Most of us are taught to pay attention to what is said—the words. Words do provide us with some information, but meanings are derived from so many other sources that it would hinder our effectiveness as a partner to a relationship to rely too heavily on words alone. Words are used to describe only a small part of the many ideas we associate with any given message. Sometimes we can gain insight into some of those associations if we listen for more than words. We don’t always say what we mean or mean what we say. Sometimes our words don’t mean anything except “ I’m letting off some steam. I don’t really want you to pay close attention to what I’m saying. Just pay attention to what I’m feeling.” Mostly we mean several things at once. A person wanting to purchase a house says to the current owner, “This step has to be fixed before I’ll buy.” The owner says, “ It’s been like that for years.” Actually, the step hasn’t been like that for years, but the unspoken message is: “ I don’t want to fix it. We put up with it. Why can’t you?” The search for a more expansive view of meaning can be developed of examining a message in terms of who said it, when it occurred, the related conditions or situation, and how it was said.

When a message occurs can also reveal associated meaning. Let us assume two couples do exactly the same amount of kissing and arguing. But one couple always kisses after an argument and the other couple always argues after a kiss. The ordering of the behaviors may mean a great deal more than the frequency of the behavior. A friend’s unusually docile behavior may only be understood by noting that it was preceded by situations that required an abnormal amount of assertiveness. Some responses may be directly linked to a developing pattern of responses and defy logic. For example, a person who says “No!” to a serials of charges like “You’re dumb,” “You’re lazy,” and “You’re dishonest,” may also say “No!” and try to justify his or her response if the next statement is “And you’re good looking.”

We would do well to listen for how messages are presented. The words, “If sure has been nice to have you over,” can be said with emphasis and excitement or ritualistically. The phrase can be said once or repeated several times. And the meanings we associate with the phrase will change accordingly. Sometimes if we say something infrequently it assumes more importance; sometimes the more we say something the less importance it assumes.

1.Effective communication is rendered possible between two conversing partners, if ___.

A.they use proper words to carry their ideas.

B.they both speak truly of their own feelings.

C.they try to understand each other’s ideas beyond words.

D.they are capable of associating meaning with their words.

2.“I’m letting off some steam” in paragraph 1 means___.

A.I’m just calling your attention.

B.I’m just kidding.

C.I’m just saying the opposite.

D.I’m just giving off some sound.

3.The house-owner’s example shows that he actually means___.

A.the step has been like that for years.

B.he doesn’t think it necessary to fix the step.

C.the condition of the step is only a minor fault.

D.the cost involved in the fixing should be shared.

A.linked to an abnormal amount of assertiveness.

B.seen as one’s habitual pattern of behavior.

Passage 3

Questions 11 to 15 are based on the following passage:

Unlike their American or European counterparts, car salesmen in Japan work hard to get a buyer. Instead of lying lazily around showrooms waiting for customers to drop by, many Japanese car salesmen still go out to get them. They walk wearily along the streets cars door-to-door. New customers are hunted with fruit and cakes on their birthdays. But life is getting tough, and not just because new-car sales are falling.

With more Japanese women (who often control the household budget) going out to work, the salesmen increasingly find nobody at home when they call. That means another visit in the evening or the weekend. Then they face an extra problem: more people, especially the young, prefer to choose a new car from a showroom where they can compare different models.

Even as late as the mid-1980s some 90% of new cars were sold door-to-door. In some rural areas most new cars are still sold this way. But in the big cities more than half the new cars are now sold from showrooms.

Although investing in showrooms is expensive because of the high cost of Japanese land, dealers have little choice. A labor shortage and higher among Japan’s workforce are making it difficult to hire door-to-door salesmen. Most of a Japanese car salesman’s working day is spent doing favors for customers, like arranging insurance or picking up vehicles for servicing, rather than actually selling.

