Explanation:
1. Teresa and I study at the Autonomous University of Madrid.
The verb you should use here is estudiar which means to study. It belongs in the first group of regular Spanish verbs ending in -AR. It does not need a direct object neither in Spanish nor in English. In this sentence the subject is plural, Teresa y yo, and you should choose the form for nosotros.
2. Teresa studies foreign languages.
In the second sentence we have the same verb, estudiar, in the same verbal form of the presente del indicativo, only this time accompanied by a direct object: what does she study? lenguas extranjeras. The subject here is Teresa, and takes the form of the third person singular: ella.
3. She wants to work in the United Nations.
The verb we have in the third sentence is desear, which means to wish, to want. Just like estudiar, it is part of the group of verbs in -AR and conjugates regularly. When we talk about what we want to do, we use the structure desear + infinitive form, for example: deseo cantar.
4, I take journalism classes.
This sentence introduces the verb tomar which means to take as in to take classes, but we can also use it as the Spanish equivalent of the verb to drink: tomar un café. It demands a direct object (here clases de periodismo) and in this particual case we must use the first person singular form: yo tomo.
5. I like to sing and dance, too.
In this fifth sentence we have a special form that expresses likes/dislikes in Spanish. It is the verb gustar which only has the form of third person singular and plural. We use a pronoun in order to indicate who is it that likes this. It is conjugated as follows:
(a mí) ME gustA/gustAN... (a nosotros) NOS gustA/gustAN...
(a ti) TE gustA/gustAN... (a vosotros) OS gustA/gustAN...
(a él) LE gustA/gustAN... (a ellos) LES gustA/gustAN...
If we talk about what we like to do, we use the structure me/te/le/nos/os/les gusta + infinitive. and that is why we put me gusta CANTAR y BAILAR.
6. On Saturdays I sing with a tuna. It is a student music group.
In this sentence we used the verb cantar which means to sing. Here it is used without a direct object. It is a regular verb in the first person singular of the present tense and expresses a repeated action, such as a scheduled music group event.
7. The youth from the music group walk through the streets and sing Spanish traditional songs.
The new verb we have here is caminar meaning to walk. Just as the rest of the verbs it belongs to the regular -AR group. The subject of both of the verbs in this sentence is los jóvenes which is plural in Spanish and takes the form of the third person plural - ellos.
Here's how to conjugate the -AR group:
yo CANT-O nosotros CANT-AMOS
tú CANT-AS vosotros CANT-ÁIS
él CANT-A ellos CANT-AN
Happy learning!
