When we say what people or things do, we use active verbs. (For example built, speak, is repairing, will change.)
When we say what happens to people or things — what is done to them
— we use passive verbs. (For example was built, is spoken, is being repaired, will be changed.)
The object of an active verb corresponds to the subject of a passive verb.
PASSIVE: Active or passive?
We often prefer to begin a sentence with something that is already known, and to put the 'news' at the end. Compare:
Your little boy broke my kitchen window this morning.
That window was broken by your little boy.
In the first sentence, the hearer does not know about the broken window. So the speaker starts with the little boy, and puts the 'news' — the window — at the end. In the second sentence, the hearer knows about the window, but does not know who broke it. By using a passive structure, we can again put the 'news' at the end.
'John's writing a play. ' I didn't know that.'
'This play was written by Marlowe. ' 'Was it? I didn't know that. ' To make passive verb forms, we use the auxiliary be. .
Benefits of Mushroom
Mushrooms possess antiageing properties. Kojic acid is often used in creams, lotions and serums as a remedy for signs of ageing such as liver spots, age spots, discoloration and uneven skin tone caused by photo damage. Mushrooms enhance the natural defenses of the skin and improve its appearance by making it healthy.
