guys and teachers please i have got confused , i don’t know how can i use " as "
but honestly i know some sentence that i should use “as” for example :
write something as long as you can = short example ><"
Are there any specific time ?!
Your question is not clear to me. ‘As long as you can’ is all right, but the rest of your example is not. Try these:
Write as long an essay as you can.
Hold your breath as long as you can.
I am not as strong as Herakles.
A banana is as yellow as a grapefruit.
He is dressed as a policeman.
I like you as you are.
There are two main uses of ‘as’. It is used for comparisons - Charlie and George are the same height = Charlie is as tall as George/George is as tall as Charlie.
It can also be used to suggest ‘when’ (a) or ‘because’ (b) at the start of sentences -
(a) It started to rain as I was driving through the town.
