大学英语自学教程上册课后习题答案Unit11-14

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。

他们需要数百小时的学习与练习，即使这样也不能保证每个成年语言学习者都能学好。

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。

你是什么样的语言学习者?如果你是一位成功的语言学习者，那么你大概一直在独立地、主动地、目的明确地学习。

DictationBaseball is America's national sport, played mainly by men. It developed in the mid 19th century from the British games of rounders and cricket. Baseball is also popular in Japan and several Latin American countries, and has been an Olympic sport since in 1972. Softball is similar but uses a large, softer ball and is popular with women. Many Americans play baseball for fun because players do not have to be strong like football players or tall like basketball players. Some people think baseball is too slow, but the team managers often change their players and plans during the game, and there are many exciting plays. Many American families enjoygoing to a Sunday afternoon double-header, that is, two games between the same two teams in one day.翻译你能想像一个身体严重残疾的妇女独自经营一个网站并且像一个专业的体育记者一样详细报道洛杉矶道奇队吗?如果我没有亲眼见到她蜷曲在轮椅里，用固定在头上的一根棍子敲击字键打出她的评论，我是绝不会相信的。

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。

大学英语自学教程上册课文翻译第一课 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。

他们需要数百小时的学习与练习,即使这样也不能保证每个成年语言学习者都能学好。

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。

你是什么样的语言学习者如果你是一位成功的语言学习者,那么你大概一直在独立地,主动地,目的明确地学习。

大学英语自学教程上册课文翻译注释及习题答案This model paper was revised by LINDA on December 15, 2012.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。

