题型：不详难度：来源：

There is no doubt that much of the profit of a business—sometimes the whole of its success—depends upon the use of the odds and ends．The odds and ends are various small things，which are left over when the main things are produced．But they possess a real value of their own．
If a business，big or small，looked down upon these odds and ends，it would mean a big difference in the amount of the benefit of the business．Take a meat factory for instance， there are countless odds and ends—bones and hair，which can be made into glue and rope to increase its profit greatly．
Then，if we are college students，what about our odds and ends—the odd moments？ Take time for example．Every one of us has the exact same amount of it．Everyone’s success or failure depends on the use of their time．But everyone uses the time more or less in the same way．However，why many great men in science or art have made huge successes for themselves in the world？Because they have made best use of their odd moments．Take Thomas A．Edison， he never allowed his odd moments to slip by．He thought，planned，and tried his inventions．He always worked twenty hours out of each twenty-four．His inventions made him famous all over the world，and provided valuable wealth for the human beings．
So, remember this axiom：very busy people always find time for everything．However，people with great spare time find time for nothing．Is it very strange？Not at all！The question is how to gather up fragments of time and make full use of them．As many big businesses have found，that the real profit is in using the odds and ends．We also must do in this way to make best use of our odd moments and manage to be successful in something that we do．
小题1: What are odds and ends？

A．They are nothing useful．

B．They are various small，but valuable things．

C．They are the main things that factories produce．

D．They are odd moments students deny to gather up．

小题2: Why should the odds and ends be made full use of ？Because ____ ．

A．lots of factors in success or in failure depend on the best use of odds and ends

B．they control to possess a value of their own

C．they are various small things people don’t want

D．they are useless things left over when the main things are produced

小题3:What does the word “Axiom” in the fourth paragraph mean?

A．clear and evident without proof

B．statement accepted as true without proof of argument

C．statement that can be argued

D．regulation accepted in scientific usage

Is early childhood education really necessary? Early childhood education primarily focuses on learning through playing to develop the child’s physical, sensory, communicational and social development． Early childhood education has become a concern of the government, who pushes poor children to be formally trained before they are old enough for Kindergarten．
There are good reasons for the government to push early childhood education．Studies have shown that orphaned children who did not receive good care and education become developmentally delayed causing failure in school, and even in life．Further studies show that poor children who take part in Head Start programs are more prepared for school, less likely to end up in Special Education classes, and are less likely to receive public help or go to jail．
There are also negative parts to putting a child in formal education programs too early．Time Magazine online explains that “the younger the child the less his chances of catching up with first-grade work．” I have personally witnessed many children of my generation who went to Head Start programs become frustrated and bored with school before they finished high school．Yet parents have been sure that the earlier the child starts school, the better off he or she is, so they push to start children earlier．
Actually while early formal education of poor children does show great gains in the early elementary years, studies also show that this head start is really a “false start”, as the gains are lost in middle and high school years．It seems that environment is a bigger factor on life’s success than early education．Head Start programs have not achieved its original goal in closing the achievement gap in poor and middle school children．Perhaps it is time to find other ways to close that gap．
小题1:The purpose of the government valuing the early childhood education is ________．
A．to develop the children’s communication
A．to give orphaned children good care and education
C．to get the children prepared for the kindergarten
D．to train the children formally and regularly
小题2:According to the studies, which of the following is True?

