Explanation:
Across:
4. La maestra dio dulces a los estudiantes.
The teacher gave sweets to the students.
In order to choose the correct short forms, we must first look for nouns:
the first noun is <em>maestra. </em>It is feminine and it acts as the subject so we choose the option <u>ella.</u>
<em>Dulces </em>isn the direct object of the verb <em>dar </em>and is masculine. It is in its plural form so it should be replaced with the pronoun <u>los.</u>
<em>A los estudiantes </em>acts as the indirect object. It is in plural so the corresponding form is <u>les.</u> BUT since <u>there are two third person pronouns in a sentence</u> (les / los), the indirect pronoun <em>must be transformed</em> in its alternative form <u>se</u>. Also it should always precede the direct object pronoun: ella se los dio.
Down:
1. Nosotros recogimos dinero para los pobres.
We are collecting money for the poor.
<em>Nosotros</em> is the subject but <u>it's already a pronoun</u> so it stays the same.
<em>Dinero </em>acts as the direct object of the sentence. It is a masculine noun in its singular form so the correct form is <u>lo.</u>
Since <em>para los pobres</em> should not be used, the corrected sentence is: nosotros lo recogimos (otherwise it would be <em>nosotros </em><em>SE lo </em><em>recogimos).</em>
2. Los estudiantes entregaron la tarea a la maestra.
The students submitted the homework to the teacher.
<em>Los estudiantes </em>is a masculine noun in its plural form. It acts as the subject of the sentence, so we use the subject pronoun <u>ellos.</u>
<em>La tarea </em>is a feminine noun in its singular form. It is the direct object of the verb <em>entregar</em> and we must use the direct object pronoun <u>la.</u>
<em>A la maestra </em>serves the indirect object of the sentence and therefore its corresponding pronoun would be <u>le</u> BUT here again we have two juxtaposed (placed side by side) third person object pronouns, and the <em>indirect one </em>becomes <u>se</u>: ellos SE la entregaron.
3. Laura compró unos perritos para sus hijos.
Laura bought some puppies for her kids.
<em>Laura </em>is a feminine noun (name) in its singular and acts as the subject so we replace it with <u>ella</u>.
<em>Unos perritos </em>is a masculine noun in its plural form. It is the direct object and the correct pronoun should be <u>los</u>.
<em>Para sus hijos </em>is a masculine noun in its plural form and since it acts as the indirect object of the sentence, its corresponding pronoun is <u>les</u> BUT since we have two object pronouns for the third person, it takes the form <u>se</u>: ella SE los compró.
4. Mi perro me dio muchos besitos.
My dog gave me many kisses.
<em>Mi perro </em>is a masculine noun in its singular form and is a subject of this sentence. Therefore we use the pronoun <u>él</u>.
<em>Me </em>refers to the first person's indirect object form. It stays as it is!
<em>Muchos besitos </em>is the direct object of the sentence. It is a masculine noun in its plural form and should be replaced with the pronoun <u>los</u>.
The indirect object pronoun ALWAYS goes first and here we have: él me los dio.
