A．Were B．Would C．Will D．Should 【解析】　句意：如果明天下雨，我们将不得不取消足球比赛。根据主句中的would have以及从句中的tomorrow可知此句为与将来事实相反的虚拟语气。所以从句谓语为should/were to＋do；本句省略了if，故应把should提句首；A项应为Were it to rain才正确。 【答案】　D 4．Had Paul received six more votes in the last election，he our chairman now. A．must have been B．would have been C．were D．would be 【解析】　条件从句省略了if，把助动词had提到主语前面，表示对过去情况的假设，而主句是对现在情况的假设，所以此处应用“would＋动词原形”。 【答案】　D 5． he had not hurt his leg，John would have won the race. A．If B．Since C．Though D．When 【解析】　句意：若是没伤着腿，约翰就赢得这场比赛了。根据句意，虚拟语气中对过去作相反假设，if从句用过去完成时，主句的谓语动词用过去将来完成时。四个选项中只有A选项符合题意。 【答案】　A 6．Maybe if I science，and not literature then，I would be able to give you more help. A．studied B．would study C．had studied D．was studying 【解析】　句意：也许如果当时我学习的是理科而不是文科的话，那么我(现在)就可以给你更多的帮助了。根据then可以确定此处表示与过去事实相反，故if引导的从句部分用had done。 【答案】　C 7．If I hadnt forgotten the article，I it to you now.
