          Ask Dr. Jeffers This month Dr. Jeffers is answering questions
about the human brain and how it works.
Dear Dr. Jeffers,  
     One of my colleagues, Felix Moeller, told me that scientists are learning to use computer to
'read minds'. Is there any truth to this story? -Jane Leon, New York, USA Dear Ms. Leon, Well,
a lot of research is being conducted in this area, but so far, the brain scanning equipment and
corresponding computer programs haven't been able to actually read thoughts. In one ex  periment,
test subjects(受試者)were connected to scanning equipment and shown two numbers on a screen.
They were then asked to choose between adding or subtracting(減)the two numbers. Using this
method, researchers were able to follow brain processes and make the correct assumptions(假設(shè))
70 percent of the time. It's not quite mind reading, but it's certainly a first step. 
-Dr. J.
Dear Dr. Jeffers,  
     My three-year-old son loves it when I dig my fingers into his sides and tickle(胳肢)him until he
laughs uncontrollably. The other day I noticed him trying to tickle himself but he couldn't do it.
Why not?
-Glenn Lewis, Vancouver, Canada
Dear Mr. Lewis,
     It's because of how the brain works. The brain is trained to know what to pay attention to and
what to ignore. It causes us to ignore physical feelings we expect to happen, but it causes a mild panic
reaction when there is an unexpected feeling. For example, you don't notice how your shoulder feels
while you're walking down the street. But if someone comes up behind you and touches you lightly on
the shoulder, you may jump in fear. It's that unexpected part that causes the tickle reaction.
-Dr. J.
                                       
1. What can we learn from the answer to the first question?    
A. Some equipment is able to read human minds.
B. Test subjects have been used to make decisions.
C. Some progress has been made in mind reading.
D. Computer programs can copy brain processes.
2. People laugh when tickled by others because the feeling is _____.    
A. expected          
B. unexpected        
C. comfortable        
D. uncomfortable
3. According to the text, Jeffers is probably _____.   
A. a computer programmer                
B. a medical doctor
C. a test subject                          
D. a human brain expert

 A new survey finds that more than eighty percent of Internet users in the United States search for health information online. The survey found that searching online is one of the leading ways that people look for a second opinion though doctors are still the main source of health information.
Forty-four percent of people are actually looking for doctors or other providers when they search for health information online. Another finding of the survey: Two-thirds of Internet users look online for information about a specific disease or medical condition.
The Internet has also become an important source of emotional support for people with health problems. Susannah Fox says one in five Internet users has gone online to find other people who have the same condition. It was more popular among people with more serious health issues—one in four people living with chronic diseases (慢性病). And it was basically off the charts with people living with rare disease. They are so eager to find other people online who share their health concerns.
A disease is considered rare if it affects fewer than two hundred thousand people worldwide. The rise of social networking has made it easier for people with rare diseases to connect with each other and feel less alone. Social networking is also changing the way some doctors and patients communicate with each other. Dr. Jeff Livingston operates a medical center for women in Irving, Texas. His office uses password-protected software to share information with patients.
“We provide the patient full access to their medical care. Anything I can see, the patient can see. All of their notes, all of their doctor visits are right there. All of their lab work is right there.” Dr. Livingston says the software has increased efficiency, reduced costs and improved relations with patients.
【小題1】From the first paragraph, we can know _________.

A．most online health information is reliable
B．more people now turn to the Internet for medical advice
C．people shouldn’t rely on the Internet for medical advice
D．doctors are no longer the patients’ first choice
【小題2】 The underlined words “off the charts” in Paragraph 3 mean _________.
A．very popularB．not accessibleC．far away fromD．not attractive
【小題3】 By using social networking, patients with rare diseases can _________.
A．find effective curesB．get emotional comfort
C．a(chǎn)sk for financial supportD．consult doctors anytime
【小題4】 Which of the following is NOT true of Dr. Livingston’s software?
A．It cuts down medical expenses.
B．It decreases the time spent on medical care.
C．It takes doctors closer to their patients.
D．It gives patients a medical test online.
