【題目】

What makes humans smarter than other animals? We’ve got a bigger brain, of course. But when it comes to brains, is bigger always better?

Traditionally, scientists have thought that humans’ better intelligence(智慧)came mostly from the fact that our brains are three times bigger than those of our nearest living relatives, chimpanzees. People even used to believe that men are smarter than women because men have a little larger brains.

This, however, is not the truth. Scientists at University College London in the UK have found that brain organization, and not brain size, is the key to the advantage of human intelligence, reported Live Science.

Through millions of years of gradual development, our ancestors(祖先)were pushed to get smarter all the time so that they could meet the needs of new environments. However, holding this growing intelligence in increasingly large brains was not the best choice because bigger brains require more energy to power. “This is when reorganization may come into play,” said Christophe Soligo, a member of the London research team.

In the study, scientists looked at the brains of 17 kinds of primates(靈長目動物), including monkeys, apes and humans. They found that in the process of gradual development, brains didn’t keep growing as a whole. Certain parts of the brain grew more than others as needed, and in this way they could make the best use of their limited brain space.

For example, when early humans were trying hard to live, the brain region(區(qū)域) which is in charge of using tools and finding food grew in size more than other regions. But in modern times, the prefrontal cortex(前額皮質(zhì))— the region in charge of social cognition (認(rèn)知), moral judgments and goal-directed planning — grew more than the rest of the brain.

Think of the brain as a room. If a big room is poorly organized, it doesn’t necessarily store more things than a smaller one.

Paul Manger, a professor, explains this using the example of whales. He told Scientific American: “Whales have big brains. But if you look at the actual structure(結(jié)構(gòu))of the brain, it’s very simple. Brain size only matters if the rest of the brain is organized properly. ”

1According to the passage, in recent human development, ________.

A.the prefrontal cortex grew most in the brain

B.human’s most regions of the brain didn’t change

C.brain became simple because the brain space is limited

D.brain kept growing in size todeal with new environments

2The words “in charge of” in Paragraph 6 probably mean “________”.

A.similar toB.responsible forC.in need ofD.with help of

3The writer probably agrees that ________.

A.the difference between men and women has an effect on intelligence

B.the larger brains are usually organized better than the smaller ones

C.animals whose brains are organized properly can be smarter

D.the size of the brain has nothing to do with intelligence

4Which of the following would be the best title for the passage?

A.Is Human Brain the Biggest of All Animals’?B.Do Men have bigger Brains than Women?

C.Are Human Brains Growing as a Whole?D.Does a Bigger Brain Make you Smarter?

【題目】閱讀理解。

It was a Christmas night. I was an unlucky nurse who had to work on such a beautiful festival. When I was complaining(抱怨)about it, three people appeared at my desk — a tired woman and two children.

“Are you all sick?” I asked doubtfully because they seemed all right.

“Yes,” the woman answered weakly and lowered her head.

But when they started to present their problems, things became unclear. One child had a fever, but his temperature was OK. The other child had an earache, but she could not tell me which ear hurt. It seemed that the mother was pretending(假裝)to cough.

Something was wrong. But I only explained that it might take a while before a doctor could meet them. “Take your time, please,” said the mother. I checked their charts — no address. Suddenly I knew, they were homeless while the hospital was warm.

The family huddled(蜷縮)together under the Christmas tree, smiling and talking with each other sweetly. Quietly, I went back to the nurses’ station and told them what happened in the waiting room. It was just like God sending us a gift on Christmas Day. The nurses’ station suddenly came back to life. All the nurses went into action for “a Christmas emergency(急診)”.

We took out our meals for our Christmas “patients”. We also put together oranges and apples as presents. We tried to exceed the needs of a family who only wanted a warm place on Christmas night. Later, the little girl kissed me and said, “Thanks for being our angel(天使).”

A.proud B.unhappy C.pleased

A.they came to visit a patient

A.降低 B.超出 C.拒絕
