专题10 巧用虚拟语气
核心概念:什么是虚拟语气?为什么用它?
虚拟语气是一种动词形式,用来表示说话人所说的不是一个事实,而只是一种假设、愿望、建议或推
测。
· 表达复杂思想:让你能够谈论“如果……会怎样”的情景,拓展写作的深度和广度。
· 体现语言功底:正确使用虚拟语气是英语水平高的标志之一。
· 增强情感色彩:在表达愿望、建议或遗憾时,比直陈语气更具感染力。
· 直陈语气:I don't have a car, so I take the bus to work. (陈述事实)
· 虚拟语气:If I had a car, I would drive to work. (假设一个与现在事实相反的情况)
第二句话立刻让你的表达有了“层次感”。
1.If 条件句中的虚拟语气
与现在事实相反
If + 主语 + 动词的过去式 (be 动词用were) 主语 + would/could/might/should + 动词原形 假设现在
的情况,但事实并非如此
· 结构:If I were you, I would study harder.
· 解读:事实是“我不是你”,所以“更加努力学习”这个建议是基于一个不存在的假设。
· 写作运用:提出建议、表达愿望。
· If I had more time, I could read more books. (事实:我现在没有更多时间。)
· If he were here, he might help us. (事实:他现在不在这里。)
与过去事实相反
If + 主语 + had + 过去分词 主语 + would/could/might/should + have + 过去分词 假设过去的情况,
但事实并非如此
· 结构:If you had taken my advice, you would not have made such a mistake.
· 解读:事实是“你当时没有听我的建议”,并且“你已经犯了那个错误”。表达一种遗憾或责备。
· 写作运用:反思过去、表达后悔或总结教训。
· If I had worked harder, I would have passed the exam. (事实:我过去没努力,考试没及格。)
· She would have come to the party if she had not been sick. (事实:她当时生病了,所以没来。)
与将来事实相反
If + 主语 + 动词的过去式 或 were to + 动原 或 should + 动原 主语 + would/could/might/should +
动词原形 假设将来不太可能发生的情况
· 结构:If it rained tomorrow, the picnic would be canceled.
· 解读:说话人认为“明天下雨”的可能性很小,但万一发生了,野餐就会被取消。
识写作指导
· 写作运用:推测未来极小可能发生的事。
· If I were to become a millionaire, I would travel around the world. (成为百万富翁的可能性极
小。)
· If he should come late, what would we do? (他迟到的可能性不大。)
2. 宾语从句中的虚拟语气
· A. 表示“命令、建议、要求”的动词后:这些动词后的宾语从句中,谓语用 “(should) + 动词原
形”,should 常可省略。
· 常见动词:suggest, advise, propose, recommend (建议); insist, demand, require, request, ask (要
求); order, command (命令)。
· 例句:
· I suggest that he (should) go to see a doctor. (我建议他去看医生。)
· The teacher demanded that all students (should) be on time. (老师要求所有学生准时。)
· They insisted that the meeting (should) be put off. (他们坚持会议应推迟。)
· B. 动词wish 后的宾语从句:表示一种无法实现的愿望。
· 对现在的愿望:从句谓语用过去式(be 动词用were)。
· I wish I were a bird. (我真希望我是只鸟。)
· I wish I knew the answer. (我真希望我知道答案。)
· 对过去的愿望:从句谓语用 “had + 过去分词” 或 “could have + 过去分词”。
· I wish I had worked harder in high school. (我真希望高中时更努力一些。)(事实:过去没有努
力)
· He wishes he could have attended the concert. (他希望自己当时能去听那场音乐会。)
· 对将来的愿望:从句谓语用 “would/could/might + 动词原形”。
· I wish it would stop raining tomorrow. (但愿明天雨会停。)(表示一种期盼)
3. 主语从句中的虚拟语气
· 结构:It is + 形容词/过去分词 + that ... (should) + 动词原形
· 常见词:
· 形容词:important, necessary, natural, strange, essential, vital
· 过去分词:suggested, demanded, requested, advised, required
· 例句:
· It is important that we (should) protect the environment. (保护环境很重要。)
· It was suggested that a committee (should) be set up. (有人建议成立一个委员会。)
4. 状语从句中的虚拟语气
· as if / as though (好像,仿佛):从句谓语形式与wish 后的宾语从句相同。
· He talks as if he knew everything. (他说话的样子好像他什么都知道。)(事实:他并不知道)
· She looked as though she had seen a ghost. (她看起来像是见了鬼一样。)(事实:过去没见鬼)
