When you say that someone has a good memory, ...

When you say that someone has a good memory, what exactly do you mean? Are you saying that the person has fast recall or that he or she ______ information quickly? Or maybe you just mean that the person remembers a lot about her or his childhood. The truth is that it is ______ to say exactly what memory is. Even scientists who have been studying memory for decades say they are still trying to ______ exactly what it is. But we do know that a particular memory is not just one thing stored somewhere in the brain. ______ , a memory is made up of bits and pieces of information stored all over the brain. Perhaps the best way to ______ memory is to say that it is a process-a process of recording, storing, and getting back information. Practice and repetition can help to ______ the pieces that make up our memory of that information.

Memory can be negatively affected by a number of things. ______　 nutrition can affect a person’s ability to store information. Excessive alcohol use can also ______ memory and cause permanent ______ to the brain over the long term. A vision or hearing problem may affect a person’s ability to notice certain things, thus making it ______ to register information in the brain.

When people talk about memory, they often ______ both short-term memory and long-term memory. If you want to call a store or an office that you don’t call often, you look in the telephone book for the number. You dial the number, and then you forget it! You use your short-term memory to remember the number. Your short-term memory lasts about 30 seconds, or half a minute. ______ , you don’t need to look in the telephone book for your best friend’s number, because you already know it. This number is in your long-term memory, which ______ information about things you have learned and experienced through the years.

Why do you forget things sometimes? The major reason for forgetting something is that you did not learn it well enough ______. For example, if you meet some new people and right away forget their names, it is because you did not ______ the names at the first few seconds when you heard them.

If we were asked exactly what we were doing a year ago，we should probably have to say that we could not remember. But if we had kept a book and had written in it an account of what we did each day，we should be able to give an answer to the question.

It is the same in history. Many things have been forgotten because we do not have any written account of them. Sometimes men did keep a record of the most important happenings in their country，but often it was destroyed by fire or in a war．Sometimes there was never any written record at all because the people of that time and place did not know how to write．For example，we know a good deal about the people who lived in China 4，000 years ago, because they could write and leave written records for those who lived after them．But we know almost nothing about the people who lived even 200 years ago in central Africa, because they had not learned to write．

Sometimes,of course，even if the people cannot write，they may know something of the past．They have heard about it from older people，and often songs and dances and stories have been made about the most important happenings，and these have been sung and acted and told for many generations .For most people are proud to tell what their fathers did in the past．This we may call ’remembered history’．Some of it has now been written down. It is not so exact or so valuable to us as written history is，because words are much more easily changed when used again and again in speech than when copied in writing．But where there are no written records，such spoken stories are often very helpful．

1.．We know very little about the central Africa 200 years ago because ___

2.．“Remembered history”refers to ___．

3.．“Remembered history”is regarded as valuable only when ____.

4. .The passage suggests that we could have learned much more about our past than we do now if the ancient people had _____

These days when someone says a computer has a bug in it, usually they mean that there's a problem with one of its programs. Maybe your computer has crashed when you are in the middle of a game, or you get an error message when you try to go to a website.

But back in the early days of computers, a woman named Grace Hopper was part of the tear that discovered the very first computer bug.

Hopper was a mathematician. She'd been hired by the navy to help program the new Mark II computer. The Mark Ⅱ’s job was to quickly solve the math problems ships and airplanes used to find in their way. The MarkⅡ worked by reading instructions from a long strip of paper with holes in it. The computer translated the patterns of holes into the math problems it was supposed to solve.

One afternoon in 1947 Hopper and her team were running a program. But the computer wasn’t giving them the right results. What could be wrong? They finally ended up taking the Mark II apart, looking for problems. What did they find?

It was a dead moth(蛀虫)! The moth was blocking some of the holes on the paper strip—no wonder the computer didn't know what to do.

Hopper knew that the term "bug" had been used before when there were problems with machines. But this was the first time a computer had ever had one. She thought it was funny that it was a real bug. Some people think Hopper was the first person to use the word "debug" to mean “get rid of the problems in a computer”.

Her team kept a logbook of everything they did. They taped the moth onto the page for that day. The logbook, moth and all, is now in the Smithsonian Museum of American History in Washington D.C.

Grace Hopper worked with computers her whole life. She was the first person to write a word-based computer language. This makes it easier for people to tell computers what to do. Some people called her "Grandma COBOL" after one of the computer languages she helped develop. But to most she was just “Amazing Grace”.

1.What's the writer's purpose in writing paragraph 1?

A. To tell us the main idea of the passage.

B. To arouse the readers' interest to read on.

C. To show the structure of the passage.

D. To give a description of what a bug is.

2.Which of the followings is true to describe Grace Hopper?

A. She was the first expert to use the term “bug”.

B. She was an astronomer to help work on the Mark II.

C. She devoted all her life to work related to computers.

D. She kept a record of all the computers on the Mark II.

3.What is the text mainly about?

A. The history of bug. B. The discovery of the first bug.

C. Grace Hopper and her bug. D. Grace Hopper and the Mark II.

What do you remember about your childhood? I have good memories of exploring(探测) the fields near my house and riding my bike around the park. Today, children don’t spend enough time in the fresh air. Many of them fix their eyes on a screen either on a computer, or a TV ---they seem to be living in a virtual world. They have lost touch with nature.

Now 400 organizations in the UK are encouraging children to have some “wild time”. They want kids to exchange at least 30 minutes of watching TV or playing computer games for time playing outside. The simple pleasures of exploring and discovering nature help children to learn and keep fit too. Andy Simpson, who is part of the campaign(倡议活动), says: “An extra 30 minutes of wild time every day for all under 12-year-olds in the UK would be the equivalent(同等) of just three months of their childhood spent outdoors.” Even if the kids live in a city, they can go on adventures in the garden or the park. However, children often need a helping hand from Mum and Dad. They need to be shown what to do and where to go.

So despite(尽管) the complex(复杂的) world that young people grow up in now, it seems that going back to basics and experiencing “nature’s playground ” is what modern children need. Andy Simpson adds: “We want parents to see what this magical “playground” does for their kids’ development , independence and creativity(创造力) , by giving wild time a go ” . David Bond from Project Wild Thing says, “We need to make more space for wild time in children’s daily routine, freeing this generation of kids to have the sort of experiences that many of us took for granted. ”

1.What does the author think about the present kids?

A. They depend on their parents too much.

B. They’re eager to play with their parents.

C. They spend too much time playing outside.

D. They don’t get close to nature.

2.In the first paragraph, the underlined word “virtual ” probably　 refers to ______________ .

A. magical　　 　　 B. perfect　　 　　 C. unreal　　 　　 D. wonderful

3.What suggestion does David Bond give us?

A. Prevent kids from playing computer games.

B. Help children master basic skills.

C. Teach kids how to face difficulties.

D. Let children have more wild time.

4.What do we know about the author?

A. He disliked his childhood full of study and exams.

B. He had a happy childhood by exploring the outdoors.

C. He often went to school by riding on a bicycle.

D. He showed a great interest in watching TV.
