BWhen I was a boy, I belonged to the Boy Scouts(童子军), so I used to go camping every summer, and once something happened which I have never been able to explain.We were camping in a place above a river. After arriving, we all rushed down to the river had a swim. Standing by the river, we noticed that it was surrounded(环绕)by cliffs (悬崖). If someone wanted to reach the river at this point, he had to walk past our camp.Several days later, the scoutmaster had to he away for a day. That afternoon, we had supper early. We were sitting round the fire, eating and talking, when a man walked past and went down towards the river. We all felt that this man looked very strange, but, because each of us was afraid of looking very stupid, no one said anything.We ate rather slowly, taking as long as possible. After finishing, we collected our plates together so that we could take them to the river where we always washed them. But no one moved towards the river- we stood looking at each other ashamed. Then all shouting at once, we began talking about the man who had walked past us. We agreed how strange he looked and we wondered what he could be doing by the river. We knew that he could only return by passing through our camp.An hour passed. Then one of the boys suggested we should creep(悄悄移动)down by the river so that we could see what the man was doing. Moving very slowly and keeping in the shadow, we crept down towards the bank.One boy climbed a tree so that he could see everything clearly. He called to us that there was no one there, so we ran down to the bank, looking every-where carefully. We could not understand where the man had gone.When it got dark, we went back to our camp feeling bewildered. We told the scoutmaster what had happened in the evening. Smiling, he doubted that we had seen the man, but finally suggested we go and look again. We did, but there was no one there.Many years have passed, but I still remember it as if it were yesterday. What did we see? I do not know.55.The writer in the text mainly tells us _________.A.the story of his childhoodB.a strange camping experienceC.about a stranger by the riverD.about a good place for camping.56.Why did the boys eat their supper slowly?A.They wanted to delay going to the river bank.B.They were waiting for their scoutmaster.C.They had a supper earlier than usual.D.They were taking while eating.57.The word“bewildered”in the text probably means _________.A.ashamedB.nervousC.unable to understandD.eager to know something58.When he heard what had happened, the scoutmaster __________.A.realized who the man wasB.started to worry about the manC.went back to look for the canD.felt it hard to believe the boys59.The writer still remembers the event because________.A.the boys acted foolishlyB.the camping place is beautifulC.there has been no explanation for the eventD.he particularly enjoyed his camping that summer.第三部分：阅读理解（共20小题；每小题2分, 满分40分）阅读下列短文, 从每题所给的A、B、C、D四个选项中, 选出最佳选项。

BIf you dream of going someplace warm to escape the cold winter weather, a trip to a recently discovered planet would certainly warm you right up. The planet, named OGLE-TR-56b, has temperatures of more than 3, 000°F. “This is the hottest planet we know about,” says Dr. Dimitar Sasselov, a scientist who led the discovery team. “It is hot enough to have an iron fog and to rain hot iron droplets(细沫).”The new planet is 30 times farther away than any planet discovered by scientists before. It isin the Milky Way（银河）but it is not in our solar（太阳的）system. The new planet moves around a star much like our sun, however. Scientists discovered the planet by using a new planet-searching method, called “transit technique.” They were able to catch sight of the planet when it moved in front of its star, causing the star’s light to dim(变暗). Scientists compare the m ethod to discovering the shadow of a bee flying in front of a searchlight 200 miles away. “We believe the door has been opened wide to go and discover planets like Earth,” says Sasselov.58. We can infer from the passage that ________.A. there is iron on the new planetB. we could go to the new planet in winterC. the star could block our view of the new planetD. scientists are studying the weather on the new planet59. The “transit technique” can _________.A. help dim the light of a starB. help scientists with a searchlightC. help discover a bee on a planetD. help find a planet moving before its star60. Which is the best title for the passage?A. New Planet-searching Technique.B. New Distant Discovery.C. Space Searching.D. Dream Planet.第三部分：阅读理解（共20小题；每小题2分, 满分40分）阅读下列短文, 从每题所给的A、B、C、D四个选项中, 选出最佳选项。
