Unit 1 The Changing World Section A (4a–4c) · 时态综合运用与语言点 (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·语用综合课(时态辨析与语言点运用) 年级 九年级上册 课时 第 4 课时(对应教材 Section A 4a–4c) 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 家乡交通与生活的今昔变化;时态综合运用;yet/already 与 make it + adj. + to do 教学重难点 重点 读懂 4b 对话与 4c 短文,准确运用四种时态描述今昔变化:现在完成时(have/has + done)、一般过去时、used to do、一般将来时(will); 掌握 yet 与 already 的区别与位置;掌握 make it + adj. + (for sb) + to do 结构; 掌握本课时核心词汇:digital, audio, dirt, track, wide, tunnel, course。 难点 在语篇中准确判断并运用四种时态,避免混用(尤其现在完成时与一般过去时); yet 用于疑/否句末、already 用于肯定句(疑问句表意外)的位置与语用区别; make it + adj. + to do 中 it 是形式宾语,真正宾语是不定式,易误写成 make sb + 原形。 (一)Warm-up:说说你家乡的大变化(课本 p.5) 看图思考并回答:你喜欢你的城镇吗?过去 10 年你见证了哪些大变化?(课本 p.5 导入) A: Do you like your town? — Yes, I do. It's becoming more and more beautiful. B: What big changes have you seen in your town over the past 10 years? — The subway opened and the old market was rebuilt into a shopping mall. 【过渡语】用现在完成时(have seen / has opened)说“过去发生、与现在相关”的变化,自然引出 4a–4c 的时态综合运用。 (二)核心新词(课本 p.5) 熟读下列新词,注意音标与词性(课本 p.5 词汇表)。 course /kɔːs/ int./adv. 当然(常用于 Of course) digital /ˈdɪdʒɪtl/ adj. 电子的;数字的 audio /ˈɔːdiəʊ/ adj. 音频的 n. 音频 dirt /dɜːt/ n. 泥土;尘土 track /træk/ n. 小路;轨道 wide /waɪd/ adj. 宽的;宽阔的 tunnel /ˈtʌnl/ n. 隧道;地下通道(以上均课本 p.5) 【提示框】track 作“小路”是可数(dirt tracks),作“轨道”也常用复数(railway tracks)。tunnel 可数,复数为 tunnels。digital books = 电子书,audio books = 有声书。 (三)4a:圈出动词,关注时态(课本 p.5) 读课文中的句子,圈出动词并判断时态(课本 p.5 活动 4a)。下列来自 4b、4c 的句子可供练习: ① Have you been to the new library yet? → been(现在完成时) ② I didn't know there was a new library. → didn't know / was(一般过去时) ③ It opened last Friday. → opened(一般过去时) ④ There used to be no bridges. → used to be(过去常有的状态) ⑤ Great changes have taken place. → have taken(现在完成时) ⑥ A journey that used to take a day now takes only a few hours. → used to take(过去)/ takes(一般现在时) 【知识点】圈动词时先找时间信号:yet / in the past few years → 现在完成时;last Friday / in the past → 一般过去时;used to → 过去状态;now / today → 现在/将来。 (四)4b:用动词适当形式补全对话(课本 p.5) 读对话,用括号内动词的正确形式填空(课本 p.5 活动 4b)。 A: Have you been to the new library yet? B: No, I didn't know there was a new library. When did it open? A: It opened last Friday. I went there with my grandpa on Saturday night. B: Do you like it? A: Of course! It's the most high-tech library I have ever visited. B: Oh, what did you see there? A: There are sections with books about science and Chinese culture, as well as a huge section with children's books. I also read some digital books on the computer. My grandpa listened to some audio books because he can't see well. B: Cool! I will bring my little brother there tomorrow. 【提示框】时态混合:yet→现在完成时(have been);last Friday→一般过去时(opened/went);ever→现在完成时(have visited);tomorrow→一般将来时(will bring)。 (五)语言点:yet 与 already(课本 p.5) 例句:Have you been to the new library yet?(你去过新图书馆了吗?) ① yet 意为“已经;仍然;还”,用于句末,多用于疑问句或否定句:疑问句中“已经”,否定句中“还”。 例:Have you cleaned your room yet? 你打扫房间了吗? 例:They haven't come back from school yet. 他们还没从学校回来。 ② already 意为“已经,早已”,多用于肯定句;用于疑问句时表示“惊奇/意外”。 例:I have already finished my homework. 我已经完成作业了。 【提示框】位置口诀:yet 常在句末(疑/否);already 常在句中(肯定)。got it? → 疑问用 yet,陈述用 already。 小试:1. I haven't finished my homework ______. A. already B. yet C. ever D. just (答案:B) 2. Have you visited the museum ______? A. yet B. already C. still D. never (答案:A) (六)4c:用动词适当形式补全短文(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(课本 p.5 活动 4c)。 In the past, it was difficult to travel in Guizhou. In many places, there used to be no bridges to cross mountains and rivers, and most roads were just dirt tracks. This made it difficult for locals to bring products to the market or to develop industry. Now great changes have taken place. The government has built thousands of kilometres of highways, railways, and wide roads. It has also built many high bridges and tunnels. A journey that used to take a day now takes only a few hours. As a result, the lives of local people have improved. They are much richer and happier than they once were. 