1.Since the first Earth Day in 1970,American have gotten a lot"greener"toward the environment."We didn't know at that time 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 affairs 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.
     According to US government reports,emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons.The number of cities producing CO beyond the standard has been reduced from 40 to 9.Although serious problems still remain and need to be dealt 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 1988 there were only 600 recycling programs; today in 1995 there are about 6,600.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 programs 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!"say Bruce Anderson.

分析 本文屬于說明文閱讀,作者在本文中把現(xiàn)在的美國(guó)環(huán)境問題和以前的環(huán)境問題進(jìn)行了比較,尤其是對(duì)比了幾項(xiàng)數(shù)據(jù).說明現(xiàn)在人們的環(huán)境保護(hù)意識(shí)有了很大的提高.其中很重要的一項(xiàng)就是環(huán)境教育所起的作用.

解答 25.C  細(xì)節(jié)理解題.根據(jù)文章第一段"We didn't know at that time there even was an environment,let alone that there was a problem with it,"says Bruce Anderson,president of Earth Day USA.可知在1970年世界地球日開始的時(shí)候,人們甚至都不知道有"環(huán)境"這個(gè)詞,更不要說知道存在著環(huán)境問題了.故選C.
26.A  細(xì)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 Americans are taking part in the movement.商務(wù)人士、政治領(lǐng)袖、大學(xué)教授,尤其是基層的數(shù)以百萬計(jì)的美國(guó)人都參加了運(yùn)動(dòng),可知環(huán)境保護(hù)的主要支持來自于普通民眾.故選A.
27.D  推理判斷題.根據(jù)第三段According to US government reports,emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons.The number of cities producing CO beyond the standard has been reduced from 40 to 9.可知通過人們的共同努力,現(xiàn)在的污染排放的數(shù)字已經(jīng)大大地減少了,故選D.
28.A  推理判斷題.根據(jù)文章最后一段Twenty-five years ago,there were hardly any education programs for environment.Today,it's hard to find a public school,university,or law school that does not have such a kind of program.可知現(xiàn)在幾乎每個(gè)學(xué)校都有關(guān)于環(huán)境保護(hù)方面的教育的內(nèi)容.說明教育在環(huán)境保護(hù)方面有很重要的作用.故選A.

點(diǎn)評(píng) 做閱讀理解時(shí)要快速的瀏覽全文,把握文章主旨大意,帶著問題回到原文,尋找細(xì)節(jié)或概括相應(yīng)的答案,最后要理清作者寫作思路.

2.Fear may be felt in the heart as well as in the head,according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.
Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting(收縮) and pumping blood around their bodies,compared with the point when the heartbeat is relaxed.Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful event,depending on which point it is at in its regular cycle of contraction and relaxation.
Sarah Garfinkel at the Brighton and Sussex Medical School said:"Our study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart."
The study tested 20healthy volunteers on their reactions to fear as they were shown pictures of fearful faces.Dr Garfinkel said,"The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed.Thus our hearts can also affect what we see and what we don't see-and guide whether we see fear."
To further understand this relationship,the scientists also used a brain scanner(掃描儀) to show how the brain influences the way the heart changes a person's feeling of fear.
"We have found an important mechanism by which the heart and brain‘speak'to each other to change our feelings and reduce fear,"Dr Garfinkel said.
"We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced,we may be able to develop more successful treatments for anxiety disorders,and also for those for those who may be suffering from serious stress disorder."
47.What is the finding of the study?A
A.One's heart affects how he feels fear.
B.fear is a result of one's relaxed heartbeat.
C.fear has something to do with one's health.
D.Ones fast heartbeats are likely to cause fear.
48.The study was carried out by analyzingC.
A.volunteers'heartbeats when they saw terrible pictures
B.the time volunteers saw fearful pictures and their health conditions
C.volunteers'reactions to horrible pictures and data form their brain scans
D.different pictures shown to volunteers and their heart-brain communication
49.Which of the following is closest in meaning to"mechanism"in Paragraph 6?B
A.Order.B.system.C.Machine.D.Treatment.
50.This study may contribute toA.
A.treating anxiety and stress better
B.explaining the cycle of fear and anxiety
C.finding the sky to the heart-brain communication
D.understanding different fears in our hearts and heads.

6.It was a Sunday and the heavy storm had lasted all night.The morning after the storm,though,was beautiful:blue skies,warm air and a calm,inviting sea touching the shore gently.
    My father realised it was a good day for fishing and invited my sister and me to go with him.I was only 14 and fishing had never been my thing,but I decided to go all the same.I'm so glad I did.
    On the road to the harbour we could see the terrible destruction on the coast,but the harbour itself was in fairly good shape.After all,it was protected by the arms of a bay that had only one tiny channel to the sea.As we got on board,we noticed two big humps (脊背) in the distance.
    On approaching them,we saw it was a mother whale with her baby.We couldn't believe it--there aren't any whales along the coast here.The storm must have driven them across the ocean into the bay,in which the still water was so badly polluted that nothing could survive.
    The little baby whale-actually as big as our boat-was obviously stuck and could not move.The mother dived under the water and came up suddenly,making big whirlpools (漩渦) and waves."She's trying to help her baby,but on the wrong side,"my father said.At this point,my father moved our boat in a semicircle to the other side and,heading the boat towards the baby whale,pushed it gently.With our several gentle pushes the big hump turned over and disappeared under water.Then it swam up right beside its mum.They struggled in their desperate attempts to escape but missed the exit and started heading in the wrong direction.We hurried up to the whales and tried to lead them towards the bay channel.Slowly,they let us lead them,sometimes rising from the water right beside us to breathe--and to give us a trusting look with those huge eyes.Once they hit their first part of clean water flowing straight from the sea,the mum gave us a wave with her tail and off they swam into the distance.
    In the excitement it had felt like only a few minutes,but we had been with those wonderful animals for almost an hour and a half.That was the simple and lasting beauty of the day.Nearly four decades later,I still look back fondly to that golden day at sea.

