PartⅡ Reading Comprehension (30 points)
Directions: There are 3 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center.
Questions 21 to 25 are based on the following passage.
Many people, particularly recent college graduates, dream of owning their own businesses. Although such ventures are often exciting and profitable, the new entrepreneur should thoroughly investigate and plan the situation before plunging in. the first step should be to assemble a board of advisers, including a lawyer, an accountant, and an insurance representative. These individuals can provide valuable information and counsel. Securing the necessary licenses and permits is also a precondition and may require research to determine what is necessary. Most successful small-business owners have considerable experience in the field working for others before they become independent. They also begin with substantial financial backing and a good location. Renting space may be preferable or necessary at the start, but the lease on the building must be examined carefully before it is signed. The new owner should be thoroughly familiar with the market and the competition. A person who wants to buy an existing business can often learn the history of the company and its prospects from the owner’s records. Once the business gets started, accurate and complete records should be kept to monitor the company’s progress and profits.
Financing may be the most difficult step for small-business owners. They may rely
on their own savings or borrow money from a bank or the Small Business Administration. Some suppliers will sell merchandise on credit, and manufacturers may be willing to finance the purchase of equipment. If the new business is a corporation, the owner may choose to sell stock.
Once the new business is started, the Small Business Administration is a good source of advice. Several of its programs are designed to help new owners with the advice and expertise of retired executives. A nearby university or trade association may also help owners locate local sources of help.
New business owners often report that they work long, hard hours but find the experience extremely satisfying. The realization that their efforts will produce actual results in the form of profit, success, and pride can be quite motivating. Those who have worked for others enjoy the opportunity to make decisions and follow projects through to completion. Many report that hard work has never been so enjoyable before. Careful research, investigation, and planning at the outset do not guarantee success, but they provide a good foundation for the new small business and its owner.
21. The main idea of the passage is about _________.
A) the history of the small business
B) tips on how to start your own business
C) how a small business works
D) the best way to build up a profitable business
22. Which of the following advisers is most necessary before you begin?
A) A retired executive.
B) A bank officer.
C) A professor of economics.
D) A lawyer.
23. The article indicates that most successful small-business owners are _______.
A) recent college graduates
B) new entrepreneurs
C) financially secure
D) experienced in the field
24. One advantage of buying an existing business over starting a new one is that ______.
A) it has records readily available
B) it minimizes the competition
C) it is cheaper
D) it already has many customers
25. New business owners may avoid potential problems by ______.
A) hard work
B) selling stock
C) careful planning
D) buying on credit
Questions 26 to 30 are based on the following passage.
Britain almost more than any other country in the world must seriously face the
problem of building upwards, that is to say, of accommodating a considerable proportion of its population in high blocks of flats. It is said that the English man objects to this type of existence, but if the case is such, he does in fact differ from the inhabitants of most countries of the world today. In the past our own blocks of flats have been associated with the lower-income groups and they have lacked the obvious provisions, such as central heating, constant hot water supply, electrically operated lifts from top to bottom, and so on, as well as such details, important notwithstanding (然而), as easy facilities for disposal of dust and rubbish and storage places for baby carriages in the ground floor, playgrounds for children on the top of the buildings, and drying grounds for washing. It is likely that the dispute regarding flats versus (对，对抗) individual houses will continue to rage on for a long time as far as Britain is concerned. And it is unfortunate that there should be hot feelings on both sides whenever this subject is raised. Those who oppose the building of flats base their case primarily on the assumption (设想) that everyone prefers an individual home and on the high cost per unit of accommodation. The latter ignores the higher cost of providing full services to a scattered community and the cost in both money and time of the journeys to work for the suburban resident.
26. We can infer from the passage that _____.
A) English people, like most people in other countries, dislike living in flats
B) people in most countries of the world today are not opposed to living in flats
C) people in Britain are forced to move into high blocks of flats
D) modern flats still fail to provide the necessary facilities for living
27. What is said about blocks of flats built in the past in Britain?
A) They were mostly inhabited by people who did not earn much.
B) They were usually not large enough to accommodate big families.
C) They were sold to people before necessary facilities were installed.
D) They provided playgrounds for children on the top of the buildings.
28. The word "rage" (Line 9) means _____.
A) be ignored
B) develop with great force
C) encourage people greatly
D) be in fashion
29. Some people oppose the building of flats because _____.
A) the living expenses for each individual family are higher
B) it involves higher cost compared with the building of houses
C) they believe people like to live in houses with gardens
D) the disposal of rubbish remains a problem for those living in flats
30. The author mentions that people who live in suburban houses _____.
A) do not have access to easy facilities because they live away from the city
B) have to pay a lot of money to employ people to do service work
C) take longer time to know each other because they are a scattered community
D) have to spend more money and time traveling to work every day
Questions 31 to 35 are based on the following passage
Most people would agree that, although our age exceeds all previous ages in knowledge, there has been no corresponding increase in wisdom. But Agreement ceases as soon as we attempt to define "wisdom" and consider means of promoting it.
There are several factors that contribute to wisdom. Of these I should put first a sense of proportion: the capacity to take account of all the important factors in a problem and to attach to each its due weight. This has become more difficult than it used to be owing to the extent and complexity of the special knowledge required of various kinds of technicians. Suppose, for example, that you are engaged in research in scientific medicine. The work is difficult and is likely to absorb the whole of your mind. You have no time to consider the effect which your discoveries or inventions may have outside the field of medicine. You succeed (let us say) as modern medicine has succeeded, in enormously lowering the infant death-rate, not only in Europe and America, but also in Asia and Africa. This has the entirely unintended result of making the food supply inadequate and lowing the standard of life in the parts of the world that have the greatest populations. To take an even more dramatic example, which is in everybody's mind at the present time; you study the makeup of the atom from a disinterested (无利害关系的) desire for knowledge, and by chance place in the hands of a powerful mad man the means of destroying the human race.
Therefore, with every increase of knowledge and skill, wisdom becomes more necessary, for every such increase augments (增强)our capacity for realizing our purposes, and therefore augments our capacity for evil, if our purpose are unwise.
31. Disagreement arises when people try to decide _____.
A) how much more wisdom we have now than before
B) what wisdom is and how to develop it
C) if there is a great increase of wisdom in our age
D) whether wisdom can be developed or not
32. According to the author, "wisdom" is the ability to _____.
A) carefully consider the bad effects of any kind of research work
B) give each important problem some careful consideration
C) acquire a great deal of complex and special knowledge
D) give suitable consideration to all the possible elements in a problem
33. Lowering the infant death-rate may _____.
A) prove to be helpful everywhere in the world
B) give rise to an increase in population in Europe
C) cause food shortages in Asia and Africa
D) raise the living standard of the people in Africa
34. The author uses the examples in the passage to illustrate his point that _____.
A) it's extremely difficult to consider all the important elements in problem
B) success in medical research has its negative effects
C) scientists may unknowingly cause destruction to the human race
D) it's unwise to be totally absorbed in research in scientific medicine
35. What is the main idea of the passage? _____
A) It is unwise to place the results of scientific research in the hands of a powerful mad man.
B) The more knowledge one has, the wiser one becomes.
C) Any increase of knowledge could lead to disastrous results without the guidance of wisdom.
D) Wisdom increases in proportion to one's age.
