GRAMÁTICA 6
Voz pasiva y voz activa

Al igual que en  español, en inglés existe voz activa y pasiva. La voz activa es la que usamos normalmente en la que hay un sujeto que realiza una acción. 
La voz pasiva se usa cuando queremos centrar la atención no en el sujeto, sino en el objeto o persona afectada por dicha acción.
Por eso, aunque el orden normal de las oraciones en inglés es:
  • The new shopping mall employs 125 people from Stratford
  • Sujeto + Verbo + Objeto 
Este orden cambia cuando usamos la pasiva para poner el énfasis en el objeto o persona afectada por la acción :  
  • 125 people from Stratford are employed by the new shopping mall
  •  Objeto + to be pasado participio  + Complementos
¡Importante! Solo los verbos transitivos pueden usarse en pasiva, ya que los intransitivos no tiene objeto.

¿Cómo se forma la voz pasiva?


La buena noticia es que la estructura de la pasiva es muy sencilla: lo importante es saber conjugar el verbo “to be.
La estructura básica es: sujeto + (to be) + participio pasado. 
Tiempo verbalEjemplo en pasiva
Present simpleThe film is directed by John Smith (La película está dirigida por John Smith).
Present continuousThe film is being directed by John Smith (La película está siendo dirigida por John Smith).
Past simpleThe film was directed by John Smith (La película fue dirigida por John Smith).
Past continuousThe film was being directed by John Smith (La película estaba siendo dirigida por John Smith).
Present perfectThe film has been directed by John Smith (La película ha sido dirigida por John Smith).
Past perfectThe film had been  directed by John Smith (La película había sido dirigida por John Smith).
Future (will)The film will be directed by John Smith (La película será dirigidapor John Smith).
Future (be going to)The film is going to be directed by John Smith (La película va a ser dirigida por John Smith).
Verbos modalesThe film should / might / must be  directed by John Smith (La película debería / podría / debe ser dirigida por John Smith).

¿Cuándo se usa esta estructura?
Podemos recurrir a la voz pasiva por varios motivos:

1. CUANDO ESTAMOS MÁS INTERESADOS EN LA PERSONA O COSA QUE RECIBE LA ACCIÓN QUE EN LA PERSONA O COSA QUE REALIZA LA ACCIÓN.

Observa estas dos frases. La frase A es pasiva, y la B es activa
A. Romeo & Juliet was written by William Shakespeare (Romeo y Julieta fue escrito por William Shakespeare).
B. Shakespeare wrote Romeo & Juliet (Shakespeare escribió Romeo y Julieta).
En la frase A, estamos más interesados en la obra de teatro, Romeo y Julieta, mientras que la frase B podría encontrarse en un texto sobre Shakespeare, en el que queremos centrarnos más en él que en la obra que escribió. 

2. CUANDO EL “AGENTE” ES OBVIO O NO TIENE IMPORTANCIA

El complemento agente en una oración pasiva es la persona o cosa que realiza o provoca la acción. A veces no es importante, o resulta tan evidente que no tenemos por qué mencionarlo.
He was arrested last night (Fue detenido anoche).
Aquí no necesitamos decir “The police arrested him” (“La policía lo detuvo”), pues es obvio que solo la policía tiene competencias para llevar a cabo una detención. 

3. CUANDO ESTAMOS DESCRIBIENDO PROCESOS Y QUEREMOS MANTENER EL CARÁCTER IMPERSONAL DE LA DESCRIPCIÓN.

Si estamos describiendo cómo se hace algo , por ejemplo, queremos centrarnos en las acciones, no en quién las lleva a cabo:
Chocolate eggs are made with milk and cocoa. The mixture is then poured into moulds
(Los huevos de chocolate se hacen con leche y cacao. Después se vierte la mezcla en moldes).

4. PARA EVITAR RESPONSABILIDADES

¿Recuerdas cuando la aerolínea canceló tu vuelo? Es muy poco probable que dijeran:
We have cancelled your flight (Hemos cancelado su vuelo)… aunque eso fuera lo que ocurrió.
Al utilizar la voz pasiva (Your flight has been cancelled), están evitando asumir la responsabilidad de la cancelación, con la esperanza de que dirijas tu frustración hacia otra parte. Esto sucede igualmente en los letreros que indican normas:
Smoking is not permitted (No se permite fumar)… que realmente significa “We do not permit smoking” (“No permitimos fumar”).

  15. How Twitter will revolutionise academic research and teaching


    Many members of academia marvel (or react with rejection) at the rapid changes in the production and dissemination of scholarly work and interaction between academics and those "outside" academic institutions. Thousands of scholars and higher education institutions are participating in social media (such as Twitter), as an important aspect of their research and teaching work.

    There is still considerable resistance to embracing social media tools for educational purposes, but if you are reading this article you are probably willing to consider their positive effects. New technologies have slow adoption cycles, and often the learning curve is steep. Those already using these tools within academic contexts should not be considered a priori as "the converted"; perception and usage of social media varies wildly, and due to the inherently fluid and malleable nature of the platforms themselves we are still in the process of assessing all their possibilities.

    Mobile phones and tablets enable the user in producing content, and to publish and disseminate it online. The microblogging platform Twitter is purposefully designed to exchange information and to facilitate reciprocal communication and attribution, therefore enabling the creation of communities of individuals interested in common topics. But the easy part of tweeting is publishing content; the difficult side is actually committing to active public engagement. This is where "the ear", our ability to listen and to place ourselves in a particular context at a particular time, comes to the fore.

    In traditional scholarly communications, academics produced a document (a thesis, an article, a book) and then sent it to someone else to review it, edit it, publish it, distribute it. It was a unidirectional mode of operation, even if the document was produced by research teams.

    Today, more and more academics are creating content and posting it online. They make it available, but this does not necessarily guarantee people will read it. Whereas online availability is very important, what brings the process to fruition is engagement: the work of scholarly authorship does not end with publication: that is just the beginning.

    Therefore, the 21st century scholar has the tools not only to publish and disseminate, but also to facilitate the development of specialised audiences, and therefore of what is called "impact": people read, and in turn write about your work, which is in turn read by others. "It's a conversation, not a lecture," is a well-known trope that is useful to remember in the scholarly web. This does not mean we should spend every waking hour chatting to strangers on social networks; it means that social media is not a uni-directional broadcasting tool. Those who "follow" us online are likely to be our students, colleagues, employers. They are not a passive audience.

    For higher education, social media is part of a process of democratisation. Its effective use can lead to an ethical shift towards active efforts for engaging new audiences and widening participation beyond the Ivory Tower's walls.
