Can you + 动词短语（do sit-ups/jump rope...）? 解析：询问对方是否会做某项运动或技能的核心句型，can 为情态动词，后接动词短语原形，语气亲切，适用于课堂互动、日常交流场景。 2. No, I can't. But I can try. 解析：对应上面问句的否定回应，用 but 表转折，突出 “虽不会但愿意尝试”，呼应单元 “不放弃” 主题，是单元核心应答句型。 3. How many + 可数名词复数（sit-ups/times...）? + 数字（Ten/Twenty...）. 解析：询问运动次数或数量的句型，how many 后接可数名词复数，回答直接用数字，贴合 “尝试后计数进步” 的场景。 4. Try again./Don't give up!/Come on! 解析：鼓励型祈使句，“Try again.” 意为 “再试一次”，“Don't give up!” 意为 “别放弃”，“Come on!” 意为 “加油”，语气积极，是单元主题相关的核心鼓励句型。 5. Good job! 解析：赞扬他人做得好的句型，语气肯定，适用于他人完成任务或取得进步后，是日常交流中的礼貌赞扬表达。 核心语法 1. 情态动词 can 表 “能力” 的问答：Can you + 动词短语？肯定回答 “Yes, I can.”，否定回答 “No, I can't.”，否定后可接 but I can try. 表转折，体现 “尝试精神”。 2. how many 的用法：用于询问可数名词的数量，后接可数名词复数形式，回答用基数词（Ten/Twenty...），不可接不可数名词。 3. 祈使句的用法：Try again./Come on!/Have a try! 是肯定祈使句（动词原形开头），Don't give up! 是否定祈使句（Don't + 动词原形），用于发出鼓励或禁令，无主语，语气直接积极。 4. but 的转折用法：连接 “不会做” 和 “愿意尝试” 的前后分句，如 “I can't do sit-ups. But I can try.”，突出转折关系，呼应单元主题。 Part 03 Tips 考点01 “Can you...?” 及其回应 1.—Can you do sit-ups? 你会做仰卧起坐吗？ —No, I can't. But I can try. 不，我不会。但我可以试试。 2.—Can you jump rope? 你会跳绳吗？ —Yes, I can. 是的，我会。 3.—Can you play the erhu? 你会拉二胡吗？ —No, I can't. But I can try again. 不，我不会。但我可以再试试。 解析：本考点是单元核心，重点掌握 “询问能力 — 否定回应 — 转折尝试” 的固定表达。Can you 后接动词短语原形，否定回答必须用 “No, I can't.”，不可省略 can't；but 连接前后分句，强调 “虽无能力但有意愿尝试”，是单元主题的核心体现，也是高频考点。 一、单项选择。 ( ) 1. —Can you ________ rope? —No, but I can try. A. jump B. jumps C. jumping ( ) 2. —Can you do sit-ups? —________. But I can try again. A. Yes, I can B. No, I can't C. No, I don't ( )3. —Can you ________ the erhu? —Yes, I can.

But I can try. 2.—Can you swim? —________, ________ ________. But I can run fast. 3.—Can you play football? —No, I can't. ________ I can try. 提分练 Can you No I can’t But 考点02 “How many...?” 询问数量的用法 1.—How many sit-ups can you do? — 你能做多少个仰卧起坐？ —Twenty! 二十个！ 2.—How many times can you jump rope? — 你能跳绳多少下？ —Five! 五下！ 3.—How many balls do you have? — 你有多少个球？ —Ten! 十个！ 解析：本考点重点掌握 “how many + 可数名词复数” 的句型结构。 how many 用于询问可数名词的数量，后接复数名词（如 sit-ups/times/balls）， 回答直接用基数词（Ten/Twenty/Five），不可接不可数名词（如 water/milk），这是易错点。 一、单项选择。 ( ) 1. —How many ________ can you do? —Ten. A. sit-up B. sit-ups C. sit-upes ( ) 2. —How many times can you bounce the ball? —________. A. Twenty B. Yes C. No, I can't ( ) 3. —How many ________ do you see? —Five.

Come on! 试一试！加油！ 解析：本考点重点是祈使句的固定表达。 Try again.（再试一次） Don't give up!（别放弃） Have a try!（试一试） Come on!（加油）均为鼓励他人的祈使句，无主语，动词原形开头（Don't 后接动词原形）。 一、单项选择。 ( ) 1. —I can't do it. —________! Try again. A. Give up B. Don't give up C. Can't give up ( )2. —It's hard. —________a try! You can do it. A. Have B. Has C. Having ( )3. —Come on! ________ again! —OK! I can do it now. A. Try B. Tries C.
