<span>"Have you ever been taken to the State Fair?" is passive. "</span><span>The team won the state championship." is active. To differentiate is really easy! Passive voice is constructed by using "to be" and past participle (e.g. bought, cost, made, done, etc.) and put enfasis on the action, not on the person who did/does it.</span>
Dear sun, please do not retire. If you retire the earth and the other planets will be frozen! The whole human race would disappear and animals would be to. The whole world depends on you!
