Reduced relative & participle clauses complejas
A nivel C1 es fundamental compactar información. En vez de usar siempre oraciones de relativo completas, el inglés escrito prefiere reduced relative clauses y participle clauses para sonar más denso y elegante.
1) Mapa rápido
Full: Students who live on campus often feel isolated.
Reduced: Students living on campus often feel isolated.
Full: Data that were collected in 2020 are limited.
Reduced: Data collected in 2020 are limited.
Misma información, menos palabras y estilo más compacto.
Piensa en estas estructuras como “atajos” para convertir dos ideas en un solo sintagma nominal complejo.
2) Recordatorio: oraciones de relativo completas
Antes de reducir, asegúrate de dominar la versión completa. Estructura base:
| Tipo | Ejemplo (completa) | Función |
|---|---|---|
| Defining (especificativa) | The boy who lives next door is very shy. The book that you recommended was excellent. | Identificar de qué persona/objeto hablamos. Sin la relativa, la frase cambia de sentido. |
| Non-defining (explicativa) | My brother, who lives in Canada, is visiting us. The report, which was published yesterday, caused controversy. | Añadir información extra, entre comas; se puede eliminar sin perder referencia. |
| Relativo + verbo finito | who lives, which was written, that has been approved… | Es lo que vamos a reducir usando -ing, -ed o having + participle. |
Solo puedes reducir cuando la oración de relativo comparte el mismo sujeto que el sustantivo al que modifica (no cuando hay cambio de sujeto).
3) Reduced relatives con -ing (función activa)
Usamos -ing cuando la oración de relativo expresa una acción activa realizada por el sustantivo (como sujeto).
| Completa | Reducida | Idea |
|---|---|---|
| People who are working remotely face new challenges. | People working remotely face new challenges. | Acción en curso / característica actual. |
| Students who study abroad gain valuable experience. | Students studying abroad gain valuable experience. | Hábito/característica del grupo (no solo una vez). |
| The company which operates in several countries is hiring. | The company operating in several countries is hiring. | Información descriptiva compactada en el sintagma nominal. |
| Anyone who wants to participate must register first. | Anyone wanting to participate must register first. | Enfoque en condición / requisito general. |
Full: The people who live in urban areas often experience higher stress levels.
Reduced: People living in urban areas often experience higher stress levels.
Muy frecuente en introducciones de ensayos: Students studying abroad…, Companies operating globally…, etc.
4) Reduced relatives con participio pasado (-ed) (voz pasiva / resultado)
Usamos el participio pasado cuando el sustantivo recibe la acción (equivalente a una relativa en voz pasiva).
| Completa | Reducida | Idea |
|---|---|---|
| The data that were collected in 2020 are limited. | The data collected in 2020 are limited. | Datos “recogidos” en 2020 → énfasis en origen. |
| The article which was published yesterday caused debate. | The article published yesterday caused debate. | Información temporal compacta (ayer). |
| The buildings that were destroyed in the fire have not been rebuilt. | The buildings destroyed in the fire have not been rebuilt. | Participio = adjetivo derivado de la acción pasada. |
| The measures that are proposed in the report are ambitious. | The measures proposed in the report are ambitious. | Muy típico en informes y documentos académicos. |
A menudo la cláusula reducida con participio se comporta como un adjetivo complejo: data collected recently, students admitted last year, etc.
5) Participle clauses: -ing, -ed, perfect
Además de modificar un sustantivo, las participle clauses pueden funcionar como una especie de oración subordinada comprimida, aportando ideas de tiempo, causa, condición o resultado.
| Tipo | Ejemplo | Relación implícita |
|---|---|---|
| -ing (simultaneidad / causa) | Feeling tired, she decided to leave early. (As she was feeling tired…) Not knowing what to say, he remained silent. (Because he didn’t know…) | Tiempo o causa; sujeto = mismo que en la oración principal. |
| -ed (condición / motivo) | Given the complexity of the issue, further research is needed. (Because the issue is complex…) Surrounded by strangers, he felt uncomfortable. | Voz pasiva implícita o estado resultado de una acción previa. |
| Perfect participle (having + V-ed) | Having finished the report, she sent it to her supervisor. (After she had finished…) Having been warned about the risks, they proceeded with caution. | Acción anterior a la principal (anterioridad + conexión causal). |
Having completed the initial tests, the team decided to expand the study.
(= After they had completed the initial tests…)
Muy importante: en estas cláusulas el sujeto implícito debe ser el mismo que en la oración principal para evitar errores de “misplaced modifier”.
6) Errores típicos con reduced relatives y participles
| Error | Problema | Versión correcta / comentario |
|---|---|---|
| *People living in the city they suffer from pollution.* | Doble sujeto; la cláusula reducida ya cumple función de relativo. | People living in the city suffer from pollution. |
| *The report written by students who are interesting was published.* | Orden confuso; parece que los estudiantes son “interesting”, no el informe. | The report written by students, which is very interesting, was published. o: The very interesting report written by students was published. |
| Misplaced participle | *Walking down the street, the wind was very cold.* (¿Quién caminaba?) | Walking down the street, I felt the wind was very cold. (El sujeto implícito = “I”.) |
| Reducir cuando los sujetos no coinciden | *Having finished the meal, the bill was paid.* (parece que la “meal” pagó la cuenta) | Having finished the meal, we paid the bill. o: After we had finished the meal, the bill was paid. |
| Exceso de cláusulas reducidas en un solo sintagma | Hace la frase muy difícil de leer. | Alternar entre cláusulas reducidas y estructuras más simples para mantener claridad. |
