B 💡 句式：过去进行时 + when + 一般过去时。'正在街上走，突然遇到了老朋友'。when从句用短暂动作met。 2. A 💡 while连接两个同时进行的过去进行时。B的when后接延续性动作slept不自然；C的while后接短暂动作rang错误；D的meet是短暂动作不能用while。 3. A 💡 when引导的过去时间，主句用过去进行时表示当时正在持续的动作。风在吹、雨在下，两个延续动作同时进行。 【拓展题答案】 1. B 💡 句式：过去进行时 + when + 一般过去时。'正在读小说，灯突然灭了'。go out是短暂动作，用一般过去时went。 2. A 💡 fall off是短暂动作（过去时fell off），ride是延续动作（过去进行时was riding）。'正在骑车时摔了下来'。 3. B 💡 根据前句wasn't listening（过去进行时），后句也用过去进行时was helping。in the kitchen是固定搭配。 📌 考点4：情态动词 must/have to/should/mustn't 辨析（主观vs客观/禁止vs不必） 【基础题答案】 1. B 💡 must表'必须'，强调法律/规则要求。骑自行车戴头盔是法律规定，用must语气最强。 2. C 💡 must问句的否定回答用needn't（不必）或don't have to。mustn't表示'禁止'，不能用于否定回答。 3. C 💡 mustn't表'禁止/绝对不要'。在厨房玩火很危险，用mustn't表示严禁。 【提升题答案】 1. B 💡 have to表客观需要'不得不'。must没有过去式，表达过去的'必须'用had to。 2. B 💡 must表有把握的肯定推测'一定'。灯亮着→她一定在学习。can't表否定推测'不可能'。 3. C 💡 mustn't表'禁止'。带危险物品到学校是严格禁止的，语气最强。shouldn't只是'不应该'，力度不够。 【拓展题答案】 1. C 💡 第一空：had to（过去客观需要）因为发烧不得不卧床。第二空：doesn't have to（不必）如果感觉好些就不必去学校。 2. B 💡 Need I...?的肯定回答用Yes, you must. 否定回答用needn't。此处医生要来，必须留下，用must。 3. B 💡 第一空：had to（过去客观被迫）因为搭档生病。第二空：didn't have to worry（过去不必担心）因为老师帮忙了。 📌 考点5：if 条件状语从句（主将从现 / 主句用祈使句或情态动词） 【基础题答案】 1. A 💡 if引导条件状语从句，主句用一般将来时will stay，从句用一般现在时rains（主将从现）。 2. B 💡 主句是祈使句stay calm，if从句用一般现在时see（主将从现的变体）。 3. A 💡 unless = if...not（除非=如果不）。主句can't go是情态动词，unless从句用一般现在时finish。 【提升题答案】 1. B 💡 if从句用一般现在时practices，主句用一般将来时will win（主将从现）。 2. C 💡 if从句不能用将来时will come，要用一般现在时comes。C错误。 3. A 💡 unless = if...not。主句won't go是将来时，unless从句用一般现在时receives（主将从现）。 【拓展题答案】 1. A 💡 if从句用一般现在时tries，主句用一般将来时will be（主将从现）。be proud of是固定搭配。 2. A 💡 unless从句用一般现在时gets，主句用一般将来时will be put off（被动语态）。主将从现原则。 3. A 💡 if从句用spend（一般现在时），主句用will find it hard（一般将来时）。find it + adj. + to do结构。 📌 考点6：现在完成时 have/has been to vs have/has gone to（时间标志+辨析） 【基础题答案】 1. A 💡 ever用于现在完成时Have you been to（去过已回）。in 2023是具体过去时间，用一般过去时went。 2. B 💡 has gone to去了某地（人未返回）。根据'他不在'，说明人还在图书馆，用gone。 3. B 💡 Olivia第三人称单数用has。现在完成时结构：has + 过去分词。ride的过去分词是ridden。 【提升题答案】 1. D 💡 for five years是延续性时间状语，用现在完成时。The Zhang family指一家人（复数），用have lived。 2. A 💡 How many times问次数，用have/has been to。Lily第三人称单数用has been。 3. A 💡 just常和现在完成时连用。Jam第三人称单数用has finished。so he can lend it说明已经读完了。 【拓展题答案】 1. B 💡 since引导的时间状语，主句用现在完成时。两个并列动作都用have made和have learned。 2. A 💡 twice提示现在完成时has seen（经历）。a third time表示'再一次/第三次'（不特指用a）。 3. A 💡 ever用于现在完成时疑问句：Have/Has + 主语 + 过去分词？experience的过去分词是experienced。 