教学过程
Lead-in: Song appreciation
(1) Play the song Take me to your heart before class.
(2) Start the class with a clip of the song sung by the teacher.
(3) Lead the Ss to notice the -ing form used as adverbials in the lyrics.
This is a warming-up step designed to arouse Ss’ enthusiasm and to come to the point.
Step 1: We Choose
Task 1: Observe the -ing form in each sentence and decide what it refers to.
(reason, result, concession, time, manner, condition)
1. Being very rich, he spends as much money as he likes. (reason)
2. Working hard, you’ll surely succeed. (condition)
3. They sat there, waiting for the beginning of the sports meeting. (manner)
4. Walking on the street, he came across a long-lost friend. (time)
5. The polar bear was not careful enough, falling on the icy ground. (result)
6. Not understanding what you are talking about, I still admire you. (concession)
It is intended to remind Ss that the -ing form can be used as various kinds of adverbials. Ask several Ss to answer and, if necessary, interpret the sentences for them with adverbial clauses.
Task 2: Check the words in red and decide their relation with the subject and the predicate. (A. active B. passive C. meanwhile D. before-after)
Laughing and jumping, he left school.
Having finished his homework, he left school.
Being talt at that time, he left school.
Having been punished, he left school.
First, let Ss choose the correct relation between the -ing form and the subject and that between the -ing form and the predicate in each sentence. Then lead Ss to sum up the differences among “doing”, “having done”, “being done” and “having been done”.
Task 3: Read the sentences aloud and recall the tips.
When the reading is finished, ask Ss how to use the -ing form as adverbials.
It is intended as a transition from “what” to “how” and the second step is naturally introduced.
