We are always hearing about road accidents, and when we are in the car we try to drive carefully. But, how many of us take the same degree of care in our homes? A large  36  will tell you the number of accidents that happened in the home is almost the same as those on the  37 .  I don’t pretend to be  38  , but I’ve thought a lot about how and why these accidents happen and what we can do to  39  them.

   One of the most common and most dangerous  40  at home accidents is wrong and careless use  41  electrical equipment. People will continue to use a loose plug or  42  out a plug without first turning off the  43  . In spite of warmng, one  44  carry an electric heater in to the bathroom when he is going to have a  45  . Sometimes on forgets to turn off the power  46  mending a lamp or something  47 . All this can cause accidents. So the  48  about anything that works by electricity is: Switch off before you  49  anything and don’t pretend you know when you actually  50.

   If you’ve got  51  in th house, it’s always best to keep medicines of any kind out of their  52  . otherwise, they may be taken for candies or new kinds of drinds. When there are older eople living with you, you have to take particular  53  in a number of ways in order to make them  54 and happy.

   55  , of course, is always a risk. So, remember to turn it off after cooking. Also, don’t forget to keep the children away from the cooker.

第三部分：閱讀理解（共20小題；每小題2分，滿分40分）

閱讀下列短文，從每題所給的四個選項（A、B、C和D）中，選出最佳選項。

A

The sea has always interested man. From it he can get food, minerals, and treasure. For thousands of years, he could sail on it. But he could not go far beneath its surface.

Man wants to explore deep into the sea. However, he is not a fish. He must breathe air, so he can’t stay under the water’s surface for any length of time. To explore deep water, man faces even more dangers and problems.

    A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases. He can wear a diving suit and have air pumped to him from above. He can carry a tank of air on his back and breathe through a nose and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea. His body is under great pressure.

    When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles. The diver is then suffering from the bends. The bends can cause a diver to double yp in pain. They can even kill him.

56．On the whole, this passage is about ____.

     A．special mixtures of gases in deep sea  

       B．the problems man faces in deep-sea diving

     C．a(chǎn)ir pressure under the surface of sea water

       D．a(chǎn) kind of illness that man suffers in the sea

57．A diver’s body in deep water ____ .

     A．is under great pressure         

       B．is just like that of a fish    

  C．suffers from the bends         

  D．weighs very little

58．The passage does not say so, but it makes you think that ____ .

     A．deep- divers should be in good health

     B．divers explore the deep sea only for treasure

     C．diving under the water too quickly causes a kind of illness.

    D．there is a special mixture of gases under the sea

59．Why does a diver get the bends?

     A．He tries to do exercises under the water.

     B．His diving suit weighs too much.

  C．He comes to the surface too quickly.           

  D．The air in his blood is used up.

60．From the passage we can see that ____ .

     A．the sea began to interest man in the last few years

     B．man is not at home deep in the sea

     C．a(chǎn)ll divers ill get the bends sooner or later

     D．the air in the seawater will kill a diver if he is not careful

B

The U.S. birthrate began to decline in the middle 1950’s, resulting in a smaller college age population starting in the middle 1970’s. something else happened in the 1970’s: the price of oil increased tremendously, driving up the price of almost everything and making Americans aware that their large automobiles used a lot of gasoline. At the same time, foreign car manufacturers had begun to produce small fuel―efficient cars in large quantities for the export market. Suddenly, the large, gas-guzzling American cars were no longer attractive to American buyers, who began buying foreign cars by the thousands. The American automobile industry went into a recession. Thousands of automotive workers were laid off, as were thousands of people in industries indirectly connected with the auto industry. People who are laid off tend to keep what money they have for necessities, like food and housing. They do not have the extra money needed to send their children to college. Their children cannot pay their own college costs, because during a recession they cannot find jobs. High unemployment means that more state funds must be used for social service―unemployment benefits and to aid dependent children, for example―than during more prosperous times. It also means that the states have fewer funds than usual, because people are paying fewer taxes. Institutions of higher education depend on two major sources of income to keep them functioning: tuition from students and funds from the states. At the present time, there are fewer students than in the past and fewer state funs available for higher education. The colleges and universities are in trouble.

