5．ASK any group of teenagers in the UK what they most like to eat，and foods like pizzas，curries，pasta，burgers and chips are bound to get a mention-and many young people would probably also list hanging out at the local fast-food restaurant as one of their favorite pastimes．
But what teenagers like to eat is not necessarily what they should be eating．According to the National Diet and Nutrition Survey，far too many young people in the UK between the ages of four and 18consume too much fat，sugar and salt in their diet and take in too many calories．Meanwhile their intake of starchy carbohydrates （淀粉類碳水化合物），fibre，iron，vitamins and calcium is too low．
For a growing body，eating foods containing plenty of calcium，such as milk，yoghurt and cheese，is particularly important as calcium is essential for the development of healthy，strong bones．Similarly，foods that are rich in iron are good for young，rapidly developing bodies，so red meat，bread，green vegetables，dried fruit and fortified （強化的） breakfast cereals （谷類食物） are also recommended．
It is during our teenage years that lifestyle habits can become entrenched （根深蒂固的），so it is important that young people are educated about what foods are good for them．In 2005，in an attempt to change eating habits and open teenagers'minds to new flavors and new tastes，celebrity chef Jamie Oliver launched a‘Feed Me Better'campaign．As part of a television series，‘Jamie's School Dinners'，he worked with teachers and cooks in a number of schools across the UK to provide more healthy，nutritious school meal options．Although the campaign was rather resisted at the beginning，it was generally regarded as a huge success and helped to influence governmental policy on nutritional standards for school meals．
No one expects to end the teenage love affair with fast and junk food but，hopefully，if projects like‘Feed Me Better'and the Government's own‘Change4Life'campaign continue to give out the right messages，more young people will understand the importance of balancing occasional treats with healthier food options．

分析 本文是一篇科教類閱讀，文章主要介紹了在調查英國的年輕人最喜歡什么食物時，發(fā)現(xiàn)他們最喜歡吃快餐和不健康的食物，這是由于他們的飲食習慣造成的，文章例舉垃圾食品給青少年的成長帶來的危害，呼吁年輕人多吃營養(yǎng)的食物．在2005年，為了改變年輕人的飲食習慣和擁有新的飲食認識，一名叫杰米的廚師開創(chuàng)了"Feed Me Better"這個項目，呼吁年輕人為了強壯的身體應該多吃鈣和鐵．這項活動最終還是取得了很大的成就．由此得出，由于我們的生活習慣會不斷發(fā)展變化，因此教育孩子們吃好是很重要的．
解答 ABDC
50．A細節(jié)理解題．根據(jù)前兩段的內容可知，詢問英國任何一個青少年他們最喜歡吃的食物，和喜歡的披薩，面食，總會提到漢堡和薯條．許多年輕人也可能會列出本地快餐店作為他們最喜歡的地方．而年輕人喜歡吃的并不是他們應該吃的．由此可知，英國的年輕人吃的太多的是垃圾食品．故選A．
51．B細節(jié)判斷題．根據(jù)第三段calcium is essential for the development of healthy，strong bones．Similarly，foods that are rich in iron are good for young，rapidly developing bodies，可知年輕人為了強壯的身體應該多吃鈣和鐵．故選B．
52．D細節(jié)理解題．根據(jù)第四段As part of a television series，‘Jamie's School Dinners'，he worked with teachers and cooks in a number of schools across the UK to provide more healthy，nutritious school meal options．可知Jamie Oliver發(fā)起一項運動讓學校的老師教學生做營養(yǎng)食品，從而提高孩子們在學校的飲食．故選D．
53．C推理判斷題．根據(jù)最后一段No one expects to end the teenage love affair with fast and junk food but，可知作者認為年輕人偶而吃些垃圾食品沒有大礙．故選C．
點評 本文考察學生的理解推斷能力，抓住文章的關鍵詞，采用尋讀的方法查找細節(jié)，能根據(jù)已知的結果推測導致結果的可能原因．
