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 or Pepsi, Diet 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 with 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 guesswork 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 out 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 got 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.

According to the passage the preference test was conducted in order to ________.

A. show that a person’s opinion about taste is mere guesswork

B. compare the ability of the participants in choosing their drinks

C. find out the role taste preference plays in a person’s drinking

D. reveal which cola is more to the liking of the drinkers

The statistics recorded in the preference tests show that________.

A. there is not much difference in taste between Coca-Cola and Pepsi

B. few people had trouble telling Coca-Cola from Pepsi

C. people’s tastes differ from one another

D. Coca-Cola and Pepsi are people’s two most favorite drinks

The underlined word “burnout” here refers to the state of________.

A. being seriously burnt in the skin            

B. being badly damaged by fire   

C. being unable to burn for lack of fuel      

D. being unable to function because of too much use

The author’s purpose in writing this passage is to________.

A. emphasize that taste and price are closely related to each other

B. recommend that blind tasting be introduced in the quality control of colas

C. show that taste preference is highly subjective

D. argue that taste testing is an important marketing strategy

Are you worried by the rising crime rate? If you are, you probably know that your house, possessions(財產) and person are increasingly in danger of suffering from great rise in the cases of burglary(夜盜;搶劫) and attack.
Figures show an ever-increasing crime rate, but it is only too easy to imagine "It will never happen to me". Unfortunately, statistics show that it really can happen to you and, if you live in a large city, you run twice the risk of being a victim.

Everyone hates to wait in lines. We get that anxious feeling that our precious life is slipping away while we’re doing something so meaningless. But it’s not always the length of the wait we find so unbearable. Some people camp outside Apple stores for an entire night just to get their hands on the latest product. But waiting 10 minutes in a grocery store just to buy a drink? Forget it.

??? Our behavior when waiting is only partly decided by the length of the wait. “Often the psychology of queuing is more important than the statistics of the wait itself,” notes the MIT researcher Richard Larson.

??? One apparent aspect of queuing psychology is that we get bored when we wait in line. This issue is solved in many ways, from magazines in hospital waiting rooms to mirrors in elevators so that we can check our appearance.

??? We really hate it when we expect a short wait and then get a long one. But studies show that we are much more patient when we are given an idea of how long we’ll be waiting.

??? Walt Disney Co knows this better than anyone else. It posts estimated waiting times for attractions in its theme parks. But according to Larson, these times are overestimated so that visitors get to the front of the queue more quickly than they expect. It keeps them happy.

??? But perhaps the biggest influence on our feelings about waiting in a line has to do with our sense of fairness. When it comes to queues, the universally acknowledged standard is first come, first served. Any departure from this principle is regarded as unfair and can lead to violent queue anger.

You’ve probably experienced mild queue anger yourself in fast food restaurants, watching people in the other line zoom ahead of you, cursing yourself for having chosen the “wrong” line. In order to solve this problem, the serpentine(蛇形) line was invented. The serpentine line guides all customers into one big snaking queue, separated by ropes or barriers. When you reach the head of the queue, you are directed to the next available server, or teller, or customs official. The serpentine line isn’t always faster than multi-lines before an array() of cash registers. But it offers important comfort: you absolutely never have to see someone arrive after you and get served before you.

In life, waiting is inevitable. But a better understanding of the psychology of waiting can help make it a bit more bearable. When all else fails, bring a book or a smart phone will also do.

1.In the 1st paragraph, the author intends to tell us_____.

A. why people are crazy about Apple’s products

B. people waste their precious time in queuing

C. waiting time is not the only cause for people’s hate in queuing

D. the psychology is the real reason why people hate to wait in lines

2.Walt Disney Co makes people queuing happily by_____.

A. having people queue in serpentine line

B. letting people know how long they will wait exactly

C. making people queue shorter than they are informed

D. offering people magazines to read when waiting in lines

3.Serpentine line was invented to_____.

A. make the waiting line move faster

B. guarantee the first-come-first-served principle

C. solve the problem of feeling bored in queuing

D. guide all customers into one big snaking queue

4.The main purpose of the passage is _____.

A. to explain the advantages of serpentine line

B. to introduce ways of saving time in queuing

C. to offer an explanation of the psychology of queuing

D. to analyze the psychology of people queuing for Apple products

科目:高中英語 來源:2013-2014學年安徽省六校教育研究會高三2月聯考英語試卷(解析版) 題型:閱讀理解

I once had a house guest from Cuba. During his visit, I happened to throw an old broken blender (攪拌機) in the trash. The next day it was sitting on my counter – in working order. In his world, people simply cannot afford to replace an item which doesn't work properly. They take the time and figure out how to fix it. In Cuba, they are still driving cars from the 1960’s, mainly because they do not have a choice. 

