一、Passage A Translation 无名英雄：职业父亲意味着什么？ 在我们的孪生女儿出生后的第一次“约会”时，我和丈夫一起去看了一部名为《玩具总动员》的电影。我们很喜欢这部片子，但随后我丈夫问道：“父亲在哪儿呢？”起初我还认为因为一个小小的失误而批评一部很吸引人的家庭影片似乎是太偏狭了。可后来越想越觉得这一疏忽太严重了。父亲不仅没有出现，他甚至没有被提到——尽管家中有婴儿，说明父亲不可能离开太长时间。影片给人的感觉是，父亲出现与否似乎是个极次要的细节，甚至不需要做任何解释。 新闻媒体倾向于把父亲边缘化，这只是一个例子，它反映了在美国发生的巨大的社会变化。大卫·布兰肯霍恩在《无父之国》一书中将这种倾向称之为“无需父亲”观念。 职业母亲（我想这应是与无职业母亲相对而言的）奋斗的故事从媒体上无尽无休地轰击着我们。与此同时，媒体上绝大多数与父亲有关的故事又集中表现暴力的丈夫或没出息的父亲形象。看起来似乎父亲唯一值得人们提及的是因为他们做家务太少而受到指责的时候（我怀疑这一说法的可靠性，因为“家务”的定义中很少包括打扫屋顶的雨水沟，给汽车换机油或其他一些典型的由男人们做的事），或者是在他们去世的时候。当布兰肯霍恩先生就“顾家的好男人”一词的词义对父亲们进行调查时，许多父亲都回答，这一词语只有在葬礼上听到过。 这种“无需父亲”综合征的一个例外是家庭全职父亲所受到的媒体的赞扬。我并非暗指这些家庭全职父亲作出的承诺不值得人们的支持，我只是想指出正在实际生效的双重标准：家庭全职父亲受到人们的赞扬，而家庭全职母亲和养家糊口的父亲，所得到文化上的认同却很少，甚至完全得不到。 我们用来讨论父亲的角色（即没出息的父亲）的话语本身就显示出人们对大多数男人默默无闻而自豪地履行对家庭的责任缺乏赏识。我们几乎从来没听到“职业父亲”这一说法，在人们呼吁应该给予工作者在工作地点上更大的灵活性时，很少有人认为这种呼吁不但适用于女性，同样也适应于男性。我们这个社会表现出的是，似乎家庭职责对父亲来说并不像对母亲那么重要——似乎事业上的满足就是男人生活的全部。 更让人感到侮辱的是最近媒体的这种倾向，即把家庭主妇看成是一种“地位的象征”——就像一辆名贵的汽车，据说只有少数男人才享受得起这种奢侈与豪华。这暗示家里有家庭主妇的男人比那些妻子在外工作的男人日子过得更舒适，因为他们拥有全职管家这种“奢侈品”。然而，实际上作为家庭唯一挣钱者的男人要承受很多压力。当他们的那份工作是家庭收入的唯一来源的时候，失业，或者甚至只不过是受到失业的威胁，对他们而言也构成了巨大的困难。同样，家庭唯一的工资收入者在想辞去不太满意的工作时，其灵活程度也要小一些，因为这种工作变换会使他们失去收入。此外，为了给家庭挣更多的钱，许多丈夫超时工作或兼做第二职业。对于这些男人来说，正是这份工作所支撑的家庭，使他们觉得值得付出。

Unit 1 无名英雄：职业父亲意味着什么？ 在我们的孪生女儿出生后的第一次“约会”时，我和丈夫一起去看了一部名为《玩具总动员》的电影。我们很喜欢这部片子，但随后我丈夫问道：“父亲在哪儿呢？”起初我还认为因为一个小小的失误而批评一部很吸引人的家庭影片似乎是太偏狭了。可后来越想越觉得这一疏忽太严重了。父亲不仅没有出现，他甚至没有被提到——尽管家中有婴儿，说明他不可能离开太长时间。影片给人的感觉是，父亲出现与否似乎是个极次要的细节，甚至不需要做任何解释。新闻媒体倾向于把父亲的边缘化，这只是一个例子，它反映了在美国发生的巨大的社会变化。大卫?布兰肯霍恩在《无父之国》一书中将这种倾向称之为“无需父亲”观念。 职业母亲（我想这应是与无职业母亲相对而言的）奋斗的故事从媒体上无尽无休地轰击着我们。与此同时，媒体上绝大多数有关父亲的故事又集中表现暴力的丈夫或没出息的父亲。看起来似乎父亲惟一值得人们提及的时候是因为他们做家务太少而受到指责的时候（我怀疑这一说法的可靠性，因为“家务”的定义中很少包括打扫屋顶的雨水沟、给汽车换机油或其它一些典型地由男人们做的事），或者是在他们去世的时候。当布兰肯霍恩先生就“顾家的好男人”一词的词义对父亲们进行调查时，许多父亲都回答这一词语只有在葬礼上听到。 这种“无需父亲”综合症的一个例外是家庭全职父亲所受到的媒体的赞扬。我并非暗指这些家庭全职父亲作出的承诺不值得人们的支持，我只是想指出在实际生效的双重标准：家庭全职父亲受到人们的赞扬，而家庭全职母亲和养家活口的父亲，所得到文化上的认同却很少，甚至完全得不到。 我们用来讨论父亲角色（即没出息的父亲）的话语本身就显示出人们对大多数男人默默无闻而自豪地履行对家庭承担的责任缺乏赏识。我们几乎从来没听到“职业父亲”这一说法，在人们呼吁应该考虑给予工作者在工作地点上更大的灵活性时，很少有人认为这种呼吁不但适用于女子，同样也适应于男子。我们这个社会表现出似乎家庭职责对父亲来说并不象对母亲那么重要——似乎事业上的满足就是男人生活的全部。 更让人感到侮辱的是最近媒体的这种倾向，即把家庭主妇看成是一种“地位的象征” ——就像一辆名贵的汽车，只有据说少数男人才享受得起这种奢侈与豪华。这暗示家里有家庭主妇的男人比那些妻子在外工作的男人日子过得更舒适，因为他们拥有全职管家这种“奢侈品”。然而，实际上作为家庭惟一挣钱者的男人要承受很多压力。当他们的那份工作是家庭收入的惟一来源的时候，失业，或者甚至只不过是受到失业的威胁，对他们来说显然构成更大的困难。同样，家庭惟一的工资收入者在想辞去不太满意的工作时，其灵活程度也要小一些，因为这种工作变换会使他们失去收入。此外，为了给家庭挣更多的钱，许多丈夫超时工作或兼做第二职业。对于这些男人来说，正是这份工作所支撑的家庭，使得他们值得付出努力。很多男人相信母亲呆在家里对小孩十分重要，这种信念使得他们乐意地担起家里惟一挣钱人的担子。 目前，研究者们普遍认为家庭中没有父亲会对小孩——因此对整个社会——带来严重的问题。然而，我们这个社会并没有把“普通”父亲作为正面角色为未来的父亲树立榜样，相反地，却常常持放弃态度，认为传统的父道从最好的方面说是已经过时，从最坏的方面讲就是危险的反动。这使得许多男人对他们作为父亲的角色的价值提出疑问。 作为一个社会，我们需要认识到对于孩子来说，父亲是与母亲同等重要的，不仅仅在经济支持上，而且在感情依靠、教育和纪律训导方面都是如此。我们仅仅意识到没有父亲是一个问题是不够的，也不能只是站在坟墓旁边哀悼“顾家好男人”的去世，随后又找一个人来替代他（请问一问已失去父亲的人，这是否可能）。我们必须承认我们是如何贬低了父道的价值，我们必须努力向男人们显示，他们在孩子们的生活中是多么不可缺少，多么重要。

