Unit 8 Safe and sound（Grammar）

教学目标

1. Knowledge Aims

Students will be able to understand and use the past continuous tense correctly. They can describe an action that was in progress at a specific time in the past, such as “I was watching TV at 8 o'clock last night.”

Master the usage of conjunctions “when”, “while” and “as” in time - adverbial clauses. Differentiate the situations where each conjunction is used, like “When I got home, my mother was cooking.” (short action + long action), “While I was reading, my sister was listening to music.” (two long actions) and “As we walked, we talked.” (actions happening simultaneously).

Learn about compound words formed in different ways, including noun + noun (e.g., thunderstorm, teamwork), noun + verb (e.g., earthquake, rainfall), verb + noun (e.g., passport, playground) and adjective + noun (e.g., whiteboard, software), and be able to identify and create some simple compound words.

2. Ability Aims

Develop students' ability to analyze and summarize grammar rules through observing examples and practicing. For example, by comparing a series of sentences with the past continuous tense, they can figure out its formation and usage features.

Improve students' language application ability. They can use the learned grammar knowledge to describe past events and experiences accurately in speaking and writing. For instance, when writing a composition about an emergency they experienced, they can use the past continuous tense and relevant conjunctions properly.

Train students' listening and reading comprehension skills related to the grammar content. They can understand texts or dialogues that contain the past continuous tense and time - adverbial clauses, and answer related questions correctly.

3. Emotional Aims

Cultivate students' interest in learning English grammar by creating vivid and practical teaching situations. For example, using real - life emergency scenarios to illustrate grammar usage, making grammar learning less boring.

Encourage students to actively participate in classroom activities, enhancing their confidence in using English to express themselves. Through group discussions and pair work, students can overcome their fear of making mistakes and be more willing to try using new grammar knowledge.

重难点

1. Teaching Key Points

The formation and usage of the past continuous tense. The structure “was/were + verb - ing” should be firmly grasped by students, and they need to know when to use this tense to describe past actions.

The correct usage of “when”, “while” and “as” in time - adverbial clauses. Understanding the differences in the time range, verb nature and context matching of these three conjunctions is crucial.

The understanding and formation of compound words. Students should be able to recognize different types of compound words and create new ones based on the learned rules.

2. Teaching Difficult Points

Differentiating the past continuous tense from the simple past tense. The past continuous tense emphasizes the ongoing nature of an action in the past, while the simple past tense focuses on the completion of an action. Students often have trouble distinguishing between them, for example, confusing “I was reading a book when he came in.” and “I read a book yesterday.”

Using “when”, “while” and “as” accurately in complex sentences. In some cases, the choice of these conjunctions depends on the specific context and the relationship between the actions in the main and subordinate clauses, which can be confusing for students.

Applying compound words appropriately in writing and speaking. Although students can learn the formation rules of compound words, it is challenging for them to use them naturally
