Meetings are very common nowadays. They can be weekly, monthly or annually. Some people think most meetings feel like a waste of time. They seem pointless and boring at times.
Then how do you run an effective meeting？
First, assign roles, such as greeter, timekeeper and note taker, so that you, the organizer, can be free to lead discussions and presentations.
Next, take charge from the start. Everyone will listen to you and join your discussion if you take charge in every aspect of the meeting. Show everyone that you really know what you are talking about, and everything that you talk about is useful.
Most important of all, follow the agenda. At the end of the meeting, spend a little extra time for the participants to discuss anything that needs to be immediately discussed but which may not have been on the agenda.
Always ask the participants questions to speak their minds and keep them interested. Remember that a good meeting is a two-way communication. Be open to everyone's opinion, ideas, and suggestions. Don't forget to thank them for the ideas they present.
And finally, close the meeting with everyone knowing what is expected of them and what they should do for the following weeks.Then, send out meeting minutes within a few days, while everyone still remembers the points.
1. A successful meeting should have different people to play different roles. {T、F}
2. Generally people only discuss the items listed on the agenda in a successful meeting.{T、F}
3. An unsuccessful meeting might be full of single-way communication. {T、F}
4. When the meeting is closed, it means there is nothing to do in the following weeks. {T、F}
5. Minutes should be sent out to the participants within a month after the end of the meeting. {T、F}
Questions are based on the following passage.
Cocoa contains chemicals calledflavanols （黄烷醇 ） that may help reduce the risk of strokes and heart attacks by lowering blood pressure and improving the body"s use of insulin （胰岛素 ） .
Washington chocolate producer Steve Kumar said that is one reason dark chocolate is increasingly popular among his customers. "A lot of people are attracted by dark chocolate because they just decide they love it， and they also have been reading all about the health benefits of dark chocolate，" said Kumar.
But those benefits have not been confirmed by studies involving large numbers of people. Also， during the production of chocolate， a lot of flavanols are destroyed， while sugar and fats are added to contribute to flavor.
Scientists now want to learn the benefits of flavanols in their pure form.
They plan a four-year study of 18，000 adults， who will take pills of pure cocoa flavanols， in what is being called the largest test of its kind. Jo-Ann Manson， of the Brigham and Women"s Hospital in Boston， is the lead researcher. "This pill of cocoa flavanols will avoid having the calories and the sugar and the fat found in chocolate，" said Manson. The pills also won"t have any taste. Participants，divided in two groups， will take two identical pills a day. One group"s pills will contain flavanols， while the others will getplacebo （安慰剂 ） pills. "The amount of chocolate that it would take in order to have this amount of cocoa flavanols would be more than ten times the amount that people would ordinarily eat，" said Manson.
Whatever the outcome of the study， Kumar said he"s not worried about his business. "People like the experience of actually biting into a piece of chocolate，whatever their favorites are，" he said.
The flavanol benefits test is still in the early stage， so scientists are not sure when the participants will be handed their first chocolate pills.
What chemical in cocoa may do good to the heart according to the passage？ 查看材料
A.Fat.
B.Insulin.
C.Sugar.
D.Flavanols.
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 tellingtheir 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 to 27 identified 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 the participants did about as well on the last round of tasting as on the first, so fatigue, 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.
71.According to the passage the preference test was conducted in order to _______.
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
72.The statistics recorded in the preference tests show _____.
A.Coca-Cola and Pepsi are people's two most favorite drinks
B.there is not much difference in taste between Coca-Cola and Pepsi
C.few people had trouble telling Coca-Cola from Pepsi
D.people's tastes differ from one another
73.It is implied in the first paragraph that ______.
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
74.The word "burnout" (Line 4, Para. 5) here refers to the state of _____.
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
75.The author's purpose in writing this passage is to ______.
A.show that taste preference is highly subjective
B.argue 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
Obama's success isn't all good news for black Americans
As Erin White watched the election results head towards victory for Barack Obama, she felt a burden lifting from her shoulders. "In that one second, it was a validation for my whole race," she recalls.
"I've always been an achiever," says White, who is studying for an MBA at Vanderbilt University in Nashville, Tennessee. "But there had always been these things in the back of my mind questioning whether I really can be who I want. It was like a shadow, following me around saying you can only go so far. Now it's like a barrier has been let down."
White's experience is what many psychologists had expected - that Obama would prove to be a powerful role model for African Americans. Some hoped his rise to prominence would have a big impact on white Americans, too, challenging those who still harbour racist sentiments. "The traits that characterise him are very contradictory to the racial stereotypes that black people are aggressive and uneducated," says Ashby Plant of Florida State University. "He's very intelligent and eloquent."
