Unit 8 Let's Communicate!-Section A-Grammar Focus
【教学目标】
Students are expected to master zero and first conditional sentences, including correct tense usage in clauses. They should be able to construct sentences like “If you want to solve the problem, a face - to - face talk usually works the best” to express real - life situations and future possibilities.
【教学重难点】
Grasp the structure and tense usage of zero and first conditional sentences. Zero conditionals for general truths and first conditionals for future possibilities. Practice constructing sentences in different communication situations.
【教学过程】
I. Greeting and Introduction
Teacher: Good morning, class! Today, we are going to explore an important part of English grammar in Unit 8 - Let's Communicate! We'll focus on the Grammar Focus section. As we know, communication is key in our daily lives, and using the right grammar helps us express our ideas more clearly. In this part, we'll learn about if - clauses, which are very useful when we want to talk about conditions and results. Are you all ready to dive in
Students: Yes!
II. Presentation of Grammar Focus Sentences
Teacher: First, let's look at some sentences on the screen. Read them aloud with me.
(Show the sentences on the PPT:
If you want to solve the problem, a face - to - face talk usually works the best.
Texting can make things worse if you’re not careful with your words.
If the rehearsal ends at 7:00 p.m., I’ll pick you up at 7:15 p.m.
If you stay calm and say sorry, it will help.
If I go there, I will try all the delicious local food.)
Teacher: Now, I want you to read these sentences carefully by yourselves and find more sentences with if - clauses in Section A of your textbooks. Then, translate all these sentences into Chinese. You can work in pairs.
(Students start to read and work in pairs. The teacher walks around the classroom, offering help and guidance.)
Teacher: Okay, let's stop here. Who would like to share the sentences you found and their translations
Student 1: I found “If you give a cat some milk, she will become your friend.” It means “如果你给一只猫一些牛奶，她就会成为你的朋友。”
Teacher: Great! Thank you. What about the others
Student 2: “If she becomes your friend, she will probably follow you everywhere.” Translation: “如果她成为你的朋友，她很可能会到处跟着你。”
Student 3: “If she follows you everywhere, she may want to play games with you.” It can be translated as “如果她到处跟着你，她可能会想和你玩游戏。”
Teacher: Wonderful! You all did a great job. Now, let's look at these sentences together again. Try to find the similarities among them. What do you notice
Student 4: They all have “if” in the sentences.
Teacher: Exactly! “If” is a very important word here. It starts a special part of the sentence, which we call the if - clause. What else
Student 5: There seem to be two parts in each sentence. One part starts with “if” and the other part is like a result.
Teacher: Very good observation! You are right. In an if - sentence, we have an if - clause (the part with “if”) and a main clause (the other part). Now, let's take a closer look at the tenses of the main clause and the subordinate clause (the if - clause).
III. Analyzing Tenses in If - Clauses
Teacher: Look at the first sentence again: “If you want to solve the problem, a face - to - face talk usually works the best.” What tense is the if - clause in
Students: (Think for a while and then some answer) Simple present tense.
Teacher: Correct! And what about the main clause
Student 6: Also simple present tense.
Teacher: Great. Now, look at the second sentence “Texting can make things worse if you’re not careful with your words.” Tense of the if - clause
Students: Simple present tense.
Teacher: And the main clause
Student 7: The main clause has “can make”, so it's a present tense with a modal verb.
Teacher: Excellent! You are all very sharp. Let's continue with the third sentence “If the rehearsal ends at 7:00 p.m., I’ll pick you up at 7:15 p.m.” Tense of the if - clause
Students: Simple present tense.
Teacher: And the main clause
Student 8: Simple future tense.
Teacher: Right! Now, I want you to look at all these sentences again and tell me in general, what tenses do we usually use in the if - clause and the main clause Discuss in your groups.
(Students discuss in groups. The teacher moves around, listening to their discussions and offering suggestions.)
Teacher: Okay, let's hear from each group. Group 1, would you like to start
Group 1 spokesperson: In the if - clause, it's usually simple present tense. And in the main clause, it can be simple present tense, present tense with a modal verb, or simple future tense.
Teacher: Very good! That's a great summary. In fact, when we talk about if - clauses, we have two main types: zero conditional sentence and first conditional sentence.
