大学英语自学教程（上册）课后答案及释义UNIT2Unit 2第一部分Text A【课文译文】税、税、还是税美国人常说，人的一生有两件事可以肯定会发生：死亡和税收。

美国人并不垄断死亡市场，但许多人却感到美国以最重的赋税领先于世界。

税指人们为支持政府而缴纳的资金。

在美国通常有三级政府：联邦政府，州政府及市政府，因此就存在三种税。

收入超过几千元的工薪人士必须向联邦政府缴纳一定比率的税金。

这一比率因人而异，取决于各人的工资数。

联邦政府实行累进收入所得税制，也就是说，税率(14%～70%)随个人收入的增加而增加，由于高额税收，人们在4月15日很不愉快，因为这一天是缴纳税款的日子。

第二种税是缴纳给州政府的，这些州包括纽约，加利福尼亚，北达科他以及其他47个州中的任何一个。

一些州的收入所得税的收取办法同联邦政府的相似，当然其税率要低一些。

一些州设有销售税，即对你在该州所购买的任何商品所收的一定比率的税金。

比如，某人想买一包25美分的烟。

如果该州收取8%的销售税，那么买这包烟要花27美分，这一钱数就包括销售税。

一些州利用收入所得税外加销售税的办法来提高税收，各州的税收法规五花八门，令人费解。

第三种税是向市政府缴纳的。

这种税有两种：一种是财产税(拥有房屋的人都必须交税)，另一种是本国消费税，即对城市汽车所征收的税金。

城市将这些资金用于教育、警察和消防部门、公共设施及市政建设。

由于美国人须付高额税金，所以他们经常感到每周有一天纯粹是在为缴税而工作。

人们总是在抱怨税收太高。

他们常常抗议政府滥用他们的税金。

他们说政府将太多的钱花在无用且不符合实际的项目上了。

尽管美国人在很多问题上有不同的看法，但他们在一个话题上的意见总是一致的：税收太高。

【课文难点注释】1．The federal government has a graduated income tax,that is,the percentage of the tax increases as a person's income increases.(Para 3)联邦政府实行累进收入所得税制，也就是说，税率随个人收入的增加而增加。

大学英语自学课程（上）答案Directions: Read the following article about work. Are sentences 1-9 “True” or “False”?下面的短文后列出了9个句子，请根据短文的内容对每个句子做出判断。

Work Is a ServiceYoung people may ask themselves questions like this when they apply for employment: “What are my working hours? What are my extra benefits besides wages? What holidays will I have off? Will I have enough time to hang out with my friends or pursue my hobbies?” With questions like these, h owever, when we focus on our leisure hours instead of our working hours, we may be prevented from seeing a much greater opportunity.Good work attitudes, habits, and skills are learned through successful work experiences. Let me illustrate. On the ranch (牧场) where I grew up, the cows had to be milked before dawn every day. When I was just 10 years old, I would enter our barnyard where there were about 10 to 12 cows waiting for me to let them into the milking barn. My mother and father used to say out loud t o the cows, “Good morning. It’s good to see you!”I have to confess that as a young boy I didn’t feel quite the same way toward the cows.After each cow was milked, I poured the milk from the pail into a 10-gallon can. Each can weighed about 80 pounds when full. It made me stretch my young muscles as I carried them to the road for the dairy to pick up.My father and mother quite frequently helped me with milking the cows. I remember my father and mother continued to milk until they were in their late 80s. B ut Father didn’t milk the cows because he had to; he milked them because theyneeded to be milked. There is a difference. To him, these animals were not just cows—they were Big Blackie and Bossie and Sally and Betsy. He wanted them to be content. He always said that contented cows give good milk. To my father, milking cows—as unsophisticated as it may seem—was not an extra burden; it was an opportunity. Milking was not a job for him; it was a service.This philosophy is something that helped me as I grew up. It helped me to find out that all honest work is honorable. Within a few years I realized that routinely performing these chores actually began to give me a sense of confidence and empowerment. I took pride in my work. We control our own attitudes towards work. Self-confidence and empowerment can serve us well—in the classroom or on Wall Street.Instead of thinking of our daily work as an extra burden, we should think of it as an opportunity. That’s just the way my father taught me to feel about the cows. Those teachings have remained with me all my life, and I continue to visit the ranch and its memories as often as possible.1.

