学术英语课文翻译Unit1人们如何做出决策理性的人认为在保证金1.经济学家通常假设人是理性的。

理性的人们系统地,有目的地做最好的,他们可以实现他们的目标,考虑到可用的机会。

当你学习经济学,你会遇到公司决定雇佣多少工人,有多少他们的产品生产和销售利润最大化。

你也会遇到那些决定花多少时间工作和买什么商品和服务产生的收入来实现最高水平的满意度。

2.理性的人知道生活中的决策很少是黑白的，但通常是灰色的。

在吃饭的时候，你面对的不是空腹或是像猪一样进食，而是吃额外的一匙土豆泥。

当考试开始时，你的决定不是介于两者之间，而是让他们减少或学习一天24小时，而不是花更多的时间复习笔记而不是看电视。

经济学家用“边际变化”这个术语来描述对现有的行动计划的调整。

请记住，边际意味着“边缘如此边缘的变化是在你正在做的边缘周围的调整”。

理性的人往往通过比较边际收益和边际成本来做出决定。

3.例如，考虑一家航空公司决定向待机乘客收取多少费用。

假设撒德躺在横跨美国的200座飞机上，航空公司损失100,000英镑。

在这种情况下，每个座位的平均成本是1,000美元/ 200美元，这是500美元。

有人可能会得出这样的结论：航空公司不应该售出票价低于500美元的机票。

事实上，一家理性的航空公司通常可以通过考虑利润率来提高利润。

想象一下，一架飞机即将起飞，有10个空座位，候机旅客在门口等候，将支付300美元的座位。

航空公司应该把票卖掉吗？当然应该。

如果飞机有空座位，增加一个乘客的成本很小。

乘飞机的平均成本是S500，边际成本仅仅是额外的乘客将消耗的花生袋和苏打水的成本。

只要备用乘客支付超过边际成本，售票是有利可图的。

4.边际决策有助于解释一些令人费解的经济现象。

这里有一个经典的问题：为什么水这么便宜，而钻石这么贵？人类需要水来生存，而钻石是不必要的；但出于某种原因，人们愿意付出更多的钻石比一杯水。

原因是一个人愿意支付任何好处是基于一个额外单位的好处会产生边际效益。

学术英语(社科)Unit3三单元原文及翻译

UNIT 3 Unemployment1. Losing a job can be the most distressing economic event in a person’s life. Most people rely on their labor earnings to maintain their standard of living, and many people get from their work not only income but also a sense of personal accomplishment.A job loss means a lower living standard in the present, anxiety about the future, and reducedself-esteem. It is not surprising, therefore, that politicians campaigning for office often speak about how their proposed policies will help create jobs.失去一份工作可能是最痛苦的经济事件在一个人的生活。

大多数人们依靠自己的劳动收入来维持他们的生活标准,许多人会从他们的工作得到的不仅是收入，还有自己的成就感。

一个失去工作意味着现在要定一个更低的生活标准,焦虑未来,并丧失自尊心。

这并不奇怪,因此,政治家竞选办公室经常谈论他们所提出的政策将帮助创造就业机会。

4.In judging how serious the problem of unemployment is, one question to consider is whether unemployment is typically a short-term or long-term condition. If unemployment is short-term, one might conclude that it is not a big problem. Workers may require a few weeks between jobs to find the openings that best suit their tastes and skills. Yet if unemployment is long-term, one might conclude that it is a serious problem. Workers unemployed for many months are more likely to suffer economic and psychological hardship.判断失业问题有多么严重时，其中一个问题就是要考虑是否失业通常是一个短期或长期的条件。

For example, the categories of classificationshould be mutually exclusive and no overlapping is allowed. Reading 1 Causes for Global Warming2. Coal is the most abundant fossil fuel resource. It provides aboutone-quarter of the total energy the world uses, and 40 percent of the electricity generated worldwide is powered by coal. The steel industry also is greatly dependent upon this fossil fuel. Like other depleting sources of global energy, coal reserves are also on a steep decline. Moreover, coal is a greenhouse gas nightmare.Natural gas is comprised mostly of methane, although it also contains ethane, propane and butane. It is a convenient and efficient energy source. The major consumers of natural gas are the residential, commercial and industrial sectors. It is also used to generate electricity. Unlike other fossil fuels, natural gas is cleaner and causes less pollution. Like other fossil fuels, this resource is depleting rapidly.Task 2 Understanding Lectures through ClassificationListening 11.

What’s more, there is a health factor that affects both of them.Canned food loses some of the original fresh food nutrients when stored, and also has to be tinned with many preservatives and chemical factors that prolong the shelf life and apparent freshness of the food but could become toxic if consumed too often. Fresh food, on the other hand, often comes straight from a farm and has all the nutrients Mother Nature intended for it. As we can see, fresh food offers many benefits that canned food lacks. Therefore, an informed diner should always choose to eat fresh. After all, we could all use to improve our health.Task 2 Understanding Lectures Through Comparison and ContrastListening 12. 1) T.

So what we are doing right now with computers with theenergy consumed by 1,200 houses, the brain is doing with the energy consumed by your laptop.5) F. How does that compare with the way computers work? Inthe computer, you have all the data going through the central processing unit, and any piece of data basically has to go through that bottleneck, whereas in the brain, what you have is these neurons.6) T. This is something that we’ve been working on for the last couple of years.3. 120,000 processors10 to the 16 bits per second1.5 megawatts10 quadrillion bits per second10 watts4. Although computers have strong power to process data, they stillcannot compare to the brain of human beings in which an unbelievable number of neurons connect and react with each other so that a real net could be accomplished perfectly.

Classification is made on the basis of a clear definition.5) In order to make a clear and logic classification, one needs to follow a principle ofclassification and go on with a system consistently. For example, the categories of classification should be mutually exclusive and no overlapping is allowed.Reading 1 Causes for Global Warming2. Coal is the most abundant fossil fuel resource. It provides about one-quarter of the totalenergy the world uses, and 40 percent of the electricity generated worldwide is powered by coal. The steel industry also is greatly dependent upon this fossil fuel. Like other depletingsources of global energy, coal reserves are also on a steep decline. Moreover, coal is a greenhouse gas nightmare. Natural gas is comprised mostly of methane, although it also contains ethane, propane and butane. It is a convenient and efficient energy source. The major consumers of natural gas are the residential, commercial and industrial sectors. It is also used to generate electricity. Unlike other fossil fuels, natural gas is cleaner and causes less pollution. Like other fossil fuels, this resource is depleting rapidly.Task 2 Understanding Lectures through ClassificationListening 11.

Id functions on “the Pleasure Principle”, while ego works on “the Reality Principle” and superego is the internalized rules of a society. Ego is in between id and superego.Task 3 Reading Classification ArticlesReading 2 Renewable Energy Sources—A Brief Summary1. 1) Renewable energy is energy which comes from natural resources such as

Fresh food, on the other hand, often comes straight froma farm and has all the nutrients Mother Nature intended for it. As we can see, fresh foodoffers many benefits that canned food lacks. Therefore, an informed diner should always choose to eat fresh. After all, we could all use to improve our health.Task 2 Understanding Lectures Through Comparison and ContrastListening 12. 1) T.
