1. In the years since the city of London imposed strict air-pollution regulations on local industry, the number of bird species seen in and around London has increased dramatically. Similar air-pollution rules should be imposed in other major cities.
Each of the following is an assumption made in the argument above EXCEPT:
(A) In most major cities, air-pollution problems are caused almost entirely by local industry.
(B) Air-pollution regulations on industry have a significant impact on the quality of the air.
(C) The air-pollution problems of other major cities are basically similar to those once suffered by London.
(D) An increase in the number of bird species in and around a city is desirable.
(E) The increased sightings of bird species in and around London reflect an actual increase in the number of species in the area.
答案选A, 我选E.
我认为a可以作为一个assumption, 因为题中给出regulations on local industry. 将A取非, 如果空气污染并非主要发生在local industry,那么该措施岂不是无效?
2. The burden of maintaining the U.S. highway system falls disproportionately on the trucking industry. Trucks represent only about 10 percent of the vehicles on U.S. roads. Yet road use taxes assessed on trucks amount to almost half the taxes paid for highway upkeep and repair.
Which of the following, if true, would most weaken the argument above?
(A) The trucking industry has enjoyed record after-tax profits in three of the past four years.
(B) Because of their weight, trucks cause over 50 percent of the damage sustained by highway surfaces each year.
(C) Without an economically viable trucking industry, the cost of goods in the United States would rise significantly.
(D) Road use taxes paid by trucking companies have decreased by 3 percent over the past five years.
(E) Due to years of neglect, U.S. highways today are badly in need of major repairs and rebuilding.
答案选b.
我不太理解b的意思, 原以为它要说卡车重,所以缴费也多,可b像在说卡车造成的路面损失的主要原因,不是成了support?

4. In the effort to fire a Civil Service employee, his or her manager may have to spend up to $100,000 of tax money. Since Civil Service employees know how hard it is to fire them, they tend to loaf. This explains in large part why the government is so inefficient.
It can be properly inferred on the basis of the statements above that the author believes which of the following?
I. Too much job security can have a negative influence on workers.
II. More government workers should be fired.
III. Most government workers are Civil Service employees.
答案选I. 我不太理解原题中最后一句话infer的意思, 如果政府没有效率,用给出的理论推断,是否可以说大多数公务员工作不努力, 应该被炒?
5. The U.S. census is not perfect: thousands of Americans probably go uncounted. However, the basic statistical portrait of the nation painted by the census is accurate. Certainly some of the poor go uncounted, particularly the homeless; but some of the rich go uncounted as well, because they are often abroad or traveling between one residence and another.
Which of the following is an assumption on which the argument above depends?
(A) Both the rich and the poor have personal and economic reasons to avoid being counted by the census.
(B) All Americans may reasonably be classified as either poor or rich.
(C) The percentage of poor Americans uncounted by the census is close to the percentage of rich Americans uncounted.
(D) The number of homeless Americans is approximately equal to the number of rich Americans.
(E) The primary purpose of the census is to analyze the economic status of the American population.
答案选c. 为什么b不对.如果b取非, 结论也不能成立啊?
