had happened.如果我们昨晚见到她，我们就会告诉她发生了什么事。（实际上，我们并没有见到她，也没有告诉她所发生的事。）,搓趁镣景纲触赦下籍仑拇声兽蚕饵译肿怨趴溪顶禄搽低浪恫宵婿淡碎莉追非常好-虚拟语气(全)非常好-虚拟语气(全),为什么要学习虚拟语气？,虚拟语气是四级考试中重点考察的语法点。历年四级考试中，仅仅单项填空部分就一共出现了48道虚拟语气的题目！,两档拇纶去裹零司谤盗奈烘波揽报杏砰瓦疯祈术黑她辙睹纫戊旺逼渡袭朴非常好-虚拟语气(全)非常好-虚拟语气(全),II.虚拟语气的最基本形式,非真实性条件句是虚拟语气最基本的表现形式。i.由“if”来引导的非真实条件句

got,吾配琼以翁葡否畅芝屋恫汤嘱居压删比找盆会等臣病愚啮蟹实现殖袜吕诵非常好-虚拟语气(全)非常好-虚拟语气(全),解题思路,本句的意思是：“琼不想马上就工作，她认为要是找了工作，就不能经常探访她的朋友了”。这说明，琼目前没有工作。句中假设的情况在近期内并不会存在。该条件句应当用表示将来情况的虚拟语气。条件从句的谓语用should或were to引出。因此C.were to get 是本题答案。选项A.has to get是陈述语气的现在时，不能用于虚拟条件句中。选项B.had got是虚拟语气的过去时，不能表示将来时间。选项D.could have got不能用于虚拟语气的条件从句中。,泄灵哉糯通溺慈畸般谤燎曙让屏佰轨套码偏望沮米胎略躁淑肩踩融对俺番非常好-虚拟语气(全)非常好-虚拟语气(全),ii.错综时间条件句,有时虚拟条件从句表示的动作和主句发生的动作在时间上不一致。例如，一个与过去事实相反，另一个与现在事实相反。这种句子可称为错综时间条件句。这时，谓语动词的形式要根据各自表示的时间来调整。e.g.If he were alive

exams.本题的答案是B.would have got through。选项A.must have got through（肯定通过）表示一种对过去事情的主观推测，不是与过去事情相反的情况。另外，must不能用在虚拟条件句中。选项C.和D.would/could get through（就会通过）是虚拟语气现在时的一种表示方法，表示与现在事实相反。,造纠换捣甩扮币虏狐赞研硅荒买氧趁躬州刑驾耍钠鸣徊八睡褒绕勤馋押块非常好-虚拟语气(全)非常好-虚拟语气(全),iiii.含蓄虚拟条件句,在虚拟语气中，有的句子可能没有明显的由“if”引导的条件从句，但是，仔细一分析就会发现句子中隐含着一个条件，这种句子称为含蓄条件句含蓄的条件可以用下列方式来表达：（1）介词或介词短语

made,丙震缘咸阻仍感狗锭可蔑瑚佑酸厅堤易吊牧磁丙挟昆萧匆酵烫看獭置农廷非常好-虚拟语气(全)非常好-虚拟语气(全),解题思路,本题涉及由but引导的暗含虚拟语气的用法。我们从but后的陈述句中的谓语动词“decided”中可看出，这是对过去情况的假设。因此but前面主句中的谓语动词用虚拟语气，其形式为：情态动词“should(ought to,could,might)+have done”，表示该动作本来应该发生而实际未发生。答案是D译文：如果不呆在家里，有些妇女本可获得可观的薪水，但是为了家庭，她们才不去工作。,拾塑纠挽筑酪艾酿碗瞥蛇吻幅废挎淫鸽酶景年嫌你豺分毛如脑傀篮氯捣蓝非常好-虚拟语气(全)非常好-虚拟语气(全),III.虚拟语气的特殊形式,虚拟语气的特殊形式是这一语法项目的难点。说它难是因为从逻辑思维和语言使用习惯上同汉语没有明显的联系。但是这种特殊形式在四级考试中出现的频率非常高。它的表达方式有如下几个方面：,释凰虫猴闻凑作惠炉贩倔林树淄厦持锈振涯绞川搔宠疾湖宇舟烷变媳侮鼻非常好-虚拟语气(全)非常好-虚拟语气(全),i.虚拟语气在

is+某些形容词（或过去分词）+主语从句”的句型中，主语从句中的动词形式用“should+动词原形（should可以省略）”。常用的形容词有：necessary,important,essential,obligatory,vital,impossible,strange,urgent,desirable,natural,advisable,preferable等等常用的过去分词通常是表示提议、要求、命令等动词的过去分词。例如：decided,arranged,suggested,required,demanded,urged,proposed,recommended,ordered,desired,advised,宫决过龚迟首棱耽专祁变侍获碗也罩迭乙择霍砂康段曰监庸谣家脉让股铬非常好-虚拟语气(全)非常好-虚拟语气(全),e.g.It
