Paper: PROFESSIONAL ENGLISH
Introduction
Grammar plays a vital role in effective communication. Question forms help us gather information, while subject–verb agreement ensures clarity and correctness in sentences. Mastery of these concepts is essential for academic, professional, and everyday communication.
I. Question Types in English
Questions are sentences used to ask for information. In English, questions are broadly classified into Wh-questions, Yes/No questions, and Tag questions.
1. Wh-Questions
Wh-questions begin with question words like What, When, Where, Who, Whom, Which, Why, and How. These questions demand detailed answers.
Structure:
Wh-word + auxiliary verb + subject + main verb
Examples:
-
What is your profession?
-
Where do you work?
-
Why did you choose engineering?
-
How does this machine function?
Uses:
-
To collect specific information
-
Commonly used in interviews, discussions, and examinations
2. Yes/No Questions
Yes/No questions can be answered with “Yes” or “No.” They usually begin with an auxiliary verb.
Structure:
Auxiliary verb + subject + main verb
Examples:
-
Are you ready for the presentation?
-
Do you understand the instructions?
-
Is the project completed?
-
Have you submitted the report?
Uses:
-
Used in confirmations and quick responses
-
Common in formal and informal conversations
3. Tag Questions
Tag questions are short questions added at the end of statements to confirm or seek agreement.
Structure:
Statement + comma + auxiliary verb (opposite form) + pronoun
Examples:
-
You are a student, aren’t you?
-
She completed the task, didn’t she?
-
They are coming today, aren’t they?

He hasn’t finished yet, has he?
Uses:
-
To confirm information

To make conversations polite and interactive
II. Subject–Verb Agreement

3. Collective Nouns
Collective nouns take a singular verb when referring to a group as a unit.

-

4. Indefinite Pronouns
Words like everyone, someone, each, anybody take singular verbs.
-
Everyone is present today.
-

5. Compound Subjects
-

-
6. Subjects with “Each” and “Every”
