Grammar practice worksheet for beginners focusing on the verb "to be" in singular and plural forms.

Let's solve this grammar worksheet step by step. The task is to fill in the blanks with the correct form of the verb "to be" — either am, is, are, or was/were (for past tense), depending on the subject and context.

---

🔹 Key Rules for "To Be":

- Singular subjects:
- I → am
- He/She/It → is
- A person/place/thing → is
- Plural subjects:
- You/We/They → are
- Multiple people/things → are
- Past tense:
- Was → singular (he, she, it)
- Were → plural (they, we, you)

Also, note that "be" can also be used in present continuous or passive voice, but here it’s mostly about state of being.

Let’s go through each sentence and determine the correct form:

---

✔ Singular Form (I, He, She, It)

1. My cat ___ black and white.
→ "cat" = singular → is
✔️ is

2. He ___ inside the house.
→ "He" → is
✔️ is

3. Mum and Dad ___ away.
→ "Mum and Dad" = two people → plural → are
✔️ are

4. Grandma ___ here.
→ "Grandma" = singular → is
✔️ is

5. Grass ___ green.
→ "Grass" is uncountable noun, treated as singular → is
✔️ is

6. The sun ___ yellow.
→ "Sun" = singular → is
✔️ is

7. Is the sea blue?
→ Already has auxiliary "is", so no change needed.
✔️ is

8. An animal.
→ "A horse" = singular → is
✔️ is

9. Canada ___ a city in the USA.
→ Wait: Canada is not a city. This is a false statement, but grammatically:
"Canada" = country → singular → is
But factually incorrect. Still, grammatically:
✔️ is *(though the sentence is false)*

10. The bike ___ from my father.
→ "bike" = singular → is
✔️ is

11. The poster ___ from John.
→ "poster" = singular → is
✔️ is

12. The plane ___ late.
→ "plane" = singular → is
✔️ is

13. The people ___ noisy.
→ "people" = plural → are
✔️ are

14. Nobody ___ here.
→ "Nobody" is singular → is
✔️ is

15. John, Mike and Bo ___ sick.
→ Three people → plural → are
✔️ are

16. An egg ___ white and yellow.
→ "egg" = singular → is
✔️ is

17. Rome ___ the capital city of Italy.
→ "Rome" = singular → is
✔️ is

18. Beans ___ green.
→ "Beans" = plural → are
✔️ are

19. This ___ healthy.
→ "This" = singular → is
✔️ is

20. I ___ hungry.
→ "I" → am
✔️ am

21. Sylvia ___ in love with Bob.
→ "Sylvia" = singular → is
✔️ is

22. The queen ___ fat.
→ "queen" = singular → is
✔️ is

23. The king ___ strong.
→ "king" = singular → is
✔️ is

24. You ___ brave.
→ "You" → are
✔️ are

25. He ___ mad.
→ "He" → is
✔️ is

26. Ice-cream ___ hot.
→ "Ice-cream" = uncountable, singular → is
✔️ is

27. Coffee ___ cold.
→ "Coffee" = uncountable, singular → is
✔️ is

28. Pancakes ___ good.
→ "Pancakes" = plural → are
✔️ are

29. It ___ a super job!
→ "It" → is
✔️ is

30. I ___ a super job!
→ "I" → have? Wait — this is awkward.
But it says: “I ___ a super job!”
That should be “I have”, not “to be”.
But the exercise asks for "to be".
So likely typo. Maybe meant: “It is a super job!”
But as written: “I ___ a super job!” → doesn’t fit “to be”
→ Possibly “I am”? But “I am a super job” is nonsense.
So maybe “I have” is intended, but since it's a "to be" exercise, perhaps it's “I am” followed by something else?
Let’s assume typo.
Alternatively, if it's “I am a superhero”, but here it’s “job”.
Probably best to leave as is — but doesn't make sense.
→ Likely error in worksheet.
But if forced: perhaps “I am”?
But “I am a super job” is incorrect.
So perhaps the intended sentence was: “It is a super job!”
But since it says “I”, maybe it's “I am doing a super job”? Again, not “to be” alone.
→ We’ll skip or mark as not applicable.
But let’s assume it's a mistake and move on.
For now: ✘ No valid “to be” form — possibly typo.

✔ Plural Form (You, We, They, etc.)

Now the second column:

31. Scott ___ a boy.
→ "Scott" = singular → is
✔️ is

32. He ___ seven years old.
→ "He" → is
✔️ is

33. Maria ___ a girl.
→ "Maria" → is
✔️ is

34. She ___ Scott’s sister.
→ "She" → is
✔️ is

35. You ___ in my house.
→ "You" → are
✔️ are

36. I like it when you ___ here.
→ "you" → are
✔️ are

37. We ___ a good footballer.
→ "We" → are
→ But "footballer" is singular → contradiction
→ Should be: “We are good footballers.”
→ But as written: “a good footballer” → implies one person
→ So probably typo — should be “I am” or “He is”
→ But “We” + “a footballer” → mismatch
→ So likely error.
→ But grammatically: are
✔️ are *(even though semantically odd)*

38. They ___ from Germany.
→ "They" → are
✔️ are

39. We ___ from Denmark.
→ "We" → are
✔️ are

40. It ___ hot today.

✔️ is

→ "Tinker" = name of dog → singular → is
✔️ is

43. A football ___ often white.
→ "football" = singular → is
✔️ is

44. I ___ my bike.
→ "I" → am
→ But “I am my bike” is nonsense
→ Should be “I have my bike”
→ But again, if using “to be”, maybe “I am riding my bike”
→ But here: “I ___ my bike” → only fits am if metaphorical
→ But unlikely
→ Perhaps typo — maybe “This is my bike”
→ But as written: “I ___ my bike” → am?
→ No, not logical
→ So likely error
→ Best guess: am — but invalid
→ Skip or note error

45. Muzzy ___ a monster.
→ "Muzzy" = singular → is
✔️ is

46. We ___ happy.
→ "We" → are
✔️ are

47. ___ you from America?

✔️ am

- #30: "I ___ a super job!" → Grammatically incorrect; should be “I have a super job.”
- #44: "I ___ my bike." → Doesn’t make sense with “to be”; should be “I have my bike.”
- #37: "We ___ a good footballer." → Should be “I am” or “He is” or “We are good footballers.”

These appear to be typographical or conceptual errors in the worksheet.

✔ Explanation:
We applied the rules of subject-verb agreement with the verb "to be":
- Use is for singular subjects (he, she, it, singular nouns).
- Use are for plural subjects (they, we, you, plural nouns).
- Use am only with I.
- Use was/were for past tense, but none of these sentences require past tense.

Some sentences contain errors in logic or grammar (e.g., "I am my bike"), which may need correction in the original worksheet.
