阅读理解     A new book claims to have definitive evidence of a long-suspected technological crime-that Alexander
Graham Bell stole ideas for the telephone from a competitor, Elisha Gray.
     In The Telephone Gambit:Chasing Alexander Graham Bell"s Secret,journalist Seth Shulman argues
that Bell-aided by aggressive lawyers and a corrupt patent examiner-got an improper glance at patent
documents Gray had filed,and that Bell was incorrectly credited with filing first.
     Shulman believes the smoking gun is Bell"s lab notebook,which was limited by Bell"s family until 1976,
then digitized and made widely available in 1999.
     The notebook details the false starts Bell met as he and assistant Thomas Watson tried transmitting
sound electromagnetically over a wire.Then,after a 12-day gap in 1876-when Bell went to Washington to
sort out patent questions about his work-he suddenly began trying another kind of voice transmitter.That
method was the one that proved successful.
     As Bell described that new approach,he drew a diagram of a person speaking into a device.Gray"s
patent documents,which described a similar technique,also featured a very similar diagram.
     Shulman"s book describes other elements that have angered researchers" suspicions. For instance,Bell"s
transmitter design appears hastily(草率地) written in the margin of his patent; Bell was nervous about
demonstrating his device with Gray present; Bell resisted testifying(作证) in an 1878 lawsuit solving this
question; and Bell,as if ashamed,quickly distanced himself from the telephone patent right bearing his name.
     Perhaps the most instructive lesson comes when Shulman explores why historical memory has favoured
Bell but not Gray-nor German inventor Philipp Reis.who beat them both with 1860s telephones that
employed a different principle.
     One reason is simply that Bell,not Gray.actually demonstrated a phone that transmitted speech.Gray
was focused instead on his era"s pressing communications challenge:how to send multiple messages
simultaneously(同时地) over the same telegraph wire.As Gray shouted to his lawyers,"I should like to
see Bell do that with his instruments."1.The phrase"the smoking gun"in Paragraph 3 means"        ".  A.the cause of a series of things            
B.something proving what one has done
C.the conclusion of a complex case        
D.something used to confuse people2.According to Shulman,how did Bell steal the idea for telephone from Gray?A.He secretly looked at Gray"s patent documents.
B.He watched secretly while Gray was experimenting.
C.He was told the new technique by Gray"s assistant.
D.He learned the new technique from the patent examiner.3.How many examples are given by Shulman to prove that Bell stole the idea? A.3.                
B.4.              
C.5.            
D.6.

4.History treats Bell as the inventor of telephone because        .


A.he had written transmitter design in his patent
B.he founded a telephone company bearing his name
C.he proved how to send many messages at the same time
D.he made an actual demonstration of transmitting speech

阅读理解     If you want to improve your child"s results at school, you could do a lot worse than ensuring that they
do plenty of exercise.Scientists have already shown that physical activity can make you brainier.But
a team in America has used scans to show that an important part of the brain actually grows in children
who are fit.These youngsters tend to be more intelligent and have better memories than those who are
inactive.
     Scientists also found that one of the most important parts of their brains was 12 percent larger than
those of unfit children.They believe that encouraging children to take exercise from a very young age
could help them do better at school later.Researchers from the University of Illinois, in the U.S.,
studied the brains of 49 children aged nine and ten using a magnetic resonance imaging scan (核磁共振
摄影扫描), a technique which provides very detailed pictures of organs and tissues in the body.
     They also tested the fitness levels of the children by making them run on a treadmill (跑步机).The
scientists found that the hippocampus, a part of the brain responsible for memory and learning, was around
12 percent larger in the fitter children.
     Professor Art Kramer, who led the study published in the journal Brain Research, said the findings had
important implications for encouraging individuals to take part in sport from a young age."We knew that
experience and environmental factors and socioeconomic status all impact brain development," he said.
"If you get some terrible genes from your parents, you can"t really fix that, and it"s not easy to do something
about your economic status.But here"s something that we can do something about."1.If you want to improve your children"s result in school, ____________.A.it is worse to ensure that they do plenty of exercise
B.you can have their brain scanned
C.it could be better to make sure that they do a lot of exercise
D.you can do a lot except ensuring that they do exercise2.According to the passage, which of the following statements is NOT true?A.The fitness level of the children is linked to their intelligence.
B.Children who have a larger hippocampus will probably have better memories.
C.You can do something about the genes from your parents.
D.Unhealthy children will probably have a smaller hippocampus than others3.All the following factors that have some influence on one"s brain are mentioned EXCEPT
____________.A.genetic factor    
B.economic status  
C.physical fitness  
D.economic development

