live in the mountains of the eastern USA speak with an older kind of English dialect. When Americans moved from one place to another, they took their dialects with them. So people from the mountains in the southeastern USA speak with almost the same dialects as people in the northwestern USA. The USA is a large country in which many different dialects are spoken. Although many Americans move a lot, they still recognize and understand each other’s dialects. THE OXFORD ENGLISH DICTIONARY You may think that English dictionaries have been used for many, many centuries. The spelling of English has always been a problem but it was more of a problem in the days before a dictionary. Then people could spell word in different ways which you might find it interesting. But it made reading English much more difficult. So dictionaries were invented to encourage everybody tospell the same. In fact, an English dictionary like the kind you use today wasn’t made until the time of the late Qing Dynasty. There men did most of the important early work on dictionaries: Samuel Johnson, Noah Webster, and James Murray. These men spent nearly all of their lives trying to collect words for their dictionaries. For them, it wasn’t only a job; it was a wonderful journey of discovery. The largest dictionary in the world is the Oxford English Dictionary, or OED for short. The idea for this dictionary came from an important meeting in Britain in 1857. Twenty-two years later, Oxford University asked James Murray to be the editor of its new dictionary.Murray had never been to college. At the age of fourteen, he left his village school in Scotland and taught himself while working in a bank. Later he became a great teacher. After Oxford gave him the job, Murray hada place built in the garden behind his house to do his work. Part of it was one meter underground. In winter it felt like a barn, he had to wear a heavy coat and put his feet in a box to keep warm. Every morning, Murray got out of bed at five o’clock and worked several hours efore breakfast. Often he would work by the candle light into the evening. Murray hoped to finish the new dictionary in ten years. But after five years, he was still adding words for the letter A! then others went to work with Murray, including his two daughters. He worked on the dictionary until he was very old. Forty-four years later, in1928, other editors finished it. It included more than 15,000 pages in twelve books. And you thought your dictionary was big! Unit 3 JOURNEY DOWN THE MEKONGPART 1 THE DREAM AND THE PLAN My name is Wang Kun. Ever since middle school, my sister Wang Wei and Ihave dreamed about taking a great bike trip. Two years ago she bought an expensive mountain bike and then she persuaded me to buy one. Last year, she visited our cousins, Dao Wei and Yu Hang at their college in Kunming. They are Dai and grew up in western Yunnan Province near the Lancang River, the Chinese part of the river that is called the Mekong River in other countries. Wang Wei soon got them interested in cycling too. After graduating from college.we finally got the chance to take a bike trip. I asked my sister, \e we going?\my sister who first had the idea to cycle along the entire Mekong River from where it begins to where it ends. Now she is planning our schedule for the trip.I am fond of my sister but she has one serious shortcoming. She can be really stubborn. Although she didn't know the best way of getting to places, she insisted that she organize the trip properly. Now, I know that the proper way is always her way. I kept asking her, \e we coming back?\er whether she had looked at a map yet. Of course, she hadn't; my sister doesn't care about details. So I told her that the source of the Mekong is in Qinghai Province. She gave me a determined look—the kind that said she would not change her mind. When I told her that our journey would begin at an altitude of more than 5,000 metres, she seemed to be ex about it. When I told her the air would be hard to breathe and it would be very cold, she said it would be an interesting experience. I know my sister well.

We found a large atlas with good maps that showed details of world geography. From the atlas we could see that the Mekong River begins in a glacier on a Tibetan mountain. At first the river is small and the water is clear and cold. Then it begins to move quickly. It becomes rapids as it passes through deep valleys, travelling across western Yunnan Province. Sometimes the river becomes a waterfall and enters wide valleys. We were both surprised to learn that half of the river is in China. After it leaves China and the high altitude,the Mekong becomes wide，brown and warm. Ascited it enters Southeast Asia, its pace slows.

It can only be seen outside the palace on special days. We ate an early supper and went to see a great temple with floors made of sliver. The next morning our group slept late.