Japan’s doorstep car salesmen are not about to vanish. The personal service they provide is so deep-rooted in Japan that they are likely to operate alongside the glittering new showrooms. The two systems even complement each other. What increasingly happens is that the showroom attracts the interest of a potential buyer, giving the footsore salesmen a firm lead to follow up with a home visit.

11. Japanese car sales usually do not wait at showrooms for customers to drop by; instead, .

A. they sell cars door-to-door

B. they buy presents for their customers

C. they enjoy themselves in recreation centers

D. they go out to do market researches

12. Implied but stated: the competition in car market is .

A. light B. moderate C. fierce D. unfair

13. Young people like to buy a new car .

A. at home B. from a showroom

C. made in the U.S.A. D. made in Japan

14. The squadron of Japanese car salesmen is reducing because of .

A. a labor shortage

B. higher expectations among Japan’s workforce

C. high cost land

D. both A and B

15. Japanese car salesmen to their customers many favors such as .

A. showing them around in an exhibition

B. arranging insurance

C. paying them a visit on weekends

Part I Reading Comprehension

Passage 1

Questions 1 to 5 are based on the following passage:

In Washington D.C., 1600 Pennsylvania Avenue is a very special address. It is the address of the White House, the home of the president of the United States.

Originally the White House was gray and was called the Presidential Palace. It was built from 1792 to 1800. at this time, the city of Washington itself was being built; it was to be the nation’s new capital city. George Washington, the first president, and Pierre Charles L’Enfant, a French engineer, chose the place for the new city. L’Enfant then planned they city. The president’s home was an important part of the plan.

A contest was held to pick a design for the president’s home. An architect named James Hoban won. He designed a large three-story house of gray stone.

President Washington never lived in the President Palace. The first president to live there was John Adams, the second president of the United States, and his wife Mrs. Adams did not really like hew new house. In her letters, she often complained about the cold. Fifty fireplaces were not enough to keep the house warm!

In 1812 the United States and Britain went to war. In 1814 the British invaded Washington. Theu burned many buildings, including the Presidential Palace.

After the war James Hoban, the original architect, partially rebuilt the president’s homes. To cover the marks of the fire, the building was painted white. Before long it became known as the White House.

The White House is one of the most popular tourist attractions in the United States. Every year more than 1.5 million visitors go through the five rooms that are open to the public.

Which is safer-staying at home， traveling to work on public transport， or working in the office? Surprisingly， each of these carries the same risk， which is very low. However， what about flying compared to working in the chemical industry? Unfortunately， the former is 65 times riskier than the latter! In fact， the accident rate of workers in the chemical industry is less than that of almost any of human activity， and almost as safe as staying at home.

The trouble with the chemical industry is that when things go wrong they often cause death to those living nearby. It is this which makes chemical accidents so newsworthy. Fortunately， they are extremely rare. The most famous ones happened at Texas City (1947)，Flixborough (1974)， Seveso (1976)， Pemex (1984) and Bhopal (1984)。

Some of these are always in the minds of the people even though the loss of life was small. No one died at Seveso， and only 28 workers at Flixborough. The worst accident of all was Bhopal， where up to 3，000 were killed. The Texas City explosion of fertilizer killed 552. The Pemex fire at a storage plant for natural gas in the suburbs of Mexico City took 542 lives， just a month before the unfortunate event at Bhopal.

Some experts have discussed these accidents and used each accident to illustrate a particular danger. Thus the Texas City explosion was caused by tons of ammonium nitrate(硝酸铵)，which is safe unless stored in great quantity. The Flixborough fireball was the fault of management， which took risks to keep production going during essential repairs. The Seveso accident shows what happens if the local authorities lack knowledge of the danger on their doorstep. When the poisonous gas drifted over the town， local leaders were incapable of taking effective action. The Pemex fire was made worse by an overloaded site in an overcrowded suburb. The fire set off a chain reaction os exploding storage tanks. Yet， by a miracle， the two largest tanks did not explode. Had these caught fire， then 3，000 strong rescue team and fire fighters would all have died.

