GRAMMAR POINTS TO REMEMBER
When delivering an academic or business presentation about a historical event, you are essentially establishing a timeline of cause and effect.
- Establishing the Market Context (Past Continuous): Use was/were + V-ing to describe what the market, the consumers, or the company was experiencing before the disruption happened. It paints the background picture. (e.g., Consumers were looking for better technology.)
- Reporting the Key Events (Past Simple): Use V2/ed to state the undeniable facts, the sudden changes, and the final outcomes. This moves your presentation forward. (e.g., The competitor entered the market. The company went bankrupt.)
- Analyzing the Root Causes (Past Perfect): Use had + V3/ed to sound like a true analyst! This tense allows you to point backwards in time to explain the fatal mistakes that were made long before the actual collapse. (e.g., They failed because they had ignored the warnings.)
