Read the theory. Then rewrite sentences 1 -9 in the passive. Omit the agent where necessary.
We use by + agent to say who or what carries out the action. We use with + instrument/material/ ingredient to say what the agent used. The cake was made by Sally. It was made with chocolate fudge The agent is often omitted in passive sentences when the subject of the active sentence is: people, one, someone, they, etc. Someone stole Tom's car. Tom's car was stolen. The agent is not omitted when it is a specific or important person or when it is essential to the meaning of the sentence. The government has passed a new law. A new law has been passed by the government.
