3.语法 情态动词的用法 Ⅰ 【重难点分析】 情态动词(Modal Verbs )Ⅰ * 情态动词也可称为“情态助动词 (Modal Auxiliaries)”,因为它和基本助动词(be,do, have)都属于助动词类。 * 情态动词和其他动词连用,可表示说话人的语气。 * 情态动词可表达建议、要求、可能和意愿等。 * 情态动词没有人称和数的变化。 * 常用的情态动词有:can, could, may, might, must, shall, should, will, would这九大情态动词;其他的还有ought to, need, dare 等。 一、九大情态动词的时态关系: 1. 现在式 can -- 过去式 could 2. 现在式 may -- 过去式 might 3. 现在式 shall -- 过去式 should 4. 现在式 will -- 过去式 would 5. 现在式 must -- 过去式 must (常用had to来代替) 二、情态动词表示“可能”或“预测” (can, could, will, would, shall, should, must, ought to) (1)can 和 could 用于表示“可能”或“预测”: 1. He can’t be at home. (否定句) 他不可能在家。 2. Can the news be true ? (将情态动词 can 置于主语 the news 前就成疑问句) 这消息可能是真的吗?& [1] [2] [3] [4] [5] [6] 下一页
