In one study, researchers examined the brain of a learning disabled person who had died in an accident. They found two unusual things. One involved cells in the left side of the brain, which control language. These cells normally are white. In the learning disabled person, however, these ceils were gray. The researchers also found that many of the nerve ceils were not in a line the way they should have been. The nerve cells were mixed together.
The study was carried out under the guidance of Norman Geschwind, an early expert on learning disabilities. Doctor Geschwind proposed that learning disabilities mainly resultes from problems in the left side of the brain. He believed this side of the brain failed to develop normally. Probably, he said, nerve cells there didn't connect as they should. So the brain was like an electrical device in which the wires were crossed.
Other researchers didn't examine brain tissue. Instead, they measured the brain's electrical activity and made a map of the electrical signals.
Frank Dully experimented with this technique at Children's Hospital Medical Center in Boston. Dr. Duffy found large differences in the brain activity of normal children and those with reading problems. The differences appeared throughout the brain. Dr. Dully said his research is evidence that reading disabilities involve damage to a wide area of the brain, not just the left side.
Scientists found that the brain cells of a learning disabled person differ from those of a normal person in ______.
A．structure and function
B．color and function
C．size and arrangement
D．color and arrangement

M: I recently read that in ten years we'll wearing clothes that change with the weather. So when it's cold, our clothes will warm up, and when it's hot, our clothes will cool off.
W: Oh, very funny. So we'll be wearing huge clothes with built-in air conditioners and heaters.
M: I'm serious. Researchers have discovered a method of treating fibers with plastic crystals which can store and release heat as the temperature changes. These treated fibers absorb more heat than untreated fibers. Researchers are still working with this, but soon this process will be widespread.
W: That's fascinating. I didn't know that fibers could store heat. How does that work？
M: These fibers work with the heat by rearranging their structures.
W: That's truly unbelievable. You said that it'll be a decade before this type of clothes will be available. What a shame! I don't think I can wait that long.
What's the man's first reaction to what the woman describes？
A．He is shocked.
B．He is excited.
C．He is upset.
D．He is doubtful.

W: I recently read that in ten years we'll be wearing clothes that change with the weather. So when it's cold, our clothes will warm up, and when it's hot, our clothes will cool off.
M: Oh, very funny! So we'll be wearing huge clothes with built-in air conditioners and heaters.
W: I'm being serious! Researchers have discovered a method of treating fibers with plastic crystals capable of storing and releasing heat as the temperature fluctuates. These treated fibers absorb more heat than untreated fibers. Researchers are still working with this, but soon this process will be widespread.
M: That's fascinating. I didn't know that fibers had the capability of storing heat. How does that work？
W: These fibers work with the heat by rearranging their structures. The treated fibers move back and forth between two solid shapes.
M: I don't understand. What kind of shapes do they change into？
W: When the weather gets warmer, the crystals take on cube shapes and absorb heat. When the weather gets cooler, the crystals become cooler and come back to their original structure.
M: That's truly unbelievable. You said that it'd be a decade before this type of clothes will be available, What a shame! I don't think I can wait that long.
