1. Cómo se evalúa esta unidad
Esta evaluación no pide cuatro temas separados: pide saber cuál estás usando. Before you answer, decide which time the item tests: an open future, an unlikely present or a closed past. Veintisiete reactivos en cuatro bloques y un solo caso: the robot stopped forty-five seconds into a ninety-second run and the team lost the fair by forty points. El bloque uno mide el presente improbable, el dos los conectores de condición, el tres el pasado cerrado y sus grados, y el cuatro la producción de un texto retrospectivo con su parte oral. Todos los datos que necesitas están en la tabla del caso; ningún reactivo exige inventar un hecho. The hypotheses become credible with numbers: two practices, a fifty-second short run and a forty-point margin.
| Bloque | Contenido | Reactivos | Puntos | Molde que mide |
|---|---|---|---|---|
| 1 | The unlikely present | 1 a 7 | 7 | Second and mixed conditional |
| 2 | Unless, in case, comma | 8 a 14 | 7 | Condition connectors |
| 3 | Rewriting the closed past | 15 a 21 | 7 | Third conditional and modals |
| 4 | Retrospective text and speaking | 22 a 27 | 6 | Integration |
| Total | Four mixed blocks | 27 | 27 | Four systems in one text |
A regret is honest when it names a real fact, an alternative you could control, and the consequence you accepted.
— Criterio con el que se calificó el bloque 4
2. El caso: the fair, the battery and four decisions
Todo el caso cerró el domingo 20 de septiembre. The team practised twice, charged the battery to eighty percent and never cleaned the sensor. Sobre esas cuatro decisiones el equipo puede imaginar lo contrario, y eso es justo lo que mide el instrumento.
| Elemento | Dato | Fuente | Estado |
|---|---|---|---|
| Fair date | 20 September 2026 | Official schedule | Closed |
| Run length | 90 seconds | Rulebook | Closed |
| Robot stopped at | 45 seconds | Judge sheet | Closed |
| Margin of loss | 40 points | Scoreboard | Closed |
| Practices that month | Twice | Team log | Confirmed |
| Practices the rules suggest | Five | Coach notes | Reference |
| Battery at the run | 80 percent | Charging log | Confirmed |
| Sensor cleaning | Once, in August | Maintenance card | Confirmed |
| Spare motor | The school has none | Inventory | Confirmed |
| Team feeling today | Disappointed | Interview | Open now |
Tres notas de lectura. Primera: el resultado de la feria es pasado cerrado, pero el enojo del equipo sigue vivo, así que un mismo hecho admite un third y un mixed. A mixed conditional joins a finished past cause with a present result, as in if we had practised we would not be disappointed now. Segunda: the story can be told in the passive to hide who acted, as in the sensor was cleaned once and the backup was never charged, y los renglones de mantenimiento están escritos así. Tercera: a second conditional claim usually sits below about twenty percent belief, and that is what makes it a dream instead of a plan; por eso "if we had a spare motor" es un sueño, no un plan.
3. Bloque 1: el presente improbable, reactivos 1 a 7
Bloque de second conditional y su puente al mixto. Cada hipótesis debe respetar el grado: si aún crees que puede pasar, no es second. When the speaker still believes something can happen the future stays open with a first conditional, not a dream.
Reactivo 1. The school owns no spare motor and the next fair is far. Choose the honest second conditional:
Reactivo 2. Why "If I were the coach" and not "If I was the coach" here?
Reactivo 3. Complete the advice: If I were you, I ___ the battery before the next run.
Reactivo 4. "If the robot was ready yesterday, it would pass" is the only possible form; were is mandatory in every register.
Reactivo 5. A second conditional usually sits below about twenty percent belief.
Reactivo 6. Complete: If we (have) one more week, we (rebuild) the arm.
