17．Kate Holmes was visiting a friend，old Mrs Sydney．Mrs Sydney had known Kate all her life．She liked to tell Kate about mysteries 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（銅礦）．He bought the land and ran （經(jīng)營）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（信封）．‘This one is for you'，he said‘a(chǎn)nd 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 envelop for Alf had some money and business papers in it．Dan and Alf were each to get about half of Jed's fortune（財富）．They would both be rich．
"Dan had never seen Alf．He had only two clues．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．

分析 凱特擅長解決謎題．Mrs Sydney說了一個故事：Jed回到Michigan發(fā)現(xiàn)了銅礦，成了一名富有的人，他沒有結(jié)婚，他只有一個哥哥，一天，他要死了，他給他的好朋友Dan兩個信封，一個給Dan，一個給哥哥Alf，Dan的信封里是他的醫(yī)院，給了他銅礦和房子，給Alf的信封里是一些錢和公文，Dan和Alf每個人得到Jed一半的財產(chǎn)，但是Dan沒見過Alf，只有一張相片和一個賀卡，根據(jù)賀卡找到了地址，相片是五十年前他們十歲生日的時候拍的，最后找到了Alf．凱特告知答案：相片是五十年前他們十歲生日的時候拍的，那么他和他哥哥是雙胞胎．
解答 81．Kate is good at solving mysterious．細(xì)節(jié)題．根據(jù)第二段You are very good at solving mysteries可知凱特擅長解決迷惑，故答案是Kate is good at solving mysterious．
82．A copper mine．細(xì)節(jié)題．根據(jù)第三段where he found a copper mine（銅礦）．He bought the land and ran （經(jīng)營）the mine and became a very rich man可知是銅礦讓他成了富有的人，故答案是 A copper mine．
83．There was Jed's dying wish．細(xì)節(jié)題．根據(jù)第七段There were his dying wishes in Dan's envelope可知是Jed的遺愿，故答案是 There was Jed's dying wish
84．photo，post card．推理題．根據(jù)第十段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只有兩個線索相片和賀卡，根據(jù)賀卡找到了地址，照片得知兩者是雙胞胎，故答案是photo，post card．