61．What is the main idea of this passage?

     A．The rising of oil price drove up the price of everything.

     B．There were many reasons why higher education was in trouble in the 1970’s.       

  C．Birthrate began to decline in the USA in 1950’s.         

  D．High unemployment caused a lot of social problems.

62．The phrase “l(fā)aid off” can best be replaced by which of the following?

     A．poor                                                    B．got rid of         

C．removed                                                   D．unemployed

63．American cars weren’t popular in their domestic markets because of ____ .

     A．small                                                   B．gas-consuming       

C．fuel-efficient                                             D．not attractive

64．The colleges and universities were in trouble because of the following reasons except that ____.

     A．they couldn’t get enough income to keep them running

     B．young people couldn’t afford the tuition fees

     C．keeping them running at the same level would cost much more

  D．social services need more state funds because of the recession

65．All of the following statements are true EXCEPT____ .

  A．young people couldn’t afford their own tuition in the 1970’s

  B．it’s difficult for graduates from colleges to find a job in the 1970’s

C．fewer parents could afford to send their children to college because of the recession in 1970’s        

D．Birthrate dropped in the 1970’s because of the recession

What kind of car will we be driving in 2010? Rather different from the type we know today, with the next 20 years bringing greater change than the past 50．the people who will be designing the models of tomorrow believe that environmental problems may well accelerate the pace of the car’s development. Today they are students on the transport design course at London’s Royal College of Art.

Their vision is of a machine with three wheels instead of four, electrically powered, environmentally clean, and able to drive itself along “intelligent” roads equipped with built-in power supplies. Future cars will pick up their fuel during long journeys from a power source built into the road, or store it in small quantities for travelling in the city.

Instead of today’s seating arrangements―two in front, two or three behind, all facing forward― the 2010 car will have a versatile interior with adults and children in a family circle.

This view of the future car is based on a much more sophisticated road system, with strips built into motorways to supply power to vehicles passing along them, cars will not need drivers, because computers will provide safe driving control and route finding. All the driver will have to do is say where to go and the computer will do the rest. It will become impossible for cars to crash into one another. The technology already exists for the car to become a true automobile.

66．What kind of car will we be driving in 2010?

     A．Three wheeled.                        

       B．Electrically powered.  

     C．With a versatile seating arrangement        

       D．All of the above.

67．How long will a volunteer be required to spend?

     A．A few hours every day.              

       B．A couple of hours each day.

     C．One or two hours every two weeks.    

       D．A few days per week.

68．What does the word “versatile” in Paragraph 3 mean ?

     A．having many different kinds of skill

     B．easily able to change from one direction to another

     C．easily able to change from one kind of activity to another

     D．having many different uses

69．In paragraph 4 “with strips built into motorways to supply power to vehicles passing along them” means “there are many ____ ”.

  A．traffic lights to control the speed of future cars

  B．street posts to indicate directions for drivers

     C．power sources along the street are able to supply power to automobiles

    D．stop marks along the street to stop cars

70．What is the main idea of the passage?

     A．Future cars are completely different from the automobiles we know today.

     B．The design of future cars will be more sophisticated.

     C．Because of the new type of cars, our future environment will become cleaner.            

  D．The road system will become more sophisticated than it is today.

D

Many families in the United States have a larger income now than ever before, but people are finding it difficult to make ends meet anyway. Almost everyone is wondering, “What happens to all my money?” I never seem to have anything left to put away.

Why isn’t a dollar worth as much as it used to be? One dollar is always worth the same amount, that is, 100 cents. But the value of a dollar is how much can buy. The value of money depends on the cost for living. Economists say that the cost of living is the money that a family must pay for the necessities of life such as food, housing or rent, clothes, and medical expenses. For many years now, the cost of living has increased greatly, so the value of the dollar has decreased. When a dollar has a low value, you cannot buy as many things with it.

