区别于 be used to doing (习惯于做) 和 be used to do (被用来做)。疑问句 Did you use to...?

无被动语态,不能说 be taken place。指计划好的事情发生。
in the past few years

progress是不可数名词,不能说 make a progress。
keep in touch with
与……保持联系
同义短语:stay in contact with。
succeed in doing sth.
成功做某事
succeed是动词,success是名词,successful是形容词。
thanks to
多亏;由于
后接名词词或代词,通常引出积极结果。
so far
到目前为止
常与现在完成时连用。
be/get used to doing

三、核心语法突破:描述变化
本单元语法核心在于如何准确描述“过去”与“现在”的对比,主要涉及 Used to 结构和 现在完成时 的综合运用。
1. Used to 结构回顾
· 肯定句: Subject + used to + verb (原形).
· Ex: I used to be short, but now I am tall.
· 否定句: Subject + didn't use to + verb (原形) / Subject + used not to + verb (原形).
· Ex: He didn't use to like math.
· 一般疑问句: Did + subject + use to + verb (原形)?
· Ex: Did you use to walk to school?
· 【易错警示】
· 区分 used to do (过去常做), be used to doing (习惯于做), be used to do (被用来做)。
· 口诀: used to do 过去常,be used to doing 习惯忙,be used to do 被用场。
2. 现在完成时 (Present Perfect Tense) 在描述变化中的应用
· 结构: have/has + past participle (过去分词)
· 用法: 表示过去发生的动作对现在造成的影响,或从过去持续到现在的状态。常与 in the past few years, so far, since, for 连用。
· ★中考高频考点:
· 延续性动词转换: 当与 for/since 连用时,瞬间动词需转换为延续性动词。
· buy -> have
· borrow -> keep
· join -> be in / be a member of
· die -> be dead
· begin/start -> be on
· Ex: He joined the club two years ago. -> He has been in the club for two years. (√)
· Ex: He has joined the club for two years. (×)
3. 被动语态 (Passive Voice) 简述
· 在描述社会变化、科技发明时常用。
· 结构: be + past participle
· Ex: Many new buildings have been built in our city. (我市已经建起了许多新大楼。)
四、经典句型与写作素材
1. 功能话题句型
· 描述过去的状态:
· People used to live in small and dark houses.
· In the past, there were no high-speed trains.
· 描述现在的状态及变化:
· Now, people live in tall buildings with bright rooms.
· Great changes have taken place in my hometown.
· Thanks to the reform and opening-up policy, our life is getting better and better.
· 表达感受:
· I am proud of the rapid development of my country.
· It is convenient for us to travel around because of the high-speed railway.
2. 写作模板:Changes in My Hometown
Title: Changes in My Hometown
My hometown has changed a lot in the past few years.
In the past, the roads were narrow and dirty. People lived in old houses. They used to walk or ride bikes to work. Communication was not convenient, so they seldom kept in touch with friends far away.
However, great changes have taken place now. The roads are wide and clean. Tall buildings can be seen everywhere. Many families have their own cars. It is easy for us to communicate with others by mobile phones or the Internet.
Thanks to the hard work of the people and the development of society, our life is becoming more and more beautiful. I love my hometown and I hope it will be better in the future.
【写作要点提示】
1. 时态切换: 描写过去用一般过去时 (used to, was/were),描写现在用一般现在时或现在完成时 (has/have done, is/are)。
2. 连接词: 使用 However, But, So, Thanks to 等使文章逻辑连贯。
3. 对比手法: 从交通、居住、通讯、环境等方面进行今昔对比。
五、课堂实战演练
I. 情景对话 (Communicative Dialogue)
根据对话内容,从方框中选择适当的句子补全对话,其中有一项是多余的。
A: Hi, Li Hua! Long time no see. You look different. B: Really? 1 A: You used to be short and thin, but now you are tall and strong. B: Yes, I play basketball every day. 2 A: That's a good habit. By the way, how is your hometown? B: 3 There are many new parks and libraries. A: Sounds great! How do people usually go to work now? B: 4 It's fast and convenient. A: 5 B: Yes, I think so. Our life is getting better and better.
A. It has changed a lot.
B. What has changed?
C. Do you like living here?
D. They usually drive cars or take the subway.
E. I used to be weak, but now I am healthy.
F. Where did you go?
【答案】
1. B 2. E 3. A 4. D 5. C
【解析】
1. 选B。 上文说“You look different”,下文具体描述了外貌变化,故问“什么变了?”。
2. 选E。 上文提到打篮球,此处应承接说明身体变得健康强壮,与used to形成对比。
3. 选A。 问家乡如何,回答“变化很大”,后文列举了新公园和图书馆作为佐证。
4. 选D。 问现在人们怎么上班,回答具体的交通方式(开车或地铁)。
5. 选C。 下文回答“Yes, I think so.”且提到生活变好,故推测问句为一般疑问句,询问是否喜欢住在这里。F项多余。
II. 文化常识选择 (Cultural Awareness)
本题考察中英文交际差异及文化背景知识。
6. When a Chinese friend says "Have you eaten?" (你吃了吗?), what does he/she usually mean? A. He wants to invite you to dinner. B. He is asking about your health condition. C. It is a common greeting, similar to "How are you?". D. He thinks you look hungry.
7. In Western countries, if someone praises you by saying "You speak English very well!", how should you usually respond? A. No, no, my English is poor. B. Thank you. C. I don't think so. D. You are joking.
【答案】 6. C 7. B
【解析】 6. 选C。 在中国文化中,“吃了吗”常作为一种非正式的问候语(Greeting),并不一定真的关心对方是否进食或邀请吃饭,类似于西方的"How are you?"。这体现了中西方交际文化的差异。 7. 选B。 在西方文化中,面对赞美(Praise),通常直接接受并表示感谢(Thank you),以示自信和礼貌。而中式思维中常倾向于谦虚否认(No, no...),这在跨文化交际中需注意避免误解。
III. 单项选择 (Multiple Choice)
8. — Look! The river is much cleaner than before. — Yes. Great changes ______ in our city since last year. A. took place B. have taken place C. were taken place D. have been taken place

12. — I find it hard to communicate with my parents. — Why not try ______ to them? They love you. A. talk B. talking C. to talk D. talked
【答案】 8. B 9. B 10. C 11. C 12. B
【解析】 8. 选B。 关键词 since last year 暗示使用现在完成时。take place 是不及物动词短语,没有被动语态,排除C、D。A为一般过去时,不符语境。故选B。 9. 选B。 句意:“爷爷过去抽烟,但现在戒了。” used to do 表示过去常常做某事,现在不做了。be used to doing 表示习惯于。故选B。 10. 选C。 rapid 是形容词,修饰名词。develop 是动词,development 是名词。句意:“随着科技的快速发展……”。故选C。 11. 选C。 关键词 For two weeks 表示一段时间,谓语动词必须是延续性动词。borrow, lend, buy 均为瞬间动词,不能与时间段连用。keep 是延续性动词。故选C。 12. 选B。 try doing sth. 意为“尝试做某事(看效果如何)”;try to do sth. 意为“尽力做某事”。此处建议尝试“沟通”这种方式,故用 talking。故选B。
IV. 完成句子 (Complete the Sentences)
13. 过去我害怕在公共场合说话,但现在我很自信。 I __________ __________ __________ afraid of speaking in public, but now I am confident.
