4.The spread of Western eating habits around the world is bad for human health and for the environment.Those findings come from a new report in the journal Nature.
David Tilman is a professor at the University of Minnesota.In the study,he examined information from 100nations to show what people ate and how diet affected health.Mr.Tilman noted a movement beginning in the 1960s.He found that as nations industrialized(工業(yè)化),population increased and earnings rose.More people began to adopt what has been called the Western diet.The Western diet is high in sugar,fat,oil and meat.By eating these foods,people began to get fatter and sicker.
"The food,let us say,in the 15 richest nations of the world,right now contains about 400or 500extra calories(熱量) a day that are eaten beyond what people need,and that leads people to gain weight."
David Tillman says overweight people are at greater risk for diseases like diabetes,heart disease and some cancers.Diabetes is shooting to very high rates in the United States and across Europe.Heart disease is a major cause of death in the Western nations.Unfortunately when people become industrialized,if they adopt this Western diet,they are going to have these same health problems.
A diet bad for human beings,it seems,is also bad for the environment.As the world's population grows,experts say more forests and areas will become farmland for crops or grasslands for raising cattle.These areas will be needed to meet the increasing demand for food.
Mr.Tilman calls the link between diet,the environment and human health,"a dilemma",a situation where it is very difficult to decide what to do.He says one possible solution is leaving the Western diet behind.

53.Why did people get fatter in the 1960s?A.
A.They ate foods high in calories.
B.They adopted a western lifestyle.
C.They set aside little time for exercise.
D.They had a better life and became lazier.
54.According to the text,overweight people may suffer the following diseases EXCEPTB.
A.diabetes
B.skin disease
C.cancers
D.heart disease
55.What is the purpose of the author in writing this passage?B.
A.To tell people effective ways to keep healthy.
B.To call on people to give up the Western diet.
C.To show the problems industrialized nations are facing.
D.To draw people's attention to environmental protection.

分析 本文主要講述了隨著全球化進程進一步加快,西方的飲食習慣也層層逼近世界的每一個角落,它是否對我們的飲食健康或者環(huán)境造成影響呢?這篇文章就做了詳細的介紹.

解答 53.A.細節(jié)理解題.根據(jù)第二段:The Western diet is high in sugar,fat,oil and meat.By eating these foods,people began to get fatter and sicker可知20世紀60年代的人們吃高熱量的食物導致他們變胖;故選A.
54.B.細節(jié)理解題.根據(jù)第四段:David Tillman says overweight people are at greater risk for diseases like diabetes,heart disease and some cancers可知超重的人可能患有糖尿病,癌癥和心臟。恢挥蠦沒有提到,故選B.
55.B.寫作意圖題.綜合全文,尤其是根據(jù)文章最后一段的最后一句可知,西方飲食有害健康,不利于環(huán)境,故作者是想通過該文讓人們警惕西方飲食帶來的危害,讓讀者放棄西方飲食;故選B.

點評 本文是人物故事類閱讀理解.做這類題材閱讀理解時要求考生對文章通讀一遍,做題時結合原文和題目有針對性的找出相關語句進行仔細分析,結合選項選出正確答案.推理判斷題也是要在抓住關鍵句子的基礎上合理的分析才能得出正確答案,切忌胡亂猜測,一定要做到有理有據(jù)

9.Papa,as a son of a dirt-poor farmer,left school early and went to work in a factory,for education was for the rich then.So,the world became his school.With great interest,he read everything he could lay his hands on,listened to the town elders and learned about the world beyond his tiny hometown."There's so much to learn,"he'd say."Though we're born stupid,only the stupid remain that way."He was determined that none of his children would be denied (拒絕) an education.
Thus,Papa insisted that we learn at least one new thing each day.Though,as children,we thought this was crazy,it would never have occurred to us to deny Papa a request.And dinner time seemed perfect for sharing what we had learned.We would talk about the news of the day; no matter how insignificant, it was never taken lightly.Papa would listen carefully and was ready with some comment,always to the point.
Then came the moment-the time to share the day's new learning.
Papa,at the head of the table,would push back his chair and pour a glass of red wine,ready to listen.
"Felice,"he'd say,"tell me what you learned today."
"I learned that the population of Nepal is…"
Silence.
Papa was thinking about what was said,as if the salvation(拯救)of the world would depend upon it."The population of Nepal.Hmm.Well…"he'd say."Get the map; let's see where Nepal is."And the whole family went on a search for Nepal.
This same experience was repeated until each family member had a turn.Dinner ended only after we had a clear understanding of at least half a dozen such facts.
As children,we thought very little about these educational wonders.Our family,however,was growing together,sharing experiences and participating in one another's education.And by looking at us,listening to us,respecting our input,affirming (肯定) our value,giving us a sense of dignity,Papa was unquestionably our most influential teacher.
Later during my training as a future teacher,I studied with some of the most famous educators.They were imparting what Papa had known all along-the value of continual learning.His technique has served me well all my life.Not a single day has been wasted,though I can never tell when knowing the population of Nepal might prove useful.

