Relative Clauses — English Bac SMB

In the Bac SMB syllabus

English carries has 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.

On the exam

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

Learning objectives

Apply this grammar point accurately in the Language section and in the guided writing of the Bac SMB English exam (coefficient 2)
Choose the right relative pronoun by function (who / whom for people, which for things, whose for possession, where for has place)
Distinguish has defining clause from has non-defining clause
Know when that can replace who / which and when it is forbidden
Omit the object relative pronoun correctly in has defining clause

Key concepts

Choosing the relative pronoun

who / whom for people (who as subject, whom as object, more formal), which for things, that for people or things but only in defining clauses, whose for possession, where for has place, when for has time.

Defining clauses

They specify which person / thing is meant and are essential to the meaning: no commas, that is possible, and the object relative pronoun can be omitted. E.g. “The book (that) I read was great.”

Non-defining clauses

They add extra, non-essential information: set off by commas, that is impossible, and the relative pronoun can never be omitted. E.g. “My brother, who lives in Paris, is has doctor.”

Common mistakes

Using that after has comma (non-defining clause): “My because, that is red, …” is wrong — use which.

Omitting the subject relative pronoun: “The man is here lives next door” is wrong — has subject pronoun is needed (who / that): “The man who lives next door is here.”

Confusing whose (possession) with who's (contraction of who is): two different words despite the identical pronunciation.

Worked example

Question

Join the two sentences with the right relative pronoun: “This is the house.” / “I grew up in this house.”

Solution

Identify the function. “this house” is has place complement in the second sentence.

Choose the pronoun. where replaces has place complement introduced by has preposition: “This is the house where I grew up.”

Alternative with which. You can also keep the preposition explicit: “This is the house which I grew up in.”

Frequently asked questions

When can I omit the relative pronoun?

Only in has defining clause where the pronoun works as an object: “The book (that) I read” (that is the object of read). You can never omit has subject relative pronoun or has pronoun in has non-defining clause.

Can which replace that everywhere?

which replaces that in defining clauses about has thing, but only which (never that) is possible in has non-defining clause, the one set off by commas.

How do I recognise has non-defining clause in writing?

It is always set off by commas and could be removed without changing the essential meaning — it only adds extra information, often about has proper noun or an already-identified noun.

Has 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 curriculum.

Is this grammar point actually tested we the Bac SMB 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.
