Can you read the story book with me?（你可以和我一起阅读故事书吗？） Yes, I can. （是的，我可以。） 3. 特殊疑问句：特殊疑问词 + can + 主语 + 动词原形 + 其他？ What can you read?（你能读什么？） 易错点提示 1.can后误用动词三单/动名词，必须接动词原形 2.疑问句忘记把can提前 3.否定缩写`can't`不要漏撇号，不要写成cant。 经典例题 —____ I read the book with you? —Sure. A. Do B. Can C. Am 点拨 答案：B 【解析】句意：你可以和我一起读书吗？当然可以。 答语sure表同意对方请求，用情态动词can表许可；do引导一般疑问句需搭配实义动词原形构成疑问，am后面不能接动词原形，因此选B。 小练笔 01 一、单项选择。 ( ) 1. Mike can ____ a science book. A. read B. reads C. reading ( ) 2. —Can you help me? —Yes, I ____. A. can B. can't C. do ( ) 3. What ____ you do to remember poems? A. do B. can C. are ( ) 4. The boy ____ draw pictures for his poem. A. cans B. can C. is can ( ) 5. ____ I call Lingling later? A. Can B. Am C. Does 二、按要求改写句子。 6. I can share the cupcake with Joe.（改为一般疑问句） 7. She can remember the first word.（改为否定句） 8. They can read books together.（对划线部分提问） 9. Can he finish reading the story?（做否定回答） 10. can, with, we, it, read, together（连词成句） 情态动词should（表建议、劝告）高频易错点02 一、概念： “should”意为“应该”，用来给出建议、劝告；同样无人称、数的变化，后面必须接动词原形；常用于别人生病、学习遇到困难时给出建议。 二、句型结构： 结构 例句 肯定句：主语+should+动词原形+其他 You should have a good rest. （你应该好好休息。） 否定句：主语+should not(shouldn't)+动词原形+其他 You shouldn't stay up late. （你不应该熬夜。） 一般疑问句：Should+主语+动词原形+其他？ Should I draw a picture? （我应该画一幅画吗？） 易错点提示 1.should后加三单、ing形式，必须用原形 2.主语第三人称单数，should不用变形 3.建议场景不要混用must；should是委婉建议，must是强制命令。 经典例题 ( ) You ____ drink more warm water when you have a cold. A. should B. are C. have 点拨 答案： A 【解析】句意：当你感冒时应该多喝温水。这是针对感冒给出建议，用should+动词原形drink；are后面不能直接接动词原形，have不能直接搭配动词原形表建议。 小练笔 02 一、单项选择。 ( ) 1. Guoguo ____ draw pictures to remember the poem. A. should B. shoulds C. to should ( ) 2. You ____ go to school if you feel very bad. A. should B. shouldn't C. can ( ) 3. What ____ I do to memorize this poem? A. should B. am C. does ( ) 4.

You ____________ run outside if you are ill. 10. Students ____________ finish reading their books on time. 特殊疑问句（what引导，询问事物、动作）高频易错点03 一、概念： 用特殊疑问词what提问，针对事物、动作、书籍内容、行为提问，回答不用yes/no，直接给出具体信息。 二、句型结构： 结构 例句 现在进行时：What + be动词 + 主语 + doing? What are you reading? （你正在读什么？） I'm reading a science book.（我正在读科学书。） 易错点提示 1.现在进行时漏加ing 2.混淆be动词、助动词；有be动词就不用do/does 3.询问书籍内容常用What's it about?，about不可遗漏。 经典例题 ( ) —____ are you reading? —A story book about Ma Liang. A. What B. Where C. How 点拨 答案：A 【解析】句意：你正在读什么？一本关于马良的故事书。答语回答阅读的物品，用what提问事物；where问地点，how问方式，不符合题意。 小练笔 03 一、单项选择。 ( ) 1. —____ is this book about? —Animal eyes. A. What B. Who C. Where ( ) 2. ____ are you doing now? A. Who B. Where C. What ( ) 3. ____ book do you like best? A. What B. Where C. When ( ) 4. —____ is Mike reading? —A science book. A. How B. What C.

They reading books in the library. 10. I can draw pictures to remember poems. 现在进行时（询问正在做的事）高频易错点04 一、概念： 表示此刻正在发生的动作。 二、句型结构： 结构 例句 1. 肯定句：I am / You are / He is + doing I’m drawing pictures.（我正在画画。） 2. 一般疑问句：Am/Is/Are + 主语 + doing? Are you reading?(你正在读书吗？) 3. 特殊疑问句：What + am/is/are +主语 + doing? What are you reading?(你正读什么书？) 易错点提示 1.be动词和主语不匹配：I搭配am；you搭配are；he/she搭配is 2.忘记动词变ing形式 3.不要混用can、should和现在进行时结构。 经典例题 ( ) Look! Mike ____ a science book now. A. read B. reads C. is reading 点拨 答案：C 【解析】句意：看！Mike正在阅读科学书。look、now是现在进行时标志，需要用be+doing结构。 小练笔 04 一、单项选择。 ( ) 1. I ____ reading a story book. A. am B. is C. are ( ) 2.
