Question

Fill in the blank with a suitable preposition:
I always Lie down_________ a swim.
A. by
B. with
C. on
D. after

Answer 1

Hint:Prepositions and postpositions are a class of terms used to convey spatial or temporal relationships or to mark different semantic functions, called ad positions.

Complete answer:
Prepositions are phrases that demonstrate associations with the other phrases in the sentence. To denote time in a sentence, prepositions of time are used. Let’s look at the use of different choices in the option as a time preposition:
A. By: Meaning at or before a certain time and not after it,
B. With: not used as a time preposition
C. On: to refer to the days / time period
D. After: means "A phase after than"
Upon reading the phrase in the query, we understand that the speaker conveys that after a swim, he / she always lies down. So the necessary preposition here is" after. The proper complete sentence, therefore, is: I always lie down AFTER a swim.

Additional information:
Prepositions show how two words are linked. Lots of prepositions (e.g., "on," "in," "near," "behind," "under," "inside") tell us where things are relative to each other. For example: The cat sat on the mat.
Object of a Preposition- The word (or phrase) that follows a preposition is called the object of a preposition. If there is a preposition, there will always be an object of the preposition. A preposition cannot exist by itself.
Prepositional phrases- A prepositional phrase is made up (including any modifiers) of a preposition and the object of the preposition. There are very prominent prepositional sentences. They act either as adjectives or adverbs.

Hence the correct answer is option ‘D’

Note:Preposition is used to link the words of a sentence. The use of prepositions is considered very important in English grammar. For the correct use of prepositions, you have to strengthen your vocabulary and also study the rules related to prepositions.
