The correct option to complete the sentence "Isn't it high time you .... your office?" is
D. left.
Explanation of the Correct Answer
- Understanding the Phrase "High Time":
- The expression "high time" is used to indicate that something should have been done a long time ago. It implies urgency and a sense of overdue action.
-
When we use "high time," it is typically followed by a verb in the past tense, even though we are referring to a present situation. This is a grammatical structure that emphasizes the need for action.
-
Analyzing the Options:
- A. are leaving: This option uses the present continuous tense, which indicates an action that is currently happening. However, "high time" suggests that the action should have already occurred, making this option incorrect.
- B. do leave: This option uses the base form of the verb "leave" with "do," which is not appropriate in this context. "Do" is often used for emphasis or in questions, but it does not fit with the expression "high time."
- C. leave: This option uses the base form of the verb "leave." While it might seem plausible, it does not align with the grammatical structure that follows "high time," which requires a past tense verb.
- D. left: This is the correct option. It uses the past tense of the verb "leave," which is appropriate after "high time." The sentence implies that it is overdue for the person to have left their office.
Why the Other Options are Incorrect
- A. are leaving: Incorrect because it suggests an ongoing action rather than something that should have been completed already.
- B. do leave: Incorrect as it does not fit the context of urgency implied by "high time." It also does not follow the grammatical structure required.
- C. leave: While it is the base form of the verb, it does not conform to the expected past tense structure that follows "high time."
