Close relationships, thought to help communication by giving speakers a common context, are actually more likely to make crossed wires than when strangers are involved, a new study suggests.

Because close colleagues and friends already share so much common knowledge that they often use short, ambiguous(模糊的) messages which can lead to misunderstandings.

“People are so used to talking with those with whom they already share a great deal of information that, when they have something really new to share, they often present it in a way that they assume the person already knows it.” says study-team member Boaz Keysar.

Keysar and his graduate student, Shall Wu, trained 40 pairs of undergraduate students to memorize made-up names and descriptions of strange shapes. In each pair, the “director” had to communicate the identity of one of the 24 shapes. The partner had to use the information to choose the correct shape from a set of three images on a computer monitor.

Half of the partners studied only the first six shapes, while the others learned the first 18 shapes. The directors, who had memorized all the shapes, were aware of their partners’ knowledge levels of the shapes.

In the pairs with the most shared knowledge, the directors were more likely to rattle off (快速背出)shape names, compared with pairs with little knowledge overlap(重合), in which the directors were more likely to describe the actual shapes. Not surprisingly, participants with more shared knowledge were twice as likely to ask for clarification as those with less overlap.

Language itself can be confusing. “The reason all this is happening at all is that language in general is ambiguous,” said Keysar.

He recalls an ambiguous billboard near a stadium holding a Rolling Stones concert that night. The billboard read, “Avoid LSD tonight.” (注：LSD常作”迷幻药”的缩略语)

Hmmm? “It was about Lake Shore Drive, and I’m sure the writer of the sign didn’t realize he was being ambiguous,” Keysar said.

“Even though miscommunication can lead to missed meetings or deadlines, people are often unaware when their language is ambiguous,” Keysar added, “We don’t realize we say things that are ambiguous,” he said, “and that’s a problem.”

64. What does the underlined part in Paragraph 1 mean?

A. Electric wires joined together.                 B. Riddles hard to figure out.

C. Misunderstandings in communication.     D. Offensive remarks.

65. In Keysar’s experiment, which of the following gives more accurate descriptions of the shapes?

A. The “directors” of the pairs with little shared knowledge.

B. The “directors” of the pairs who shared more knowledge.

C. The partners whose directors rattle off shape names.

D. The partners whose directors give clear clarifications.

66. It can be inferred from the example of the billboard that _________.

A. most people know what LSD usually refers to

B. local people would not misunderstand the meaning of LSD

C. the writer of the sign means to play jokes on those attending the concert

D. people sometimes ignore the limitation of shared knowledge

67. By this passage, the author mainly wants to say ___________.

A. ambiguous language can lead to misunderstandings

B. familiarity can mess up communication

C. accurate descriptions of identity help guess shapes

D. close relationships do not mean good communication

This is a dangerous world we live in. The numbers of murders goes up every year； people are dying of cancer；more people contract（感染）HIV；more teens are using drugs；etc. You know this because you’ve heard all the statistics on the news. But do you really have an accurate idea what they mean? The numbers are going up, but how do they compare to the growth in population? Are more cases of these diseases being reported because of better testing techniques, or are the diseases more common? The fact is that without knowing the background, statistics mean very little.
This growing trend of reporting only part of the information is becoming dangerous.
For example, several years ago a high school student reported dangers of the chemical known as dihydrogen monoxide. This chemical, found in most cancerous tumors（肿瘤）， is found in the blood of people drunk on alcohol, and causes complete physical and mental dependence for those who take the chemical even once. After reading his report, more than 75% of his Advanced Placement Chemistry class voted to forbid this dangerous chemical! Every one of the above statements is true, yet this chemical is necessary to all life on earth. The students made the mistake because they voted knowing only a few statements and statistics, rather than the chemical’s full background.
The point of this article is that one should be aware of what is and is not being said. When one finds a new fact or number, one should try to consider other important information before forming an opinion with only half-truths. Always remember that the author is trying to convince you of his or her own view, and will leave out information that is different to his view. For example, look again at the statistics that suggest skiing is safe. Only 32 people may die each year when skiing, while 897 die from lightning strikes, but which is really more dangerous? If you think about it, you will realize far fewer people go skiing each year than the number of people who are in danger of a lightening strike. When you think about it, skiing is more dangerous than you might at first think when looking at statistics. If we teenagers are to be left in this world, we had better be able think critically, and form our own views. rather than be easily persuaded by another’s. To be warned is to be prepared.
59．In the first paragraph, what problem does the writer want to warn us?
A. We are now living in a dangerous world.
B. We got a lot of false statistics from the media.
C. There are around us more and more murders, diseases etc.
D. Statistics alone without full background don’t give us an accurate picture of things.
60．Why does the writer use the example in the second paragraph?
A. To show the danger of reporting only part of the information.
B. To argue that high school students are easily persuaded.
C. To prove what is necessary to us might be dangerous.
D. To warn us of the harmful substances（物质）around us.
61．Relative information is often left out because__________
A. relative information is not that important
B. the author is trying to show what he or she says is true
C. too much information will make readers feel confused
D. readers are not able to analyze so much information at once
62．What is the main idea of this passage?
A. Some measures must be taken to protect our dangerous world.
B. We should learn to think critically and look at problems from all sides.
C. The growing trend of reporting only half-truths is getting out of control.
D. Teenagers ought to improve their ability of telling right from wrong.
