2. used to be quiet（过去很安静）
小练习（基础题+变式题）：

核心语法（教材Unit4-5重点，P35-P42语法板块）
（一）Unit4 语法：used to 与 be/get used to 辨析（必掌握）
简化规则：used to+do（过去的习惯，现在变）；be used to+名/doing（现在习惯，很稳定）；get used to+名/doing（逐渐适应，有过程）
易错点：
1. 混淆to的词性：used to中to是不定式符号，后接动词原形；be/get used to中to是介词，后接名/doing。
2. 忽略used to的否定/疑问结构：否定句用didn't use to，疑问句用Did...use to。
教材场景例句：
1. He used to be afraid of speaking in English class, but now he is used to expressing his ideas publicly.（教材P35-P36综合场景改编）
2. My sister is getting used to the new school because she has made many friends there.（教材P37主题场景例句）
小练习（基础题+变式题）： 基础题1：My brother ______ (play) computer games too much, but now he is used to ______ (read) books.
（答案：used to play；reading
易错原因：混淆to的用法，对应教材P35-P36语法辨析考点）
基础题2：—______ you ______ (walk) to school —Yes, but now I take the bus.

易错原因：疑问句结构错误，对应教材P35疑问句考点）
变式题1：She ______ (not be) used to ______ (eat) western food, but she is getting used to it now.
（答案：wasn't；eating
易错原因：be动词时态与to的搭配混淆，对应教材P36辨析考点）
变式题2：They ______ (get) used to ______ (study) online after the winter holiday.
（答案：got；studying
易错原因：get的时态误用为一般现在时，对应教材P36过程语义考点）
（二）Unit5 语法：被动语态（必掌握，教材P38-P42核心）
简化规则：被动语态=be动词+过去分词；时态看be动词，过去分词不变形；及物动词才能用，不及物动词无被动。
易错点：
1. 时态混淆：一般现在时用am/is/are，一般过去时用was/were，一般将来时用will be，现在完成时用have/has been。
2. 及物动词误用：如run、sleep等不及物动词不能用于被动语态。
3. 过去分词拼写错误：如forget的过去分词是forgotten，而非forgetted。
教材场景例句：
1. 一般现在时：English classes are held in the language lab every Wednesday.（教材P39原句改编：This kind of notebook is made of recycled paper）
2. 一般过去时：The school English competition was held last month.（教材P40原句改编：The school concert was held last Friday）
3. 一般将来时：The new English textbooks will be delivered to our school next week.（教材P41原句改编：The new classroom building will be completed next month）
4. 现在完成时：These English storybooks have been borrowed by many students in our class.（教材P42原句改编：These books have been borrowed by many students）
主动语态与被动语态转换（知识点）
转换规则：执行者与承受者互换位置，谓语动词变为“be+过去分词”，时态保持一致，by引出执行者（可省略）。
教材原句转换示例： 主动：Students in our class clean the classroom every day.（教材P39例句）
被动：The classroom is cleaned by students in our class every day.
小练习（基础题+变式题）： 基础题1：Teachers in our school correct our English homework carefully.（改为被动语态）
（答案：Our English homework is corrected carefully by teachers in our school.
易错原因：主语转换遗漏，对应教材P39转换考点）
基础题2：They held the school art festival last term.（改为被动语态）
（答案：The school art festival was held last term.
易错原因：一般过去时be动词误用为is，对应教材P40时态考点）
变式题1：We will finish the English group project before Friday.（改为被动语态）
（答案：The English group project will be finished by us before Friday.
易错原因：一般将来时结构错误，对应教材P41时态考点）
变式题2：She has translated many English articles into Chinese.（改为被动语态）
（答案：Many English articles have been translated into Chinese by her.
易错原因：现在完成时have/has的选择错误，对应教材P42时态考点）
三、综合练习
（一）词组运用题
1. 基础题：用used to、be used to或get used to的适当形式填空（对应教材P35-P36考点）
（1）My cousin ______ (not like) English, but now she is good at it.
（答案：didn't use to like 易错原因：否定句结构记忆不牢）

（答案：are used to having 易错原因：to后接动词原形错误）
（3）He ______ (live) in the countryside, so he is ______ (the quiet life) now.
（答案：used to live；getting used to 易错原因：混淆三种结构的语义）
2. 变式题：根据句意及教材词组提示完成句子（对应教材P37拓展考点）
（1）______ you ______ (play) the piano when you were a child
（答案：Did；use to play 易错原因：疑问句中used to还原错误）
（2）After half a year, the exchange student ______ (communicate) with us in Chinese.
（答案：got used to communicating 易错原因：get的时态与to的搭配错误）

1. 基础题：将下列主动语态改为被动语态（对应教材P39
P42考点）
（1）People use this kind of pen for writing English words.
（答案：This kind of pen is used for writing English words.
易错原因：一般现在时be动词选择错误）
（2）Our teacher taught us an English song yesterday.
（答案：An English song was taught to us by our teacher yesterday.

2. 变式题：选择正确的选项填空（对应教材易错点）
