If you do not use your arms or legs for some time, they become weak; when you start using again, they slowly become strong again. Everybody knows this , and nobody would think of questioning the fact. 1. When someone says that he has a good memory, he really means that he keeps his memory in practice by exercising it regularly, either consciously or unconsciously. When someone else says that his memory is poor , he really means that he does not give it enough opportunity to become strong. 2. One of them exercises his arms and legs by playing tennis, while the other sits in a chair or motor car all day.
If a friend complains that his arms are weak, we know that it is his own fault. 3. , many of us think that his parents are to blame, or that he is just unlucky, and few of us realize that it is just his own fault. Not all of us can become extremely strong or extremely clever; but all of us can, if we have ordinary bodies and brains, improve our strength and our memory by the same means—practice.
Have you ever noticed that people who cannot read or write usually have better memories than those who can? 4. Of course, because those who cannot read or write have to remember things; they cannot write them down in a little notebook. They have to remember dates, time and prices, names, songs and stories; so their memory is the whole time being exercised.
5. ，learn from the poor：practice remembering.
A. What do you think of it ?
B. Yet many people do not seem to know that the memory works in the same way.
C. But if he tells us that he has a poor memory
D. So if you want a good memory
E. When someone else says that he is poor in the health
F. Why is this ?
G. The position is exactly the same as that of two people.

In the computer age, most of us take a broadband Internet connection for granted. Whether cable or mobile broadband, today’s connections are many times faster than those in the early days. Videos play smoothly, complex websites load quickly, and files download much faster than ten years ago. And the files are much bigger too.
There’s a catch, of course. You have to live near enough to a major city to get broadband Internet. If you don’t, it’s slow dial-up access for you. And for those living really far out, there may be no Internet access at all.
Technology experts often talk about the “last mile” problem, which refers to the difficulty of bringing Internet access to remote locations. In cities and suburbs, it’s relatively easy to provide access for everyone. It is much more difficult to deliver access to those living far from cities, especially in developing countries. Internet service providers, for their part, have been reluctant to provide access to sparsely(稀疏地) populated areas. The handful of Internet users they would reach wouldn’t cover the expense.
But every year, technological advancements allow of more and more Internet users. Most broadband connections today run over existing cable TV and telephone lines although these technologies aren’t available everywhere. Some companies have delivered the Internet over standard power lines. Advancements in cheaper, more efficient fiber optics cables(光纤电缆) promise to bring extremely fast Internet connections to more users.
Still, the “last mile” problem remains hard to deal with. There will always be somewhere that doesn’t have an affordable broadband connection. But someday that might not matter. If the rapid progress in cell phone technology is any indication(迹象), it may not be too long before an Internet connection simply follows you wherever you go.
1.The underlined part “ a catch” (in Paragraph 2) probably means “________”.
A. a rare challenge B. a desirable plan
C. an efficient device D. a hidden problem
2.What can we know from the third paragraph?
A. Internet connection has not been popular in most cities.
B. Internet service providers care about rural customers.
C. Computer is popular in developing countries.
D. It is hard to bring Internet access to users in remote areas.
3. Paragraph 4 mainly tells us that technological advancements ________.
A. make TV and telephone available everywhere
B. bring great change to people’s everyday life
C. make it possible for more people to use the Internet
D. bring faster Internet connections to users
4.What may eventually settle the “last mile” problem?
A. The broadband connection’s getting faster.
B. More and more Internet users.
C. More and more Internet connections.
D. The rapid progress in cell phone technology.

If you do not use your arms or your legs for some time, they become weak. When you start using them again, they slowly become strong again. Everybody knows this. Yet there are many people who do not seem to know that one’s memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by exercising it regularly. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong.
If a friend complains that his arms are weak, we know that it is his own fault. But if he tells us that he has a poor memory, many of us think that his parents are to blame, or that he is just unlucky, and few of us realize that it is really his own fault. Not all of us can become very strong or very clever, but all of us can improve our memory by the same means — practice.
Have you ever noticed that people who cannot read or write usually have a better memory than those who can? Why is this? Of course, because people who can’t read or write have to remember things: they cannot write them down in a little notebook. They have to remember dates, prices, names, songs and stories, so their memory is exercised all the time.
So if you want a good memory, learn from those who cannot read or write: practice remembering.
