I was given this assignment: "Escribe en español un párrafo breve de por lo menos cuatro oraciones. Habla de la foto aquí usando los adjetivos demostrativos como pronombres." (The picture is of a woman on a computer with a man standing over her).

Are these sentences correct?

Ésta es una oficina.
Ése hombre está ayudando a la mujer.
Ésa mujer está usando la computadora.
Ésta computadora es encima de la mesa.

Thanks!

I'll send this to SraJMcGin.

First of all learn that the adjectives have no accent mark, and the next word is a noun. the pronouns all have accent marks because they stand alone with no noun.

The first is correct.
The 2nd must be without the noun = Ése está....

The 3rd has the same error as the 2nd. = Ésa está usando...

The 4th has the same error = Ésta es encima...

I'll flag this and come back later in case you have additional questions.

Sra

Ése es un hombre que está ayudando a una mujer. 

Ésa es una mujer que está usando la computadora. 

Ésta es una computadora que es encima de la mesa. 

are they correct now?
Thank you!!!

Yes, they are!

Sra

Yes, your sentences are correct! You have used the demonstrative adjectives as pronouns appropriately to refer to the objects in the picture.

To explain how you arrived at these sentences:

1. "Ésta es una oficina." To determine which demonstrative adjective to use, you need to identify the object or person close to you. In this case, we can see that the picture is showing a woman on a computer. Since the woman is closer to us, we use the feminine singular form of "this" which is "ésta". The sentence is correct because you correctly use the feminine singular form of "ésta" to refer to the office.

2. "Ése hombre está ayudando a la mujer." Again, we need to select the demonstrative adjective based on the relative position of the man and the woman in the picture. The man is slightly further from us, so we use the masculine singular form of "that" which is "ése". The sentence is correct because you use the masculine singular form of "ése" to refer to the man.

3. "Ésa mujer está usando la computadora." Similarly, we use the feminine singular form of "that" to refer specifically to the woman in the picture. The sentence is correct because you correctly use the feminine singular form of "ésa" to refer to the woman.

4. "Ésta computadora es encima de la mesa." In this sentence, you use the feminine singular form of "this" to refer to the computer, which is closer to us. The sentence is correct because you use the correct form of "ésta" to refer to the computer being on the table.

Overall, your sentences demonstrate a good understanding of how to use demonstrative adjectives as pronouns to describe objects and people in the picture. Keep up the good work!
