Repaso de los verbos (ar, er, ir) en el presente
Entramos en la nave. This is the first sentence you see. Why is "entramos" bold and blue? This is a good place in which to review the verbs. 
In Spanish 1 we concentrated solely on the present tense (what is taking place now). Remember that the verbs in Spanish have three endings: ar, er, and ir. In this section we will reflect on how to conjugate a regular verb in the present tense. 
In the three charts below, you will notice that the endings are crossed out. This is to remind you that the endings must first be dropped before the new endings can be added. The new endings are in red. 
You will also notice that in the left column under each heading are the singular forms of the verb. The plural forms can be found in the right column. Therefore, if a subject is singular, the verb must end in one of the endings in the left column. (Hint: If the subject is singular and does not say yo or tú, you will always use the él, ella, usted form of the verb. If the subject is plural and does not include you [does not say nosotros or __________ y yo] then the ellos, ellas, ustedes form is used [unless you are in Spain and wish to use the vosotros form])	

HABLAR- TO SPEAK		
yo hablo	nosotros, nosotras hablamos	
tú hablas	vosotros, vosotras habláis	
él, ella, usted habla	ellos, ellas, ustedes hablan	

COMER - TO EAT 		
yo como 	nosotros, nosotras comemos 	
tú comes	vosotros, vosotras coméis 	
él, ella, usted come	ellos, ellas, ustedes comen	

VIVIR - TO LIVE		
yo vivo	nosotros vivimos	
tú vives	vosotros, vosotras vivís 	
él, ella, usted vive	ellos, ellas, ustedes viven	

Notice how the endings of the er and ir verbs have a pattern. This pattern can be used for any regular er or ir verb. What else do you notice about the above endings? Do you see any similarities? Yes, you are right! The er and ir verbs have exactly the same endings, except for in the nosotros and vosotros forms. This should make it easier for you to remember. Now let's look at some other regular ar, er and ir verbs and their meanings. 	

ar verbs	er verbs	ir verbs	
entrar - to enter	aprender - to learn	abrir - to open	
buscar - to look for	beber - to drink	asistir - to attend	
trabajar - to work	comprender - to understand	escribir -to write	
mirar - to watch, to look at	correr - to run	recibir - to receive	
escuchar - to listen to 	leer - to read		
ayudar - to help	vender - to sell		

What form of hablar would we use when talking about Susita? 
You can't see Susita's name on the chart, but what pronoun there would take the place of Susita? 
Sí, ella. So we could say Susita habla or ella habla. 
And what about Paco? 
Paco habla or él habla is the correct answer! 
What about Susita and Paco? 
That's it! Paco y Susita hablan or ellos hablan.
If you are talking about yourself and someone else you would say Pablo y yo. You would then use the nosotros form because nosotros is another word for "we."
Pablo y yo hablamos or nosotros hablamos.
Another verb that you see mentioned here is the verb hay. Remember that hay means, "there is" or "there are." You would not use any of the above subject pronouns with this verb. Here are some examples: 
Hay veinte mesas en el comedor. There are twenty tables in the dining room.
Hay comida en el buffet. There is food at the buffet.
