课时跟踪练(一) Welcome to the unit & ReadingPre-reading.阅读理解AIf the earths population is in growth at this rate, there will not be enough resources. By the middle of the 21st century, if present trends continue, we will have used up all the oil that drives our cars, for example. Even if scientists develop new ways of feeding the human race, the crowded conditions on the earth will make it necessary for us to look for open space somewhere else. But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however, has recently been suggested by American scientist, Professor Carl Sagan.Sagan believes that before the earths resources are completely exhausted it will be possible to change the atmosphere of Venus and so create a new world almost as large as the earth itself. The difficulty is that Venus is much hotter than the earth and there is only a tiny amount of water there.Sagan proposes that algae organisms (海藻有机体) that can live in extremely hot or cold atmospheres and at the same time produce oxygen, should be bred in condition similar to those on Venus. As soon as this has been done, the algae will be placed in small rockets. Spaceship will then fly to Venus and fire the rockets into the atmosphere. In a fairly short time, the algae will break down the carbon dioxide into oxygen and carbon.When the algae have done their work, the atmosphere will become cooler, but before man can set foot on Venus it will be necessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on but the rain will eventually fall and in a few years something like the earth will be reproduced on Venus.语篇解读：本文是一篇说明文。地球上的资源越来越少，人类的生存即将面临挑战。如何拯救地球上的人类？一些科学家提出了移民金星的建议，同时建议在地球资源耗尽之前在金星上培植一种海藻有机体，让金星产生与地球一样的生存环境。1In the long run, the most difficult problem caused by population growth on the earth will probably be the lack of_.AoilBfoodCresources Dspace解析：选D细节理解题。根据第一段第三句“Even if scientists develop new ways of feeding the human race .look for open space somewhere else.”可知，即使科学家开发出了供养人类的新方式，但是地球上拥挤的状况也使得人们去寻找更开阔的空间。由此可知，人口膨胀最大的问题是空间的问题。故选D项。2Carl Sagan believes that Venus might be a living place because_.Athe days on Venus are long enoughBit might be possible to change its atmosphereCthere is a good supply of water on VenusDits atmosphere is the same as the earths解析：选B细节理解题。根据第二段第一句“. it will be possible to change the atmosphere of Venus and so create a new world almost as large as the earth itself.”可知，金星有可能改变它的大气继而成为适宜人类生存的地方。故选B项。3Algae are plants that can_.Alive in very hot temperatureBlive in very cold temperatureCproduce oxygenDall of the above解析：选D细节理解题。根据第三段第一句可知，海藻有机体可以在极热和极冷的温度下生存，同时还能产生氧气。故选D项。4Man can land on Venus only when_.Ait rains thereBthere is oxygenCthe atmosphere becomes coolerDthe algae have done their work解析：选A推理判断题。在文章最后一段中提到，在人类踏足金星之前需要氧气去制造雨水，然后又提到雨水最后会降落到金星上使得气温下降，这样人类就可以居住了。由此可以推测A项正确。BWelcome to our homepage!Weve teamed up with two travel agencies to give members of our club the chance to win a holiday to the South of France or one to the Maldives.The winner and our three guests will enjoy a sevennight getaway (短假) at the Villa Le Priotlet a centuries old stone villa (别墅) set on the banks of the Dordogne River.

One night, his older son developed a severe stomachache. Thinking it was only some common intestinal (肠的) disorder, neither Al nor his wife took the condition very seriously. But the boy died suddenly that night.Knowing the death could have been avoided if he had only realized the seriousness of the situation, he always felt he was guilty. To make matters worse, his wife left him a short time later, leaving him alone with his sixyearold younger son. The hurt and pain of the two situations were more than Al could stand, and he turned to alcohol for help. In time, Al became an alcoholic.As the alcoholism progressed, Al began to lose everything he possessed his land, house, etc. Finally Al died alone in a small bar. Hearing of Als death, I thought, “What a totally wasted life! What a complete failure！”As time went by, I began to revalue my earlier rough judgment. I knew Als now adult son, Ernie. He is one of the kindest, most caring, and most loving men I have ever known. I saw the love between Ernie and his children, thinking that kindness and love had to come from somewhere.I hadnt heard Ernie talk much about his father. One day, I worked up my courage to ask him what on earth his father had done so that he became such a special person. Ernie said quietly, “As a child until I left home at 18, Al came into my room every night, gave me a kiss and said, Love you, son.”Tears came to my eyes as I realized what a fool I had been to judge Al as a failure. He had not left any material possessions behind. But he had been a kind and loving father, and left behind his best love.语篇解读：本文是一篇记叙文。一个在作者眼中极其失败的人却是一位伟大的父亲，并且培养出了一个极其善良且充满爱心的儿子。8What directly made the author think of Al as a failure?AHis losing everything and his life.BHis older sons death.CHis strong addiction to alcohol.DHis wifes divorcing him.解析：选A细节理解题。根据第三段中的“As the alcoholism progressed, Al began to lose everything .
