第一题,第一空是情态动词的用法,表客观可能性.第二空是用进行时态表示一种情绪,所以选B
第二题,she didn't want her parents to know what .what是宾语从句,主句的谓语动词是didn't want 为过去时从句的时态应该倒移一步所以不可能为现在时（一般现在,现在进行,现在完成）所以只能选B
第三题,by now意为现在,只有up to now 和up till now（到目前为止）才用现在完成时
第四题,suppose是假设,认为,后面很少跟虚拟语气,所以就是我认为你过去（在车祸中）正跑的很快
第五题,我觉得B也说得过去（但很少这样说）,但是用has been working 要好一些,或者就像楼上说的用过去完成时要更合适一点
