            Many countries are working to improve railroad passenger service along heavily traveled routes that run between cities. Because they use less energy perpassenger than any other means of transportation, modern railroads could help save the world’s energy resources(資源)and reduce air pollution.

            The MLV is a new type of high-speed vehicle, which carries people from one city to another. An MLV track is made up of a single rail that lies under the centre of the train, but the train doesn't touch the track when it is moving. MLV’s are powered by electric motors. A powerful magnetic(磁的)force, produced by magnets in both the motor and the track itself. Levitates(懸。the train. This magnetic force holds the train about 15 cm above the rail and moves it forward. The train, which was designed by French, German, and Japanese engineers, is expected to travel more than 480 km per hour.

          1An MLV is a sort of ______.

          [  ]

          Astrong magnitic force

          Bspecial energy resource

          Cmodern passenger train

          Dstraight railroad

          2When an MLV is running, there is powerful magnetic force in ______.

          [  ]

          Athe motor only

          Bthe track only

          Cnot only the motor but also the track

          Dneither the motor nor the track

          3From the sentence”This magnetic force holds the train about 15 cm above the rail and moves it forward.” We know that when moving forward, an MLV ______.

          [  ]

          Ais lifted above the track

          Btouches the rail all the time

          Cleaves the track from time to time

          Dfloats high above the rail

          4Which of the following is NOT TRUE?

          [  ]

          AAn MLV runs much faster than an ordinary train.

          BEngineers designed the MLV in order to improve railroad goods service.

          CModern passenger service could help save energy resources.

          DAn MLV doesn’t produce waste gases.

          5The reason to improve railroad passenger service doesn't lie in that ______.

          [  ]

          Aenergy resources ought to be saved

          Bpeople want to reduce air pollution

          Ctransportation problems remain unsettled

          Dmore and more passengers don't want to travel by train

          語篇理解

            Books are for reading, but man must bring to their reading a desire to learn and a power of absorbing. Reading should be active, not passive.

            When students first go to a library, they may be at a loss as to what to read of all the different subjects. Well, Bacon tells you to “l(fā)ook at weak places in your armor(盔甲)”, and shows you how to fill up the blanks(空白)in your knowledge. On the other hand ,it is no good just trying to fill your mind with Knowledge. Knowledge in itself is often useless. A mind filled with too much knowledge is like a room too full of furniture; a man cannot walk about freely in it, and look out of the windows. It is much better to concentrate on a few subjects which interest you and to deal lightly with the others than to march heavily through the whole range of learning, like a silly tourist(旅游者)going through a museum and not missing a single object. If you try to master every subject you may become very wise, but you will be very lonely and you will probably lose all your friends. So you must learn to pick and choose , and you must also learn to look here and there in a library like a camel eating grass on the grassland. If you watch it eating, you will see that although he is supposed to be one of the most stupid animals in the world, he has at least one of the qualities of the cultured man, the power to pick and choose. A student looking for mental food in a library should take the camel as his model.

          1The writer thinks that one must ______.

          [  ]

          Aread as many books as he can

          Btry to read books on all the different subjects

          Conly read books on subjects that interest him

          Dread and absorb a lot

          2A cultured man is similar(相同)to a camel because ______.

          [  ]

          Aneither of them is interested in knowledge

          Bthe man reads books as much as a camel eats grass

          Cneither of them can be considered wise

          Dboth of them have the ability to select

          3The term “mental food” at the end of the passage refers to ______.

          [  ]

          Abooks   Bgrassland

          Cbrain   Dsubjects

          4In the second paragraph the writer mainly discusses ______.

          [  ]

          Ahow to compare furniture with books

          Bhow to select reading materials

          Chow to avoid missing anything interesting in the library.

          Dwhy books must be absorbed

          5The writer thinks that it is ______ to try to master every subject.

          [  ]

          Anecessary   Bpossible

          Cnot good    Dnot interesting

            The first man to step out of a spaceship and “walk” in outer space was a Russian, Alexia LeonAnd Edward White was the first American to take a “space walk”It is very interesting to imagine what it is like to take a “walk” in space

            How did these two astronauts walk in space? Well, they did not actually walk in space with their feetThey floated thereThat is because in space there is no earth under your feet to walk onSpace is emptyThere is nothing around you and nothing under your feet at allSo how is it possible to walk with your feet? You can only floatWhat is more, as there is no up or down in space, to float on your stomach, or on your back, or on your head, all feels the sameIt does not make any difference to you whether you look at the earth upside down or right side up

            A good way to help you to float in space is to use a jet gunIt pushes you much as a jet engine pushes a planeIt also helps you control your directionAnd in order to keep you from moving too far away from your spaceship, you have to have a line with you and tie its other end to the spaceship, because it would be so easy to move too fast and drift so far into space that it would be difficult to get back to the spaceshipThis line also carries oxygen for you to breathe, and messages from inside the spaceship and from the earth

