My boyfriend gave me a gift.

Everyone was surprised by the news.

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.

He is a very excellent technician.

He likes to take a walk in the park at dusk.

We should always remember the power of Kannon in difficult times.

He is the chief technical officer of our company.

This ancient proverb, 'know the other side and yourself, and you will not be in danger in a hundred battles', teaches us the importance of understanding ourselves and others.
