dfriendship参考答案.1答案：一岁的2答案：举世闻名的3答案：深远的，伸至远处的4答案：复查的5答案：大批生产的.答案：1.was made2.went3.saw4.had been destroyed5.could be used.1解析：从wrestle with the difficulties看出“要努力解决难以处理的事物”，第一空白处应该填入dilemma，说明“you”处于困境中，第二空白处应该填入premier表明“按照一定的程序对付困难是很重要的”。approval“赞成”；unconscious“无意识的”；diagram“图表”；explicit“清楚的”；absence“缺席”；thankful“感激的”。a、b和d项与本题无关。答案：c2解析：从第一个逗号前面的句子看出第一空白处应该填入which，构成非限制性定语从句，而不能够填入that，修饰microscope。第二空白处应该填入donated，donated organs“捐献的器官”。d项符合句意“他们发明了一种特殊的显微镜，用来对患者进行器官移植手术，这是一个专利”。thrilled“感到兴奋的”；adjusted“已经调整的”；updated“更新了的”。答案：d3解析：从though引导的从句看出第一空白处应该填入corresponding，表示“尽管在两周前我们俩分手了，但一直通过手机互相通信”；第二空白处应该填入outspoken表示“直言不讳”，后半句and meanwhile.“同时他送给我一个微波炉作为生日礼物” 是对“直言不讳”作进一步介绍和说明。purchase“购买”；adequate“适当的”；guarantee “担保”；handy“便利的”；embarrass“使困窘”；electronic“电子的”。a、c和d项与本题无关。答案：b4解析：从the navy和 to hit the jets of the enemy despite mist推测出句意为“尽管出现了薄雾，但是在望远镜的帮助下，海军用导弹击中了敌机”。看出第一空白处应该填入telescopes，第二空白处应该填入missiles，符合军事常识。d项是干扰项，colleagues“同事”；specialists“专家”，但是与hit吻合不起来。medium“媒体”；certificate“证书”；telescopes“望远镜”；missiles“导弹”；microscope“显微镜”；database“数据库”。答案：b5解析：从experiment看出第一空白处应该填入outcome(结果)，从the disease可知第二空白处应该填入cure(治疗)。b项符合句意“实验的结果是他无意中发现了用于治病的叫做青霉素的霉菌”。issue“问题”；enterprise“事业”；rescue(拯救)和 kill(杀死)的宾语不能是 disease。答案：b6解析：seat vt.使就座，be seated表示“坐着”的状态，此句为“请保持坐着，直到飞机完全停下”，remain为系动词，remain seated表示“保持坐着”。答案：d.1解析：由.because it was not _ yet.可知，司机还不打算开车。答案：d2解析：由第二段首句“when all the seats were taken，.”可知，司机不打算开动汽车是因为要等所有的座位坐满。答案：b3解析：由下句中was stolen及第一段最后一句.she stopped crying.可知应选tearfully。答案：a4解析：由倒数第四段中“.took out her remaining money.”可知，钱被偷了。答案：c5解析：由本句中“the other half was hidden under her blouse”可知，幸运的是，还剩下一些钱。答案：d6解析：由前面出现的tired and sad，.可知，她几分钟后不哭了，但是仍然不高兴。答案：c7解析：由本句中.he had spent all his money when he had accidentally got on a wrong bus.可知，老人因为无意中上错汽车而花光了所有的钱，因此，在向售票员解释。答案：a8解析：由下一句中.to let him take the bus home可知是售票员命令老人下车。get off意思是 “下车”，符合语境。答案：a9解析：从.almost in tears.可知，老人“祈求” 售票员让自己搭车回家。答案：a10解析：由上文中.she ordered the old man.可知，因为老人没钱买票，售票员命令其下车。这里司机重复的应是售票员的命令。request“请求”；action“行动”；suggestion“建议”；command“命令”。答案：d11解析：由句意可