Lesson2 Exercises 1. Put the following into Chinese. （1）Ohm’s law states that the voltage across a resistor is directly proportional to the current flowing through the resistor. The constant of proportionality is the resistance value of the resistor in ohms. 流过电路里电阻的电流，与加在电阻两端的电压成正比，与电阻的阻值成反比。这就是欧姆定律。 （2）Many materials, however, closely approximate an ideal linear resistor over a desired operating region. 不过，许多材料在规定的工作范围内非常接近理想线性电阻。 （3）It should be noted that an ideal voltage source (dependent or independent ) will produce any current required to ensure that the terminal voltage is as stated, whereas an ideal current source will produce the necessary voltage to ensure the stated current flow. 应该注意：一个理想电压源（独立或受控）可向电路提供任意电流以保证其端电压为规定值，而电流源可向电路提供任意电压以保证其规定电流。 （4）A different class of relationship occurs because of the restriction that some specific type of network element places on the variables. Still another class of relationship is one between several variable of the same type which occurs as the result of the network configuration, i. e., the manner in which the various element of the network are interconnected. 一种不同类型的关系是由于网络元件的某种特定类型的连接对变量的约束。另一类关系由于网络结构，即网络的不同元件互相连接的方式所产生的相同形式的一些变量间的关系。 （5）The thermal conductivity of metals is as much as several hundred times that of glass. 金属的导热率比玻璃高几百倍。 （6）Magnetic line of force will，whenever passible, travel through iron or other magnetic materials. 磁力线只要有可能就会通过铁或其它磁性材料。 （7）Actually, 0 o C is indeed the lower limit to temperatures capable of being attained. 事实上绝对零度确是所能达到的温度的最低限度。 2. Translate the following into English. （1）电路元件吸收或释放的功率为元件两端的电压与流过该元件电流的乘积。 The power absorbed or supplied by a circuit element is the product of the voltage across the element and the current through it. （2）理想独立电源是一个有源元件，它所提供的电压或电流不依赖于电路中其他变量。 An ideal independent source is an active element that provides a specified voltage or current that is completely independent of other circuit variables. （3）受控电源是一个有源元件，它所提供的电压或电流受电路中某部分电压或电流控制。 An ideal dependent (or controlled) source is an active element in which the source quantity is controlled by another voltage or current. （4）叠加定理为：线性电路中，任一电压或电流都是电路中各个独立电源单独作用时，在该处产生的电压或电流的叠加。 The superposition principle states that the voltage across (or current through) an element in a linear circuit is the algebraic sum of the voltages across (or current through) that element due to each independent source acting alone. （5）计算机可分为模拟计算机和数字计算机两种。Computers may be classfied as analog and digital．（6）新型晶体管的开关时间缩短了三分之二。The switching time of the new-type transistor is shortened three times． （7）超导体在电气应用上的重要性不能被估计过高。The importance of superconductor in the uses of electricity cannot be overestimated.
