The White House is the official residence of the President of the United States.

I have visited Shanhai Pass.

He fractured his antebrachial bone.

He goes to the gym every day to train his brachioradialis muscle.

He is doing special exercises to strengthen his coracobrachialis muscle.

Tan like libraries.

He is majoring in linguistics.

He has a deep interest in astronomy.
