1 .With speed increasingly seen as the key to competitive advantage, the dream is to marry the control of an established company with the responsiveness of a start-up. As Linda Applegate reports, advances in IT now means that the “big small”company is finally feasible.In the hierarchical companies of the 1960s and 1970s, informaiton moved slowly and channels of communication were limited. Over the past few years, however, large companies have come under ever-increasing pressure to collect, process and distribute information more quickly in order to compete with smaller, more nimble rivals. The key challenge facing any sizeable organisation today is how to achieve responsiveness without losing the control inherent in a hierarchical structure.All types of organisation are controlled through two sets of processes. Operating processes define how a company produces, sells, distributes and supports its products and services. Management processes define how a company directs, coordinates and controls these operations. Typical management processes include planning, budgeting and human resource management.Traditional hierarchical organisiations control operating processes through standardisations of jobs. These jobs are separated into sequential steps and carried out under direct supervision. However, the line workers lack both the authority and motivation to improve these routine tasks and are limited by their local view of the business. Management processes in such companies are also hampered by the time it takes to recognise that change is needed. Thus, hierarchical control is only truly effective in relatively stable business environments where change happens slowly.Entrepreneurial organisations, on the other hand, allow fast response without any loss of control. Daily personal interaction between the owner and employees ensures flexibility and responsiveness, while instant feedback ensures effective control. However, as the company becomes larger and more complex, this control breaks down and more structured operating and management processes required.Information age organisations can manage the complexity of the large hierarchical structure without losing the speed of the entrepreneurial start-up. IT plays a critical role. It coordinates complex fast-cycle operating processes and, more importantly, gives decision-makers quick access to detailed, real-time information about operations and market performance. Once all the information is flowing, employees can quickly evaluate their decisions and continually refine both strategy and operations. Organisational control then becomes a dynamic, information-enabled learning process rather than a static monitoring system.However, although IT makes the “big small” company possible, it can not motivate people to use information in order to act on behalf of the organisation. The challenge for organisation is therefore to ensure that managers and employees share the same perspective on the business and are motivated to accomplish the same goals。

第三单元动植物课文A植物的适应性同人类和动物一样，植物必须适应周围的环境以求生存。

生存，通常即意味着竞争。

植物也需要竞争吗？这一点或许令人费解，但事实往往就是这样。

首先，一棵植物必须同其他植物竞争阳光、空气、土壤以及水分。

其次，它还要应对人类和动物的威胁，因为人和动物会把它吃掉或者使得环境难以适合植物的生长。

再者，环境本身可能对植物生长不利或者难以满足植物生长的需要：有没有足够的阳光、水分、空气以及土壤? 对于某一植物种类来说，气候是否足够温暖或凉爽？对于植物，尤其是绿色植物，光照是极其重要的。

