以下是引用chenmoon在2003-10-4 22:57:00的发言: 这个being在这里是干什么的?
Sorry, 我想我是说错了,但我查了半天语法书,也不知为什么,但我找到了下列的类似的例句。 期待高手给出理论解释,感谢! 27. The author’s argument regarding the resistance of Africanized bees to Varroa jacobsoni would be most weakened if which of the following were true? (A) The bees in Brazil were resistant before being Africanized. (B) The number of bee colonies in North American increased dramatically whereas the number in Brazil remained unchanged. (C) Mites found in European bees reproduce at a faster rate than mites of identical species found in the bees in Brazil. (D) Africanized bees retain many of the characteristics of European bees. (E) Bee colonies in Europe continue to produce greater quantities of honey than do those in Brazil.
Advocates of the theory, however, point out that other types of carbon exist in the mantle: unoxidized carbon must exist there, because diamonds are formed within the mantle before being brought to the surface by eruptive processes.
8. Dear Applicant: Thank you for your application. Unfortunately, we are unable to offer you a position in our local government office for the summer. As you know, funding for summer jobs is limited, and it is impossible for us to offer jobs to all those who want them. Consequently, we are forced to reject many highly qualified applicants. Which of the following can be inferred from the letter? (A) The number of applicants for summer jobs in the government office exceeded the number of summer jobs available. (B) The applicant who received the letter was considered highly qualified. (C) Very little funding was available for summer jobs in the government office. (D) The application of the person who received the letter was considered carefully before being rejected. (E) Most of those who applied for summer jobs were considered qualified for the available positions.
7. There is no reason why the work of scientists has to be officially confirmed before being published. There is a system in place for the confirmation or disconfirmation of scientific finding, namely, the replication of results by other scientists. Poor scientific work on the part of any one scientist, which can include anything from careless reporting practices to fraud, is not harmful. It will be exposed and rendered harmless when other scientists conduct the experiments and obtain disconfirmatory results. Which one of the following, if true, would weaken the argument? (A) Scientific experiments can go unchallenged for many years before they are replicated. (B) Most scientists work in universities, where their work is submitted to peer review before publication. (C) Most scientists are under pressure to make their work accessible to the scrutiny of replication. (D) In scientific experiments, careless reporting is more common than fraud. (E) Most scientists work as part of a team rather than alone.
10. Which one of the following, if true, most strengthens the argument? (A) The public library was located between Glenwood and Redville before being moved to its current location in central Redville. (B) The area covered by central Glenwood is approximately the same size as that covered by central Redville. (C) The building that is available in Glenwood is smaller than an alternative building that is available in Redville. (D) Many of the people who use the public library do not live in either Glenwood or Redville. (E) The distance that people currently walk to get to the library is farther than what is generally considered walking distance.
15. Municipal officials originally estimated that it would be six months before municipal road crews could complete repaving a stretch of road. The officials presumed that private contractors could not finish any sooner. However, when the job was assigned to a private contractor, it was completed in just 28 days. Which one of the following, if true, does most to resolve the discrepancy between the time estimated for completion of the repaving job and the actual time taken by the private contractor? (A) Road repaving work can only be done in the summer months of June, July and August. (B) The labor union contract for road crews employed by both municipal agencies and private contractors stipulates that employees can work only eight hours a day, five day a week, before being paid overtime. (C) Many road-crew workers for private contractors have previously worked for municipal road crews and vice versa. (D) Private contractors typically assign 25 workers to each road-repaving job site whereas the number assigned to municipal road crews is usually 30. (E) Municipal agencies must conduct a lengthy bidding process to procure supplies after repaving work is ordered and before they can actually start work, whereas private contractors can obtain supplies readily as needed.
Advances in photocopying technology allow criminals with no printing expertise to counterfeit paper currency. One standard anticounterfeiting technique, microprinting, prints paper currency with tiny designs that cannot be photocopied distinctly. Although counterfeits of microprinted currency can be detected easily by experts, such counterfeits often circulate widely before being detected. An alternative, though more costly, printing technique would print currency with a special ink. Currency printed with the ink would change color depending in how ordinary light strikes it, whereas photocopied counterfeits of such currency would not. Because this technique would allow anyone to detect photocopied counterfeit currency easily, it should be adopted instead of microprinting, despite the expense.
