Unit 6 Then and now 外研版(三起)五年级下册 1.7.2013 Hello, boys and girls! Welcome to our English class. Today, we are going to learn Unit 6, "Then and now". Let's explore the changes around us together! ‹#› 目录 01. Warm-up & Lead-in 热身与导入 02. Vocabulary & Sentences 词汇与句型 03. Text Learning 课文学习 04. Grammar Focus 语法聚焦 05. Practice & Exercises 练习与巩固 06. Summary & Homework 总结与作业 1.7.2013 Here is our study plan for today. We will start with a warm-up, then learn new words and sentences, go through the text, focus on some grammar points, do lots of practice, and finally summarize what we've learned and set our homework. ‹#› Warm-up & Lead-in What can you see in the pictures? What are the differences between them? Can you think of more changes in our life? 1.7.2013 Look at the two pictures. On the left, there is an old telephone. On the right, there is a modern smartphone. They are very different. This is what we call "Then and now". Our life is changing all the time. Can you find more examples of changes? ‹#› Vocabulary: Appearance young /jʌŋ/ 年轻的 old /əʊld/ 年老的 tall /tɔːl/|short /ʃɔːt/ 高的 / 矮的 thin /θɪn/|fat /fæt/ 瘦的 / 胖的 1.7.2013 Let's learn some words to describe people's appearance. Look at the picture. The boy was young then, but he is old now. He was short then, but he is tall now. He was thin then, but he is fat now. Repeat after me: young, old, tall, short, thin, fat. ‹#› Vocabulary: Time & Ability Time Words (时间) then /ðen/ 那时 now /naʊ/ 现在 ago /əˈɡəʊ/ ...以前 Ability Words (能力) could /kʊd/ 能 (过去式) couldn't /ˈkʊdnt/ 不能 1.7.2013 Now, let's learn words about time and ability. "Then" means in the past, and "now" means at the present. "Ago" is used to talk about a time in the past, like "three years ago". "Could" is the past form of "can", and "couldn't" is the negative form. For example, three years ago, he couldn't ride a bike, but now he can. ‹#› Sentence Pattern (1) Core Pattern Then I was... / Now I am... Example 1: Height Then I was short. Now I am tall. Example 2: Age Then I was young. Now I am old. 1.7.2013 This is our first key sentence pattern for talking about changes in appearance. We use "Then I was..." to talk about the past and "Now I am..." to talk about the present. For example, "Then I was short. Now I am tall." Let's practice saying this sentence together. ‹#› Sentence Pattern (2) Core Structure Then Icouldn't... Now Ican... Then I couldn't swim. Now I can swim very well. Then I couldn't ride a bike. Now I can ride a bike. 1.7.2013 Our second sentence pattern is for talking about changes in abilities. We use "Then I couldn't..." to say we were not able to do something in the past, and "Now I can..." to say we are able to do it now. Like this: "Then I couldn't swim. Now I can swim very well." Let's try to make our own sentences. ‹#› Sentence Pattern (3) Core Structure: Past vs Present There was/were... → Now there is/are... Example 1: Building Change There was a small house here. Now there is a big building. Example 2: Environment Change There weren't any trees here. Now there are many trees. 1.7.2013 The third pattern is for talking about changes in places or environments. We use "There was/were..." for the past and "There is/are..." for the present. For example, "There was a small house here. Now there is a big building." This is the "there be" structure in different tenses. ‹#› Text Learning: Part 1 Look at the picture What are Lingling and Amy doing? Observation They are looking at some photos. Let's Find Out Whose photos are these? Let's check the text. 1.7.2013 Now, let's move on to our text. Look at the picture. Lingling and Amy are looking at an album. They are talking about the people in the photos. Let's listen and read to find out who they are talking about. ‹#› Part 1 (Dialogue) Sam:Who are they, Lingling? Lingling:They're my grandparents. Sam:Who's this? Lingling:It's my grandma. Shewasadancer. She danced in lots of Chinese cities. Amy:Did she learn any foreign languages? Lingling:Yes, shelearntEnglish. Amy:Is this your grandpa? Lingling:Yes, it is. Hewasadriver. Amy:Did he learn English too? Lingling:No, he didn't. But he's learning English now! 1.7.2013 Here is the dialogue between Sam, Amy, and Lingling. They are talking about Lingling's grandparents. Her grandma was a dancer and she learnt English. Her grandpa was a driver and he didn't learn English, but he is learning it now. Let's read the dialogue together. ‹#› Key Points: Part 1 Key Vocabulary (重点词汇) dancer(舞者) driver(司机) learnt(学习，过去式) Key Sentences (重点句型) Shewasa dancer. 描述过去的职业 (一般过去时) ShelearntEnglish. 描述过去的动作 (动词过去式) Did she learn any foreign languages? 