Sting in the tail
Ashby Plant is one of a number of psychologists who seized on Obama's candidacy to test hypotheses about the power of role models. Their work is already starting to reveal how the "Obama effect" is changing people's views and behaviour. Perhaps surprisingly, it is not all good news: there is a sting in the tail of the Obama effect.
But first the good news. Barack Obama really is a positive role model for African Americans, and he was making an impact even before he got to the White House. Indeed, the Obama effect can be surprisingly immediate and powerful, as Ray Friedman of Vanderbilt University and his colleagues discovered.
They tested four separate groups at four key stages of Obama's presidential campaign. Each group consisted of around 120 adults of similar age and education, and the test assessed their language skills. At two of these stages, when Obama's success was less than certain, the tests showed a clear difference between the scores of the white and black participants—an average of 12.1 out of 20, compared to 8.8, for example. When the Obama fever was at its height, however, the black participants performed much better. Those who had watched Obama's acceptance speech as the Democrats' presidential candidate performed just as well, on average, as the white subjects.After his election victory, this was true of all the black participants.
Dramatic shift
What can explain this dramatic shift？ At the start of the test, the participants had to declare their race and were told their results would be used to assess their strengths and weaknesses. This should have primed the subjects with "stereotype threat" – an anxiety that their results will confirm negative stereotypes, which has been shown to damage the performance of African Americans.
Obama's successes seemed to act as a shield against this. "We suspect they felt inspired and energised by his victory, so the stereotype threat wouldn't prove a distraction," says Friedman.
Lingering racism
If the Obama effect is positive for African Americans, how is it affecting their white compatriots (同胞)？ Is the experience of having a charismatic (有魅力的) black president modifying lingering racist attitudes？ There is no easy way to measure racism directly; instead psychologists assess what is known as "implicit bias", using a computer-based test that measures how quickly people associate positive and negative words—such as "love" or "evil"—with photos of black or white faces. A similar test can also measure how quickly subjects associate stereotypical traits—such as athletic skills or mental ability—with a particular group.
In a study that will appear in the Journal of Experimental Social Psychology, Plant's team tested 229 students during the height of the Obama fever. They found that implicit bias has fallen by as
A．Excited.
B．Victorious.
C．Anxious.
D．Relieved.
We rose tint our memories and put ourselves into self-affirming situations. We become defensive when criticized, and apply negative stereotypes to others to boost our own esteem, we stalk around thinking we’re hot stuff.
Psychologist and behavioral scientist Nicholas Epley oversaw a key studying into self-enhancement and attractiveness. Rather that have people simply rate their beauty compress with others, he asked them to identify an original photogragh of themselves’ from a lineup including versions that had been altered to appear more and less attractive. Visual recognition, reads the study, is “an automatic psychological process occurring rapidly and intuitively with little or no apparent conscious deliberation”. If the subjects quickly chose a falsely flattering image- which must did- they genuinely believed it was really how they looked. Epley found no significant gender difference in responses. Nor was there any evidence that, those who self-enhance the must (that is, the participants who thought the most positively doctored picture were real) were doing so to make up for profound insecurities. In fact those who thought that the images higher up the attractiveness scale were real directly corresponded with those who showed other makers for having higher self-esteem. “I don’t think the findings that we having have are any evidence of personal delusion”, says Epley. “It’s a reflection simply of people generally thinking well of themselves’. If you are depressed, you won’t be self-enhancing. Knowing the results of Epley ‘s study,it makes sense that why people heat photographs of themselves Viscerally-on one level, they don’t even recognise the person in the picture as themselves, Facebook therefore ,is a self-enhancer’s paradise,where people can share only the most flattering photos, the cream of their wit ,style. ,beauty, intellect and lifestyle. it’s not that people’s profiles are dishonest,says catalina toma of Wiscon—Madison university ,”but they portray an idealized version of themselves.
According to the first paragraph, social psychologist have found that ______ .
