Me, my parents and my friends,Module 2,Unit 3,Language in use,Grammar,情态动词can,在表示“某人能做某事”时，可以用 “can+动词原形”表达。 如：I can dance. 如果表达自己不能做某事，可以在can 后直接加not,成为cannot, 也可以缩写为 cant。 如：I cannot (cant) play football. can没有人称和数的变化。不论表示谁 能(不能)做某事，都是用can (not)。,如果是询问某人能不能做某事，则要使用can的疑问形式，即将 can 提至句首。如： Can you speak Chinese? Yes, I can./ No, I cant.,其构成是： 肯定句: 主+can+动词原形 否定句: 主+cant+动词原形 一般疑问句: Can+主+动词原形？ 特殊疑问句: 特殊疑问词+一般疑问句？,Yes, 主+can.,No, 主+cant.,现在我们来总结一下：,eg: I can dance. 我会跳舞。 I cant dance. 我不会跳舞。 Can you dance? 你会跳舞吗？ What can you do? 你会干什么？,Yes, I can. 是的，我会。,No, I cant. 不，我不会。,注意： 否定形式 cannot 比缩写形式cant 要正 式。can 可以表示多种含义，而这里的 can所表示的都是能力。Can we swim? 好像与实际不符，其实现实生活中还是 有这种情况的。如反问句“我们会游泳 吗？当然会了。”（Can we swim? Certainly we can.）另外，can表示的“能 力”为现在的能力，而不能表示过去或将 来的能力，这一点一定要注意。,课堂小测验,Individual activity,_ are my classmates. A. This B. That C. These D. He 2. They are _ in a factory.
