Unit 1 The Changing World Section A (4a–4c) · 语法聚焦:一般过去时、现在完成时与 used to (讲义 · 学生用) 课时基本信息 课题 Unit 1 The Changing World Section A(4a–4c) 课型 语法·语言运用课(时态辨析与语法操练) 年级 九年级上册 课时 第 3 课时(对应教材 Section A 4a–4c / Grammar Focus) 教材 人教版(2024)九年级上册 Unit 1 The Changing World Section A(4a–4c),课本第 5 页 主题 一般过去时、现在完成时与 used to 的辨析;语法填空与综合选择;as well as / make it + adj. / wide 等核心短语 教学重难点 重点 掌握一般过去时、现在完成时与 used to do 三种核心结构的形式、含义及时间标志词; 能在语境中正确判断并运用三种时态完成 4a 圈动词、4b 补全对话、4c 语篇填空及综合选择; 掌握 as well as、make it + adj. + for sb. + to do sth.、wide/widely/width 等重点短语与词汇。 难点 准确区分一般过去时(过去已结束)与现在完成时(过去关联现在)的语义边界; 区分 used to do(过去常做/状态,现在不)与 be used to doing(习惯于)/ be used to do(被用来做); 在语篇填空中兼顾上下文逻辑与动词时态、语态、非谓语形式的综合判断。 (一)Grammar Focus:圈出动词,判断时态(课本 p.5) 读 Grammar Focus 中的六个句子,圈出谓语动词,并判断其时态。 图 1 4a:读句子、圈动词、关注时态 句子 谓语动词/结构 时态 He became a good friend of your grandfather about 20 years ago. became 一般过去时 They haven't seen each other for ages! haven't seen 现在完成时 We used to have to travel far to see a doctor. used to have used to(过去习惯/状态) Our village has just built a new hospital. has built 现在完成时 Many people used to work in big cities. used to work used to Now, more of them have come back to live and work here. have come back 现在完成时 【提示框】判断时态先看时间标志词:ago / last year / yesterday → 一般过去时;already / yet / just / since / for → 现在完成时;used to → 过去常做或状态。 (二)一般过去时:表示过去发生的动作或状态 基本含义:表示过去某个时间发生的动作或存在的状态,与现在没有联系。 时间标志:yesterday, last week/month/year, … ago, just now, in 2020, at that time, once 等。 构成:动词用过去式(work → worked;study → studied;go → went;be → was/were)。 否定/疑问:Did + 主语 + 动词原形? / 主语 + didn't + 动词原形。例:Did he go? He didn't go. (三)现在完成时:过去与现在的关联 基本含义:表示过去发生的动作持续到现在,或过去动作对现在造成影响、结果。 时间标志:already, yet, just, ever, never, since, for, so far, in the past few years, recently 等。 构成:have/has + 过去分词(I have finished; She has gone)。 与一般过去时的区别:一般过去时只谈过去;现在完成时强调“过去→现在”。 例:He lived here for ten years.(曾住过,现在不在)/ He has lived here for ten years.(住了十年,现在仍住) (四)used to do:过去常常或过去的状态 基本含义:表示过去常常做某事,或过去存在某种状态,现在已不再是那样。 构成:used to + 动词原形。否定 didn't use to / used not to;疑问 Did … use to …? 例句:My father used to smoke, but now he doesn't smoke at all. 易混辨析:used to do(过去常做)/ be used to doing(习惯于做)/ be used to do(被用来做)。 【易混点】used to 只用于过去;be used to doing 表示习惯,to 是介词;be used to do 表示用途,to 是不定式符号。 (五)4b:用动词正确形式补全对话(课本 p.5) 根据上下文和时态提示,在空格中填入括号内动词的正确形式。 图 2 4b 对话填空 空格 参考答案 1. ___ you ___ (be) to the new library yet? Have; been(现在完成时 + yet) 2. No, I ___ (not know) there was a new library. didn't know(一般过去时) 3. When did it ___ (open)? open(助动词 did 后用原形) 4. It ___ (open) last Friday. opened(last Friday 一般过去时) 5.

