Infinitive or Gerund — English Bac Agro

In the Bac Agro stream, where English is coefficient 2, the Language section rewards precise grammar with quick marks. After enjoy, avoid or suggest the verb takes the gerund; after want, decide or hope it takes the to-infinitive — and a few verbs such as stop or remember change meaning depending on the form.

Dans le programme du Bac Agro

English carries a coefficient of 2 in the Bac Sciences Agronomiques stream, level with Philosophy. The stream is built on Mathematics (coefficient 7), then Physics-Chemistry, Life & Earth Sciences and Plant & Animal Sciences (coefficient 5 each). English plays the role of a mark-mover in the average rather than a make-or-break subject, but its themes on the environment and development connect naturally to the stream's science content.

À l'épreuve

Three parts: Reading Comprehension, Language, and Writing (about 180 words). The habit of thinking in systems — soil, plant, animal, climate — helps Agro candidates handle essay prompts on sustainable development and the environment, where a concrete, well-chosen example beats a list of vague ones.

Objectifs d'apprentissage

  • Apply this grammar point accurately in the Language section and in the guided writing of the Bac Agro English exam (coefficient 2)
  • Recognise verbs always followed by the gerund (enjoy, avoid, finish, mind, suggest, consider, risk, admit, deny)
  • Recognise verbs always followed by the to-infinitive (want, decide, hope, plan, promise, agree, refuse, manage, afford)
  • Distinguish the meaning of stop to do / stop doing and remember to do / remember doing
  • Apply the rule: every preposition is followed by the gerund, never the infinitive

Notions clés

Verbs followed by the gerund (-ing)

enjoy, avoid, finish, mind, suggest, consider, risk, admit, deny, keep (on), imagine + verb-ing. E.g. “I enjoy swimming.”, “She suggested going to the cinema.”

Verbs followed by the to-infinitive

want, decide, hope, plan, promise, agree, refuse, manage, afford, seem + to + base form. E.g. “He decided to leave.”, “They agreed to help.”

Dual-construction verbs, different meaning

stop to do (stop in order to do something) vs stop doing (give up a habit); remember to do (not forget to do it, before the action) vs remember doing (recall having done it, after the action); try to do (make an effort to succeed) vs try doing (experiment with a solution).

Erreurs fréquentes

1

Putting to after enjoy / avoid / finish / suggest: “I enjoy to swim” is wrong — use “I enjoy swimming”.

2

Confusing stop to do and stop doing: “He stopped to smoke” means he stopped (walking, for example) in order to smoke, not that he gave up smoking (stop smoking).

3

Forgetting that prepositions are always followed by the gerund: “interested in to learn” is wrong — use “interested in learning”.

Exemple corrigé

Énoncé

Correct and justify: “She suggested to go to the cinema. He stopped smoke last year.”

Correction

suggested to go. Suggest is followed by the gerund, never by to + infinitive: “She suggested going to the cinema.”
stopped smoke. The intended meaning is “he gave up smoking” (a habit): use the gerund, “He stopped smoking last year.” (stop to smoke would mean he paused what he was doing in order to smoke a cigarette).
Corrected sentence. “She suggested going to the cinema. He stopped smoking last year.”

3 exercices pour t'entraîner

Exercice 1

Easy
Choose the right form: “I look forward to (see / seeing) you soon.”
Voir la correction
seeing — in look forward to, “to” is a preposition here (not the infinitive marker), so it is followed by the gerund: “I look forward to seeing you soon.”

Exercice 2

Medium
Complete with the correct form of close: “I clearly remember ___ (close) the window before leaving.” (the memory is of an action already done)
Voir la correction
closing — remember + gerund describes recalling an action already done: “I clearly remember closing the window before leaving.” (remember + to + infinitive would mean “not to forget to close”, a future action).

Exercice 3

Hard
Correct: “He denied to steal the money, but he admitted to lie about it later.”
Voir la correction
Deny and admit are followed by the gerund, never by to + infinitive: “He denied stealing the money, but he admitted lying about it later.”

Questions fréquentes

How do I know whether a verb takes the gerund or the infinitive?

There is no general rule: it is a list to learn verb by verb (enjoy / avoid / finish / suggest → gerund; want / decide / hope / promise → infinitive). Learning the lists in meaning groups makes them easier to remember.

What comes after a preposition (in, at, about, for)?

Always the gerund, never the infinitive: “She is interested in learning French.”, “He apologised for being late.” This rule has no exceptions.

stop to do and stop doing — how do I tell them apart in the exam?

stop doing = give up an action or habit (the more frequent meaning). stop to do = pause (from doing something) in order to do something else: “He stopped to answer the phone” means he stopped (walking, working…) in order to answer.

English is only coefficient 2 in my stream — is it worth revision time?

Yes. A mark in English weighs in the average exactly like a mark in a science subject at coefficient 2, and it is usually easier to raise because it rests on method, not on accumulated knowledge. One organised weekly session — chapter, rule or words, example, short paragraph — is enough.

Is this grammar point actually tested on the Bac Agro English paper?

Yes — in the Language section as gap-fill, sentence-joining or error-correction, and indirectly in Writing, where the same structures decide whether a sentence is marked as accurate. One rule, two examples and one typical mistake per point is enough to cover both.
