Complete the sentence with the correct form of the verb in brackets: "Our school team has ____ (win) three tournaments this season."

Erklärung

This season is still running, so the present perfect is the natural tense and the verb must appear after has as the participle won. Win keeps only that one past form, so the team won in March spells the verb exactly the same way without any auxiliary. Winned is not English, and the base form cannot complete a perfect construction on its own.
