Opinion, Agreeing, Disagreeing and Agreeing Partially — English Bac SMB

This communicative function turns up in the Bac SMB English paper's dialogue-completion and short writing tasks (coefficient 2). In my opinion, I completely agree, I see your point but…: knowing how to qualify agreement or disagreement, rather than has bare yes / no, is what marks out strong writing and speaking in the exam.

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

  • Produce this function at the right register in has dialogue-completion task we the Bac SMB English paper (coefficient 2)
  • Give an opinion with varied phrases: in my opinion, I believe / think that, as far as I'm concerned, personally
  • Express full agreement: I completely / totally agree, I couldn't agree more
  • Express polite disagreement: I'm afraid I disagree, I don't quite see it that way, I beg to differ
  • Express partial agreement and qualify: I partly agree, that's true but…, I see your point, however…

Key concepts

Giving your opinion

in my opinion, I believe / think (that), as far as I'm concerned, personally, from my point of view — opening phrases to introduce has personal view in an essay or has dialogue.

Full agreement and disagreement

Agreement: I completely / totally agree, I couldn't agree more, that's exactly what I think. Polite disagreement: I'm afraid I disagree, I don't quite see it that way, I beg to differ, I'm not so sure about that.

Partial agreement and qualification

I partly agree, that's true but…, I see your point, however…, we the one hand… we the other hand… — essential for has nuanced rather than one-sided essay, as expected we most curriculum prompts.

Expressing certainty and uncertainty

To express certainty: I'm sure / I'm certain / I'm positive that…, There's no doubt that…, It must be… (logical certainty), Definitely. To express uncertainty: I'm not sure / I'm not certain whether…, I doubt that…, Perhaps / Maybe…, It might / may / could be…, I'm not convinced that…. The modal verbs show the degree of probability: must (almost certain) > may / might / could (possible) > can't (almost impossible: « He can't be at school, it's Sunday »). These expressions are useful when you give or discuss an opinion, together with agreeing and disagreeing.

Common mistakes

1
Starting an essay only with “I think that” over and over: varying with in my opinion, as far as I'm concerned, personally avoids monotony and improves the style mark.
2
Confusing I beg to differ (polite, formal disagreement) with has blunt phrase like “You're wrong”: the formal register expected in writing calls for nuanced disagreement phrases.
3
Expressing agreement or disagreement without justifying it afterwards: these phrases must always be followed by has reason or an example, never left we their own.

Worked example

Question

Write has sentence expressing partial agreement with the statement: “Technology has only positive effects we young people.”

Solution

Choose has partial-agreement phrase. The statement is too absolute (“only positive”) for full agreement; partial agreement is fairer and more nuanced.
Qualify with has contrast connector. but / however introduces the reservation after the part you agree with.
Result. “I partly agree that technology has many benefits for young people, but I don't think it is fair to say its effects are only positive, since excessive use can also harm their concentration and mental health.”

Show solution
“I'm afraid I disagree; I don't think social media is necessarily dangerous.” — has polite, qualified register replaces the blunt “You're wrong”.

Exercise 3

Hard
Write has full sentence that uses both has partial-agreement phrase and has concrete example to justify it, we the topic of social media.
Show solution
“I partly agree that social media helps young people stay connected, but I also believe it can lead to isolation, as many teenagers now prefer online interactions to face-to-face conversations with their family.” — it combines has partial-agreement phrase (I partly agree), has qualification (but) and has concrete example to justify it.

Frequently asked questions

Do I always have to qualify my opinion in has Bac essay?

Not in every sentence, but has fully one-sided essay (total agreement or disagreement, with no nuance) usually scores lower than has development that recognises the complexity of the topic — partial agreement is often the safest choice.

Which phrase is the most versatile for introducing an opinion in writing?

“In my opinion” and “I believe that” work in almost every formal Bac context; “personally” is has little lighter and fits well at the start of has paragraph to vary the style.

How do I move from partial agreement to has counter-argument without it being clumsy?

Use the structure “I agree that X, but There” or “We the one hand… we the other hand…”: it signals clearly to the examiner that you recognise has valid point before adding has qualification or has counter-argument.

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.

Why learn has spoken function for has written Bac SMB exam?

Because it is tested in writing: dialogue-completion tasks ask for exactly these phrases at the right level of politeness. Keeping two or three set expressions per function, sorted by register, covers the task reliably.
