3.Since the first Earth Day in 1970,Americans have gotten a lot"greener"toward the environment."We didn't know at that time that there even was an environment,let alone that there was a problem with it,"says Bruce Anderson,president of Earth Day USA.
But what began as nothing important in public affaris has grown into a social movement.Business people,political leaders,university professors,and especially millions of grass-roots Americans are taking part in the movement."The understanding has increased many,many times,"says Gaylord Nelson,the former governor from Wisconsin,who thought up the first Earth Day.
According to US government reports,emissions(排放)from cars and trucks have dropped from 10.3million tons a year to 5.5million tons.The number of cities producing CO beyond the standard has been reduced from 40to 9.Although serious problems still remain and need to be dealth with,the world is a safer and healthier place.A kind of"green thinking"has become part of practices.
Great improvement has been achieved.In 1988there were only 600recycling programs; today in 1995there are about 6600.Advanced lights,motors,and building designs have helped save a lot of energy and therefore prevented pollution.
Twenty-five years ago,there were hardly any education programms for environment.Today,it's hard to find a public school,university,or law school that does not have such a kind of program.Until we do that,nothing else will change!"says Bruce Anderson.

25.According to Anderson,before 1970,Americans had little idea aboutC.
A.the social movement                  B.recycling techniques
C.environmental problems               D.the importance of Earth Day
26.Where does the support for environmental protection mainly come from?A
A.The grass-roots level.B.The business circle.
C.Government officials.D.University professors.
27.What have Americans achieved in environmental protection?D
A.They have cut car emissions to the lowest.
B.They have settled their environmental problems.
C.They have lowered their CO levels in forty cities.
D.They have reduced pollution through effective measures.

分析 本文是一篇記敘文.本文介紹了自從1970年第一個地球日成立以來,美國的環(huán)境問題有了很大的改善.以前在公共事物中無足輕重的環(huán)境問題現(xiàn)在成了一項社會關(guān)注的問題,從科學(xué)家到大學(xué)教授到貧民百姓都有了環(huán)保意識.

解答 答案:25-27 CAD
25:C.細節(jié)理解題.根據(jù)文章首段Anderson說的話"We didn't know at that time there even was an environment,let alone that there was a problem with it,可知當(dāng)時人們不知道環(huán)境這個概念,更別說環(huán)境問題了,故C選項正確.
26:A.細節(jié)理解題.根據(jù)文章第二段.Business people,political leaders,university professors,and especially millions of grass-roots可知商人,政界領(lǐng)導(dǎo),大學(xué)教授,尤其是平民百姓們都參與到了保護環(huán)境的運動中來,由此判斷保護環(huán)境的支持主要來自草根階層,故A選項正確.
27:D.細節(jié)理解題.根據(jù)文章倒數(shù)第二段內(nèi)容In 1988 there were only 600 recycling programs …and building designs have helped save a lot of energy and therefore prevented pollution.可知,回收工作的改進,先進產(chǎn)品和住房設(shè)計的研制開發(fā)等措施都有效地減少了污染,改善了環(huán)境,故D選項正確.

點評 閱讀理解考查對文章的理解能力,細節(jié)理解題是常見題型,應(yīng)注意選項與原文相符,切莫張冠李戴,以偏概全.

14.Doctors say anger can be an extremely damaging emotion,unless you learn how to deal with it.They warn that anger can lead to heart disease,stomach problems,headaches,emotional problems and possibly cancer.
(31)F Some people express anger openly in a calm reasonable way.Others burst with anger,and scream and yell.But other people keep their anger inside.They can not or will not express it.This is called repressing anger.
For years many doctors thought that repressing anger was more dangerous to a person's health than expressing it.They said that when a person is angry,the brain releases the same hormones (荷爾蒙).They speed the heart rate,raise blood pressure,or sugar into the blood,etc.(32)A
Some doctors say that both repressing and expressing anger can be dangerous.They believe that those who express anger violently may be more likely to develop heart disease,and they believe that those who keep anger inside may face a greater danger of high blood pressure.
(33)G They say the first step is to admit that you are angry and to recognize the real cause of the anger,then decide if the cause is serious enough to get angry about.If it is,they say,"(34)E Wait until your anger has cooled down and you are able to express yourself calmly and reasonably."
Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry.(35)B

A.In general the person feels excited and ready to act.
B.They said that laughter is much healthier than anger.
C.Expressing anger violently is more harmful than repressing it.
D.Anger may cause you a cancer.
E.Do not express your anger while angry.
F.Anger is a normal emotion that we all feel from time to time.
G.Doctors say the solution is learning how to deal with anger.

about my situation.He encouraged me to speak out that I wanted to speak.Whenever I
made mistakes and felt discouraging,my teacher and classmates will help me find out
how I could avoid it in the future.Practice makes perfect.With time went by,I built up  my confidences,and now I can talk fluently in English.Just as sa ying goes,mistakes are where success lies.We just need to learn a lesson from the mistakes.

13.Guide dogs are going to be available for the children who are unable to see normally in the UK for the first time,as the age limit is to be removed.The Guide Dogs for the Blind Association is to begin training dogs to help blind people under the age of 16.
The association says too many youngsters with impaired eyesight are lacking in independence.They have only a limited social life because of their disability.Giving some of them guide dogs at a younger age is intended to help them to widen their range of activities and to improve their sense of self-confidence and independence.Guide dogs for these teenagers will begin to be provided from next year.There has been an experimental project to test the use of guide dogs with younger people.
Charlotte,aged 14,was among the youngest guide dog owners.She had been gradually losing her eyesight since the age of eight,and lost her eyesight completely this year.She has been assisted by a two-year-old guide dog.Charlotte used to have a long stick to help her move around,but having a guide dog allows her much more freedom and makes her feel safer.
However,the association says there is a worryingly patchy supply of services for the young blind people across the UK,and it calls for national standards to be introduced.As with adult blind people,only a small number of them are likely to be considered suitable for a guide dog.Most will continue to rely on extra help and training from education and social services.

29.We can learn from the text that owning guide dogsA.
A.is beneficial to blind children's development
B.may meet with difficulties sometimes
C.became possible in the UK recently
D.is quite universal in the UK
30.According to the text,Charlotte's example proves thatC.
A.the association's opinion is not quite right
B.guide dogs can get along well with disabled people
C.it is necessary to carry out the experimental project
D.youngsters need companions and friends
31.What does the underlined word"patchy"in the last paragraph probably mean?D
A.Endless.      
B.Perfect.
C.Diverse.        
D.Inadequate.
32.What is the main idea of the text?B
A.Blind people need guide dogs'assistance in their daily life.
B.Age limit for the blind to have guide dogs is to be removed.
C.More guide dogs will be trained in the UK.
D.The project of using guide dogs is to begin.
