Question

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．
67．The text mainly deals with the relation between children'sD．
A．reading abilities and their sleeping habits
B．mental development and their sleeping habits
C．behaviour and their studying habits
D．performance in learning and their sleeping habits
68．The underlined word"They"in the third paragraph refers to"B"
A．the findings                     
B．the researchers
C．the seven-year-olds             
D．the sleep patterns             
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
B．girls with regular bedtimes perform better in learning than boys
C．girls with irregular bedtimes do worse in reading than boys
D．the gap between girls with and without regular bedtimes is larger than that between boys．

解答 67-70．DBCD
67题答案：D考查细节推理，根据文章第二段的The findings on sleep patterns and brain power come from a UK study of more than 11，000 seven-year-olds．
关于睡眠方式与脑力的研究结果来自对英国超过11000名7岁儿童的研究．可知本题答案为D选项．
68题答案：B考查细节推理，根据划线词所在的句子Theygathered information on the children at the ages of three…（他们收集三岁孩子…的信息）及上面的"研究结果来自对超过11000名孩子的研究"可知they指的是"研究者"；故本题答案为B选项．
69题答案：C考查细节推理，根据第四段的By the age of seven，more than half the children had a regular bedtime of between 19：30 and 20：30．到七岁的时候有超过一半的孩子的睡觉时间是规则的（在19：30-20：30之间）．可知"一大半的孩子直到7岁才有规则的睡觉时间"，故本题答案为C选项．
