19、现在事实的虚拟。 7B这个句子中含有一个省略if，把助动词提前到主语they之前的虚拟条件句，该条件句表示对过去情况的假设，而主句中by the time they were finished 表明主句也应该是对过去发生的情况的假设，因而应该选（B）would have lost为正确答案。 8（D）这道题目是一个混合虚拟语气的句子。条件句省略了if，把助词had提前到主语前面，表示对过去情况的假设，而主句中now表明了对现在情况的假设，所以应选would(should, could, might)+动词原形这种表达形式。四个选项中只有（D）是正确表达形式，故为正确答案。 9（D）until
20、recently，因此（D）是正确答案，而主句是隐含的对现在情况的假设，该句是一个混合虚拟条件句。 10（B）假设的情况有时不是用一个条件句表示，而是隐含在一个由介词如but for、but that、without, 由连词but、副词otherwise 、比较级、形容词、独立主格等表示的上下文中。本句主句表示对过去情况的假设，但事实上由于英语考试而没有去成，即若不是因为英语考试，我本可以去听音乐会，所以应选But for为正确答案。 11（C）题目中的第一句话表示的是现在真实的情况，而第二句话中所要表达的是应该做但事实上没有做的事，这种情况导致第一句话中真实情况的发生，故If only条件
21、句假设的是过去一种情况，因此应该用had +过去分词，所以正确答案是（C）。 12D注意主句now表示现在的时间状语，所以主句是对现在虚拟，从句是对过去虚拟。 13A从句对过去的虚拟。 14B从句表示虚拟，而主句是事实。 15（D）it是形式宾语，urgent是宾语补足语，that引导的从句是真正的宾语从句，该从句的内容被认为是urgent（急迫的），这样从句的谓语动词要求用虚拟语气形式，即should（可以省略）+动词原形。因此，本题正确答案是（D）。 16（C）在表示要求、愿望、建议、请求、命令等含义的名词同位语从句中，从句谓语动词要用虚拟语气形式，即should(可以省略)+动词原形。
22、17（D）本道题目的前半句话是对过去情况的一种假设，但事实上并没有发生，而事实上没有发生的真实原因是句子的后半部分由but引导的转折句所表述的真实。因而but所引导的句子中应该用表示志过去事实相符合的表陈述的时态，即一般过去时。 18（B）此题要求在if从句中选择适当的动词形式，以主句中的动词apologize(抱歉)来看，if从句中表达的内容应该是过去做的事，因此可以排除（A），因为（A）是现在时。（C）中should+have+过去分词结构表示本来应该做却没有做的事，在此不合题意。（D）选项中的might+have+过去分词表示对过去发生的事情很不肯定的猜测，它表达的内容还不能成为事实，所
23、以藉此道歉真是不知从何说起，因此此处也不合题意。（B）had offended表示当时已经发生了的动作。这是复杂条件句：apologize 是现在，而条件句是表示对过去假设的条件句。 19（A）该句也是一个复杂条件句（或称作混合虚拟条件句）。条件句表示对过去情况的假设，而主句表示对现在情况的假设，但事实上却与此相反，所以正确答案应该是（A）。 20（A）as if引导的从句要求用虚拟语气，表示同时或将来的情况，动词要用过去式（be动词用were）或would(could等)+动词原形，本句话中指的是当时的情况，所以要用过去式，故（A）是正确答案。 21D 22D 23C 24A 25D 26（
24、B）had not occurred表示对过去的虚拟，条件句中要用过去完成式，主句中要用should(would, could, might)+动词原形的过去分词。 27（B）had hoped是常见的要求其后的宾语从句用虚拟语气的句型,虚拟语气would+动词原形。 28（C）表示对过去情况的假设，主句动词形式为would(should, could, might)+have+过去分词，条件句为过去完成式，if可以省略，但要把had提前主语前面。（B），（D）的表达不符合英语表达习惯，所以（C）是正确答案。 29（A）suggest后面的从句要用虚拟语气形式，其形式为should（可以省略）
25、+动词原形。 30A表示与现在相反的虚拟。 31Aas though引导的与过去相反的虚拟。 32Dfelt是过去式，所以该句是由as though引导的与过去相反的虚拟。 33Das if引导的与现在事实相反的虚拟。 34Aas if引导的与过去相反的虚拟。 35C 36（D）would rather后接从句要求用虚拟语气，形式为过去式，表示对现在或将来的假设，或为过去完成式表示对过去的情况的假设。 37（C）who引导的定语从句中的现在完成时表示动作业已发生，所以主句中表示的虚拟是针对已经发生了的行为，所以应该用过去完成式表示对过去的虚拟。 38（B） 39（C）这是一人含蓄虚拟条件句，通过介词短语without,表示潜在的一种假设，而主句中的情况也早已经发生，所以是对过去情况的一种假设，因此用would not have been achieved这一形式。 40（D）连so that引导的从句中要求用虚拟语气，表示一种假设，形式为might+动词原形。
