二.变化1. 错综时间条件句所谓错综，就是结构和我们的基本结构不一致，出现了从句用与过去事实相反，而主句则为与现在事实相反或与将来事实相反。
那么，我们就分别用各自的结构即可。
If + 主语+had done, 主语 +would/should/ could/ might do再将强调结构必须正确。
我们对比下面两个句子：If you had studied harder then, yoursituation would have been better.If you had studied harder then, yoursituation would be better now.注意：在错综时间条件句中，务必有明确的表示错综的时间状语，或者通过上下文能看出是时间的不同，否则，就必须按前面的基本结构套用。

虚拟语气在宾语从句中的用法
虚拟语气在宾语从句中的用法虚拟语气在宾语从句中的用法主要是表示一种与事实相反或不可能实现的假设、愿望、建议、命令等。
常用的虚拟语气形式有虚拟条件状语从句的"if"引导的虚拟语气、愿望句型的虚拟语气以及建议、命令等句型的虚拟语气。
1.虚拟条件状语从句的"if"引导的虚拟语气：在宾语从句中，如果条件句表达的是不可能实现或与事实相反的情况，那么主句的谓语动词就可以采用虚拟语气来表达。
例如：- I wish he were here.（我希望他在这里。
）其中，"were"是虚拟语气的过去式形式，用于表示与现实相反的情况，即实际上他不在这里。
2.愿望句型的虚拟语气：在宾语从句中，如果表达的是一种渴望或愿望，而该愿望实际上是不太可能实现的，那么常常使用虚拟语气来表达。
例如：- I would rather you came tomorrow.（我希望你明天来。
）其中，"came"是虚拟语气的一种形式，用于表示与现实相反的情况，即实际上他未来。
3.建议、命令等句型的虚拟语气：在宾语从句中，如果主句是一个建议、命令等，而宾语从句所表示的内容是不可能实现或与事实相反的情况，那么主句的谓语动词也可以采用虚拟语气来表达。
例如：- The teacher asked that he not be late for class.（老师要求他不要迟到。
）其中，"be"是虚拟语气的一种形式，用于表示与现实相反的情况，即实际上他经常迟到。
虚拟语气在宾语从句中的使用可以使句子更丰富多样，并能够准确表达说话人的想法、意愿和假设。
但需要注意的是，虚拟语气用法的正确性与自然性需要根据具体情况和语境来判断。
高中英语if条件虚拟语气
英语动词有三种语气：陈述语气、祈使语气、虚拟语气（用来表示说的话不是事实，或者是不太可能发生的情况，而是一种愿望，建议，假设的语气叫虚拟语气。
）虚拟语气的考点：1•条件句中的虚拟语气的用法；2.条件句中虚拟语气的倒装；3•名词性从句中虚拟语气的用法；4•几种特殊结构中虚拟语气的用法；5.虚拟语气时态的判定。
一、If引导的虚拟条件句区别：If it rains tomorrow，the crops will be saved.陈述语气If it rained tomorrow，the crops would be saved.虚拟语气真实条件状语从句与非真实条件状语从句真：eg .If he doesn' hurry up, he will miss the bus.如果他不快点，他将错过巴士。
（真实条件状语）（不是虚拟语气）If he is free, he will ask me to tell stories.如果他是空闲的，他会要求我讲故事。
（真实条件状语）（不是虚拟语气）非真：eg. If I were you, I would go at once.如果我是你，我马上就会去。
（非真实条件状语从句）二、虚拟语气在条件从句中：【例句】1.If you had come a few minutes earlier，you would have met him.要是你早来几分钟的话，你就能见到他了。
（与过去事实相反）2.lf it were sunny tomorrow, i would come to see you.明天要是天气好的话，我来看你。
（与将来事实可能相反）3.lf i were you, i would go at once.假如我是你的话，我会马上走。
（与现在事实相反，事实上我不可能是你）主从句的谓语形式（一）与现在事实相反的虚拟条件句表示与现在事实相反的情况，例 1.lf I were you, I would take an umbrella.如果我是你，我会带把伞。
(完整版)if引导的非真实性条件状语从句即虚拟语气
if 引导的非真实性条件状语从句即虚拟语气通过动词形式的变化来表示说话人对发生的动作或存在的状态所持的态度或看法的动词形式称为语气。
.英语中的语气分三种：陈述语气、祈使语气、虚拟语气。
虚拟语气表示说话人所说的话不是事实，而是一种祝愿，建议，与事实相反的假设或实际可能性不大的情况等（即非真实的假设）。
If 引导的条件状语从句分为真实和非真实条件句（虚拟条件句）。
真实条件句表示在假设的条件下，有可能实现的情况。
非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。
If he does n’t hurry up, he will miss the bus.( 真实条件状语)If he was free, he asked me to tell stories.（真实条件状语）If I were you, I would go at once.（非真实条件状语从句）If there was no air, people would die.（非真实条件状语从句）1）非真实条件句中虚拟语气的基本形式。
假设类型条件从句的动词结果主句的动词与现在事实相反动词过去式（be只用were）would/should/could/might + 动词原形与过去事实相反had+过去分词would/should/could/might + have + 过去分词与将来事实相反动词过去式/(should/were to)+动词原形would/should/could/might + 动词原形①与现在事实相反If I had time, I would go for a walk.如果我有时间，我就会去散步。
(实际情况：我现在没有时间，也不会去散步。
)If I were you, I would take an umbrella.假如我是你的话，我会带上雨伞。
(事实上我不可能是你。
)I would say no if someone asked me to be in a movie.假如有人请我当电影演员，我会表示拒绝。
虚拟语气在if条件从句中的用法
虚拟语气在if条件从句中的用法在if 引导的虚拟条件句中，若表示与现在事实相反，从句谓语用“动词过去式（be 的过去式用were ）,主句谓语用“would(should, could, might)+have+过去分词”；若表示与将来事实相反，从句谓语用“动词过去式（were to +动词原形，should+动词原形）”，主句谓语用“would(should, could, might)+动词原形”。
若把从句中were, should 或had移到句首，可省略从句的连词 if 并使用倒装语序.① If my lawyer ___here last Saturday ,he ____me from going.(NMET’89)A. had been ;would have preventedB. had been ; would preventC. were ;would preventD. were;would have prevented②---If he ____,he ____that food.--Luckily he was sent to the hospital imme diately.(MET’93)A. was warned ;would not takeB. had been warned ;would not have takenC. would be warned; had not takenD. would have been warned; had not taken③I didn’t see your sister at the meeting .If she ___,she would have met my brother.(NMET’94)A. has comeB. did comeC. cameD. had come④____it rain tomorrow, we would have to put off the visit to the Yangpu Bridge.(1994,上海)A. WereB. shouldC. WouldD. Will2．考查通过上下文或介词短语表示虚拟条件的虚拟语气的用法在英语中，有时假设的条件不是通过if 条件句表达出来，而是通过上下文或without, but for 等介词构成的短语表达，其谓形式要根据所假设的时间，与if 从句所表达的时间对应，确定主句谓语形式。
