2.6. The Language Toolkit

In the previous lessons, you learned how to plan an essay, write introductions, build body paragraphs, and link ideas together. But knowing what to say is only half the battle. You also need the language to say it precisely.

This lesson gives you a toolkit of expressions for four essential functions in Task 2 essays:

1. Expressing cause and effect — explaining why something happens and what results
2. Expressing purpose — explaining what something is for
3. Stating and supporting your opinion — making your position clear with reasons, examples, and emphasis
4. Quick reference — a consolidated cheat sheet of every expression, organised by function

This is a reference-heavy lesson. Use it to build your range, then come back to it whenever you need a specific expression.

Section 1: Expressing Cause and Effect

Almost every Task 2 essay requires you to explain causes, effects, or both. The difference between a Band 6 and a Band 7+ answer often comes down to how many different ways you can express these relationships.

There are two fundamental patterns. Every cause-and-effect expression follows one of them.

Pattern 1: Start with the RESULT, look back at the CAUSE

In this pattern, you state the result first and then explain what caused it.

<!-- [DIAGRAM: Two boxes connected by an arrow pointing left (←). The left box is labelled "RESULT" and the right box is labelled "CAUSE". Between them, the arrow is labelled with the connecting expressions: "is due to / owing to / because of / caused by / brought about by / on account of / as a result of". Example sentence below: "High unemployment (RESULT) ← is due to ← the decline of manufacturing (CAUSE)"] -->

Grammar note: These expressions are followed by a noun or noun phrase (not a full clause). Write "due to the decline" — not "due to manufacturing declined."

Pattern 2: Start with the CAUSE, look forward to the RESULT

In this pattern, you state the cause first and then explain the result it produces.

<!-- [DIAGRAM: Two boxes connected by an arrow pointing right (→). The left box is labelled "CAUSE" and the right box is labelled "RESULT". Between them, the arrow is labelled with the connecting expressions: "results in / causes / gives rise to / leads to / brings about / accounts for". Example sentence below: "The decline of manufacturing (CAUSE) → leads to → high unemployment (RESULT)"] -->

Key insight: The same cause-and-effect relationship can always be expressed using either pattern. "Obesity is caused by poor diet" and "Poor diet causes obesity" mean exactly the same thing. Being able to switch between the two patterns gives you flexibility and helps you avoid repetition.

Practice Exercise 2: Paragraph Completion — Overfishing

Complete the paragraph by choosing an appropriate expression for each gap. In most cases, more than one answer is acceptable — the important thing is that the grammar and meaning are correct.

There are a number of reasons why overfishing has reached crisis levels. Firstly, catching large numbers of fish has become very easy [1] modern methods of factory fishing. Secondly, the scarcity of fish [2] higher prices, making fishing more attractive to invest in. This [3] even more fishing and [4] a vicious circle. Furthermore, fishing remains uncontrolled [5] the lack of environmental laws. Finally, where laws do exist they are difficult to enforce [6] the lack of an international maritime police authority.

Section 2: Expressing Purpose

When you propose a solution, describe a process, or explain the function of something, you need purpose language. Purpose expressions answer the question: what is this for? or why is this done?

The Four Core Structures

When to use which:

• to + infinitive is the simplest and most common — use it as your default.
• so that is the only structure that takes a full clause (subject + verb), making it useful when you need to specify who benefits or what changes.
• in order to and so as to are slightly more formal alternatives to "to + infinitive." They are useful for adding variety, especially at the start of a sentence: "In order to address this issue, governments should..."

Two Additional Purpose Expressions

Tip: "In this way" is particularly useful at the start of a sentence following a proposed solution. It lets you explain the intended outcome without repeating the solution itself.

Practice Exercise 3: Rewrite Using Purpose Expressions

Rewrite each sentence using the expression given in brackets. The meaning must stay the same.

a) Governments should invest in public transport. People will then drive less. (so that)

b) Speed cameras are installed on motorways. They slow drivers down. (to)

c) Schools should teach financial literacy. Students will then manage money better as adults. (in order to)

d) Companies are taxed on carbon emissions. This discourages pollution. (so as to)

e) International fishing quotas have been proposed. They would stop the depletion of stocks. (with the purpose of)

Practice Exercise 4: Purpose Paragraph — Overfishing Solutions

Complete the paragraph by filling each gap with an appropriate purpose expression.

