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.The word "facilitate" in Paragraph I is closest in meaning to ________.

| A.indications of ancient routes |
| B.evidence of former lakes |
| C.traces of early farms |
| D.remains of ancient forests |
What is the main idea of the passage?
| A.special techniques are needed to classify the huge amounts of data about Earth. |

As public playgrounds grow increasingly worn and shabby, the for-profit centers offer clean, safe, supervised activity as well as a variety of challenging exercises to develop youngsters’ physical fitness, usually for a fee of around $5 an hour. “Playgrounds are dirty, not supervised,” says Dick Guggenheimer, owner of the two-month-old Discovery Zone in Yonkers, N.Y., part of a Kansas City-based chain. “We’re indoors; we’re padded(铺上软垫); parents can feel their child is safe.”
Discovery Zone has sold 120 outlets in the past 14 months, boasting sandboxes full of brightly colored plastic balls, mazes(迷宫), obstacle courses, slides and mountains to climb. Now McDonalds is getting into the act. The burger giant is test-marketing a new playground, Leaps&Bounds, in Naperville, Ill. Phys Kids of Wichita has opened one center and has plans to expand.
American parents are rightly worried about their kids leisure life. There are 36 million children in the U.S. aged 2 to 11 who watch an average of 24 hours of TV a week and devote less and less energy to active recreation. Nationwide decrease in education budgets are making the problem worse, as gym classes and after-hours sports time get squeezed. Says Discovery Zone president Jack Gunion: “we have raised a couple of pure couch potatoes.”
In an attempt to attract more people , the new facilities cater to the concerns of two-earner families, staying open in the evenings, long after traditional public playground have grown dark and unusable. At Naperville’s Leaps&Bounds, families can play together for $4.95 per child, parents free. Fresh-faced assistants, dressed in colorful sport pants and shirts, guide youngsters to appropriate play areas for differing age group.
These new playground are not meant to be day-care facilities; parents are expected to stay and play with their kids rather than drop them off. But several also provide high-tech baby-sitting services. At some of the Discovery Zones, parents can register their children in special supervised programs, then leave them and slip away for a couple of hours to enjoy a movie or dinner.
The most fun of all, though, is getting to do what parents used to do in the days before two-career families and two-hour commutes: play with their kid. That, at least, is old-fashioned, even at per-hour rates.
68. What is this article mainly talking about?
A. Children can play in the public playground without parents’ care.
B. The fast development of Discovery Zone.
C. A new type of playground for kids.
D. The decay of outdoor playground.
69. According to the article, which of the following is true to the new playground?
A. The cost is high for a family.
B. It’s a place where kids can watch TV while eating potatoes.
C. It doesn’t allow parents to leave their kids.
D. It’s a place where parents can play together with their kids.
70. What does the writer mean by saying “old-fashioned”?
A. The so-called new playground is outdated.
B. the new playground offers a fashion which is popular in the past.
C. The new playground is also enjoyed by old people.
D. The new playground is actually enjoyed by parents
71. What is the writer’s attitude toward the new playground?
A. Agreeable. B. Indifferent. C. Objective. D. Neutral.

Not even Dan Brown and his Da Vinci code—breakers(密码破译者)dared deal with the mystery of Mona Lisa,s smile.But Nicu Sebe,a computer expert the University of Amsterdam,the Netherlands,did.He used’emotion recognition’software to process the famous painting and found Mona Lisa happy(83 per cent)and slightly disgusted(厌烦的)(9 per cent).
Faces show emotions. Psychology,computer science,and engineering researchers are joining forces to teach machines to read expressions.If they succeed,your computer may one day“read”your mood.Machines equipped with emotional skills could also be used in teaching,gaming,mind-reading,etc.
“Mind Reader”,a system developed by Rosalind Picard at MIT(the Massachusetts Institute of Tech’nology)in the US, uses input from a video camera to do real—time analysis of facial expressions. It reports on whether you seem“interested”or“agreeable”or if you’re“confused”.The system can help people recognize others’emotions.Picard says this means we could teach a machine to be as sensitive as a human.In fact,a machine can be even smarter than people since it can tell if a person is lying or just“performing”by analyzing one’s facial movements.
Jeffrey Cohn,a psychologist at the University of Pittsburgh,uses the Facial Action Coding System to recognize human emotions.The system sorts more than 40 action units(AUs)of the face to tell people’s real emotions.He studied a videotape of a criminal who said to be sad about the murder of several family members and tried to pin the blame on someone else.But Cohn saw no real sadness in the woman’s face.
Sadness is a group of AUs that is difficult to do at the same time.You have to pull down the woman’s of your lips while bringing your eyebrows together and raising them.What the woman did was raise her cheeks to make a lip cud(撇嘴)。Her brows stayed smooth.
64.The best title of this passage is“ ________ ”.
A.The emotion on your faceB.Look at your face
C.Your face tells a story D.Telling a lie
65.The missing sentence“This means,even though your mouth lice,your face doesn’t,and the machine will know it all. ”should be put at the end of ___________.
A.Paragraph 2 B.Paragraph 3C.Paragraph 4 D.Paragraph 5
66.How many facial emotion analyses are mentioned in this passage?
A.Four. B.Three. C.Two. D.One
67.The underlined word“it”refers to________.
A.MIT B.the video camera
C.one’s face emotion D.the real—time analysis

