4、Because she has a great need for ------- , she loathes the public appearances demanded of her as a leading literary figure.

　　(A) luxury

　　(B) privacy

　　(C) reward

　　(D) devotion

　　(E) distraction

答案：B

5、When, in 1864, a factory established by Alfred Nobel to manufacture nitroglycerin blew up, the scientist discovered that the explosive was as ------- as it was powerful, ------- to detonate without warning.

　　(A) dormant . . ready

　　(B) fickle . . unlikely

　　(C) volatile . . liable

　　(D) unprecedented . . intended

　　(E) inactive . . designed

答案：C

解析：Choice (C) is correct. It makes sense to say that when his factory exploded, Nobel discovered how “volatile,” or unpredictable, nitroglycerin could be; in fact, it was “liable” to, or prone to, detonate unexpectedly.

6、To some scholars of medieval Britain, the legendary King Arthur is a genuine historical figure, while to others he and his Round Table are nothing more than ------- of myth and romance.

　　(A) harbingers

　　(B) trifles

　　(C) spoilers

　　(D) figments

　　(E) inventors

答案：D

解析：The sentence focuses on the contrast between what two groups of scholars think about King Arthur. Some scholars think King Arthur is a real “historical figure”—a real person—while others think he is not. Those who think King Arthur and his Round Table are not real would probably call them “figments,” or things that are made up.
