The word “conservation” has a thrifty meaning. To conserve is to save and protect, to leave what we ourselves enjoy in such a good condition that other s may also share the enjoyment. Our forefathers had no idea that human population would increase faster than the supplies of raw materials: most of them, even until very recently, had the foolish ideas that the treasures were “limitless” and could “last forever”. Most of the citizens of earlier generations knew little or nothing about the complicated and delicate system that runs all through nature, and which means that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to others.

Fifty years ago, nature study was not part of school work: scientific forestry was a new idea; wood was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; nobody had yet studied long-term climate cycles in relation to proper land use; even the word “conservation” had nothing of the meaning that it has for us today.

For the sake of ourselves and those who will come after us, we must now set about correcting the mistakes of our forefathers .Conservation should be made part of everybody’s daily life. To know about the water table in ground is jus as important to us as knowledge of the basic math formulas. We need to know why all watersheds need the protection of planet life and why the running, current of streams and rivers must the duly of planting trees as well as of cutting them. We need to know the importance of big, grown trees, because living space for most man’s fellow creatures on this planet is figured not only in square measures of surface but also in cubic volume above the earth. In a word, it should be our goal to restore as much as the original beautify of nature as we can.

The Colors of Friendship友谊的颜色

Once upon a time the colors of the world started to quarrel. Green said, “Clearly I am the most important. I am the sign of life and hope. I was chosen for grass, trees and leaves. Without me, all animals would ___1__.”

Doing as they were told, the colors __18__ and joined hands. They formed a colorful rainbow. From then on, whenever a good rain ___19__ the world, a rainbow appears in the sky. They remember to __20__ one another.

In the old days, children were familiar with birth and death as part of life. Now this is perhaps the first generation of American youngsters who have never been close by during of the birth 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）in patients— even when those patients are their parents. This deprives（剥夺）the dying patient of family members during the last few days of his life 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 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 quite aware of its potential outcome.

It is important for family members, and doctors and nurses to understand these patients’ communication 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 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 cope with the coming of death and finally to reach a true stage of acceptance before death.

The elders of today's Americans _______ .

A. are often absent when a family member is born or dying

B. are unfamiliar with birth and death

C. usually see the birth or death of a family member

D. have often experienced the fear of death as part of life

Children in America are deprived of the chance to________.

A. visit a patient at hospital   B. visit their family members

C. learn how to face death    D. look after the patients

The need of a dying patient for people to accompany him shows________.

A. his wish for communication with other people      B. his fear of death   

C. his unwillingness to die             D. he feels very upset about his condition

It may be concluded from the passage that________.

A. dying patients should be truthfully informed of their condition

B. dying patients are afraid of being told of the coming of death

C. most patients are unable to accept death until it can’t be avoided

D. most doctors and nurses understand what dying patients need

In June,2007,a group of students from eight high schools in Winnipeg,the capital of Canada’s Manitoba province,will begin test-launching(试发射)a satellite the size of a Rubik’s cube.

The one-kilogram Win-Cube satellite,named for its home city and its shape,will be put into low orbit.Once in space,it can perform for a few months or up to several years,communicating information that could help find the early signs of earthquakes.

There are 80 similar satellite projects worldwide,but this is the first high-school based program of its kind in Canada.30 Manitoba high school students are having a hand in designing and building the satellite,in cooperation with aerospace(航空航天的)experts and 10 students from the University of Manitoba,and with support from two other organizations.

The Win-Cube project is not something that goes on a piece of paper,it is real-world engineering,allowing high school students to have an opportunity to learn more about the exciting world of engineering through their participation in this challenging program.It is also taken as a wonderful example of the unique partnerships within Manitoba.Designing,building and lauching a satellite with high-school participation will bring this world-class educational project into reality and Manitoba closer to space.

“These Manitoba high school students deserve congratulations for their enthusiasm, innovation(创新)，and a strong love for discovery,”said Education,Citizenship and Youth Minister Peter Bjornson.“We want to make science more relevant(相关的),interesting and attractive to high school students by showing them how classroom studies can relate to practical experience in the workplace or,in this case,in space,”Bjornson added.

The Win-Cube program is mainly aimed at inspiring a strong desire for discovery on the part of the students.It also shows Manitoba’s devotion to research and innovation and the development of a skilled workforce—all important drivers of knowledge-based economic growth.

According to the passage,the Win-Cube satellite is_______.

A.named after Manitoba and its shape

B.intended for international communication

C.designed like a Rubik’s cube both in shape and size

D.challenged by university students around the world

According to Mr.Bjornson,_______.

A.those Manitoba high school students are worth praising

B.the study of space can be practically made in classroom

C.Manitoba high schools are famous for the sutdy of space

D.scientific research is too far away from high school students

The primary purpose of the project is to_______.

A.find the early signs of earthquakes

B.relate studies to practical experience

C.help high school students study real-world engineering

D.inspire a strong desire for discovery among the students

The best title for this passage may be_______.

A.Manitoba School                                           B.Win-Cube Program

C.Space Cooperation                                        D.Satellite Launching