一般过去时的一般疑问句 1.7.2013 Let's look at the key points from this part. We use "was/were" to talk about jobs in the past. We also use the past tense of verbs, like "learnt", to talk about actions that happened in the past. The question "Did she learn...?" is a common way to ask about past actions. ‹#› Read and Imitate Sam:Who are they, Lingling? Lingling:They're my grandparents. Sam:Who's this? Lingling:It's my grandma. She was a dancer. She danced in lots of Chinese cities. Amy:Did she learn any foreign languages? Lingling:Yes, she learnt English. Amy:Is this your grandpa? Did he learn English too? Lingling:Yes, he was a driver. No, he didn't learn English then, but he's learning now! 1.7.2013 Now, let's read the dialogue again. This time, try to imitate the pronunciation and intonation of the speakers. You can read in pairs, one as Sam/Amy and the other as Lingling. ‹#› Text Learning: Part 2 Look at the pictures. They show a school then and now. What was Mr. Li's job? What was Chen Hai like? Let's read the text carefully to find the answers. 1.7.2013 Now, let's read the second part of the text. It's about changes in a school. The pictures show a classroom in the past and now. Let's read to find out about Mr. Li and Chen Hai. ‹#› Part 2 (Passage) Twenty years ago, Mr Liwasa teacher. HetaughtChinese. Chen Haiwasin his class. Hewasa goodpupil. Hestudiedvery hard. Five yearsago, thereweren'tany computers in the classroom. Now therearecomputers in the classroom. 1.7.2013 Here is the passage about Mr. Li and the school. Twenty years ago, Mr. Li was a Chinese teacher, and Chen Hai was his student. Chen Hai studied very hard. Five years ago, there were no computers in the classroom, but now there are. Let's read this passage carefully. ‹#› Key Points: Part 2 Important Vocabulary taught(教，过去式) pupil(学生) studied(学习，过去式) Key Sentence Patterns 1. 数字 + 时间 + ago (多久以前) • Twenty years ago... / Five years ago... 2. There be 句型的过去式 • There weren't any computers... • Now there are computers... 1.7.2013 From this part, we learn how to talk about time in the past using "ago". We also review the "there be" structure in the past tense with "was/were". This is very useful for talking about changes in places over time. ‹#› Read Aloud Twenty years ago, Mr Li was a teacher. He taught Chinese. Chen Hai was in his class. He was a good pupil. He studied very hard. Five years ago, there weren't any computers in the classroom. Now there are computers in the classroom. 1.7.2013 Now, let's read the passage aloud. You can read it by yourself first, then read it with your partner, and finally, we can read it together as a class. Pay attention to the pronunciation of the past tense verbs. ‹#› Grammar Focus: Be动词的过去式 现在时 过去式 主语示例 例句 am / is was I, he, she, it Iwasa student. Shewashappy. are were we, you, they Theywerein the park. Youwerelate. 1.7.2013 Now, let's focus on the grammar. The past forms of "am" and "is" are "was". The past form of "are" is "were". We use "was" with I, he, she, it, and "were" with we, you, they. Let's look at the examples in the table. ‹#› Grammar Practice (1) Fill in the blanks with "was" or "were". 1. I ______ short then. 2. They ______ in the park yesterday. 3. She ______ a teacher ten years ago. 4. We ______ happy at the party. 5. He ______ thin last year. 1.7.2013 Let's practice using "was" and "were". Please fill in the blanks in these sentences. You can discuss your answers with your partner. ‹#› Grammar Focus: 规则动词过去式 一般情况 直接加-ed work → worked play → played 以 e 结尾 直接加-d live → lived dance → danced 辅音字母 + y 变 y 为 i, 加-ed study → studied try → tried 1.7.2013 Next, let's learn about regular verbs in the past tense. Most verbs form their past tense by adding "-ed". There are some spelling rules: add "-d" if the verb ends in "e", and change "y" to "i" and add "-ed" if the verb ends in a consonant + "y". ‹#› Grammar Focus: 不规则动词过去式 learn→learnt teach→taught study→studied ride→rode wear→wore do→did 1.7.2013 Some verbs have irregular past forms, which don't follow the "-ed" rule. We need to memorize them. Here are some irregular verbs we saw in the text, like "learn-learnt", "teach-taught", and "go-went". Let's try to remember them. ‹#› Grammar Practice (2) Write the past tense of the following verbs. 1. play → __________ 2. go → __________ 3. watch → __________ 4. eat → __________ 5. study → __________ 6. learn → __________ 1.7.2013 Now, let's practice writing the past tense of some verbs. Some are regular and some are irregular. Please write down the past forms. ‹#› Practice: Look and Write Look at the pictures and write sentences using "Then... Now...". 