The focus of teaching：Object clause
The presentation of teaching：
The first period
Part A Object clauses introduced by ‘wh-’ words
Step　1　 Revision , show some sentences about Object clauses
(1) Review object clauses introduced by ‘that’.

I think (that) he can do the work well.

b. 警察想知道受害人是否有敌人.
The police wanted to know if/whether the victim had any enemies.
Step  2 　Object clauses introduced by ‘wh-‘ words
(1) Tell students that when object clauses relate to ‘wh-’ questions, we should use ‘wh-’ words to introduce object clauses. Ask students to read the grammar rules and the two example sentences at the top of page 25.
(2) Remind them that the clause should be introduced by ‘wh-’ words and the word order in the clause should be the same as in a statement.
(3) Ask students to do the exercise on page 25. Then check the answers as a class.
(4) Write the following sentences on the board.
a. Where is Sam?
b. How did you go to school this morning?
c. What will you do next Monday?
d. When did the film begin?
e. Who wrote the book?
Ask students to make sentences containing object clauses with the sentences above orally. Then ask them to write down:
a. Do you know _______________________________________________?
b. I can’t imagine _________________________________________________.
c. I’d like to know ________________________________________________.
d. I am not sure __________________________________________________.
e. Can you tell me ________________________________________________?

The second period
Part B ‘in order to’ and ‘as a result’
Step 1
Ask ‘If you want to have more free time, what will you do?’ Help Ss to answer with ‘In order to have more free time, we should …’
  e.g. In order to have more free time, we should make good plans.
     We should make good plans in order to have more free time.
Step 2
Explain to students that ‘in order to’ means ‘with the purpose of’ and that we can use ‘in order to’ to introduce the purpose of an action.
Tell students that ‘in order to’ can be used at the beginning or in the middle of a sentence. Remind them when we use ‘in order to’ at the beginning a sentence, we use a comma to separate the two parts.
Step 3
 Go to ‘as a result’ by reviewing the sentence ‘The victim was attacked with a knife and bled to death as a result.’
  Remind Ss that we use ‘as a result’ to introduce the result of something.
Step 4
 Ask some volunteers to read the grammar rules and example sentences at the top of page 26 to the class.
Step 5
Ask Ss to do the exercises on page 26 which requires Ss to decide whether a sentence is talking about the purpose of result of something and add ‘in order to’ or ‘as a result’ to make a complete sentence.
Step 6
 Ask Ss to complete the ‘Work out the rule!’ on their own.
Part C Using ‘need to’
Step 1
1 Ask Ss ‘If you are hungry, what do you want to do?’
2 Help them to answer like: ‘I’m hungry. I need to eat.’
3 More practice:
  I’m thirsty. I need something to drink.
  I’m tired.  I need to get some sleep.
  I’m cold.  I need to wear more clothes.
Step 2
  Explain to Ss that ‘need to’ is a strong verb. We use it when we want to talk about something we should do. Tell them that the meaning is similar to, yet weaker than ‘must’.
Step 3
  Ask Ss what things they need to do today. Encourage them use ‘need to’.
Step 4
  Ask Ss to read the example sentences on the top of page 27. Then ask them to work on their own to complete the exercise using ‘need to’ and the phrases in the box.
Step 5
  Ask Ss to complete the ‘Work out the rule!’ on their own. Then ask Ss ‘Do we use the simple past tense after need to?’  (No.)
