"What's the name of our neighbor? I can't remember right now. " Have you ever heard your grandparents ask questions like this sometimes? Usually, we think that older people's memory becomes bad because their brains get weak. But now a team of scientists at the University of Tubingen in Germany has a new idea.[

"The human brain works slower in old age，" says Michael Ramscar, the lead scientist. "But only because they have stored more information overtime. "

The findings are based on a series of computer simulations(模拟)of learning and memory. Scientists let the computers read a certain amount of words and learn new things each day. When the computer "reads" only so much, its performance on cognitive(认知)tests is similar of a young adult. But if the computer learns the experiences we might encounter over a lifetime, its performance is similar to that of an older adult.

Often it is slower, but not because its processing capacity has declined. Rather, increased "experience" has caused the computer's database to grow, giving it more data(数据)to process-which takes time. This is similar to old people. Imagine a person knows two people's birthdays. Another person knows the birthdays of 2000 people, but can only match the right person to the right birthday nine times out of 10. Can you say the first person has a better memory than the second person?

1.The writer uses a question at the beginning of the passage to 　　　　　 .

A. invite the readers to answer the question

B. attract the readers' attention to the topic

C. show how weak older people's brains are

D. tell the readers the latest findings about brains

2.According to the research, why do old people forget people's names easily?

A. Because they have a very poor memory.

B. Because they are too old to remember things.

C. Because their brains become weaker than before.

D. Because they have stored too much information.

3.Where would this passage most probably appear?

A. In a magazine.　　 B. In a story book.

C. In an ad.　　　　　 D. In a guidebook.

4.What would be the best title for the passage?

A. Do old people have a bad memory?

B. Scientists' new findings on brains

C. Human brain's processing capacity

D. Which is better, the old or the young?

“What's the name of our neighbor? I can't remember right now.”Have you ever heard your grandparents ask questions like this? Usually, we think older people's memories become bad because their brains get weak. But a team of scientists at the University of Tubingen in Germany has a different idea.

“The human brain works slower in old age,” said lead scientist Michael Ramscar, “but only because they have stored more information over time.”

The findings are based on a series of computer simulations（模拟） of learning and memory.

Scientist let the computers read a certain amount of words and learn new things each day. When the computer “reads”only so much, its performance on cognitive（ 认知） tests is similar of a young adult. But if the computer learned the experiences we might encounter（经历） over a lifetime, its perfection is similar to that of an older adult.

Often it was slower because increased“experience” had caused the computer 's database（数据库） to grow, giving it more data to process - which takes time. This is similar to old people.

Imagine a person knows two people's birthdays. Another person knows the birthdays of 2,000 people, but can only match the right person to the right birthday nine times out of 10. Can you say the first person has a better memory than the second person? The basic idea is that“The larger the library you have in your head, the longer it usually takes to find a particular word,” Benedict Carey, a science reporter for The New York Times, wrote in an article about the study.

1.The writer uses a question at the beginning to________.

A.encourage readers to think of their neighbors

2.How did the scientists do their research?

D.They followed the experiences of a group of old people

3.According to the research, why do old people forget other people's names easily?

A.Because they have a very poor memory

B.Because they are too old to remember things

C.Because their brains become weaker over time

D.Because there is too much information in their brains

4.What does the underlined word“similar”in the passage mean in Chinese?

A.协调的 B.相似的 C.奇怪的 D.迥异的

You may not know the name of your neighbor’s dog though you see it every day. But you may know the name of this cute white dog with black ears. The dog is 63 years old this year.

He is Snoopy, the main character in the US Peanuts comic strip (《花生》连环画). In the comic, Snoopy has done lots of jobs. He has been a lawyer, a writer, and even the first astronaut on the moon.

Snoopy has his own dreams. He works hard to make them come true. For example, though people never like the stories he writes, Snoopy keeps writing because he wants to succeed one day. In Snoopy, people see the truth of the saying: “The only thing you can do when you fail is not giving up（放弃）.”

Snoopy never stops on his way to make his dreams come true. He teaches people to have the right idea about their lives.

Because of that, Snoopy has become popular in the US since his birth in 1950. Last year, American people chose Snoopy as the Top Dog in American Pop Culture.

Snoopy’s influence(影响) goes all around the world. Over the past 61 years, he has been in more than 2,600 newspapers in 75 countries. As a US newspaper once said: “If anyone can be a good influence in children and teenagers’ lives, it is Snoopy.”
