T: Have you ever watched the programme “Dad, where are we going”?
S: Yes!
T: What do you think of this programme?

Step 2 Presentation
1. Explain to-infinitives
T: In these two sentences, we use “to go fishing” and “to buy some food” to express our purposes. That’s what we are going to learn today.
2. Find the to-infinitives
T: There are also some sentences with to-infinitives for purpose in the reading part. Can you find them out?

S2: The members of our Birdwatching Society go to study the birds in Zhalong.

T: Pay attention: Don’t forget a comma to separate the two sentences when “in order to” comes at the beginning of the sentence.
【设计意图：系统讲解“to do sth.”和“in order to do sth.”的用法。

Step 3 Practice
1. Describe the pictures with “to-infinitives”

and “in order to”. For example: The children play football to keep fit in the first picture.
T: What about the second one? Where are the children now?
S: In the cave.
T: Why do the children go into the cave?

T: So they put on more coats in order not to catch a cold. Pay attention to the negative meaning.【设计意图：利用学生们喜爱的节目来操练“to do sth.”和“in order to do sth.”。

B Using verbs + object + to-infinitives
Step 1 Presentation
1. Explain to-infinitives as object complement
(1) Find to-infinitives
T: In fact, there are more sentences with “to-infinitives” in the article. Can you find them out? S1: We are now inviting them to help us.
S2: We need more people to count and describe the birds.
T: Pay attention to the structures: “invite sb. to do sth.” and “need sb. to do sth.”.
(2) Work out the rule
T: Let’s work out the rule: verbs + object + to-infinitives. Verbs of this kind include “tell, ask, invite, need, and want”. Do you know how to express a negative meaning?
S: We can add “not” in front of “to do sth.”
T: Perfect! That is “tell, ask, invite, need, and want” + “sb. not to do sth.”.
(3) Fill in the blanks and check the answers
T: Something interesting is happening between fathers and children. Do you want to know?
S: Yeah!
T: Let’s fill in the blanks to see what happened to them.
The villagers invited fathers and their children _____ (come) to dinner in their homes.
The members of the Birdwatching Society teach children _____ (count) the birds.
The Head of the Village told children _____ (not play) near the lake.
Children helped their fathers _____ (do) the housework.
2. Explain to-infinitives without “to” as object complement
(1) Show some examples
T:This time fathers and children had a good time in the zoo. What did they see? Let’s go and have a look.
T: They watched a monkey ride a bike.
They saw an elephant play football.
They saw a tiger jump through rings.
The zookeeper let/made the dolphins play some tricks.
They heard many people shout excitedly.
(2) Work out the rules:
T: From these examples, we have known that we can use some verbs with infinitives without “to”. Let’s sum up the verbs together.
T: Among all children, I think the boy Stone is the most energetic. So we often see Stone run quickly, right? But now, he isn’t running. Just now I saw Stone playing football with his father and Kimi. So when an action often happens and when we see the whole process of an action, we can use the structure: see sb. do sth.. However, when we see part of an action or when the action is in progress, we use the structure like this: see sb. doing sth.
