Revision and Lead-in

Ask the students to read the story “The Cat That Vanished”

again and find out the sentences with -ing.

T: First read the passage “The Cat That Vanished”

to find out sentences with -ing. Sample sentences:

1. Will was so tired that he could not think clearly, but as he

stood trying to decide what to do, he saw a cat.

2. Putting down his shopping bag, Will held out his hand, and the cat came up to him. 3. Still watching, Will saw the cat behave strangely. 4. When it had gone past he crossed the road, keeping his eyes on the place where the cat had vanished. 5. Pushing his shopping bag through, he climbed through the hole in the walls of this world and into another. 6. Bending to look through, he saw the road in his own town, his own world.

7. Feeling that he was dreaming but awake at the same time, he stood up and looked around for the cat, his guide.

Then ask the students to read aloud the sentences.

Step Ⅱ

Grammar Task 1: Grammar focus

T: From the sentences above, we can see that there is a comma in each sentence. And the two parts of each sentence refer to the same person. Now let’s find something more about -ing in the sentences. First, which sentences describe two things that happen at the same time? And which sentences describe one thing happening immediately after another?

Sa: Two things that happen at the same time: Sentences 1, 3, 4,

7. Sb: One thing happening immediately after another: Sentences 2, 5, 6. Then ask the students to do Activity 2 and then check the answers.

T: After the above exercises, we can conclude that -ing can sometimes be used to describe two things that happen at the same time, and sometimes describe one thing happening immediately after another. The two parts of each sentence refer to the same person. Besides, we can also put prepositions / conjunctions before -ing to form a phrase, such as while，when, once, although, until, if etc. And the phrase can be changed into an adverbial clause. For example, On seeing her, the king falls in love with her. can also be changed into: When the king sees her, he immediately falls in love with her.

T: The adverbial clauses with -ing can be used to indicate time, cause, condition, result, etc. These sentences can be changed into subordinate clauses or juxtapositional sentences. Now let’s do the following exercises.

Task2: 把动词-ing形式（短语）或独立主格结构作状语时，可转换为相应的状语从句。如：

1. Hearing the sad story, Emma was moved to tears. = When she heard the sad story, Emma was moved to tears.

2. Not having done physical exercise for some time, Tim is not as energetic as before. = Because he hasn't done physical exercise for some time, Tim is not as energetic as before. 3. Time permitting, I'd like to see the new film. = If time permits, I'd like to see the new film. Task 3: Practice