第一部分　Text　A【课文译文】大　西　洋大西洋是将欧洲和美洲分隔开的海洋之一。

它使南北美洲长达几个世纪之久都未被人发现。

人们对大西洋有许多误解，这使得早期的海员不愿意远航驶入大西洋。

一种想法是大西洋远抵“世界的边缘”，海员们担心他们会一直航行到地球边上掉落下去。

另一个想法是在赤道处，大西洋的海水是滚烫的。

大西洋的面积只是太平洋的一半，但也非常辽阔。

哥伦布穿越过的地方宽达4000多英里(6000公里)。

即使最窄的地方宽度也有大约2000英里(3200公里)，这是一片位于南美洲最东端与非洲最西端之间的水域。

大西洋有两点非同寻常。

其一是在如此辽阔的海洋里少有岛屿。

另外，大西洋是世界上含盐量最高的海洋。

大西洋海水量很大，人们无法想像到底有多少水。

但如果假设不再有降雨和河水注入，则需4000年大西洋才会干涸。

大西洋平均水深有2英里(3.2公里)多一点，但有些地方要深得多。

最深处在波多黎各岛附近，深达30246英尺——约6英里(9.6公里)。

世界上最长的山脉之一从大西洋海底隆起，这条山脉沿海底中部向南北延伸，几座山峰露出海面，形成岛屿。

亚速尔群岛就是大西洋中部山脉露出水面的几座山峰。

佛罗里达州向东几百英里有一处海域叫马尾藻海，这里由于很少刮风，海面很平静。

在使用帆船的时代，船员们担心他们会因无风而在此处无法航行。

有时他们确实会遇到这种情况。

海流有时被称作“海洋中的河流”。

大西洋有一条这种“河流”，叫做墨西哥湾流，这是一股暖水流；另外一条是拉布拉多海流——这是来自北冰洋的冷水流。

洋流对流域附近大陆的气候有影响。

大西洋为两岸的人们提供了丰富的食物。

大浅滩是最著名的捕鱼区之一，位于纽芬兰附近。

今天，大西洋是一条重要的航路，这条航路并不总是风平浪静，毫无危险。

暴风雨会掠过洋面，堆起大浪。

从北冰洋漂来的冰山也会横穿航道。

我们现在有快捷的旅行方式，这个大洋似乎也变小了。

哥伦布横越大西洋用了两个多月的时间，一艘现代化快轮不到4天就可完成这一航程，而乘飞机从纽约到伦敦只用8小时，从南美到非洲只用4小时。

Unit 8第一部分 Text A【课文译文】卫星通信在20世纪初，有四种远距离传送信息和接收信息的有效方式：印刷、摄影、电报和电话。

到本世纪中叶，无线电和电视作为传送声音和/或图像的方式已经得到确立。

1964年，首次通过卫星传送了东京奥林匹克运动会的节目。

为了通过卫星传送像奥运会这样的事件，先要把电视信号变成无线电波，然后把无线电波从地面站发射到轨道卫星上。

卫星接收到无线电信号并把信号传送回地球，在地球上另一个站接收电波并把电波变成电视信号。

因为任何形式的声音或视觉信息都能转变成无线电波，所以卫星不仅能传送电视广播，而且也能传递电话以及书、杂志一类的印刷物品的信息。

卫星传送信息，电脑储存信息，电视显示信息，这三者的结合将把每一家变成教育和娱乐中心。

从理论上来说，每个人都可以利用无穷数量的信息。

1974年，美国“空中教师”卫星把教育节目传送到了偏远地区的教室，这说明了通信卫星的另一个重要用途。

1975年，很多印度人看到了电视上的农业和健康节目，这是他们第一次看到电视。

卫星也显示了它如何为生活在闭塞、交通不便的地区的人们提供帮助。

例如，闭塞地区的卫生工作者能把病人伤口的图片传送给远处的医生，然后他就能根据医生的指导来治疗那个病人。

然而，通信卫星最普遍的用途是传送电话。

大部分电话经过40 000英里传送到卫星，然后再回到地球。

10年前，一个卫星能同时接收和传送的电话交谈超过33 000个，而现在仅仅一个卫星就能传送100 000个电话交谈以及数百个电视频道的节目——这些都是同步进行的。

远距离通信能使来自世界各地的信息得到快速、便利的使用，但有些人担心这有可能威胁到我们的隐私。

如果个人的信息储存在电脑里，那么它可能会很容易地通过卫星传送给任何一个付得起服务费的人。

另一个担忧是通信系统会使人们互相隔离。

如果人们能在家里购物，不离开家就能存、取款，在电视上能看到任何一部电影，得到他们所需要的信息，那么人与人之间就不会有那么多的接触。

Unit 1第一部分 Text A【课文译文】怎样成为一名成功的语言学习者“学习一门语言很容易，即使小孩也能做得到。

”大多数正在学习第二语言的成年人会不同意这种说法。

对他们来说，学习一门语言是非常困难的事情。

语言学习不同于其他学习。

许多人很聪明，在自己的领域很成功，但他们发现很难学好一门语言。

相反，一些人学习语言很成功，但却发现很难在其他领域有所成就。

语言教师常常向语言学习者提出建议：“要用新的语言尽量多阅读”，“每天练习说这种语言”，“与说这种语言的人住在一起”，“不要翻译——尽量用这种新的语言去思考”，“要像孩子学语言一样去学习新语言”，“放松地去学习语言。

”然而，成功的语言学习者是怎样做的呢?语言学习研究表明，成功的语言学习者在许多方面都有相似之处。

首先，成功的语言学习者独立学习。

他们不依赖书本和老师，而且能找到自己学习语言的方法。

他们不是等待老师来解释，而是自己尽力去找到语言的句式和规则。

他们寻找线索并由自己得出结论，从而做出正确的猜测。

如果猜错，他们就再猜一遍。

他们都努力从错误中学习。

成功的语言学习是一种主动的学习。

因此，成功的语言学习者不是坐等时机而是主动寻找机会来使用语言。

他们找到(说)这种语言的人进行练习，出错时请这些人纠正。

他们不失时机地进行交流，不怕重复所听到的话，也不怕说出离奇的话，他们不在乎出错，并乐于反复尝试。

当交流困难时，他们可以接受不确切或不完整的信息。

对他们来说，更重要的是学习用这种语言思考，而不是知道每个词的意思。

最后，成功的语言学习者学习目的明确。

他们想学习一门语言是因为他们对这门语言以及说这种语言的人感兴趣。

他们有必要学习这门语言去和那些人交流并向他们学习。

他们发现经常练习使用这种语言很容易，因为他们想利用这种语言来学习。
