Let's solve this grammar worksheet step by step. The task is to
choose the correct subject from the given list for each sentence. The word choices are:
>
Cats / study / bag / eat / baby / birds
Note: Some of these words are
verbs (study, eat), and others are
nouns (cats, bag, baby, birds). Since we're looking for
subjects, we need to pick
nouns that make sense in each sentence.
---
Sentence 1:
"The _________ smiled."
- "Smiled" is a past tense verb.
- We need a
singular noun because the verb is singular ("smiled").
- Let’s check possible options:
-
Cats → plural → doesn't match "smiled"
-
Study → not a person/thing that can smile
-
Bag → doesn’t smile
-
Eat → verb, not a subject
-
Baby → singular, can smile
✔
-
Birds → plural, doesn’t match "smiled"
✔ Correct answer: baby
>
The baby smiled.
---
Sentence 2:
"The lovely _________ are singing."
- "Are singing" = plural verb → needs a
plural subject
- Possible nouns:
cats,
birds,
baby (singular),
bag (singular)
- Only
cats and
birds are plural nouns
- "Lovely cats" or "lovely birds"? Both work grammatically, but
birds are commonly described as “lovely” when singing
But let’s see: both
cats and
birds could fit. But the verb is
are singing, which is more natural with
birds than cats (since birds sing, cats don’t usually “sing”).
✔ Best choice: birds
>
The lovely birds are singing.
---
Sentence 3:
"My _________ is on the desk."
- Verb: "is" → singular
- So we need a
singular noun
- Options:
-
Bag → fits perfectly: "My bag is on the desk"
✔
-
Study → could be a place, but "my study is on the desk" doesn't make sense
-
Baby → "My baby is on the desk"? Unlikely
- Others are plural or verbs
✔ Correct answer: bag
>
My bag is on the desk.
---
Sentence 4:
"Hessa’s _________ drink milk."
- Verb: "drink" → plural form → needs a
plural subject
- Plural nouns:
cats,
birds
- "Hessa’s cats drink milk" → makes sense
✔
- "Hessa’s birds drink milk" → birds don’t typically drink milk; unusual
- Also,
"study" and
"eat" are not subjects
-
"baby" is singular → doesn't match "drink"
✔ Best choice: cats
>
Hessa’s cats drink milk.
---
Final Answers:
1. The
baby smiled.
2. The lovely
birds are singing.
3. My
bag is on the desk.
4. Hessa’s
cats drink milk.
