Step Ⅲ 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.
