Choose the sentence that correctly uses the Present Perfect Continuous...
Answer:
The sentence that correctly uses the Present Perfect Continuous/Progressive Tense with a specific duration is option 'D': "She has been studying all night for the exam."
Explanation:
The Present Perfect Continuous/Progressive Tense is used to describe an action that started in the past, is still happening at the present moment, and may continue into the future. It emphasizes the duration or ongoing nature of an action.
Let's analyze each option to understand why the correct answer is option 'D':
a) They have been waiting for the bus yesterday:
- This sentence is incorrect because the phrase "yesterday" indicates a specific past time that has already ended. The Present Perfect Continuous Tense is used to talk about actions that started in the past and are still happening, but it does not specify a specific time in the past.
b) He has been working since he graduated:
- This sentence is correct. It uses the Present Perfect Continuous Tense to show that the action of working started in the past (when he graduated) and is still happening at the present moment. It implies that he has been continuously working since his graduation.
c) We have been living in this neighborhood since a year:
- This sentence is incorrect because the phrase "since a year" is grammatically incorrect. The correct phrase should be "for a year" to indicate a specific duration. Additionally, the use of the Present Perfect Continuous Tense implies that the action is still ongoing, but the sentence does not specify whether they are still living in the neighborhood.
d) She has been studying all night for the exam:
- This sentence is correct. It uses the Present Perfect Continuous Tense to show that the action of studying started in the past (last night) and is still happening at the present moment. It emphasizes the duration of studying all night for the exam.
Therefore, the correct answer is option 'D': "She has been studying all night for the exam." This sentence correctly uses the Present Perfect Continuous Tense with a specific duration.
