Passive Sentences

Active sentence is the sentence that the subject of the sentence is an act of the perpetrator, while the passive sentence is the sentence that the subject is not theperpetrators of an act. The subject is the recipient of the result of an action.

Compare the following sentences:

     * Active: Susi typing this letter yesterday
     * Passive: This letter was typed by Susie yesterday
     * Active: My cat kills a mouse
     * Passive: A rat was killed by my cat

Note:
Use passive voice if the perpetrator acts not so important.

Example:

     * The tower was built in 1955

If we need to mention who the perpetrators of an act, use the word by (by)

Example:

     * The tower has been built by local governments in 1955

The general formula to form a passive sentence

     * Active: S + Verb (Word Work) + Object + etc.
     * Passive: Object + to be + Verb 3 (Work Words Form III) (+ by the subject) + etc.

Things that need to be known and remembered
