SUBJUNCTIVE
Adverbial Clauses

Señorita Harrison
ADVERBIAL CLAUSE
   What's a clause?
       A group of words, containing a verb, that expresses an idea.
   What's an adverb?
       It tells how, when or why something is being done (when
        describing a verb).
   An adverbial clause is a group of words used to tell
    how, when or why something is being done. The
    subjunctive is often found in adverbial clauses.
       These are always introduced by certain conjunctions - Up
        until now we have been using "QUE" as our only conjunction
ESCAPA A
 En caso de que   IN CASE
 Sin que          WITHOUT
 Con tal de que   PROVIDED THAT
 Antes de que     BEFORE
 Para que         SO THAT
 A menos que      UNLESS

   A fin de que   SO THAT
ESCAPA A
 Indicates contingency, or actions that are reliant
  upon the completion of other actions.
 There are two things to remember with this
  group: If there is a "QUE", you must use the
  subjunctive.
 If there is no "QUE", you must use the
  infinitive. (Without the "que" these are prepositions
  and we know that infinitives always follow
  prepositions.)
 ALWAYS USE THE SUBJUNCTIVE WITH
  ESCAPA A
EXAMPLES OF ESCAPA A
   Yo te digo para que puedas saber dónde
    estaremos.
       I'm telling you so that you will know where we will be.

   Me afeito antes de que salgas para las clases.
       I shave before you leave for school.

   No podemos sacar buenas notas sin que el
    maestro nos ayude.
       We can't get good grades unless the teacher helps us.
EXAMPLES OF ESCAPA A

   No puedes sacar buenas notas sin estudiar.
       You can't get good grades without studying.

   Necesito la cuchilla para cortar el pan.
       I need the knife to cut the bread.


   No QUE = INFINITIVE
THE CD

   Hasta que         UNTIL

   En cuanto         AS SOON AS

   Cuando            WHEN

   Despúes de que    AFTER
THE CD
   Use indicative if the action is completed or habitual

   Use subjunctive if action is pending or has not yet
    materialized.

   The use of future tense and commands indicate
    that subjunctive is needed
EXAMPLES OF THE CD
   Te llamaré en cuanto (tan pronto como) llegue al hotel
       I'll call you as soon as I arrive at the hotel.
           ( I haven't yet arrived.)

       Start the homework when you get home.

       I'll leave when she is coming home.
