Answer the questions
26、 on each text by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1. 45 Trees are useful to man in three very important ways: they supply him with wood and other products; they give him shade; and they help to prevent droughts and floods. Unfortunately, in many parts of the world, man has no
27、t realized that the third of these service is the most important. In his eagerness to draw quick profit from the trees, he has cut them down is large numbers, only to find that without them he has lost the best friends he had. 2 000 years ago a rich and powerful country cut down its trees to build w
28、arships, with which to gain itself an empire. It gained the empire but, without its trees, its soil became hard and poor. When the empire fell to pieces, the home country found itself faced floods and starvation. Even if a government realizes the importance of adequate supply of trees, it is difficu
29、lt for it to persuade the villager to see this. The villager wants wood to cook his food with; and he can earn money by producing charcoal or selling wood to the townsman. He is usually too lazy or too careless to plant and take care of new trees. So, unless the government has a good control system,
30、 or can educate the people, the forests will slowly disappear. This does not only mean that the villagers sons and grandsons have fewer trees. The results are even more serious: for where there are trees their roots break the soil up allowing the rain to sink in and also bind the soil, thus preventi
31、ng its being washed away easily; but where there are no trees, the rain falls on hard ground and flows away from the surface, causing floods and carrying away with it the rich topsoil , in which crops grow so well. When all the top soil is gone, nothing remains but a useless desert. 46 What is the m
32、ost important function of trees? （ A） Providing fuel. （ B） Offering shade. （ C） Preventing natural disasters. （ D） Providing charcoal. 47 What eventually happened to the rich, powerful country 2 000 years ago? （ A） Its people died of hunger. （ B） It fell to pieces. （ C） It became a giant empire. （ D
33、） It built many ships with wood. 48 It is implied in the passage that the villager _. （ A） wants a plentiful supply of trees （ B） wants fire wood （ C） wants to get money （ D） is not aware of the importance of environmental protection 49 The role of trees is to _. （ A） loose soil （ B） keep soil in po
34、sition （ C） harden soil （ D） Both A and B 50 What does the passage mainly talk about? （ A） The three benefits provided by trees. （ B） Trees and soil conservation. （ C） The various uses of trees. （ D） The different attitudes of the government and the villagers toward trees. 50 Labor force is defined
35、as being the total number of people who are available to work and earn income. This definition includes everyone who is employed or seeking paid employment, so it includes employees and the self-employed. Labor is one of the countrys resources which can be combined with other resources to produce th
36、e 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 populati
37、on 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
38、 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 unadequate numbers of young people entering it to take pl
39、ace 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 increase in births or a falling birth rate. The age distribution of the population has several important influences on the econom
40、y. 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 work force, 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
41、 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
42、to be taxed more heavily. 51 Labor force is composed of _. （ A） people who are available to work and earn income （ B） self-employed people only （ C） only those who are looking for an employment （ D） only the employees 52 The factor which does NOT influence the size of the workforce is _. （ A） the si
43、ze of population （ B） age distribution of the population （ C） national economy （ D） natural increase 53 The conclusion which can be drawn safely from the second paragraph is that _. （ A） a population growth from natural increase leads to a greater proportion of the workforce （ B） a large population
44、does not necessarily mean a higher proportion of workforce （ C） the larger the number of the aged in a population, the higher the proportion of the workforce （ D） if the population has an evenly spread age distribution, the workforce will be lower 54 When a population is said to be aging, （ A） more
45、people are retiring than people entering the workforce _. （ B） the birth rate is growing （ C） there is an oversupply of workforce （ D） young people outnumber old people 55 The population which is top-heavy with older people poses a problem to _. （ A） the government （ B） the economy （ C） the workforc
46、e （ D） all of the above 55 Finishing teachers evaluations need maturity and objectivity. Every semester we have the opportunity to evaluate our instructors. We are supposed to judge their lectures, interest in students problems, methods of assigning work, and general ability to conduct a class. Then
47、, when the instructor has left the room, we must write our evaluations on the forms provided. We are not sup-posed to exchange view or discuss our responses. After everyone has completed the forms, one student collects and tallies the responses and then puts them in an envelope and makes them sealed
48、. It is very difficult to evaluate another persons performance objectively. For example, Senta recently wrote irresponsible remarks about her instructor because she was falling to pass the course. Her friend Sam wrote a marvelous description of the same instructor because he received an A in the cou
49、rse. Both Senta and Sam were not fairly evaluating the instructor. They were affected by the grades they were earning and were biased in their judgments. Another irresponsible form of evaluation occurred when James rated his instructor excellent because the instructor is “easy“. He gives few tests and only assigns one paper during the entire term. His lectures are often full of jokes and endles