24.What do we know from the first paragraph?C
A.The author's father was born in a worker's family.
B.Those born stupid could not change their life.
C.The poor could hardly afford school education.
D.The town elders wanted to learn about the world.
25.The underlined word"it"in the second paragraph refers to"B
A.one new thing  
B.the news  
C.a(chǎn) request  
D.some comment
26.What is the greatest value of"dinner time"to the author?C
A.Winning Papa's approval.
B.Showing talents.
C.Continual learning.
D.Family get-together.
27.It can be learned from the passage that the authorA.
A.a(chǎn)ppreciated his father's educational technique 
B.knew very well about Nepal
C.felt regret about those wasted days

13.From the health point of view we are living in an amazing age.We are free from  many of the most dangerous diseases.A large number of once deadly illnesses can now be cured by modern medicine.It is almost certain that one day medicines will be found for the most stubborn remaining diseases.The expectation of life has increased greatly.But though the possibility of living a long and happy life is greater than ever before,every day we witness the unbelievable killing of men,women and children on the roads.Man vs the motor-car.It is a never-ending battle which man is losing.Thousands of people the world over are killed or horribly killed each year and we are quietly sitting back and letting it happen.
   It has been rightly said that when a man is sitting behind a steering wheel(方向盤),his car becomes the extension of his personality.There is no doubt that the motor-car often brings out a man's very worst qualities.People who are normally quiet and pleasant may become unrecognizable when they are behind a steering-wheel.They say,they are ill-mannered and aggressive,willful as two-years-olds and completely selfish.All their hidden angers and disappointments seem to be brought to the surface by the act of driving.
   The surprising thing is that society smiles so gentlly on the motorist and seems to forgive his behavior.Everything is done for his convenience.Cities are allowed to become almost uninhabitable because of heavy traffic; towns are made ugly by huge car parks; the countryside is ruined by road networks; and the deaths become nothing more than a number every year,to be easily forgotten.
   It is high time a world rule was created to reduce this senseless waste of human life.With regard to driving,the laws of some countries are unbelievably lax(不嚴格) and even the strictest are not strict enough.A rule which was universally accepted could only have an obviously beneficial effect on the accident rate.Here are a few examples of some of the things that might be done.The driving test should be standardlized and made far more difficult than it is; all the drivers should be made to take a test every three years or so; the age at which young people are allowed to drive any vehicle should be raised to at least 21; all vehicles should be put through strict tests for safety each year.Even the smallest amount of alcohol in the blood can damage a person's driving ability.Present drinking and driving laws (where they exist) should be made much stricter. Speed limits should be required on all roads.Governments should lay down safety specifications for car factories,as has been done in the USA.All advertising stressing power and performance should be banned.These measures may not sound good enough.But surely nothing should be considered as too severe if it results in reducing the number of deaths.After all,the world is for human beings,not motor-cars.

51.What is the main idea of this passage?C
A.Traffic accidents are mainly caused by motorists.
B.Thousands of people the world over are killed each year.
C.Only stricter traffic laws can prevent accidents.
D.The laws of some countries about driving are too lax.
52.What does the author think of society toward motorists?B
A.Society laughs at the motorists.
B.Society forgives their rude driving.
C.Victims of accidents are nothing.
D.Huge car parks are built in the cities and towns.
53.What does the author say"his car becomes the extension of his personality"in Para.2?D
A.Driving can represent his manners.
B.Driving can show the other part of his personality.
C.Driving can bring out his character.
D.Driving can show his hidden qualities.
54.Which of the followings is NOT mentioned as a way against traffic accidents?A
A.Build more highways.
B.Stricter driving tests.
C.Test drivers every three years
D.Raise age limit and lay down safety specifications.
55.The author's attitude towards the present traffic situation isA
A.unsatisfied
B.positive
C.a(chǎn)ppealing
D.unclear.