绿色植物在光照条件下制造营养，这一过程叫做光合作用。

光照还能够影响水分的吸收率和花粉的形成率。

温度也是必须考虑的因素。

在零下1摄氏度或零上43摄氏度条件下，大多数植物会受到严重伤害甚至死亡。

温度能够直接影响种子的形成以及花蕾的产生，同时还决定着植被的地理分布。

没有水，植物将无法生存。

许多植物在生长过程中需要大量的水分。

因此，对于植物来说，环境的湿度和降水量、溪流湖泊的存在与否以及土壤的湿度都是非常重要的。

大多数植物需要大量的空气。

大气中包含了对它们的生存极其重要的气体：氧气、二氧化碳、水蒸气和氮气。

除了空气本身以外，由于空气的运动而形成的风也极大地影响着植物。

风能够传播花粉、孢子以及某些种子，使得植物在许多地方生长。

但是强风可能会毁坏甚至杀死植被，尤其是树木。

它也可能吹走植被需要的土壤。

同时，风还会加速水分的蒸发，导致水分不足。

土壤对于陆地植被来说是极其重要的。

植物的生长很大程度上取决于土壤的性质：它的湿度、酸度、矿物质，以及含氧量。

植物还受到周围其它生物的影响。

它必须抵挡寄生虫、饥饿的鸟类、食草动物或啮齿动物的侵袭。

而植物又需要动物来传播花粉或者散播种子。

我们从树木和灌木的枝叶能看到植物适应环境以最大限度地获取阳光和空气的特征。

在山毛榉、榆树、橡树、果树及栗树等树种中，可以看到有些新枝是垂直生长的，而有些则是水平生长的。

是什么让我们找了这么久?直到1998年，天文学家们才发现我们所说的暗能量，它几乎是宇宙能量的四分之三，在此之前一直被我们所忽视。暗能量是一种未知的能量形式，围绕在我们每个人的周围，轻轻地推拉我们，掌控宇宙的命运。但是，我们对它却几乎一无所知。确实，一些研究人员此前曾预测存在这类能量，但是他们还是会告诉你，探测暗能量是宇宙学在20世纪最具革命性的发现。暗能量可能不仅是构成宇宙的主体，而且，如果能经受住时间的检验，它将需要提出新的物理理论来支撑。
As astronomers have explored this new phenomenon, they have found that, in addition to determining the overall expansion rate of the universe, dark energy has long-term consequences for smaller scales. As you zoom in from the entire observable universe, the first thing you notice is that matter on cosmic scales is distributed in a cobweblike pattern--a filigree of filaments, several tens of millions of light-years long, interspersed with voids of similar size. Simulations show that both matter and dark energy are needed to explain the pattern.
According to models, dark matter began to clump immediately after the big bang, forming spherical blobs that astronomers refer to as "halos." The baryons, in contrast, were initially kept from clumping by their interactions with one another and with radiation. They remained in a hot, gaseous phase. As the universe expanded, this gas cooled and the baryons were able to pack themselves together. The first stars and galaxies coalesced out of this cooled gas a few hundred million years after the big bang. They did not materialize in random locations but in the centers of the dark matter halos that had already taken shape.

Unit 3当所以人的朋友，是私人的事情吗脸谱网有一个重要的隐私人员，但是我怀疑他将从现在存在10年。

那不是因为脸谱不顾一切去掉隐私保护，但由于脸谱和其他社交网站的普及促进了共享个人的一切事物，消除了从公共分离出私事的结点。

由于共享的个人信息的范围扩展到，几个朋友一起归入脸谱的许多杂项的个人的“朋友”标签中，披露的事情成为很常态和私人的事情变得古怪和不合时宜。

脸谱的年轻成员，是那些高中生或者大学生，以及脸谱开始出现在校园里的时候那些舒适共享任何东西分应届毕业生。

它的老成员是仅仅在2006年打开网络工作场所后加入的。

任何人都调整到一个新的善于自我表达超过沉默的价值体系。

脸谱表示它有1.75亿会员，是世界上最大的社会网络。

但在美国，大多数成员都还比较年轻。

脸谱提供广告给5440万成员的目标，且不分年龄人人共享。

但是，如果广告客户想缩小它的目标观众到那些25岁或更老的，数量就会下降到2880万。

它缩小到30或以上岁数的人，脸谱只有仅仅提供2030万。

许多超过30 岁的人尚未注册，因此脸谱有一个惊人的增长机会。

每个星期，新成员是在美国以百万和全球范围会员和个人网络的增长，似乎不受公司在其短暂的五年历史的失态的影响。

其中的一个实例是在二月，当它与它的服务条款拨弄时。

新的语言似乎断言脸谱“不可撤销”的权利是去保留和使用一个成员的个人信息。

即使成员已经关闭了他或她的脸谱帐户，也应该多一点编辑。

这个强烈抗议是大声的，仅仅一些成员需要增加他们的声音去创建一个喧嚣声，然后脸谱恢复旧的语言。

几天后，它为公司和另一项权利和责任的草案，提供了一个草案原则，对将被批准的成员。

脸谱提供给成员很多隐私选项。

脸谱的默认设置是为在某些方面的新的帐户保护用户。

例如，在一个人的个人资料只限于朋友和其他人的学校，工作场所或地理网络。

Unlocking the Climate Puzzle解开气候之谜(1)Life has prospered on this planet for nearly four billion years. In that time, climate had fluctuated drastically, from ice ages lasting tens of thousands of years to epochs of steamy heat. With each change, sundry species have benefited and flourished.Others adapted, faltered, or died. Now, many experts believe, humans are imperiling their own ecological niche with the threat of global warming. The vaporous by-products of civilization, in the form of greenhouse gases such as carbon dioxide (C0₂), have trapped enough heat in the atmosphere to raise Earth's average surface air temperature a half degree Celsius (one degree Fahrenheit) during this century. If the trend continues, it could alter climate patterns worldwide-thawing glaciers, boosting sea level, scorching plains into deserts, and shifting vegetation zones.（1）生命在这个星球上已经发展了近四十亿年。

• 目前，中国的宽带接入技术主要有四种。一是有线电话的同轴电缆光纤混合网技术，二是利用传统电话线不对称数字用户环路技术，三是小区以太技术，四是直接卫星连接技术。
• 例如： • 例1. The testing of machines by this method
entails some loss of power.
• 译文∶用这种方法测试机器会浪费一定的能量。
• 例2. Today the electronic computer is widely used in solving mathematical problems having to do with weather forecasting and putting satellites into orbit.
• 译文：对小于米的单位，十进制是这样应用的：米被分成分米（dm）、厘米（cm）、毫米（mm)等等，使测量变得非常简单。此外， 1000米合成一公里（km），作为用来测量长距离的单位。
• 以上篇章中共出现了四个句子，其中前三个句子采用了被动语态（算上第三句中的which引导的非限定性定于从句）。在翻译成汉语时需要作必要的调整，一般情况下要用主动语态结ቤተ መጻሕፍቲ ባይዱ进行翻译。该译文如下：
The explosion of the device’s three 30-kiloton atomic mechanism went smoothly.
It was the largest nuclear blast so far in the Atomic Energy Commission project to stimulate massive stores of natural gas locked in rock formations.
