Taste is such a subjective matter that we don’t usually conduct preference tests for food. The most you can say about anyone’s preference, is that it’s one person’s opinion. But because the two big cola companies—Coca-Cola and Pepsi Cola--- are marketed so aggressively, we’ve wondered how big a role taste preference actually plays in brand loyalty. We set up a taste test that challenged people who identified themselves as either Coca-Cola or Pepsi fans: Find your brand in a blind tasting.
We invited staff volunteers who had a strong liking for either Coca-Cola Classic (传统型) or Pepsi, Diet (低糖的) Coke, or Diet Pepsi. These were people who thought they’d have no trouble telling their brand from the other brand.
We eventually located 19 regular cola drinkers and 27 diet cola drinkers. Then we fed them four unidentified samples of cola one at a time, regular colas for the one group, diet versions for the other. We asked them to tell us whether each sample was Coke or Pepsi; then we analyzed the records statistically to compare the participants’ choices with what mere guess-work could have accomplished.
Getting all four samples right was a tough test, but not too tough, we thought, for people who believed they could recognize their brand. In the end, only 7 out of 19 regular cola drinkers correctly identified their brand of choice in all four trials. The diet-cola drinkers did a little worse-only 7 of 27 identified all four samples correctly.
Both groups did better than chance would predict,but nearly half the participants in each group made the wrong choice two or more times. Two people go all four samples wrong. Overall, half the participants did about as well on the last round of tasting as on the first, so tiredness, or taste burnout, was not a factor. Our preference test results suggest that only a few Pepsi participants and Coke fans may really be able to tell their favorite brand by taste and price.

No satisfactory way exists to explain how to form a good idea. You think about a problem until you're tired, forget it, maybe sleep on it, and then flash! When you aren't thinking about it, suddenly the answer arrives as a gift from the gods.
Of course, all ideas don't occur like that but so many do, particularly the most important ones. They burst into the mind, glowing with the heat of creation. How they do it is a mystery but they must come from somewhere. Let's assume they come from the "unconscious." This is reasonable, for psychologists use this term to describe mental processes which are unknown to the individual. Creative thought depends on what was unknown becoming known.
All of us have experienced this sudden arrival of a new idea, but it is easiest to examine it in the great creative personalities, many of whom experienced it in an intensified form and have written it down in their life stories and letters. One can draw examples from genius in any field, from religion, philosophy, and literature to art and music, even in mathematics, science, and technical invention, although these are often thought to depend only on logic and experiment. All truly creative activities depend in some degree on these signals from the unconscious, and the more highly insightful the person is, the sharper and more dramatic the signals become.
A type of creative experience is illustrated by the dreams which came to Descartes at the age of twenty-three and determined his life path. Descartes had unsuccessfully searched for certainty, first in the world of books, and then in the world of men. Then in a dream on November 10, 1619, he made the significant discovery that he could only find certainty in his own thoughts, cogito ergo sum ("I think; therefore, I exist"). This dream filled him with intense religious enthusiasm.
Descartes' experience is representative of countless others in every field of culture. The unconscious is certainly the source of instinctive activity. But in creative thought the unconscious is responsible for the production of new organized forms from relatively disorganized elements.Good ideas come from ________according to the writer.
| A．the unconscious | B．creative activities | C．dreams | D．logic and experiments |
The underlined word “these” (paragraph 3) probably refers to __________.
| A．philosophy, music, mathematics and science |
| B．religion, philosophy, literature, art and music |
| C．mathematics, science, and technical invention |
| D．both B and C |
What point can we see in the example of Descartes ?
| A．Dreams are the sources of instinctive activities. |
| B．Dreams sometimes contribute to important discoveries. |
| C．Geniuses have creative thoughts in their dreams. |
| D．Important discoveries are always made in dreams. |
The best title for this passage may be __________.
| A．The Unknown Becoming Known | B．The Role of Dreams |
| C．The Unconscious and Creative Activities | D．Birth of Bright Ideas |
NOT all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive experiences in nightmares.
Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly wipe out, the effect of painful memories.
In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are wiped out. They are not sure to what degree people's memories are affected.
The research has caused a great deal of argument. Some think it is a bad idea, while others support it.
Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war. They say that there are many people who suffer from terrible memories. “Some memories can ruin people's lives. They come back to you when you don't want to have them in a daydream or nightmare. They usually come with very painful emotions,” said Roger Pitman, a professor of psychiatry at Harvard Medical School. “This could relieve a lot of that suffering.”
But those who are against the research say that maybe the pills can change people's memories and changing memories is very dangerous because memories give us our identity. They also help us all avoid the mistakes of the past.
“All of us can think of bad events in our lives that were terrible at the time but make us who we are. I'm not sure we want to wipe those memories out,” said Rebecca Dresser, a medical ethicist.The passage is mainly about.
| A．a new medical invention |
| B．a new research on the pill |
| C．a way of wiping out painful memories |
| D．an argument about the research on the pill |
The drug tested on people can.
| A．cause the brain to fix memories |
| B．stop people remembering bad experiences |
| C．prevent body producing certain chemicals |
| D．wipe out the emotional effects of memories |
We can infer from the passage that.
| A．experts are not sure about the effects of the pills |
| B．the pill will certainly stop people's emotional memories |
| C．taking the pill will do harm to people's physical health |
| D．the pill has already been produced and used by the American public |
Which of the following does Rebecca Dresser agree with in the last paragraph?
| A．Some memories can ruin people's lives. |
| B．People want to get rid of bad memories. |
| C．Experiencing bad events makes us different from others. |
| D．The pill will reduce people's sufferings from bad memories. |