No one fully understands why the cost of living keeps increasing, but economists believe that workers and producers can make prices go up. As workers earn more money, they have more money to spend, so they demand more goods. If there is a great demand for certain goods, the prices of these goods go up. At the same time, if there’s a shortage of goods, the prices also go up. For example, if everyone wants to buy more and more gas, the price of gas goes up. When companies with hold gas from buyers, they can also make the price of gas go up.

Families need to know what happens to their money. They need to make their income meet the cost of living, so many people plan a family budget. A budget is a list of monthly expenses. If your expenses add up to more than your income, you must find ways to save money. Maybe you’re spending too much on entertainment. Or if you’re spending too much on clothes; you may want to sew your own clothes. Budgeting helps you spend your money wisely as the cost of living increases.

71．What has troubled many families in the United States?

     A．A not-large-enough income.            

B．Nothing is left over to put away.

  C．The increasing cost of living.          

D．A shortage of  certain foods

72．_    ___ determines the value of the dollar.

     A．The government                                  B．The cost of living

     C．The economist                                  D．The bank

73．While the cost of living increases, the value of the dollar____ .

     A．increases to                                     B．decreases        

  C．neither increases nor decreases                   D．seldom decreases

74．When ____ , the prices go up.

     A．demand exceeds supply                         B．supply exceeds demand

     C．demand doesn’t exceed supply                         D．supply equals demand

75．Budgeting helps ____ .

     A．one to make his income meet the cost of living

     B．the government to battle the rising cost of living

     C．merchants to produce more goods  

       D．the workers to earn more money

第四部分：寫作（共兩節(jié)，滿分45分）

第一節(jié)：閱讀表達(dá)（15分）

If you are worried about things and are under a lot of stress at work or school, then you are probably not sleeping well. Worry can keep you awake, tossing and turning in bed until the early hours of the morning when you eventually fall asleep. When you wake up,  you don’t feel refreshed, but tired and worn out and unable to face a new day.

Dr. Henry Winkle, in a recent newspaper article entitled Stress and Sleep, indicates that _________ . Dr. Winkle says, “The more we worry, the less we sleep, the more we are unable to deal with stress. If we can find a way to get a good night’s sleep,” he adds, “we can often find the energy to deal with what’s worrying us”.

So, what is a good night’s sleep? Research shows that the amount of sleep which people need in order to keep healthy varies a lot. Seven hours in about the average amount, though strangely enough, sleeping longer often gives you a headache instead of making you feel more refreshed.

Dr. Winkle believes that preparing for sleeping is important. People who work late should try to give themselves a short break and do something restful before going to bed. This could be watching TV or listening to music. Doing some exercise earlier in the day should help you to feel physically as well as mentally tired. A bedtime drink can also help, but coffee or tea should be avoided as they contain caffeine and will keep you awake. “When you put the light out,” Dr. Winkle says, “concentrate on relaxing your muscles, working slowly up from your feet, and you’ll be asleep before you know it.”

76．What is the best title of the passage? (Please answer within 10 words.)

We are always hearing about road accidents, and when we are in the car we try to drive carefully. But, how many of us take the same degree of care in our homes? A large  36  will tell you the number of accidents that happened in the home is almost the same as those on the  37 .  I don’t pretend to be  38  , but I’ve thought a lot about how and why these accidents happen and what we can do to  39  them.

   One of the most common and most dangerous  40  at home accidents is wrong and careless use  41  electrical equipment. People will continue to use a loose plug or  42  out a plug without first turning off the  43  . In spite of warmng, one  44  carry an electric heater in to the bathroom when he is going to have a  45  . Sometimes on forgets to turn off the power  46  mending a lamp or something  47 . All this can cause accidents. So the  48  about anything that works by electricity is: Switch off before you  49  anything and don’t pretend you know when you actually  50.

   If you’ve got  51  in th house, it’s always best to keep medicines of any kind out of their  52  . otherwise, they may be taken for candies or new kinds of drinds. When there are older eople living with you, you have to take particular  53  in a number of ways in order to make them  54 and happy.

   55  , of course, is always a risk. So, remember to turn it off after cooking. Also, don’t forget to keep the children away from the cooker.

The sea has always interested man. From it he can get food, minerals, and treasure. For thousands of years, he could sail on it. But he could not go far beneath its surface.

