16、One day Mr. Parker said to himself, "I haven't seen my brother David _ _ 21 _ _ a long time, and he's living in a new house now. I'm going to drive there and see him this afternoon."
He took his brother's address, got into his car and started out. He drove for a long time, but he didn't find the house _ _ 22 _ _ he stopped and asked somebody to help him.
"Go straight _ _ 23 _ _ this road for two miles（英里）," the man said, "then turn left, and then take the second road on the right."
Mr. Parker went straight along the road and turned left after two miles, but then he got lost again. He drove for _ _ 24 _ _ mile, and at last he saw a road on his right and stopped. A woman was coming _ _ 25 _ _ him, so he said to her, "Excuse me, is this the second road on the right?"