51.The author says"I'm so glad I did."(in Para.2)becauseC.
A.he witnessed the whole process of fishing
B.he enjoyed the beauty of the calm sea

A.the shape of the harbour
B.the arms of the bay
C.the still water in the channel
D.the long coast line

A.she had stayed in the polluted water for too long
B.the whirlpools she had made were not big enough
C.she had no other whales around to turn to for help
D.the waves pushed her baby in the wrong direction

13.If a diver surfaces too quickly,he may suffer the bends.Nitrogen(氮) dissolved(溶解) in his blood is suddenly liberated by the reduction of pressure.The consequence,if the bubbles (氣泡)accumulate in a joint,is sharp pain and abent body-thus the name.If the bubbles form in his lungs or his brain,the consequence can be death.
  Other air-breathing animals also suffer this decompression(減壓) sickness if they surface too fast:whales,for example.And so,long ago,did ichthyosaurs.That these ancient sea animals got the bends can be seen from their bones.If bubbles of nitrogen form inside the bone they can cut off its blood supply.This kills the cells in the bone,and consequently weakens it,sometimes to the point of collapse.Fossil (化石)bones that have caved in on them selves are thus a sign that the animal once had the bends.
  Bruce Rothschild of the University of Kansas knew all this when he began a study of ichthyosaur bones to find out how widespread the problem was in the past.What he particularly wanted to investigate was how ichthyosaurs adapted to the problem of decompression over the 150 million years.To this end,he and his colleagues traveled the world's natural-history museums,looking at hundreds of ichthyosaurs from the Triassic period and from the later Jurassic and Cretaceous periods.
When he started,he assumed that signs of the bends would be rarer in younger fossils,reflecting their gradual evolution of measures to deal with decompression.Instead,he was astonished to discover the opposite.More than 15% of Jurassic and Cretaceous ichthyosaurs had suffered the bends before they died,but not a single Triassic specimen(標(biāo)本) showed evidence of that sort of injury.
  If ichthyosaurs did evolve an anti-decompression means,they clearly did so quickly-and,most strangely,they lost it afterwards.But that is not what Dr Rothschild thinks happened.He suspects it was evolution in other animals that caused the change.
  Whales that suffer the bends often do so because they have surfaced to escape a predator (捕食動(dòng)物) such as a large shark.One of the features of Jurassic oceans was an abundance of large sharks and crocodiles,both of which were fond of ichthyosaur lunches.Triassic oceans,by contrast,were mercifully shark-and crocodile-free.In the Triassic,then,ichthyosaurs were top of the food chain.In the Jurassic and Cretaceous,they were prey(獵物) as well as predator-and often had to make a speedy exit as a result.

61.Which of the following is a typical symptom of the bends?A
A.A twisted body.
B.A gradual decrease in blood supply.
C.A sudden release of nitrogen in blood.
D.A drop in blood pressure.
62.The purpose of Rothschild's study is to seeB.
A.how often ichthyosaurs caught the bends    
B.how ichthyosaurs adapted to decompression
C.why ichthyosaurs bent their bodies      
D.when ichthyosaurs broke their bones
63.Rothschild'sfindingstatedinParagraph4C.
A.confirmed his assumption     
B.speeded up his research process
C.disagreed with his assumption                         
D.changed his research objectives
64.Rothschild might have concluded that ichthyosaursA.
A.failed to evolve an anti decompression means    
B.gradually developed measures against the bends
C.died out because of large sharks and crocodiles  
D.evolved an anti decompression means but soon lost it.

10.Kids'health:Four steps for fighting stress
Everybody gets stressed from time to time.(71)CSome ways of dealing with stress-like screaming or hitting someone-don't solve(解決)much.But other ways,like talking to someone you trust,can lead you to solving your problem or at least feeling better.Try taking these four steps the next time you are stressed:
(1)Get support.When you need help,reach out to the people who care about you.Talk to a trusted adult,such as a parent or other relatives.(72)FThey might have had similar problems,such as dealing with a test,or the death of a beloved pet.
(2)Don't take it out on yourself.Sometimes when kids are stressed and upset they take it out on themselves.Oh,dear,that's not a good idea.Remember that there are always people to help you.Don't take it out on yourself.(73)A
(3)Try to solve the problem.After you're calm and you have support from adults and friends,it's time to get down to business.(74)EEven if you can't solve it all,you can solve a piece of it.
(4)Be positive.Most stress is temporary (暫時(shí)的).Remember stress does go away,especially when you figure out the problem and start working on solving it.
These steps aren't magic,but they do work.And if you can stay positive as you make
(5)your way through a tough time,you'll help yourself feel better even faster.(75)D

A.Ask for a helping hand to get you through the tough situation.
B.Notice your friends'feelings and find a way to help them.
C.Different people feel stress in different ways.
D.Ah,it feels so good when the stress is gone.
E.You need to figure out what the problem is.
F.And don't forget about your friends.
G.Then,find a way to calm down.
