Task: write the sentences in passive voice using the prompts: For example: The Magic flute/compose/Mozart The Magic Flute was composed by Mozart. 1) America/discover/Christopher Columbus (past simple) 2) English / speak / all over the world (present simple) 3) The room / clean/ every day (present simple) 4) The telephone/invent/Alexander Bell (past simple)

1) America was discovered by Christopher Columbus.
2) English is spoken all over the world.
3) The room is cleaned every day.
4) The telephone was invented by Alexander Bell.

Explanation:

1) The passive voice is used to emphasize the action being done to the subject, rather than the subject performing the action. In this case, the action is "discover" and the subject is "America." So, we use the passive voice and say "America was discovered by Christopher Columbus."

2) Similarly, we want to emphasize that English is spoken by people all over the world. So, we use the passive voice and say "English is spoken all over the world."

3) In this sentence, the subject "the room" receives the action of "clean" every day. So, we use the passive voice and say "The room is cleaned every day."

4) Lastly, the action of "invent" is done to the subject "the telephone" by Alexander Bell. So, we use the passive voice and say "The telephone was invented by Alexander Bell."

By using the passive voice, we can focus on the subject receiving the action rather than the subject performing the action. This helps to vary sentence structure and make our writing more interesting.