1.Chemical accidents are usually important enough to be reported as news because ____.

A.they are very rare

B.they often cause loss of life

C.they always occur in big cities

D.they arouse the interest of all the readers

2.Which of the following statements is true?

B.Traverlling to work on public transport is safer than working at the office.

C.Staying at home is safer than working in the chemical industry.

D.Working in the chemical industry is safer than traveling by air.

3.According to passage， the chemical accident that caused by the fault of management happened at ____.

A.Texas city B.Flixborough C.Seveso D.Mexico City

4.From the discussion among some experts we may coclude that ____.

A.to avoid any accidents we should not repair the facilities in chemical industry

B.the local authorities should not be concerned with the production of the chemical industry

C.all these accidents could have been avoided or controlled if effective measure had been taken

D.natural gas stored in very large tanks is always safe

5.From the passage we know that ammonium nitrate is a kind of ____.

A.natural gas， which can easily catch fire

B.fertilizer， which can't be stored in a great quantity

C.poisonous substance， which can't be used in overcrowded areas

D.fuel， which is stored in large tanks

If the old maxim that the customer is always right still has meaning, then the airlines that ply the world’s busiest air route between London and Paris have a flight on their hands.

The Eurostar train service linking the UK and French capitals via the Channel Tunnel is winning customers in increasing numbers. In late May, it carried its one millionth passenger, having run only a limited service between London, Paris and Brussels since November 1994, starting with two trains a day in each direction to Paris and Brussels. By 1997, the company believes that it will be carrying ten million passengers a year, and continue to grow from there.

From July, Eurostar steps its service to nine trains each way between London and Paris, and five between London and Brussels. Each train carries almost 800 passengers, 210 of them in first class.

The airlines estimate that they will initially lose around 15%-20% of their London-Paris traffic to the railways once Eurostar starts a full service later this year (1995), with 15 trains a day each way. A similar service will start to Brussels. The damage will be limited, however, the airlines believe, with passenger numbers returning to previous levels within two to three years.

In the short term, the damage caused by the 1 million people-levels traveling between London and Paris and Brussels on Eurostar trains means that some air services are already suffering. Some of the major carriers say that their passenger numbers are down by less than 5% and point to their rivals-Particularly Air France-as having suffered the problems. On the Brussels route, the railway company had less success, and the airlines report anything from around a 5% drop to no visible decline in traffic.

The airlines’ optimism on returning traffic levels is based on historical precedent. British Midland, for example, points to its experience on Heathrow Leeds Bradford service which saw passenger numbers fold by 15% when British Rail electrified and modernized the railway line between London and Yorkshire. Two years later, travel had risen between the two destinations to the point where the airline was carrying record numbers of passengers.

1.British airlines confide in the fact that__.

A.they are more powerful than other European airlines.

B.their total loss won’t go beyond a drop of 5% passengers.

C.their traffic levels will return in 2-3 years.

D.traveling by rail can never catch up with traveling by air.

2.The author’s attitude towards the drop of passengers may be described as__.

A.worried.B.delightedC.puzzled.D.unrivaled.

3.In the passage, British Rail (Para 6) is mentioned to__.

A.provide a comparison with Eurostar.

B.support the airlines’ optimism.

C.prove the inevitable drop of air passengers.

D.call for electrification and modernization of the railway.

4.The railway’s Brussels route is brought forth to show that__.

A.the Eurostar train service is not doing good business.

B.the airlines can well compete with the railway.

C.the Eurostar train service only caused little damage.

D.only some airlines, such as Air France, are suffering.

5.The passage is taken from the first of an essay, from which we may well predict that in the following part the author is going to__.

A.praise the airlines’ clear-mindedness.

B.warn the airlines of high-speed rail services.

C.propose a reduction of London/Paris flights.

D.advise the airlines to follow British Midland as their model.
