Answer the questions on each text by choosing[A], [B], [C]or[D]. {{/I}} Even plants can run a fever, especially when they' re under attack by insects or disease. But unlike humans, plants can have their temperature taken from 3 000 feet away—straight up. A decade ago, adapting the infrared(红外线)scanning technology developed for military purposes and other satelities, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones were under stress. The goal was to let farmers precisely target pesticide(杀虫剂)spraying rather than rain poison on a whole field, which invariably includes plants that don't have pest(害虫)problems. Even better, Paley' s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3 000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running "fevers". Farmers could then spot-spray ,using 50 to 70 percent less pesticide than they otherwise would. The bad news is that Paley' s company closed down in 1984, after only three years. Farmers resisted the new technology and long-term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt that the technology works. "This technique can be used on 75 percent of agricultural land in the United States, "says George Oerther of Texas A & M. Ray Jackson, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago.

单选题{{B}}Text 3{{/B}} Labor force is defined as being the total number of people who are available to work and earn in- come. This definition includes everyone who is employed or seeking paid employment, so it includes employees and the self-employed: Labor is one of the Country's resources which can be combined with other resources to produce the goods and services required by the community. Though the size of the workforce relies greatly on the size of the total population, there are several other aspects which also affect it. The age distribution of the total population has a very marked effect on the available workforce. If the population has a high proportion of very young people or of those too old to work, then the available workforce would be lower than if there were an evenly spread age distribution. If the population grows rapidly from natural increase, i.e. the number of births greatly exceeds the number of deaths, then as a total population increases the proportion in the workforce declines. Sometimes a population is described as aging, which means that the birth rate is either falling or growing very slowly, and as people retire from the workforce there are inadequate numbers of young people entering it to take place of those who are leaving it. The population is top-heavy with older people. So the percentage of the population in the workforce declines when there is either a rapid in- crease in births or a falling birth rate. The age distribution of the population has several important influences on the economy. If the population is aging and there is an increase in the number of people retiring without a corresponding increase in the number entering the workforce, this raises the problem of the ability of the economy to provide a reasonable level of social services to the retired group. If the aged are to be cared for in special homes or hotels, finance must be available for that purpose. If the size of the workforce is small relative to the total population, then the government tax receipts are relatively low and either the government has less money available to it or the workforce members have to be taxed more heavily.

单选题As my train was not due to leave for another hour, I had plenty of time to spare. After buying some magazines to read on the journey, I made my way to the luggage office to collect the heavy suitcase. I had left there three days before. There were only a few people waiting, and I took out my wallet to find the receipt for my case. The receipt did not seem to be where I had left it. I emptied the contents of the wallet, and railway tickets, money, scraps of paper, and photographs tumbled out of it; but no matter how hard I searched, the receipt was nowhere to be found. When my turn came, I explained the situation sorrowfully to the assistant. The man looked at me suspiciously as if to say that he had heard this type of story many times and asked me to describe the case. I told him that it was an old, brown-looking object not different from the many cases I could see on the shelves. The assistant then gave me a form and told me to make a list of the chief contents of the case. I were correct, he said, I could take the case away. I tried to remember all the articles I had hurriedly packed and wrote them down as they came to me. After I had done this, I went to look among the shelves. There were hundreds of cases there and for one dreadful moment, it occurred to me that if someone had picked the receipt up, he could have easily claimed the case already. This had not happened fortunately. For after a time, I found the case lying on its side high up in a comer. After examining the articles inside, the assistant was soon satisfied that it was mine and told me I could take the case away. Again I took out my wallet: this time to pay. I pulled out a ten shilling note and the "lost" receipt slipped out with it. I could not help blushing and glanced up at the assistant. He was nodding his head knowingly, as if to say that he had often seen this happen before too !

单选题Children in the United States are exposed to many influences other than that of their families. Television is the most significant of these influences, because the habit of watching television usually begins before children start attending school. And, by the time that the average child finishes high school, he or she will have spent 18,000 hours in front of a television set as opposed to 12,000 hours in a classroom. Parents are concerned about these figures. They are also concerned about the lack of quality in television programs for children. The degree of violence in many of these shows also worries them. Even if it is unreal--a cartoon cat beating up a cartoon mouse with a baseball bat--this violence may have a negative effect on the young minds exposed to it. Studies indicate that, when children are exposed to violence, they may become aggressive or insecure. Parents are also concerned about the commercials that their children see on television. Many parents would like to see fewer commercials during programs for children. And some parents feel that these shows should not have any commercials at all because young minds are not mature enough to deal with the claims made by advertisers. Educational television has no commercials and has programs for children that many parents approve of. The most famous of these is "Sesame Street", which tries to give preschool children a head start in learning the alphabet and numbers. It also tries to teach children useful things about the world in which they live. Even though most parents and educators give "Sesame Street" and shows like it high marks for quality, some critics argue that all television, whether educational or not, is harmful to children. These critics feel that the habit of watching hours of television every day turns children into bored and passive consumers of their world rather than encouraging them to become active explorers of it. We still do not know enough about the effects of watching television to be able to say whether or not it is good for children. Until we do, perhaps it would be wise to put a warning on television sets such as the one on cigarette packages: "Caution: Watching Too Much Television May Be Harmful to Your Child's Developing Mind./

单选题{{B}}{{I}}Questions 11～13 are based on the following dialogue on Thanksgiving in the United States.{{/I}}{{/B}}

单选题The idea of a fish being able to generate electricity strong enough to light lamp bulbs--or even to run a small electricmotor-is almost unbelievable, but several kinds of fish are able to do this. Even more strangely, this curious power has been acquired in different ways by fish belonging to very different families. Perhaps the best known are the electric rays, or torpedoes (电鳐), of which several kinds live in warm seas. They possess on each side of the head, behind the eyes, a large organ consisting of a number of hexagonal shaped cells rather like a honeycomb. The cells are filled with a jelly-like substance, and contain a series of flat electric plates. One side, the negative side, of each plate, is supplied with very fine nerves, connected with a main nerve coming from a special part of the brain. Current passes from the upper, positive side of the organ downwards to the negative, lower side. Generally it is necessary to touch the fish in two places, completing the circuit, in order to receive a shock. The strength of this shock depends on the size of the fish, but newly born ones only about 5 centimetres across can be made to light the bulb of a pocket flashlight for a few moments, while a fully grown torpedo gives a shock capable of knocking a man down, and, if suitable wires are connected, will operate a small electric motor for several minutes. Another famous example is the electric eel. This fish gives an even more powerful shock. The system is different from that of the torpedo in that the electric plates run longitudinally (纵向) and are supplied with nerves from the spinal (脊骨) cord. Consequently, the current passes along the fish from head to tail. The electric organs of these fish are really altered muscles and like all muscles are apt (likely) to tire, so they are not able to produce electricity for very long. The power of producing electricity may serve these fish both for defence and attack.
