It was still too early for me to have my e veningmeal, so I walked along the seafront (滨海马路) for about an hour until I began to feel hungry.By that time I was not far from a favorite restaurant of mine, where I often went to eat two or three times a week. I knew the owner well and frequently complimented (赞美, 恭维) him on his excellent cooking.I went into the restaurant, which was already crowded, and ordered my meal. While I waswaiting for the soup to arrive, I looked around to see if I knew anyone in the restaurant. It was then that I noticed that a man sitting at a corner table near the door kept glancing in my direction, as if he knew me, I certainly did not know him, for I never forgot a face. The man hada newspaper open in front of him, which he was pretending to read, though all the while I couldsee that he was keeping an eye on me. When the waiter brought my soup, the man was clearly puzzled by the familiar way in which the waiter and I addressed each other. He became even more puzzled as time went on and it grew more and more obvious that I was well known in the restaurant. Eventually he got up and went into the kitchen. After a few minutes he came out again, paid his bill and left without another glance in my direction.When I had finished and was about to pay my bill, I called the owner of the restaurant over and asked him what the man had wanted. The owner was a little embarrassed by my question and at first did not want to tell me. I insisted. “Well,” he said, “that man was a detective.” “Really?” I said, considerably surprised. “He f ollowed you here because he thought you were a man he was looking for,” the owner of the restaurant said. “When he came into the kitchen, he showed me a photograph of the wanted man. He certainly looked like you! Of course, since we know you here, I was ab le to convince him that he had made a mistake.” “It’s lucky I came to a restaurant where I am known,” I said, “otherwise I might have been arrested!”1.When the author got to his favorite restaurant, it was _____D______ .A) already nine o’clockB) eight o’clock on the dotC) about two minutes past eightD) slightly later than eight o’clock2.The man sitting at the corner table near the door kept glancing in the direction of the author because he was ________D__________ .A) interested in the personality of the authorB) making a study of the authorC) looking up and down the authorD) keeping a lookout over the author3.The author was followed by the detective probably because he _____A______ .A) took after a suspectB) was similar to a criminal in personalityC) was an accompliceD) looked like a murdererB4.The detective had a newspaper open in front of him in order to _____B_______ .A) read it in detailB) cover up what he was really doing thereC) have it recheckedD) wait for his food5.According to the text, if the author had been a stranger in the restaurant, he would have been ___________C_________.A) taken to courtB) followedC) capturedD) sentenced to a few years’ imprisonment2．A very important world problem is the rapidly increasing pressure of population on land and on land resources.It is not so much the actual population of the world but its rate of increase which is important. It works out to be about 1.6 per cent per annum net increase. In terms of numbers this means something like forty to fifty-five million additional people every year. Canada has a population of twenty million--rather less than six months' climb in world population. Take Australia. There are ten million people in Australia. So, it takes the world less than three months to add to itself a population which peoples that vast country. Let us take our own crowded country--England and Wales: forty-five to fifty million people--just about a year's supply.By this time tomorrow, and every day, there will be added to the earth about 120,000 extra people, just about the population of the city of York.This enormous increase of population will create immense problems. By A.D. 2000, unless something desperate happens, there will be as many as 7,000,000,000 people on the surface of this earth! So this is a problem which you are going to see in your lifetime.Why is this enormous increase in population taking place? It is really due to the spread of the knowledge and the practice of what is coming to be called Death Control. Death Control is something rather different from Birth Control. Death Control recognizes the work of the doctors and the nurses and the hospitals and the health services in keeping alive people who, a few years ago, would have died of some of the incredibly serious killing diseases, as they used to be. Squalid conditions, which we can remedy by an improved standard of living, caused a lot of disease and dirt. Medical examinations at school catch diseases early and ensure healthier school children. Scientists are at work stamping our malaria and other more deadly diseases. If you are seriously ill there is an ambulance to take you to a modern hospital. Medical care helps to keep people alive longer. We used to think seventy was a good age; now eighty, ninety, it may be, are coming to be recognized as a normal age for human beings. People are living longer because of this Death Control, and fewer children are dying, so the population of the world is shooting up.Imagine the position if you and I and everyone else living on earth shared the surface between us. How much should we have each? It would be just over twelve acres--the sort of size of a small holding. But not all that is useful land which is going to produce food. We can cut out one-fifth of it, for example, as being too cold. That is land which is covered with ice and snow--Antarctica and Greenland and the great frozen areas of northern Canada. Then we can cut out another fifth as being too dry--the great deserts of the world like the Sahara and the heart of Australia and other areas where there is no known water supply to feed crops and so to produce food. Then we can cut out another fifth as being too mountainous or with too great an elevation above sea level. Then we can cut out another tenth as land which has insufficient soil, probably just rock at the surface. Now, out of the twelve acres only about four are left as suitable for producing food.. But not all that is used. It includes land with enough soil and enough rainfall or water, and enough heat which, at present, we are not using, such as, for example, the great Amazon forests and the Congo forest and the grasslands of Africa. How much are we actually using? Only a little over one acre is what is required to support one human being on an average at the present time.6. The world's population is increasing because _____B__.。