In contrast, the U.S. is a “throw-away society.” Statistics show that each American produces six pounds of trash per day. I believe a combination of factors has contributed to this phenomenon.

“Planned obsolescence(廢棄)” is not a secret. It is a manufacturing (制造業) philosophy developed in the 1920’s and 1930’s, when mass production became popular. The goal is to make a product or part that will fail, or become less desirable over time or after a certain amount of use. This pressures the consumer to buy again. 

Planned obsolescence does keep costs down. Instead of making an expensive product that will last a long time, businesses produce more affordable, disposable(一次性的) items. Some electronic items have become so inexpensive that it is cheaper to replace them than to repair them.

Busy people often value their time and convenience more than money. If a car starts to have mechanical problems, replacing it with a newer, more reliable model may be more appealing than tolerating it being in the garage for a week.

In addition, advertising trains consumers to want what is new and improved. It convinces them that the more they have, the happier they will be. 

Unlike people in many developing countries, we live in a world of abundance. A study by Dr. Timothy Jones of the University of Arizona also found that in the U.S., 40-50 percent of all food ready for harvest is wasted. Abundance and waste soon became closely associated in the American way of life.

1.In Cuba, people usually fix a broken item instead of buying a new one because __________.

A. wasting is prohibited there                                         B. they are poor

C. they are interested in fixing things                            D. they live a low-carbon life

2.According to the article, planned obsolescence ___________.

A. began before mass production became popular

B. is intended to encourage consumers to buy more things

C. results in higher prices of items

D. requires factories to produce high-quality products

3.Which of the following is NOT true about the “throw-away society” in the U.S.?

A. People prefer to buy a new blender rather than repair the broken one.

B. A large quantity of food has been wasted.

C. People believe that the more they have, the happier they will be.

D. People all hold the belief that money comes first.

4.What may be the writer’s attitude towards a throw-away society?

A. Supportive.                     B. Critical.                    C. Tolerant.                           D. Optimistic.

For generations here in the deepest South, there had been a great taboo(禁忌): publicly crossing the color line for love. Less than 45 years ago, marriage between blacks and whites was illegal, and it has been forbidden for much of the time since.

So when a great job about an hour’s drive north of the Gulf Coast attracted him, Jeffrey Norwood, a black college basketball coach, had reservations. He was in a serious relationship with a woman who was white and Asian.

“You’re thinking about a life in South Mississippi?” his father said in a skeptical voice, recalling days when a black man could face mortal(致命的) danger just being seen with a woman of another race, regardless of intentions. "Are you sure?"

But on visits to Hattiesburg, the younger Mr. Norwood said he liked what he saw: growing diversity. So he moved, married, and, with his wife, had a baby girl, who was counted on the last census(人口普查) as black, white and Asian. Taylor Rae Norwood, three, is one of thousands of mixed-race children who have made this state home to one of the nation's most rapidly expanding multiracial populations, up 70 percent between 2000 and 2010, according to new data from the Census Bureau.

In the first comprehensive accounting of multiracial Americans since statistics were first collected about them in 2000, reporting from the 2010 census, made public in recent days, shows that the nation’s mixed-race population is growing far more quickly than many researchers had estimated, particularly in the South and parts of the Midwest. That conclusion is based on the bureau’s analysis of 42 states; the data from the remaining eight states will be released soon.

In North Carolina, the mixed-race population doubled. In Georgia, it grew by more than 80 percent, and by nearly as much in Kentucky and Tennessee. In Indiana, Iowa and South Dakota, the multiracial population increased by about 70percent.

Census officials estimated the national multiracial growth rate was about 35 percent since2000 according to the known result, when seven million people ----- 2.4 percent of the population ------ chose more than one race.

1.If a black man married a white woman 50 years ago, the worst result was that _____.

A.he was sentenced to death                B.he was considered to be immoral

C.he was criticized by the public              D.he was treated as a lawbreaker

2.The underlined word “serious” in Paragraph 2 can be replaced by “____”.

A.stable            B.bad              C.mixed            D.dangerous

3.What can we infer from Paragraph 4?

A.Jeffrey Norwood was born in Hattiesburg and grew up there.

B.Taylor Rae Norwood’s mother is a white-Asian.

C.70 percent of the people in Mississippi are multiracial.

D.Mississippi has the largest multiracial population in the US.

4.Which of the following states had the fastest growth rate of mixed-race population?

A.Georgia.          B.Tennessee.        C.North Carolina.     D.South Dakota.
