Vending machines （投币式自动售货机） are found in 16% of U．S．elementary schools, 52% of middle schools and 88% of high schools．About 22% of students in grades 1 through 12 buy food in vending machines each day—and those purchases added an average of 253 calories to their diets, according to a new study in the September issue of the Journal of School Health．
Just to be clear, those were not 253 calories' worth of tofu, yogurt or carrot．The most popular vending machine items included soft drinks, candy, chips, crackers, cookies, cakes and ice cream．On the plus side （好的方面）, kids also bought low-fat milk, fruit juice and even fruit, the study found．
But the eventual effect on kids' diets was not good．Those who bought from vending machines ate an average of 156 grams of sugar per day, compared with 146 grams for those who abstained （节制）．They also consumed less fiber, iron and vitamin B．
One silver lining: Vending machine customers ate 4% less sodium （钠） than other students--an average of 3,287 milligrams per day compared with 3,436 mg for those who didn't buy from vending machines．That's probably because the extra snacks made kids too full to eat as much at mealtimes, when dishes are especially Salty．In any event, kids should eat no more than 1,200 to 1,500 mg of sodium each day, according to the Mayo Clinic．Even for adults, the government recommends a daily limit of 2,300 mg．
Overall, vending machines in school appear to be a threat to children's health．The researchers calculated that all that snacking adds up to about14 extra pounds per child per school year．For some students this might be a serious contributor to weight issues．The study was based on data collected from 2,309 children nationwide for the third School Nutrition Dietary Assessment Study, which was
conducted by the U．S．Department of Agriculture's Food and Nutrition Service．

One school night this month I walked quietly up to Alexander, my 15-year-old son, and touched his cheek gently in a manner I hoped would seem casual．A year ago he would have ignored this disturbance but now he reacted impatiently and leaned back to his computer screen．
I made a mistake: breaking into my teenager's personal space. “The average teenager has pretty strong feelings about his privacy," Lara Fox and her friend Hilary Frankel told me. Mr．Frankel and Mr．Fox, both 17, are the authors of Breaking the Code, a new book that seeks to bridge the generational divide between parents and adolescents．It is being promoted by its publisher as the first self-help guide by teenagers for their parents, a kind of "Kids Are From Mars, Parents Are From Venus" that explains the language and actions of teenagers．The girls dealt with issues including hanging out late, money, school pressures, smoking etc．
Personally, I welcome their opinions．The most common missteps in interacting with teenagers arise from the war between parents exercising their rights to know what goes on under their roof and teenagers firmly guarding their privacy．Teenagers can be quick to interpret their parents' remarks and respond with anger that masks their vulnerability （脆弱 ）. Ms Fox said, "What we want above all is your approval．Don't forget, no matter how much we act as if we don't care what you say, we believe the things you say about us．"
Nancy, a New York child-raising expert said she didn't agree with everything the authors suggested but found their arguments reasonable．"When your kids are saying, ' You don't get it, and you never will, ' there are lots of ways to respond so that they will listen and that is what the writers point out．"
" My parents helped me see that, " Mr．Fox told me, " even though they used to stay out late and ride their bicycles to school, times have changed and the way parents educate children is different．These days there is a major fear factor in bringing up kids．Parents worry about their child crossing the street．" The writers said they hoped simply to throw light on teenage thinking．
1.According to the two girls, teenagers nowadays are ____．
A．independent B．intelligent
C. inconsiderate D．sensitive

A．the teenagers don't want/to admit their weakness

D．the generation gap cannot be shortened despite their parents' efforts
3.It can be inferred from the last two paragraphs that ____．
A．teenagers should guard their privacy
B．Nancy totally agrees with the two girls' opinions
C．parents are more concerned about children's safety
D．the two girls have obtained numerous support from the public
4.Why does the author mention the book "Kids Are From Mars, Parents Are From Venus ?
