Ask some students to say something about Tina and the stories happened on April Fool’s Day. Encourage them to use the Past Perfect Tense.
2. Check the homework by asking some students to share the sentences they made with the verbs with the class.
Step 2 1a
This activity reviews vocabulary and introduces new vocabulary which can be used to talk about inventions.
Read the inventions to the students.
Call the students’ attention to the five pictures, Tell the students that all of these things were invented in the last 150 years.
Point to each picture and let the students tell what it is.
Write the names of the five inventions on the blackboard.
computer, car, calculator, telephone, TV set
Have several different students guess and write the dates on the board.
Ask the class to repeat the questions and answers like this.
T: When was the computer invented?
Class repeat.
SS: When was the computer invented?
T: Good. Now Tom, what is your guess?
S1: 1965.
T: OK. Tom, repeat after me. The computer was invented in 1965.
T: Class, please repeat.
SS: The computer was invented in 1965.
Repeat the process with several different inventions.
Tell the children that they will find out the real dates after they complete the lesson.
After that, ask the students the questions below:
Questions:
1. Which one do you think is the oldest?
2. Which one is the newest?
3. Which one do you think is the oldest or the first invention?
4. Which one is the newest or last invention?
Ask different students to answer the questions.
Have the students look at the example conversation in the box. Ask two students to read this conversation to the class.
A: I think the telephone was invented before the car.
B: Well, I think the telephone was invented after the car.
Read the instructions again to the students. Remind them to remember the inventions from first to last.
Then have the students talk about the five inventions in groups of four, using the sample conversation as a model.
Ask several groups to tell the class their answers. The rest of the class listen to them and show they have different answers by raising their hands.
In the next activity you will find out the real dates.
Step 3 1b
This activity gives students practice in understanding the target language in spoken conversation.
Get the whole class to read the instruction together.
Call the students’ attention to the five inventions in the picture. Ask five students to say the names of them.
Then ask them to see the five dates with a blank line in front of each.
We’ll listen to a girl and a woman talking about the five inventions. They will talk about when they were invented. Listen carefully and match the inventions and the dates. Write the correct letter in front of each date as the sample given. Ask them to have a look at the sample answer. Tell them the answer in front of 1876 is d. That means that the telephone, which is letter d, was invented in 1876.
Play the recording the first time. The students only listen and try to catch the main idea.
Play the recording a second time. Let the students match the inventions and the dates.
Check the answers by asking several to say the answers to the class.
If some of the answers are hard to get for the children, tell them not to worry and they will make it next.
Then play the recording again. Pause after each sentence and let the students repeat.
For some difficult sentences, get the students to repeat several times. Be sure that they make everything clear.

Call the students’ attention to the example in the box. Ask a pair of the students to read this conversation to the class.
SA: When was the telephone invented?
SB: I think it was invented in 1876.
Write the conversation on the blackboard.
Then get the students to practice in pairs, using the information in Activity 1b. Tell them to do it like this:
Student A, covers the dates. Students B, asks Student A when the things in the picture above were invented. Then change roles and practice again.
Ask several pairs to share their conversations with the class.

1. The article is about the invention of tea.
2. It was invented over three thousand years ago.

Step 3 3b
This activity provides reading and writing practice using the target language.
Ask the whole class to read the instructions together.
Then show a real flying disk to the children and tell the children the name of the toy is a flying disk in English.
You’ll have to write an article using the notes in the box. The article will tell how the flying disk was invented. At first, let’s go over the notes in the box. There are some new words.
Go over the notes with the class. Point out the new words. Teach them to read and do some explanation at the same time. Make sure that all the students make everything in the notes clear.
Then ask the children to look at the contents and the picture in the right box.
Look at the picture in the right box. We can see a flying plate in the animal’s mouth. And the title of the article has been given--From pie plate to flying disk. Also the first sentence has already been given to us. Let’s read the title and the first sentence together now.
Have the students read together.
Find out how the writer combined the phrases in the notes into one sentence and try to say out the next sentence.
Let them think for a while. Then ask several ones to say their sentences to the class. The sentences will vary, but have to be correct and meaningful.
For example, someone may say like this:
The original flying disk was really a metal pie plate from a bakery in Bridgeport, Connecticut.
Then ask the children to make their own sentences with the notes given and note to say out the sentences in proper order to be an article. Let them work in pairs, listen to and help each other.
After that, get the students to write their own articles. More around the classroom while they are writing, checking progress and offering help as necessary.
Next, ask several students to share their articles with the class.
Correct the mistakes they may have made
If time permits, get the students to work in pairs and check each other’s article.
Sample writing:
The flying disk is a toy which was invented by a group of college students. It was invented in the1950s.
In fact, the students didn’t invent it.
They just discovered it. The original flying disk was really a metal pie plate from a bakery named Bridgeport in Connecticut. The students there liked to eat the bakery’s pies. And then they threw the pie plates around. A company began making plastic disk. Now there are flying disk clubs, a flying disk magazine, and even a national flying disk festival in September.
Don’t you think it’s amazing that all this started from a pie plate?
Step 4 4a
This activity provides reading and writing practice using the target language.
Read the instructions to the students.
There is always something that we hate doing. For example, I hate cleaning the blackboard. What about you?
Then ask some children to say the things they don’t like doing to the class.
After that, continue saying. Now please think of an invention that could help you.
For me, I want to invent a self-cleaning board with something like a car’s windsheld wipers. Then I would never need to clean the blackboard myself. What about you?
Get the students to discuss the things they hate doing and the inventions that could help them. Let them work in pairs.
Then call the children’s attention to the chart on the right.
Get them to look at the sample answer and try to complete the chart first.
Ask some children to give their answers to the blanks of use and price. Such as,
Use: to write tests instead of me by listening to me
Price: one hundred yuan per pen
Then get the students to fill in the chart with the details of their own inventions.
Don’t review the task. It will be done in the next task.
Step 5 4b
This activity provides listening and speaking practice using the target language.
Read the instructions to the class.
Get the students to ask and answer questions about their inventions in pairs first.
Ask a pair to make a model conversation before the whole begin practicing. For example, they may say like,
( B—Businessperson , I—Inventor)
B: Excuse me, what invention was invented by you?
I: A special pen.
B: What is it used for?
I: It is used for writing tests. While the test is on, the pen can write tests instead of persons according to what its owner tells it.
B: Wow, that’s great. How much would you like to sell it for?
I: I hope I can get 100 yuan.
B: OK. I will try to sell it to the class.
After that, let the students work in pairs, Imagine one is a businessperson and the other is an inventor while they are practicing.
Ask several pairs to share their conversations with the class.
Then tell them to look at the model conversation in the box.
Ask one student to read the conversation below to the class:
A: This special pen was invented by Zheng Jie. It has three colours and it is used for writing tests. It can listen and write while the test is on. It is 100 yuan.
Is anyone interested in it?
Then ask some others to share their presentations with the class.
They have to state the reason for buying them.
Then the class votes for the most popular invention they want to buy.
Step 6 Self check
1.Filling blank On page 73 is a box with 4 sentences. Read the sentences and fill in the blank with a correct word. Now you are asked to make your own sentences with each of the four words.
2 Writing about inventions on page 73,check.
3. Just for fun!Look at the pictures below and tell about what you see. Use as many examples of passive voice (questions and statements) as possible.
Step 7 Summary
