中考英语虚拟语气|知识点详细归纳
虚拟语气用来表示说话人的主观愿望、假想、建议、猜测,而非客观存在的事实,所陈述的是与事实相反 / 不太可能实现的情况。下面给大家详细归纳总结中考英语中最常考的几类,大家要经常复习巩固哦。
一、重点:if 引导的虚拟条件句(三大类)
结构:从句(假设) + 主句(结果)
1. 与现在事实相反
表示现在不可能、不真实的情况。
(1)从句:If + 主语 + 动词过去式(be 动词统一用 were)
(2)主句:主语 + would /could/should /might + 动词原形
例句:If I were you, I would go at once.如果我是你,我马上就去。(我不可能是你)
⚠ 必背:
(1)所有人称 be 动词都用 were,不用 was
(2)动词过去式不表示 “过去”,只表示虚拟
2. 与过去事实相反
对过去已经发生的事进行相反假设(后悔、遗憾)。
(1)从句:If + 主语 + had + 过去分词
(2)主句:主语 + would /could/might + have + 过去分词
例句:If you had come earlier, you would have met him.如果你早点来,就见到他了。(实际来晚了)
3. 与将来事实相反
对将来不太可能发生的事假设。
(1)从句:① If + 主语 + 动词过去式② If + 主语 + should + 动词原形③ If + 主语 + were to + 动词原形
(2)主句:主语 + would /could/might + 动词原形
例句:If it snowed tomorrow, we would build a snowman.如果明天下雪,我们就堆雪人。(不太可能下雪)
二、表格速记(必背知识点)
假设类型 | if 从句谓语 | 主句谓语 |
与现在相反 | 过去式 (be---were) | would/could + 动原 |
与过去相反 | had + 过去分词 | would/could + have + 过去分词 |
与将来相反 | 过去式 /should do /were to do | would/could + 动原 |
三、省略 if 的倒装结构(中考难点)
当从句中有 should / were / had 时,可以省略 if,把这三个词提到主语前。
1.If I were you ---Were I you
2.If it should rain ---Should it rain
四、固定句型(不用 if,直接考虚拟)
1. wish 后的宾语从句(希望…… 就好了)
(1)对现在希望:主语 + wish + 主语 + 过去式 (be→were)I wish I were a bird.
(2)对过去希望:主语 + wish + 主语 + had + 过去分词I wish I had studied harder.
(3)对将来希望:主语 + wish + 主语 + would/could + 动原I wish it would stop raining.
2. would rather 宁愿
(1)现在 / 将来:would rather + 主语 + 过去式I’d rather you came tomorrow.
(2)过去:would rather + 主语 + had + 过去分词I’d rather you hadn’t told him.
3. It’s (high) time that … 是时候做某事了
(1)从句一律用过去式(表虚拟建议)
---It’s high time you wentto bed.
4. suggest /advise/propose /demand/insist 等表 “建议、要求”
(1)从句用:(should) + 动词原形(should 可省略,直接用动词原形)
例句:I suggest that he (should) see a doctor.
⚠ 中考常考:这类词后面不能用 to do,也不用过去式,直接动词原形。
5. as if /as though 好像
(1)与现在相反:用过去式He talks as if he knew everything.
(2)与过去相反:用had + 过去分词He talks as if he had seen it.
五、含蓄虚拟语气(没有 if,但暗含虚拟),常通过 without, but for, otherwise 引出虚拟。
1.without /but for 要不是……Without your help, I would fail.= If there weren’t your help…
2.otherwise 否则I was busy. Otherwise, I would have come.
六、高频易错点
1.be 动词在虚拟语气中一律用 were,不用 was
✅ If I were you
❌ If I was you
2.主句只能用would / could / might,不能用 will /can
3.建议类动词(suggest, advise, demand…)从句:(should) + 动词原形,不能加 ed
4.区分真实条件句 vs 虚拟语气
(1)真实:If it rains tomorrow, I will stay at home.(可能下雨)
(2)虚拟:If it rained tomorrow, I would stay at home.(几乎不可能下雨)
