Do you like dogs? does 主语 he /she/it 否定：doesn’t He doesn’t go to school. 疑问：Does...? Does she like music? did 所有人称（过去时） 否定：didn’t I didn’t watch TV. 疑问：Did...? Did you go there? do/does/did帮助实义动词变否定、疑问。 其他： 助动词 主要作用 例子 will / would 帮助构成将来时 I will go to school. have / has / had 帮助构成完成时 I have finished my homework. be (am/is/are) 帮助构成进行时和被动语态 He is reading. 注意： be动词既可以是助动词，也可以是系动词； have既可以是助动词，也可以是实义动词，需要根据用法判断。 四、情态动词 1.定义：表示语气、态度、能力、许可、意愿的词。自己不能单独作谓语，必须和实义动词原形一起用。 2.如何理解：情态动词是“动词小领导”，它站在动词前面，告诉别人这件事是“能”做、“可以”做、“必须”做还是“应该”做。 3.小学常见情态动词： 情态动词 意思 否定形式 用法 例句 can 能，会 can’t 表示能力、许可 I can swim. 我会游泳。 may 可以，也许 may not 表示请求、许可 May I come in? 我可以进来吗？ must 必须 mustn’t 表示必须、禁止 You must go to school. 你必须上学。 should 应该 shouldn’t 表示建议、应该 You should study hard. 你应该努力学习。 will 将要，愿意 won’t 表示将来、意愿 I will help you. 我会帮你。 注意：情态动词的用法 特征 说明 正确例句 错误例句 1. 后跟动词原形 情态动词+动词原形 I can swim.