            The first two men to work outside of a spaceship have already enjoyed “space walking”Their experiments are the first step toward the building of space stations for the exploration of outer space

          1This passage mainly tells us ______

          [  ]

          Ahow people walk in outer space

          Bhow people are sent into outer space

          Chow people get back onto the earth from space

          Dhow people build space stations

          2Alexia Leon and Edward White were both ______

          [  ]

          ARussians    BAmericans

          Cspacemen    DEnglishmen

          3In fact, Leon and Edward White both ______

          [  ]

          Awalked    Bran

          Cjumped    Dfloated

          4A jet gun is used to ______

          [  ]

          Apush a plane up into the sky

          Bhelp an astronaut float in space

          Chelp an astronaut control the direction in space

          Dboth B and C

          5In space the special line is used to carry oxygen for people to breathe and messages from the spaceship or the earth besides ______

          [  ]

          Akeeping people from moving too far away from the spaceship

          Bdrifting so far into space

          語篇理解

            Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experiences? Strangely enough, the answer to both these questions is yesTo some extent(從某種程度上說) our intelligence(智力) is given to us at birth, and no amount of special education can make a genius(天才) out of a child born with low intelligenceOn the other hand, a child who lives in a boring(乏味的) environment(環(huán)境) will develop his intelligence less than one who lives in rich and varied surroundingsThus the limits of a person’s intelligence are fixed at birth, but whether of not he reaches those limits will depend on his environmentThis view, now held by most experts, can be supported in a number of ways

            It is easy to show that intelligence is to some extent something we are born withThe closer the blood relationship between two people, the closer they are likely to be in intelligenceThus if we take two unrelated people at random(隨意地) from the population, it is likely that their degrees of intelligence will be completely differentIf on the other hand we take two identical twins(雙胞胎) they will very likely be as intelligent as each otherRelations like brothers and sisters, parents and children, usually have similar(相同的) intelligence, and this clearly suggests that intelligence depends on birth

            Imagine now that we take two identical twins and put them in different environmentsWe might send one, for example, to a university and the other to a factory where the work is boringWe would soon find differences in intelligence developing, and this indicates(表明) that environment as well as birth plays a partThis conclusion is also suggested by the fact that people who live in close contact with each other(聯(lián)系), but who are not related at all, are likely to have similar degrees of intelligence

          1The writer is in favor of the view that man's intelligence is given to him ______

          [  ]

          Aat birth

          Bthrough education

          Cboth at birth and through education

          Dneither at birth nor through education

          2If a child is born with low intelligence, he can ______

          [  ]

          Anever become a genius

          Bstill become a genius if he should be given special education

          Cexceed(超過) his intelligence limits in rich surroundings

          Dnot reach his intelligence in his life

          3In the second paragraph “if we take two unrelated people at random from the population” means if we ______

          [  ]

          Apick up any two persons

          Bchoose two persons who are relatives

          Ctake out two different persons

          Dchoose two persons with different intelligence

          4The example of the twins going to a university and to a factory separately is to show ______

          [  ]

          Athe importance of their intelligence

          Bthe role of environment on intelligence

          Cthe importance of their positions

          Dthe part that birth plays

            The old man rested in the sun.He thought of his violin which he loved dearly.He remembered buying it in 1931 from a stranger who needed money.He had paid him 250

            “Uncle Sanchez, a telegram(電報(bào))for you!”a boy shouted.

            Slowly the man opened it.First he smiled,then he laughed.

            “What is it?”the boy asked.

            “From the American who saw my violin at Christmas.”He remembered that the stranger had looked inside the violin as if he were looking for gold.”He says my violin was made by Stradivari.He will buy it for 100000.”

            Sanchez was not the first person to learn that his violin was a treasure(財(cái)寶).He is just one of the most recent.Stories like this could be told in different parts of the world.Some of Stradivari’s violins have been carefully protected,others have been harmed by carelessness.

            Almost nothing is known of Stradivari’s early life.But we do know he was born in a small village in Italy in 1644.As a boy of twelve,he began to learn violin making from Amati,Who was famous all over Europe for his fine violins.However, it was not until after Amati’s death in 1684 that Stradivari began making his own violins.He never made poor violins,but he made some that were much better than all the others.Luckily Stradivari’s great skill was noticed.Top prices were paid for his works from the time he began to sell them.

            Today it is thought that Stradivari made violins that are better than any made ever since.Many of the world’s best violinists have chosen Stradivari’s violins.But few now can have a lot of money to collect them.some of the most beautiful are kept in museums.There,they can be seen by everyone or lent to famous artists for concerts.

          1Who was the maker of the violin owned by Sanchez?

          [  ]

          AAmati taught Stradivari to make violins

          BStradivari was Amati’s workmate

          CAmati was also a well-known violinist

          DAmati did not permit Stradivari to play his own violins

          5Which of the follwing is NOT true according to the passage?

          [  ]
