Bill is my best friend.

We started walking towards the terminal building.

My office is on the third floor of that mixed-use building.

He was looking for something in the abandoned building.

He caught fish in the river using a fish-trap.

He is a very excellent technician.

The advancement of science and technology has greatly changed our lives.

He is good at solving technical problems.

Information technology plays a very important role in modern society.
