Should I call the doctor 特殊疑问句 疑问词 + should + 主语 + 动词原形? What should I do next 四、易错点突破1、与must混淆should:建议/义务(非强制)must:强制要求 You must eat vegetables.(强制)→ You should eat vegetables.(建议)2、should后加to You should to study harder. → You should study harder.3、should have done(过去本该做) You should finish it yesterday. → You should have finished it yesterday.4、should表推测时 He should is at home now. → He should be at home now.五、特殊用法1、"Had better"对比should:一般建议had better:强烈建议(隐含警告) You should exercise.(建议) You had better hurry, or you'll miss the bus.(警告)2、虚拟语气中It's strange that he should say that.(竟然)3、委婉请求Should I open the window (比Shall I更正式)六、记忆口诀"should表建议和义务,后接动词原形记清楚。否定就用shouldn't,疑问句首提前出。推测责备特殊用,比must语气更婉转!"1.—I don’t care what Kate thinks.—Well, you _______.
