Question

Como coloco essas frases na forma negative sentences
My sister has red hair.
My dog eats chocolate.
This bus stop shop at Shere.

Answer 1

Neste caso as frases estão no presente, assim para colocar a frase no negativo você precisa usar o auxiliar do presente DO*/DOES + NOT ou DON'T/DOESN'T, que é a forma contraída.

DON'T vc usa para as pessoas I, you, we, they

DOESN'T vc usa para as pessoas she, he, it, qdo vc usar para estas pessoas precisa tirar o S do verbo

My sister has red hair.  - My sister doesn't have red hair.  

My dog eats chocolate.  My dog doesn't eat chocolate.  

This bus stop shop at Shere. This bus doesn't stop shop at Shere.
