Answer 1

1、c因为前面是一般现在时,所以不用最后一个答案,a表示动作,时态不定；b是动作已经过去,而不知道之后的情况；c则是说打扫这个动作是到现在为止已经完成,其结果直接影响到想在的状态（干净clean）
恩,2应该是选择c因为我记得有个短语是none of my business(与我无关）那么business应该有“事”的相关含义,而其他选项：action 行动 行为duty责任 （意思太大,事实上没这么严肃）way方式等都不符合句意的
3我选择b因为只有它有"安排"的意思,符合句意
4整句话是说只要让所有的东西处于他们原来的样子就好了,动词是put,她的宾语是all the things 间接宾语是where they there可以看作是一个where引导的宾语从句.后面的答案分别引导状语从句、定于从句、定于从句.
这样不知道你明白不明白哦,应该很清楚了吧,加油!
