IELTS Writing for PhD applicants: How to Fix Limited or repetitive trend vocabulary in Task 1

Learn a compact set of verbs and nouns for change (rise, climb, fall, decline, fluctuate, level off) and degree adverbs (sharply, steadily, slightly). Vary them accurately instead of repeating 'increase' and 'decrease'.

At a glance

For: PhD applicants
Problem: Limited or repetitive trend vocabulary in Task 1
Scoring criterion: Lexical Resource
Task affected: Task 1 (Academic report)
IELTS test: Academic
Typical effort: one to two weeks
First step: Build a table of five verbs and five nouns for change, with matching degree words.

Why this happens to PhD applicants

Task 1 language is repetitive by nature. Candidates repeat the same two verbs and the same structure, so Lexical Resource stays limited, even when the description is correct.

Why this affects PhD applicants: research writing is cautious and hedged, which can make a Task 2 position look uncommitted.

Discipline vocabulary can crowd out simple natural language in general topics.

A strength to build on: Practice with structured argument and evidence is already strong.

Fix it in four steps

Build a table of five verbs and five nouns for change, with matching degree words.
Learn both forms: 'sales rose sharply' and 'there was a sharp rise in sales'.
Choose different verbs for different shapes (peak, trough, plateau).
Avoid repeating the same verb in consecutive sentences.

Before and after

Before

The figure increased. Then it increased again. Then it decreased.

After

The figure climbed steadily, reached a peak in 2010 and then fell sharply.

Ten-minute drill: Describe one line graph twice, once with verbs and once with nouns, and compare which sounds more natural.

Questions and answers

What is the fastest way for PhD applicants to fix limited or repetitive trend vocabulary in Task 1?

How long does it take PhD applicants to fix limited or repetitive trend vocabulary in Task 1?

Most learners need one to two weeks. Research schedules are flexible but easily crowded out, so fix a weekly timed session.

Describe one line graph twice, once with verbs and once with nouns, and compare which sounds more natural. Research schedules are flexible but easily crowded out, so fix a weekly timed session.

How can PhD applicants tell they have fixed limited or repetitive trend vocabulary in Task 1?

Your report uses at least five different trend expressions with correct forms.

What should PhD applicants know about their IELTS Writing target?

Doctoral programmes and funders set minimum IELTS scores, often with a Writing minimum. Check the departmental and funder rules separately.

Should PhD applicants practise this on Task 1, Task 2 or both?

This is a Task 1 issue for the Academic report. Practise it on charts, maps and processes within about 20 minutes, and spend the time you save on Task 2. Practice with structured argument and evidence is already strong.
