8.A rapidly advancing contemporary science that is highly dependent on new tools is Earth system science.Earth system science involves observation and measurements on the Earth at all scales from the largest to the smallest.The huge amounts of data that are gathered come from many different locations and require special techniques for handling data.Important new tools that facilitate Earth system science include satellite remote sensing,small deep-sea submarines,and geographic information systems.
More than any other way of gathering evidence,satellite observations continually remind us that each part of the Earth interacts with and is dependent on all other parts.
Earth system science was born from the realization of that interdependence.Satellite remote sensing makes possible observations at large scales,and in many cases,measurements of factors that could not otherwise be measured.For example,the ozone hole over Antarctica--the decrease in the concentration of ozone high in the atmosphere--is measured by remote sensing,as are changes in deserts,forests,and farmlands around the world.Such measurements can be used in many areas of specialization besides Earth system science.Archaeology,for example,has benefited from satellite observations that reveal the traces of ancient trade routes across the Arabian Desert.
New tools for exploring previously inaccessible areas of the Earth have also added greatly to our knowledge of the Earth system.Small deep-sea submarines allow scientists to travel to the depths of the ocean.There they have discovered new species and ecosystems thriving near deep-sea vents that emit heat,sasses,and mineral-rich water.
Just as important as new methods of measurement and exploration are new ways to store and analyze data about the Earth system.Computer-based software programs known as geographic information systems,or GIS,allow a large number of data points to be stored along with their locations.These can be used to produce maps and to compare different sets of information gathered at different times.For example,satellite remote sensing images of a forest can be converted to represent stages in the forest's growth.Two such images,made at different times can be overlaid and compared,and the changes that have taken place can be represented in a new image.

15.A policeman is questioning 3blondes (金发女人) who are training to become detectives.To test their skills in recognizing a suspect (嫌疑犯).He shows the first blonde a picture for 5seconds and then hides it.
"This is your suspect.How would you recognize him?"
The first blonde answers,"That's easy.We'll catch him fast because he only has one eye!"The policeman says,"Well…uh…that's because the picture shows his profile (侧面轮廓)."
Slightly confused by this ridiculous response,he flashes the picture for 5seconds at the second blonde and asks her,"This is your suspect.How would you recognize him?"
The second blonde giggles,flips her hair and says,"Ha!He'd be too easy to catch because he only has one ear!"
The policeman angrily responds,"What's the matter with you two?Of course only one eye and one ear are showing because it's a picture of his profile!Is that the best answer you can come up with?"
Extremely frustrated at this point,he shows the picture to the third blonde and in a very testy voice asks,"This is your suspect.How would you recognize him?"He quickly adds,"Think hard before giving me a stupid answer."
The blonde looks at the picture intently for a moment and says,"Hmm…the suspect wears contact lenses (隐形眼镜)."
The policeman is surprised and speechless because he really doesn't know himself if the suspect wears contacts or not."Well,that's an interesting answer…Wait here for a few minutes while I check his file and I'll get back to you on that."He leaves the room and goes to his office,checks the suspect's file in his computer,and comes back with a beaming smile on his face."Wow!I can't believe it…it's true!The suspect does in fact wear contact lenses.Good work!How were you able to make such an acute observation?"
"That's easy,"the blonde replies."He can't wear regular glasses because he only has one eye and one ear."

51.Why does the policeman show a picture to the three blondes?C.

