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. is a good trade B.is a special trade

9. Students give up their sleep just_ __ .
A. to understand material in class
B. to get more time to play

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.
