discovering useful structures 导学案
课前导读
Content Analysis：
The activity theme of this module is "Report an ongoing event", and the target grammar structure is the passive voice of the present continuous tense. The rare wild animals are being poached on a large scale, and the species are on the verge of extinction. The rescue operation is underway. "Being" and "suffering" are exactly the meanings expressed in the passive voice of the present continuous tense.
Learning Objectives:
1. Learn the structure of the present continuous passive voice and its functions.
2. Learn to change the sentences with the present continuous tense into the sentences with the present continuous passive voice.
3. Learn to write sentences with the present continuous tense flexibly according to the context.
Activity Design：
The activity design of this module focuses on the theme of animal protection.
Activity 1: Let students find the present continuous passive voice in the sentence, initially perceive its form and function, and look for more sentences containing the present continuous passive voice in this unit.
Activity 2: Complete the sentences by selecting words, and guide the students to identify the meaning and function of the three language forms of the present progressive passive voice, the active voice and the present passive voice in a single sentence, and make preliminary use of them, paying attention to both language form and meaning comprehension.
Activity 3: This is a text filling activity. Students are required to fill in the blanks with the present continuous passive voice to make the text complete. This activity focuses on the present continuous passive voice. Students use different verbs to form the present continuous passive voice, repeatedly use the grammatical structure, and further understand and become familiar with its form, meaning and usage at a richer discourse level.
Activity 4: Let the students discuss what measures are being taken to protect animals and plants, put forward their own suggestions on animal and plant protection, and show them in the class. This activity requires students to pay attention to society, nature and teamwork.
Key points of Teaching:
Guide students to understand and correctly use the present continuous passive voice in the context.
