Answer 2

Olá, tudo bem?

A forma negativa, em Inglês, é realizada da seguinte forma:

Simple present (presente simples):
verbo auxiliar "do" + "not" + verbo infinitivo

*Atenção ao caso especial: quando o sujeito for 3ª pessoa do singular (He/She/It), faz-se da seguinte forma:
verbo auxiliar "does" + "not" + verbo infinitivo

Past Simple (Passado simples):
verbo auxiliar "did" + "not" + verbo infinitivo

Vamos aos exemplos:

a. The plants do not grow fast.
O sujeito ("The plants") está no plural e o verbo no presente, então deve ser combinado com "do".

b. The plants did not grow fast.
Verbo original no passado, então usa-se o auxiliar did + verbo no infinitivo.

c. The bus does not leave at 6.
"The bus" é 3ª pessoa do singular, que pede o uso de "does". O verbo vem no infinitivo.

d. The bus did not leave at 6.
  Frase original com verbo no passado. Então, a negativa é feita com o verbo auxiliar de passado simples "did" + not + verbo infinitivo.

e. He does not keep his money in a bank.
Mesmo caso da letra c.

f. He did not keep his money in a bank.
Mesmo caso da letra d.

g.John does not shut the shop at noon.
Mesmo caso da letra c.

h. John did not shut the shop at noon.
Mesmo caso da letra d.
