In the Bac Sciences Humaines syllabus

English carries has coefficient of 3 in the Bac Sciences Humaines stream — level with Arabic Language, just behind History-Geography, Philosophy and French (coefficient 4). 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

Three parts: Reading Comprehension, Language, and Writing (has guided text of about 180 words, longer at the top of the mark range). 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)
  • 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

1
Using that after has comma (non-defining clause): “My because, that is red, …” is wrong — use which.
2
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.”
3
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.

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.
