1。表示否定和疑问的猜测只能用can,后面用must have表示，他一定已经被选为足球队队长了 2。A, must have been to 表示他一定偷了，予意思不符 B, needn`t have done 表示本来不必做某事，但是做了 C, should have done 表示本应该做某事，但是没有做 D, couldn`t have done 表示不可能做某事 could have done 表示本能够做某事，却没有做 3。
用过去分词，表示“原本所计划的” 4。在i think引导的从句中，从句的否定要提前放在主句 able to 表示偶然的能力，而can表示一贯的 例如：I was able to finish the work on time。 I can sing 6。
who finished是定语，修饰students，settled和waited是谓语，由于动作发生在过去，所以用过去时 7。turn to sb for help向某人求助 sb是to 的宾语，所以用whom 8。When and where 的用法有点特殊，它们的谓语之用单数 9。
这个句子中的主语是no one，意思是“百货店里没有人，除了我和tom，知道director将要辞职”，可见，主语是no one 。
1。考察情态动词表推测，疑问句中的“可能”只能用can(could)。can(could) have done表示对过去的推断，must have是must have done的省略，表示对过去有把握的推断。当情态动词后有be， have时不能省去 2。
couldn't have been to表示过去不可能。must不能用在否定句中，needn't have done,表是本不需要做某事；should have have done表是本应该做某事而实际上却没有做 3。有省略，。。。as(all was)planned。
4。句意是：你在这儿总是做得很好，这次我想不会不同吧。当think suppose, believe等后面的宾语从句的否定要装移到主句之中 5。was able to表示过去具体一次动作做成了。be able to do sth表设法成功的干成了某事，不仅具有这种能力，而却也做了这件事。
can,could只表具有这种能力，不强调结果 6。settled与waited并列作the students的谓语。 7。引导词代替e single person在从句中作turn to的宾语而省略,所以省去关系代词。选B 8。yet暗示要用现在完成事。
并且后面是指一件事情度假，用单数。 9。Tom and I只是but（除了）的宾语，no noe才是句子的主语。当but,except,as wellas with,together with, along with , like(象。。。
一样的）等来修饰主语要和主语，保持一致，不受后面词的影响，此句中主语是no one所以用单数 。
