5.Youngsters who have no regular bedtime or who go to bed later than 21:00 have lower scores for reading and maths.Lack of sleep may influence how well the brain learns new information.
The findings on sleep patterns and brain power come from a UK study of more than 11,000 seven-year-olds.
Theygathered information on the children at the ages of three,five and seven to find out how well they were doing with their learning and whether that might be related to their sleeping habits.
Establishing (制定) a good bedtime routine early in childhood is important.Irregular bedtimes were most common at the age of three,when around one in five of the children went to bed at varying times.By the age of seven,more than half the children had a regular bedtime of between 19:30 and 20:30.
Children with irregular bedtimes tended to be less successful than their playmates in terms of test scores for reading,maths and spatial awareness(空间想象).The influence was more obvious throughout early childhood in girls than in boys and appeared to be increasing.
The researchers said it was possible that irregular bedtimes were a reflection of chaotic (无秩序的) family settings and they had an influence on cognitive (认知的) performance in children.The children with late and irregular bedtimes came from more socially disadvantaged backgrounds and were less likely to be read to each night and,generally,watched more TV.After controlling for such factors,the link between poorer mental performance and irregular bedtimes remained.

A.reading abilities and their sleeping habits
B.mental development and their sleeping habits

D.performance in learning and their sleeping habits

A.the findings

69.Which of the following is TRUE according to the text?C
A.About one third of the three-year-olds go to bed at irregular bedtimes.
B.Irregular bedtimes were most common before the children were three months old.
C.More than half the children didn't have a regular bedtime until they were seven years old.
D.Teachers should help their kids establish a good bedtime routine early in childhood.
70.We can know from the text thatD.
A.boys with irregular bedtimes do worse in reading than their playmates
