Technical Listening

ការស្តាប់យកព័ត៌មានលម្អិតបែបបច្ចេកទេស

In academic and technical talks, missing one step changes everything. You must listen for sequence and conditions.

សម្រាប់ការណែនាំបែបបច្ចេកទេស ឬការសិក្សា ការខកខានជំហានណាមួយអាចធ្វើឲ្យខុសទាំងស្រុង។ អ្នកត្រូវស្តាប់យក "លំដាប់លំដោយ" និង "លក្ខខណ្ឌ" ឲ្យបានច្បាស់!
➡️

Signposting Flow ➡️

ពាក្យបញ្ជាក់ពីលំដាប់លំដោយ (Sequence)

Listen for words that tell you exactly WHEN an action happens.

Prior to Before a particular time or event. មុនពេល
Subsequently After something else happened. ជាបន្តបន្ទាប់មកទៀត
Simultaneously At exactly the same time. ក្នុងពេលដំណាលគ្នា (ព្រមគ្នា)
⚠️

Conditions & Warnings ⚠️

លក្ខខណ្ឌ និងការព្រមាន

These words alert you that an action depends on a specific rule.

Provided that Only if a condition is met (if). ក្នុងលក្ខខណ្ឌដែលថា... / លុះត្រាតែ...
Unless Except if (if not). លើកលែងតែ...
Failure to Not doing something that is required. ការខកខានក្នុងការ...

Technical Verbs ⚙️

កិរិយាសព្ទបច្ចេកទេស

Action words commonly used in manuals, labs, and academic essays.

Compile To put together from different sources. ចងក្រង (ទិន្នន័យ/ឯកសារ)
Calibrate To adjust a measuring instrument accurately. ថ្លឹងថ្លែងឱ្យច្បាស់លាស់ / ချိန်ឧបករណ៍
Assemble To fit the parts of something together. ដំឡើង / បំពាក់គ្រឿងបន្លាស់
The Timeline Trap!

Don't follow the order of words. Follow the grammar!

(កុំស្តាប់តាមលំដាប់ពាក្យដែលគេនិយាយ ត្រូវស្តាប់វេយ្យាករណ៍! ជួនកាលពាក្យដែលគេនិយាយមុន គឺជាសកម្មភាពដែលត្រូវធ្វើក្រោយ!)
"Before you press the button, you must calibrate the machine."
Step 1: Calibrate ✅
Step 2: Press the button ✅

Is "Subsequently" the same as "Consequently"? They sound similar.

Great question! They are different. "Subsequently" just means it happened NEXT in time (បន្ទាប់មក). "Consequently" means it happened as a RESULT of the first action (ជាលទ្ធផល/ដោយហេតុនេះ). ⏰ vs 💡

Can I use "Prior to" instead of "Before" every time?

Grammatically, yes! However, "Prior to" is very formal. You wouldn't say "I eat breakfast prior to school" in daily life. Use it mainly in academic writing, technical manuals, or professional settings. 👔

I get confused when they say "before X, do Y". How do I stop getting it wrong in the listening test?

That is a classic IELTS/TOEFL trap! When you hear "before" or "prior to", write down the two actions immediately, then draw an arrow. (Action Y) ➡️ (Action X). Don't trust the order you hear the words! 📝
