Question

открой скобк
Anna (to have a shower this mornin
We (to sing) a song on the party last night​

Answer 1

* Ann HAS HAD a shower this morning.

Связано с настоящим, этим утром, значит, нужен Present Perfect

* We SANG a song at the party last night.

Вчера вечером, не связано с настоящим, значит, Past Simple
