？？？？？？？？？？？？Questions 11 to 15 are based on the following passage:？？？？
？？It is recently estimated that the book industry is trying to get a good read on its future. These days, instead of turning paper pages, many readers reach for hand held devices. These electronic readers not only Store books to show on a screen, they can also read them out loud.？？？？
？？Last week, Amazon lowered the price of its Kindle reader by 60 dollars to just under 300 dollars. The device can download books wirelessly from a store on Amazon&39;s Website. Most new releases and best sellers cost 9 dollars and 99 cents. Newspapers, magazines and other services are available for a monthly charge. Buyers of e-books get a good deal: Traditional hard cover books often cost around 25 dollars. But what about book publishers and writers？ Their concerns about profits are like the ones voiced as the Internet began to change the music industry. Many e-books are already selling for 99 cents.？？
？？Books printed on paper are easily shared and resold by anyone But e-books can act more like computer software licensed only to the user who buys them.And some Kindle users got a shock last week. They were surprised to find that copies of two books disappeared from their devices. These were 99 cent versions of George Or well&39;s 1984 and Animal Farm. Blogger shave had fun pointing out that 1984 is largely about censorship(审查制度）-the suppression of information in a society led by Big Brother. Amazon explained that it did not have the rights to the books, so it erased them and returned the people&39;s money.？？
？？This week, Barnes & Noble, the world&39;s largest bookseller, launched what it calls the world&39;s largest e-bookstore. People can read the books on the Apple iPhone and other hand held devices and personal computers. They can also download over a half million books available free from Google. The Internet search company is putting books online that are no longer protected by copy right.
But last October, Google reached a 125 million dollar legal settlement to also make parts of some copy righted books available. That deal with two groups of writers and publishers has raised competition（竞争）issues. The Justice Department is now investigating. Also, the European Union plans hearings in September on how European writers might be affected.

Researchers have established that when people are mentally engaged, biochemical changes occur in the brain that allow it to act more effectively in cognitive areas such as attention and memory. This is true regardless of age.
People will be alert and receptive if they are faced with information that gets them to think about things they are interested in. And someone with a history of doing more rather than less will go into old age more cognitively sound than someone who has not had an active mind.
Many experts are so convinced of the benefits of challenging the brain that they are putting the theory to work in their own lives. “The idea is not necessarily to learn to memorize enormous amounts of information,” says James Fozard, associate director of the National Institute on Again. “Most of us don't need that kindof skill. Such specific training is of less interest than being able to maintain mental alertness.” Fozard and others say they challenge their brains with different mental skill, both because they enjoy them and because they are sure that their range of activities will help the way their brains work.
Gene Cohen, acting director of the same institute, suggests that people in their old age should engage in mental and physical activities individually as well as in groups. Cohen says that we are frequently advised to keep physically active as we age, but older people need to keep mentally active as well. Those who do are more likely to maintain their intellectual abilities and to be generally happier and better adjusted. “The point is, you need to do both,” Cohen says. “Intellectual activity actually influences brain-cell health and size.”
6. People who are cognitively healthy are those _______.
A、who can remember large amounts of information
B、who are highly intelligent
C、whose minds are alert and receptive
D、who are good at recognizing different sounds
7. According to Fozards argument people can make their brains work more efficiently by _______.
A、constantly doing memory work
B、taking part in various mental activities
C、going through specific training
D、making frequent adjustments
8. The findings of James and other scientists in their work _________.
A、remain a theory to further proved
B、have been challenged by many other experts
C、have been generally accepted
D、are practiced by the researchers themselves
9. Older people are generally advised to ___________.
A、keep fit by going in for physical activities
B、keep mentally active by challenges through specific training
C、maintain mental alertness through specific training
D、maintain a balance between individual and group activities
10. What is the passage mainly about?
A、How biochemical changes occur in the human brain.
B、Why people should keep active not only physically but also mentally.
C、How intellectual activities influence brain-cell health
D、Why people should receive special mental training as they age.
