Rome had the Forum. London has Speaker’s Corner. Now always-on-the-go New Yorkers have Liz and Bill.
Liz and Bill, two college graduates in their early 20s, have spent a whole year trying to have thousands of people talk to them in subway stations and on busy street corners. Just talk. 
Using a 2-foot-tall sign that says, "Talk to Me," they attract conversationalists, who one evening included a mental patient, and men in business suits.
They don't collect money. They don't push religion (宗教). So what's the point?
“To see what happens ,”said Liz. “We simply enjoy life with open communication(交流).”
Shortly after the September 11, 2001 attacks, they decided to walk from New York City to Washington, a 270-mile trip. They found they loved talking to people along the way and wanted to continue talking with strangers after their return.
“It started as a crazy idea,” Liz said. “We were so curious about all the strangers walking by with their life stories. People will talk to us about anything: their jobs, their clothes, their childhood experiences, anything.”
Denise wanted to talk about an exam she was about to take. She had stopped by for the second time in two days, to let the two listeners know how it went.
Marcia had lost her husband to a serious disease. “That was very heavy on my mind,” Marcia said. “To be able to talk about it to total strangers was very good,” she explained.
To celebrate a year of talking, the two held a get-together in a city park for all the people they had met over the past year. A few hundred people showed up, as well as some television cameramen and reporters.
They may plan more parties or try to attract more people to join their informal talks. Some publishers have expressed interest in a book, something they say they'll consider.
【小題1】What did Liz and Bill start doing after September 2001?

A．Chatting with people.B．Setting up street signs.
C．Telling stories to strangers.D．Organizing a speaker's corner.
【小題2】What they have been doing can be described as______.
A．pointless B．normalC．crazyD．successful
【小題3】Why are Denise and Marcia mentioned in the text?
A．They knew Liz and Bill very well.
B．They happened to meet the writer of the text.
C．They organized the get-together in the city park.
D．They are examples of those who talked to Liz and Bill.
【小題4】What will Liz and Bill do in the future?
A．Go in for publishing.B．Do more television programs.
C．Continue what they are doing.D．Spend more time reading books.
【小題5】 How do they like the idea of writing a book?

Directions: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.
Sociologists have long recognised that organisations of less than 200 individuals can operate through the free flow of information among the members. Once their size goes beyond this figure, the organizations are getting less flexible. So it seems necessary to prevent total disorder resulting from failures of communication.
One solution to this problem would, of course, be to structure large organisations into smaller units of a size that can act as a group. By allowing these groups to build reliance on each other, larger organizations can be built up. However, merely having groups of, say, 150 will never of itself be a complete solution to the problems of the organization. Something else is needed: the people involved must be able to build direct personal relationships. To allow free flow of information, they have to be able to communicate with each other in a casual way. Maintaining too formal a structure of relationships inevitably prevents the way a system works.
The importance of this was drawn to my attention two years ago by the case of a TV station. Whether by chance or by design, it so happened that there were almost exactly 150 people in the station. The whole process worked very smoothly as an organization for many years until they were moved into purpose-built accommodation. Then, for no apparent reason, the work seemed to be more difficult to do, not to say less satisfying.
It was some time before they work out what the problem was. It turn out that, when the architects were designing the new building, they decided that the coffee room where everyone ate their sandwiches at lunch times was an unnecessary luxury and so did away with it. And with that, they accidentally destroyed the close social networks that strengthened the whole organization. What had apparently been happening was that, as people gathered informally over their sandwiches in the coffee room, useful information was casually being exchanged.
(Note: Answer the questions or complete the statements in NO MORE THAN EIGHT WORDS.)
【小題1】What size of an organization may lead to communication failures?
【小題2】What are the two solutions to the communication problem within a large organization?
【小題3】After the TV station moved into new accommodation, its operation ___________________________.
【小題4】From the case of the TV station, we can conclude it is ____________________________________ that make(s) an organization more successful.

People who multitask all the time may be the worst at doing two things at once, a new research suggests. The findings, based on performances and self-evaluation by about 275 college students, indicate that many people multitask not out of a desire to increase productivity, but because they are easily distracted and can’t focus on one activity. And “those people turn out to be the worst at handling different things,” said David Sanbonmatsu, a psychologist at the University of Utah.

Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked, how good they thought they were at it, and how sensation-seeking (尋求刺激) or imperative (沖動(dòng)) they were. They then evaluated the participants’ multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters.

