Should / Shouldn't 表示建议/劝告: You should be polite to others. 你应该对他人有礼貌。 We shouldn't make too much noise. 我们不应该制造太多噪音。 2. 询问规则: — What are the rules? 规则是什么? — We have to be quiet in the library. 我们在图书馆必须保持安静。 — Can I listen to music here? 我可以在这里听音乐吗? — Yes, you can. / No, you can't. 可以。/ 不可以。 — Do we have to wear a uniform? 我们必须穿校服吗? — Yes, we do. / No, we don't. 是的,必须。/ 不,不必。 3. 讨论规则与陈述理由: I think this rule is important because it keeps us safe. 我认为这条规则很重要,因为它能保证我们的安全。 I agree. We should follow the rules. 我同意。我们应该遵守规则。 I don't agree. I think we can use phones sometimes. 我不同意。我觉得我们有时候可以用手机。 What do you think of the rule? 你觉得这条规则怎么样? 4. 理解与书写规则(常见于标志/通知): No talking! 禁止交谈! Keep quiet. 保持安静。 Don't eat or drink here. 请勿在此饮食。 Please turn off your phone. 请关闭手机。 三、 核心语法精讲 【重点1】情态动词 Must, Have to, Can 的用法辨析 1. Must 与 Have to: Must 强调主观看法、义务或命令,语气最强。 否定形式 mustn't 表示“禁止”。 I must study hard. (我认为我必须努力。) You mustn't smoke here. (此处严禁吸烟。) Have to强调客观需要、规定或要求(如校规、法律)。 否定形式don't/doesn't have to 表示“不必”,相当于 needn't。 We have to wear seat belts in the car. (法规要求我们必须系安全带。) You don't have to come tomorrow. (你明天不必来。) 2. Can 与 Can't: Can 表示“被允许、可以”,语气较 may 更随意。Can I...? 常用于口语请求许可。 Can't 表示“不允许、不可以”,语气较 mustn't 稍弱。 中考易错点:mustn't (禁止) ≠ don't have to (不必)。 You mustn't go. (你不许去。) You don't have to go. (你不必去。) 【重点2】祈使句 用于表达命令、请求、劝告或建议,常见于规则标志。 1. 肯定祈使句:动词原形 开头。 Be quiet. Listen carefully. Keep your desk clean. 2. 否定祈使句:Don't + 动词原形。 Don't run. Don't be late. Don't eat in class. 3. 以Let's开头的祈使句:表示建议。 Let's follow the rules. Let's not fight. 四、 中考能力拓展与易错点提示 1. 情态动词后的动词形式: 所有情态动词 (must, can, should, have to等) 后面都必须跟动词原形。 He must finishes his work. ( ) He must finish his work. (√) 2. Have to 的疑问与否定:需借助助动词 do/does。 Does she have to go? We don't have to stay. 3. “遵守/违反规则”的搭配: follow/keep/obey the rules (遵守规则);break the rules (违反规则)。 4. 讨论规则时的逻辑连接词: 陈述理由:because, so that 表达观点:I think..., In my opinion... 表示转折:but, however 1 学科网(北京)股份有限公司 $
