       The Migration of Birds

   Here is a scientific experiment on the homing of birds, the fact of which are quite certain. A few years ago seven swallows were caught near their nests at Bremen in Germany. They were marked with a red dye on some of their white feathers, so that they could easily been seen. Then they were taken by plane to Croydon, near London. This is a distance of 400 miles.

   Then the seven swallows were set free at Croydon. Five of them flew back to their nests at Bremen. How did the birds find their way on that long journey, which they had never made before? That is the great puzzle. It is no good saying that the swallows have a sense of direction. These are just words and explain nothing. We want to know exactly what senses the animals use to find their way, how they know in which direction to go until they can see familiar landmarks. Unfortunately practically no scientific experiments have yet been made on this question.

   Perhaps migrating birds are the greatest mystery of all. Swallows leave England in August and September, and they fly to Africa, where they stay during our winter. The swallows return to England in the late summer for the south. A lot has been found about the journeys of migrating birds by marking the birds with aluminum rings put on one leg. An address and a number is put on the ring.

   Swallows from England go as far as South Africa and as many as fourteen birds, marked with rings in England, have been caught again in South Africa. From England to South Africa is a journey of 6,000 miles. And the birds not only return from Africa to England next spring, but often they come back to the nests in the very same house where they nested the year before.

17.The seven swallows were marked on some of their feathers because       .

A.they would be taken away by plane

B.they would be free in London

C.Croydon was 400 miles away

D.they could easily be seen for the red colour

18.Which of the following is true?       .

B.No one knows why the swallows can fly back to their familiar landmarks.

C.It’s very simple that the birds use sense of direction.

17---20     DBCD

       Scientists have found what look like caves on Mars(火星), and say they could be protecting life from the planet’s terrible environment.

       The first caves discovered beyond the Earth appear as seven mysterious black dots on the pictures sent back by NASA’s Mars Odyssey orbiter. Each as large as a football field, they may be openings into natural caves below the Martian surface.

       “If there is life on Mars, there is a good chance you’d find it in caves,” said Jut Wynne,one of the researchers who noticed the features while working on a US Geological Survey Mars Cave Detection Program.

       Jonathan Clarke, a geologist with the Mars Society of Australia, yesterday described the discovery as exciting.

        One photo taken at night by an infrared imager(红外线成像器) showed one hole to be unusually warm, suggesting hot air trapped during the day is flowing out.

        “I said:‘Wow, that’s a cave’” Dr. Clarke said excitedly. “People have been looking for these for a long time; now we have found them.”

         He agreed such caves would be perfect places to hunt for life escaping from the bitterly cold, radiation-soaked(充满辐射的), dry surface.

       “Tiny drops of water could collect inside,” he said. “If there are gases coming out, they could provide energy for a whole range of bacteria. A cave is also a protection from radiation; the surface of Mars is exposed to high levels of space radiation.”

        The caves probably formed when tube-shaped lave flows(管状岩浆流) spread across the planet long ago. The outside of the tubes cooled, forming solid walls, while something hotter inside allowed the remaining have to flow out, forming caves.

64.What does the passage mainly talk about?

A. How the caves were formed on Mars.            

B. How scientists found these caves on Mars.

C. Caves on Mars may be full of hot air or a sign of life.

D. Scientists have completely recognized the surface of Mars.

65.We can learn from the passage that           .

A. water has already been found on Mars           

B. the scientists found all the caves at night

C.it is certain that there is life in these caves

D.the surface of Mars is bitterly cold, radiation-soaked and dry

66.According to the passage, Dr. Clarke was so excited because        .

A.such caves could provide energy for life         

B.they had finally found the caves on Mars

C.such caves would be perfect places to hunt for life

D.scientists had long been looking for these caves

67.Necessary conditions for life on Mars mentioned in the passage may include        .

A.lava and energy                                            B.water and radiation from space

C.gases and lava                                               D.water and protection from radiation

第三部分:阅读理解(共20小题,每题2分,满分40分)

阅读下列短文,从每题所给的四个选项中选出最佳选项。

A

       Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time; if corrected too much, he will stop talking. He notices a thousand times a day the difference between the languages he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people’s. In the same way, children learn to do all the other things they learn to do without being taught-to walk, run, climb, whistle, ride a bicycle compare their own performances with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes and correct them for himself. We do it all for him. We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to. Let him work out, with the help of other children if he wants it, what this word says, what the answer is to that problem, whether this is a good way of saying or doing this or not.

If it is a matter of right answers, as it may be in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time on such routine work? Our job should be to help the child when he tells us that he can’t find the way to get the right answer. Let the children learn what all educated persons must some day learn, how to measure their own understanding, how to know what they know or do not know.

56.According to the passage, the best way for children to learn things is by              .

       A.listening to skilled people’s advice

       A.Give children correct answers.      

       B.Allow children to make mistakes.

       C.Point out children’s mistakes to them.   

       D.Let children mark their own work.

58.The passage suggests that learning to speak and learning to ride a bicycle are    .

       A.different from learning other skills                B.the same as learning skills

       C.more important than other skills                   D.not really important skills

59.The title of this passage could probably the            .

       A.Let Us Teachers Stop Work                         B.Let Us Make Children Learn

       C.Let Children Correct Their Exercises            D.Let Children Learn by Themselves
