Reading comprehension(阅读理解)：

　　Kate Holmes was visiting a friend, old Mrs. Sydney. Mrs. Sydney had known Kate all her life. She liked to tell Kate about mysteries(神秘故事) and see whether Kate could solve them.

　　“You are very good at solving mysteries,” she said to Kate, “but some day I'll fool you! Maybe I'll be able to fool you today. Did I ever tell you about the story of the Unknown Brother?”

　　Kate said no and listened. She liked Mrs. Sydney's stories.

　　“Well,” Mrs. Sydney said, “Jed Wright was my friend when I was a child. He ran away from home when he was very young and lived for years by doing all kinds of jobs. Finally, in 1927, he went to Michigan, where he found a copper mine(铜矿). He bought the land and ran the mine and became a very rich man.

　　“Jed never married. His parents had died years before, and his only relative was a brother.”

　　“One day Jed knew he was dying. He sent for a good friend, Dan Cole, who had worked for him for years.”

　　“Jed gave Dan two envelopes.‘This one is for you,’ he said, ‘ and please give the other one to my brother Alf. He is…’ While he was speaking, Jed died.”

　　“There were his dying wishes in Dan's envelope. It gave him Jed's mine and house. The envelope for Alf had some money and business papers in it. Dan and Alf were each to get about half of Jed's fortune(财富). They would both be rich.”.

　　“Dan had never seen Alf. He had only two clues(线索). One was an old photo that showed Alf and Jed. But it was taken on their tenth birthday, fifty years ago. The other clue was a post card from Alf. It had no address. It had been mailed in Boston the month before Jed died.”

　　“Dan went to Boston. He put an advertisement in the newspaper. It said there was good news for Alf Wright. It told where Dan was staying.”

　　“The next day, more than a hundred men came to Dan's hotel. They all said they were Alf Wright. But though he had never seen Alf, Dan was able to pick him out right away.”

　　When Mrs. Sydney finished her story, she smiled.

　　“All right, Kate,” she said. “How did he know Alf?”

　　Kate smiled too. “That's easy,” she said. “You told me how. The clue was the photo.”

　　“Yes, it was,” said Mrs. Sydney. “But it was taken when Alf and Jed were boys. How could that help?”

　　“You said it was taken when both boys were ten years old, so they were…”

　　Kate gave Mrs. Sydney the answer and she had to admit that Kate Holmes had won again.
