My boyfriend gave me a gift.

Everyone was surprised by the news.

What does this at sign mean?

He was injured, so we carried him on a stretcher.

The tanker has entered the port.

Calcium carbide is a major raw material for acetylene gas.

He knows that pain through his own experience.

He is feigning ignorance about that problem.

In order to understand his feelings, I had a deep conversation with him.

God only knows what he is thinking.
