Weclome, melone.
The
simple past is a verb tense. It expresses an action that happened in the past, like this,
[1] Yesterday, I
ate cake.
The passive is when
the object of the verb is moved to the front of the sentence, like this,
[2] Yesterday,
cake was eaten by me.
A
passive verb is formed by using the verb BE (e.g., is, am, was, were, etc) and the past participle of the verb. In our example [2] the passive verb is "
was eaten".
Here's the basic information for the verb To eat:
Present Tense: eat
Past Tense: ate
Past participle: eaten
Present participle: eating
When you learn a verb, any verb, you should learn its four forms: its present tense form, its past tense form, its past participle, and its present participle.
Hope that helps. ;)
