On average, American kids ages 3 to 12 spent 29 hours a week in school, eight hours more that they did in 1981. They also did more household work and participated in more of such organized activities as soccer and ballet (芭蕾舞). Involvement in sports, in particular, rose almost 50% from 1981 to 1997: boys now spend an average of four hours a week playing sports; girls log hall that time. All in all, however, children’s leisure time dropped from 40% of the day in 1981 to 25%“Children are affected by the same time crunch (危机) that affects their parents,” says Sandra Hofferth, who headed the recent study of children’s timetable. A chief reason, she says, is that more mothers are working outside the home. (Nevertheless, children in both double-income and “male breadwinner” households spent comparable amounts of time interacting with their parents 19 hours and 22 hours respectively. In contrast, children spent only 9 hours with their single mothers.)All work and no play could make for some very messed-up kids. “Play is the most powerful way a child explores the world and learns about himself,” says T. Berry Brazelton, professor at Harvard Medical School Unstructured play encourages independent thinking and allows the young to negotiate their relationships with their peers, but kids ages 3 to 12 spent only 12 hours a week engaged in it.The children sampled spent a quarter of their rapidly decreasing “free time” watching television. But that, believe it or not, was one of the findings parents might regard as good news. If they’re spending less time in front of the TV set, however, kids aren’t replacing it with reading. Despite efforts to get kids more interested in books, the children spent just over an hour a week reading. Let’s face it, who’s got the time?1. By mentioning “the same time crunch” (Line 1, Para. 2) Sandra Hofferth means ________.A) children have little time to play with their parentsB) children are not taken good care of by their working parentsC) both parents and children suffer from lack of leisure timeD) both parents and children have trouble managing their time2. According to the author, the reason given by Sandra Hofferth for the time crunch is ________.A) quite convincingB) partially trueC) totally groundlessD) rather confusing3. According to the author a child develops better if ________.A) he has plenty of time reading and studyingB) he is left to play with his peers in his own wayC) he has more time participating in school activitiesD) he is free to interact with his working parents4. The author is concerned about the fact that American kids ________.A) are engaged in more and more structured activitiesB) are increasingly neglected by their working mothersC) are spending more and more time watching TVD) are involved less and less in household work5. We can infer from the passage that ________.A) extracurricular activities promote children’s intelligenceB) most children will turn to reading with TV sets switched offC) efforts to get kids interested in reading have been fruitfulD) most parents believe reading to be beneficial to children
A) nonviolent B) notification C) dubbed D) sessionsE) purposefully F) surprising G) expired H) directedI) positive J) casually K) notion L) proportionedM) ambiguous N) influenced O) entitiesThere is nothing new about TV and fashion magazines giving girls unhealthy ideas about how thin they need to be in order to be considered beautiful. What is _1_ is the method psychologists at the University of Texas have come up with to keep girls from developing eating disorders. Their main weapon against superskinny (role) models: a brand of civil disobedience _2_ “body activism.”Since 2001，more than 1,000 high school and college students in the U.S. have participated in the Body Project, which works by getting girls to understand how they have been buying into the _3_ that you have to be thin to be happy or successful. After critiquing (评论）the so-called thin ideal by writing essays and role-playing with their peers, participants are _4_ to come up with and execute small,_5_acts. They include slipping notes saying “Love your body the way it is” into dieting books at stores like Borders and writing letters to Mattel, makers of the impossibly _6_ Barbie doll.According to a study in the latest issue of the Journal of Consulting and Clinical Psychology, the risk of developing eating disorders was reduced 61% among Body Project participants. And they continued to exhibit _7_ body-image attitudes as long as three years after completing the program, which consists of four one-hour _8_. Such lasting effects may be due to girls’ realizing not only how they were being _9_ but also who was benefiting from the societal pressure to be thin.“These people who promote the perfect body really don’t care about you at all，” says Kelsey Hertel, a high school junior and Body Prqject veteran in Eugene, Oregon. “They _10_ make you feel like less of a person so you’ll buy their stuff and they’ll make money.”
翻译题：The English ceremony of afternoon tea dates back to the 1840s. The tradition evolved out of the rituals and routines that surrounded tea drinking in Britain before that time. Tea was first introduced to England in the late 1650s, but for a long time, it was only consumed by the royal family and the aristocracy due to its high cost. The habit of having afternoon tea did not become established until almost 200 years later. In those days, the British ate only two daily meals: a large breakfast late in the morning and a late dinner around 8 o'clock in the evening. Anna, the 7th Duchess of Bedford, can be credited for creating the tradition of afternoon tea to soothe hunger pangs before supper. She invited friends to join her for an additional afternoon meal at four to five o'clock. The menu included tea and snacks such as dainty cakes and sandwiches. Fine porcelain (瓷器) was used to serve this minor feast. Afternoon tea soon became popular, and is now a symbol of the elegant British way of life. As novelist Henry James wrote, "There are few hours in life more agreeable than the hour dedicated to the ceremony known as afternoon tea."
