[高一]Unit 2 In the lab Lesson 5(人教版)

Step 1. Lead in
Ask the students some questions about their subjects that are learned this term, such as:
(1) How many subjects do you learn this term ?
(2) What are they? (in order to make them review the words they learnt in the last unit.)
(3) Which subject(s) do you like best? (Which is your favorite subjects ? )
(4) What do you think of chemistry ?
(5) What do you do sometimes?
(6) Where do you do the experiments ?
(7)In the chemistry lab you have to follow the teacher 's instructions. Do you agree? So what instructions may the teacher ask you to follow ?
The students may have a discussion about it and then each group has one reporter show their group's opinion.
Step 2. Listen to the dialogue
Collect the students’ instructions and then put them on the blackboard as fast as possible.Then ask them to listen to the dialogue for the information they have not mentioned. After listening the students point out the instructions that they did not mention just now. Then the students are supposed to act out the dialogue. (group work) Four students form a group and one of them is the teacher who is supposed to tell the other three students what they must do and what they must not do when they have chemistry in the lab.
Step 3. Read the dialogue
Get the students to use the Look--speak method.They should look at their books before they speak the words. When they speak the words they should look at their partners. This method helps them remember the dialogue.
Step 4. Language points
Step 5. Language focus
Get the students to identify the different structures that are used for giving instructions. Write them on the blackboard:
Don't ……/Listen….. to/ Follow/ Do ……
Please do ……/Make sure ……/Do …… is allowed ./Don't forget to ……
Point out that " allow " is usually used in the Passive when we give instructions.
Step 6. Practice
Do Part Two of SB on page 5. Do one or two examples with the whole class, then let the students work in pairs. Finally to through the exercises with the whole class for checking/extra practice. If possible let the students put forward some other instructions by giving them some other situations, such as, what you must do and must not do when you are in the hospital /library / reading room park, etc. Give some group the same task and others different tasks .Then let them show the result of their discussion.