1. A boy: short → tall Then he was short. Now he is tall. 2. A girl: couldn't swim → can swim Then she couldn't swim. Now she can swim. 3. A school: small → big Then it was small. Now it is big. 1.7.2013 Let's do some more practice. Look at the pictures and try to make sentences using the patterns we learned: "Then... Now...". I'll do the first one as an example. ‹#› Practice: True or False 1. Lingling's grandma was a driver. ( ) 2. Lingling's grandma learnt English. ( ) 3. Mr Li taught English twenty years ago. ( ) 4. Chen Hai was a good pupil. ( ) 5. There were computers in the classroom five years ago. ( ) 1.7.2013 Now, let's check our understanding of the text. Read these sentences and decide if they are true or false according to what we learned. ‹#› Practice: Complete the Dialogue A: Hello, Tom. ______ you at home yesterday? B: Yes, I ______. A: What ______ you do? B: I ______ my homework and ______ TV. A: ______ you play computer games? B: No, I ______. I ______ play computer games then. 1.7.2013 Let's practice in a more challenging way. Try to complete this dialogue with the correct words. You can work in pairs to finish it. ‹#› Practice: Multiple Choice 1. - ______ you at home yesterday? - Yes, I ______. A. Are, am B. Was, was C. Were, was 2. He ______ TV last night. A. watch B. watches C. watched 3. There ______ a small house here five years ago. A. was B. were C. is 4. I ______ ride a bike when I was five. A. can B. couldn't C. am 1.7.2013 Here are some multiple-choice questions. Please choose the best answer for each one. This will help us review what we've learned. ‹#› Extension: Talk about Yourself Task: Talk about the changes in yourself. Then I was__________. Now I am__________. Then I couldn't__________. Now I can__________. Share your sentences with your partner. 1.7.2013 Now it's your turn to talk about yourselves. Think about how you have changed. Use the sentence patterns on the screen to describe your changes. Share your ideas with your partner. ‹#› Extension: Talk about Your School Task: Talk about the changes in your school or hometown using the structures below. In the Past There was/were ______. Now There is/are ______. Example There was a small playground. Now there is a big gym. 1.7.2013 Let's think bigger. Talk about the changes in your school or your hometown. How has it changed over the years? Use the "there be" structure to describe what was there before and what is there now. ‹#› Fun Activity: Role-play Task: Then and Now Work in pairs (两人一组) Student A: Act as "You in the past" Student B: Act as "You now" Talk about the changes using the sentences. Example Dialogue A (Past):Hello, I'm you from 5 years ago. I was short. B (Now):Hello, I'm you now. I am tall. 1.7.2013 Let's have some fun with a role-play activity. Work with a partner. One of you will be the "past you" and the other will be the "present you". Use the sentences we learned to have a conversation about your changes. ‹#› Fun Activity: Find the Differences Picture 1 (Then) An old street with a bike. Picture 2 (Now) A new street with many cars and tall buildings. Try to describe: There was a bike, but now there are many cars. There were small houses, but now there are tall buildings. 1.7.2013 Another fun activity: Find the differences! Look at the two pictures of a street. One is from the past and the other is now. Can you find the differences? Try to describe them using the sentences we learned, like "There was..., but now there is...". ‹#› Summary: Vocabulary Appearance (外貌) young, old, tall, short, thin, fat Abilities (能力) can, could, couldn't Time (时间) then, now, ago Jobs (职业) dancer, driver, teacher, pupil Past Tense (过去式) was, were, learnt, taught, studied, worked... Key Takeaway Use these words to describe people and talk about the past. 1.7.2013 Let's summarize what we've learned today. First, let's review the key vocabulary. We learned words to describe appearance, abilities, time, jobs, and many past tense verbs. ‹#› Summary: Sentence Patterns 外貌变化 Appearance Pattern: Then I was... Now I am... Example: Then I was short.

Example: There was a small house. Now there is a big building. 1.7.2013 Next, let's review the three key sentence patterns we used to talk about changes: describing changes in appearance, abilities, and environments. These patterns are very useful for talking about "then and now". ‹#› Summary: Grammar Be 动词的过去式 am / is →was are →were 实义动词的过去式 规则变化：+ed / +d / 变y为i+ed 不规则变化：learn→learnt, go→went 一般过去时的用法 描述在过去时间发生的动作 描述在过去存在的状态 1.7.2013 Finally, let's review the grammar focus: the past tense. We learned how to use "was" and "were" for the verb "be", and how to form the past tense of regular and irregular verbs. Remember, we use the past tense to talk about things that happened or were true in the past. ‹#› Class Quiz 1. Fill in the blanks I ______ (be) short then, but now I ______ (be) tall. 2.
