UNIT 07 GRAMMAR FOCUS The Simple Past Tense 一般过去时 Review actions or states that happened in the past 1.7.2013 大家好，欢迎回到英语课堂！今天我们要学习一个非常重要的语法点——一般过去时。它能帮助我们回顾和讲述过去发生的事情。准备好了吗？让我们一起开始探索过去的世界吧！ ‹#› Look and Say What can you see in the picture? Look closely at the details. Who is in the picture? What are they doing? Try to list out 3 things you notice. What did the students do at the festival? Identify the activities shown, like singing songs, playing the guitar, or painting a picture. What other fun things might they have done? Let's use "Yesterday" to talk about it. Make a complete sentence using the word "Yesterday". For example: "Yesterday, the students sang at the art festival." 1.7.2013 看这张图片！这是我们学校上周的艺术节。你能在图片里看到什么？学生们在艺术节上做了什么？让我们试着用“昨天”来描述一下。鼓励大家大胆开口，即使说得不完整也没关系。 ‹#› Dialogue Amy:Hi, Ben! How was your school art festival yesterday? Ben:It was great! I sang a song with my friends. Amy:Cool!Did you sing an English song? Ben:Yes, we did. We sang"Big Big World". We won the first prize! Amy & Ben:I drew a picture. But I didn't win a prize. Congratulations! 1.7.2013 现在，让我们来读一段对话。Amy 和 Ben 在谈论昨天的艺术节。请和你的搭档一起朗读。注意加粗的动词，它们和我们平时用的动词有什么不同？这些就是我们今天要学习的“过去式”。 ‹#› 规则动词的过去式 (Regular Verbs) 一般情况 General Rule 最基础的变形规则：直接在动词原形词尾加后缀-ed。 发音规则 Pronunciation Rules • 清辅音后读 /t/ (e.g., look → looked) • 浊辅音/元音后读 /d/ (e.g., play → played) • /t/ /d/ 音后读 /ɪd/ (e.g., visit → visited) 典型示例 Examples look → looked play → played visit → visited watch → watched 1.7.2013 动词的过去式分为规则和不规则两种。我们先来看规则动词。最基本的规则就是直接在词尾加-ed。比如 look 变成 looked。同时要注意它的三种发音规则，跟我一起读一读。 ‹#› Practice 1: Add "-ed" 用所给动词的正确形式填空。 01 I(watch) a movie last night. 02 She(visit) her grandparents last weekend. 03 They(play) basketball after school yesterday. 04 He(look) at the picture carefully just now. 05 We(listen) to some music in the classroom. 06 My mother(need) to buy some food for dinner. 1.7.2013 现在我们来练习一下。请用所给动词的过去式填空。注意时间状语，它们都表示过去。大家可以和同桌讨论一下。 ‹#› 规则动词的过去式 (Special Cases) CASE 01 以不发音的 “e” 结尾 直接在词尾加 “-d” live → lived| dance → danced CASE 02 “辅音 + y” 结尾 变 “y” 为 “i”，再加 “-ed” study → studied| try → tried CASE 03 重读闭音节结尾 双写末尾辅音，再加 “-ed” stop → stopped | plan → planned 1.7.2013 除了一般规则，还有三种特殊情况需要我们注意。第一种是以不发音的e结尾，直接加d。第二种是以辅音字母加y结尾，要变y为i再加ed。第三种是重读闭音节结尾，需要双写末尾辅音字母再加ed。大家看例子，理解一下。 ‹#› Practice 2: Special Cases 写出下列动词的过去式 (Write the past tense): 01 live 02 study 03 stop 04 dance 05 try 06 plan 07 like 08 carry 1.7.2013 现在来练习这三种特殊情况。请写出这些动词的过去式。注意区分它们分别属于哪一种情况。 ‹#› 一般过去时的一般疑问句 核心结构 Structure 句型公式：Did+ 主语 +动词原形+ ... ? 注意：无论主语是单数还是复数，助动词都用 Did 标准回答 Answer 肯定：Yes, 主语 +did. 否定：No, 主语 +didn't. 转换示例 Example 陈述句：He played football yesterday. 疑问句：Did he play football yesterday? 1.7.2013 学会了陈述句，我们再来看看如何提问。一般过去时的一般疑问句结构是：Did + 主语 + 动词原形。注意，这里的动词一定要用原形！回答也很简单，用Yes, ... did. 或 No, ... didn't. ‹#› Practice 3: Change into Questions 将下列陈述句变为一般疑问句，并给出肯定和否定回答。 01 She cleaned her room. Question: Answer: Yes,____________. / No,____________. 02 They played computer games. Question: Answer: Yes,____________. / No,____________. 1.7.2013 我们来做句型转换练习。把这些陈述句变成一般疑问句，并写出简短回答。记住，动词要用原形哦！ ‹#› 不规则动词的过去式 有些动词的过去式没有固定规则，需要我们特别记忆。 be (am / is / are) → was / were go(去) → went see(看见) → saw have / has(有) → had eat(吃) → ate buy(买) → bought sing(唱) → sang write(写) → wrote take(拿/取) → took make(做/制造) → made 1.7.2013 接下来是难点，也是重点——不规则动词。这些动词的过去式没有规律，只能靠我们花时间去记忆。屏幕上是一些最常用的不规则动词，大家跟我一起读，并努力记住它们。 ‹#› Practice 4: Irregular Verbs 请根据句意，用括号内所给动词的正确过去式形式填空。 01 He(go) to the park with his friends yesterday afternoon. 02 I(see) a big black dog running on the street just now. 03 She(have) a wonderful birthday party with her family last month. 04 They(eat) beef noodles for dinner because they were hungry. 05 My father(buy) me a cool new mountain bike on my birthday. 06 We(sing) and(dance) happily at the Christmas party. 1.7.2013 现在来检验一下大家的记忆成果。请用这些不规则动词的过去式填空。注意，这些动词的过去式变化非常特殊，一定要仔细回忆。 ‹#› Practice 5: Cloze Test (Part 1) 阅读对话，用所给动词的正确形式填空，注意一般过去时的用法。 Dialogue Linda:Hi Peter!
