Practise the sentences in the textbook from the end to the beginning

II.Grammar: The passive voice
1.Formation:
The classroom has been cleaned
The window was broken
=> Be + past participle
The passive voice can be used in different tenses.
e.g: The passive forms of “break” on the wallchart.
2. Usage: The passive voice is used in 3 ways:
When we don’t want to take responsibility for something.
e.g: The house will be painted soon.
When we want to focus on a happenning, not who or what did it.
e.g: The flat has been broken into.
When we want to avoid using subjects like “one, someone, they…..”.
e.g: The apple was thrown away.

However, if we want to mention to whom or what did the action, we can use “ Be + past participle + by O”.
e.g: The letter was written by my brother.
This picture is being drawn by him.
