考点11情态动词和虚拟语气情态动词和虚拟语气在历年高考中并非重点,但仍然是高中英语语法学习中的重难点。高考中 常常考查以下内容:考查情态动词的基本用法和推测用法;考查情态动词+havedone的用法; 考查if虚拟条件下的虚拟语气(包括省略if的虚拟条件句);考查含蓄虚拟条件下的虚拟语气; 考查特殊句式中的虚拟语气。1 .高考对情态动词的考查集中在情态动词的基本意义及“情态动词+ have done”结构语法上。2 .对虚拟语气而言,主要考查其在条件状语从句和名词性从句中的运用。一、情态动词【基础知识】情态动词本身有词义,但是没有人称和数的变化。情态动词有时态的变化,但是不能独立作谓语。情态动 词可以表示:能力、义务、可能性和允许等等意义;情态动词还可以用来给人们:提出请求、建议、意见 以及提供帮助等等。重点考向情态动词的基本意义(1) > can, could、表示能力,意为“能,会";could表示过去的能力,不表示是否做。, She can speak French fluently. 她能讲一 口 流利的法语。Our daughter could walk when she was nine old.我们的女儿九个月大时就会走路了。、can可用于肯定句中,表示客观或理论上的可能性。 He is confident a solution can be found. 他确信会找到解决方法。 An experienced teacher can make mistakes.一位有经验的老师也会犯错。 His demand is that the boy (should) go with them.他的要求是这个男孩和他们一起去。(表语从句) We agreed to the order that the task should be completed before5o' clock.我们都同意这个命令:在五点前完成这项任务。(同位语从句)Point 5在would rather后的宾语从句中,从句如果表示对现在或将来的虚拟,从句用一般过去时(be动词 一般用were);如果表示对过去的虚拟,从句用过去完成时。 I would rather I left now.我宁愿现在离开。 I would rather you came next month.我宁愿你下个月来。 I would rather he had passed the exam我宁愿他已经通过了 考试。考向三、虚拟语气在其他句型中的应用Point 1虚拟语气用于as if/as though引导的表语从句和方式状语从句虚拟语气从句谓语动词与现在事实相反过去式(be动词一般用were)与过去事实相反had+过去分词与将来事实相反would/ could/ might+动词原形 You treat them as if they were your parents.你对待他们如同他们是你的父母。(与现在事实相反) He acted as though nothing had happened.他表现得假设无其事。(与过去事实相反) They talked and talked as if they would never meet again.他们谈了又谈,好像永远不会再见面了。(与将来事实相反)【特别注意】当句子所表达的是真实的或极有可能发生或存在的事实时,从句要用陈述语气。 It sounds as if it is raining. 听起来像是在下雨。 .He talks as if he is drunk.从他谈话的样子来看他像是醉了Point 2在It,s(high/aboiit)time(that)句型中,that引导的定语从句通常用虚拟语气,即从句谓语动词用过去式(did)或“ Shoilld+动词原形"(Should不能省略),意为“该是的时候了” Jack is a great talker. It*s high time that he did/should do something instead of just talking.杰克是一个夸夸其谈的是时候他应该去做点什么而不是仅仅空谈了。 It is time that you went/should go to bed, Tom. 汤姆,你该去睡觉 了。Point 3虚拟语气用于if only引导的条件句或感叹句虚拟语气从句谓语动词与现在事实相反过去式或(be动伺用were)与过去事实相反had+过去分词与将来事实相反would/ could/ might-+动词原形 If only I were younger now!要是现在我年轻一些该多好啊!(与现在事实相反) If only you had worked with greater care! 要是你更细心地工作该多好啊!(与过去事实相反) If only I could go to the moon one day! 要是我有一天能到月球上该多好啊!(与将来事实相反)【特别注意】only if:意为“只有(才)'引导条件状语句,不用虚拟语气。 I told him he would succeed only if he tried hard. 我告诉他,只要他努力就会成功。经典好题1.
