balanced diet.阅读理解ATeenagers who spend hours in front of the television may have a poorer diet as young adults.A study，which included nearly 1,400 high school students，found those who watched TV for five hours or more per day had less healthy diets than peers(同龄人)five years later.Why does this happen？Should the parents take any measures?On the one hand，people who spend a lot of time in front of the TV，especially teenagers，may snack more，and that may affect their longterm diet quality. On the other hand，TV ads for fast food，sweets and snacks tempt teenagers to eat more of those foods.And TV time might also replace exercise time for some kids.Lead researcher Dr.Daheia JBarrAnderson，of the University of Minnesota in Minneapolis，told Reuters Health a clear correlation between TV time during high school and diet quality in young adulthood.While the heaviest TV viewers were eating the most junk food，those whod watched less than two hours per day had the highest intake(吸收)of fruits，vegetables，whole grains and highcalcium food.In her opinion，parents should limit and monitor TV viewing.As far as I am concerned，children should watch no more than two hours of television per day.And parents should set a good example by eating right，being physically active and curbing their own TV time.1Whats the best title for this passage?APeople Should Keep Away from TV to Keep HealthyBTeenagers TV Time May Affect Their Diets LaterCWhy Do Teenagers Like TV?DParents Own Habits May Affect Children Later答案B解析标题归纳题。根据全文主题句，即第一段“Teenagers who spend hours in front of the television may have a poorer diet as young adults.”可知，在电视机前待几个小时的青少年可能会饮食差。故选B。2According to the passage，heavy TV viewers tend to .Aeat more fruitsBeat less junk foodCtake in fewer vegetablesDtake in highcalcium food答案C解析推理判断题。根据第五段第二句“While the heaviest TV viewers were eating the most junk food，those whod watched less than two hours per day had the highest intake(吸收) of fruits，vegetables，whole grains and highcalcium food.”可知，看电视多的观众在吃垃圾食品时，那些每天看电视少于两小时的人得到的是水果、蔬菜、全谷物和高钙食品的吸收。故选C。3What suggestion does the author give the parents?AThey must watch TV with their children.BThey should forbid the children to watch TV.CThey should pay attention to nutrition in diets.DThey cant do what they dont want their children to do.答案D解析细节理解题。根据最后一段中的“And parents should set a good example by eating right，being physically active and curbing their own TV time.”可知，父母应该通过合理饮食，积极锻炼身体，控制自己看电视的时间为孩子树立一个好的榜样。故选D。4The underlined word “curbing” in the last paragraph can be replaced by “ ”Aadding BcheckingCcontrolling Dstopping答案C解析词义猜测题。纵观全文，特别是文章最后一句可知父母要为孩子树立榜样，父母通过合理饮食，积极锻炼身体和控制自己看电视的时间来为孩子树立一个好榜样。故选C。BTo American visitors，Iceland is a very interesting country，partly because it is different in so many ways from what he or she is used to seeing at home.There are quite a few things that are not done，or that do not exist on the islandquite a few “Nos”There is no pollution，for instance.No dogs are permitted in Reykjavik，the capital.There is no television on Thursdays or during the entire month of July，and only three hours of blackandwhite TV the rest of the time.There is no hard liquor(烈酒) on Wednesdays and no beer at any time.There are no handguns，only one jail of thirtyfive cells(狱室) in the entire landan admirable figure，even for a small country of 313,376 people.There is no army，air force or navy.There is no tipping for anything.There are no large stores open on Saturdays or Sundays.Since Iceland is situated just under the Arctic Circle，there is no darkness in summer and no daylight in winter.But thanks to Culf Stream，the climate is rather mild，with temperatures ranging from 34 degrees to 52 degrees in July.The rules on television，liquor and guns are the result of government decisions.But the absence of pollution is due in great part to the fact that Iceland gets its power from the enormous geyser and the thousands of hot springs that come out of the ground.They provide all the energy needed by the country.In fact，Iceland uses only 3 percent of all the available power of its hot springs.Iceland has been described as a democratic independent country where more fish are caught and more books are published per person than anywhere else in the world.The Icelanders h