Reactivo 7. The loss is Sunday (closed) but the team is disappointed now. Choose the mixed form:
4. Bloque 2: unless, in case y la coma, reactivos 8 a 14
Bloque de conectores. Recuerda que unless ya niega y que el verbo tras unless e in case va en presente. Unless means if not and already carries the negative, so the verb after it stays affirmative and in the present form. In case marks a precaution already taken against a possible event, and its verb stays in the present form.
Reactivo 8. "___ the battery holds a full charge, the robot stops mid-run."
Reactivo 9. Choose the precaution the team really took:
Reactivo 10. Why is "Unless the battery will hold a charge" wrong?
Reactivo 11. "Unless we do not hurry, we will miss the ride" is correct English.
Reactivo 12. Rewrite with one word: "If the code is not clean, the judges stop the run" becomes " the code is clean, the judges stop the run."
Reactivo 13. Which sentence places the comma correctly?
Reactivo 14. Sort each sentence by the connector it needs
Arrastra cada ficha a su categoría (o tócala y luego toca la categoría). También puedes usar el teclado.
5. Bloque 3: reescribir el pasado cerrado, reactivos 15 a 21
Bloque de third conditional y sus modales del pasado. La feria ya terminó, así que sólo la imaginación queda abierta. The third conditional rewrites a closed past, so if they had tested the sensor it would not have stopped on stage. Every have inside a conditional or a modal takes a past participle, and the irregular forms decide the accuracy.
Reactivo 15. The run failed on Sunday. Choose the correct regret:
Reactivo 16. A better calibration might have saved the run, so winning was possible but not certain. Choose it:
Reactivo 17. "I should have told the coach" needs an if clause to be correct.
Reactivo 18. Complete: If the sensor had been cleaned, the robot the run.
Reactivo 19. In "If we had slept well, we would think clearly now", the result refers to:
Reactivo 20. Match each sentence to its structure
Reactivo 21. Write the two hads: "If we more time, we would have fixed the arm."
6. Bloque 4: texto retrospectivo y decisión, reactivos 22 a 27
El bloque cuatro se contesta sobre tu propio texto retrospectivo de cien a ciento treinta palabras. The integrative text must use at least one second, one unless or in case, one third and one mixed conditional. Los seis reactivos revisan decisiones, no memoria. In a real retrospective paragraph the writer stacks third conditionals and then lands on one lesson in the present.
Reactivo 22. Your paragraph says "If the team would have practised, they would win". What is wrong?
Reactivo 23. Which line is a correct third conditional about the fair?
Reactivo 24. A classmate writes "Unless we will not practise, we lose". The best feedback is:
Reactivo 25. Which is the right order of a retrospective paragraph?
Reactivo 26. The written product must include one mixed conditional and at least one unless or in case.
Reactivo 27. In your peer checklist, what must every regret be anchored to?
7. Práctica guiada: el texto retrospectivo resuelto y justificado
Se resuelve el texto del caso con sus cuatro moldes y sus formas. The hypotheses become credible with numbers: two practices, a fifty-second short run and a forty-point margin. Este es el modelo contra el que te autoevalúas.
| Sección | Texto retrospectivo | Forma |
|---|---|---|
| 1. Fact | On 20 September our robot stopped at forty-five seconds and we lost by forty points. | Past simple, closed time |
| 1. Fact | The sensor was cleaned once and the spare battery was never charged. | Past passive |
| 2. Unlikely present | If the school had a spare motor, we would not be stuck for the next fair. | Second conditional |
| 2. Unlikely present | If I were the captain, I would change the maintenance card. | Advice with were |
| 3. Warning | Unless we clean the sensor, the same thing will happen. | Unless with present |
| 3. Warning | I will set an alarm in case I forget the charging again. | In case with present |
| 4. Closed past | If we had practised five times, we would have qualified. | Third conditional |
| 4. Closed past | If the battery had been full, we could have finished the run. | Could have |
| 4. Closed past | I should have checked the log on Friday. | Should have |
| 5. Mixed and lesson | If we had trained harder, we would not be this disappointed now. | Past cause, present result |
| 5. Mixed and lesson | But we did not, so the lesson is a schedule, not a wish. | Return to the fact |
Why does the last section switch to "would not be this disappointed now"?
