The liquid fills their tiny stomachs and ruins their appetite (胃口)for foods with needed nutrients (营养物)and calories. According to a study published in Pediatrics(小儿科), the resulting malnutrition(营养不良)can prevent babies from developing normally. Dr.Fima Lifshitz and a colleague at Maimonides Medical Center in Brooklyn, N.Y., examined eight children, ages 14 months to 27 months, whose growth had lagged behind their peers. Each was drinking 12 to 30 ounces of juice a day. After recording what else the children ate, researchers realized that the fruit beverages(饮料)accounted for 25 to 60 percent of the daily calorie consumption (热能消耗量). Soon after parents gave their children less juice and more milk, the children gained weight.Health professionals say babies under six months shouldnt drink juice; some pediatricians (儿科医师)suggest waiting until after the first birthday. Whenever they start, young children shouldnt have more than a few ounces a day.1.

The schools and the educators made it easy on us. They taught that it was all right to be parents who take a let-alone policy. We stopped making our children do homework. We gave them calculators, turned on the television, left the teaching to the teachers and went on holiday.Now teachers, faced with children who have been developing at their own pace for the past 15 years, are realizing weve made a terrible mistake. One such teacher is Sharon Klompus who says of her students-“so inactive”-and wonders what happened. Nothing was demanded of them, she believes. Television, says Klompus, leads to childrens inactivity. “Were not training kids to work any more,” says Kolmpus. “Were talking about a generation of kids who have never been hurt or hungry. They have learned somebody will always do it for them. Instead of saying go look it up, you tell them the answer, it takes greater energy to say no to a kid.”Yes, it does. It takes energy and it takes work. Its time for parents to end their holiday and come back to work. Its time to take the car away, to turn the TV off, to tell them it hurts you more than them but its for their own good. Its time to start telling them no again.6We learn from the passage that the authors mother used to _.a. demand her child to do too much hard workb. be a teacherc. be easy on her childd. be strict with her child7. By “permissive period in education” the author means a time _.a. when children achieve their best in schoolb. when everything can be taught at schoolc. when every child can be educatedd. when children are allowed to do what they wish to8. Children are becoming more inactive in study because _.a. they watch TV too oftenb. they have done too much homeworkc. they have to fulfill too many duties d. teachers are not strict with them9. To such children as described in the passage _.a. it is easier to say yes than to say nob. it is easier to say no than to say yesc. neither is easy-to say yes or to say nod. neither is difficult-to say yes or to say no10. The main idea of the passage is that _.a. its time to be more strict with our kidsb. parents should leave their children alonec. kids should have more activities at school d. parents should always set a good example to their kids二. 介词填空: （按第2册课本第1-2单元课文内容填入适当的介词）11.
