I need to create a sentence to tell the following people's opinions.

Tu / que / es aburrido(a)
Yo / Que / es emocionante
Nosotros/ que / es important para la ciudad.
Los maetros/ que / es interesante

Mi amigo(a) / que / es divertido(a)

Surely there is a model in your text book to follow? There are just so many things that could be done with the words you have. Is this "clause relater que" or "interrogative que" and they must be complex sentences?

This makes me "guess" at what you need and that makes me VERY uncomfortable.

Tú crees que es aburrido.
Yo pienso que es importante.
Yo digo que es emocionante.
Nosotros opinamos que es importante para la ciudad.

Mi amiga piensa que ella es divertida.

You can pick and choose what you like.

Sra

To create a sentence to express these people's opinions, we can follow this structure:

Subject + verb + adjective + complement.

1. Tu opinión: (Tu) crees que es aburrido(a).
To know how to say "you believe" in Spanish, we can use the verb "creer." For the subject, we use "tu," and the adjective "aburrido(a)" means boring.

2. Mi opinión: Yo creo que es emocionante.
To express "I believe," we can use the subject "yo" (I) and the verb "creer." The adjective "emocionante" means exciting.

3. Nuestra opinión: Nosotros creemos que es importante para la ciudad.
To express "we believe," we use the subject "nosotros" (we) and the verb "creer." The adjective "importante" means important, and we add "para la ciudad" (for the city) as a complement.

4. La opinión de los maestros: Los maestros creen que es interesante.
To express "the teachers believe," we use the subject "los maestros" (the teachers) and the verb "creer." The adjective "interesante" means interesting.

5. La opinión de mi amigo(a): Mi amigo(a) cree que es divertido(a).
To express "my friend believes," we use the phrase "mi amigo(a)" (my friend) as the subject, and the verb "creer." The adjective "divertido(a)" means fun.
