  Ask Dr ? Jeffers

This month Dr. Jeffers is answering questions about the human brain and how it works.

Dear Dr. Jeffers,

One of my colleagues, Felix Moeller, told me that scientists are learning to use computer to ‘read minds’. Is there any truth to this story/

Jane Leon, New York, USA

Dear Ms. Leon,

Well, a lot of research is being conducted in this area, but so far, the brain scanning equipment and corresponding computer programs haven’t been able to actually read thoughts. In one experiment, test subjects(受试者)were connected to scanning equipment and shown two numbers on a screen. They were then asked to choose between adding or subtracting(减)the two numbers. Using this method, researchers were able to follow brain processes and make the correct assumptions(假设)70 percent of the time. It’s not quite mind reading, but it’s certainly a first step.

—Dr. J.

Dear Dr. Jeffers,

My three-year-old son loves it when I dig my fingers into his sides and tickle (胳肢)him until he laughs uncontrollably. The other day I noticed him trying to tickle himself but he couldn’t do it. Why not?

Glenn Lewis, Vancouver, Canada

Dear Mr. Lewis,

It’s because of how the brain works. The brain is trained to know what to pay attention to and what to ignore. It causes us to ignore physical feelings we expect to happen, but it causes a mild panic reaction when there is an unexpected feeling. For example, you don’t notice how your shoulder feels while you’re walking down the street. But if someone comes up behind you and touches you lightly on the shoulder, you may jump in fear. It’s that unexpected part that causes the tickle reaction.

Dr. J.

46. What can we learn from the answer to the first question?                          

A. Some equipment is able to read human minds.

B. Some progress has been made in mind reading.

C. Test subjects have been used to make decisions.

D. Computer programs can copy brain processes.

47. People laugh when tickled by others because the feeling is _______.                 

A. unexpected        B. expected        C. comfortable        D. uncomfortable

48. Who has got a little child according to the text?                                  

A. Ms. Leon          B. Mr. Lewis        C. Mr. Moeller        D. Dr. Jeffers

49. According to the text, Jeffers is probably _______.                               

A. a computer programmer                B. a test subject

C. a human brain expert                   D. a medical doctor

But how many of us remember it being ___42___ at the time? How many of us remember the blind panic of the Monday morning maths test when the ___43___ we could hope for was a miracle(奇迹) to make the numbers we ___44___ without thinking as answers somehow ___45___ the questions?
On the face of it, today’s children can ___46___ be considered happier and more satisfied. They have a daily numeracy lesson ___47___ to improving their maths skills. But if that sounds like hell to you, you may ___48__ find that your child surprises you by actually quite ___49__ it.
One of the __50___ is that over the last ten years or so, there has been a ___51___ in the way maths is taught. And many of those who teach it feel it’s been a ___52__ for the better. There’s generally much more emphasis now on __53___ arithmetic, getting children used to doing calculations without forever having a pen in one hand and a calculator in the other. Often the first question a teacher will ask is: can you do this in your___54___? And if they can, they do.

Children are getting so fat that they may be the first generation to die before their parents, an expert says.

Today's young people will be affected by potential (潜在的) killers such as heart disease because of their weight. Fatty fast-food diets combined with the lifestyles with televisions and computers could mean kids will die young, says Professor Andrew Prentice, from the London School of Hygiene and Tropical Medicine. At the same time, the shape of the human body is going through a great change because adults are getting so fat.

Here in Britain, the latest research shows that the average waist size for a man is 36~38 inches and may be 42~44 inches by 2032.This compares with only 32.6 inches in 1972. Women's waists have grown from an average of 22 inches in the 1920s to 24 inches in the 1950s and 30 inches now. One of the major reasons why children now are at greater risk is that we are getting fatter younger. In the UK alone, more than one million under 16 years old are thought

to be overweight or fat—double the number in the 1980s. One in ten of four-year-olds are also medically said to be obese.

The obesity which started in the US, has now spread to Europe, Australia, Central America and the Middle East. Many nations now record more than 20 percent of their population as obese and well over half of the population as overweight.

Professor Prentice says the change in our shape has been caused by high-energy foods combined with a dramatic (急剧的) drop in the energy we use as a result of technology developments.

He is not alone in his concern. Only last week one medical magazine revealed how obesity was fuelling a rise in cancer cases. Obesity also increases the risk factor for heart disease and so on. An averagely obese person's lifespan (寿命) is shortened by around nine years while a seriously obese person by much more.

Professor Prentice says,

“So_will_parents_live_longer_than_their_children,_as_an_American_obesity_expert_said_recently?”

“The answer is yes—and no.” Yes, when most children become obese. No, because this is now becoming an alarmingly serious problem in the US. “Such children will have a greatly reduced quality of life on both body and mind.”

So say “No” to sandwiches and hamburgers.

1.From the second paragraph, we know that ________.

A.heart disease is caused by people's weight

B.bad living habits make children die young

C.increasing weight could kill young people

D.adults know how to change their shape of body

2.According to Professor Prentice, people become fatter because ________.

A.the energy people take in is more than they need

B.high technology makes people use less energy

C.food contains too much energy

D.people like to eat fast food

3.For the underlined question, the answer “no” suggests ________.

A.children should refuse fast-food diets

B.children's obesity is becoming more and more serious

C.Americans have realized the bad consequence of the obesity

D.the government should call on fat people to lose weight as soon as possible

完型填空(共20小题;每小题1分,满分20分)
阅读下面短文,从1---20各题所给的四个选项(A、B、C和D)中,选出最佳选项, 并在答题卡上将该选项标号涂黑。
One day, an expert in time-management was speaking to a group of business students. To make the point , he used an illustration.
As he stood in front of the group, he said, “Okay, time for a quiz.” He then pulled out a wide-mouth jar and set it on the table. Then he    2   placed about a dozen fist-sized rocks, one by one, into the jar.
When the jar was filled to the    3   and no more rocks would fit inside, he asked, “Is this jar    4 ?” Everyone in the class said, “Yes.”
“Really?” Then he    5  under the table and pulled out a bucket of gravel(沙砾,石子),dumped some in and   6  the jar, causing pieces of gravel to work themselves down into the space    7  the big rocks. Then he asked the group the same question. “Probably not.” One of them answered. “Good!” he replied.
He reached under the table and    8   a bucket of sand. He started dumping the sand in the jar and it went into all the    9   left between the rocks and the gravel.    10   he asked the question. “No!” the class shouted. “Good!” Then he grabbed a can of water and began to pour it in    11   the jar was filled to the brim.
Then the expert in time-management looked at the class and asked, “What is the    12  of this illustration?” It is such a seemingly easy question that one   13   student raised his hand and said, “It is, however full your schedule is, if you try really hard you can always   14   some more things in it.”
“No,” the speaker replied, “The truth it teaches us is that you will    15   get them in at all if you don’t put the big rocks in first.    16   the big rocks in your life are, do things that you love and    17  for yourself. In your schedule if you value the little stuff then you’ll fill your life with    18   things and you will never have the real quality time you need to spend on the big, important stuff. So, tonight, or in the morning, when you are   19   on this short story, ask yourself what are the ‘big rocks’ in your life? Then put those in your    20   first.”
