Oi amigo, tudo certo?
Essa questão é meio pessoal, mas sempre tem umas alternativas absurdas, rs. Caso vc precise mudar o que escrevi, lembre-se que o "already" significa "já" e que o "never" significa "nunca". Então, se eu responder e vc quiser trocar, mude um pelo outro, tá?
Explicando o que vou fazer:
Nas perguntas, vou só completar o Have you ever com o que ele já me deu do exercício, mudando o verbo para o da terceira coluna (perfect)
Nas respostas, a estrutura é
sujeito da frase (I) + have + never/already + verbo no perfect + resto da frase
Nesse caso, eu escreverei
I have never ou I have already e dps colocarei o verbo da terceira coluna das tabelas seguido do fim da frase (que é o que eu fiz ou não fiz)
Vamos lá:

I have never riden a horse

I have never eaten frog's legs.
