Printable English grammar worksheet featuring four sections of supporting exercises on verbs like am, is, are, do, does, has, and have.

Let's solve each section of this English grammar worksheet step by step and explain the rules behind the answers.

---

A. Complete with: am, are, is

This section tests subject-verb agreement with the verb "to be" (am, is, are).

Rules:
- Use am with I
- Use is with singular subjects (he, she, it, a person, a thing)
- Use are with plural subjects (they, we, you, multiple people/things)

#### Answers:
1. They are my English friends.
→ "They" is plural → use are

2. You are my brother.
→ "You" always takes are

3. The teacher is in the class now.
→ "The teacher" is singular → use is

4. She is tall, thin and beautiful.
→ "She" is singular → use is

5. I am tall and he is short.
→ "I" → am, "he" → is

6. My ball is red and blue.
→ "My ball" is singular → use is

7. Paul and Susan are at home.
→ Two people → plural → are

8. We are intelligent and hard-working.
→ "We" → are

9. I have a red window.
→ Wait! This sentence uses "have", not "be". But the instruction says "Complete with: am, are, is" — so likely a typo. However, since "have" is used, it doesn't fit. Let’s assume it should be “I have” or maybe it was meant to be “It is a red window.” But as written, it's incorrect for "am/is/are".

Actually, rechecking: the sentence is “I …… a red window.” – this cannot be completed with "am/is/are" because it needs a verb like "have" or "has". So possibly a mistake in the question.

✔ But if we must use "am/is/are", then:
→ "I am a red window." → illogical.
So probably intended to be "It is a red window" or "I have a red window".

✘ So this sentence might be invalid for this section. Let's skip it or assume it's a typo.

But looking again: perhaps it's meant to be "It is a red window."? But it says "I".

→ Likely a typo. We’ll proceed with what makes sense.

Let's assume it’s "It is a red window." → but it says "I".

Alternatively, maybe it's "I see a red window"?

Since we can’t fix it, let's just note: This sentence does not make sense with "am/is/are".

So we'll skip it or assume it's misprinted.

10. My little sister is at school right now.
→ "My little sister" is singular → is

✔ Final Answers for A:
1. are
2. are
3. is
4. is
5. am, is
6. is
7. are
8. are
9. ✘ Invalid (should be "have")
10. is

Rule:

2. There are ten children in class.
→ "ten children" = plural → are
