Task 2 · Cross-cutting skill

Sentence types — the skill, not the paragraph

This does one job: it varies the shape of your sentences for a reason, instead of writing every sentence the same way. Throughout both tasks. Grammatical Range is assessed on whether you can handle different structures accurately — not on whether every sentence is long, which is the misreading that produces most of the errors in this area.

What sentence types really asks you to do

Sentence variety means choosing simple, compound or complex structures according to what the sentence has to do — not alternating them to look varied.

Range is not length

The criterion asks for a range of structures used accurately, and it is read as “write longer sentences” more often than any other instruction in the exam. The result is predictable: writers stack subordinate clauses onto sentences that were working, and the errors they introduce cost more than the range they gained. A response of accurate simple and compound sentences scores better than one of ambitious complex sentences with agreement errors in them.

Each shape does something the others cannot. A simple sentence lands a point — it is the right structure for a thesis, and for the sentence you most want the reader to remember. A compound sentence balances two things of equal weight. A complex sentence subordinates: it says explicitly that one part matters more than the other, which is why it is the natural shape for a concession or a cause.

The practical consequence is that variety follows from function. If your paragraph has a claim, a reason, a concession and a consequence, the sentences will vary on their own, because those four jobs do not fit the same shape. Variety pursued directly — long, short, long, short — produces sentences whose form has nothing to do with their content, and readers feel that even when they cannot name it.

Simple = emphasis

One clause, no subordination. The right shape for a thesis and for the line you want remembered.

Compound = balance

Two independent clauses joined by “and”, “but”, “so”. Equal weight on both sides.

Complex = hierarchy

One clause subordinated to another. It says which half matters more, which is why concessions take this shape.

Accuracy first

An accurate simple sentence beats an ambitious complex one with an agreement error in it.

What it costs you to skip this

A response written entirely in one shape reads as monotonous and caps Grammatical Range regardless of how accurate it is. Pursuing variety for its own sake costs the other way: subordinate clauses added to sentences that did not need them introduce errors into paragraphs that had none, and they usually arrive in the last five minutes when there is no time to check them.

Where it stops applying

Sentence variety cannot rescue an idea that is not there — a badly reasoned paragraph in beautifully varied sentences is still a badly reasoned paragraph. And a short sentence is not a defect: replacing a clear short one with a long one at the last minute is the most reliable way to add an error to a paragraph that was already correct.

Examples · watch, then the mistakes

The skill working, and the two ways it fails

Worked example · simple, then complex

Restriction works. It works because the alternative — pricing by fuel duty — spreads the cost across drivers who have no way to avoid it, whereas a zone charge falls on a choice.

Why it works: The short sentence lands the claim and the long one explains it. The contrast in length is doing work: the reader knows which of the two sentences is the point.

Worked example · complex + compound

Although the scheme raised costs for some households, it reduced them for the majority, and the net effect was a fall in average spending.

Why it works: The subordinate clause concedes, the main clause reverses, and the compound half adds a balanced consequence. Three jobs, three shapes, one sentence.

Although the scheme, which was introduced in 2003 and which had been debated for years, raised costs, it worked.

Two relative clauses stacked inside a concession. The structure is technically correct and the reader has lost the sentence by the time the main clause arrives.

Repaired: The scheme, debated for years before its introduction in 2003, raised costs — and it worked.

Public transport is cheap. Public transport is clean. Public transport is reliable.

Three simple sentences with identical shape and subject. Accurate, and it caps the range criterion by itself.

Repaired: Public transport is cheap and clean, and where it is reliable it competes directly with the car.

Now you try · with the scaffolding on

Build it one step at a time

Give each one the shape its job needs — without adding a clause you do not need.

The material

You have three things to say: (a) free entry works; (b) it costs money; (c) the cost is smaller than the benefit.

Step 1Write (a) as a simple sentence

One clause. This is the point you want remembered, so give it the shape that lands.

4 more words before you can compare. Writing it yourself first is the whole exercise.

Where it is practised

This skill lives in a stage of the essay too

Build the introduction

Where this skill is built into a paragraph, with the rest of the stage around it.

Thesis and position

It states the answer to the question and keeps that answer visible from the first paragraph to the last.

Topic sentences

It opens a paragraph by naming the one claim that paragraph exists to support.

Explanation and development

It takes one claim and follows it, instead of stating four claims and following none.

Examples and evidence

It makes an abstract claim concrete, without pretending to a source you do not have.

Contrast and concession

It admits what is true in the opposing view and then explains why your position survives it.

Critical final review

It checks the four things that can still be fixed, in the order that finds the expensive problems first.