Several measures could be taken to address overfishing. Firstly, governments should impose heavy taxes on the fishing industry [1] make it less economically attractive. [2], companies may be less likely to view fishing as easy money. Secondly, stricter environmental laws should be introduced [3] fishing quotas are enforced across international waters. Thirdly, an international maritime police authority could be established [4] monitor and enforce these laws. Finally, consumer awareness campaigns could be launched [5] encouraging the public to buy only sustainably sourced fish.

Section 3: Stating and Supporting Your Opinion

In Task 2, you are almost always asked for your opinion. But stating your opinion is not enough — you also need to clarify it, give reasons, provide examples, and emphasise key points. This section gives you expressions for each of these functions.

Opinion Language: Organised by Function

Variety matters. Using "I think" five times in one essay signals a limited vocabulary. Instead, use "I believe" in the introduction, "In my view" in a body paragraph, and "I am convinced that" in the conclusion. Same meaning, better range.

Introducing Other People's Views: The Passive Construction

In academic writing, you often need to present views that are not your own — the views of "experts," "many people," or "some commentators." In English, there are two ways to do this:

Active voice (informal — names the speaker):

• People say that wind turbines are harmless.
• Experts predict that China will become a leading world power.
• Many people regard the Internet as a force for democracy.

Passive voice (formal — focuses on the idea, not the speaker):

• It is said that wind turbines are harmless.
• It is predicted that China will become a leading world power.
• The Internet is widely regarded as a force for democracy.

The passive constructions are more appropriate for IELTS essays because they sound more formal and objective.

Useful pattern for presenting both sides: Use passive constructions to introduce the opposing view, then switch to active voice for your own opinion.

"It is often argued that technology is harmful to children. However, I believe that the educational benefits outweigh the risks."

This creates a clear contrast between "what others think" and "what I think."

Practice Exercise 5: Active to Passive

Rewrite each sentence using the formal passive construction.

a) People say that smartphones have shortened our attention spans.

b) Many people believe that university education should be free.

c) Experts argue that renewable energy can replace fossil fuels entirely.

d) Some people consider traditional medicine to be more effective than modern medicine.

e) Researchers have shown that exercise reduces the risk of depression.

Practice Exercise 6: Build a Paragraph with Opinion Language

Using the expressions from the table above, write a short paragraph (3-4 sentences) that:

1. States your opinion on whether governments should ban fast food advertising
2. Gives a reason
3. Provides an example
4. Emphasises your point

Example answer:

In my view, governments should ban fast food advertising aimed at children. This is because young people are easily influenced by colourful marketing and are unable to make informed decisions about nutrition. For instance, a study in Australia found that children who watched more television advertisements consumed significantly more junk food. Clearly, if governments are serious about tackling childhood obesity, restricting advertising is a necessary first step.

Notice how each sentence uses a different expression from the toolkit: "In my view" (opinion), "This is because" (reason), "For instance" (example), "Clearly" (emphasis).

Section 4: Quick Reference Tables

Use these tables as a cheat sheet when writing practice essays. The goal is to move beyond "because" and "I think" and use a wider range of expressions naturally.

Cause and Effect

Purpose

Opinion and Position

Other People's Views (Passive)

Contrast and Concession

Addition and Reinforcement

Key Takeaways

• There are two cause-and-effect patterns: Result ← Cause (due to, because of, owing to) and Cause → Result (leads to, causes, results in). Learn both so you can express the same idea in different ways.
• Purpose expressions answer "what for?" — use to, so that, in order to, so as to, and with the purpose of depending on whether the next word is an infinitive, a clause, or a gerund.
• State opinions using varied expressions — not just "I think." Use In my view, I believe that, I am convinced that, and others to show range.
• Use passive constructions (It is said that, It is argued that) to introduce other people's views formally.
• Support every opinion with a reason (This is because), an example (For instance), and where appropriate, emphasis (Clearly, Indeed).
• Keep the Quick Reference Tables handy during practice — the goal is to use these expressions so often that they become automatic.