他们需要数百小时的学习与练习，即使这样也不能保证每个成年语言学习者都能学好。

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。

Guldbergdecided[07:21.91]一位挪威生物学家古尔伯格[07:25.00]that this problem of circular movementwas worth investigating.[07:28.26]认为这种转圈运动问题值得研究．[07:31.53]He collected many true stories on the subject.[07:34.16]就此课题了收集了许多真实的故事．[07:36.80]One of his stories is about people rowing on a lake [07:39.44]其中一个故事是讲在一个有雾的黑漆漆的夜里，[07:42.08]during a fog on a dark night.[07:44.05]一群人在湖上划船．[07:46.02]One group of rowers who tried to cross three miles of water[07:49.05]这群划船的人想穿过3英里的水面[07:52.08]in foggy weathernever succeeded in reaching their goal. [07:54.62]却怎么也达不到他们的目标.[07:57.15]Without knowing it,they rowed in two large circles.[08:00.48]他们不知不觉地划了两个大圆圈.[08:03.81]When they finally got to the shore,[08:06.14]当他们终于靠岸时,[08:08.46]they discovered that they were at the spot they had started from.[08:11.19]发现又回到了出发的地方.[08:13.92]After studying many stories such as this,[08:16.74]研究了许多这样的故事以后,[08:19.57]Professor Guldberg wrote an article in which he discussed[08:22.54]古尔伯格教授撰文讨论了[08:25.52]Circular Motion as the Basic Motion of Animals.[08:28.30]"转圈运动是动物的基本运动方式".[08:31.09]"A simple example will help you to understand his explanation ofwhy we walk in circles.[08:35.02]一个简单的例子可以帮助你理解他对为什么我们走路会转圈这个问题做的解释.[08:38.95]Have you ever wound up a toy automobile10 and started it off across the floor?[08:42.42]你曾经给一辆玩具汽车上满发条并让它们地板上跑过吗?[08:45.90]Then you know that it will rarely travel in a straight path.[08:48.47]那么你就知道它很少能沿一条直线运动.[08:51.04]It will travel, instead, in some kind of are, or curve.[08:54.02]相反,它会跑成一条弧线或一条曲线[08:57.00]If it is to travel in a straight llne,[08:59.02]如果让它跑成直线,[09:01.05]the wheels on both sideshave to be of exactly equal size.[09:04.22]两边的轮子就要完全一样大小.[09:07.40]If they are not,[09:09.07]如果不是,[09:10.74]the little automobile turns toward the sidewith the smaller wheels.[09:13.86]小玩具汽车就会向较小的轮子那边转.[09:16.98]Circular, movement in walking is caused in much the same way.[09:20.16]行走时的转圈现象也是由十分相同的原因引起的.[09:23.33]Us-ally a manwalking will "watch his step" and "look where he is going."[09:27.25]通常一个人走路时会"注意脚下"并"看清方向".[09:31.17]He needs his senses' especially his eyesto get to the point he intends to reach.[09:35.14]他需要运用他的感觉,特别是眼睛,以到达自己要去的地方.[09:39.11]When he cannot use his eyes to guide his steps,[09:41.77]当他不能用眼睛引导脚步时,[09:44.44]he will walk straight only if he takes a stepof the same length with each foot.[09:47.47]只有两脚迈出的步伐完全一样他才能走得笔直.[09:50.50]In most people,however,muscle development is not the same in both legs[09:54.18]然而对于多数人来说,两腿的肌肉发达程度并不一样,[09:57.86]so that it is probable that the steps will be uneven11.[10:00.44]所以走起步来很可能不匀称.[10:03.01]The difference may be so small that no one is aware of it.[10:05.69]这种差异也许很小以至于没有人会注意到它.[10:08.37]But small as his, it can cause circular movement.[10:11.25]但是虽然差异很小,它却能千百万边境转圈移动.[10:14.14]Let us suppose that a man's left foot takes a step 20 inches long[10:17.67]假设一个人左脚每步走20英寸[10:21.19]and that his right foot takes a step 30 inches long.[10:24.08]而右脚每步走30英寸.[10:26.96]Now suppose he takes ten step[10:29.34]现在假设他走了10步[10:31.72]--five with his left footand five with his right.[10:34.40]----左脚5步右脚5步.[10:37.07]His left foot will travel 100 inches.[10:39.56]其左脚将走100英寸.[10:42.04]His right foot will travel 150 inches.[10:44.82]其右脚则走了150英寸.[10:47.60]This sounds impossible. One foot cannot remain 50 inches behind the other[10:51.53]这听起来不太可能.一只脚不可能落后于另一只脚50英寸.[10:55.46]What really happens?At each step the man turns a little bit to the left.[10:59.29]事实会怎样呢?每走一步,这个人就往左偏一点.[11:03.12]Sooner or later he makes a complete circle[11:05.69]迟早他就会走完整的一圈.[11:08.26]The tracks of his feet, however, make two circles, one inside the other[11:12.00]他的足迹,就这样,形成内外两个圈.[11:15.74]His left foot makes the smaller circle because it is taking smaller steps[11:19.00]他的左脚走了内圈,因为左脚步伐较小.[11:22.27]His right foot makes the larger circle because it is taking larger steps[11:25.83]他的右脚走了外圈,因为右脚步伐较大.[11:29.40]This is why a person may walk in an are when he sets out in a straight line.[11:32.88]这就是一个人往前走直线却反而走出弧线来的原因.[11:36.37]The muscles of a man's arms are no more identical than the muscles of his legs [11:40.09]一个人手臂的肌肉和他的两腿的肌肉一样不是完全相同的.[11:43.82]This explains why the rowers who set out to cross the lakeat night rowed in a circle.[11:47.70]这就解释了为什么划船的人在夜间想划过湖面反而却划成圆圈.[11:51.58]By the same rule, a bird's wings do not develop evenly[11:54.81]同样的规则 ,鸟儿的翅膀也发育不均衡,[11:58.05]and so it will fly in circles when blinded.[12:00.48]于是当蒙住鸟儿的眼睛时,它就会转圈飞.[12:02.91]Thus,dear readers,our circular mystery has a very straight answer.[12:06.39]因此,亲爱的读者,我们的圆圈奥秘却有着一个非常直截了当的答案.。
