Unit Review & Progress Test

Unit review — Natural Disasters & Geological Processes

Al finalizar esta unidad, deberías ser capaz de discutir con fluidez temas complejos relacionados con la geología y los desastres naturales, utilizando un léxico avanzado y preciso. Habrás desarrollado la capacidad de describir procesos naturales, evaluar riesgos y discutir consecuencias humanas utilizando estructuras gramaticales sofisticadas.

Asimismo, habrás perfeccionado el uso de la elipsis y la sustitución para evitar la redundancia, una habilidad crucial para alcanzar el nivel C1. Ahora deberías poder mantener la cohesión en discursos largos y escritos académicos, evitando repeticiones innecesarias sin perder la claridad.

Grammar consolidation

Complete the following tasks using ellipsis and substitution (so, do so, not, none, one, etc.).

Part A: Sentence Transformation Rewrite the sentences so they have the same meaning, using the word in brackets.

1. I thought the earthquake would be devastating, but it wasn't. (not) The earthquake was devastating, but _.
2. "Will the volcanic eruption affect the flight paths?" "I expect they will." (so) "Will the volcanic eruption affect the flight paths?" "I expect ______."
3. Many people lost their homes, but only a few were injured. (one) Many people lost their homes, but only a ______ were injured.

Part B: Error Correction Identify and correct the error in each sentence.

4. The seismic activity was intense, and the tectonic plates moved so too.
5. We expected the tsunami to be much larger, but it was not so. (Wait, is this correct? If not, rewrite it to show the opposite intention).
6. Some scientists believe the fault line is active, and others believe it so.

Part C: Controlled Rewriting Rewrite the sentences to make them more natural/concise using substitution.

7. "Do you think the drought will continue?" "I hope it does not." (Rewrite using 'not')
8. We have several evacuation plans, but we need to choose the best plan. (Use 'one')
9. Some areas were hit by the hurricane, and other areas were also hit. (Use 'so')
10. "Did the landslide destroy the bridge?" "Yes, it did destroy the bridge." (Use 'do so')

3. The _ of the eruption left the landscape looking like another planet.
4. The movement of _ plates is responsible for most seismic activity.
5. The _ of the earthquake was located deep beneath the ocean floor.
6. The _ of the scale was so high that it was felt hundreds of miles away.

Task 2: Word Formation Complete the sentences by changing the form of the word in brackets.

7. The suddenness of the volcanic _ (ERUPT) caught the villagers by surprise.
8. The _ (DEVASTATE) caused by the flood was unprecedented.
9. Geologists study the _ (REFORM) of the earth's crust over millions of years.
10. The _ (STABILITY) of the hillside was compromised after the heavy rains.

Task 3: Register Choice Choose the most appropriate C1-level term to complete the sentence.

11. The government implemented _ (emergency/urgent/immediate) measures to evacuate the coastal regions.
12. The seismic waves caused _ (catastrophic/big/heavy) damage to the infrastructure.

Integrated skills task

Source Text: The Silent Threat

While sudden disasters like earthquakes capture global attention, slow-onset geological processes often pose a more insidious threat. Soil erosion and desertification, for instance, can destabilise entire ecosystems over decades. Unlike a sudden volcanic eruption, these processes are often ignored until the damage is irreversible. The gradual shifting of ground levels or the depletion of fertile land can lead to mass migration and resource wars, much like the suddenness of a storm. However, the lack of a single, dramatic event often results in a lack of political will to fund preventative measures. To mitigate these risks, we must move from a reactive stance to a proactive one, investing in sustainable land management and geological monitoring before the crisis reaches a breaking point.

Instrucciones para el estudiante: Escribe una respuesta (ensayo de opinión o carta formal) de entre 180 y 220 palabras. Debes evaluar si la falta de "impacto visual" de los desastres lentos es realmente el mayor obstáculo para la prevención. Utiliza el vocabulario de la unidad y las estructuras de elipsis/sustitución aprendidas.

Speaking checkpoint

1. Compare: Compare the immediate psychological impact of a sudden natural disaster with the long-term impact of a slow-onset environmental change.
2. Speculate: How might urban planning change in the next fifty years if sea levels continue to rise at the current rate?
3. Evaluate: "Governments should prioritise immediate disaster relief over long-term geological prevention." To what extent do you agree?
4. Justify: Why do you think some societies are more resilient to natural disasters than others? Provide reasons for your answer.
5. Compare: Compare the effectiveness of technological warnings (like tsunami sensors) versus community-based education in disaster management.
6. Speculate: If a massive volcanic eruption were to occur tomorrow, how would the global economy be affected?