财政部财建[2009]129号文件《太阳能光电建筑应用财政补助资金管理暂行办法》，对于太阳能光伏并网发电站，2009年补助标准原则上定为20元/Wp。
太阳能是一种清洁、可再生能源，因为实现了直接将太阳能转化为电能而受到世界各国的重视。作为可再生能源当中最具潜力的新能源，光伏能源的重要性和战略性得到进一步凸显。光伏产业是二十世纪80年代后世界上增长最快的高新技术产业之一。最近十年平均增长率为33%，最近五年平均增长率为43%。2004年光伏市场的发展更是超过了工业历史上有过的任何一次飞跃，其增长率达到61.2%，太阳能电池总产量达到了创纪录的1194 MW！随着京都协议的签署和实施以及2002年8月在非洲约翰内斯堡召开的人类可持续发展高级论坛会，专家预测：光伏发电将在二十一世纪前半期超过核电成为最重要的基础能源，至少到2010年世界太阳能电池制造产业仍将保持30％以上的增长速度。现在，各国政府已将发展可再生能源列入议事日程并纷纷推出各国到2010年新能源发展计划：

There men did most of the important early work on dictionaries: Samuel Johnson, Noah Webster, and James Murray. These men spent nearly all of their lives trying to collect words for their dictionaries. For them, it wasn’t only a job; it was a wonderful journey of discovery. The largest dictionary in the world is the Oxford English Dictionary, or OED for short. The idea for this dictionary came from an important meeting in Britain in 1857. Twenty-two years later, Oxford University asked James Murray to be the editor of its new dictionary.Murray had never been to college. At the age of fourteen, he left his village school in Scotland and taught himself while working in a bank. Later he became a great teacher. After Oxford gave him the job, Murray hada place built in the garden behind his house to do his work. Part of it was one meter underground. In winter it felt like a barn, he had to wear a heavy coat and put his feet in a box to keep warm. Every morning, Murray got out of bed at five o’clock and worked several hours efore breakfast. Often he would work by the candle light into the evening. Murray hoped to finish the new dictionary in ten years. But after five years, he was still adding words for the letter A! then others went to work with Murray, including his two daughters. He worked on the dictionary until he was very old. Forty-four years later, in1928, other editors finished it. It included more than 15,000 pages in twelve books. And you thought your dictionary was big! Unit 3 JOURNEY DOWN THE MEKONGPART 1 THE DREAM AND THE PLAN My name is Wang Kun. Ever since middle school, my sister Wang Wei and Ihave dreamed about taking a great bike trip. Two years ago she bought an expensive mountain bike and then she persuaded me to buy one. Last year, she visited our cousins, Dao Wei and Yu Hang at their college in Kunming. They are Dai and grew up in western Yunnan Province near the Lancang River, the Chinese part of the river that is called the Mekong River in other countries. Wang Wei soon got them interested in cycling too. After graduating from college.we finally got the chance to take a bike trip. I asked my sister, \e we going?\my sister who first had the idea to cycle along the entire Mekong River from where it begins to where it ends. Now she is planning our schedule for the trip.I am fond of my sister but she has one serious shortcoming. She can be really stubborn. Although she didn't know the best way of getting to places, she insisted that she organize the trip properly. Now, I know that the proper way is always her way. I kept asking her, \e we coming back?\er whether she had looked at a map yet. Of course, she hadn't; my sister doesn't care about details. So I told her that the source of the Mekong is in Qinghai Province. She gave me a determined look—the kind that said she would not change her mind. When I told her that our journey would begin at an altitude of more than 5,000 metres, she seemed to be ex about it.

我们国家制定的中长期发展规划提出：2010年光伏发电装机容量达到600MWp；2020年达到1.6GWp。
根据电力科学院的预测，到2050年中国可再生能源发电将占到全国总电力装机的25%，其中光伏发电占到20%。
（2）缓解能源危机的迫切需要
能源危机人类发展所面临的重大挑战之一，据世界能源委员会和国际应用系统分析研究所预测，全球化石燃料总量只够用100年左右。
目前，人类使用的能源最主要是非再生能源，如石油、天然气、煤炭和裂变核燃料约占能源总消费量的90％左右，再生能源如水力、植物燃料等只占10％左右。 世界能源储量最多是太阳能，在再生能源中占99.44％，而水能、风能、地热能、生物能等不到1％。在非再生能源中，利用海水中的氘资源产生的人造太阳能（聚变核能）几乎占100％，煤炭、石油、天然气、裂变核燃料加起来也不足千万分之一。所以，人类使用的能源归根到底要依靠太阳能，太阳能是人类永恒发展的能源保证。 世界能源储量分布是不平衡的。石油储量最多地区是中东占56.8%；天然气和煤炭储量最多是欧洲，各占54.6%和45%。亚洲大洋洲
