[单选题]第一节 （共15小题，每小题2分，满分30分）阅读下列四篇短文，从每小题后所给的A、B、C、D四个选项中，选出最佳选项，并在答题卡上将该选项涂黑。

A. A
B. Ask Dr ? Jeffers
C. This month Dr. Jeffers is answering questions about the human brain and how it works.
D. Dear Dr. Jeffers,
E. 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/
F. —Jane Leon, New York, USA
G. Dear Ms. Leon,
H. 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.
I. —Dr. J.
J. Dear Dr. Jeffers,
K. 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?
L. —Glenn Lewis, Vancouver, Canada
M. Dear Mr. Lewis,
N. 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.
O. —Dr. J.
P. 46.What can we learn from the answer to the first question?
Q. Some equipment is able to read human minds.
R. Some progress has been made in mind reading.
S. Test subjects have been used tomake decisions.
T. Computer programs can copy brain processes.
