有現在完成式問題想問問

accompany verb, accompanied, accompanied

The shopping of the watch was accompanied by my friend this morning.

(something to happen or appear with somebody else.etc.)

had or have 都係相對比較性, 今次既時距係早上同下午, 你中間一段時間唔會咩都唔做, 所以會用 had.

* 但更常用係用過去式, "I bought this watch this morning", 因為你無任何事去做比較.

Ok in grammar.

Present perfect tense is often used to use an action or something has been done without indication of time.
