4 General Motors and Honda ceased production of batterypowered cars in 1999, to focus on fuel cell and hybrid electric gasoline engines, which are more attractive to the consumer. Ford has now announced it will do the same. Three years ago, the pany introduced the Think City twoseater car and a golf cart called the THINK, or Think neighbor. It hoped to sell 5,000 cars each year and 10,000 carts. But a lack of demand means only about 1,000 of the cars have been produced, and less than 1,700 carts have been sold so far in 20xx. “The bottom line is we don‟t believe that this is the future of environment transport for the mass market,” Tim Holmes of Ford Europe said on Friday. “We feel we have given electric our best shot.” The Think City has a range of only about 53 miles and up to a sixhour battery recharge time General Motor‟s EVI electric vehicle also had a limited range, of about 100 miles. The very expensive batteries also mean electric cars cost much more than petrolpowered alternatives. An electric Toyota RAV4 EV vehic le costs over $42,000 in the US, pared with just $17,000 for the petrol version. Toyota and Nissan are now the only major auto manufacturers to produce electric vehicles. “There is a feeling that battery electric has been given its chance. Ford now has to move on with its hybrid program, and that is what we will be judging them on,” Roger Higman, a senior transport campaigner at UK Friends of the Earth, told the Environment News Service. Hybrid cars introduced by Toyota and Honda in the past few years have sold well. Hybrid engines offer greater mileage than petrolonly engines, and the batteries recharge themselves. Ford says it thinks such vehicles will help it meet planned new guidelines on vehicle emissions in the US. However, it is not yet clear exactly what those guidelines will permit. In June, General Motors and Daimler Chrysler won a court injunction, delaying by two years Californian legislation requiring carmakers to offer 100,000 zeroemission and other lowemission vehicles in the state by 20xx. Car manufactures hope the legislation will be rewritten to allow for more lowemission, rather than zeroemission, vehicles. 第二篇 世界原油产量可能提前十年达到峰值 科威特科学家预测世界常规原油产量将在 20xx 年达到峰值，这一发现可能会促进储存石油的努力。 这一预测比其他预测提前了将近十年，已经发表在美国化学学会《能量与燃料》杂志上。 伊布赫姆纳夏威和同事们指出，全球石油消耗的快速增长使人们对“石油峰值”预测的兴趣越来越浓。 “石油峰值”指的是石 油产量达到最大值后开始下降的时间点。 科学家已经构建了几个模型来预测这一时间，有些模型认为这一时间在 2020 年或更晚。 其中最著名的预测模型之一是赫伯特模型。 赫伯特模型认为世界石油产量呈钟形曲线，与此相关的概念是“石油峰值”。 这一术语指的是世界石油产量达到峰值的那一刻，之后将呈现无法逆转的下降趋势。 赫伯特模型精确地预测到美国石油产量于 1970 年达到峰值。 这一模型从此受到欢迎，已经用于预测世界石油生产。 但是，最近研究表明，这一模型不足以解释某些国家更加复杂的石油生产周期。 科学家称，这些生产周期受到技术变化、政 策和其他因素的很大影响。 最近研究描述了赫伯特模型的新版本，提供了更加实际、更加准确的石油生产预测。 科新东方在线 [ ] 20xx 职称英语强化班网络课堂电子教材系列 阅读理解中文朗读 5 学家使用新模型评估了 47 个主要产油国家的石油生产趋势，这 47 个国家是世界常规原油的主要提供者。 科学家预计全球常规原油产量将于 20xx 年达到峰值，比之前预计的要早很多年。 科学家还指出，世界石油储量正在以 %的速度逐年减少，他们认为新模型会帮助做出与能源相关的决定，帮助进行国家政策辩论。 World Crude Oil Production May Peak a Decade Earlier Than Some Predict In a finding that may speed efforts to conserve oil, scientists in Kuwait predict that world conventional crude oil production will peak in 20xx. This prediction is almost a decade earlier than some other predictions. Their study is in ACS39。 Energy amp。 Fuels1. Ibrahim Nashawi and colleagues point out that rapid growth in global oil consumption has sparked a growing interest in predicting peak oil. Peak oil is the point where oil production reaches a maximum and then declines. Scientists have developed several models to forecast this point, and some put the date at 2020 or later. One of the most famous forecast models is called the Hubbert model2. It assumes that global oil production will follow a bell shaped curve3. A related concept is that4 of Peak Oil. The term Peak Oil indicates the moment in which world wide production will peak, afterwards to start on irreversible decline. The Hubbert model accurately predicted that oil production would peak in the United States in1970. The model has since gained in popularity and has been used to forecast oil production worldwide. However, recent studies show that the model is insufficient to account for5 more plex oil production cycles of some countries. Those cycles can be heavily influenced by technology changes, politics, and other factors, the scientists say. The new study describes development of a new version of the Hubbert model that provides a more realistic and accurate oil production forecast. Using the new model, the scientists evaluated the oil production trends of 47 major oilproducing countries, which supply most of the world39。 s conventional crude oil6. They estimated that worldwide conventional crude oil production will peak in 20xx, years earlier than anticipated. The scientists also showed that the world39。 s oil reserves7 are being reduced at a rate of percent a year. The new model could help inform energyrelated decisions and public policy debate, theysuggest. 第三篇 公民科学家 理解大自然对气候变化有怎样的反应需要监视世界各个角落的关键生命周期事件 ——花开、叶子的出现 、 第一只青蛙叫出春天的到来。 但是生态学家不可能去到世界的各个角落 ，所以他们向非科学家求助，这些非科学家有时也被称作公民科学家。 气象科学家不可能足迹遍及天下。 因为在世界上有如此多的地方，没有足够的科学家来观察它们。 所以他们请求你来帮助观察全世界气候变化的迹象。 公民科学家运动鼓励普通人根据自己的兴趣来观察某一个特定的方面 ——鸟儿 、 树木 、 花开等等 ——并把他们的观察结果发送到一个巨大的数据库来供专业科学家研究。 这 有助于数量有限的科学家得到如果只靠他们自己根本收集不到的巨大数据。 就像公民记者帮助报道传统新闻报道方式所忽略的小型社区的相关信息一样 ， 公民科学家也对他们所居住的环境很熟悉。 所需要的就是每天或每周留出几分钟来搜集数据并发送过来。 一群科学家和教育家在去年发起了一个叫做纽约国家物候学的组织。 ”物候学 ”就是科学家们所说的在自然中研究每个事件的时间。 其中一个小组的首要尝试就是依靠科学家和非科学家来收集关于每年植物开花和长叶子的数据。 这一项目叫做花季追踪计划 ， 它收集遍布美国的各种各样的植物生长周期的数据。 参与这一项 目的人们 ——这一计划对所有人开放 ——把他们的观察记录在花季追踪计划网站上。 “人们不需要是植物学家 ——他们仅仅需要环视四周看看周 围有什么。 ”Jennifer Schwartz新东方在线 [ ] 20xx 职称英语强化班网络课堂电子教材系列 阅读理解中文朗读 6 说 ， 她 是这项计划的教育顾问。 ”通过收集数据 ， 我们就能够估算出气候变化对植物和生物群落会有怎样的影响。 ” Citizen Scientists Understanding how nature responds to climate change will require monitoring ke。
