语法专项第2次课-动词（课件）湘少版（三起）英语六年级下册

动词 V. 回顾： 名词是什么？ 单数变复数规则有哪些？ 动词 动词是表示动作和状态的词，有人称和数的变化 其中包括 be动词、情态动词、助动词 如：run,jump,swim，sing...... ？Be动词有几个？ am,is,are 用法？ am:第一人称 is：第三人称单数和所有单数 are：第二人称和复数 注意：was/were 口诀：我用am, 你用are, is用在他她它，单数is复数are I ____ she_____ he____ you____ they____ Jenny_____ Lily_____ my father_____ the old man_____ my friends______ it_____ am is is are are is is is is are is 学生自由发挥造句 完成书上21页第一题 改为否定句： be动词的否定形式： am not（没有缩写形式）， are not = aren’t ， is not = isn’t 。 在Be动词后 + not I am a teacher. I am not a teacher. He is a driver. He is not/isn't a driver. 一般疑问句 1.Be动词提前 2.my改为your,I 改为 you，am 改为 are 3.符号，大小写 I am a teacher. Are you a teacher? 按要求完成句子 I am a policeman.(改为否定句) He is a humorous man.(改为一般疑问句) They are good firends.(改为一般疑问句) Lily is my sister.(改为否定句) I am not a policeman. Is he a humorous man? Are they good friends? Lily is not / isn't my sister. 翻译下列句子 Do you know? I don't know. We don't have class next week. Do 是什么意思？ Do 没有实际意义 助动词 特点： 1. 本身没有词义，不能单独作谓语，只能和别的动词一起构成谓语; 2. 表示时态、语态、语气等特征; 3. 帮助构成否定、疑问、强调、省略等。 主要的助动词有 do（do,does,did）, have（have,has,had）, shall, will 等 分类 作 用 do 形式有do, does, did 用于构成疑问句和否定句，或用在动词前加强语气。 will / shall will / shall + 动词原形→一般将来时 would /should + 动词原形→过去将来时 观察 She doesn't like the dress. He didn't go to park yesterday. I didn't go to school yesterday. They don't like the cat. I don't know. You don't say the truth. does:第三人称单数 did:过去时 do:其他（第一人称；第二人称，复数） 用适当的助动词填空 1. ______you like this magazine?       2.
