　　③先行词与定语从句被谓语分隔开来。此时，先行词通常是句子的主语，因定语从句较长，主句谓语较短，为使句子平衡，常将定语从句移至谓语之后 如：

　　答案与详解

　　1.A.条件句表示与现在事实相反的虚拟。

　　2.B.条件句表示与过去事实的虚拟。

　　3.A.条件句表示与未来事实的虚拟。

　　4.B.条件句表示与未来事实的相反。

　　5.C.条件句表示与现在事实的虚拟。

　　6.D.条件句表示与现在事实的虚拟。

　　7.B.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 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、的but that、的without, 由连词but、的副词otherwise 、的比较级、的形容词、的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)。

　　12.D.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。

　　13.A.从句对过去的虚拟。

　　14.B.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、的愿望、的建议、的请求、的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。

　　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。

　　21.D.

　　22.D.

　　23.C.

　　24.A.

　　25.D.

　　26.(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)+动词原形。

　　30.A.表示与现在相反的虚拟。

　　31.A.as though引导的与过去相反的虚拟。

　　32.D.felt是过去式，所以该句是由as though引导的与过去相反的虚拟。

　　33.D.as if引导的与现在事实相反的虚拟。

　　34.A.as if引导的与过去相反的虚拟。

　　35.C.

　　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。

　　41.(B)It is time that是一种要求从句用虚拟语气的常见句型。虚拟语气形式为动词的过去式。

　　42.(C)

　　43.(C)otherwise用来表示一种含蓄的虚拟假设，因为是对过去(yesterday)的情况的假设，所以应该用would have come形式。

　　44.(B)所给的四个选项中没有一个表示对未来的情况的虚拟的形式should+动词原形，或是were to do，因此可以断定if引导的条件句在这里最真实的条件句，用一般现在时表示一般将来时，故(B)是正确答案。

　　45.(A)这是一个混合虚拟语气的句子，if条件句表示的是对过去情况的假设，而主句是对现在(now)的情况的假设，故用would tell形式。

　　46.C.

　　47.C.

　　48.C.

　　49.B.would rather引导的虚拟语气其谓语用过去式。

　　50.D.would as soon引导的虚拟语气，其谓语动词也用过去式.

　　51.B.

　　52.B.

　　53.B.

　　54.B.

　　55.C.注意单词otherwise引导虚拟语气。

　　56.C.同上。

　　57.A.注意词组for fear that

　　58.A.注意without

　　59.C.

　　60.C.

　　61.D.

　　62.B.

　　63.D.

　　64.A.

　　65.D.
