Select the most appropriate option to improve the bold part of the sentence.
It is high time you leave the room.
Show answer & explanation
Correct answer: C
Explanation
When phrases like "It is time," "It is high time," or "It is about time" are followed by a subject (in this case, "you"), the verb must be in the simple past tense.
Meaning: Even though the past tense is used, the sentence refers to the present or future. It suggests that an action should have happened already and is now overdue.
The most appropriate option to improve the bold part of the sentence is “left the room”.
The corrected sentence is: "It is high time you left the room."