Complete the warning line: we clean the sensor, the same thing happen, so I set an alarm I forget.
8. Simulación: el mismo hecho en tres sistemas
Simulación de un solo hecho del caso convertido en sus tres lecturas. Before you answer, decide which time the item tests: an open future, an unlikely present or a closed past. Tapa las tres últimas columnas, resuelve y compara.
| Hecho real | Second (ahora improbable) | Third (ayer cerrado) | Mixed (ayer con hoy) |
|---|---|---|---|
| We practised only twice | If we had more time, we would practise | If we had practised five times, we would have qualified | If we had practised, we would feel ready now |
| The battery was at 80% | If we had a full pack, we would run again | If we had charged it to 100%, it would not have stopped | If we had charged it, we would not be angry now |
| The sensor was dirty | If the sensor were clean, it would work | If we had cleaned the sensor, it would not have failed | If we had cleaned it, we would trust it now |
| The school has no motor | If we had a motor, we would fix it | If we had had a motor, we would have swapped it | If we had had one, we would be ready |
| Nobody checked the log | If I were the coach, I would check it | If we had checked the log, we would have seen it | If we had checked it, we would not be surprised |
La quinta fila encierra la forma más difícil de la unidad: "If we had had a motor, we would have swapped it", con dos had en la condición. The double had of the past perfect reduces in speech, so if I had had is heard as if I ada had. Y al lado derecho, el pasado que aún escuece: had been full explica el enojo de hoy. A mixed conditional joins a finished past cause with a present result, as in if we had practised we would not be disappointed now.
Which cell correctly rewrites "The battery was at 80%" as a closed past?
Why is "If the sensor were clean, it would work" a second conditional and not a third?
Convert to the mixed form: "We did not train, and we are tired now" → If we had trained, we not this tired now.
9. Actividad de coevaluación del texto retrospectivo
Se intercambia el texto y se aplica la lista de seis chequeos. To defend a decisión orally you give the real fact, the alternative you weighed and the consequence you accepted. Cada chequeo se señala en un renglón concreto del texto del compañero.
- Chequeo 1: ¿la primera oración es un hecho con fecha o número? Márcala.
- Chequeo 2: ¿hay un unless con verbo afirmativo en presente? Si duplica la negación, corrígelo.
- Chequeo 3: ¿algún if trae would dentro? Márcalo: es el error caro.
- Chequeo 4: ¿cada have del texto va seguido de participio? Revisa los irregulares.
- Chequeo 5: ¿hay un mixed con now en el resultado?
- Chequeo 6: ¿cierra con una lección que retome el hecho?
- Devuelve el texto con un acierto señalado y una corrección concreta.
10. Errores frecuentes en la evaluación
| Lo que sale mal | Forma correcta | Por qué pasa | Cómo autocorregirte |
|---|---|---|---|
| If we would have practised | If we had practised | Would dentro de la condición | Tras if, past perfect |
| If we had practised, we would won | we would have won | Falta have o el participio | Would have participio |
| Unless we do not practise | Unless we practise | Doble negación | Borra el not tras unless |
| In case we will need it | In case we need it | Futuro tras in case | Tras in case, presente |
| I would have went | I would have gone | Base en vez de participio | Tras have, participio |
| If I would be the captain | If I were the captain | Would en la hipótesis presente | Were sin would |
| If we had had, we would have | If we had had time, we would have fixed it | Corta la frase sin objeto | Cada had pide su complemento |
| She said she would has finished | She said she would have finished | Has por have | Tras would, have siempre |
| If the battery were full, it will not stop | If the battery were full, it would not stop | Mezcla will con were | Were pide would |
| We should have practised five time | We should have practised five times | Plural perdido | Revisa número y participio |
Los dos primeros aparecen en más de la mitad de los exámenes. The recurring exam errors are would inside the if, a base form after have, and a double negative after unless. Revisa nada más esas dos formas antes de entregar: cero would dentro del if y un participio detrás de cada have.

