Active vs. Passive Voice

ល្បះសកម្ម និង ល្បះអកម្ម

We use the Passive Voice when the action or the object is more important than the person doing it.

យើងប្រើប្រាស់ទម្រង់ Passive Voice នៅពេលដែលសកម្មភាពមានភាពសំខាន់ជាងបុគ្គលដែលជាអ្នកធ្វើសកម្មភាពនោះ។ វាល្អបំផុតសម្រាប់ពន្យល់ពីដំណើរការ ឬច្បាប់ផ្សេងៗ។

Yes, absolutely! It is very polite and professional. For example, saying "Your room is being cleaned" sounds much better than "My staff is cleaning your room right now". hotel

You only use "by" when it is really important to know WHO did the action. Like: "The tour is guided by our expert, Mr. Sok." If it doesn't matter who did it, just leave it out! pedal_bike

Yes! It is the perfect grammar for writing manuals or training guides. "The equipment must be checked", "The reports are filed here", etc. It makes the rules very clear. article
