Как составлять такие предложения:

Present Perfect образуется по формуле:

\[ \text{подлежащее} + \text{have/has} + \text{V3} \]

• have употребляется с I, we, they, you and I, these people;
• has — с my friend, everybody;
• после have/has ставится третья форма глагола: played, visited, cleaned.

Проверка:
Everybody означает «каждый», поэтому это единственное число: Everybody has, а не have.
