Advances in Science and Technology — English Bac Lettres

Dans le programme du Bac Lettres

English is a major subject in the Bac Lettres stream, with a coefficient of 4 — second only to Arabic Language (coefficient 7) and ahead of History-Geography and Philosophy (coefficient 3). There is no Mathematics in the stream. The high coefficient raises the bar: richer vocabulary, more developed argumentative writing, and firmer control of register and style are expected, and the English mark genuinely shapes the average.

À l'épreuve

Three parts: Reading Comprehension, Language, and Writing. In the Lettres stream the Writing task is longer and more demanding — a structured essay with a clear thesis, developed arguments on both sides, illustrative examples and a personal conclusion — and language accuracy and range are scored throughout.

Objectifs d'apprentissage

Reuse this vocabulary field in the Bac Lettres Reading answers and in the argumentative essay (coefficient 4)
Use the vocabulary of innovation: breakthrough, innovation, invention, discovery, cutting-edge technology
Name fields of technological advance: artificial intelligence, renewable energy, genetic engineering, space exploration
Weigh benefits and drawbacks: benefits / advantages vs risks / drawbacks / threats
Build a balanced essay on scientific progress (thesis, antithesis, personal position)

Notions clés

Vocabulary of innovation

breakthrough (a major advance), innovation, invention, discovery, cutting-edge technology. E.g. “The discovery of CRISPR was a major breakthrough in genetic engineering.”

Fields of scientific advance

artificial intelligence (AI), renewable energy, genetic engineering, space exploration — themes directly linked to the science content of many streams.

Weighing pros and cons

benefits / advantages (better health, efficiency, access to information) vs risks / drawbacks / threats (job losses, technological dependence, ethical questions). A successful essay presents both before concluding.

Erreurs fréquentes

Confusing invention (creating something new that did not exist) with discovery (revealing something that already existed but was unknown, such as a physical law or a species).

Writing a one-sided essay (only for or only against technological progress): the prompt almost always calls for a nuanced answer.

Using advance as an uncountable noun and over-generalising: speak of advances (plural) or an advance in a specific field to stay precise.

Exemple corrigé

Énoncé

Write a nuanced concluding sentence for an essay on: “Is artificial intelligence a threat or an opportunity for society?”

Correction

Recall both sides of the debate. Mention both the benefits (efficiency, medical advances) and the risks (job losses, ethical questions) already developed in the essay.

Take a nuanced personal position. Avoid an absolute verdict; prefer a conditional conclusion (“if properly regulated”).

Result. “Overall, artificial intelligence seems to offer more opportunities than threats, provided that governments and companies regulate its use responsibly to protect jobs and ethical standards.”

drawback — the other three name a positive advance, while drawback names a disadvantage.

Exercice 2

Medium

Complete: “The ___ of penicillin by Alexander Fleming saved millions of lives.” (invention / discovery)

Voir la correction

discovery — penicillin already existed in nature (a mould); Fleming discovered it, he did not invent it.

Exercice 3

Hard

Write a sentence contrasting a benefit and a risk of artificial intelligence with a contrast connector.

Voir la correction

“While artificial intelligence can significantly improve medical diagnosis, it also raises serious concerns about job losses in several industries.” — while joins a benefit (medical diagnosis) and a risk (job losses) in one balanced sentence.

Questions fréquentes

How does this chapter specifically help science-stream candidates?

They already study energy, genetics or electricity in their other subjects; this chapter lets them reuse that scientific background — in English — to enrich an essay with precise, credible examples, an edge other streams do not always have.

Do I always have to conclude that technology is positive?

No; what matters is the quality of the argument and the balance between the two viewpoints, not the conclusion itself — a nuanced, well-justified conclusion (“both… but…”) scores better than a blunt position with no nuance.

What concrete examples can I use to illustrate this theme?

Varied, current examples: mRNA vaccines, electric cars, solar and wind energy, generative artificial intelligence — choose one you know well rather than citing several superficially.

English is coefficient 4 in the Lettres stream — how do I revise it seriously?

Treat it as a core subject. For each of the 31 chapters, fix the rule or the word field with two solid examples, and write at least one full essay a fortnight under timed conditions. Read short English articles to build argumentative vocabulary and sentence variety, since range and accuracy are marked directly.

How do I use this theme in the Bac Lettres essay without sounding generic?

Anchor each key term in one concrete, personal example — a place, a person, a situation you know. A specific illustration in accurate English scores better than a long list of terms with no support, on any of the society prompts in the programme.
