Which sentence correctly uses the present perfect tense to express a c...
Understanding Present Perfect Tense
The present perfect tense is used to express actions or situations that have relevance to the present moment. It often indicates a change or development over time.
Correct Option: A
- "She has grown a lot since last year."
- This sentence uses the present perfect tense correctly.
- The phrase "has grown" indicates an ongoing change that started in the past and continues to the present.
- The use of "since last year" reinforces the idea that the change (growth) has been observed over a specific period.
Why Other Options are Incorrect
Option B:
- "He has learned English when he was a child."
- The phrase "when he was a child" specifies a definite time in the past, which does not fit the present perfect tense.
Option C:
- "They have moved to New York in 2010."
- The phrase "in 2010" indicates a specific time in the past, which contradicts the present perfect use that focuses on an indefinite time.
Option D:
- "I have bought a car last month."
- "Last month" is also a specific time frame. The correct form should use the simple past tense instead.
Conclusion
Option A is the only sentence that appropriately uses the present perfect tense to convey a change over time, making it the correct choice.
