Exercise 6
Task reminder: After the recording, you have 40 seconds to re-tell the lecture in your own words. Mention the topic, key points, and any examples. Speak continuously — pausing loses marks.
1. Re-tell Lecture: Sample 1 — Artificial Sweeteners and Health
A lecture reviewing current evidence on the health effects of artificial sweeteners such as aspartame, sucralose, and stevia. The speaker covers research suggesting that while these substances contain few calories, they may alter gut microbiome composition and insulin sensitivity in ways that could partially undermine their intended health benefits.
Sample Notes 2. Re-tell Lecture: Sample 2 — The Ethics of Autonomous Weapons An examination of the ethical, legal, and strategic implications of autonomous weapons systems that can select and engage targets without human intervention. The lecture covers arguments about accountability, compliance with international humanitarian law, and the risk of lowering the threshold for conflict. Sample Notes 3. Re-tell Lecture: Sample 3 — Antarctic Ice and Sea Level Rise A lecture on the dynamics of the Antarctic ice sheet and its potential contribution to global sea level rise. The speaker explains the difference between ice shelves and land ice, the processes by which warming destabilises ice sheets, and the wide range of sea level projections and their implications for coastal communities.