A．Children with good early education may have a rich life．

B．The orphaned children are usually unhappy in their life．

C．Children without early education can do well at school．

D．Head Start programs are helpful to the poor children．

小题3:The author’s attitude toward the early childhood education is _________．

A．puzzling

B．objective

C．indifferent

D．approving

小题4:The main idea of the last passage is that __________．

A．the early childhood education is very necessary

B．Head Start programs have helped the children a lot

C．environment is the most important to life’s success

D．better ways should be found to help the poor children

“There is an out – of – date idea that children grow up and leave home when they’re 18,and the truth is far from that,” says Mr．Larry Bumpass of the University of Wisconsin．Today unexpected numbers of young adults are living with their parents．“There is a great change in the middle class,” declares Allan Schnaiberg of Northwestern University, whose son, 19, moved back in after an absence of eight months．
Scientists show a number of reasons for this return to the nest．The marriage age is rising, a condition that makes home and its pleasantness particularly attractive to young people．A high divorce （离婚） rate and a low remarriage rate make some differences．For some, the expense of an away - from - home college education has become so great that many students now attend local schools．Even after graduation, young people find their wings tied by terrible housing costs．
Living at home, says Knighton, a school teacher, continues to give security （安全保卫） and moral（道义的） support．Her mother agreed．“Its strange for the kids to pay all that money for rent．It makes sense for kids to stay at home．” But sharing the family home requires changes for all．There are the hassles over bathrooms, telephones and privacy．Some families, however, manage the careful balancing act．But for others, it proves too difficult．Michelle Del Turco, 24, has been home three times and left three times．“What I considered a social drink, my dad considered an alcohol （酒精） problem,” she explains．“He never liked anyone I dated, so I either had to hide away or meet them at friends" houses．”
Just how long should adult children live with their parents before moving on? Most scientists feel lengthy homecomings are a mistake．Children, can end up with a sense of defeat and failure．And aging parents,

who should be enjoying some freedom, find themselves stuck with too many things．Many agree that brief visits, however, can work well．
小题1:According to the author, there w

as once a trend in the U．S．________．

A．for young adults to leave their parents and live separately

Scientists are closely concerned with the structure of buildings and with the quality of building materials． The World health Organization （WHO) observes that the introduction of air conditioning and energy conservation （保护) measures have been accompanied by growing problems of indoor air quality． Some pollutants arise from insulation （隔音) products, some from moving cars, and others from modern housing materials． As many Europeans spend up to 90% of their lives in buildings, the health effects of the indoor climate are very important．
　　Some construction materials, including fiberboard, insulation foams and certain glues for man-made wood floor boards, for example, give out organic products such as formaldehyde （甲醛)． Heat and humidity increase the release of formaldehyde and the gas seriously harms the eyes． Paint, lacquer, etc． can also release dangerous gas into indoor air．
　　Construction materials can cause serious damage, especially when they contain asbestos（石棉）． Asbestos is naturally present in rock formations worldwide． It belongs to a family of mineral substances made up of solid, non-combustible（非易燃品） fiber． These properties make asbestos a highly sought-after construction material． As early as 1931, however, public health officers in t

he United Kingdom revealed the connection between breathing in asbestos dust and such diseases as lung cancer．
　　The land on which a building is sited may also contribute to pollution． Some kinds of granite or similar rocks contain traces of radium． As it breaks down, this naturally radioactive element produces some kind of radioactive gas that goes through tiny cracks in walls, floors and building materials, and makes its way into the building and the rooms． The better the homes are insulated, the more is the dangerous gas in indoor air． The main effect of this dangerous gas on health is to increase the risk of lung cancer．
小题1:What is the main idea of the passage?

A．Some building materials pollute indoor air．

B．Some factors cause indoor air pollution．

C．Asbestos can cause lung cancer．

D．The land on which houses are built contributes to indoor pollution．

小题2:Why are Europeans particularly concerned with building materials?

A．Lots of building materials there are radioactive．

B．They stay home up to 90% of their lives．

C．They have a high rate of lung cancer．

D．They spend most of their time indoors．

小题3:Why is asbestos a sought-after building material?

A．It is a kind of insulation foam．

B．Asbestos will not give out dangerous gas．

C．This material is not easy to catch fire．

D．It is rarely present in rock formations．

小题4:Why should we be careful about the land on which a building is to be sited?

A．To determine whether the land is firm enough for a building to be sited on．

B．To make sure that the land contains no radioactive material．

C．To make certain that the land releases no formaldehyde or other gases．

D．To check whether it contains any combustible materials．

The most exciting kind of education is also the most personal． Nothing can exceed （超越) the joy of discovering for yourself something that is important to you! It may be an idea or a bit of information you come across accidentally—or a sudden insight, fitting together pieces of information or working through a problem． Such personal encounters are the “payoff” in education． A teacher may direct you to learning and even encourage you in it—but no teacher can make the excitement or the joy happen． That"s up to you．

