7.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 have 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 Classic 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 (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 19regular cola drinkers and 27diet 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 7out of 19regular cola drinkers correctly identified their brand of choice in all four trials.The diet-cola drinkers did a little worse-only 7of 27identified all four samples correctly.
While both groups did better than chance would predict,nearly half the participants in each group made the wrong choice two or more times.Two people got all four samples wrong.Overall,half of 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.

28.It is implied in the first paragraph thatC.
A.the purpose of taste tests is to promote the sale of colas
B.the improvement of quality is the chief concern of the two cola companies
C.the competition between the two colas is very strong
D.blind tasting is necessary for identifying fans
29.According to the passage the preference test was conducted in order toA.
A.find out the role taste preference plays in a person's drinking
B.reveal which cola is more to the liking of the drinkers
C.show that a person's opinion about taste is mere guess-work
D.compare the ability of the participants in choosing their drinks
30.The word'burnout"underlined in Paragraph Five,refers to the state ofD.
A.being seriously burnt in the skin
B.being unable to burn for lack of fuel
C.being badly damaged by fire
D.being unable to function because of excessive use
31.The author's purpose in writing this passage is toA.
A.show that taste preference is highly subjective
B.a(chǎn)rgue that taste testing is an important marketing strategy
C.emphasize that taste and price are closely related to each other
D.recommend that blind tasting be introduced in the quality control of colas.

分析 文章提出味覺(jué)偏好是十分主觀的,并且通過(guò)一些實(shí)驗(yàn)來(lái)證明個(gè)人對(duì)味覺(jué)的感受帶有主觀性.

解答 28-31 CADA
28.C 推理題.由第1段第3句中Coca Cola and Pepsi Cola are marketed so aggressively可知兩大公司競(jìng)爭(zhēng)極為激烈,故選C.
29.A 推理題.第1段第3句提到we have wondered how big a role taste preference actually plays in brand loyalty,由于兩大可樂(lè)公司的營(yíng)銷(xiāo)如此具有攻擊性,我們不由想知道對(duì)味道的偏好在品牌忠誠(chéng)度上起多大的作用,A與之相符.
30.D 猜測(cè)詞意題.文章最后一段第3句中,fatigue與taste bum out之間用or連接,表明兩者語(yǔ)義比較接近,對(duì)比四個(gè)選項(xiàng),D符合,表示味覺(jué)疲勞、麻木.
31.A 主旨大意題.文章第1句Taste is such a subjective matter that we don't usually conduct preference tests for 表明味覺(jué)偏好是十分主觀的,且下文講到的實(shí)驗(yàn)結(jié)果也更進(jìn)一步印證了該觀點(diǎn),故選A.

11.When it comes to human resources,hiring highly-skilled staff is not usually enough for a company to function successfully.Besides the knowledge in their particular fields,employees must always have additional skills-----those of co-operation.In the case that work tasks can only be carried out by communicating with people,accepting common decisions,solving problems,sharing information and helping one another,teamwork skills are important.
While some jobs may require talent,the ability to work as a team is learned.There are no complicated formulas(規(guī)則); you don't need to have any special qualities or exceptional mental abilities.Individuals can be effective as a team if they have developed certain behaviors or habits of communication.Many companies,clubs and organizations use team building activities.Team building activities may include a number of teamwork elements.They are aimed at encouraging active participation in task accomplishment while all members have their roles as individuals and are able to co-operate towards a common goal as a team.

9.Andy rode slowly on his way to school,day-dreaming about the fishing trip that his father had promised him.He was so busy dreaming about all the fish he would catch that he was unaware of everything else around him.
He rode along until a strange sound drew him to the present.He came to a stop and looked curiously up to the heavens.What he saw shocked and terrified him.A huge swarm of bees filled the sky like a black cloud and the buzzing mass seemed to be heading angrily towards him.
With no time to waste,Andy sped off in the opposite direction,riding furiously-but without knowing how to escape the swarm.With a rapidly beating heart and his legs pumping furiously,he sped down the rough road.As the bees came closer,his panic increased.Andy knew that he was sensitive to bee stings(蜇).The last sting had landed him in hospital-and that was only one bee sting!He had been forced to stay in bed for two whole days.Suddenly,his father's words came to him."When you are in a tight situation,don't panic.Use your brain and think your way out of it."
On a nearby hill,he could see smoke waving slowly skywards from the chimney of the Nelson family home."Bees don't like smoke,"he thought."They couldn't get into the house."Andy raced towards the Nelson house,but the bees were gaining ground.Andy knew he could not reach the house in time.He estimated that the bees would catch up with him soon.
Suddenly,out of the corner of his eyes,he spotted a small dam used by Mr.Nelson to irrigate his vegetable garden.Off his bike and into the cool water he lived,disappearing below the surface and away from the savage insects.After holding his breath for as long as he could,Andy came up for air and noticed the bees had gone.Dragging himself out of the dam,he struggled up the hilly slope and rang the doorbell.Mrs.Nelson took him inside and rang his mother.
"You'll really need that fishing break to help you recover,"laughed his mother with relief."Thank goodness you didn't panic!"But Andy did not hear her.He was dreaming once again of the fish he would catch tomorrow.

4.Why did Andy fail to notice the swarm of bees earlier?D
A.He was riding to school.
B.He was listening to a strange sound.

A.They crowded like a black cloud.
B.They shocked and terrified Andy.
C.They tried to attack Andy in a mass.
D.They made Andy stay in hospital for two days.

A.He rode off in the opposite direction.
B.He asked Mr.Nelson for help.
C.He hid himself under the water.
