( 《 新编英语语法教程 》 章振邦 2009 ) I wish I didn’t have to go to work today. ( 《 新编英语语法教程 》 章振邦 2009 ) 注意: I wish 和 I hope 都表示“希望”,但 I hope that… 并不表示假设意义,随后的动词形式除表示婉转口气外,很少用过去时形式。例如: I hope you are ready. ( 《 新编英语语法教程 》 章振邦 2009 ) I hope you ’re coming to our party. ( 《 新编英语语法教程 》 章振邦 2009 ) I hope you can do something to help her. ( 《 新编英语语法教程 》 章振邦 2009 ) We hope you will be very happy.

( 《 实用英语语法指南 》 周淑珍 2005 年 ) ( 3 )、用于 if only 引导的虚拟条件从句 if only 引导的条件句通常表达一种强烈的愿望或遗憾,其意思相当于 “ 但愿 ”“ 要是 …… 就好了 ” 等。其主句的谓语动词形式通常用 would/could/might+ 动词原形 ,表示与现在事实相反;或用 would/could/might have+ 过去分词 ,表示与过去事实相反。 例句: If only I had more free time, I would read more classical literature. (与现在事实相反 )( 《 实用英语语法指南 》 周淑珍 2005 年) If only he had not been so nervous ,he would have played it better.

( 《 新编英语语法教程 》 章振邦 2009 ) ( 5 )、用于 as if ,as though , 等引导的让步状语从句 如果主句中的谓语动词为实义动词,要用虚拟语气结构。其形式如下: 主句 +as if though)+ 主语 + ①were /was (或动词过去式) —— 表示与主句动作同时发生 ② could/would + 动词原形 —— 表示动作可能在将来发生 ③ had+ 过去分词 —— 表示从句谓语的动作发生在主句动作之前 例句: She speak English so well as if she were a native English speaker. ( 《 实用英语语法指南 》 周淑珍 2005 年) It seems as if she never knew fatigue. ( 《 新编实用英语语法详解 》 王增澄 2007 年) He talks about New York as if he had been there. ( 《 实用英语语法指南 》 周淑珍 2005 年) 注意: as if ,as though 引导的句中,如果主句中的谓语动词为系动词(如 appear , sound , feel , smell , taste 等),从句中即可用虚拟语气,也可以用陈述语气,用陈述语气居多。常用 as if 。 例如: It tastes as if it has plum in it.

( 《 新编实用英语语法详解 》 王增澄 2007 年) I was to have finished the work yesterday, but I didn't. ( 《 新编实用英语语法详解 》 王增澄 2007 年) ②以上动词的过去完成式加动词不定式也可以表示过去想做而没有做的事 She had meant to buy the furniture last week, but it rained. ( 《 新编实用英语语法详解 》 王增澄 2007 年) 虚拟语气的省略 1 、 省略主句 : 用 if only 引导的虚拟式的句子,通常都不出现主句,因为 if only=I wish If only he were here.=I wish he were here. ( 《 大学英语深层语法 》 王国栋 2005 ) If only you could marry me!= I wish you would marry me. ( 《 大学英语深层语法 》 王国栋 2005 ) 但 if only he comes in time. (陈述式) = I hope he will come in time. ( 《 大学英语深层语法 》 王国栋 2005 ) 2 、省略从句: 从句的意思可以推出来 Such mistakes could have been avoided. (省略 if I had been more careful )( 《 大学英语深层语法 》 王国栋 2005 ) (如果我更细致一些)这类错误本来是可以避免发生的。 You might live here forever.

Should he come here , we would discuss this with him.(=if he should come here…) Did we know her circumstances , we could do something to help her. if we knew her circumstances…) 某些虚拟语气的省略也属于含蓄虚拟语气 This same thing, happening in wartime (=if it should happen in wartime), would amount to disaster. ( 《 新编英语语法教程 》 章振邦 2009 ) Born in better times (=if he had been born in better times), he would have done credit to the profession of letters.

( 《 新编英语语法教程 》 章振邦 2009 ) 含蓄虚拟条件句 在含蓄条件从句中,假设部分可不用 if 引导的从句,而用介词短语或其他形式来表达 。例如 Without your help, we could not have succeeded. ( 《 新编实用英语语法详解 》 王增澄 2007 年) But for your help, we could not have succeeded ( 《 新编实用英语语法详解 》 王增澄 2007 年) He felt very tired yesterday, or he would have attended the party. ( 《 新编实用英语语法详解 》 王增澄 2007 年) 错综虚拟语气 在表示虚拟语气的句子中,条件从句表示的动作与主句表示的动作发生的时间并不一致,这时,谓语动词的形式要根据各自表示的时间来调整,这种现象叫作错综时间虚拟语气。 If he had followed the doctor’s advice, he would be quite all right now. 如果他过去听从了医生的嘱咐,他现在就会痊愈了 。(从句过去,主句现在) If they had left at nine, they would certainly be home by midnight. 倘若他们 (过去) 是 9 点钟出发了,那么他们肯定 (将) 在半夜零点就能到家。 If I were you, I would have gone to the theater that evening. 如果我是你的话,那天晚上就去看戏去了 。 (从句是现在,主句是过去) If my grandfather were alive now, he would be 100 next year.