I ___ (bring) my little brother there tomorrow. will bring(tomorrow 一般将来时) (六)4c:用动词正确形式补全短文(课本 p.5) 阅读关于贵州交通变化的短文,用括号内动词的正确形式填空。 图 3 4c 语篇填空 空格 参考答案 1. In the past, it ___ (be) difficult to travel in Guizhou. was(一般过去时) 2. there used to ___ (be) no bridges be(used to 后接动词原形) 3. This ___ (make) it difficult for locals made(一般过去时) 4.

They are much richer and happier than they once ___ (be). were(once 一般过去时) (七)综合选择:辨析时态与 used to 选出最佳答案,并说明判断依据。 题号 题目与选项 答案与依据 1 —Where is your brother? —He ______ to the library ten minutes ago. A. goes B. went C. has gone D. used to go B。ten minutes ago 是一般过去时标志。 2 My father ______ smoke, but now he doesn't smoke at all. A. used to B. is used to C. was used to D. uses to A。but now 暗示过去常做、现在不,用 used to。 3 I ______ this movie twice. It's really wonderful.

A. lived B. has lived C. used to live D. lives B。for three years 且 still lives here now 用现在完成时。 (八)核心短语与词汇(课本 p.5) 本课时重点短语与词汇。 图 4 重点短语 as well as 图 5 重点结构 make it + adj. + for sb. + to do as well as 除……之外,也,还(连接并列成分,强调前者)。例:He speaks English as well as French. make it + adj. + for sb. + to do sth. 使做某事对某人来说……。it 是形式宾语,真正宾语是后面的 to do。 例:The new railway makes it easier for local people to travel. (新铁路让当地人出行更便捷。) wide /waɪd/ adj. 宽的;宽阔的。widely adv. 广泛地;普遍地。width n. 宽度。 例:The new road is very wide. / English is widely used all over the world. 【易混点】as well as 强调前面内容;not only … but also … 强调后面内容。wide(adv.)侧重具体空间“张得大”;widely 侧重抽象“广泛地”。 易错提醒 ① 一般过去时只描述过去已发生的动作/状态,与现在无关;现在完成时强调“过去→现在”的关联。 ② used to 后接动词原形;否定/疑问借助 did:Did you use to …? / I didn't use to … ③ 看到 already / yet / just / ever / never / since / for / in the past few years 优先考虑现在完成时。 ④ make it + adj. + for sb. + to do 中 it 不能换为 this/that;形容词描述“事情”本身时用 for,描述“人”的品质时用 of。 答题技巧 ① 圈动词题:先找时间标志词,再判断时态,最后核对主谓一致。 ② 对话填空:根据上下文的 already / yet / last Friday / tomorrow 等标志锁定时态。 ③ 语篇填空:通读全文把握“过去困难—现在变化”的对比结构,按时间线切换时态。 ④ 综合选择:先排除明显时态不符的选项,再用时间状语和上下文验证剩余选项。 语言点归纳 ● 一般过去时:动词用过去式;常与 ago / last … / yesterday / in 2020 / once 连用。 ● 现在完成时:have/has + 过去分词;强调过去动作对现在的影响或从过去持续到现在。 ● used to do:过去常做/状态(现在不);否定 didn't use to;疑问 Did … use to …? ● 重点结构:as well as; make it + adj. + for sb. + to do sth.; wide / widely / width。 课堂总结 本课时聚焦三种核心时态:一般过去时、现在完成时与 used to do; 通过 4a 圈动词、4b 补全对话、4c 语篇填空与综合选择,练习了根据时间标志和语境选择正确时态; 学习了 as well as、make it + adj. + for sb. + to do sth.、wide/widely/width 等重点短语与词汇。 学科网(北京)股份有限公司 $