     Some scientists say that animals in the oceans are increasingly threatened by noise pollution caused by
human beings.
     The noise that affects sea creatures comes from a number of human activities. It is caused mainly by
industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals
themselves.
     Decibels (分贝) measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and
ninety-five would have the same effect.
     Some scientists have suggested setting a noise limit of one hundred and twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales.
     A team of American and Canadian scientists discovered that louder noises can seriously injure some
animals. The research team found that powerful underwater explosions were causing whales in the area to
lose their hearing. This seriously affected the whales" ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed(流血)and become infected
(感染).
     Many researchers whose work depends on ocean sounds are against a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research.
     Scientists do not know how much and what kinds of noises are harmful to ocean animals. However,
many scientists suspect(怀疑)that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.
1. According to the passage, which of the following is increasingly dangerous to sea creatures?
A. The noises of human activities.    
B. The noises made by themselves.
C. The sound of earthquakes.
D. The sound of the ice-breaking.
2. Which of the following is discussed in the third paragraph?
A. Different places with different types of noises.
B. The very human ears sensitive to all types of noises.
C. The same noise measured differently on land and in the ocean.
D. The ocean animals" reaction to noises.
3. According to the passage, what will scientists most probably do in the future?
A. They will try their best to decrease noise.
B. They will work hard to cut down noise pollution.
C. They will study the effect of different noises.
D. They will protect animals from harmful noises.

阅读理解     Last year college students in America spent an estimated $700 on textbooks on average. The
National Association of College Stores reported more than five billion dollars in sales of textbooks
and course materials.
    The association spokesman Charles Schmidt says electronic textbooks now just make up
2%~3% of sales. But he says that is expected to reach 10%~15% by 2012.
      Online versions(版本) are now available for many of the most popular college textbooks. An
etextbook can cost half the price of a new print textbook.But students usually lose access to them
after the end of the term.And the books cannot be placed on more than one device(设备), so they
are not easy to share.
     So what do students think of etextbooks?Administrators at Northwest Missouri State University
wanted to find it out.Earlier this year they tested them with 500 students in 20 classes.
    The university is unusual.It provides laptop computers for all 7,000 of its fulltime students.It does
not require students to buy their textbooks either.They rent them to save money.The school aims to
save even more by moving to etextbooks.
     The students in the survey reported that downloading the books from the Internet was easy.They
liked the idea of carrying lighter backpacks.And 56% said they were better able to find information.
     But most found that using etextbooks did not change their study habits.And 60% felt they read
more when they were reading on paper.In all, almost half the students said they still liked physical
textbooks better.
     But the survey found that cost could be a big influence.55% said they would choose etextbooks
if using them meant their textbook rental fee would not increase.
     Roger Von Holzen heads the Center for Information Technology in Education at Northwest
Missouri State University.He tells us that administrators are disappointed with the etextbooks now
available because the majority are not interactive(交互式的).
     He thinks growth will come when more digital books include video, activities, games and other
ways to interact with the information.The technology is improving.But for now, most of the books
are just words on a screen.

1. Etextbooks are not better than paper books in that________.

A. they cost more money              
B. they"re difficult to carry
C. they"re not convenient to share        
D. they can"t be downloaded from the Internet

2. How many surveyed students think paper books make better reading?

A. 60%.
B. 56%.
C. 55%.
D. 50%.

3. It can be inferred from the text that in the future________.

A. digital books will be more popular      
B. the digital books available need improvement
C. free digital books are available online      
D. digital books will replace print textbooks

     Today, innovations(创新) to make our lives more eco-friendly can be found everywhere. There are
energy-efficient automobiles, eco-friendly light bulbs, and clothes made by fashion designers using
sustainable(可持续的) environmental practices. Industries around the world have also begun to take a
serious look at how their operations affect the local and global environment.
     The university of Colorado has been named one of the top green colleges and universities in the United States. This university was one of the first to start a student-led recycling program in the 1970s and today
supplies students with reusable shopping bags to use both on and off campus. The entire University of
Colorado also uses low flow water fixtures(设备) and has reduced water usage by 40 percent since 2002.
     When it comes to going green, Warren Wilson College has been recognized in many places. The
Sierra Club and The Princeton Review have named the college as one of America"s greenest colleges and universities, while the school has also received the Outstanding College Recycling Award from the
Carolina Recycling Association, as well as awards from the Association for the Advancement of
Sustainability in Higher Education(AASHE). For a small college, Warren Wilson has made enormous
efforts to be an eco-friendly campus since its beginning, and today owns a campus farm, a seeding
program, and an extensive recycling program. Warren Wilson was also the first College to have an LEED platinum certified(白金认证的) residence hall, and its building services department is also 100 percent
GreenSeal certified. According to College Stats, Warren Wilson College is one of the first institutions in the United States to be almost completely self-sufficient(自给自足的) while also engaging students to
incorporate sustainability into all academic programs.
     Going green efforts at Oberlin College have not gone unnoticed. Oberlin College spends 22 percent of
its food budget on buying food from local farmers, with most of the food raised or harvested with organic
and sustainable practices. Oberlin has also stopped selling bottled water on campus and offers discounts to students who use their own storage containers when purchasing beverages and food items. Among
