He lost everything.

My boyfriend gave me a gift.

Everyone was surprised by the news.

He is an expert in ethology, and his research is highly regarded worldwide.

He is always cheerful and believes in the proverb 'Fortune comes in by a merry gate.'

Him laughing at other people's mistakes is just like the pot calling the kettle black.

He is behaving like an idiot.

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

The motto of this team is 'one for all, all for one'.

Since he is always laughing, it can be said that 'fortune comes in by a merry gate'.
