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(巩固)learning.

Students who get too little sleep don't have enough time to process what they study; even just one night of sleep deprivation(剥夺)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.

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?

Answer 1

C

[文章大意]本文是一篇科普文章，介绍了学生为了学习而减少睡眠，结果会适得其反。

8. D推理判断题。文章第一段谈到睡眠不足造成考试成绩差，课堂学习时理解能力下降。"你打盹，就不会赢了"这个格言对于为了考试或完成一个项目而熬夜的学生并不适用。由此断定，为了学习而牺牲睡眠并不是一项划算的交易。

9.C

 10.B推理判断题。根据第四段最后一句可知：几项新研究显示，睡眠数量和质量对记忆新知识和巩固学习内容都很重要。由此断定正确答案为B。

11.D细节理解题。文章最后一段后半部分谈到：根据全国睡眠基金会报告，大多数青少年一晚需要九小时以上的睡眠，但只有9%的高中生能达到这样的睡眠时间。研究人员写道：尽管规律的睡眠时间是必要的，但是高中生面临巨大的升学压力，很难将此付诸实践。由此断定正确答案为D。