Not surprisingly, the scientists said, most people thought they were better than average at multitasking, and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once. But those who frequently deal with many things at the same time were found to perform the worst at the actual multitasking test. They also were more likely to admit to sensation-seeking and impulsive behavior, which connects with how easily people get bored and distracted.

“People multitask not because it’s going to lead to greater productivity, but because they’re distractible, and they get sucked into things that are not as important.” Sanbonmatsu said.

Adam Gazzaley, a researcher at the University of California, San Francisco, who was not a member of the research group, said one limitation of the study was that it couldn’t find out whether people who start out less focused tend toward multitasking or whether people’s recognizing and understanding abilities change as a result of multitasking.

The findings do suggest, however, why the sensation-seeker who multitask the most may enjoy risky distracted driving. “People who are multitasking are generally less sensitive to risky situations.” said Paul Atchley, another researcher not in the group. “This may partly explain why people go in for these situations even though they’re dangerous.”

1.The research led by Sanbonmatsu indicates that people who multitask __________.

A. seek high productivity constantly

B. prefer handling different things when getting bored

C. are more focused when doing many things at a time

D. have the poorest results in doing various things at the same time

2.When Sanbonmatsu and his colleagues conducted their research, they __________.

A. assessed the multitasking ability of the students

B. evaluated the academic achievements of the students

C. analyzed the effects of the participants’ tricky mental tasks

D. measured the changes of the students’ understanding ability

3.According to Sanbonmatsu, people multitask because of their __________.

A. limited power in calculation

B. interests in doing things differently

C. inability to concentrate on one task

D. impulsive desire to try new things

4.From the last paragraph, we can learn that multitaskers usually __________.

A. drive very skillfully

B. go in for different tasks

C. fail to react quickly to potential dangers

D. refuse to explain the reasons for their behavior

科目：高中英語(yǔ) 來(lái)源：2012-2013學(xué)年浙江省桐鄉(xiāng)市高三模擬考試英語(yǔ)試卷（解析版） 題型：閱讀理解

55% of deaths caused by road accidents occur in the first few minutes after a crash. Up to 85% of these deaths could be prevented if first aid were given. The first person on the scene of a road accident will almost certainly be another road user. So as a driver your knowledge of first aid could make a real difference to someone in the event of a road accident.

Assess conditions

·Remain calm. Judge the scene and seriousness of the collision.

·Determine what has happened, how many people and vehicles are involved and the exact location.

·Determine how many casualties(傷亡人數(shù)) there are, what is the severity of the injuries, whether anyone is trapped, and whether there is a danger of fire.

Make safe

·Make sure you stay safe and keep off the road. If you need to stop or warn approaching cars, signal to them from the pavement. Wear reflective clothing, use warning triangles, flashing lights and warning lights. Don’t smoke.

·If you are in a car and you come across an accident, first park safely and turn off the engine before you get out to help. Use a triangle warning danger if necessary.

·Consider the safety of others. Don’t move the vehicles, look out for dangers — leaking fuel, chemicals, broken glass or dropping loads — guide uninjured passengers to a place of safety.

Call for help

Dial 999 (or 112) for the emergency services. If there is no phone nearby, send two people in opposite directions to seek help.

Do this as soon as you can or get someone else to do it while you deal with an injured person. You will need to tell the emergency services:

·where you are

·what has happened (describe the accident)

·how many people are injured

·whether they are breathing or bleeding.

The operator will talk you through what to do while you wait for an ambulance to arrive.

Apply emergency first aid

·Remain calm. Reassure the victims.

·Do not allow smoking or offer food or drink to casualties as this could hamper urgent medical treatment.

1.The passage mainly tells us ______.

A. how to reduce road accident deaths

B. how to perform first aid in a road accident

C. how to treat the injured people on the scene

D. how to protect us from being injured in an accident

2.When a driver is applying first aid, which of the following is proper?

A. Stand in the middle of the road to stop or warn approaching cars.

B. Leave the engine working when he gets out of his car to help.

C. Call 999 for an ambulance to come and leave the scene immediately.

D. Make sure the scene is safe enough and stay away from dangerous gas leaking.

3.What does the underlined word “hamper” mean in the last paragraph?

A. Affect.                     B. Improve.                 C. Demand.                    D. Judge.

4.The passage is most likely to appear in a newspaper’s ______ section.

A. business and finance                            B. sports and entertainment

C. travel and traffic                                       D. customs and cultures
