　　答案解析：

　　1.B 解析：分析句子可知，本句为介词otherwise代替if引导的虚拟条件句，且根据句中的was可知，设空处所在句与过去事实相反，谓语应用would have done，故选B项。

　　2.A解析：分析句子可知，本句为介词短语Without computers代替if引导的虚拟条件句，且本句为对现在事实的假设，主句谓语应用would do，故选A项。

　　3.A 解析：根据从句中的谓语had been 可知，此句为对过去事实的假设，故主句谓语应用would havedone，故选A项。

　　4.A解析：根据主句谓语would have been可知，本句为对过去情况的虚拟。且根据从句句意“要是没有你的帮助”可知，从句主语应为it，设空处应为If ithadn\\\\\\\'t been for your help。选项中没有此表达，且根据if引导的条件句中含有were，should，had时，可将if省略并将were，should，had提前可知，应选A项。

　　5.A解析：当表示建议、提议、命令要求等名词作主语是，其表语从句和同位语从句中的谓语应用should do的形式，其中should可省略。分析句子可知effective measures与设空处为被动关系，所以应为should betaken，因should可省略，故选A项。

　　6.B 解析：根据主句中的would have happened 可知，本句为对过去情况的虚拟，从句谓语应用haddone，故选B项。

　　7.C解析：当表示建议、提议、命令要求等名词作主语是，其表语从句和同位语从句中的谓语应用should do的形式，其中should可省略。分析句子可知I与设空处为主动关系，所以应为should be，因should可省略,故选C项。

　　8.D解析：根据从句中的had not rained可知，本句为对过去情况的虚拟，主句谓语应用wouldhave done，故选D项。

　　9.D解析：根据主句中的could have warned可知，本句为对过去情况的虚拟，从句谓语应用had done，且根据选项可知，此处为if的省略，故选D项。

　　10.A解析：当表示建议、提议、命令要求等名词作主语是，其表语从句和同位语从句中的谓语应用should do的形式，其中should可省略。分析句子可知the government与设空处为主动关系，所以应为should free，因should可省略,故选A项。