IV. Introducing Zero and First Conditionals
Teacher: Zero conditionals are used to talk about things that are always true, like scientific facts or general truths. For example, “If you heat ice, it melts.” This is a fact. The ice will always melt when you heat it. Can you think of some other zero conditional sentences
Student 9: If you drop an apple, it falls.
Teacher: Perfect! What about another one
Student 10: If you mix red and blue, you get purple.
Teacher: Great examples! Now, let's talk about first conditionals. First conditionals are used to talk about things that will possibly happen in the future. For example, “If it rains tomorrow, I will stay at home.” Here, we are talking about a possible situation in the future. Can you make some first conditional sentences
Student 11: If I finish my homework early, I will watch TV.
Teacher: Good one! How about someone else
Student 12: If my parents give me money, I will buy a new book.
Teacher: Excellent! Now, let's do some exercises to practice using these zero and first conditionals.
V. Exercises
Teacher: (Show Exercise 3a on the PPT) Look at these incomplete sentences. We need to match the two parts to make correct if - sentences. Let's do the first one together. “If we have a face - to - face meeting,” what could be a good result
Student 13: I think “I think we will understand each other better.”
Teacher: Right! Because when we meet face - to - face, we can communicate better and understand each other more easily. Now, you do the rest on your own.
(Students do the exercise. The teacher checks the answers after a few minutes.)
Teacher: Let's check the answers. For the second one, “If I have good news,” what's the answer
Students: “I will call you immediately.”
Teacher: Correct. Third one, “If you need to leave,”
Student 14: “You can write things down for him.”
Teacher: Well done. Fourth one, “If you can finish your work early today,”
Student 15: “Would you like to have dinner with me ”
Teacher: Good. Fifth one, “If the old man has trouble hearing,”
Student 16: “I will call a taxi for you.”
Teacher: Right. And the last one, “If you can't reach him by phone,”
Student 17: “Try sending a text message.”
Teacher: Perfect! You all did a great job. Now, let's move on to Exercise 3b. In this exercise, you need to complete the sentences using the correct form of the verbs in the brackets. This will help you practice using the right tenses in if - clauses and main clauses. Let's start with the first one. “If it _ (rain) tomorrow, we _ (not go) to the park.” What should we fill in
Student 18: rains; won't go
Teacher: Exactly! Remember, in the if - clause, we use the simple present tense, and in the main clause, because it's a future situation, we use “will + verb” form, and here it's negative, so “won't go”. Now, you do the rest.
(Students do the exercise. The teacher checks the answers later.)
Teacher: Let's check. Second one, “If he _ (come) to the party, I _ (be) very happy.”
Student 19: comes; will be
Teacher: Right. Third one, “If you _ (not study) hard, you _ (fail) the exam.”
Student 20: don't study; will fail
Teacher: Good. Fourth one, “If they _ (arrive) on time, we _ (start) the meeting at once.”
Student 21: arrive; will start
Teacher: Well done. Fifth one, “If she _ (find) her lost keys, she _ (be) very excited.”
Student 22: finds; will be
Teacher: Perfect. Now, for the last exercise in this part, Exercise 3c. I want you to write five if - sentences on your own. They can be either zero conditionals or first conditionals. Then, exchange your sentences with your partner and check each other's work.
(Students write sentences and exchange with their partners. The teacher walks around to check and offer help.)
Teacher: Okay, let's stop here. Who would like to share one of the sentences you wrote
Student 23: If I get good grades this term, my parents will buy me a new bike.
Teacher: That's a great first conditional sentence. What about someone else
Student 24: If you put water in the freezer, it turns into ice. This is a zero conditional sentence.
Teacher: Excellent! You all showed a good understanding of if - clauses.
VI. Summary
Teacher: Today, we learned a lot about if - clauses. We learned about zero conditionals for general truths and first conditionals for future possible situations. We also practiced using the correct tenses in if - clauses and main clauses. Remember, grammar is important, but the key is to use it in real - life communication. So, try to use if - sentences when you talk to your friends, family, or even when you write in your English diaries.
VII. Homework
Teacher: For homework, I want you to write a short passage about your plans for the weekend using at least three if - sentences. You can think about what you will do if the weather is good, if you have enough time, or if your friends invite you to do something. Bring your passages to class tomorrow, and we will share them.
Teacher: That's all for today's class. Have a great day!
