He injured his foot.

A pen fell from his notebook.

He cut the apple.

The thicket of common reeds is swaying in the wind.

The leaves of the reed are dancing in the autumn wind.

I am practicing the flutter kick in the pool.

His foot is very fast.

I bought three pairs of new socks.

He lost his important limb, the right arm, in an accident.

His legs can run very fast.
