Say you have a sentence:
The food is being processed in a factory.
The food is processed in a factory.
Both of them sounds right to me. Which one is grammatically correct? When would you use is being? Can anyone gives some examples? Thanks.
Both are correct. The first sentence is ‘present tense’, in that the word choice of ‘being’ means it is currently happening at this time. The second sentence is without a tense, and so it is more of a statement by itself. Both sentences sound like they are answers to a question, though.
