Incomplete question. I inferred you meant knowing which word (s) in the sentence has a preposition.
Step-by-step explanation:
Remember, a preposition is a word or group of words used in a sentence to show time, place, or location/position. It is usually placed before a noun, pronoun, or noun phrase. For example, words like "in," "on," "of," and "to," "last," are commonly used.
The preposition in the sentence is underlined and bolded, where there is no preposition (#NA ) is written:
- Vimalwill not post many letters to his friend.
- Did you draw a picture last week?
- He hurt me a lot in 2019.
- Will she bring a camera tomorrow?
- They painted a beautiful car last year.
- Shall I eat this mango? (#NA )
- My mother did not punish me. (#NA )
- Ravi sang many songs last month. (#NA )
