　　HUMANS have spent years exploring space, but how much do we know about deep inside the planet on which we live? The idea of exploring the earth's core (地核)was detailed in an article called“Modest Proposal (建议)”. It was written in May by American scientist David Stevenson. It is similar idea to an American sci-fi movie that was released in March, The Core.

　　So, because they deal with the same topic, it wouldn't be too strange to compare a scientific report with a sci-fi movie.

　　Why explore

　　The report: The solid inner core of the earth is fluid(不固定的)and responsible for the earth's magnetic field (磁场). * Scientists don't know exactly why all this is so, nor do they know the exact make-up or temperature of the core. *

　　The movie: An unknown force has caused the earth's inner core to stop rotating (旋转). With the planet's magnetic field rapidly decreasing, our atmosphere starts to come apart.

　　The result is deadly: birds lose their ability to fly in the right direction and the earth eventually (最终)becomes like a microwave oven (微波炉), cooked by the sun.

　　How explore

　　The report: A nuclear explosion (核爆炸)would be the best way to create a hole big enough to enter the earth. The crack (裂缝)needs to be as long and as deep as several football fields, but only about 30era wide. * The event would be as powerful as an earthquake measuring 7 on the Richter Scale (里氏震级).*

　　At least 100,000 tons of hot iron would be poured into the crack, along with a metal probe (探测器)the size of a grapefruit (柚子).

The weight of the iron, which is much denser than earth' s outer regions, would open a gap all the way to the planet core, about 3,000kin below. The probe would fall at about 16kin per hour as the crack doses up behind it. * Stevenson said the amount of iron needed is equal to what' s produced in factories around the world in a week. *

　　The movie: Send a manned vehicle that looks like a windowless subway (地铁)train into the earth's core. Virgil, the ship, is made of a metal that can stand the extreme temperature and pressure found in the core.

　　Virgil began its journey when it was dropped in the middle of the ocean because this is where the crust (地壳)is thinnest.

　　What to do

　　The report: The weeks-long mission would measure the temperature and chemical composition (make-up)of the core.

　　The movie: Blow up five 200-megaton (兆吨)nuclear bombs to restart the core.

Choose the best choice according to the story________.

(1)What do the report and the movie have in common?

[　　]

A．Both deal with exploring space.

B．Both deal with going deep to the inside of the earth.

C．Both offer the same reason to explore the earth's core.

D．Both consider it possible for the core to stop rata- ring.

(2)In the movie, a nuclear explosion would ________.

[　　]

A．help man enter the earth

B．create a big crack that leads to the earth's core

C．produce hot iron

D．make the earth's core work again

(3)How long would it take the probe to reach the core according to the report? ________.

[　　]

A．About 30 hours.

B．About 200 hours.

C．About 8 or 9 days.

D．A few weeks.

(4)What does the underlined word“stand”mean? ________

[　　]

A．Rise.

B．Change.

C．Measure.

D．Resist successfully.

(5)We can infer from the passage that the core________.

[　　]

A．is in the danger of stopping rotating

B．still has a lot for us to explore

C．controls the birds' sense of directions

D．might blow up

答案：B;D;C;D;B

　　As far back as 700 B.C., man had talked about children being cared for by wolves. Romulus and Remus, the old story twin founders of Rome, were said to have been cared for by wolves. It is believed that when a she-wolf loses her baby, she tries to get a human child to take its place. This idea did not become believable until the late nineteenth century when a French doctor actually found a ten-year-old boy having nothing on walking around in the woods. He didn't walk upright, could not speak, nor could he relate to people. He only growled(嗥叫)and stared at them. Finally the doctor won the boy's confidence (信任) and began to work with him. After many long years of devoted and patient teaching, the doctor was able to get the boy to dress, feed himself, recognize and say a number of words, as well as write letters to form words.

　　The desire to make explorations is born with man．Wherever his imagination goes, man also has a strong wish to go．A large part of human history is connected with the exploration of the world in which we live．Again and again people have set out with surprising courage and patience to look into unknown regions and lands to see what had not yet been seen, to make known the unknown．With kites, balloons and aircraft they left the ground to pass through the lower atmosphere．Now the outer space receives their attention．

　　Why should man take the trouble of conquering space?It is hard to list the specific practical benefits that will result in．But one knows, from past experience in other areas, that man will surely see and discover new things in space that will increase our scientific knowledge, and this new knowledge will find its way into valuable practical uses．What we learn about man himself, from his experience in space, and from the effects of space and the space flight environment on him, will be extremely valuable．The new techniques developed to cany out the exploration of space, and to keep man alive in space, will certainly find practical uses in everyday life in some way．The areas that will benefit are manifold．They include communication, generation of power, transportation and travel, food production, materials, fuels and many others．But to say definitely just what the practical results will be is almost impossible．

