Listen to the birds sing.

I put ' escuchar al canto de los pájaros'. I don't understand why this is incorrect as another option given was 'escuchar a los pájaros cantar'

I'm not sure when I can use escuchar + a

Gracias

I know that this construction (using cómo si + indicative to express indifference) is common in colloquial speech.  My question:  Is this a currently officially excepted grammatical construction by the RAE?  I found one source that says that the RAE says that this construction is common but must be considered incorrect.  But I am not sure if I’m looking at the most appropriate or most updated source.

Lesson = Me gusta viajar en tren.  Why not gusto?  I like = gusto, right?  Also, pretty much the same question for the use of cuesta, not cuesto in this lesson. Aren't they referring to the (masculine) ticket (el billete)?  I have a feeling I am missing something covered in our lessons!  

(As always, thank you for your help)

Hola!

is it true that "vago" or "perezoso" can be used with both "ser" and "estar", depending on whether it's a permanent personality trait or just a current mood? 

Gracias!

What would be the best way to clarify between, for example: 

"We will send the exam results out within the next two weeks." [at some point during that time frame]

and 

"We will send the exam results out in two weeks." [after two weeks have passed]

Is there a general rule about when the definite article must be used? Eg, in this exercise why does ‘fortuna’ not have one while abundancia, prosperidad and economía do?

Darn! once again is am trying to re-take a quiz I (really) need to work on. Message displayed after taking first quiz: "This lesson is already in your notebook. Go to your notebook now to kwiz this topic as many times as you like." Yesterday I reported this and shortly later I was able to retake the quiz (and still struggle). So, I studied and read ALOT today and want to take the quiz again. Is there a timer I need to know about (i.e. you must wait 12/24 hours before retaking a quiz? Sure would like to get a better understanding on this lesson and quiz's do show if I am "getting it" or not.  As always you help is VERY much appreciated.  :)

What did you mean when you wrote the tip "The full set of six forms is used with the past participles of another verb to form another tense, El Futuro Perfecto, for example..."?

I'm a little confused on what you mean by that, so if you can please explain it to me or give an example, I would greatly appreciate it. 

Kwizik didn´t accept my answer on the quiz for this area when I used 'recetado' instead of  'prescrito'. Is there a reason?
