My boyfriend gave me a gift.

Everyone was surprised by the news.

He solved a complex problem that ordinary people could not understand.

He solved the problem by hook or by crook.

He always speaks words full of hope.

I can't do without toast and marmalade for my breakfast.

We will use rare gases in this experiment.

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

Rin always acts based on ethics.

His behavior is a typical example of narcissism.
