For questions 1-7, mark： Y (for YES) if the statement agrees with the information given

3、 in the passage; N (for NO) if the statement contradicts the information given in the passage; NG (for NOT GIVEN) if the information is not given in the passage. 1 Generation XXL A society of obese children Childrens impulses havent changed much in recent decades. But social forces from the disappea

4、rance of home cooking to the rise of fast food and video technology - have converged to make them heavier. Snack and soda companies are spending hundreds of millions a year to promote empty calories, while schools cut back on physical education and outdoor play is supplanted by Nintendo(任天堂游戏机 ) and

5、 Internet. By the governments estimate, some 6 million American children are now fat enough to endanger their health. An additional 5 million are on the threshold, and the problem is growing more extreme even as it becomes more widespread. “The children we see today are 30 percent heavier than the o

6、nes who were referred to in 1990,“ says Dr. Naomi Neufeld, a pediatric endocrinologist(儿科内分泌学家 ) in Los Angeles. Obese kids suffer both physically and emotionally throughout childhood, and those who remain heavy as adolescents tend to stay that way into adulthood. The resulting illnesses diabetes(糖尿

7、病 ), heart disease, high blood pressure, several cancers now claim an estimated half-million American lives each year, while costing us $ 100 billion in medical expenses and lost productivity. U.S. Agriculture Secretary Dan Glickman predicts that obesity will soon rival smoking as a cause of prevent

8、able death, and some health experts are calling for national action to combat it. Meanwhile, the challenge for children and their parents is to swim against the current. Until recently, childhood obesity was so rare that no one tracked it closely. Body-mass index (BMI), the height-to-weight ratio us

9、ed to measure adult weight, seemed irrelevant to people whose bodies are still growing. But that mind-set is changing. In a gesture aimed at parents and pediatricians(儿科医师 ), federal health officials recently published new growth charts that extend the BMI system to children. Unlike the adult charts

10、, which classify anyone with a BMI of 25 or higher as “overweight“ and anyone with a BMI of 30 or more as “obese,“ the childhood charts use population norms from the 1960s to determine healthy weight ranges for kids 2 to 20. According to the new charts, a typical 7-year-old girl stands 4 feet 1 inch

11、 tall and weighs 50 pounds, giving her a BMI of 15. By the age of 17, she stands 5 feet 4 and weighs 125 pounds, for a BMI of 21. To spare parents undue alarm over baby fat or the normal weight gain that precedes growth spurts(冲刺 ), the new charts use a broad definition of healthy weight. The heavy

12、sufferings Even by these lenient(宽松的 )standards, the proportion of kids who are overweight jumped from 5 percent in 1964 to nearly 13 percent in 1994, the most recent year on record; If the trend has continued and many experts believe it has accelerated one child in three is now either overweight or

13、 at risk of becoming so. No race or class has been spared, and many youngsters are already suffering health consequences. Dr. Nancy Krebs, a pediatrician at the University of Colorado, notes that overweight children are now showing up with such problems as fatty liver, a precursor(先兆 )to cirrhosis (

14、硬化 ), and obstructive sleep apnea(呼吸暂停 ), a condition in which the excess flesh around the throat blocks the airway, causing loud snoring, fitful sleep and a chronic lack of oxygen that can damage the heart and lungs. Even Type 2 diabetes known traditionally as “adult-onset“ diabetes turn up in over

15、weight kids. “Ten years ago 1 would have told you that Type 2 diabetes doesnt occur until after 40,“ says Dr. Robin Goland of New Yorks Columbia-Presbyterian Hospital, “Now 30 percent of our pediatric patients are Type 2.“ Unlike Type 1 disease, in which the pancreas(胰腺 ) fails to produce the insuli

16、n(胰岛 素 ) needed to transport sugar from the bloodstream into cells, Type 2 diabetes occurs when a persons cells grow resistant to insulin, causing sugar to build up in the blood. Unless its carefully managed, this obesity- related condition can damage blood vessels Within a decade, setting the stage

17、 for kidney failure and blindness as well as amputations(截肢手术 ), heart attacks and strokes. And because children are not routinely screened for Type 2 disease, Goland worries that many cases are going undiagnosed. Even if they dont develop diabetes, chronically overweight kids may become prime candi

18、dates for heart attacks and strokes. In a recent survey of preschoolers at New York City Head Start Centers, Dr. Christine Williams of Columbia University found that overweight kids as young as 3 and 4 showed signs of elevated blood pressure and cholesterol(胆固醇 ). “Theres a lag between the developme

19、nt of obesity and the chronic diseases associated with it,“ says Dr. William Dietz of the Centers for Disease Control and Prevention. “Were in that trough right now. Very soon well see the rate of cardiovascular(心脏血管的 ) disease among teenagers rising.“ Obesity a struggle of the whole society How doe

20、s a child end up in this predicament? Genes are clearly part of the story. Nine-year-old Emily Hoffman of Humble, Texas, was born weighing nearly 11 pounds. And though she Was raised in ways her pediatricians approved of, everything she ate seemed to turn into fat. By 7 she weighed 180 pounds. But e

21、ven in kids who are prone to obesity, lifestyle is what triggers it. Felice Ramirez weighed 200 pounds when she started eighth grade in Victoria, Texas, three years ago. And though she has since lost 25, she is constantly influenced in the wrong direction. She has a P.E. class at school, but sitting

22、 on the bleachers counts as participation. And though the school cafeteria tries to offer healthy fare, the lines are so long, and the lunch period so short, that kids are often forced to dine on packaged snacks from the vending machines. These are common temptations. Many schools now feature not on

23、ly soda and snack machines but on- site outlets for fast-food chains. At the same time, recess and physical education are vanishing from the schools standard curriculum. Not surprisingly, the proportion of high-school kids in daily gym classes fell from 42 percent to 29 percent during the 90s. 2 The
