16. In Swartkans territory, archaeologists discovered charred bone fragments dating back one million years. Analysis of the fragments, which came from a variety of animals, showed that they had been heated to temperatures no higher than those produced in experimental campfires made from branches of white _ stinkwood, the most common tree around Swartkans.
Which of the following, if true, would, together with the information above, provide the best basis for the claim that the charred bone fragments are evidence of the use of fire by early hominids?
(A) The white stinkwood tree is used for building material by the present-day inhabitants of Swartkans. ,
(B) Forest fires can heat wood to a range of temperatures that occur in campfires.
(C) The bone fragments were fitted together by the archaeologists to form the complete skeletons of several animals.
(D) Apart from the Swartkans discovery, there is reliable evidence that early hominids used fire as many as 500,000 years ago.
(E) The bone fragments were found in several distinct layers of limestone that contained primitive cutting tools known to have been used by early hominids.

18. Opponents of laws that require automobile drivers and passengers to wear seat belts argue that in a free society people have the right to take risks as long as the people do not harm others as a result of taking the risks. As a result, they conclude that it should be each person's decision whether or not to wear a seat belt.
Which of the following, if true, most seriously weakens the conclusion drawn above?
(A) Many new cars are built with seat belts that automatically fasten when someone sits in the front seat.
(B) Automobile insurance rates for all automobile owners are higher because of the need to pay for the increased injuries or deaths of people not wearing seat belts.
(C) Passengers in airplanes are required to wear seat belts during takeoffs and landings.
(D) The rate of automobile fatalities in states that do not have mandatory seat-belt laws is greater than the rate of fatalities in states that do have such laws.
(E) In automobile accidents, a greater number of passengers who do not wear seat belts are injured than are passengers who do wear seat belts.
正确答案是B选项，我知道B选项想表达的意思是，由于没有系安全带而导致死亡率上升使得保险费上升，因此系不系安全带并不是人们自己的选择，因为它伤害到了others。但是我想问一下关于B的标书中，有一句the increased injuries or deaths of people not wearing seat belts.这句话应该如何理解？其中的of是理解为人们由于没有系安全带而死亡还是，人们由于没有系安全带的人而死亡？（可能有点绕，希望大家能看明白）
23. With the emergence of biotechnology companies, it was feared that they would impose silence about proprietary results on their in-house researchers and their academic consultants. This constraint, in turn, would slow the development of biological science and engineering.
Which of the following, if true, would tend to weaken most seriously the prediction of scientific secrecy described above?
(A) Biotechnological research funded by industry has reached some conclusions that are of major scientific importance.
(B) When the results of scientific research are kept secret, independent researchers are unable to build on those results.
(C) Since the research priorities of biotechnology companies are not the same as those of academic institutions, the financial support of research by such companies distorts the research agenda.
(D) To enhance the companies' standing in the scientific community, the biotechnology companies encourage employees to publish their results, especially results that are important.
(E) Biotechnology companies devote some of their research resources to problems that are of fundamental scientific importance and that are not expected to produce immediate practical applications.没

我想问一下impose silence是什么意思？这个文章的推理过程是怎样的？不太理解？能解释一下吗？3Q~~
57. Among the more effective kinds of publicity that publishers can get for a new book is to have excerpts of it published in a high-circulation magazine soon before the book is published. The benefits of such excerption include not only a sure increase in sales but also a fee paid by the magazine to the book's publisher.
Which of the following conclusions is best supported by the information above?
(A) The number of people for whom seeing an excerpt of a book in a magazine provides an adequate substitute for reading the whole book is smaller than the number for whom the excerpt stimulates a desire to read the book.
(B) Because the financial advantage of excerpting a new book in a magazine usually accrues to the book's publisher, magazine editors are unwilling to publish excerpts from new books.
(C) In calculating the total number of copies that a book has sold, publishers include sales of copies of magazines that featured an excerpt of the book.
(D) The effectiveness of having excerpts of a book published in a magazine, measured in terms of increased sales of a book, is proportional to the circulation of the magazine in which the excerpts are published.
(E) Books that are suitable for excerpting in high-circulation magazines sell more copies than books that are not suitable for excerpting.

正确答案是A，问题问的是文章的结论支持哪个选项，我觉得最后一句话应该能算的上支持C选项吧？最后一句话的意思，如果我没有理解错误的话，是不是这种好处不仅能使销量增加，而且这些费用也会支付给book’s publisher?错误在哪呢？
总结了一下，自己的问题好像是大部分在阅读文章的时候看不太明白，不知道这和考没考过T有关系吗？总觉得有一些比较地道的表达，我看不明白。。。希望大家有什么好的意见能提高下理解能力的，可以告诉我，谢谢了！~
