Question

C

Students who stay up late to prepare for a test or finish a project have lower comprehension and worse performance in the classroom, research shows. The old saying "you snooze, you lose" doesn't apply to students who stay up late to prepare for a test or finish a class project.

The UCLA team found that a student who gives up sleep for extra study time will have trouble the next day understanding material in class and be more likely to struggle with an assignment or a test―the opposite of the student's intent.

The researchers didn't quantify(量化)the increased risk for academic problems following a longer-than-usual study session, but they said the number of problems was surprisingly greater.

When she stayed up late to study, Kai Daniels had more trouble ab?sorbing material in class. "I'd have to re-teach myself at night,"she said. The finding makes a lot of sense, and several new studies are showing that the quantity and the quality of sleep are important for remembering new infor?mation and consolidating(鞏固)learning.

Students who get too little sleep don't have enough time to process what they study; even just one night of sleep deprivation(剝奪)can have a negative effect. Parents should do what they can to make sure their children have enough sleep. Most adolescents need just over nine hours of sleep a night,which 9% of high school students actually get, according to the Na?tional Sleep Foundation. "Though a regular sleep time is necessary, it's hard for those students who are racing to enter college to put it into prac?tice," the researchers wrote.

10 What does the example of Kai Daniels prove in Paragraph 4? „

A.The importance of staying up late to study.         

B.The importance of the quantity and the quality of sleep.

C The importance of remembering new information.

D. The importance of consolidating learning.

11.Why can't most students in high school get enough sleep?

A. Because they should obey school rules.

B. Because their parents force them to stay up late.

C.Because they obey the rules of the National Sleep Foundation.

D.Because they face great pressure to go to college.

Answer 1

C

[文章大意]本文是一篇科普文章，介紹了學(xué)生為了學(xué)習(xí)而減少睡眠，結(jié)果會適得其反。

8. D推理判斷題。文章第一段談到睡眠不足造成考試成績差，課堂學(xué)習(xí)時理解能力下降。"你打盹，就不會贏了"這個格言對于為了考試或完成一個項目而熬夜的學(xué)生并不適用。由此斷定，為了學(xué)習(xí)而犧牲睡眠并不是一項劃算的交易。

9.C

 10.B推理判斷題。根據(jù)第四段最后一句可知：幾項新研究顯示，睡眠數(shù)量和質(zhì)量對記憶新知識和鞏固學(xué)習(xí)內(nèi)容都很重要。由此斷定正確答案為B。

11.D細(xì)節(jié)理解題。文章最后一段后半部分談到：根據(jù)全國睡眠基金會報告，大多數(shù)青少年一晚需要九小時以上的睡眠，但只有9%的高中生能達(dá)到這樣的睡眠時間。研究人員寫道：盡管規(guī)律的睡眠時間是必要的，但是高中生面臨巨大的升學(xué)壓力，很難將此付諸實(shí)踐。由此斷定正確答案為D。
