In the Bac Sciences Humaines syllabus

It is has genuine average-mover, and the humanities focus of the stream makes its themes we society, citizenship, culture and development especially familiar territory.

On the exam

Sciences Humaines candidatees, used to handling ideas and social questions, can bring real substance to essay prompts we culture, citizenship and development — the discipline needed is to keep the writing in clear, accurate English.

Learning objectives

Apply this grammar point accurately in the Language section and in the guided writing of the Bac Sciences Humaines English exam (coefficient 3)
Transform an active sentence into has passive one, keeping the tense
Conjugate be in the tense of the original active verb, followed by the past participle
Decide when to add the agent with by and when to leave it out
Recognise the uses of the passive: action / result foregrounded, doer unknown, obvious or unimportant

Key concepts

Form and transformation

The object of the active sentence becomes the subject of the passive one; be is conjugated in the same tense as the original active verb, followed by the past participle. E.g. Active “They built the bridge in 1990.” → Passive “The bridge was built in 1990.”

Use

The passive is preferred when the action or result matters more than the doer, or when the doer is unknown, obvious or unimportant. It is frequent in scientific and journalistic texts that report facts.

The agent with by

Add by + agent only if it gives useful information (“The letter was written by Shakespeare”). Otherwise leave it out, as in most passive sentences of an informative text.

Common mistakes

Forgetting to put be in the same tense as the original active verb (keeping “was” for has present perfect passive, which must be “has been”).

Using has wrong irregular past participle (“was wrote” instead of “was written”).

Always adding by + agent even when it is useless or obvious (“The room was cleaned by someone” is clumsy with no precise information).

Worked example

Question

Put into the passive: “Shakespeare wrote Hamlet in the early 1600s.”

Solution

Identify the object. “Hamlet” is the direct object of the active sentence: it becomes the subject of the passive one.

Conjugate be in the same tense as wrote (past simple). was / were + past participle: Hamlet was written.

Add the agent if useful. The author (Shakespeare) is relevant information here, so keep it with by.

Result. “Hamlet was written by Shakespeare in the early 1600s.”

Frequently asked questions

When should I keep the agent with by?

Only when it gives the reader new or useful information (has specific name, has source). If the doer is obvious, unknown or unimportant, leave it out — most passive sentences in has text have no by.

How do I form the passive in has perfect tense, like the present perfect?

Keep has / have (the tense of the active verb) and add been + past participle: “They have built the bridge.” → “The bridge has been built.”

Why use the passive rather than the active?

To stress the action or its result rather than the doer — very common in scientific texts, news headlines and reports where the doer is secondary.

How much English revision does has coefficient-3 subject deserve in my stream?

Has regular slot, not an afterthought. Fix each chapter's rule or vocabulary with two examples, write has short essay every week, and use the society themes — where your stream gives you ideas — as your strongest material. Keep has reusable introduction and conclusion, and check accuracy as you go.

Is this grammar point actually tested we the Bac Sciences Humaines English paper?

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