if条件状语从句中虚拟语气.pptx

注意：如果动作在进行中，主句要用："主语+ would + have + 完成进行式动词 +…… ⑺、 If they had been here, he would have been speaking to them.(从句动词用 had been, 主句动词用 have been speaking)
① 与过去事实相反，在从句中用过去完成时形式表示。 ② 与现在事实相反，在从句中用过去一般时形式表示。 ③ 与将来事实可能相反，在从句中用过去将来时形式表示。
should, could 等加一个与从句一致的动词形式。
主句中则用情态动词 would,
例： ⑴、If I had come her yesterday, I would have seen him. ⑵、If I were a teacher, I would be strict with my students. ⑶、If it should snow tomorrow, they couldn't go out.

（二）、表示与过去事实相反的虚拟条件句。其句子结构为：从句：If + 主语+ had +过去完成式动词+ …… 主句：主语+ would (should, could, might) + have +过去完成式动词+…… 例如: ⑴、If you had taken my advice, you would not have made such a mistake.如果你听了我的劝告,就不会犯这样的错误。（事实上你没有听我的劝告） ⑵、I shouldn’t have been able to write such good novels if I hadn’t lived among the peasants for five years.如果我不是和农民生活了五年，就不可能写出这样好的小说。（事实上我和农民生活了五年） ⑶、If you hadn’t invited me, I shouldn’t have come to the party.如果你不邀请我，我就不会来参加你的舞会。(事实上你邀请了我) ⑷、If I hadn’t been ill yesterday, I might have come to school.昨天要是不生病，我是可能来上学的。（事实上我生病了） ⑸、If he hadn’t broken the law, he wouldn’t have been put in prison.如果他不违法的话，就不会被打入监狱。（事实上他违法了） ⑹、 If I had been your headmaster, I should have dismissed you from school. 我要是你们校长的话，就把你开除学籍了。（事实上虚拟语气的判断判断是真实条件句还是非真实条件句。只有在非真实条件句中才使用虚拟语气。通过句子意思，看假设的条件是否能够实现，能够实现是真实条件句，不能使用虚拟语气；假设的条件不能实现则是非真实条件句，要用虚拟语气。

if的用法总结及例句PPT

与“in case”的联系
in case可引导目的状语从句，相当于if引导的条件状语从句。例如：“Take an umbrella in case it rains.”（带把伞以防下雨。）
熟练运用if在固定短语和句型中应用
“If only”句型
表示对现在或将来的虚拟假设，通常用于表达遗憾或愿望。例如：“If only I had more time, I could finish the project.”（要是我有更多的时间，我就能完成这个项目了。）
典型例句
01
If it rains tomorrow, we will stay at home.（如果明天下雨，我们就呆在家里。）
02
If I were you, I would take the job.（如果我是你，我就会接受这份工作。）
03
If he had known the answer, he would have told me.（如果他知道答案，他就会告诉我。）
功能
用于表达在某种条件下会产生的结果或采取的行动。
结构特点
01
if从句+主句
if引导的条件状语从句通常位于主句之前，由if引导，后面紧跟主句。
时态呼应
02
03
虚拟语气
if从句中的时态通常与主句中的时态相呼应，表达相应的假设条件。
在if引导的虚拟条件句中，从句和主句的时态往往采用虚拟语气，表达与事实相反的情况。
“As if/though”句型
引导方式状语从句，表示比喻或虚拟的情况。例如：“She speaks English as if she were a native speaker.”（她说英语就像以英语为母语的人一样。）

IF条件句中虚拟语气(微课)PPT课件

03 if条件句中虚拟语气的用法
表示与事实相反的情况
结构
与现在事实相反，从句用“if+主语+动词过去式”，主句用 “would+动词原形”。
举例
If I were you, I would choose to study abroad.（如果我是你，我会选择出国留学。）
表示假设条件
结构
假设条件句可以用“if+主语+动词过去式+其他”，表示在假设条件下可能发生的情况。
虚拟语气与其他从句的区别
虚拟语气在if条件句中的用法与其他从句有所不同，需要注意区分。
例如，与if条件状语从句相比，虚拟语气在表达与事实相反的情况时，主句和从句的谓语动词形式会有所不同；与 if时间状语从句相比，虚拟语气更加注重假设和想象，而非真实的时间顺序。
05 if条件句中虚拟语气的练习与巩固
在主句和从句中，时态的一致性是虚拟语气的基本要求，否则会导致语法错误或语义混淆。
主从句时态对应关系
在if条件句中，虚拟语气的主句和从句时态有一定的对应关系。
如果主句是虚拟现在时，从句通常也是虚拟现在时；如果主句是虚拟过去时，从句通常也是虚拟过去时；如果主句是虚拟将来时，从句通常也是虚拟将来时。
02 if条件句中虚拟语气的形式
与现在事实相反的虚拟语气
总结词
表示与现在事实相反的情况，通常使用动词的过去式。
详细描述
在if条件句中，当表示与现在事实相反的情况时，从句使用动词的过去式（be动词用were），主句使用would+动词原形。例如，“If I were you, I would choose to study abroad.”（如果我是你，我会选择出国留学。）

与过去事实相反的虚拟语气
表示与过去事实相反的情况，使用过去完成时。
与将来事实相反的虚拟语气
表示与将来事实相反的情况，使用过去将来时。
在委婉语气中的使用
总结词
虚拟语气在if条件句中还可以用于表达委婉的语气，通过使用相应的时态和谓语动词形式来缓和语气或避免直接表达。
详细描述
在某些情况下，使用虚拟语气可以表达更加委婉的语气，使话语更加柔和、礼貌或含蓄。这种用法通常用于避免直接表达某些可能引起冲突或敏感的话题。
例子
If I were you, I would consider carefully before making a decision.（如果我是你，我会在做出决定之前仔细考虑。）这句话使用虚拟语气来委婉地提出建议或建议对方谨慎行事。
