To rewrite the given sentences as per the directions provided:
(i) I have dropped the letter into the letter box. (Present perfect)
- Explanation: In the present perfect tense, we use "have" or "has" with the past participle form of the verb. In this case, "dropped" is the past participle of "drop."
(ii) My grandfather went to bed early. (Simple past)
- Explanation: In the simple past tense, we change the verb form to its past tense. In this sentence, "goes" changes to "went."
(iii) Rajat is running very fast. (Present continuous)
- Explanation: To change to the present continuous tense, we add "is" or "are" (depending on the subject) before the base form of the verb with "-ing." Here, "runs" becomes "is running."
(iv) Mr. Jain will buy a new car. (Simple future)
- Explanation: In the simple future tense, we use "will" before the base form of the verb to indicate a future action. So, "bought" changes to "will buy."
(v) Children were playing in the field. (Past continuous)
- Explanation: The past continuous tense is formed by using "was" or "were" with the verb in the "-ing" form. In this sentence, "are playing" becomes "were playing."
By following these rules for each tense, you can effectively rewrite the given sentences to match the specified verb tense accurately.
