　　1. Though Douglas designed and built the first computer mouse, he profited little from his invention because it does not become popular until his patent had already expired. (May 2011)

　　(A) it does not become

　　(B) it did not become

　　(D) of their not becoming

　　(E) they had not become

　　解析：该句无时间状语，可以通过未划线部分上下文动词形式，包括designed and built一般过去时，profited一般过去时，had already expired过去完成时来推断，推断画线部分动词的时态必须为过去的时态，再考虑到代词(见Chapter 2)。

　　2. Whenever Umberto sang in the shower, his voice rings throughout the house. (May 2010)

　　(A) rings (B) is ringing (C) would ring (D) ringing (E) has rung

　　解析：该句无时间状语，通过未划线部分上下文动词形式，推断画线部分动词的时态使用正确与否，由whenever(无论何时)引导的从句中sang为一般过去时，所以划线部分rings也应该为过去的时态。(提示：would do sth.可以表示过去将来以及过去常常双重含义。)

　　3. By next year the old vaudeville theater had been (A) converted into two small (B) theaters in which (C) films can be shown (D). No error (E)

　　解析：该句有明确的时间状语by next year，介词by与时间点连用，意思是到什么时间为止，一般情况用完成时。(提示：by+过去时间用过去完成时;by+现在时间用现在完成时;by+将来时间用将来完成时。)

　　4. According to (A) a recent study, the domestication of (B) cats had began (C) in the Middle East over (D) 100,000 years ago. No error (E)

　　解析：该句是简单句，谓语动词为had began,判断该句过去完成时正确与否。(提示：begin不规则变化begin/began/begun)

　　5. The memoirs of President Clinton begin with his childhood in Arkansas and culminate in his rise to the presidency.

　　(A) begin with his childhood in Arkansas and culminate

　　(B) that begin with his childhood in Arkansas and culminate

　　(D) have begun with his childhood in Arkansas and culminating

　　(E) began with his childhood in Arkansas and are culminated

　　解析：从选项的对比就可以看出，这道题考的是时态。(提示：memoirs：回忆录,自传)

　　6. The mayor claimed that a majority of the property owners would have favored her proposal if put to the vote.

　　(A) would have favored her proposal if put

　　(B) would have favored her proposal if it had been put

　　(D) favored her proposal if put

　　(E) favored her proposal if they were put

　　解析：从选项的对比就可以看出，这道题考的是时态。根据if引导的非真实条件句，可以发现这是考虚拟语气。(提示：对过去的虚拟从句应该用had done结构，主句用should/would/could/might + have + 过去分词。)

　　7. First run in 1867 and still taking place every summer, the Belmont Stakes, a horse race for thoroughbred three-year-olds, was one of the oldest races in the United States.

　　(A) was (B) is (C) were (D) are (E) has been

　　解析：从选项的对比就可以看出，这道题考的是时态。(提示：虽然这题中有两个时间状语in 1867和every summer，但是它们都不限制划线动词was，所以不能根据它们判断。句子意思：贝尔蒙特大赛马，一项专门为三岁大的纯种马举行的比赛，是美国最老的赛马之一。)

　　8. The bus would not have had to take (A) the long detour instead of (B) the main highway if the bridge did not become (C) treacherous in the aftermath of (D) an ice storm. No error (E)

　　解析：根据if引导的非真实条件句，可以发现这是考察虚拟语气的用法。(提示：对过去的虚拟从句应该用had done结构，主句用should/would/could/might+have+过去分词。)

　　9. Before she wrote the famous account of her experiences as (A) a Buddhist nun traveling (B) across Japan, Lady Nijo has lived (C) at the court of the Japanese Emperor for over (D) twenty years. No error (E)

　　解析：该句无时间状语，通过未划线部分上下文动词形式，推断画线部分动词的时态使用正确与否。(提示：由before(在…之前)引导的从句中wrote为一般过去时，所以主句动词应该为在过去之前的时态，即过去完成时。)

　　10. For our hike, my two companions and I (A) had chose (B) to walk along the Appalachian Trail, one of (C) the oldest and best-loved (D) hiking paths in the United States. No error (E)

　　解析：该句是简单句，谓语动词为had chose,判断该句过去完成时正确与否。(提示：choose不规则变化：choose/chose/chosen)
