Explicação:
Nessa atividade utiliza-se o -ing.
Tanto na afirmativa, negativa, e interrogativa o verbo permanece com o -ing, mas antes do verbo coloca-se o am/is/are dependendo do sujeito.
Mas todos os verbos + -ing, possui suas regras. (procure no google as regrinhas, recomento o "toda materia" aí terá todas as regrinhas que vc terá que memorizar).
O am/is/are na interrogativa é passado para o inicio da frase (antes do sujeito) e na negativa pode ser acrescentado o "not" ( am not / is not / are not) ou vc pode reduzir, só que pode apenas reduzir o "is" e "are" ( isn't / aren't).
Espero ter lhe ajudado.
