Two small mistakes cost more marks in PTE writing than almost anything else: writing the + adjective + of instead of the + noun + of, and choosing the wrong preposition after a noun or adjective. The important of education, the beneficial of green technology, the need of change and capable of reduce pollution all come from knowing the word but not the pattern.
This quiz drills the patterns themselves. It has 86 multiple-choice questions in seven rule groups, and you can practise any single group from the Coverage panel. Every answer shows the rule and the wrong version side by side, and your wrong answers are stored on your own device for seven days so you can retake only what you missed.
The eight groups: 1 adjective to noun conversion · 2 nouns that do not take of · 3 what follows a preposition · 4 infinitive to versus preposition to · 5 adjective + preposition · 6 reporting structures for summaries · 7 the impact / effect of X on Y essay frame.
The One Rule That Fixes Most of These Mistakes
THE + NOUN + OF — never the + adjective + of.
✓ the importance of education the benefits of green technology the effectiveness of the policy
the important of education the beneficial of green technology the effective of the policy
A second rule follows from it: after of – or after any preposition – use a noun, a pronoun or a verb + ing, never a base verb. So it is the importance of protecting the environment, not the importance of protect the environment.
1. Adjective to Noun Conversion Table
| Adjective | Correct noun phrase | Example |
|---|---|---|
| important | the importance of | the importance of education |
| significant | the significance of | the significance of green technology |
| beneficial | the benefits of | the benefits of public transport |
| advantageous | the advantages of | the advantages of renewable energy |
| disadvantageous | the disadvantages of | the disadvantages of fossil fuels |
| effective | the effectiveness of | the effectiveness of urban policies |
| necessary | the necessity of | the necessity of environmental protection |
| possible | the possibility of | the possibility of reducing pollution |
| difficult | the difficulty of | the difficulty of changing public behaviour |
| sustainable | the sustainability of | the sustainability of urban development |
2. Nouns That Do Not Take "of"
This is where a good strategy goes wrong. Not every noun takes of – memorise these as complete phrases.
| Correct | Incorrect |
|---|---|
| ✓ the need for change | the need of change |
| ✓ the reason for pollution | the reason of pollution |
| ✓ the solution to the problem | the solution of the problem |
| ✓ the effect on the environment | the effect to the environment |
| ✓ the relationship between pollution and health | the relationship of pollution and health |
| ✓ an increase in pollution | an increase on pollution |
| ✓ a reduction in emissions | a reduction on emissions |
| ✓ an improvement in air quality | an improvement to air quality |
| ✓ the demand for energy | the demand of energy |
| ✓ the response to the problem | the response of the problem |
| ✓ the approach to the problem | the approach of the problem |
| ✓ the barrier to change | the barrier for change |
| ✓ the problem with private cars | the problem to private cars |
| ✓ the impact of X on Y | the impact of X to Y |
3. Adjective + Preposition Groups
| Preposition | Adjectives | Examples |
|---|---|---|
| for | necessary, important, beneficial, useful, suitable, responsible, essential, harmful | Education is necessary for development. Cars are responsible for some emissions. |
| to | harmful, beneficial, important, similar, related, relevant, essential, opposed | Pollution is harmful to health. This system is similar to the previous one. |
| in | interested, successful, effective, involved, experienced | The policy was effective in reducing emissions. |
| of | aware, capable, afraid, proud, characteristic | Technology is capable of improving productivity. |
| on | dependent, based, focused, reliant | The report is based on scientific evidence. |
| with | associated, connected, concerned, consistent, satisfied | Air pollution is associated with health problems. |
| from | different, separate, protected, free | Renewable energy is different from fossil-fuel energy. |
Two pairs worth knowing exactly: important for = needed to achieve a result (Education is important for economic development), while important to = personally valued (Education is important to students). And although harmful for exists, harmful to is the natural choice for health and the environment.
4. "To" Has Two Different Jobs
| Job | Pattern | Examples |
|---|---|---|
| Infinitive to | to + base verb | need to revise · aim to reduce · decide to change · attempt to solve |
| Preposition to | to + noun / verb-ing | contribute to development · contribute to improving society · lead to pollution · the key to achieving success |
✓ Governments need to reduce pollution. (infinitive)
✓ Green technology contributes to reducing pollution. (preposition)
Green technology contributes to reduce pollution.
5. Reporting Structures for Lecture Summaries
| Structure | Pattern | Example |
|---|---|---|
| Emphasize the importance of | S + emphasized + the importance of + N / -ing | The speaker emphasized the importance of using green technology. |
| Discuss the significance of | S + discussed + the significance of + N / -ing | The speaker discussed the significance of urban development. |

The safe summary formula
Subject + reporting verb + the + noun + of + noun / -ing.
The speaker emphasized the importance of using green technology.
The lecturer discussed the advantages of developing renewable energy.
The presentation explained the disadvantages of depending on private vehicles.