20090318

A research paper, assigned in a course and perhaps checked at various stages by an instructor, leads you beyond classrooms, beyond the texts for classes and into a process where the joy of discovery and learning can come to you many times． Preparing the research paper is an active and individual process, and ideal learning process． It provides a structure within which you can make exciting discoveries, of knowledge and of self, that are basic to education． But the research paper also gives you a chance to individualize a school assignment, to suit a piece of work to your own interests and abilities, to show others what you can do． Writing a research paper is more than just a classroom exercise． It is an experience in searching out, understanding and synthesizing（综合）, which forms the basis of many skills applicable（可利用的） to both academic and nonacademic tasks． It is, in the fullest sense, a discovering of an education． So, to produce a good research paper is both a useful and a thoroughly satisfying experience!To some, the thought of having to write an assigned number of pages, often more than ever produced before, is upsetting． To others, the very idea of having to work independently is threatening． But there is no need to approach paper assignment with anxiety, and nobody should view the research paper as an obstacle to overcome． Instead, consider it a goal to accomplish, a goal within reach if you use the help this book can give you．
小题1:According to the writer, personal discoveries ．

A．will give one encouragement and direction

B．are helpful in finding the right information

C．are the most valuable part of one"s personal education

D．will help one to successfully complete school assignments

A．to fully develop one"s personal abilities

B．to use the skills learnt in the classroom

C．to prove that one is a productive writer

D．to demonstrate how well one can accomplish school assignment

小题3:The writer argues in the passage that ．

A．one should explore new areas in research

B．one should trust one"s own ability to meet course requirements

C．one should consider research paper writing a pleasure, not a burden

D．one should use all one"s knowledge and skills when doing research

小题4:What will probably follow this passage?

A．How to write a research paper．

B．The importance of research in education．

C．How to make new discoveries for oneself．

D．The skill of putting pieces of information together．

Before astronauts can go into space, they have to have the right suit. That’s why NASA（美国国家航天和航空局）scientists are developing a new kind of space suit——lighter and more flexible than before. These new space suits will have lots of mobility(灵活性) for the astronauts, but will not need much maintenance. NASA wants the suits to include new technology that can help astronauts be safe in outer space.
Right now, the American space suit weighs about 275 pounds and is big and massive. But the suit is also easy to work in for long periods of time. The Russian space suit is less complicated, but is used only a few times and then gets thrown away.
“Finding the right balance is always going to be a challenge,” said a long-time astronaut Jeff Williams. Williams has worn both types of suits. Space suits protect astronauts from both extreme heat and freezing temperatures. They carry life-packs with oxygen for the astronauts. They also shield astronauts from radiation, or particles that send out harmful rays.
Scientists are using computers to design the new suits. This allows them to change the design again and again, and to even test the design out before actually making anything. “There’s a lot more capable tools and technology to get the job done——a lot more knowledge, as well,” said Joe Kosmo. Kosmo helped design, develop, and test suits during the Mercury, Gemini, Apollo, Skylab, and shuttle periods.
These new space suits will be much lighter and use a new kind of complex material. They also will have a smaller life support backpack, thanks to tiny electronics. NASA hopes to have the first prototypes(原型) in development by 2010 and certify(证明) the suit by 2012. This will be in time for the launch of the Orion spaceship in 2014.
小题1: What characteristic does the new space suit have?

A．The new space suit will need much maintenance.

B．The new space suit will be heavier than before.

C．The new space suit will have less mobility than before.

D．The new suit will use new technology to help astronauts be safe in outer space.

小题2:What’s the disadvantage of the Russian space suit?

A．The Russian space suit is big and massive.

B．The Russian space suit is much complicated.

C．The Russian space suit is merely used a few times.

D．The Russian space suit is easy to work in for long periods of time.

小题3:The underlined word “shield” in the third paragraph might mean_______.

A．harm

B．protect

C．help

D．warn

小题4:Why can scientists test the design out before actually making the new space suits?

A．Because designing the new space suit is not a complex task.

B．Because computers are being used to help scientists design the new space suits.

C．Because it needs little knowledge to design the new space suits.

D．Because the scientists only change the old space suits a little and make them into the new ones.

小题5:How long will it take scientists to put the new space suits from prototypes into the first practical use?

A．Two years.

B．Three years.

C．Four years.

D．Six years.
