1、陕西专升本英语（阅读）模拟试卷 4 及答案与解析0 Population tends to grow at an exponential(指数的 )rate. This means that they progressively double. As an example of this type of growth rate, take one penny and double every day for one month. After the first week, you would have only 64 cents, but after the fourth week you w
2、ould have over a million dollars.This helps explain why the population has come on “all of a sudden“. It took from the beginning of human life to the year 1830 for the population of the earth to reach one billion. That repents(缓慢进行)a time span of at least two million years. Then it took from 1830 to
3、 1930 for world population to reach 2 billion. The next billion was added by 1960, only thirty years, and in 1975 world population reached 4 billion, which is another billion people in only fifteen years.World population is increasing at a rate of 9000 per hour, 220000 per day, and 80 million per ye
4、ar. This is not only due to higher birth rate, but to lower death rate as well. The number of births has not declined at the same rate as the number of deaths. Some countries, such as Columbia, Thailand, Morocco, Costa Rica, and the Philippines, are doubling their population about every twenty - one
5、 years, with a growth rate of 3. 3% a year or more. The United States is doubling its population about very eighty - seven years, with a rate of 0. 8% per year. Every time a population doubles, the country involved needs twice as much of everything, including hospitals, schools, resources, food and
6、medicines to care for its people. It is easy to see that this is very difficult to achieve for the more rapidly growing countries.1 This passage chiefly discusses_.（A）the growth of world population（B） one type of the exponential rate（C） the population problem of more rapidly growing countries（D）the
7、possible ways of dealing with the rapid population growth2 According to the passage, what helps to explain why the population problem has come on “ all of a sudden“ ?_.（A）The penny that doubles itself every day for one month（B） The time span of at least two million years in human history（C） An illus
8、tration of the exponent growth rate given by the author（D）The large amount of money you would luckily make after the fourth week3 It took_for the world to increases its population from 1 billion to 4 billion.（A）100 years（B） 145 years（C） 1975 years（D）over two million years4 Which of the following sta

They are good at language and verbal reasoning, while men
11、 tend to be skilled at tasks demanding visual - spatial(视空)abilities. In fact, along with aggression, these are the most commonly accepted difference between these sexes.Words are tools for communicating with other people, especially information about people. They are mainly social tools. Visual and
12、 spatial abilities are good for imagining and manipulating objects and for communicating information about them. Are these talents programmed into the brain? In some of the newest and most controversial research in neurophysiology(神经生理学 ), it has been suggested that when it comes to the brain, males
13、 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 its true that there are relatively few women engineers. But women become just as skilled as men at shooting a rifle or driv
14、ing a car, task that involve visual - spatial skills. They also do equally well at programming a computer, 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.
15、A woman is more likely to see her car, rifle, or computer as a useful tool but not in itself fascinating.6 According to the massage, women are usually good at_.（A）body language（B） logical reasoning（C） tasks demanding for the use of words（D）both A and B7 The word “accepted“ in the last sentence of th

18、hey have no visual - spatial skills（B） Because they are only good at language 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, computers, etc10 The U. S. government has recently helped people le
19、arn more about the dangers of earthquakes by publishing a map. This map shows the chances of an earthquake in each part of the country. 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
20、help discover the answer to these two questions:(1)Can we predict earthquakes?(2)Can we control earthquakes?To answer the first question, scientists are looking very closely at the most active fault(断层)systems in the country, such as the San Andreas fault in California. A fault is break between two
21、sections of the earths 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 occur. But it will probably be many years before we can predict earthquakes accurately. And the control of ea
22、rthquakes is even farther awayNevertheless, 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. Short
23、ly after this injection of water, there was 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 axe stil
24、l 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
25、some kind of fluid like water into faults and change the big earthquake into a number of small, harmless earthquakes.11 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 earths surface（D
26、）the two layers of earth along a fault12 The San Andreas fault is_.（A）an active fault system（B） a place where earthquakes have been predicted accurately（C） a place where earthquake have been controlled（D）the location of the Rocky Mountain13 What did scientists learn about earthquakes at the Rocky Mo

View
30、ed biologically, the modern footballer is in reality a member of a hunting group. His killing weapon has turned into a harmless football and his prey into a goalmouth. If his aim is accurate and he scores a goal, he enjoys the hunters triumph of killing his prey.To understand how this transformation
31、 has taken place we must briefly look back at our forefathers. They spent over a million years evolving(进化)as cooperative hunters. Their very survival depended on success in the hunting field. Under this pressure their whole way of life, even their bodies, became greatly changed. They became chasers
32、, runners, jumpers, aimers, throwers and prey killers. They cooperated as skillful male group attack.Then about ten thousand years ago, after this immensely long period of hunting the food, they became farmers. Their improved intelligence, so vital to their old hunting life, was put to a new use - t
33、hat of controlling and domesticating(驯养)their prey. The hunt became suddenly out of date. The food was there on the farms, awaiting their needs. The risks and uncertainties of the hunt were no longer essential for survival.The skills and thirst for hunting remained, however, and demanded new outlets
34、. Hunting for sport replaced hunting for necessity. This new activity involved all the original hunting sequences(后果), but the aim of the operation was no longer to avoid starvation. Instead the sportsmen set off to test their skill against prey that was no longer essential to their survival. To be
35、sure, the kill may have been eaten, but there were other purposes, much simpler of obtaining a meaty meal.16 What is the main idea of the passage?_.（A）Hunting is very important in human civilization（B） Sporting activities satisfy the desire of modern society（C） Its hunting that provides human beings
36、 with food（D）The importance of sporting activities in modern society17 According to the author, sporting activities_.（A）are essential to the survival（B） have actually developed from hunting（C） evolve as biological development（D）are football games18 For over a million years, our forefathers were basi
