FORMA AFIRMATIVA: SUJEITO + PRESENTE SIMPLES DO VERBO TO BE + GERÚNDIO (-ING) DO VERBO PRINCIPAL 2. Forma Negativa:A Forma Negativa do Presente Contínuo forma-se acrescentando not após o presente simples do verbo to be. Veja os exemplos abaixo:I'm not asking help. (Não estou pedindo ajuda.)He is not talking to you. (= He isn't talking to you.)
(Ele não está falando com você.)You are not working. (= You aren't working.)
(Você não está trabalhando.)FORMA NEGATIVA: SUJEITO + PRESENTE SIMPLES DO VERBO TO BE + NOT + GERÚNDIO DO VERBO PRINCIPAL 3. Forma Interrogativa:Na Forma Interrogativa do Presente Contínuo o sujeito se posiciona entre o presente simples do verbo to be e o gerúndio do verbo principal. Observe os exemplos abaixo:Am I being inopportune? (Estou sendo inoportuno?)Is she having dinner? (Ela está jantando?)What is he doing? (O que ele está fazendo?)What are they watching? (O que eles estão assistindo?)Where are you going (to)? (Para onde você vai?)Why is she crying?
(Por que ela está chorando?) FORMA INTERROGATIVA: PRESENTE SIMPLES DO VERBO TO BE + SUJEITO + GERÚNDIO DO VERBO PRINCIPAL (-ING) OBSERVAÇÃO: Devido às ideias que expressam, alguns verbos NÃO são usados no Tempo Contínuo: like, deslike, know, believe, understand, mean, remember, forget, prefer, hate, love, want, need, belong, smell, hear, see (com sentido de entender), imagine, recognise, realise, suppose, wish, agree, appear, astonish, deny, disagree, impress, promise, satisfy, seem, consist, contain, depend, deserve, lack, matter, measure, owe, own, possess, weigh.
