Leonardo Da Vinci made drawings of submarines (潛艇) . but he did not show his drawings to other people. He said that there was “too much badness in the hearts of men.” He wrote, “If I give them my secret, they will use it for war in the depths (深度) of the sea.”

Now both the Americans and the Russians have more than 200 nuclear (核能的) submarines. These submarines carry nuclear missiles (導彈) . many missiles can go 4800 kilometres. The submarines can fire them from under the water. But now planes and satellites can “see” the heat of these submarines below the sea. What is the answer?

Countries can build missile stations on the seabed. They can build them secretly near the coasts of the other countries. Will there be war unedr the sea? Will there be war in the deep valleys and high mountains of the seabed? Nobody can win that war. If life, if fish and plants and animals die , then man will die too.

Keeping the sea alive means keeping man alive. Will we kill the sea with pollution and war or will we farm the sea and life?

Cell phones, pagers, laptop cimputers, and personal digital (數(shù)字) assistants are being used, bringing increased productivity and efficiency to millions of users. A survery, however, suggests that too much information may be getting out of hand. From palmtop computer e-mail to cell phone voice mail, controlling these ways of receiving information is becoming a serious management problem for the people who use them.

People may feel overwhelmed, leading them to become stressed and have less time to spend with their family and friends.

Thus, it is mecessary to set up an organizing system for people to handle the electronic information. When people master the digital organization, it will greatly and improve both their professional and personal lives. Without an organizing system, however, people have to spend a large amount of time looking for misplaced information.

64.What’s the main purpose of the text?

       A、Tell people the advantages of modern devices (設(shè)備) .

B、Tell people to set up an organizing system to handle information.

C、Complain (抱怨) of the modern devices.

D、Tell people the disadvantages of modern devices.

65.How can people get information?

      A、Using cell phones, pagers, laptop computers and personal digital ssistants.

B、Reading books and magazines.

C、writing letters and attending meetings.         D、By phone.

66.What does the phrase “get out of hand” mean in Sentence 2 of Paragraph 1?

       A、get out of control B、get impossible C、get too much    D、get useless

67.What are the advantages of such an orgainzing system?

       A、It can help people to spend time looking for misplaced information.

B、It can help people to handle the electronic information.

C、It can simplify and improve both their professional and personal lives.

D、Both B and C.

Foods quickly spoil and break down if they are not stored correctly. Heat and damp encourage an increase of micro-organisms (微生物) ,and sunlight can destroy the vitamins in such foods as milk. Therefore, most foods should be stored in a cool, dark, dry place.

Some foods go had quickly, such as meat, eggs, and milk. They should be stored in a refrigerator or in the underground basement of a house.

Dry goods, such as flour and rice, should be kept a slightly higher temperathure than foods that go bad quickly. A temperature of 15℃ is ideal (理想的). In Britain and northem European countries this means that the room in which dry goods are stored should share the general heating of the house. The room should also be well aired and, above all, dry. Damp very quickly causes the growth of the green molds (霉) . These molds often grow on cheese if it is not stored properly.

Fruits and vegetables need cool, damp, but frost-proof (防霜凍的) conditions. Therefore, an underground basement usually makes an excellent storage place. If the central heating until is located in the basement, however, it will not be ideal unless the unit and the pipes do not give out any heat.

Foodstuffs (食料、糧食) do not break down quickly. If correctly stored, they should keep for quite long periods of time. Thus, salt and sugar will keep for about two years; tinned meat goods, such as beef and chicken, for about eighteen months; flour and other dry goods, for about a year. Freezing the foodstuffs that spoil easily preserves them for much longer than is otherwise possible. But even frozen foods do not keep their food value of their taste for ever. As a general rule, meat should be cooked and eaten within a year afrer it is frozen; fish, within six to ten months; fruits and vegetables, within three to six months.

68.According to the author, why should food be stored in a dark place?

       A、Such a place is usually cool and well aired.

B、The producer of the food requires us to do so.

C、Heat causes the growth of the micro-organisms in the food.

D、The vitamins in some food can be ruined by runlight.

69.In northn European countries the general heating of the house can keep the ideal temperature for         .

       A、the growth of the green molds        B、the processing of cheese

C、the storage of flour and rice            D、the operation of refrigerators

70.How many possible places have been recommended for storing fruits and vegetables?

       A、One .            B、Two.             C、Three.           D、Four.

71.What is the main purpose of the last paragraph?

       A、To inform the reader about the lengths of time that foodstuffs will keep.

B、To show how to keep the food value of frozen foods.

C、To tell us meat should be cooked and eaten within a vear.

D、To describe the disadvantages of frozen foods.

