This worksheet helps students practice grammar by turning statements into questions using helping verbs like "is," "are," and "have."

The task involves transforming the given sentences into questions by adding a helping verb. Helping verbs (also known as auxiliary verbs) include words like be, do, and have. These verbs help express tense, mood, or voice in a sentence.

#### 1. She is singing a song.
- Original: She is singing a song.
- Question: Is she singing a song?

#### 2. They were playing soccer.
- Original: They were playing soccer.

#### 3. I have been studying for my test.
- Original: I have been studying for my test.
- Question: Have I been studying for my test?

#### 4. He has been reading a book.
- Original: He has been reading a book.

#### 5. We are having a picnic.
- Original: We are having a picnic.
- Question: Are we having a picnic?

#### 6. They will be arriving soon.
- Original: They will be arriving soon.
- Question: Will they be arriving soon?

#### 7. She can dance gracefully.
- Original: She can dance gracefully.
- Question: Can she dance gracefully?

Explanation:

To form questions using helping verbs:
1. Identify the helping verb in the sentence (e.g., is, were, have, has, are, will, can).
2. Move the helping verb to the beginning of the sentence.
3. Rearrange the remaining parts of the sentence to maintain proper grammar.

For example:
- In "She is singing a song," the helping verb is is. Moving it to the front forms the question: Is she singing a song?
- In "They were playing soccer," the helping verb is were. Moving it to the front forms the question: Were they playing soccer?

This process ensures that the sentences are transformed into questions while maintaining their meaning and grammatical structure.

Final Answer:

1. Is she singing a song?
2. Were they playing soccer?
3. Have I been studying for my test?
4. Has he been reading a book?
5. Are we having a picnic?
6. Will they be arriving soon?
7. Can she dance gracefully?
