In English grammar, demonstrative adjectives are used to point out specific things. They are helpful in indicating whether the noun they are related to is singular or plural, and whether it is near or far in distance or time.
Let's look at how to fill in the blanks for the given sentences:
I will not eat these sandwiches.
Use 'these' instead of 'this' because 'sandwiches' is plural and likely close to the speaker in context.
Do you know that man over there?
Use 'that' because 'man' is singular and 'over there' suggests he is further away from the speaker.
These boys broke the glass window.
Use 'these' because 'boys' is plural and suggests they are near, either in context or recently referenced.
Those children are playing in the rain.
Use 'those' because 'children' is plural and they are 'playing in the rain', suggesting they might be at a distance from the speaker.
Parth cannot wear these trousers any longer.
Use 'these' because 'trousers' is a plural noun, even though it's a single garment, indicating a close reference.
Demonstrative adjectives are words like 'this,' 'that,' 'these,' and 'those' that help specify nouns based on distance and number. In the sentences provided, the correct choices are 'these,' 'that,' 'those,' 'those,' and 'these' respectively. Understanding the context of the nouns helps in making the right choices for demonstrative adjectives.
