Appreciation of Language:
NOTE: Explain to the students that many words in English have many corresponding
forms and they are all connected in meaning but used differently as they form words
that belong to different parts of speech.
In this case,"pollute" is a verb and it forms "pollution" – a noun, "polluter" – a noun
that describes the person doing the action "polluted" – a verb in the past tense, and
"polluting" – a verb in the progressive form.

6. Time for a Joke (page 137)
Have students read and explain the joke.
Appreciation of culture and language
NOTE: Understanding a joke in a second language is always

In this case, the joke is based on understanding the language
and the use of the words ‘side’ and ‘outside’ as opposed to
‘left and right’ or ‘top and bottom’.