【知识点】短文交织四种时态:was / were / used to be / made(过去);have taken place / has built / have improved(现在完成时);used to take(过去习惯);takes(现在)。抓住信号词即可填对。 (七)语言点:make it + adj. + (for sb) + to do(课本 p.5) 例句:This made it difficult for locals to bring products to the market or to develop industry. 结构:make + it(形式宾语)+ 形容词 + (for sb) + 不定式(真正宾语)。 it 是“替身”,后面的不定式才是真正的宾语。 例:She finds it relaxing to listen to music after school. 她觉得放学后听音乐很放松。 例:I think it important to protect the environment. 我认为保护环境很重要。 【提示框】类似用 it 作形式宾语的动词还有 find / think / feel 等;真正宾语是不定式,不能写成 make it difficult bring。 小试:1. The new rules make it ______ for us ______ English well. A. easy; learn B. easy; to learn C. easily; learn D. easily; to learn (答案:B) 2. The Internet makes it easy ________ (talk) with friends far away. (答案:to talk) (八)核心词汇与句型(课本 p.5) 本课时重点词汇与表达,音标以课本新词表为标准,统一标注页码「课本 p.5」。 核心词汇 course /kɔːs/ int./adv. 当然(Of course) digital /ˈdɪdʒɪtl/ adj. 电子的;数字的 audio /ˈɔːdiəʊ/ adj. 音频的 n. 音频 dirt /dɜːt/ n. 泥土;尘土 track /træk/ n. 小路;轨道 wide /waɪd/ adj. 宽的;宽阔的(以上均课本 p.5) tunnel /ˈtʌnl/ n. 隧道;地下通道(课本 p.5) 【提示框】tunnel 由 tunn(el) + el 构成;railway / highway / tunnel 都是交通类名词,常一起出现描述交通建设。dirt track = 土路。 (九)随堂练习(课本 p.5 语言点) 一、用所给动词的适当形式填空。 1. A: ______ you ______ (be) to the new library yet? B: No, I ______ (not know) there was one. 2. It ______ (open) last Friday. I ______ (go) there with my grandpa. 3. My grandpa ______ (listen) to some audio books because he can't see well. 4. Great changes ______ (take) place in Guizhou. The government ______ (build) many tunnels. 5. A journey that used to ______ (take) a day now ______ (take) only a few hours. 二、单项选择。 1. Have you finished your homework ______? A. already B. yet C. ever D. just 2. The Internet makes it easy ______ with friends far away. A. talk B. to talk C. talking D. talks 3. Most roads were just dirt ______ in the past. A. track B. tracks C. tunnel D. tunnels 4. They have built many high ______ and ______. A. bridge; tunnel B. bridges; tunnels C. bridge; tunnels D. bridges; tunnel 三、根据汉语意思完成句子。 1. 这使得当地人很难把产品运到市场。 This ______ it difficult for locals ______ ______ products to the market. 2. 我去过那个图书馆。 I ______ ______ to that library. 四、用 used to / now 描述交通变化。 1. In the past, there were no bridges in the mountains. Now, ______. 参考答案 一、1. Have; been; didn't know 2. opened; went 3. listened 4. have taken; has built 5. take; takes 二、1. B (yet 用于疑问句末) 2. B (make it + adj. + to do) 3. B (tracks 复数) 4. B (bridges; tunnels 复数) 三、1. makes; to; bring 2. have; been 四、1. (示例) Now there are many high bridges and tunnels, and the journey takes only a few hours. 【答题技巧】时态填空先找信号词:yet/in the past few years→现在完成时;last Friday→一般过去时;used to→过去状态;tomorrow→一般将来时。make it 后接形容词+to do。 易错提醒 ① 现在完成时 have/has + 过去分词,强调“过去发生、与现在相关”;与一般过去时(仅表过去动作)不同,别混用。 ② yet 用于疑问句/否定句句末(已经/还);already 用于肯定句(疑问句表意外),位置不同。 ③ used to + 动词原形,表过去常做/过去状态(现在已不);后接 be 用 used to be。 ④ make it + adj. + to do 中 it 是形式宾语,真正宾语是不定式,易误写成 make it difficult bring。 ⑤ track 作“小路/轨道”是可数名词,常用复数 tracks;tunnel 复数 tunnels,注意与 track 区分。 答题技巧 ① 圈动词三步法:读全句→找时间状语→判时态→写形式(4a 训练核心)。 ② 补全对话/短文先看上下文时态:同一话题常混合时态,逐句判断。 ③ yet 在疑/否句末、already 在肯定句中,单选题直接按位置选。 ④ make it + adj. + to do 结构题,空格后若接动词,必用不定式 to do。 语言点归纳 ● 四种时态:现在完成时(have/has done) / 一般过去时 / used to do / 一般将来时(will do)。 ● yet(疑/否句末,“已经/还”)vs already(肯定句,“已经”)。 ● make it + adj. + (for sb) + to do:it 形式宾语,不定式真宾语。 ● 核心词:course, digital, audio, dirt, track, wide, tunnel;搭配:digital books, audio books, dirt tracks, high bridges and tunnels。 课堂总结 本课时通过 4a 圈动词训练时态敏感度,在 4b 对话与 4c 短文中综合运用现在完成时、一般过去时、used to 与一般将来时描述家乡交通与生活的今昔变化; 掌握 yet / already 的位置区别与 make it + adj. + to do 结构; 积累 digital / audio / dirt / track / wide / tunnel / course 等交通与生活类核心词汇,提升语篇时态运用能力。 学科网(北京)股份有限公司 $
