An Essay Giving Your Opinion on a Social Issue B2 Writing Practice Tests Rules & Examples

How to Write an Opinion Essay on a Social Issue

An opinion essay is a formal piece of writing in which you clearly state your view on a social issue and support it with well-organised arguments and evidence. This type of writing appears in examinations such as Cambridge B2 First (FCE) and is an essential skill for academic and professional life.

Real-life examples of social issues you might write about include online privacy, the impact of social media on young people, inequality in education, or the environmental responsibilities of large corporations. In each case, your task is to present a reasoned, structured argument — not simply a list of personal feelings.

A strong B2 opinion essay typically follows this structure:

• Introduction: A general statement about the issue and a clear thesis stating your opinion.
• Body Paragraph 1: Your first main argument with a supporting example or evidence.
• Body Paragraph 2: Your second main argument with a supporting example or evidence.
• Body Paragraph 3 (optional): A counter-argument, followed by a rebuttal.
• Conclusion: A summary of your position and a balanced final verdict.

Essential Writing Rules and Sentence Structure

1. Writing a Clear Thesis Statement

Your thesis statement is the single most important sentence in your essay. It appears at the end of your introduction and tells the reader exactly what your opinion is. Avoid vague openings. Compare these two examples:

❌ Social media is a very interesting topic and there are many things to say about it.

✅ It is my firm belief that the unrestricted use of social media poses serious risks to the mental health of young people.

A strong thesis is specific, confident, and uses formal vocabulary. Avoid contractions (do not use don't, can't, it's) and informal expressions.

2. Topic Sentences for Body Paragraphs

Every body paragraph must begin with a clear topic sentence that introduces the argument of that paragraph. The remaining sentences develop, explain, and exemplify that argument.

Formula: Topic Sentence → Explanation → Example or Evidence → Link to thesis

Example topic sentence: One of the most significant concerns regarding social media is its documented effect on adolescent self-esteem.

3. Concession Clauses

At B2 level, you must show that you can acknowledge an opposing view before refuting it. This demonstrates critical thinking and improves your score. Use concession structures such as:

• While it is true that social media connects people globally, it is equally clear that...
• Although some argue that..., the evidence suggests that...
• Despite the benefits that technology brings, there remains...

4. Passive Structures for Formal Register

Use the passive voice to create an objective, academic tone. Avoid writing everything in the first person.

• It has been widely reported that screen time among teenagers has increased significantly.
• It is generally accepted that access to quality education is a fundamental right.
• Research has demonstrated that income inequality continues to widen in many countries.

5. Punctuation with Discourse Markers

When a sentence adverb or discourse marker begins a sentence or clause, it must be followed by a comma. This is one of the most frequently tested punctuation rules at B2 level.

• Furthermore, studies have confirmed a direct link between social media use and anxiety.
• Nevertheless, it would be an oversimplification to blame technology alone.
• Consequently, governments must take immediate action to address this issue.

Useful Linking Words (Connectors)

The following connectors are essential for writing a well-structured B2 opinion essay. Study each one carefully, paying attention to its function and position in the sentence.

Model Writing Sample: Should Social Media Be More Strictly Regulated?

Read the following model essay carefully. Notice how the writer structures each paragraph, uses formal language, and acknowledges a counter-argument before reaching a clear conclusion.

[Introduction]
In recent years, the influence of social media on everyday life has grown at a remarkable rate. While many people regard these platforms as harmless tools for communication, there is mounting evidence to suggest otherwise. It is my firm belief that social media requires far stricter regulation in order to protect users, particularly young people.

[Body Paragraph 1 — First Argument]
One of the most pressing concerns is the well-documented impact of social media on mental health. Research has demonstrated that excessive use of these platforms is closely linked to increased rates of anxiety and depression among adolescents. Furthermore, the algorithms used by social media companies are deliberately designed to maximise engagement, often at the expense of users' wellbeing.

[Body Paragraph 2 — Second Argument and Counter-argument]
In addition to this, the spread of misinformation on social media poses a serious threat to public discourse. Although it is true that these platforms allow individuals to share ideas freely, this freedom has too often been exploited to promote harmful or false content. Consequently, some form of oversight is not only reasonable but essential.

[Conclusion]
Taking everything into account, the risks associated with unregulated social media clearly outweigh any perceived benefits. Governments and technology companies must collaborate to introduce effective safeguards. Only in this way can society ensure that these powerful platforms serve the public good.

Common Writing Mistakes to Avoid

Mistake 1: Comma Splice (Joining Two Main Clauses with Only a Comma)

❌ Social media is harmful, governments should regulate it more strictly.
✅ Social media is harmful; consequently, governments should regulate it more strictly.
Two independent clauses cannot be joined with a comma alone. Use a semicolon, a conjunction, or a discourse marker with correct punctuation.

Mistake 2: Missing Comma After a Sentence Adverb

❌ Furthermore studies have shown a clear link between inequality and poor health outcomes.
✅ Furthermore, studies have shown a clear link between inequality and poor health outcomes.
Discourse markers such as Furthermore, Nevertheless, Consequently, and Moreover must always be followed by a comma when they begin a sentence.

Mistake 3: Confusing 'Despite' and 'In Spite Of' with 'Although'

❌ Despite the government has introduced new laws, the problem continues.
✅ Despite the introduction of new laws, the problem continues.
Despite and in spite of must be followed by a noun phrase or a gerund (-ing form), not a subject + verb clause. Use although or even though when a full clause follows.

Mistake 4: Using Informal or Inconsistent Register

❌ A lot of people think social media is pretty bad for kids and we should do something about it.
✅ It is widely recognised that social media can have a detrimental effect on young people, and it is therefore essential that action is taken.
In a formal opinion essay, avoid colloquial expressions (a lot of, pretty bad, kids, do something). Use formal vocabulary and passive structures to maintain a consistent academic register throughout.
