual tends to stay up much past midnight. Such a person has great difficulty in waking up in the mornings. Research suggests that night owls feel most alert and function best in the evenings and at night. Research findings have shown that about 20 percent of people can be classified as “night owls” and only 10 percent can be classified as “early birds” ------ the other 70 percent are in the middle. Although this is clearly not true for all students, for the ones who are true night owls, this gives them an excellent excuse for missing their lectures which unfortunately fall before midday.

【4】B

【解析】

試題分析: 本文屬于說明文范疇。在文中作者通過介紹一堂課中學生遲到和準時到的情況，提出了學生不擅長調(diào)整自己的生物鐘而去適應白天的學業(yè)安排。然后在文中分析了目前青少年睡眠存在的問題，提出了兩種不同的睡眠模式，即“early bird ”（早起型） 和“night owl”（夜貓子型），并主要介紹了晚上不困，白天困的“night owl” 現(xiàn)象。

【1】C考查主旨大意。在文章首段作者首先通過數(shù)字說明許多學生早晨不能準時起床的一種情況，然后用一句話Obviously, students are terrible at adjusting their sleep cycles to their daily schedule.來解釋這種現(xiàn)象的原因，提出文章中心，然后圍繞此中心展開行文，故答案選C。

【2】D考查細節(jié)理解。根據(jù)第二段Typically , the preferred sleep / wake cycle is delayed in adolescents …可知學生們對他們自己的睡眠模式不熟悉，沒有能夠恰當?shù)厝フ{(diào)整適應自己的生物鐘，因而造成了睡眠問題，故答案選D。

【3】B考查詞義推斷。A批評；B分類；C 組織；D命名。根據(jù)上文第三段末句This typical sleep pattern is usually referred to as the "night owl" schedule of和第四段首句This is opposed to the "early bird" schedule,可知睡眠模式有兩種，即”night owl” 和”early bird”，而此處把20%歸到night owls類，由此判斷該詞意思為“分類”，選B。

【4】B考查主旨要義。在文章開頭介紹一堂課中學生的遲到和準時到的情況，提出了學生不擅長調(diào)整自己的生物鐘而去適應白天的學業(yè)安排這一問題。然后在下文對此現(xiàn)象進行分析并介紹造成這種情況的原因，所以答案選B。A選項內(nèi)容“人體生物鐘的功能”，B選項“人體的睡眠行為”都比較片面，不能反應文章中心；而D選項“早起者的時間安排”在文中沒有涉及
