     Some time ago, I discovered that one of my chairs had a broken leg. I didn't think there would be any

difficulty in getting it mended, as there are a whole lot of antique (古董) shops near my home. So I left home

one morning carrying the chair with me. I went into the first shop expecting a friendly reception (接待). I was

quite wrong. The man wouldn't even look at my chair.

    The second shop, though slightly more polite, was just the same, and the third and the fourth-so I decided

that my approach must be wrong.

    I went into the fifth shop with a plan in my mind. I placed the chair on the floor and said to the shopkeeper, "Would you like to buy a chair?" He looked it over carefully and said, "Yes, not a bad chair. How much do you

want for it, Sir?" "20 pounds," I said, "OK," he said, "I will give you 20 pounds." "It's got a slightly broken leg,"

I said. "Yes, I saw that, it's nothing." 

    Everything was going according to the plan and I was getting excited. "What will you do with it?" I asked.

"Oh, it will be easy to sell once the repair is done." "I will buy it," I said. "What do you mean? You have just

sold it to me," he said. "Yes, I know. But I have changed my mind. I am sorry; I will give you 27 pounds for

it." "You must be crazy," he said. Then, suddenly the penny dropped. "I know what you want. You want me to

repair your chair." "You are right," I said. "And what would you have done if I had walked in and said 'would

you mend this chair for me?'" "I wouldn't have agreed to do it," he said. "We don't do repairs, not enough

money in it and too much trouble. But I will mend this for you, shall we say for a five?" He was a very nice

man and was greatly amused by the whole thing.

中国青藏铁路首条延伸线----拉萨至日喀则段于2010年9月底正式开工建设，拉日铁路将带动西藏第二大城市—日喀则旅游业的发展，而实现火车开往加德满都的梦想，也更近一步了。阅读材料回答。

材料一：“十一五”时期西藏自治区向小康西藏、平安西藏、和谐西藏、生态西藏建设迈出了重大步伐、取得了显著成就。这些成就的取得，是党中央高瞻远瞩、亲切关怀的结果；是全国人民深情厚谊、支持帮助的结果；也是全区各族人民上下一心、团结努力、艰苦奋斗的结果。

材料二：随着美国总统奥巴马访问印度，有关中国与印度关系的话题随即又被西方舆论提起。中印之间有分歧，但不能掩盖两国之间存在共同利益诉求的事实。中印同为世界上经济发展最快的新兴国家，在推动建立国际政治经济新秩序上有相似的诉求，在维护亚洲乃至世界的和平、稳定与繁荣上有共同的利益，而且两国都有在地区和国际事务中建立更加密切和广泛的理解与合作的愿望。客观地说，中印在政治上是合作高于对抗，在经贸上是互补大于竞争，在文化上是亲缘多于冲突。片面强调共同利益不现实，而单方面放大分歧也不明智。

结合材料二，说明西藏“十一五”期间取得显著成就给少数民族地区发展的政治启示。

A.发展先进生产力
