Answer:
"ser" and "estar", these two verbs differ on the condition of permanency of that what is being explained in the sentence.
It is better to use "ser" when you are expressing something that will be permanent, or most likely will be permanent.
it is better to use "estar" to express something that is likely to end in a short or medium term.
sometimes the verbs are interchangeable, in such cases is not needed to explain the length of the state expressed by the sentence.
The third sentence in the questions uses the literal translation from the English present continuous time to the Spanish "présente continuo"
ALICIA<em> </em><em>¿Dónde estás? </em>
DANIEL <em>No estoy muy seguro, no encuentro el nombre de la calle. Pero estoy </em><em>(2)</em><u><em>viendo</em></u><em> un centro comercial a mi izquierda y más allá parece que están </em><em>(3)</em><u><em>construyendo</em></u><em> un estadio de fútbol. </em><em>(4)</em><u><em>Hablando</em></u><em> de fútbol, ¿dónde tengo mis boletos? ¡He perdido mis entradas! </em>
ALICIA <em>Madre mia, ¡sigues </em><em>(5)</em><u><em>siendo</em></u><em> un desastre! Algún día te va a pasar algo serio. </em>
DANIEL <em>¡Siempre andas </em><em>(6)</em><u><em>pensando</em></u><em> lo peor! </em>
ALICIA <em>¡Y tú siempre estás </em><em>(7)</em><u><em>olvidándote</em></u><em> de todo! </em>
DANIEL <em>¡Ya estamos </em><em>(8)</em><u><em>discutiendo</em></u><em> otra vez! </em>
<h3>Translation: </h3>
ALICE Where are you?
DANIEL I'm not really sure, I can't find the name of the street. But I'm looking a shopping mall to my left and beyond that it looks like a soccer stadium is being built. Speaking of soccer, where are my tickets? I have lost my tickets!
ALICE Oh my gosh, you're still a mess! Someday something serious is going to happen to you.
DANIEL You're always thinking the worst!
ALICIA And you are always forgetting everything!
DANIEL We are already arguing again!
<h2><em>Spymore</em></h2>
A mi me gusta mucho ir a la playa. Hay muchos peces, cangrejos, estrellas de mar y otros más. No hay montañas obviamente por que es la playa, pero quizás a lo lejos se ve alguna. Hay animales, muchos diría yo tanto aves como marinos. Casi no voy porque no me alcanza el tiempo pero cuando pueda de seguro iré.
El: if the next word ends in an o/or
La: a
Los: os/ors
Las: as
For example, number 5 would be "El radio pequeño esta en la cocina."
For the bottom:
If it's la/las it's feminine.
If it's el/los it's masculine.
Hope that helped. :)
