► FORMA AFIRMATIVA.
1) há um livro aqui = there is a book here

2) há dez livros aqui = there are ten books.

Veja que no singular empreguei there is e no plural there are.

Se passemos as frases para o passado ficariam assim:

3) there was (singular)

4) there were (plural)

Se fosse no futuro

5) there Will be (singular)

6) there Will be (plural).

►FORMA NEGATIVA
1) há NÃO um livro aqui = there is NOT a book here

2) há NÃO dez livros aqui = there are NOT ten books.

Se passemos as frases para o passado ficariam assim:

3) there was NOT (singular)

4) there were NOT (plural)

Se fosse no futuro

5) there Will NOT be
