A Great! I scored two goals. We 1 the match 6–0. The team we 2 weren’t very good, though. They’ve 3 every 4 they’ve played this year. Most of the 5 on their team couldn’t even 6 the ball properly!

A Great! I scored two goals. We 1 won the match 6–0. The team we 2 beat weren’t very good, though. They’ve 3 lost every 4 match they’ve played this year. Most of the 5 players on their team couldn’t even 6 kick the ball properly!

Explanation:

This question mixes the use of nouns and verbs to complete the gaps. It is important to pay attention to the verbs because they need to be changed to express the proper tense. Since the speaker is talking about something that took place at a specific time in the past, we must use verbs in their past form. So:

win - won

beat - beat

However, we do have a present perfect in the excerpt. In that case, we complete it with the past participle form:

lose - lost

We also have a modal verb (could) in the passage. The verb that follows a modal verb should be used in its base form without "to". In this case, it was "kick".