A woman named Emily renewing her driver’s license at the County Clerk’s office was asked to state her occupation. She hesitated, uncertain how to classify herself.
“What I mean is,” explained the recorder, “do you have a job, or are you just a …”
“Of course I have a job,” said Emily. “I’m a mother.”
“We don’t list ‘mother’ as an occupation… ‘housewife’ covers it,” said the recorder.
One day I found myself in the same situation. The clerk was obviously a career woman, confident and possessed of a high sounding title. “What is your occupation?” she asked.
The words simply popped out. “I’m a Research Associate in the field of Child Development and Human Relations.”
The clerk paused, ballpoint pen frozen in midair.
I repeated the title slowly, then I stared with wonder as my statement was written in bold, black ink on the official questionnaire.
“Might I ask,” said the clerk with new interest, “Just what you do in this field?”
Coolly, without any trace of panic in my voice, I heard myself reply, “I have a continuing program of research (what mother doesn’t), in the lab and in the field (normally I would have said indoors and out). Of course, the job is one of the most demanding in the humanities (any mother care to disagree?), and I often work 14 hours a day (24 is more like it). But the job is more challenging than most careers and rewards are more of a satisfaction rather than just money.”
There was an increasing note of respect in the clerk’s voice as she completed the form, stood up, and showed me out.
As I drove into our driveway, buoyed up (受鼓舞) by my glamorous new career, I was greeted by my lab assistants---ages 13, 7, and 3.
Upstairs I could hear our new experimental model (a 6 month old baby), in the child-development program, testing out a new vocal pattern.
I felt proud! I had gone on the official records as someone more distinguished and indispensable (不可缺少的) to mankind than “just another mother.”
Motherhood…What a glorious career! Especially when there’s a title on the door. What can we infer from the conversation between the woman and the recorder at the beginning of the passage?

| B．The woman felt ashamed to admit what her job was. |
| C．The author was upset about the situation that mothers faced. |
| D．Motherhood was not recognized and respected as a job by society. |
How did the female clerk feel at first when the author told her occupation?
| A．curious | B．indifferent | C．puzzled | D．interested |
Why did the woman clerk show more respect for the author?
| A．Because the author cared little about rewards. |
| B．Because she thought the author did admirable work. |
| C．Because she admired the author’s research work in the lab. |
| D．Because the writer did something she had little knowledge of. |
What is the author’s purpose of writing the passage?
| A．To show how you describe your job affects your feelings toward it. |
| B．To argue that motherhood is a worthy career and deserves respect. |
| C．To show that the author had a greater job than Emily. |
| D．To show that being a mother is hard and boring work. |
When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure—and so soon—that another ant is dead.
One scientist recently came up with a way to explain this ant behaviour. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I'm dead—take me away” when it is dead.
But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet” when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait I'm not dead yet” quickly goes away. When other ants detect the “dead” chemical without the “not dead yet” chemical, they move away the body.
To test his theory , Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the “Wait—I'm not dead yet” chemical, other ants left the treated ant alone. Choe believes this behavior shows that the “not dead yet” chemical overrides the “dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining “dead” chemical and remove the body from the nest.
Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.What is the function of the first paragraph?
