If the subject does something, the verb is active:
I spilled chocolate sauce on my new suit.
If the subject has something done to it, the verb is passive:
Chocolate sauce was spilled on my new suit.
Notice that these two sentences give approximately the same information, except that the passive doesn't reveal who spilled the chocolate sauce.
English teachers often seem to assume that the passive should never be used. In fact the passive can be very useful. The subject of a sentence gets more emphasis than the object. By choosing to use the active or passive form, we can emphasize words or subordinate them or even conceal them.
Here are some examples of situations where the passive can be used to advantage:
Having said all this, we must say that generally active verbs make writing more forceful and succinct. However, passive verbs do have their place.
