5. Ss can apply grammar knowledge to solve practical problems in exercises and reading tasks.

Cultural Awareness:

7. Ss can appreciate the great achievements in China's infrastructure, such as the bridges and highways in Guizhou, and feel proud of the country's rapid development.

 

Key and Difficult Points:

Key point

Ss can master the sentence structures of the simple past tense and the present perfect tense, and identify their time markers.

 

Difficult point

Ss can distinguish the subtle differences between the two tenses in specific contexts, especially understanding that the present perfect tense emphasizes the impact on the present, while the simple past tense only states a past fact.

 

Teaching Procedures:

 

Step 1. Lead - in and Review

1). Play a short song and ask Ss to identify the verb tenses used in the lyrics.

2). Show sentences about changes learned in previous lessons. Ask Ss to

fill in the blanks with the correct forms of the given verbs (e.g., "became", "haven't seen", "used", "has built").

3). Guide Ss to circle the verbs in these sentences and pay attention to the different tenses used.

 

Step 2. Presentation of Grammar Rules (Simple Past Tense)

1). Explain the definition of the simple past tense: an action or state that happened at a specific time in the past.

2). Show the timeline to illustrate it is separated from "now".

3). Present the structures:

   - With "be" verbs: was/were + others.

   - With action verbs: verb-ed (past form).

4). List the common time markers: "yesterday", "last week/month/year", "... ago", "in 2020", "just now".

5). Show the sentence structures for affirmative, negative, general questions, and special questions.

 

Step 3. Presentation of Grammar Rules (Present Perfect Tense)

1). Explain the definition: an action that happened in the past but has an impact or result on the present, or an action that started in the past and continues to the present.

2). Show the timeline to illustrate the connection between the past and
