【正文】 the world to increase its population from 1 billion to 4 billion. A. 100 years B. 175 years C. 1975 years D. over two million years 44. Which of the following statements is NOT true?A. World population is increasing at a rate of 150 per minute. B. Lower death rate also contributes to world population growth. C. The population of Columbia has been doubling every year for 21 years. D. The United States is usually doubling its population on about every 87 years. 45. When a population doubles, the country involved needs twice as much of everything including __. A. hospitals and medicines B. schools and students C. food and manpower resources D. all of the above Questions 46 to 50 based on the following passage:Passage Two Women are on the whole more verbal than men. They are good at 1anguage and verbal reasoning. while men tend to be skilled at tasks demanding visualspatial(視空)abilities. In fact, along with aggression these are the most monly accepted difference between these sexes. Words are tools for municating with other people especially information about people. They are mainly social tools. Visual and spatial abilities are good for imagining and manipulating objects and for municating information about them. Are these talents programmed into the brain? In some of the newest and most controversial research in neurophysiology(神經(jīng)生理學(xué)), it has been suggested that when it es to the brain males are specialists while women are generalists. But one knows that, if anything this means in terms of the abilities of the two sexes. Engineering is both Visual and spatial and it’s true that there are relatively few women engineers. But women bee just as skilled as men at shooting a rifle or driving a car task that involve visualspatial skills. They also do equally well at programming a puter, which is neither visual nor spatial. Women do, however, seem less likely to fall in love with the objects themselves. We all know men for whom machines seem to be extensions of their identity. （82）A woman is more likely to see her car, rifle or puter as a useful tool but not in itself fascinating. 46. According to the passage, women are usually good at_____. A. body language B. logical reasoning C. tasks demanding for the use of words D. both A and B 47. The word accepted” in the last sentence of the first paragraph, roughly means_____. A. believed B. assumed C. received D. reconciled 48. In the author’s opinion, visual and spatial abilities are good for______. A. achieving one’s objects. B. mind and body. C. programming talents into the brain. D. imagination and munication. 49. All the following tasks involve visualspatial abilities EXCEPT____. A. imagining and handling objects. B. providing a puter with a set of instructions C. shooting a gun and driving an automobile D. planning and making things as an engineer does 50. Why do women seem less likely to fall in love with the objects themselves? A. Because they have no visualspatial skills. B. Because they are only good at 1anguage and verbal reasoning. C. Because they are less likely to see their charming or interesting aspects. D. Because they rarely use machines such as cars, rifles, puters, etc. Questions 51 to 55 are based on the following passage:Passage Three The US. government has recently helped people learn more about the dangers of earthquakes by publishing a map. This map shows the chances of an earthquake in each part of the country. （83）The areas of the map where earthquakes are most likely to occur are called earthquake “belt”. The government is, spending a great deal money and is working hard to help discover the answer to these two questions: l. Can we predict earthquake? 2. Can we control earthquakes? To answer the first question, scientists are looking very closely at the most active fault(斷層)systems in the country such as the San Andreas fault in California, a fault is break between two sections of the earth’s surface. These breaks between sections are the place where earthquake occurs. Scientists look at the faults for changes that might show that an earthquake was about to occurs. But it will probably be many years before we can predict earthquakes accurately. And the control of earthquakes is even farther away. Nevertheless, there have been some interesting developments in the field of controlling earthquakes. The most interesting development concerns the Rocky Mountain Arsenal earthquakes. Here water was put into a layer of rocks 4000 meters below surface of the ground. Shortly after this injection of water, there were a small number of earthquakes. Scientists have decided that the water which was injected into rocks works like oil on each other. When the water“oiled”the fault, the fault became slippery and the energy of an earthquake was released. Scientists are still experimenting at the site of these earthquakes. They have realized that there is a connection between injection of the water and the earthquake activity. They have suggested that might be possible to use this knowledge to prevent very big destructive earthquakes, that is, scientists could inject some kind of fluid like water into faults and change one big earthquake into a number of small, harmless earthquakes. 51. Earthquake belts are . A. maps that show where earthquakes are likely to occur B. zones with a high probability of earthquakes C. breaks between two sections of the earth’s surface D. the two layers of earth along a fault 52. The San Andreas’ fault is . A. an active fault system B. a place where earthquakes have been predicted accurately C. a place w
