《Unit 3 Online travel》Period 6 Grammar（2）
Teaching aims:
1. To become familiar with the function of the word ‘by’ to indicate the agent who does something.
2. To complete some exercises to practice using the passive voice.
Step 1 greeting & presenting
Explain that we can also use the passive voice when we want to mention the doer or agent who does something. Introduce the concept of “by” which enables us to say the name of the doer. We can use “by” to say who or what does the action.
Step 2 Teaching
Present the sample sentences in table forms to give Ss a visual support for the concept.
Change the active voice sentences into the passive voice sentences.
(1) Mr. Lin organizes activities for the Computer Club.
(2) Nancy Jackson designed that CD-ROM.
Ask Ss to complete “work out the rule!” on their own. Ask a volunteer to read out the rule.
Step 3 Exercise
Finish the excise on Page 48 &Page 49
1. Ask Ss to study the pictures carefully and the words below each one. Ss identify any words they do not know. Help Ss understand the meanings of words so that they are able to enjoy the fun element of the overall story rather than spend too much time on vocabulary details. You may have to review ‘magic wand’, ‘princess’ and ‘witch’. Explain the context and instructions.
2. Ask Ss to write out the sentences for Part B1 on their own.
3. Ask seven Ss to read out one sentence each. Repeat the sentences clearly and ask Ss to check their own work.
Step 4 exercise
Complete the sentences in the passive voice. Use the correct forms of the verbs in the box.
build eat paint steal
catch grow sell write