5.Until late in the 20th century,most Americans spent time with people of generations.Now mid-aged Americans may not keep in touch with old people until they are old themselves.That's because we group people by age.We put our three-year-olds together in day-care center,our 13-year-olds in school and sports activities,and our 80-year-olds in senior-citizen homes.Why?
We live away from the old for many reasons:young people sometimes avoid the old to get rid of fears for aging and dying.It is much harder to watch.someone we love disappear before our eyes.Sometimes it's so hard that we stay away from the people who need us most.
Fortunately,.some of us have found our way to the old.And we have discovered that they often save the young.
A reporter moved her family onto a block filled with old people.At first her children were disappointed.But the reporter baked banana bread for the neighbours and had her children deliver it and visit.Soon the children had many new friends,with whom they shared food,stories and projects."My children have never been less lonely,"the reporter said.
The young,in turn,save the old.Once I was in a rest home when a visitor showed up with a baby.She was immediately surrounded.People who hadn't gotten out of bed in a week suddenly were ringing for a wheelchair.Even those who had seemed asleep wake up to watch the child.Babies have an astonishing power to comfort and cure.
Grandparents are a special case.They give grandchildren a feeling of security and continuity.As my husband put it,"my grandparents gave me a deep sense that things would turn out right in the end."
Grandchildren speak of attention they don't get from worried parents."My parents were always telling me to hurry up,and my grandparents told me to slow down,"one friend said.A teacher told me she can tell which pupils have relationships with grandparents:they are quieter,calmer,more trusting.

29.Now in an American family,people can find thatC.
A.children never live with their parents.
B.aged people are supported by their grandchildren.
C.not all working people live with their parents.
D.grandchildren are supported by their grandparents.
30.The reason why old people are left alone may be thatD.
A.the old don't like to live in a big family.
B.the young can't get enough money to support the old.
C.the old are too weak to live with the young.
D.different generations have different lifestyles.
31.The fact that the reporter told us shows thatA.
A.old people are easy to get along with.
B.old people in America enjoy banana bread.
C.she had no time to take care of her children.
D.old people in America lead a hard life.
32.By saying"Babies have an astonishing power to comfort and cure"the author meansC.
A.old people had never seen her baby before
B.the baby was clever and beautiful
C.the baby brought old people the image of life
D.the baby's mother would take care of them.
12.You are given many opportunities in life to choose to be a victim or creator.When you choose to be a victim,the world is a cold and difficult place."They"did things to you which caused all of your pain and suffering."They"are wrong and bad,and life is terrible as long as"they"are around.Or you may blame yourself for all your problems,thus internalizing(内化)your victimization.The truth is,your life is likely to stay that way as long as you feel a need to blame yourself or others.
Those who choose to be creators look at life quite differently.They know there are individuals who might like to control their lives,but they don't let this get in the way.They know they have their weaknesses,yet they don't blame themselves when they fail.Whatever happens,they have choice in the matter.They believe their dance with each sacred(神圣的)moment of life is a gift and that storms are a natural part of life which can bring the rain needed for emotional and spiritual growth.
Victims and creators live in the same physical world and deal with many of the same physical realities,yet their experience of life is worlds apart.Victims relish (沉溺)in anger,guilt,and other emotions that cause others---and even themselves---to feel like victims,too.Creators consciously choose love,inspiration,and other qualities which inspire not only themselves,but all around them.Both victims ad creators always have choice to determine the direction of their lives.
In reality,all of us play the victim or the creator at various points in our lives.One person,on losing a job or a special relationship,may feel as if it is the end of the world and sink into terrible suffering for months,years,or even a lifetime.Another with the same experience may choose to first experience the grief,then accept the loss and soon move on to be a powerful creative force in his life.
In every moment and every circumstance,you can choose to have fuller,richer life by setting a clear intention to transform the victim within,and by inviting into your life the powerful creator that you are.

