(2) Master the basic structure and usage of conditional clauses introduced by "if". The accuracy rate of answering relevant exercises should reach over 70%.
2. Cultural Awareness: Through reading and discussion, students will experience how different family cultures express love and create a warm atmosphere, thereby cultivating an understanding and tolerance of diverse family cultures.
3. Thinking Quality: Analyze information in reading materials, to develop summarizing and logical reasoning abilities.
4. Learning Ability: Learn to use skimming and scanning techniques to obtain key information from articles and improve reading efficiency.
二、教学重难点：
1. 重点: (1) Review and consolidate key vocabulary and sentence patterns.
(2) Deeply learn conditional clauses introduced by "if".
(3) Improve reading comprehension skills and master reading techniques.
2. 难点: (1) Understand and correctly use conditional clauses introduced by "if", paying attention to the tense collocation.
(2) Guide students to flexibly use the learned knowledge in writing to express their own opinions and ideas.
三、教学内容与过程：
Step 1. Review and Lead-in
(1) Use PPT to display some pictures of housework activities.
(2) Ask students to share the short passages about doing housework they wrote after class in the previous lesson.
Design intention: This step aims to activate students' prior knowledge related to housework. Showing pictures can spark students' interest and help them recall relevant vocabulary. Letting them share their written passages not only reviews previous learning but also offers a chance for them to practice speaking and build confidence.
Step 2. Grammar Explanation
(1) Present some sentences containing conditional clauses introduced by "if", such as "If it rains tomorrow, we will stay at home." and "If you help me with the housework, I will buy you an ice-cream." Guide students to observe the sentence structure and explain the composition and usage of conditional clauses introduced by "if".
(2) Emphasize the principle of "future tense in the main clause and present tense in the subordinate clause," that is, the main clause uses the simple future tense, and the subordinate clause uses the simple present tense to express future meaning.
Design intention: By presenting typical example sentences, students can observe and summarize the structure and usage of "if" conditional clauses on their own, which helps them understand grammar rules more deeply instead of just memorizing them. Highlighting the tense rule ensures students grasp the key point of using present tense in the subordinate clause and future tense in the main clause when talking about future conditions.
Step 3. Reading Training
Skimming: Display the reading material in 3a. Let students quickly skim through the passage and answer the question "What is the main idea of the passage " Guide students to learn to obtain the main idea of the passage through skimming and cultivate their ability of fast reading and summarizing.
Design intention: The goal here is to train students' ability to get the main idea of a passage quickly. Through skimming, students learn to focus on the most important information, improving their fast reading and summarizing skills, which are vital for efficient reading.
Scanning: Read the passage again. Let students read intensively with questions such as "Who did What to prepare for the grandparents' visit " and "What are the details about each person's preparation " Ask students to find the key information in the passage and mark it.
Design intention: This part aims to develop students' skill of locating specific details in a text. With targeted questions, students practice searching for key information accurately, enhancing their reading comprehension and attention to details.
Step 4. Writing Practice
Writing Guidance: Based on the reading passage and the content learned in this lesson, guide students to do a writing exercise. Give the writing topic.
Design intention: Guiding students to write based on the reading passage and learned content helps them connect reading with writing, making good use of the language they've acquired to express their own ideas. Providing a clear topic ensures they have a direction for their writing.
Student Writing: Let students write according to the points they listed. Require them to use the learned vocabulary, sentence patterns, and grammar knowledge, and try to make the sentences smooth and the expressions clear.
Design intention: Requiring students to use learned vocabulary, sentence patterns and grammar encourages them to apply what they've learned in practice. Focusing on smooth sentences and clear expressions helps them improve their writing quality gradually.
Presentation and Evaluation: Invite some students to share their compositions. Other students listen carefully and give evaluations, putting forward suggestions from aspects such as content completeness, language accuracy, and grammar correctness. The teacher finally makes a summary evaluation, affirms the students' advantages, points out the existing problems, and gives directions for improvement.
Design intention: Inviting students to share and evaluate each other's compositions creates an interactive learning environment. Peer evaluation helps students learn from each other, while the teacher's summary provides overall feedback, highlighting strengths and addressing problems to guide further improvement.
四、作业布置：
1. Recite the wonderful paragraphs in the reading passage to deepen the memory of vocabulary, sentence patterns, and expressions.
2. Modify the composition according to the evaluation opinions in class, and neatly copy the revised composition in the exercise book.
3. Preview the content of Section B, look up relevant information, and learn about the family cultural characteristics of some different countries.
五、教学反思：本次课以“家庭准备迎接祖父母来访”为主题，通过听力填空、问题回答、写作等以及角色扮演等活动，帮助学生提升英语听说能力与综合运用能力。
改进措施: (1) 加强听力策略指导：部分学生在填空时仅关注单词本身，忽略上下文逻辑。(2) 融入跨文化对比：可引导学生对比中西方家庭接待长辈的差异。