　　When students and parents are asked to rate subjects according to their importance, the arts are unavoidably at the bottom of the list．Music is nice, people seem to say, but not important．Too often it is viewed as mere entertainment, but certainly not an education priority(优先)．This view is shortsighted．In fact, music education is beneficial and important for all students．

　　Music tells us who we are．Because music is an expression of the beings who create it, it reflects their thinking and values, as well ad the social environment it came influence that George Gershwin and other musicians introduced into their music is obviously American because it came from American musical traditions．Music expresses our character and values．It gives us identity as a society．

　　Music provides a kind of perception(感知)that cannot be acquired any other way．Science can explain how the sun rises and sets．The arts explore the emotive(情感的)meaning of the same phenomenon．We need every possible way to discover and respond to our world for one simple but powerful reason：No one way can get it all．

　　The arts are forms of thought as powerful in what they communicate as mathematical and scientific symbols．They are ways we human beings“talk”to each other．They are the language of civilization through which we express our fears, our curiosities, our hungers, our discoveries, our hopes．The arts are ways we give form to our ideas and imagination so that they can be shared with others．When we do not give children access to an important way of expressing themselves such as music, we take away from them the meanings that music expresses．

　　Science and technology do not tell us what it means to be human．The arts do．Music is an important way we express human suffering, celebration, the meaning and value of peace and love．

　　So music education is far more necessary than people seem to realize．

(1)

According to Paragraph 1, students ________．
[　　]
A．	regard music as a way of entertainment
B．	disagree with their parents on education
C．	view music as an overlooked subject

(3)

According to the passage, the arts and science ________．
[　　]
A．	approach the world from different angles
B．	explore different phenomena of the world
C．	express people’s feelings in different ways
D．	explain what it means to be human differently

(4)

What is the main idea of the passage?
[　　]
A．	Music education deserves more attention．
B．	Music should be of top education priority．

　　There are robots all around us．Some do very complicated jobs like flying airplanes and driving subway trains．And some do one simple job．When an automatic washing machine is switched on, water pours in．The machine waits until the water is warm enough for washing clothes．It does this by “feedback”(反馈)．Information about what is happening is feedback into the robot to tell what to do next．Our eyes, ears and other senses are our feedback．They tell us what is going on around us．So robots are like human beings in two ways．They work and they have feedback．

　　In some ways robots are better than human beings．They work quickly and do not make mistakes．They do not get bored doing the same job over and over again．And they never get tired．So robots are very useful in factories．They can be taught to do many different jobs．First their electronic brain must be shown how the job is done．A person moves the robot’s “arms” and “hands” through each part of the job．

　　The most intelligent robots can move and see．Their eyes are cameras．Their fingers can feel shapes and sizes of the objects．These robots have computer brains linked to their eyes and fingers, which control their actions．The most intelligent robots--cave robots are used in scientific research．They do such job as handling radioactive materials．

　　In the old days, children were familiar with birth and death as part of life．This is perhaps the first generation of American youngsters who have never been close by during the birth of a baby and have never experienced the death of a family member．

　　Nowadays when people grow old, we often send them to nursing homes．When they get sick, we send them to a hospital, where children are forbidden to visit terminally(晚期的)ill patients – even when those patients are their parents．This deprives(剥夺)the dying patient of significant family members during the last few days of his and it deprives the children of an experience of death, which is an important learning experience．

　　Some of my colleagues and I once interviewed and followed about 500 terminally ill patients in order to find out what they could teach us and how we could be of more benefit, not just to them but to the members of their families as well．We were most impressed by the fact that even those patients who were not told of their serious illness were aware of its possible result．

　　It is important for family members, and doctors and nurses to understand these patients’ communications in order to truly understand their needs, fears and fantasies．Most of our patients welcomed another human being with whom they could talk openly, honestly, and frankly(坦白地)about their trouble．Many of them shared with us their great need to be informed, to be kept up-to-date on their medical condition and to be told when the end was near．We found out that patients who had been dealt with openly and frankly were better able to deal with the coming of death and finally to reach a true stage of acceptance prior(在先的)to death．

(1)

The elders in America today _______．
[　　]
A．	were often absent when a family member was born or dying
B．	were quite unfamiliar with birth and death
C．	usually saw the birth or death of a family member
D．	had often experienced the fear of death as part of life

(2)

Children in America today are deprived of the chance ________．
[　　]
A．	to learn how to face death
B．	to visit their family members
C．	to look after patients
D．	to have access to a hospital

(3)

Five hundred terminally ill patients were interviewed with the main purpose of．
[　　]
A．	observing how they reacted to the crisis of death
B．	helping them and their families overcome the fear of death
C．	finding out their attitude towards the coming of death
D．	learning how to best help them and their families

(4)

What may be concluded from the text?
[　　]
A．	Dying patients are afraid of being told of the coming of death．
B．	Most doctors and nurses understand what dying patients need．
C．	Dying patients should be truthfully informed of their condition．
D．	Most patients are unable to accept death until it can’t be avoided．
