苍蝇 (cāng ying): комнатная муха

On a hot summer day, the kitchen window was open, and a fly flew in and landed on the freshly cut watermelon.

He was taking a nap, but a fly kept buzzing around his ear, making so much noise that he couldn't sleep.

The restaurant failed its hygiene inspection because several flies were found in the kitchen, so the owner had to close temporarily for cleaning.

Grandpa picked up the flyswatter, quietly walked over to the table, and killed the fly with one swat.

The garbage bag wasn't tied tightly and attracted many flies, so Mom told me to take it out and throw it away right away.

During the exam, a fly kept bumping against the window; though the sound wasn't loud, it distracted a few students in the quiet classroom.
