Step I Revision

Check the students' homework and ask the student to retell the text.

A sample retelling version:

My mother lived in the countryside and was upset about the snakes in the yard. She wanted me to help her get rid of them. How to catch these snakes without hurting them?

First I checked if there were produc5ts that might help, but there seemed to be only some powders. So I had to find out a new way. I began researching the habits of snakes. Then I decided on three possible ways and used the last one: to cool the snakes and catch them.

I bought an ice-cream maker and took the owl from the machine. I put some jelly on the outside and inside walls of the bowl. Then I put the bowl into the freezer and waited. At the same time, I prepared some ice-cubes.

In the following two days, I tried to catch them. But I failed.

Then I decided to use a net to catch the snakes after they became passive. This time, I made it. My friends and relations pressed me to send my invention to the patent office to get recognition. So I filled the form and filed may patent application with the patent office and waited for the result.
