| 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 experiment, test subjects（受试者）were connected to scanning equipment and shown two numbers on a screen. They were then asked to choose between adding or subtracting（减）the two numbers. Using this method, researchers were able to follow brain processes and make the correct assumptions（假设）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. | |

A. Some equipment is able to read human minds.
B. Some progress has been made in mind reading.
C. Test subjects have been used to make decisions.
D. Computer programs can copy brain processes.
47. People laugh when tickled by others because the feeling is _______.
A. unexpected B. expected C. comfortable D. uncomfortable

A. Ms. Leon B. Mr. Lewis C. Mr. Moeller D. Dr. Jeffers
49. According to the text, Jeffers is probably _______.
A. a computer programmer B. a test subject

NOT all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares.
Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly erase(抹去) the effect of painful memories.
In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased.
The research has caused a great deal of argument. Some think it is a bad idea, while others support it.
Supporters say it could lead to pills that prevent or treat soldiers’ troubling memories after war. They say that there are many people who suffer from terrible memories.
“Some memories can ruin people’s lives. They come back to you when you don’t want to have them in a daydream or nightmare. They usually come with very painful emotions,” said Roger Pitman, a professor of psychiatryat Harvard Medical School. : “This could relieve a lot of that suffering.”
But those who are against the research say that changing memories is very dangerous because memories give us our identity（特质）. They also help us all avoid the mistakes of the past.
“All of us can think of bad events in our lives that were horrible at the time but make us who we are. I’m not sure we want to wipe those memories out,” said Rebecca Dresser, a medical ethicist
53．The passage is mainly about .
A．a new medical invention

A．people doubt t he effects of the pills
B．the pill will stop people’s bad experiences
C．taking the pill will do harm to people’s health
D．the pill has probably been produced in America
56．Which of the following does Rebecca Dresser agree with?
A．Some memories can ruin people’s lives.
B．People want to get rid of bad memories.
C．Experiencing bad events makes us different from others.
D．The pill will reduce people’s sufferings from bad memories.
