问答题中国作为一个发展中国家，很自然十分关心发展中国家在世界经济中所处的困境。许多事实证明，北南关系不是朝着更好的方向发展，而是趋于进一步的恶化。因此，改善北南关系就成为所有国家的一项重要任务。目前，北南之间的差距进一步扩大，富的更富，穷的更穷。许多发展中国家人民正生活在贫困线之下，发达国家有责任给发展中国家以更多的帮助，并同意在平等互利、平等交换的基础上，建立一个新的国际经济秩序。 今天的世界各国，经济上的相互依存更加密切。如果发展中国家的困难长期得不到解决，经济得不到发展，发达国家的经济要持续保持稳定增长，也将是困难的。在商品、贸易、债务、资金、货币和金融等领域，采取有效措施，改善发展中国家面临的外部环境，以利于发展中国家恢复增长和发展，这是当前国际经济领域中的一项紧迫任务。这样做也有利于世界经济的稳定和增长。
问答题西藏旅游：揭去神秘的面纱 西藏地处中国西南部。13世纪中叶，正式纳入中国元代版图。尽管中国历经多次改朝换代，政权更迭，但是，西藏始终在中央政府控制之下，是中国的一个不可分割的部分。 西藏历史文化悠久。考古发掘遗迹表明4000至两万年前就有人栖息于此。勤劳勇敢的西藏人民创造了充满活力、丰富多彩的文化习俗，是一个富于独特的传统文化、能歌善舞的民族。 西藏天文学、历算先进，医学发达，拥有大量经典和文学作品。西藏的艺术瑰宝有绘画、建筑、雕刻、音乐、舞蹈、民间戏剧。西藏各地都有著名的古代艺术景点，其中最著名的景点有布达拉宫、扎什伦布寺、大昭寺和小昭寺等。这里的观光旅游和民俗风情旅游，是世界上最为独特的。 现代游客渴望重返大自然，欣赏大自然。西藏地域广阔、人口稀少，高山白雪皑皑、森林郁郁葱葱、杜鹃满山遍野，河流奔腾不息，湖泊静谧安详。这里绝大多数地方没有污染，散发着淡谈的原始醇香。在这里人们可以尽情地享受大自然的恩赐。

问答题中美合作 中美两国人民的友好合作对世界具有重大影响。美国是最发达的资本主义国家，中国是最大的发展中国家。13亿人口的中国保持稳定和加快发展，对促进亚太地区和世界的稳定与发展，具有极其重要的意义。中国拥有广大的市场和发展需求，美国拥有先进的科学技术和巨大的物质力量，两国的经济有着很强的互补性。中国的潜在市场同国外的先进技术和资金优势结合起来，就能形成众多的发展机遇和强大的发展活力。 中国和美国，在事关人类生存和发展的许多重大问题上，例如维护世界和平与安全，防止大规模杀伤性武器扩散，保护人类生存环境，打击国际犯罪等，有着广泛的共同利益，肩负着共同责任。这些都是中美两国发展友好合作的重要基础。我们应该牢牢把握中美关系的大局，妥善解决分歧，不断朝着增进了解、扩大共识、发展合作、创未来的目标前进。
问答题我们污染了空气 清洁的空气对于健康是至关重要。空气中含有杂质，这些杂质会被我们的身体吸收，使人生病。我们需要清洁的空气，但不幸的是，目前普遍存在着空气污染，尤其是在城市里。 城市里有许多食品厂、服装厂和制造其他东西的工厂。每天这些工厂把千百万吨烟灰排人空气中。燃煤的工厂也大大加重了空气污染。 工厂产生的东西过一个时期就会损坏，然后就作为垃圾扔掉。我们烧掉许多垃圾，烟灰就增多了。还有工厂制造的汽车。汽车一旦出厂在街上行驶，将会吸进空气，排出有毒的气体，并增加空气中的烟尘。 世界上还没有一个彻底摆脱了空气污染的地区。我们必须采取些措施来控制空气污染。 现在越来越多的人认识到清洁的空气的重要性。学校正在把有关污染的问题纳入教学内容。企业界在帮着净化空气，他们安装了特别的设备来清除烟雾。科学家和发明家们正在努力开发更加清洁的汽车和火车引擎，终有一天我们会驾驶着电力汽车，会有一种新型的纸，在水里溶化而不需要燃烧。一些国家正在开发研制一种新型的、会在阳光下溶化和消失的玻璃瓶。 或许，人们在城市里能呼吸新鲜空气的日子将会到来。

问答题中国的环保 我们高度重视资源节约和环境保护，把节能和减排(emission-reduction)作为国家的目标。近两年，又提出并实施节能减排综合性工作方案，建立节能减排指标体系、监测体系、考核体系和目标责任制(a system of accountabifity for reaching the targets)，颁布了应对气候变化国家方案。依法淘汰一大批落后生产能力，关停小型火力发电厂产能(thermal power plants with a total capacity of)2157万千瓦、小煤矿1.12万处，淘汰落后炼铁设施(iron- smelting facilities)产能4659万吨、炼钢产能3747万吨、水泥产能8700万吨。启动十大重点节能工程。中央政府投资支持重点流域水污染防治项目691个。继续推进天然林保护、京津风沙源治理(control the factors causing sandstorms in Beijing and Tianjin)等生态建设，五年累计退耕还林3191万公顷，退牧还草3460万公顷。我们还加强土地和水资源保护。经过各方面努力，节能减排取得积极进展，去年单位国内生产总值能耗(energy consumption per unit of GDP)比上年下降3.27％，化学需氧量(chemical oxygen demand)、二氧化硫(emission of sulfur dioxide)排放总量近年来首次出现双下降，比上年分别下降3.14％和4.66％。节约资源和保护环境从认识到实践都发生了重要转变。
问答题The tiny Isle of Man in the Irish Sea is not known as a vanguard of technology, but this month it was to serve as the test bed for the highly acclaimed third-generation mobile phones. A subsidiary of British Telecom (BT), the British phone company, cobbled together a network and prepared to hand out prototype mobile handsets to about 200 volunteers. But problems arose in the software that keeps track of each call as it moves from one tower’s range to another’s. BT postponed the trial until late summer, after