三、单项选择（每小题1.5分，共9分）
19.【答案】C
考查动词时态。句意：我们得等到所有的准备工作都做好了才能开始工作。主句是将来时，从句用现在时或相当于现在的时态；现在完成时强调过去对现在的影响或动作从过去一直持续到现在。故选C。
20.【答案】C
考查动词时态及语态。句意：昨晚市场中心发生了一场火灾。幸运的是，目前还没有人死亡。根据last night可知，第一空用一般过去时态，break out（爆发）是不及物动词词组，无被动语态；根据so far（到目前为止），且句子主语和谓语动词之间是被动关系，所以第二空用现在完成时态的被动语态。故选C。
21.【答案】C
考查时态。句意：我想买那种衣服，因为有人告诉我他们很好洗。分析句子可知，从句内容为已经完成的动作，故用现在完成时；他们很好洗则是一个客观事实，故用一般现在时。结合选项，故选C。
22.【答案】B
考查动词。A. compromise：妥协；B. confirm：确认，证实；C. commit：犯罪，指派；D. concern：涉及，关心。句意：一些科学家并不否认外星人的存在，但是仍有待进一步证据证实。表示证实证据，故选B。
23.【答案】B
考查动词。句意为：考虑到各种谣言和猜疑，专家们进行了认真科学的调查，结果否定了在这个地区再一次发生地震的可能性。A项：谴责；B项：折扣，否认；C项：参加；D项：管理，负责，要价，控告。所以选择B项合适。
24.【答案】C
考查动词短语。句意：早期拓荒者们不得不在新的大陆上经历很多艰难困苦才能定居下来。A. go along with：和……相处；B. go back on：背弃；C. go through：经历，检查；D. go into：染上。由many hardships to settle on the new land可知，go through符合句意。故选C。
