you use the lights to see and brighten a room. and with out them you cant see. you need a toothbrush to clean your teeth with out it stinky breath. shower to wash ya self and without it you stink. toaster to toast stuff without it nothing is toasted. and the refrigerator to keep stuff cold without it everything goes bad

the present continuous is a verb tense which is mainly used to indicates that an action is in progress at the moment of speaking.  

it is formed using: person + verb to be (am/is/are) +verb + - ing form  

example: i am studying at this moment .

in addition, the present continuous is also used in order to express things that will or will not happen in the near future.

example: i am having dinner with some friends tonight.

the speaker sometimes   uses it   to express that an action is repeated and it causes irritation on the part of the speaker

example: my sister is constantly complaining about everything.
