Last night, a large-scale riot broke out in the city.

My mobile phone broke.

He repaired the broken TV.

He dissected a frog in his biology class.

Japan's coastal defense plays a very important role.

He attended a class on dissection.

He broke the promise.

I am majoring in anatomy at university.

He broke the window glass and ran away.

We dream of a day when all people can enjoy world peace.
