Exercising Your Memory
1. Aging does not mean a dramatic decline in memory power,unless you help it happen by letting your mind go.
2. That's not to say that memory doesn't change throughout life.Researchers divide memory into categories based on the length of time when memories are stored.One system divides it up as short-term(less than one minute;remembering a telephone number while you dial,for in-stance),long-term(over a period of years)and very long-term memory(over a lifetime).
3. Short-term memory isn't mastered until about age 7,but after that you never lose it. Long-term memory,however,involves more effort and skill and changes more through life.It's not until the early teens（十几岁）that most people develop a mature long-term memory.
4. First,we must get information into our heads through learning.Learning strategies can get rusty（生锈）without constant use. High school and college students,who are forced to repeated-ly exercise their long-term memory abilities(at least long enough to get them through a final ex- am),usually do well on memory tests.The longer you stay in school,the more chance you get to polish your learning skills.It's no wonder that more highly educated people have more effective memory skills throughout life.
5. Although older people in general learn somewhat more slowly than they did when younger,a dramatic difference exists between those who stay intellectually active—reading,discussing,tak- ing classes, thinking—and those who do not. Giving the brain daily workout（锻炼）is just as important as exercising your muscles.Brainwork keeps your learning strategies in shape,and this helps your memory to function at full capacity.
6.The next part of a healthy long-term memory is retention(记忆力）,the ability to store what you have learned.Memory researchers still do not know whether memories are los—whether they still exist in the brain but our mental searching cannot turn them up,or have disappeared entirely as our brain ages.
7. The third necessity for memory is recall,the ability to bring to mind the memories we have stored .Again,while aging has widely different effects on the recall abilities of different people, research indicates that the older we get,the longer it takes to recall facts.But slower recall is still recall.In fact,aging does not seem to have any effect on forgetting at all,which takes place at the same rate in younger and older people.
Retention refers to________.
A.for younger and older people
B.to the proper function of your memory
C.is called long-term memory
D.the capacity to store what you have learned
E.belongs to very long-term memory
F.the ability to remain mentally healthy

Why Money Doesn’t Buy Happiness
What do the experts say
All in all, it
was probably a mistake to look for the answer to the eternal question--"Does
money buy happiness "--from people who practice what’s called the gloomy
science. For when economists tackled the question, they started from the
observation that when people put something up for sale they try to get as much
for it as they can, and when people buy something they try to pay as little for
it as they can. Both sides in the transaction, the economists noticed, are
therefore behaving as if they would be more satisfied, or happier, dare we say,
if they ended up receiving more money (the seller) or holding on to more money
(the buyer). Hence, more money must be better than less, and the only way more
of something can be bet
A. are taken for granted by the new generation
B. are soon replaced by new ones
C. produce expanding aspirations
D. free the well-off people from housework