Man wants to explore deep into the sea. However, he is not a fish. He must breathe air, so he can’t stay under the water’s surface for any length of time. To explore deep water, man faces even more dangers and problems.

    A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases. He can wear a diving suit and have air pumped to him from above. He can carry a tank of air on his back and breathe through a nose and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea. His body is under great pressure.

    When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles. The diver is then suffering from the bends. The bends can cause a diver to double yp in pain. They can even kill him.

56．On the whole, this passage is about ____.

     A．special mixtures of gases in deep sea  

       B．the problems man faces in deep-sea diving

     C．a(chǎn)ir pressure under the surface of sea water

       D．a(chǎn) kind of illness that man suffers in the sea

57．A diver’s body in deep water ____ .

     A．is under great pressure         

       B．is just like that of a fish    

  C．suffers from the bends         

  D．weighs very little

58．The passage does not say so, but it makes you think that ____ .

     A．deep- divers should be in good health

     B．divers explore the deep sea only for treasure

     C．diving under the water too quickly causes a kind of illness.

    D．there is a special mixture of gases under the sea

59．Why does a diver get the bends?

     A．He tries to do exercises under the water.

     B．His diving suit weighs too much.

  C．He comes to the surface too quickly.           

  D．The air in his blood is used up.

60．From the passage we can see that ____ .

     A．the sea began to interest man in the last few years

The U.S. birthrate began to decline in the middle 1950’s, resulting in a smaller college age population starting in the middle 1970’s. something else happened in the 1970’s: the price of oil increased tremendously, driving up the price of almost everything and making Americans aware that their large automobiles used a lot of gasoline. At the same time, foreign car manufacturers had begun to produce small fuel―efficient cars in large quantities for the export market. Suddenly, the large, gas-guzzling American cars were no longer attractive to American buyers, who began buying foreign cars by the thousands. The American automobile industry went into a recession. Thousands of automotive workers were laid off, as were thousands of people in industries indirectly connected with the auto industry. People who are laid off tend to keep what money they have for necessities, like food and housing. They do not have the extra money needed to send their children to college. Their children cannot pay their own college costs, because during a recession they cannot find jobs. High unemployment means that more state funds must be used for social service―unemployment benefits and to aid dependent children, for example―than during more prosperous times. It also means that the states have fewer funds than usual, because people are paying fewer taxes. Institutions of higher education depend on two major sources of income to keep them functioning: tuition from students and funds from the states. At the present time, there are fewer students than in the past and fewer state funs available for higher education. The colleges and universities are in trouble.

C．removed                                                   D．unemployed

63．American cars weren’t popular in their domestic markets because of ____ .

     A．small                                                   B．gas-consuming

What kind of car will we be driving in 2010? Rather different from the type we know today, with the next 20 years bringing greater change than the past 50．the people who will be designing the models of tomorrow believe that environmental problems may well accelerate the pace of the car’s development. Today they are students on the transport design course at London’s Royal College of Art.

Their vision is of a machine with three wheels instead of four, electrically powered, environmentally clean, and able to drive itself along “intelligent” roads equipped with built-in power supplies. Future cars will pick up their fuel during long journeys from a power source built into the road, or store it in small quantities for travelling in the city.

Instead of today’s seating arrangements―two in front, two or three behind, all facing forward― the 2010 car will have a versatile interior with adults and children in a family circle.

This view of the future car is based on a much more sophisticated road system, with strips built into motorways to supply power to vehicles passing along them, cars will not need drivers, because computers will provide safe driving control and route finding. All the driver will have to do is say where to go and the computer will do the rest. It will become impossible for cars to crash into one another. The technology already exists for the car to become a true automobile.

66．What kind of car will we be driving in 2010?

     A．Three wheeled.                        

       B．Electrically powered.  

     C．With a versatile seating arrangement        

       D．All of the above.

67．How long will a volunteer be required to spend?

     A．A few hours every day.              

       B．A couple of hours each day.

     C．One or two hours every two weeks.    

       D．A few days per week.

