2. They will go home for winter vacation as soon as they ____ their exams.
A. have finished
B. finish
C. finished

"as soon as" 表示"一...就..."，引导时间状语从句，主句用一般将来时，从句用一般现在时表示将来。则使用finish。 winter vacation 寒假

4. Please give Jim the schedule for tomorrow's conference when he ____ back. He is to chair the conference.
A. will come
B. come
C. comes
D. came
A."will come" 是将来时态，但在这个结构中不适用。
B."come" 是原形，但没有明确使用现在时态。
C."comes" 是现在时态的第三人称单数形式，适合用在时间状语从句中表示将来的动作。
D. "came" 是过去时态，不适用于表示将来的动作。
因此，正确的答案是：C. comes（当Jim回来时，请把明天会议的时间表给他。他将主持这次会议。）
chair 主持 conference （大型）会议
5. ____ five minutes earlier, you would not have missed the last train for Shanghai,but you were late.
A. Had you come
B. Do you come
C. Did you come
D. Should you come
分析：
A. "Had you come" 是过去完成时的倒装结构，正确地表达了与过去事实相反的假设。
B. "Do you come" 使用了简单的现在时态，不符合表达与过去事实相反的假设的需要。
C. "Did you come" 使用了简单的过去时态，同样不符合表达与过去事实相反的假设的需要。
D. "Should you come" 使用了情态动词 "should"，这在第三条件句中通常表达未来的可能性或建议，而不是与过去事实相反的假设。
因此，正确的答案是：
A. Had you come（如果你早来五分钟，你就不会错过最后一班去上海的火车，但是你迟到了。）

7. ____ the former president's supporters went out in streets to express their anger and dissatisfaction
A. A small amount of
B. A large number of
C. A little bit of
D. A great deal of
A. "A small amount of" 通常用于不可数名词，表示数量少。
B. "A large number of" 用于可数名词复数，表示数量多，适合用来描述大量的人。
C. "A little bit of" 用于不可数名词，表示一点点，数量不大。
D. "A great deal of" 通常用于不可数名词，表示大量的，但在这个句子中不适用，因为 "supporters" 是可数名词。
由于 "supporters" 是可数名词的复数形式，我们需要一个用于可数名词的短语。因此，正确的答案是：
B. A large number of（大量的前总统的支持者走上街头表达他们的愤怒和不满。）
这个短语正确地描述了有很多人参与了这一行动。
"A large number of" 意为 "大量的"，用于描述数量很多的人或物。
"the former president's supporters" 意为 "前总统的支持者"，表示特定的一群人。
"went out in the streets" 意为 "走上街头"，表示某些人前往公共场所。
"to express their anger and dissatisfaction" 意为 "表达他们的愤怒和不满"，表示这些人的行为目的。
8. To be honnest, today's dinner was just so-so. It wasn't such a good one ____ promised by the boss.
A. that B. which C. as D. what
正确答案是 C. as，因为它用于表示比较，特别是在结构 "not as ... as" 中，用来比较两个程度或性能。在这个句子中，"as" 用来比较实际的晚餐和老板所承诺的晚餐。完整的句子是：
"To be honest, today's dinner was just so-so. It wasn't such a good one as promised by the boss."
这句话的意思是说，今天的晚餐只是一般般，并没有达到老板所承诺的那样好。
9. So many people ____, the meeting had to be put off.
A. being absent B. to be absent C. were absent D. had been absent
"being absent" 是一个现在分词短语，可以用来表示原因，适合放在句首。
正确的答案是 A. "being absent"，因为它是唯一一个可以作为分词短语放在句首，表示原因的选项。完整的句子是：
"Being absent, so many people, the meeting had to be put off."
这句话的意思是说，因为很多人缺席，会议不得不被推迟。
10. We often advise him not to drink more ____ is good for his health.
A. as B. that C. than D. but
正确的答案是：C. than（我们经常劝告他不要喝比对他的健康有益的量更多的酒。）句子中的 "not to drink more than is good for his health"
表示不要超过对他的健康有益的饮酒量。这里的 "than" 引导了一个省略了 "it is" 的比较状语从句，完整的句子是 "not to drink more than it is good for his health"。
11.Did Charles vote in the last election?No, he wasn't _____。A. enough old then B. then enough old C. old then enough D. old enough then
正确的选项是 D. old enough then.
"Old enough" 是形容词短语，用于表示达到足够的年龄或程度。
"Then" 表示那个时间点，用于强调时间的特定性。
因此，"he wasn't old enough then" 意思是在上次选举时，他还没有达到足够的年龄，因此没有投票。
12. By no means ____ look down on those who are less lucky in life than we are.
A. we should B. should we C. we should not D. should we not
正确的选项 B.should we
By no means should we look down on those who are less lucky in life than we are? (我们绝对不应该看不起那些比我们运气差的人。)
13. He didn't feel like ____ that day so he stayed indoors reading.
A. working B. works C. to work D. worked
在这个句子中，"feel like" 后面应该跟一个动名词，即以 "-ing" 结尾的词，来表示想要做某事的感觉。这是因为 "feel like" 这个短语后面通常不跟不定式 "to + base form" 的结构，而是跟动名词作为宾语。
所以，正确的选项是：A. working（那天他不想工作，所以他待在室内阅读。）
这个句子的结构是：
主语：He 谓语：didn't feel like 宾语：working
结果状语从句：so he stayed indoors reading
选项C "to work" 是不定式形式，通常不用于 "feel like" 之后。因此，正确答案是 A. working。
14. He decide to go for a sailing holiday ____ the fact that he was usually Seasick(晕船)