It is said that matheatics is the base of all other sciences, and that arethmetic (算術(shù);計算) , the science of numbers is the base of mathematics. Numbers consist of whole number which are formed by the digits 0 ,1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 and 9 and by combinatics of them by three digits. Parts of numbers smaller than I are sometimes expressed in terms of fractions (分數(shù)) ,but in scientific usage they are given as decimals (小數(shù)) . This is because it is easier to perform the various mathe-matical operations if decimals are used instead of fractions.

The decimal, or ten-scale, system is used for scientific purposes throughout the world. It is even accepted in countries whose national systems of weights and measurements are based upon other scales. The other scale in general use nowadays is the binary, or two-scales. In such a scale (進位) , numbers are expressed by combination of only two digits, 0 and 1. Thus, 2 is expressed as 010, 3 is given as 011, 4 is represented as 100, etc. This scale is perfectly adapted to the “off-on” pulses of electricity, so it is widely used in electronic computers. It is because of its simplicity that the scale is often called “the lazy schoolboy’s dream”!

Other branches of mathematics such as algebra (代數(shù)) and geometry are also extensively used in many sciences and even in some areas of philosophy. More specialized extension, such as probability theory and group theory, are now applied to an increasing number of activities, ranging from economics and the design of experimernts to war and politics.

Finally, a knowledge of statistics is required by every type of scientists for the analysis of data. Moreover, even an elementary knowledge of this branch of mathematics is rufficient to enable the journalist to avoid misleading his readers. It is also useful in helping the ordinary citizen detect the attempts attempts which are constantly made to deceiven him.

72.What is the passage mainly about?

       A、The importance of statistics (統(tǒng)計學) . 

B、The branches of mathematics and their applications.

C、The new development of arithmetic.

D、The relation of mathematics to other sciences.

73.Which of the following descriptions best applied to the decimal system?

       A、The base of all national systems of weights and measurements.

B、The number system based on whole numbers and fractions.

C、The widely adopted number system in science today.

D、The basic number system for computer work.

74.According to the passage, why is the binary system often called “the lazy schoolboy’s dream”?

       A、Arithmetic operations in this system are relatively (相對地) easy.

B、The schoolboy likes the digital computers.

C、This system is not required to be learned in schoos.

D、The two-scale mathematical operations are interesting.

75.According to the passage, which of the following statements about philosophy (哲學) is true?

A、Mathematics in the modern world is advancing faster than philosophy.

B、In natural sciences more areas of philosophy are being used than ever before.

C、Philosophy has made great contributions to the progress of algebra and geometry.

D、Mathematical knowledge plays an important role in some fields of philosophy.

    Leonardo Da Vinci made drawings of submarines (潛艇) . but he did not show his drawings to other people. He said that there was “too much badness in the hearts of men.” He wrote, “If I give them my secret, they will use it for war in the depths (深度) of the sea.”

    Now both the Americans and the Russians have more than 200 nuclear (核能的) submarines. These submarines carry nuclear missiles (導彈) . many missiles can go 4800 kilometres. The submarines can fire them from under the water. But now planes and satellites can “see” the heat of these submarines below the sea. What is the answer?

    Countries can build missile stations on the seabed. They can build them secretly near the coasts of the other countries. Will there be war unedr the sea? Will there be war in the deep valleys and high mountains of the seabed? Nobody can win that war. If life, if fish and plants and animals die , then man will die too.

    Keeping the sea alive means keeping man alive. Will we kill the sea with pollution and war or will we farm the sea and life?

    60.Why did Leonardo Da Vinci not show his drawings of submarines to other people?

    Cell phones, pagers, laptop cimputers, and personal digital (數(shù)字) assistants are being used, bringing increased productivity and efficiency to millions of users. A survery, however, suggests that too much information may be getting out of hand. From palmtop computer e-mail to cell phone voice mail, controlling these ways of receiving information is becoming a serious management problem for the people who use them.

    People may feel overwhelmed, leading them to become stressed and have less time to spend with their family and friends.

    Thus, it is mecessary to set up an organizing system for people to handle the electronic information. When people master the digital organization, it will greatly and improve both their professional and personal lives. Without an organizing system, however, people have to spend a large amount of time looking for misplaced information.

    64.What’s the main purpose of the text?

           A、Tell people the advantages of modern devices (設(shè)備) .

    B、Tell people to set up an organizing system to handle information.

    C、Complain (抱怨) of the modern devices.

           A、It can help people to spend time looking for misplaced information.

    B、It can help people to handle the electronic information.

    C、It can simplify and improve both their professional and personal lives.

    D、Both B and C.

    D

    Foods quickly spoil and break down if they are not stored correctly. Heat and damp encourage an increase of micro-organisms (微生物) ,and sunlight can destroy the vitamins in such foods as milk. Therefore, most foods should be stored in a cool, dark, dry place.