a similar delay announced a few weeks earlier by NTT DoCoMo in Japan. What’s the big deal? Aren’t thousands of mobile calls “handed off” every day from one “cell” to another without a glitch? They are indeed. But third-generation technology, or 3G, is so radically new that it requires a rethinking of just about every aspect of how mobile phones work, from the handset to the transmission masts to the software that runs them. For this reason, 3G are a massive engineering and construction project that will take years to complete and cost hundreds of billions of dollars. The magnitude of this effort has somehow been forgotten in the mad scramble to be first out. The handover problem is a case in point. When you talk on a conventional mobile phone, your call is beamed as a continuous stream of digital data to the nearest receiver. The technology for handing these calls off from one area to the next was worked out years ago. But a 3G phone is different it bundle up the data into little packets and sends them through the airwaves, one at a time. This creates the impression of an Internet connection’s being”always on,” which is good news. But keeping rack of these data bundles from one region to the next is a daunting engineering problem — and, more to the point, a brand-new one. NEC, the Japanese phone company that supplies BT with equipment for its Isle of Man trail, hasn’t had time to work it out. Handset makers also have work to do. The 3G technologies have so many features; only a wonder gizmo could handle all of them, which is why none exists. The phones are not only supposed to work with 3G networks but also with the less sophisticated ( but cheaper and more useful) General Packet Radio Service (GPRS) technology already being installed on the continent and also with the current mobile phone standard, Global System for Mobile (GSM). Phones for corporate executives are also supposed to adapt to dozens of other standards around the world. Doing all this requires powerful, custom-built computer chips, which are tough to make quickly. A device that does so many things is bound to guzzle a lot of power. Prototype 3G phones drain so much juice that they’ve been known to get uncomfortably hot. Batteries that can keep a conventional phone running for days would fizzle in a 3G handset in a matter of minutes. Engineers are searching for alternative, but at the moment the lack of a long-lasting battery is a major hurdle. None of these problems is insurmountable, but neither will they be resolved quickly. Analysts at Forrester Research in the Netherlands predict that even in 2005, when more than half of Europe’s phones will be connected to the Internet, fewer than 15 percent of them will use 3G. That’s a measure of this technology’s complexity and immaturity.
