Present Continuous or Present Perfect Continuous?
Answers
Answer:
ANSWER
Option B is correct. The present perfect tense is written as: have/has + past participle of the verb. In the given sentence, "received" is the simple past tense of the infinitive "to receive". Moreover, the sentence is in first person singular which means that "have" must be used here. Moreover, the present perfect cannot be used when you are being specific about when the action/event happened (a week ago). Thus, the resulting sentence is: I have received his letter.
Option A is incorrect as the present perfect cannot be used when you are being specific about when the action happened; that the letter was received a week ago.
Option C is incorrect as it is in present simple.
Option D is incorrect as the use of "has" is incorrect. "Has" cannot be used when the sentence is in first person singular.