15. Resumen de la unidad
the second conditional imagines an unlikely or impossible present, so if the team had a spare motor they would not be stuck now. Advice and impossible wishes keep were in every person, so If I were the coach and If she were ready are both correct. A second conditional claim usually sits below about twenty percent belief, and that is what makes it a dream instead of a plan. A mixed conditional joins a finished past cause with a present result, as in if we had practised we would not be disappointed now. unless means if not and already carries the negative, so the verb after it stays affirmative and in the present form. In case marks a precaution already taken against a possible event, and its verb stays in the present form. A conditional clause that opens the sentence takes a comma, and that comma disappears when the clause moves to second place. The third conditional rewrites a closed past, so if they had tested the sensor it would not have stopped on stage. Could have and might have soften a regret into a lost possibility instead of a certain result. Should have plus participle criticises a past choice without needing any if clause. every have inside a conditional or a modal takes a past participle, and the irregular forms decide the accuracy. The double had of the past perfect reduces in speech, so if I had had is heard as if I ada had. The story can be told in the passive to hide who acted, as in the sensor was cleaned once and the backup was never charged. A good retrospective text opens with the fact, imagines the alternative and returns to the fact before it closes. In a real retrospective paragraph the writer stacks third conditionals and then lands on one lesson in the present. Before you answer, decide which time the item tests: an open future, an unlikely present or a closed past.

18. Fuentes y continuidad
Instrumento construido sobre el programa analítico de Lengua Adicional. Inglés III (SEP/DGB, semestre 3) con referencia al MCCEMS y al nivel A2+ a B1 del Marco Común Europeo. El caso del robot, los hechos con fechas y los borradores fueron escritos para este objeto y no provienen de materiales con derechos de autor; la retroalimentación de la hoja de respuestas explica el criterio, no sólo la forma correcta. El programa de semestre 3 pide integrar condicionales, conectores de condición y modales del pasado en una producción oral y escrita sobre un caso real.
Autoevaluación de este objeto
Aquí se mira lo que ya fuiste acertando. Pulsa «Comprobar» para saber si puedes seguir.
El robot detenido: imaginar, advertir, arrepentirse
- Un hecho, tres gramáticas del "qué si"
The robot stopped forty-five seconds into a ninety-second run and the team lost by forty points. Sobre ese hecho cerrado puedes soñar el presente (second), reescribir el pasado (third) y mezclar causa pasada con resultado de hoy (mixed). ¿Qué hecho del caso está cerrado?
- Second: el presente improbable
El second imagina un hoy falso: if the team had a spare motor they would not be stuck now. Vive bajo el veinte por ciento de creencia, por eso es un sueño y no un plan. Were se conserva en toda persona: if I were the coach. ¿Por qué "were" y no "was" aquí?
- Unless e in case: verbos en presente
Unless ya niega (if not), así que el verbo tras él va afirmativo y en presente: unless we clean the sensor. In case marca una precaución ya tomada: I set an alarm in case I forget. Prohibido el will después de estos conectores. ¿"Unless we will not practise" es correcto?
- Third: arrepentir el pasado cerrado
The third rewrites a closed past: if they had tested the sensor it would not have stopped on stage. Cuidado con el had had doble: if we had had more time suena "ada had". Could have y might have suavizan el arrepentimiento a posibilidad perdida. ¿Qué error caro mete "would" dentro del if?
- Mixed y el texto retrospectivo
Un mixed une causa pasada con resultado de hoy: if we had practised we would not be disappointed now, con now en el resultado. Tu texto de 100 a 130 palabras debe traer un second, un unless o in case, dos third y un mixed, arrancando con el hecho. ¿Qué debe cerrar el texto retrospectivo?
