Complete Answer with Explanation (200–350 words)

a) Combining Sentences with "Who"

The original sentences are:

  • A doctor is a person.
  • He treats patients.

To combine them using "who", we identify the subject (a doctor) and the additional information (treats patients). The relative pronoun "who" replaces "he" and connects the two clauses.

Final Answer: A doctor is a person who treats patients.

Why?

  • "Who" refers to the subject (a doctor) and introduces the additional clause (treats patients).
  • The sentence remains grammatically correct and concise.

b) Changing to Passive Voice

The original sentence:

  • They are building a new bridge.

Step-by-Step Conversion:

  1. Identify the object (a new bridge)—this becomes the subject in passive voice.
  2. The verb (are building) changes to "is being built" (present continuous passive).
  3. The subject (they) is omitted (unless emphasis is needed).

Final Answer: A new bridge is being built (by them).

Why?

  • The passive voice shifts focus from the doer (they) to the action (building).
  • The tense remains present continuous (are → is being).

c) Correct Verb Form in Conditional Sentence

The original sentence:

  • If I (be) you, I would not tell a lie.

Key Rule:

  • In unreal conditions (hypothetical situations), we use "were" (not "was" or "am").
  • The structure is: If + subject + were + ..., subject + would + base verb.

Final Answer: If I were you, I would not tell a lie.

Why?

  • "Were" is used for all subjects (I/he/she/we/they) in unreal conditions.
  • The auxiliary verb "would" indicates a hypothetical action (not tell a lie).

Note for Students:

  • For relative pronouns (who/which/that), ensure the clause provides extra information.
  • In passive voice, the object becomes the subject, and the verb is adjusted accordingly.
  • In conditional sentences, use "were" for all subjects in unreal conditions.
