"What's the name of our neighbour? 1 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（模擬）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（認(rèn)知）tests is similar to that of a young adult. But if the computer learned the experiences we might have over a lifetime, its performance is similar to that of an older adult.

Often it was slower because increased "experience" had caused the computer's database（數(shù)據(jù)庫(kù)）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, wrote in an article about the study.

1.Why did the writer use a question at the beginning?

A.To attract readers' attention to the topic.

B.To invite the readers to answer the question.

C.To prove that older people have bad memories.

D.To encourage readers to think of their neighbours.

2.How did the scientists do their research?

A.They interviewed all the old people of their neighbours.

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

C.They asked both young and old people the same questions.

D.They used computers to simulate human learning and memory.

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 than before.

D.Because they have too much information in their brains.

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

A.Is it Better to Be Old or Young B.Human Brain's Processing Ability.

C.Do Old People Have Poor Memories? D.Scientists' New Findings on Brains.

There are many useful inventions in the world. Do you want to have an umbrella that makes your hands free? Alan has invented the "Nubrella", which means "new umbrella". It is the first truly hand-free umbrella in the world.

One cool thing about the Nubrella is that you don't need to hold it like a usual umbrella, you can wear it. The shoulder straps（肩帶）of the Nubrella can hold the umbrella for you. The Nubrella is big enough to cover your whole head and your body. You don't need to worry about getting wet in the rain. So when walking in the rain with the Nubrella, you're able to use your cell phone or drink a cup of hot coffee.

The idea for the invention began on one rainy day. Alan was standing in his shop and found that it was hard to keep their umbrellas in the right place for the people. At that moment an idea came into his mind. He wanted to have an umbrella which could make a rainy day easy and fun.

Nowadays, Nubrella is on sale all over the world. The price of it is 59 dollars in America. You can also find it on Taobao. Would you like to have such kind of umbrella?

1.Is Nubrella only sold in America?

2.What does the word "Nubrella" mean?

3.How can Nubrella help our hands free?

4.Which one do you prefer to use, a Nubrella or a usual umbrella? Why?