9.Getting kids to share their toys is a never-ending battle,and forcing them to do so never seems to help.New research suggests that allowing children to make a choice to sacrifice their own toys in order to share with someone else makes them share more in the future.The new findings are published in Psychological Science.
These experiments were conducted by psychological scientists,Nadia Chernyak and Tamar Kushnir of Cornell University.They found that sharing things with others when they are given a difficult choice leads children to think of themselves as people who like to share.It also makes them more likely to act in a pro-social (亲社会的)manner in the future.
Previous research has explained why rewarding children for sharing can backfire.Children come to think of themselves as people who don't like to share since they had to be rewarded for doing so.Because they don't view themselves as"sharers"they are less likely to share in the future.
Chernyak and Kushnir were interested in finding out whether freely chosen sacrifice might have the opposite effect on kids'willingness to share.To test this,the researchers introduced five-year-old children to Doggie,a sad puppet.Some of the children were given a difficult choice:Share a precious sticker with Doggie,or keep it for themselves.Other children were given an easy choice between sharing and putting the sticker away,while children in a third group were required by the researcher to share.
Later on,all the children were introduced to Ellie,another sad puppet.They were given the option of how many stickers to share (up to three).The kids who earlier made the difficult choice to help Doggie shared more stickers with Ellie.The children who were initially faced with an easy choice or who were required to give their sticker to Doggie,on the other hand,shared fewer stickers with Ellie.Therefore,children did not benefit from simply giving something up,but rather from willingly choosing to give something up of value.
"You might imagine that making difficult,costly choices is taxing for young children or even that once children share,they don't feel the need to do so again,"Chernyak says."But this wasn't the case:once children made a difficult decision to give up something for someone else,they were more generous,not less,later on."Chernyak concludes.
74.Dhelps children to share more in the future.
A.Rewarding children for sharing stickers
B.Requiring children to share their favorite toys
C.Allowing children to share what they don't need
D.Encouraging children to share precious things willingly
75.The underlined word"backfire"meansD.
A.serve as a push                  B.have an opposite effect
C.cause anger                      D.avoid taking things back
76.Those who were required to share give fewer stickers to Ellie becauseA.
A.it's not their own choice           B.they regret what they did
C.Ellie is not as sad as Doggie        D.they like to share with a real person
77.We can conclude from the passage thatC
A.parents will never find a way to get children to share toys
B.a gift should be given to make up for children's sacrifice
C.making difficult choices may influence sharing behavior
D.children pretend to be generous when they are being observed.
10.Shi Jianfei is a college student at Beijing Information Science and Technology University.He met with an academic problem during the summer vocation but it took him a lot determination to finally approach his professor to solve the problem.To his surprise,the meeting turned out to be quite pleasant.
But only few students turn to their professors to ask for advice in solving problems or discuss academic topics with them.According to an investigation of 2,636college students conducted by MyCOS,a Beijing-based consultancy (咨询公司),more than a third of them contact their,professor less than once a year.
Although most students and teachers are willing to communicate with each other,it seems that an effective communication system is absent.Shi says,"Communication usually takes place in class or between classes,because it's difficult to get in touch with professors at any other time.University professors always look very busy."
However,from the teachers'perspective,students are too cautious about communicating with professors."They're worried about asking questions for they think they may leave a bad impression,"says Du Xiguang,professor of chemistry at Northeast Normal University.Du created a QQ group in which students can discuss various issues with him,ranging from academic topics to personal problems."I find they are very talkative in this group.But if they talk to me in person,they're shy and nervous,"he says.
Wu Qian,22,an English major at Tsinghua University admits that when she meets with  problems she prefers talking to her classmates and upper-classmen."I think many students are too shy and passive,myself included.I feel more comfortable communicating with my classmates,"she says.
Du also says that the shyness of many students to a change lies in different teaching styles.In primary school,Chinese students get used to talking with their teachers because they're like"nannies"who not only teach,but also watch out for their students'personal development.
"In college,such communication isn't compulsory any more and students aren't pushed to discuss their ideas with professors,"says Du."The real problem is that students aren't yet ready to engage in adult conversation with professors.Some of them just expect professors to explain facts and help them prepare for exams,like in high school."

55.What does Paragraph 2talk about?B
A.The reason why the communication is little.
B.The present situation of communication.
C.The background of the phenomenon.
D.The details of the phenomenon.
56.What's the real reason why Shi Jianfei didn't turn to his professor for help immediately meeting with an academic problem?C
A.An effective communication mechanism is absent.
B.It's difficult to get in touch with professor.
C.He is too shy and passive.
D.Communication isn't compulsory any more.
57.The underlined word"nannies"is closest in meaning toA.
A.nurses         B.gardeners         C.friends          D.leaders
58.In which way does the author present the passage?D
A.By giving some dialogues between students and teachers
B.By giving some specific examples of students and teachers
C.By interviewing different students and teachers
D.By listing some facts and opinions of students and teachers.
