Our village carpenter (木匠) , John, came one day and made a dining table for my wife.He made it just the right size for the space between the two windows.When I got home that evening, John was drinking a cup of tea and writing out his bill for the job.

　　My wife said to me quietly,“That’s his ninth cup of tea today.”But she said, in a loud voice,“It’s a beautiful table, dear, isn’t it?”

　　“I’ll decide about that when I see the bill.”I said.

　　John laughed and gave me his bill for the work.I read:

　　One dining table 10 November, 1998

　　Cost of wood $17.00

　　Paint $1.50

　　Work, 8 hours ( $1 an hour ) $8.00

　　Total $36.50

　　When I was looking at the bill, John said, “It’s been a nice day, hasn’t it?Quite sunny.”

　　“Yes.”I said.“ I’m glad it’s only the tenth of November.”

　　“Me, too.”said John.“You wait — it’ll be a lot colder by the end of the month.”

　　“Yes,colder — and more expensive! A dining table will be $20 more expensive on November 30, won’t it, John?”

　　John looked hard at me for half a minute.Was there a little smile in his two blue eyes?I gave his bill back to him.

　　“If there isn’t too much trouble, John,” I said,“please add it up again.You can forget the date…”

　　I paid him $26.50 and he was happy to get it.

　　36.Why did John talk about the weather when the writer was looking at the bill?

　　B.Because it was really a fine day.

　　C.Because he wanted the writer to check the bill carefully.
