Explanation

"I congratulated him on his success."

میں نے اسے اس کی کامیابی پر مبارکباد دی۔

The preposition "on" is commonly used when congratulating someone for an achievement or event.

Explanation

Correct Narration Change:

The original sentence ("Please don't go away," he said to me.) is an implored request (polite command).

In indirect speech, "said to" changes to "requested" (for polite pleas) or "told" (neutral).

"Don’t go away" becomes "not to go away" (infinitive structure in reported speech).

Explanation

Correct Passive Voice Conversion:

The original sentence ("Have you finished your job?") is in the active voice (Present Perfect Tense).

Its passive form follows the structure: "Has/Have + subject + been + past participle + by + agent?"

Thus, it becomes: "Has your job been finished by you?"

Explanation

This is an imperative sentence; passive voice of "Help him" is formed using "Let + object + be + past participle".

So, "Help him" becomes "Let him be helped." in passive voice.

Explanation

The correct phrase is "across the street", meaning on the opposite side.

Across can be used as a preposition.

It indicates movement or position from one side to the other of something with boundaries, like a road, river, or room.
