The Passive Voice — English Bac SMB

ضمن برنامج بكالوريا SMB

English carries a coefficient of 2 in the Bac Sciences Maths B (SMB) stream, level with Philosophy. Mathematics dominates the stream (coefficient 9), followed by Physics-Chemistry and Engineering Sciences (coefficient 7 each), so English can look marginal — but it and Philosophy form the narrow margin where rankings and honours are actually decided. Reading, language and guided writing are all assessed.

في الامتحان

Three parts: Reading Comprehension, Language, and Writing (a guided text of about 180 words). SMB candidates, trained to be rigorous and systematic, do well on the Language section if they treat each grammar point as a rule with a fixed structure; the risk is a dry essay that ignores vocabulary range and register, which the Writing section also scores.

أهداف التعلم

Apply this grammar point accurately in the Language section and in the guided writing of the Bac SMB English exam (coefficient 2)
Transform an active sentence into a 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

المفاهيم الأساسية

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.

الأخطاء الشائعة

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

Using a 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).

مثال محلول

نص السؤال

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

التصحيح

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.”

Easy

Put into the passive: “They deliver the mail every morning.”

“The mail is delivered every morning.” — active present simple → am / is / are + past participle.

“The results will be announced tomorrow.” — active simple future (will + base form) → will be + past participle.

الأسئلة الشائعة

When should I keep the agent with by?

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

How do I form the passive in a 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.

A maths-stream student often dislikes English — how do they raise the mark?

Treat it as structure. Every writing task = introduction + argument + counter-argument + conclusion; every grammar point = one rule + one correct example + one typical mistake. Memorise that framework, apply it to the 31 chapters with two example sentences each, and 12/20 is reachable without eating into the heavy maths programme.

Is this grammar point actually tested on the Bac SMB 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.
