听力原文：W: A great day, isn't it？
M: I guess so. But I feel awful because I watched TV until after midnight last night.
W: After midnight! Did you watch so late because you were bored？ I usually watch TV only ff I have nothing better to do.
M: Bored？ No, I was upset because I left my meal tickets in the cafeteria.
W: That worth more than fifty dollars. So, did watching TV make you feel better？
M: A bit. But after I turned the TV off, I just felt disgusted with myself for wasting so much time.
W: I've had that feeling before.
M: I had intended to watch just one program, but somehow I couldn't make myself switch off the TV.
W: Actually, I've read that there's a scientific explanation for that. It seems that there's a part of the brain that processes complex information, but that part becomes less active while watching TV.
M: That's certainly how I felt last night--like my brain wasn't very active.
W: That's not the worst of it. If you watch TV a lot, or for a long time, that part of the brain--the part that processes complex information, shows lowered activity and you become more and more passive.
M: That's incredible.
W: Next time you feel upset, you should go swimming. That's what I do, and it always makes me feel better.
M: I suppose. Now I've got to go to the cafeteria and get some more meal tickets.
(23)
A．When she's bored.
B．When there is a good program on.
C．After midnight.
D．After swimming.

Some brains do deteriorate with age. Alzheimer's disease, for example, strikes 13 percent of Americans 65 and older. But for most aging adults, the authors say, much of what occurs is a gradually widening focus of attention that makes it more difficult to latch onto just one fact, like a name or a telephone number. Although that can be frustrating, it is often useful. "It may be that distractibility is not, in fact, a bad thing," said Shelley H. Carson, a psychology researcher at Harvard whose work was cited in the book. "It may increase the amount of information available to the conscious mind. "
For example, in studies where subjects are asked to read passages that are interrupted with unexpected words or phrases, adults 60 and older work much more slowly than college students. Although the students plow through the texts at a consistent speed regardless of what the out-of-place words mean, older people slow down even more when the words are related to the topic at hand. That indicates that they are not just stumbling over the extra information, but are taking it in and processing it. When both groups were later asked questions for which the out-of-place words might be answers, the older adults responded much better than the students.
"For the young people, it's as if the distraction never happened," said an author of the review, Lynn Hasher, a professor of psychology at the University of Toronto and a senior scientist at the Rotman Research Institute. "But for older adults, because they've retained all this extra data, they' re now suddenly the better problem solvers. They can transfer the information they've soaked up from one situation to another. "
Such tendencies can yield big advantages in the real world, where it is not always clear what information is important, or will become important. A seemingly irrelevant point or suggestion in a memo can take on new meaning if the original plan changes. Or extra details that stole your attention, like others'yawning and fidgeting, may help you assess the speaker's real impact.
From the first two paragraphs, we learn that______.
A．aging brains tend to process more information simultaneously
B．one becomes forgetful when he gets old
C．older people don't think their brainpower is declining
D．the aged always stress long-term benefit
