根据短文内容,从短文前方框内的选项中选出能填入空白处的最佳选项。
A. Half said that they feel tired after getting up and 15 percent people have trouble falling
asleep.
B. Above all, get enough sleep.
C. Enough sleep helps the body and brain grow and develop.
D. The lights keep their brains excited for a long while.
E. The report said that this is one of the main reasons for bad sleep.
Sleep is like food for the brain. 66 However, many Chinese do not sleep well, and many
do not pay enough attention to sleep.
According to the 2013 China Sleep Quality Index (指数), nearly a quarter of Chinese people
don't sleep well. 67
Ye Jingying, a sleep expert at Beijing Tongren Hospital, says, “If people often wake up during
the night, or always feel weak and tired in the day, they should pay attention to their sleep pattern
(模式).”
Many people play with their cell phones or iPads before sleeping. 68 Other reasons
include stress and bad moods.
How to sleep well? 69 Seven to nine hours of sleep every night is perfect for an adult,
and eight to nine hours is best for a teenager.
Forming good sleep habits is important. The report suggested that people need to keep away
from digital devices (数码产品) for at least an hour before sleep. 70 Other suggestions
include: try to go to sleep and wake up at the same time every day, even on weekends and during
holidays, and do the same relaxing things before bed each night, like listening to soft music.