问答题Water Crisis in Spain There’ve been floods, gales and heat waves across Europe-and some lay the blame for the unpredictable weather on climate change. Spain is undergoing its worst drought for sixty years with many areas in the south of the country not seeing a drop of rain for months. Some reservoirs are nearly empty while the volume of water in some rivers is down to a third of its normal level. Guadalajara, in the centre of the country, used to be a prosperous tourist area. Its old Moorish name, ironically, means water running through rocks. But when Emma Jane Kirby visited the small town of Buendia, she found an ecological disaster area in the marketing. There’s a strange smell around the lake at Buendia, the sort of smell that greets you when you first open the fridge after a week or two away from home—a putrid stench of salad leaves that’ve begun to turn to compost in their cellophane bag. I’m reluctant to mention this to my companion, Marco ObisP0 because this after are is the place where he has spent every one of his summer holidays and a just few hours ago we were pouting over the family photograph books while he reminisced wistfully about his idyllic childhood. The problem is I don’t recognize this place as being the same one he showed me in the pictures Those images boasted bronzed children racing joyfully down a bank of emerald green grass towards a vast expanse of water so blue that the cornflower sky above looked dazzled. But this landscape is bleached and barren, the banks crusted white, the ponds patchy and the colour of thin ink. Guadalajara in the centre of Spain has been hit hard by drought. The rains haven’t come since spring last year, leaving the soil parched and lifeless, as cracked and scarred as the face of a small pox victim. The sun has sucked the life from anything that once had the energy to be green and stealthily, its hot tongue has lapped away at the lake’s edge reducing the reservoirs to a fifth of the size they were twenty years ago. As quickly as the water’s evaporated, so have the tourists—the holidaymakers from all over Europe with whom Marco played as a child have been lured away to other areas of Spain where swimming or sailing a boat can be done without fear of scraping knees or hulls on the lake bed. If the landscape is crying out for new water management, then it’s weeping with painful dust-dry tears. North east of Buendia, only the ancient Spanish pine forests seem able to sustain life, some atavistic survival instinct wing them triumph over droughts which long ago killed off the weaker competition. But the trees are now so dehydrated and sapless they’ve become irresistible to fire-two weeks ago, thirteen thousand hectares were lost to a spark from a barbecue-an inferno that also claimed the lives of eleven men. As far as the eye can see now, the hills are almost bare.

问答题春节 中国的春节在农历一月一日，是新一年的开始。这是举家团圆的时刻。一般说来，在春节前几天，只要有可能的话，多数人无论身处何地都会回家。就像圣诞节一样，人们会买很多东西如食品、礼物、衣服和烟花爆竹给孩子们。在除夕之夜，多数农村家庭仍然保持着一些传统习俗，如在两扇门上都贴上门神和春联。他们把“福”字倒贴在墙上和家具的门上，意思是“福到了”。除夕之夜的年夜饭是必不可少的程序。全家人围坐着一张桌子一同分享佳肴，人多的话兴许不止一张桌子。家人还会为没能赶回家的亲人留些座位，仿佛他们也在一起吃似的。年夜饭过后，大家会坐在一起，观看中央电视台的春节特别节目，等待，新年的到来。午夜将近时，特别节目也接近尾声，这时家家户户都到户外去放鞭炮。据说这样可以驱妖除魔。新年的早饭是很特别的，北方人吃饺子，南方人吃糯米饭团。走亲访友从新年的第一天就开始了，俗称“拜年”。每到这时，孩子们是最开心的，因为他们可以从长辈那里拿到压岁钱，据说压岁钱能带给他们好运。新年第五天，人们祭拜财神，送走新年。春节就结束了。
