ការផ្សំកិរិយាសព្ទកម្រិតខ្ពស់ (C1 Mastery)

Advanced grammar goes beyond "like doing" or "want to do". You must master Perfect Gerunds, Passive Infinitives, and the dreaded "To as a Preposition" trap.

រចនាសម្ព័ន្ធកិរិយាសព្ទបន្ត (Gerunds) និងកិរិយាសព្ទដើម (Infinitives) កម្រិតខ្ពស់សម្រាប់ការប្រើប្រាស់ជាក់លាក់និងស៊ីជម្រៅ។

⚠️

The "To + -ing" Trap ⚠️

នៅពេលដែល "To" គឺជាធ្នាក់ (Preposition)

Specific Verb/Adj + to + Verb-ing

Sometimes "to" is NOT part of an infinitive, but a preposition. A preposition MUST be followed by a noun or a gerund (-ing).

I object to paying for this. ខ្ញុំជំទាស់នឹងការបង់ប្រាក់សម្រាប់រឿងនេះ។

He confessed to stealing it. គាត់បានសារភាពពីការលួចវា។

ទម្រង់ Perfect (បញ្ជាក់ថាសកម្មភាពកើតមុន)

Use having + V3 or to have + V3 to emphasize that the action is fully completed in the past.

He denied having stolen it. គាត់បានបដិសេធថាខ្លួនមិនបានលួចវាទេ។

The Passive Voice

ទម្រង់ Passive (អកម្ម)

Passive Gerund: being + V3

Passive Infinitive: to be + V3

I hate being interrupted. ខ្ញុំស្អប់ការត្រូវបានគេកាត់សម្ដី។

I expect to be promoted. ខ្ញុំរំពឹងថានឹងត្រូវបានគេដំឡើងឋានៈ។

Semantic Shifts! ⚠️

Go on doing vs. Go on to do

(ពាក្យខ្លះប្តូរអត្ថន័យទាំងស្រុង ពេលប្រើជាមួយ Gerund និង Infinitive)

Go on + V-ing = Continue

"He went on talking for hours."
(បន្តធ្វើសកម្មភាពដដែល: គាត់បន្តនិយាយរាប់ម៉ោង)

Go on + To + V = Move to next step

"He introduced himself, and went on to explain the project."
(ផ្លាស់ប្តូរទៅធ្វើសកម្មភាពបន្ទាប់: ...រួចគាត់ក៏បន្តទៅពន្យល់គម្រោង)

Teacher, I don't understand. Why is it "I want to go" but "I object to going"? They both have 'to'!

This is the ultimate C1 trick! 🪄

In "want to go", the word "to" belongs to the infinitive verb (to go).
But in "object to", the verb is just "object". The word "to" is a preposition (like 'in' or 'at'). And what must come after a preposition? A noun or a gerund (-ing).

Test it: Can you put a noun after it? "I object to *the rules*". Yes! So you must use "-ing": "I object to *going*". 🧠
