A constantly doing memory work
B making frequent adjustments
C going through specific training
D taking part in various mental activities
注：考第三段末句。
Many experts are so convinced of the benefits of challenging the brain that they are putting the theory to work in their own lives. The idea is not necessarily to learn to memorize enormous amounts of information, says James Fozard, associate director of the National Institute on Aging. Most of us dont need that kind of skill. Such specific training is of less interest than being able to maintain mental alertness. Fozard and others say they challenge their brains with different mental skills, both because they enjoy them and because they are sure that their range of activities will help the way their brains work.
23. The findings of James and other scientists in their work _________.
A remain a theory to be further proved
B have been challenged by many other experts
C are practised by the researchers themselves
D have been generally accepted
注：第三段首句中的theory等同于findings。

Dear Mary,
You said in your letter that many of your classmates wore fashionableclothes, but you couldn't afford them so you felt very depressed. There are dif-ferent views on people's clothes. The followings are my ideas:
Firstly, you shouldn't put too much emphasis on physical appearance.
Remember that the most important task for you today is to concentrate on yourstudies. No matter what you wear, you will really look your best when youcome out first in your examinations.
Secondly, you should understand that it is a fine virtue to live in fru-gality. Just as a famous saying goes, Frugality is the mother of virtue.
Since your family can't provide you with enough money to buy fashionableclothes, it is all the more necessary for you to try to lighten the financialburden of your family. And you will find the virtue of frugality benefit youa lot in your future life.
I hope you understand what I mean. Hope you will take a positive attitudetowards life and will be happy again when you read my letter.
Yours,
Anne

Dear all,
I am writing this letter to express my gratitude to my parents for teaching me to be positive and to be strong. “Educating the mind without educating the heart is no education at all.” is the opinion held by Aristotle. It is the experience of our forefathers, however, it is correct even today, including my parenting.
It is widely acknowledged that parenting, which can also be explained as family education, is of great significance in our character forming and manner acquiring. To be more detailed, setting good examples instead of just giving precepts is the greatest achievement of my parents. They not only taught me to think for the best and prepare for the worst; they taught me how. They not only told me the benefits of being strong in mind; they proved it. All those things require huge amount of time and work, but it’s worth it.
Without my parents’ contribution and education, I would never be who I am now. But most importantly, I would never be more gratitude to them than today.
Yours,
XXX
