If you do not use your arms or your legs for some time, they will become weak, and when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that 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 using it. 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 says that his arms and legs 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 may be blamed, and few of us know that it is just his own fault (过错). Have you ever found that some people can't read or write but usually they have better memories? This is because they cannot read or write and when they have to remember things, they cannot write them down in a small notebook. As a result, they have to remember days, names, songs and stories, so their memory is being exercised the whole time.
So if you want to have a good memory, learn from the people: practice remembering things in a way as other people do.
【小题1】Someone can't have a good memory if ________.

Have you ever heard an echo of your voice?

An echo is a reflected(反射)sound. Stand in a very large, empty hall with nothing on the walls. Then shout. The sounds you make will hit the walls and come back to you. The walls reflect the sounds. These reflected sounds are called “echoes”.

We can use reflected sound to make sound travel farther. Hold a watch about fifty centimeters from your ear. You cannot hear it. The sound of the watch travels a short way in all directions. It does not travel as far as your ear. You can make it travel to your ear by using a roll of cardboard(纸板筒).

Make the roll of cardboard about fifty centimeters long. Put one end over your ear and hold the watch at the other. Now you can hear the watch because the sound has not gone in all directions. It is reflected down the roll to your ear.

A megaphone(喇叭筒)works in the same way. It makes sound travel farther. It reflects the sound into a beam which can travel a long way. In the ship, the sailor uses the megaphone to make his voice travel. Without the megaphone, his voice cannot travel far.

We use reflected sound in many ways. We use it to measure the depth of the sea, for example. Among the animals, bats and whales use reflected sound to tell them where they are and what things are near them.

1990 was a significant year in world enents. In Febbruary, Nelson Mandela was set free after 27 years in prison. In October, East and West Germany became one country again. Then at the end of 1990, the World Wide Web was born. For this final event we have one man to thank, Tim Berners-Lee, the father of the Web.

Berners-Lee was born on June 8, 1955 in London, England. His parents, both computer designers, encouraged him to think and work creativelhy as he grew up. He was an excellent student and naturally took an interest in computers and science.

After graduating from Oxford University, Tim went to work at a science research centre in Sfwitzerland. There be developed some of the different systems that would later become the Web. The first was HTML, the computer language used to make web pages. The second was an address system that let  computers anhywhere find each other and send and receive information. In 1990, while still at the science centre in Switzerland, he put them together to make the first Internet browser. It could run on any computer and allowed people to create  share their information with the rest of the world.

Tim knew that the more people used the Web, the more useful it would be. He wasn’t interested in money but knowledge, so he gave out his invention for free to anyone who was interested. Many were interested and the growth of the Internet began.

Today Tim works as a professor at the MIT in America, researching new and interesting ways to use the Web. He has received many awards from governments and organizations for his efforts. He is still not very interested in money. That is why he is so admired by his students and workmates. It may also be one of the reasons that few people outside the world of technology know his name.

1. The underlined word “significant” (in Paragraph 1) most probably means “       ” .

2.Which of the following statements is true according to the passage?

3. What can we learn about Berners-Lee from the passage?

4. Where does Berners-Lee live today?

If you do not use your arms or your legs for some time, they will become weak, when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that 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 using it. 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 says that his arms and legs 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 may be blamed(责备), and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories ? This is because they cannot read or write and they have to remember things, they cannot write them down in a small notebook. They have to remember days, names, songs and stories, so their memory is the whole time being exercised.

So if you want to have a good memory, learn from the people: practise remembering things in a way as other people do.
