A new survey of 100 hard-working mothers shows that they spend about 70 hours a week doing chores and looking after their families.
They spend more than ten hours a day cooking, cleaning the house, getting children ready for school and helping with homework. Cooking takes up (占用) about one hour and nine minutes a day. Doing the laundry takes about 61 minutes. Mothers also spend about 55 minutes getting children ready for school, about 53 minutes putting them to bed and about 47 minutes helping with homework.
However, 30% of those mothers with children under 16 get less than six hours’ sleep at night. 83% are not happy because they have less than an hour of their own(自己的) time every day. Only 17% are happy with this kind of life.
【小題1】In the survey, mothers spend about 70 hours a week __________.

A．going shopping	B．doing chores
C．looking after their families	D．Both B and C

【小題2】It takes mothers _________ to cook every day.

A．a(chǎn)bout 69 minutes	B．a(chǎn)bout 55 minutes
C．a(chǎn)bout 47 minutes	D．a(chǎn)bout 10 hours

【小題3】In the survey, ________ mothers with children under 16 sleep less than six hours at night.

A．100

B．70

C．83

D．30

【小題4】From the survey, we know that _________________.

A．no mothers like this kind of life

B．a(chǎn) few mothers are hard-working

C．most mothers want to have more time to do their own things

D．a(chǎn)ll mothers would like to work harder

A Brown University sleep researcher has some advice for people who run high schools: Don’t start classes so early in the morning. It may not be that the students who nod off at their desks are lazy. And it may not be that their parents have failed to enforce(確保) bedtime. Instead, it may be that biologically(生物學(xué)上)these sleepyhead(貪睡者)students aren’t used to the early hour.
　　“Maybe these kids are being asked to rise at the wrong time for their bodies,” says Mary Carskadon, a professor looking at problem of adolescent (青春期的)sleep at Brown’s School of Medicine.
　　Carskadon is trying to understand more about the effects of early school time in adolescents. And, at a more basic level, she and her team are trying to learn more about how the biological changes of adolescence affect sleep needs and patterns(方式).
　　Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less, as commonly thought.
　　Sleep patterns change during adolescence, as any parent of an adolescent can prove. Most adolescents prefer to stay up later at night and sleep later in the morning. But it’s not just a matter of choice---their bodies are going through a change of sleep patterns.
　　All of this makes the transfer(遷移)from middle school to high school---which may start one hour earlier in the morning----all the more difficult, Carskadon says. With their increased need for sleep and their biological clocks set on the “sleep late, rise late” pattern, adolescents are up against difficulties when they try to be up by 5 or 6 a.m. for a 7:30 a.m. first bell. A short sleep on a desktop may be their body’s way of saying. “I need a timeout.”
【小題1】Carskadon suggests that high schools should not start classes so early in the morning because _______.

A．it is really tough for parents to enforce bedtime

B．it is biologically difficult for students to rise early

C．students work so late at night that they can’t get up early

D．students are so lazy that they don’t like to go to school early

【小題2】The underlined phrase nod off most probably means _______.

A．turn around

B．a(chǎn)gree with others

C．fall asleep

D．refuse to work

【小題3】What might be a reason for the hard transfer from middle school to high school?

A．Adolescents depend more on their parents.

B．Adolescents have to choose their sleep patterns.

C．Adolescents sleep better than they did at childhood.

D．Adolescents need more sleep than they used to.

【小題4】What is the test mainly about?

A．Adolescent health care.

B．Problems in adolescent learning.

C．Adolescent sleep difficulties.

D．Changes in adolescent sleep needs and patterns.

A recent study offers a picture of how dangerous it is to get a lift from a teenage driver. Indeed, a 16-year-old driver with three or more passengers is three times as likely to have a fatal（致命的）accident as a teenager driving alone. However, the possibility of death for drivers between 30 and 59 decreases with each additional (added) passenger.
　　It was also found that the death rates for teenage drivers increased greatly after 10 p.m., and especially after midnight. With passengers in the car, the driver was even more likely to die in a late night accident.
　　Robert Foss, a scientist at the University of North Carolina Highway Safety Research Center, says the higher death rates for teenage drivers have less to do with “really stupid behavior” than with just a lack of driving experience. Both he and the author of the study believe that the way to help solve the problem is to have states setting up so-called graduated licensing systems（等級(jí)執(zhí)照制）. A graduated license requires that a teenager first prove that he/she is able to drive in the presence of an adult, followed by a period of driving with a limited number of passengers, before graduating to full driving on his own. About half of the states now have some sort of graduated licensing system in place. The systems have reduced teenage driver crashes（相撞）, according to recent studies.
【小題1】Which of the following situations is most dangerous according to the passage?

A．Adults giving a lift to teenagers on the highway after 10 p.m.

B．A teenager driving after midnight with passengers in the car.

C．Adults driving with three or more teenage passengers late at night.

D．A teenager getting a lift from a stranger on the highway at midnight.

【小題2】According to Robert Foss, the high death rate of teenage drivers is mainly because __.

A．their preference for driving at night

B．their lack of driving experience

C．their careless way of driving

D．their driving with passengers
