专题八 情态动词和虚拟语气
情态动词
一、情态动词 定义:情态动词是一种本身具有一定词义,但要与动词原形及其被动语态一起使用的词。它给谓语动词增添情态色彩,表示说话人对有关行为或事物的态度和看法,认为其可能、应该或必要等。 二、情态动词的特点 情态动词无人称和数的变化, 情态动词后面跟的动词需用原形,否定式构成是在情态动词后面加“not”。 个别情态动词有现在式和过去式两种形式, 过去式用来表达更加客气, 委婉的语气, 时态性不强, 可用于过去,现在或将来。情态动词属于非及物动词,故没有被动语态。
三、情态动词的语法特征 (1) 情态动词不能表示正在发生或已经发生的事情,只表示期待或估计某事的发生。 (2) 情态动词除ought 和have 外,后面只能接不带to 的不定式。 (3) 情态动词没有人称和数的变化,即其第三人称单数不加s。 (4) 情态动词没有非限定形式,即没有不定式,分词形式,也没有相应的动名词。 四、情态动词的基本用法

正 面 解 读
1.can, could的用法 规则1:表示体力或脑力(知识、技能)所产生的能力。 如: Her mother can speak French. He could read books in English when he was only five. 规则2:表示客观的可能性。如: Anybody can make mistakes. Man cannot live without air. 规则3:表示请求建议,用could 比 can语气更委婉 (回答用原形)。如: Could you wait a few days for the money? Could you be here at eight o'clock tomorrow morning?
A. lives C. has lived B. would live D. were to live
[解析] D 考查虚拟语气。根据主句中的wouldn't可判 断是虚拟语气。if引导的条件状语从句对将来进行虚 拟,从句用were to do或should do或过去式。所以选D。
