Question

1°. Todas as sentenças abaixo estão no Passado Simples, coloque-as na
forma negativa:

a) I wrote letters to my friends.
b) Monique traveled alone.
c) Mary and Sally paid the bills yesterday.
d) We knew to do the tests.
e) Peter met my sister last week.
f)That girl broke her arm.
g)Sabrina told the truth about you.

Answer 1

a) I did not write letters to my friends.

b) Monique did not travel alone.

c) Mary and Sally did not pay the bills yesterday.

d) We did not know to do the tests.

e) Peter did not meet my sister last week.

f)That girl did not break her arm.

g)Sabrina did not tell the truth about you.

>> Para passar as frases para a forma negativa é preciso adicionar o auxiliar did + not após o sujeito da frase, e lembrando que o verbo que virá após did not não pode estar conjugado no passado, exemplo: she told me the truth < told é o passado de Tell então para passar a frase para a forma negativa terá que ser acrescentado o did not após o sujeito she e o verbo told ficará tell .

>> She did not tell the truth