68．What does the word “versatile” in Paragraph 3 mean ?

     A．having many different kinds of skill

     B．easily able to change from one direction to another

     C．easily able to change from one kind of activity to another

     D．having many different uses

69．In paragraph 4 “with strips built into motorways to supply power to vehicles passing along them” means “there are many ____ ”.

  A．traffic lights to control the speed of future cars

  B．street posts to indicate directions for drivers

     C．power sources along the street are able to supply power to automobiles

    D．stop marks along the street to stop cars

70．What is the main idea of the passage?

     A．Future cars are completely different from the automobiles we know today.

     B．The design of future cars will be more sophisticated.

     C．Because of the new type of cars, our future environment will become cleaner.            

  D．The road system will become more sophisticated than it is today.

Many families in the United States have a larger income now than ever before, but people are finding it difficult to make ends meet anyway. Almost everyone is wondering, “What happens to all my money?” I never seem to have anything left to put away.

Why isn’t a dollar worth as much as it used to be? One dollar is always worth the same amount, that is, 100 cents. But the value of a dollar is how much can buy. The value of money depends on the cost for living. Economists say that the cost of living is the money that a family must pay for the necessities of life such as food, housing or rent, clothes, and medical expenses. For many years now, the cost of living has increased greatly, so the value of the dollar has decreased. When a dollar has a low value, you cannot buy as many things with it.

No one fully understands why the cost of living keeps increasing, but economists believe that workers and producers can make prices go up. As workers earn more money, they have more money to spend, so they demand more goods. If there is a great demand for certain goods, the prices of these goods go up. At the same time, if there’s a shortage of goods, the prices also go up. For example, if everyone wants to buy more and more gas, the price of gas goes up. When companies with hold gas from buyers, they can also make the price of gas go up.

Families need to know what happens to their money. They need to make their income meet the cost of living, so many people plan a family budget. A budget is a list of monthly expenses. If your expenses add up to more than your income, you must find ways to save money. Maybe you’re spending too much on entertainment. Or if you’re spending too much on clothes; you may want to sew your own clothes. Budgeting helps you spend your money wisely as the cost of living increases.

71．What has troubled many families in the United States?

     A．A not-large-enough income.            

B．Nothing is left over to put away.

  C．The increasing cost of living.

72．_    ___ determines the value of the dollar.

     A．The government                                  B．The cost of living

     C．The economist                                  D．The bank

73．While the cost of living increases, the value of the dollar____ .

     A．increases to                                     B．decreases        

  C．neither increases nor decreases                   D．seldom decreases

74．When ____ , the prices go up.

     A．demand exceeds supply                         B．supply exceeds demand

     C．demand doesn’t exceed supply                         D．supply equals demand

75．Budgeting helps ____ .

     A．one to make his income meet the cost of living

     B．the government to battle the rising cost of living

If you are worried about things and are under a lot of stress at work or school, then you are probably not sleeping well. Worry can keep you awake, tossing and turning in bed until the early hours of the morning when you eventually fall asleep. When you wake up,  you don’t feel refreshed, but tired and worn out and unable to face a new day.

Dr. Henry Winkle, in a recent newspaper article entitled Stress and Sleep, indicates that _________ . Dr. Winkle says, “The more we worry, the less we sleep, the more we are unable to deal with stress. If we can find a way to get a good night’s sleep,” he adds, “we can often find the energy to deal with what’s worrying us”.

So, what is a good night’s sleep? Research shows that the amount of sleep which people need in order to keep healthy varies a lot. Seven hours in about the average amount, though strangely enough, sleeping longer often gives you a headache instead of making you feel more refreshed.

Dr. Winkle believes that preparing for sleeping is important. People who work late should try to give themselves a short break and do something restful before going to bed. This could be watching TV or listening to music. Doing some exercise earlier in the day should help you to feel physically as well as mentally tired. A bedtime drink can also help, but coffee or tea should be avoided as they contain caffeine and will keep you awake. “When you put the light out,” Dr. Winkle says, “concentrate on relaxing your muscles, working slowly up from your feet, and you’ll be asleep before you know it.”
