1. Clearly refuting skeptics, researchers have ________ not only that gravitational radiation exists but that it also does exactly what theory ________ it should do.
(A) doubted.. warranted
(B) estimated.. accepted
(C) demonstrated.. predicted
(D) assumed.. deduced
(E) supposed.. asserted
解析：clearly refuting skeptics 是researchers 发出的动作，所以后面对于这个gravitational radiation的存在表示肯定，不仅而且还要求有递进关系，不仅存在，理论还能很好的说明它。所以选择C选项。
注意warrant这个单词表示officially affirm or guarantee, 表示保证的意思;也可以表示justify or necessitate (a course of action),表示的是使.....显得必要。
单词gravitation表示引力，来自于动词gravitate, 表示倾向于的意思。 例如：My husband is vegetarian, but the children aren't, so they can have anything they want in moderation, though my eldest daughter gravitates towards vegetarianism.
答案：C
2. Sponsors of the bill were ________ because there was no opposition to it within the legislature until after the measure had been signed into law.
(A) unreliable
(B) well-intentioned
(C) persistent
(D) relieved
(E) detained
解析：这里面一定要区分A until B，和not A until B。A until B，说明A在B之前发生。not A until B 说明B在A之前发生，切记这个顺序。
因此这句话说在这个measure写入法律之前没有反对，就说明这个measure成功的写入了法律。那么支持这个measure(bill也表示法案)的人就应该是一个正向的词汇，所以选择D选项，表示释怀。
这道题目要跟section 13 -2 进行横向比较，彻底掌握until的用法。
答案：D
3. The paradoxical aspect of the myths about Demeter, when we consider the predominant image of her as a tranquil and serene goddess, is her ________ search for her daughter.
(A) extended
(B) agitated
(C) comprehensive
(D) motiveless
(E) heartless
解析：这道题目是简单的paradoxical找反义的题目，选择与tranquil和serene相反的单词，于是选择B选项，表示焦虑的。
表示焦虑的单词
agitated = discomposed, disturbed, perturbed, unglued, unhinged, upset,
考试中与焦虑相反的一面还可以说镇定，表示一个人很calm的单词，还可以说：
composed = collected, peaceful, placid, undisturbed, unperturbed, coolheaded.
答案：B
4. Yellow fever, the disease that killed 4,000 Philadelphians in 1793, and so ________ Memphis, Tennessee, that the city lost its charter, has reappeared after nearly two decades in ________ in the Western Hemisphere.
(A) terrorized.. contention
(B) ravaged.. secret
(C) disabled.. quarantine
(D) corrupted.. quiescence
(E) decimated.. abeyance
解析：第二个空格应该是，只有在没有之后才能又重复出现，因此DE合适。第一个空格前面有so，说明第一个空格的动词在前面出现过。因此选一个kill的同义词，因此选择decimate。
decimate - kill, destroy, or remove a large proportion of;
这道题目里面的单词都比较重要。
ravage - cause severe and extensive damage to
quiescence - in a state or period of inactivity or dormancy.
答案：E
5. Although ________ , almost self-effacing in his private life, he displays in his plays and essays a strong ________ publicity and controversy.
(A) conventional.. interest in
(B) monotonous.. reliance on
(C) shy.. aversion toward
(D) retiring.. penchant for
(E) evasive.. impatience with
解析：第一个空格填入一个self-effacing较弱的词汇，而前后需要有矛盾，所以前后应该形成相反，前面说的是不好意思，后面就应该说喜欢暴露在公众场合，符合选项的只有D选项了。
penchant 表示倾向、喜好，之前我们总结过一组倾向喜好的词汇，自己复习一下吧。
shy, retiring, evasive 都可以理解为同义词。注意retiring并不是退休的意思，他的英文解释就是shy
and reserved.
写作的时候，注意要学会用递进来进行预期的加强，比方说一个almost就是一个很好的方式。
答案： D
6. Comparatively few rock musicians are willing to laugh at themselves, although a hint of ________ can boost sales of video clips very nicely.
(A) self-deprecation
(B) congeniality
(C) cynicism
(D) embarrassment
(E) self-doubt
解析：又是一个前后转折，空格的信息在前面应该提到过，需要填入一种自嘲(laugh at themselves)的感觉，所以只有A选项合适。
注意B选项congenial表示随和的，这个单词大家经常跟congential区分不开。
boost这个单词要学会使用，表示提升、放大、加快等等，还要跟boast区分开。
答案： A
7. Parts of seventeenth-century Chinese pleasure gardens were not necessarily intended to look ________ ; they were designed expressly to evoke the agreeable melancholy resulting from a sense of the ________ of natural beauty and human glory.
(A) beautiful.. immutability
(B) cheerful.. transitoriness
(C) colorful.. abstractness
(D) luxuriant.. simplicity
(E) conventional.. wildness
解析：这道题就是传说中著名的agreeable melancholy，表示令人愉悦的忧伤。注意后面第二个空格这件事情要导致(resulting from)令人愉悦的忧伤，所以已经有了agreeable的部分(natural beauty and human glory)，所以我们填入一个负向的词汇。而前面说的是这个东西不是为了看起来怎么样，就应该不是看起来的那样，因此应该填入一个正向的词汇。因此选择B选项。
表示短暂的词汇，transitory, transient, ephemeral, fleeting, momentary, evanescent, 这些单词都是老生常谈了。
答案：B
