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.He2.They are _ in a factory.A.a factory worker B.factory workers C.factories workers D.factories worker,I.选择填空。,3._?Im a factory manager.A.How old are you B.How are you C.Whats your job D.Where are you,4.This is _ manager.He is very good to us.A.we B.our C.us D.ours5.He is from England.He is _ English teacher.A.a B.the C./D.an,Lucy can play the piano.(改为一般疑问句并作肯定回答)_ _2.Mike can swim.(改为否定句)_,II.句型转换。,Can Lucy play the piano?Yes,she can.,Mike cant swim.,3.They are from No.12 Middle School.(对划线部分提问)_4.I often go to school by bike.(改为同义句)_,Where are they from?,I often ride a bike to school.,5.Can you play chess?(否定回答)_.6.They can speak English.(变为否定句)They _ _ English.,No,I cant,cant speak,7.Tom can play football.(对划线部分提问)_ can Tom _?8.He can go now.(一般疑问句,否定回答)_ he _ now?No,he _.,What,do,Can,go,cant,1.她会说日语吗?是的,她会。2.他可以弹吉他。,Can she speak Japanese?Yes,she can.,He can play the guitar.,III.汉译英。,3.欢迎小明来到我们学校。4.我可以踢足球和打乒乓球。5.他们不能弹钢琴和骑马。,Welcome Xiaoming to our school.,I can play football and table tennis.,They cant play the piano or ride a horse.,Thank you!,