📌 考点7：It's + adj. + to do 句型 & 动词不定式 to do 的用法 【基础题答案】 1. A 💡 It's + adj. + to do 句型。It作形式主语，真正主语是不定式to exercise。 2. B 💡 want to do sth. 想要做某事。want后接不定式作宾语。 3. B 💡 tell sb. to do sth. 告诉某人做某事。不定式作宾补。 【提升题答案】 1. B 💡 It's + adj. + to do 句型。It是形式主语，真正主语是to play with fire。 2. A 💡 let/make/have/see/hear等使役/感官动词后接不带to的不定式（动词原形）。let sb. do sth. 3. C 💡 It's a good idea to do sth. 做某事是个好主意。不定式to keep作真正主语。 【拓展题答案】 1. A 💡 第一空：To stay是不定式作目的状语；第二空：avoid doing sth. 避免做某事，avoid后接动名词。 2. A 💡 第一空：疑问词how + to do（how to use）；第二空：make mistakes to do为不定式表目的。 3. B 💡 decide to do sth. 决定做某事；advise sb. to do sth. 建议某人做某事。两个都是带to的不定式。 📌 考点8：when 与 while 的区别（短暂vs延续 + 句式搭配） 【基础题答案】 1. B 💡 walk是延续性动作，用while引导（while后接延续性动作）。'在走回家的过程中，看到了车祸'。 2. B 💡 句式：过去进行时 + when + 一般过去时。ring是短暂动作，用一般过去时rang。 3. D 💡 although/though引导让步状语从句，'虽然雨下得很大，但他仍然按时到校'。while不能表让步。 【提升题答案】 1. C 💡 while后接的从句动作必须是延续性的。when后接的动作可以是短暂或延续性的。两者不完全可互换。 2. B 💡 两个同时进行的延续性动作，用while连接。主句和从句都用过去进行时。 3. C 💡 be about to do...when... 正要做某事，这时（突然）……。when在此表示'这时'，不能用while替代。 【拓展题答案】 1. C 💡 take...seriously是延续性动作（过去进行时were taking），tell是短暂动作（一般过去时told）。when连接两个动作。 2. D 💡 fall asleep是延续性动作，as/when/while都可以引导延续性动作的从句。三个都对。 3. C 💡 break是短暂动作（过去时broke），play是延续动作（过去进行时was playing）。while后接延续性动作。 📌 考点9：反身代词的构成与固定搭配（enjoy/by/help/protect...oneself） 【基础题答案】 1. B 💡 enjoy oneself 玩得开心。children对应反身代词themselves（复数）。 2. C 💡 by oneself 独自/亲自。Olivia是女性，用herself。 3. D 💡 protect oneself 保护自己。students是复数，对应反身代词themselves。 【提升题答案】 1. C 💡 help oneself to 随便吃/取。对一个人说用yourself。 2. B 💡 teach oneself 自学。Zhou Kai对应himself。 3. C 💡 dress oneself 给自己穿衣服。the little girl对应herself。 【拓展题答案】 1. B 💡 by oneself 独自。I对应myself。 2. C 💡 反身代词作同位语加强语气。the students对应themselves。 3. D 💡 look at oneself in the mirror 照镜子。Bella是女性，用herself。 📌 考点10：There's no need to / What if / I wonder if / 感叹句 / 易混搭配 【基础题答案】 1. C 💡 感叹句：有名用what，无名用how。amazing是形容词，前无名词，用How。How + adj. + 主谓! 2. A 💡 There's no need to do 没必要做某事。安慰对方'没必要紧张，你已经准备得很好了'。 3. B 💡 experience此处为可数名词单数'一次经历'，用What a + adj. + 单数名词 + 主谓! 【提升题答案】 1. C 💡 What if...? 要是……怎么办？表达担忧。'要是运动会期间下雨怎么办？' 2. B 💡 I wonder if... 委婉表达对他人情绪的猜测。if=whether，不能用that。'我想知道他是否还在生我的气'。 3. D 💡 No matter how + adj./adv. + 主谓，主句... 无论多么……。how修饰形容词hard。 【拓展题答案】 1. A 💡 It seems that... 根据观察推测'似乎……'。today提示现在时，用is。 2. B 💡 All I want is to do 我唯一想要的是……。understand与I之间是被动关系（被理解），用to be understood。 3.
