Unit 1 I love sports 专题02 语法提升·易错题专项训练 · 内容导航 · 情态动词can Because与Because of 高频易错点、易错点提示、小练笔、答题点拨 易错精讲 情态动词can高频易错点01 can 是情态动词，没有人称和数的变化，在句子中不能单独作谓语，后接动词原形一起构成谓语，即 “can + 动词原形”。 一、can 的基本用法： ❶表示能力 (如体力和脑力方面)，意为 “能；会”。 例：Mike can play ping-pong. 迈克会打乒乓球。 ❷表示请求、允许，意为 “可以；能”。 例：—Can I watch TV? 我可以看电视吗？—Yes, you can. 是的，你可以。 ❸表示推测，意为 “可能”。 例：Sam can't be at home. 萨姆不可能在家。 用法口诀：表能力，可用 can，动词原形后边站； 不管主语如何换，can 的模样永不变； 一般疑问 can 提前，否定 can 后 not 添。 二、can的句型结构： 句型 结构 例句 肯定句 主语 + can + 动词原形 He can swim.他会游泳。 否定句 主语 + can't + 动词原形 She can't drive.她不会开车。 一般疑问句 Can + 主语 + 动词原形? Can you help me?你能帮我吗？ 特殊疑问句 疑问词 + can + 主语 + 动词原形? What can I do?你能做什么？ 易错点提示 一、核心结构易错：can 后面必须加动词原形 He can plays football. He can play football. 二、人称单复数易错：can 无人称、数的变化 不管主语是 I/you/he/she/it/we/they，can 永远不变形，不能写成 cans Tom and Amy cans dance. Tom and Amy can dance. 三、否定形式易错 正确否定：can not = can't（缩写） He not can draw.（否定词放错位置） He can not draw. / He can't draw. 拼写坑：不要写成 cant（少撇），正确缩写 can’t。 小练笔 一、单项选择。 ( ) 1．—Can you play ping-pong? —Yes, I ______.
