In English "nuestra" and "nuestro" is "our".

Tearing 你好! - "nuestra" = our ( female ) 我们的 " Ella es nuestra mamá / madre" = She is our mother = 她是我们妈妈 - "nuestro" = our ( male ) 我们的 " Él es nuestro papá / padre " = He is our father = 他是我们爸爸 There's no difference in the translation to English for the word OUR, but in Spanish it changes the genre. 不好意思，我的中文不太好。 Best wishes Sofía.
