Introduction and Paraphrasing

The introduction is the first thing the examiner reads. If you copy the prompt, your Lexical Resource score is affected immediately. Here you learn to paraphrase it with academic precision.

Official format versus WeLearn strategy

Official format: IELTS Academic Writing Task 1 asks you to describe visual information in at least 150 words. The introduction is not a separate official task; it is a strategic part of the response.

WeLearn strategy: We train the introduction as a micro-skill because it reduces literal copying and prepares the overview.

Task 1 visual types

Identify the visual before practising a sub-skill.

The response structure changes with the input: a line graph requires trend language, a table requires grouping, a process requires sequencing and a map requires spatial transformation. This guide connects the official IELTS format with the WeLearn teaching strategy.

Line graph

Changes over time

Overview: Look for the dominant trend, line crossing, peak, fall or convergence.

Body: Group the timeline into meaningful periods: start, rapid change, stability or finish.

rose steadily, peaked at, declined gradually, overtook, remained stable

Bar chart

Comparisons between categories

Overview: Look for the highest or lowest category and the clearest contrast.

Body: Group similar categories instead of describing every bar separately.

higher than, whereas, considerably lower, the largest proportion

Practise this visual type →

Pie charts

Parts of a whole

Overview: Look for the dominant segment and distribution changes when two charts are shown.

Body: Compare large and small proportions without listing every slice.

accounted for, made up, represented, the smallest share

Practise this visual type →

Table

Dense row-and-column data

Overview: Look for extremes, row or column patterns and categories that form groups.

Body: Turn the table into two logical groups before writing.

the figure for, respectively, by contrast, across all categories

Process diagram

Production stages or a cycle

Overview: Mention the number of stages and whether the process is linear or cyclical.

Body: Use the passive voice and chronological order; do not invent reasons.

is collected, is heated, after this, subsequently, finally

Map

Spatial changes over time

Overview: Look for overall development, replacements, expansion or reduction.

Body: Organise the response by zones or by before-and-after changes.

was replaced by, was converted into, to the north of, adjacent to

Practise this visual type →

Mixed chart

Two connected visuals

Overview: Find the relationship between the visuals instead of treating them as separate tasks.

Body: Use one paragraph per visual or group them around a shared relationship.

while, in relation to, this corresponded with, a similar pattern

What is the Introduction?

The Task 1 introduction is a one- or two-sentence paragraph that paraphrases the question prompt. Its only purpose is to tell the examiner what the visual shows, without copying the prompt or mentioning trends and specific figures.

Formula

The [visual type] illustrates / presents / compares / depicts [paraphrased topic] [time period or place, if shown].

✓ Incluir

  • Visual type (line graph, bar chart…)
  • Topic / subject (paraphrased)
  • Time period or place (if shown)
  • Unit of measurement, if essential

✗ Excluir

  • Copied prompt text
  • Trends or comparisons
  • Specific figures or percentages
  • Personal opinions or comments

Paraphrasing techniques

01
Change the main verb

The verb "shows" is simple. Replace it with a more academic synonym. Avoid using "shows" when it already appears in the prompt.

02
Change key nouns

Transform nouns with academic synonyms: percentage → proportion, number → figure, people → population/individuals.

03
Change the sentence structure

Turn gerunds into relative clauses: "people using the internet" → "people who had internet access". You can also use nominalisation: "countries that produce" → "producing countries".

Verbs

shows→ illustrates·presents·compares·depicts·provides data on·displays
show (plural)→ illustrate·present·compare·depict·outline

Nouns

number (of)→ figure·quantity·volume·total
amount→ level·quantity·volume·sum
people→ individuals·the population·residents
countries→ nations·states
types / kinds→ categories·forms·varieties

Time expressions

between X and Y→ from X to Y·over the period X–Y·during the X to Y period
in X years→ over a X-year period·across X years

Examples with authentic-style visuals

Each visual type has three worked examples; the rest are waiting in the practice engine below. Study the prompt, identify the information that must be preserved and compare two valid ways to paraphrase it.

You selected Line graphs. Choose a reference to study its visual and paraphrase with enough space to read both clearly.

Example 01 · Line graphsReference 1 of 3

IELTS reference visual

The prompt · paraphrase this

The line graph below shows the percentage of people with internet access in three regions between 2000 and 2020.

Model A · precise paraphrase

The line graph illustrates the proportion of the population with internet access in three regions over a twenty-year period.

Model B · valid alternative

The chart presents changes in internet access across three regions from 2000 to 2020.

shows → illustrates · percentage → proportion · between X and Y → over a twenty-year period

Progressive engine

Practise the introduction by level

These twelve visuals are the ones the lesson above did not work through, so the answer is not printed anywhere on this page. Each level trains a different decision: first choose the words, then check that the sentence covers the whole prompt, and finally spot what a good-sounding introduction has added.