Lions are opportunists. They prefer to eat without having to do too much work. When resting in the shade, they are also watching the sky to see what is flying by, and even in the heat of the day they will suddenly start up and run a mile across the plains to find out what is going on. If another animal has made a kill, they will drive it off and take the dill for themselves. A grown lion can easily eat 60 pounds of meat at a single feeding. Often they eat until it seems painful for them to lie down.
The lioneases (母狮) , being thinner and faster, are better hunters (猎手) than the males (雄狮). But the males don’t mind. After the kill they move in and take the test share.
Most kills are made at night or just before daybreak. We have seen many, many daylight attempts but only ten kills. Roughly, It’s about twenty daytime attempts for one kill.
When lions are hiding for an attack by a water hole, they wait patiently and can charge at any second. The kill is the exciting moment in the day-to-day life of the lion, since these great animals spend most of their time, about 20 hours a day, sleeping and resting.
Lions are social cats, and when they are having a rest, they love to touch each other. After drinking at a water hole, a lioness rests her head on another’s back. When walking, young lions often touch faces with older ones, an act of close ties imong members of the group.
60. By describing lions as “opportunists” in the first paragraph, the author means to say that lions_____.
A. are cruel animals B. are clever animals
C. like to take advantage of other animals D. like to take every chance to eat
61. According to the text, which of the following is true?
A. Lions make most kills in the daytime.
B. Males care more about eating than active killing.
C. Lions are curious about things happening around them.
D. It doesn’t take lions too much time to make a kill.
62. How can we know that lions are social animals?
A. They depend on each other. B. They look after each other well.
C. They readily share what they have. D. They enjoy each other’s company.
63. What would be the best tiltle for the text?
A. Powerful Lions B. Lions at Work and Play
C. Lions, Social Cats D. Lions, Skilled Hunters

Reading poems is not exactly an everyday activity for most people. In fact, many people never read a poem once they get out of high school.
It is worth reminding ourselves that this has not always been the case in America. In the nineteenth century, a usual American activity was to sit around the fireside in the evening and read poems aloud. It is true that there was no television at the time, nor movie theaters, nor World Wide Web, to provide diversion. However, poems were a source of pleasure, of self-education, of connection to other people or to the world beyond one’s own community. Reading them was a social act as well as an individual one, and perhaps even more social than individual. Writing poems to share with friends and relations was, like reading poems by the fireside, another way in which poetry has a place in everyday life.
How did things change? Why are most Americans no longer comfortable with poetry, and why do most people today think that a poem has nothing to tell them and that they can do well without poems?
There are, I believe, three culprits(肇事者):poets, teachers, and we ourselves. Of these, the least important is the third: the world surrounding the poem has betrayed us more than we have betrayed the poem. Early in the twentieth century, poetry in English headed into directions unfavorable to the reading of poetry. Readers decided that poems were not for the fireside or the easy chair at night, that they belonged where other difficult-to-read things belonged.
Poets failed the readers, so did teachers. They want their students to know something about the skills of a poem, they want their students to see that poems mean something. Yet what usually occurs when teachers push these concerns on their high school students is that young people decide poems are unpleasant crossword puzzles.
56.Reading poems is thought to be a social act in the nineteenth century because___________.
A.it built a link among people B.it helped unite a community
C.it was a source of self-educationD.it was a source of pleasure
57. The underlined word “diversion”(in Paragraph 2) most probably means “________”.
A.concentration B.change C.amusements D.stories

A.Students are becoming less interested in poetry.
B.Students are poorly educated in high school.
C.TV and the Internet are more attractive than poetry.
D.Poems have become difficult to understand.
59.In the last paragraph, the writer questions_______.
A.the difficulty in studying poems B.the way poems are taught in school
C.students’ wrong ideas about poetry D.the techniques used in writing poems
(D)
Between ten and midnight the United States is politically leaderless——there is no center of information anywhere in the nation except in the New York headquarters of the great broadcasting companies and the two great wire services.No candidate and no party can afford the investment on election night to match the news-gathering resources of the mass media; and so, as every citizen sits in his home watching his TV set or listening to his radio, he is the equal of any other in knowledge.There is nothing that can be done in these hours, for on one can any longer direct the great strike for America’s power; the polls have closed.Good or bad, whatever the decision.America will accept the decision——and cut down any man who goes against it, even though for millions the decision runs contrary to their own votes.The general vote is an expression of national will, the only substitute for violence and blood.Its decision is to be defended as one defends civilization itself.
There is nothing like this American expression of will in England or France, India or Russia or China.Only one other major nation in modern history has ever tried to elect its leader directly by mass, free, popular vote.This was the Weimar Republic of Germany, which modeled its unitary vote for national leaders on the American practice.Out of its experiment with the system it got Hitler.Americans have had Lincoln, Wilson and two Roosevelts.Nothing can be done when the voting returns are flooding in; the White House and its power will move to one or another of the two candidates, and all will know about it in the morning.But for these hours history stops.
76.Between ten p.m.and midnight, the United States has no leader because________.
