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?

A.Working at the office is safer than staying at home.

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

Part I Reading Comprehension

Directions: In this part there are four passages. Each passage is followed by four comprehension questions. Read the passage and answer the questions. Then mark your answer on the Answer Sheet.

Passage 1

Questions 1 to 5 are based on the following passage:

Ask three people to look the same window at a busy street corner and tell you what they see. Chances are you will receive three different answers. Each person sees the same scene, but each perceives something different about it.

Perceiving goes on in our minds. Of the three people who look out the window, one may say that he sees a policeman giving a motorist a ticket. Another may say that he sees a rush-hour traffic jam at the intersection. The third may tell you that he sees a woman trying to cross the street with four children in tow. For perception is the mind’s interpretation of what the senses—in this case our eyes—tell us.

Many psychologists today are working to try to determine just how a person experiences or perceives the world around him. Using a scientific approach, these psychologists set up experiments in which they can control all of the factors. By measuring and charting the results of many experiments, they are trying to find out what makes different people perceive totally different things about the same scene.

1. Seeing and perceiving are .

A. the same action

B. two separate actions

C. two actions carried on entirely by eyes

D. several actions that take place at different times

2. Perceiving is an action that takes place .

A. in our eyes

B. only when we think very hard about something

C. only under the direction of a psychologist

D. in every person’s mind

3. People perceive different things about the same scene because .

A. they see different things B. some have better eyesight

C. they cannot agree about things D. none of these

4. Which of the following is implied but not stated in the passage?

A. Psychologists do not yet know people see.

B. The experiments in which all factors are controlled are better.

C. The study of perception is going on now.

D. Perception does not involve psychological factors.

5. The best title for this selection is .

A. How We See

B. Learning about Our Minds through Science

C. What Psychologists Perceive

D. How to Because an Experimental Psychologist

You’d better let me know as soon as there is a(n)____position in the branch office.

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.