    Some foods go had quickly, such as meat, eggs, and milk. They should be stored in a refrigerator or in the underground basement of a house.

    Dry goods, such as flour and rice, should be kept a slightly higher temperathure than foods that go bad quickly. A temperature of 15℃ is ideal (理想的). In Britain and northem European countries this means that the room in which dry goods are stored should share the general heating of the house. The room should also be well aired and, above all, dry. Damp very quickly causes the growth of the green molds (霉) . These molds often grow on cheese if it is not stored properly.

    Fruits and vegetables need cool, damp, but frost-proof (防霜凍的) conditions. Therefore, an underground basement usually makes an excellent storage place. If the central heating until is located in the basement, however, it will not be ideal unless the unit and the pipes do not give out any heat.

    Foodstuffs (食料、糧食) do not break down quickly. If correctly stored, they should keep for quite long periods of time. Thus, salt and sugar will keep for about two years; tinned meat goods, such as beef and chicken, for about eighteen months; flour and other dry goods, for about a year. Freezing the foodstuffs that spoil easily preserves them for much longer than is otherwise possible. But even frozen foods do not keep their food value of their taste for ever. As a general rule, meat should be cooked and eaten within a year afrer it is frozen; fish, within six to ten months; fruits and vegetables, within three to six months.

    68.According to the author, why should food be stored in a dark place?

           A、Such a place is usually cool and well aired.

    B、The producer of the food requires us to do so.

    C、Heat causes the growth of the micro-organisms in the food.

    D、The vitamins in some food can be ruined by runlight.

    69.In northn European countries the general heating of the house can keep the ideal temperature for         .

           A、the growth of the green molds        B、the processing of cheese

    C、the storage of flour and rice            D、the operation of refrigerators

    70.How many possible places have been recommended for storing fruits and vegetables?

           A、One .            B、Two.             C、Three.           D、Four.

    71.What is the main purpose of the last paragraph?

           A、To inform the reader about the lengths of time that foodstuffs will keep.

    B、To show how to keep the food value of frozen foods.

    C、To tell us meat should be cooked and eaten within a vear.

    D、To describe the disadvantages of frozen foods.

    It is said that matheatics is the base of all other sciences, and that arethmetic (算術(shù);計算) , the science of numbers is the base of mathematics. Numbers consist of whole number which are formed by the digits 0 ,1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 and 9 and by combinatics of them by three digits. Parts of numbers smaller than I are sometimes expressed in terms of fractions (分數(shù)) ,but in scientific usage they are given as decimals (小數(shù)) . This is because it is easier to perform the various mathe-matical operations if decimals are used instead of fractions.

    The decimal, or ten-scale, system is used for scientific purposes throughout the world. It is even accepted in countries whose national systems of weights and measurements are based upon other scales. The other scale in general use nowadays is the binary, or two-scales. In such a scale (進位) , numbers are expressed by combination of only two digits, 0 and 1. Thus, 2 is expressed as 010, 3 is given as 011, 4 is represented as 100, etc. This scale is perfectly adapted to the “off-on” pulses of electricity, so it is widely used in electronic computers. It is because of its simplicity that the scale is often called “the lazy schoolboy’s dream”!

    Other branches of mathematics such as algebra (代數(shù)) and geometry are also extensively used in many sciences and even in some areas of philosophy. More specialized extension, such as probability theory and group theory, are now applied to an increasing number of activities, ranging from economics and the design of experimernts to war and politics.

    Finally, a knowledge of statistics is required by every type of scientists for the analysis of data. Moreover, even an elementary knowledge of this branch of mathematics is rufficient to enable the journalist to avoid misleading his readers. It is also useful in helping the ordinary citizen detect the attempts attempts which are constantly made to deceiven him.

    72.What is the passage mainly about?

           A、The importance of statistics (統(tǒng)計學) . 

    B、The branches of mathematics and their applications.

    C、The new development of arithmetic.

    D、The relation of mathematics to other sciences.

    73.Which of the following descriptions best applied to the decimal system?

           A、The base of all national systems of weights and measurements.

    B、The number system based on whole numbers and fractions.

    C、The widely adopted number system in science today.

    D、The basic number system for computer work.

    74.According to the passage, why is the binary system often called “the lazy schoolboy’s dream”?

           A、Arithmetic operations in this system are relatively (相對地) easy.

    B、The schoolboy likes the digital computers.

    C、This system is not required to be learned in schoos.

    D、The two-scale mathematical operations are interesting.

    75.According to the passage, which of the following statements about philosophy (哲學) is true?

    A、Mathematics in the modern world is advancing faster than philosophy.

    B、In natural sciences more areas of philosophy are being used than ever before.

    C、Philosophy has made great contributions to the progress of algebra and geometry.

    D、Mathematical knowledge plays an important role in some fields of philosophy.