A.our self-ratings are unrealistically high
B.illusory superiority is baseless effect
C.our need for leadership is unnatural
D.self-enhancing strategies are ineffective
Visual recognition is believed to be people’s______ .A.rapid watching
B.conscious choice
C.intuitive response
D.automatic self-defence
Epley found that people with higher self-esteem tended to______ .A.underestimate their insecurities
B.believe in their attractiveness
C.cover up their depressions
D.oversimplify their illusions
The word “Viscerally”(Line 2,para.5) is closest in meaning to_____.A.instinctively
B.occasionally
C.particularly
D.aggressively
It can be inferred that Facebook is self-enhancer’s paradise because people can _____.A.present their dishonest profiles

Survey results indicate that smoking and alcohol and marijuana(大麻) use increased among residents of Manhattan during the 5～8 weeks after the terrorist attacks on the World Trade Center which took place on September 11, 2001. Almost one third of the nearly 1,000 persons interviewed reported an increased use of alcohol, marijuana, or cigarettes following the September 11th attacks. The largest increase was in alcohol use. 1About one fourth of the respondents said they were drinking more alcohol in the weeks after September 11; about 10% reported an increase in smoking, and 3.2% said they had increased their use of marijuana.
The investigators found survey participants by randomly dialing New York City phone numbers and screened (筛选) potential respondents for Manhattan residents living in areas close to the World Trade Center. Interviews were conducted with 988 individuals between October 16 and November 15, 2001. Participants were asked about their cigarette smoking, alcohol drinking, and marijuana use habits before and after September 11. During the week prior to September 11, 2001, 22.6% of the participants reported smoking cigarettes, 59.1% drinking alcohol, and 4.4% using marijuana. After September 11th, 23.4% reported smoking cigarettes, 64.4% drinking alcohol, and 5.7% smoking marijuana. Among those who smoked, almost 10% reported smoking at least an extra pack of cigarettes a week and among those who drank alcohol, more than 20% reported drinking at least one extra drink a day.
The researchers found that people who reported an increase in substance abuse were more likely to suffer from post traumatic(外伤的)stress disorder (PTSD) and from depression. People who reported an increase in cigarette smoking or marijuana use were also more likely to have both P1SD and depression, while those who reported an increase in alcohol use were more likely to have depression only. Persons who were living closer to the World Trade Center were more likely to increase their cigarette smoking, but other factors such as being displaced from home, losing possessions during the attacks, or being involved in the rescue efforts were not consistently associated with increased substance use. Symptoms of panic attack were associated with an increase in the use of all substances.
Increase in substance abuse did not differ significantly between men and women or among racial or ethnic groups. Demographic(人口统计学的) factors such ms age, marital status, and income seemed to play a more critical role in determining if the events of September 11th led to an increase in substance use.
The survey results suggest that the largest increase in substance use was ______.
A．alcohol
B．marijuana
C．cigarettes
D．cocaine
High Stress May Damage Memory
According to a report issued in May 1998，elderly people who have consistently high b1ood levels of cortisol don’t score as well on memory tests as their peels with lower levels of the stress hormone．What’s more． high 1evels of cortisol are also associated with shrinking 0f the hippocampus，a region of the brain that plays a key role in learning and memory．The 6ndings suggest that even cortisol levels in the normal，“healthy” range can actually accelerate brain aging．
The study results “now provide substantial evidence that long—term exposure to adrenal stress hormones may promote hippocampal aging in normal elderly humans，”write Nada Porter and Philip Landfield of the University of Kentucky in Lexington in their editorial．Cortisol is a hormone released in response to stress by the adrenal glands，which sit on top of the kidneys．
Over a 5 to 6一year period，Dr． Sonia Lupien and his colleagues measured 24一hour cortisol levels in 51 healthy volunteers，most of Whom were in their 70s．
Despite wide variation in cortisol levels．the participants could be divided into three Subgroups：those whose cortisol progressively increased over time and was currently high（increasing／high）：those whose cortisol progressively increased over time and was currently moderate（increasing／moderate）；and subjects whose cortisol decreased，but Was currently moderate（decreasing／moderate）．
The researchers tested the volunteers’ memory on six people in the increasing／high category and five people in the decreasing／moderate group．The groups did not differ on tests of immediate memory，but the increasing／high cortisol group had other memory problems compared with those in the decreasing／moderate group．
The researchers also found that the total volume of the hippocampus in those in the increasing／high group was 14％ lower than those in the decreasing／moderate group，although there were no differences in 0ther brain regions．
The results suggest that brain aging Can be accelerated by levels of adrenal hormones that are not generally regarded as pathological and that variation within this normal range is related to variation in the rate of brain aging．”write Porter and Landfield．“This further suggests that chronic stress may accelerate the worsening of hippocampus．”
第 26 题 The part of the brain important for a person’s learning and memory is．
A．the cortisol．
B．the adrenal glands．
C．the stress hormones
D．the hippocampus．
