21世纪大学英语4课后习题翻译及答案

全新版21世纪大学英语综合教程4(第三版)课后翻译-CAL-FENGHAI.-(YICAI)-Company One1Unit 1这是西雅图海边阳光明媚、赤日炎炎的一天，穿越海湾能一眼望见远处的岛屿，其自然美景没有受到任何破坏。

人们躺在一片草坪上看书或和恋人相依，一阵充满活力的无伴奏的歌声从草坪的另一端传了过来。

原来是一家咖啡馆外面有4位男子正在唱着一首关于丘比特的情歌，每个人都有着不同的音域。

围了几圈的人群正摇摆着身体合着节奏拍手。

这家咖啡馆的星巴克徽标让我觉得有一点过时，直到有人提到这是世界上第一家开张的星巴克时我才恍然大悟。

我是因为最近的一次调查来到西雅图的。

这项调查是由位于伦敦的经济运转情况中心发起的，旨在了解在世界不同的地方发财致富究竟有多么容易或多么困难——如果不是发财致富，至少也是摆脱贫困。

Unit 2美国满足了我学业深造和职场历练的雄心。

我来的时候差不多是高中学历，而10年后，我拥有了研究生学位，也有了比较成功的职业生涯。

然而，前进的每一步都是通过令人精疲力竭的奋斗取得的。

我的大学学费一部分是通过打多份报酬极低的零工挣来的。

毕业以后，我很幸运地找到一份工作。

可是，适应企业文化需要付出另一种代价。

最初，我需要付出双倍的努力才跟得上。

渐渐地，我意识到如果缺乏自信，别人就不把你当回事儿，于是便学着装出一副自信满满的样子。

迫于裁员潮的威慑，我利用业余时间读了研究生，因为那是我所知道的能在保障工作方面取得优势的唯一办法。

当我有资格申请公民身份时，又花了一大笔律师费，并且忍受了充满压力的数年时光，努力应对种种纷繁复杂的情况以获得在美的永久居住权。

Unit 4我想，令人目眩神速的初恋也许会融入血液中，但经得起考验的爱则永驻心头。

从这个意义上说，爱比躯体更具活力。

爱使我们变得完整，赋予我们平安度过一生所需的一切。

我可以就这样数个小时一直端详着我的妻子。

海浪不断迸溅开来，冲击着她光光的脚丫。

这个世界有时因为伤害和痛苦而大煞风景，我却深深地感恩升起的旭日为我照亮了这样的真爱。

1.由于一次裁员行动和一次重大的银行合并，我一贯有条不紊的生活变得充满了变化。

As a result of a downsizing initiative and a major bank merger, my usually well-ordered life became fraught with changes.2.尽管我生性沉默寡言，但我充分利用了课堂上做口头陈述的机会，这使我不久就信心倍增。

Although I am a rather reticent individual by nature, I made the most of the oral presentations in class. And soon my confidence level soared.3.这位年轻人放弃了稳定的未来，跳出自己的舒适圈，重返激烈的竞争，这使他的亲友们都惊叹不已。

Much to the amazement of his friends and relatives, the young man gave up his secure future, stepped out his comfort zone and rejoined the “rat race.”4.无论在我们的人生道路上遇到什么坎坷，拥有积极的态度才能为未来打开空间。

No matter what life throws our way, having a positive attitude makes room for the future. 5.当然，事业有成是我渴望实现的一个个人目标，但为了物质的东西和个人的荣誉而工作却从来不是我最优先考虑的东西。

Of course, having a fulfilling career is a personal goal I long to achieve. However, working towards materialistic things and personal glorification has never been my first priority.6.失去了工作以后，他重回大学，并最终获得了一份毕业证书。

课内阅读参考译文及课后习题答案(Book 4)Unit 1享受幽默—什么东西令人开怀？1 听了一个有趣的故事会发笑、很开心，古今中外都一样。

这一现象或许同语言本身一样悠久。

那么，到底是什么东西会使一个故事或笑话让人感到滑稽可笑的呢？2 我是第一次辨识出幽默便喜欢上它的人，因此我曾试图跟学生议论和探讨幽默。

这些学生文化差异很大，有来自拉丁美洲的，也有来自中国的。

我还认真地思考过一些滑稽有趣的故事。

这么做完全是出于自己的喜好。

3 为什么听我讲完一个笑话后，班上有些学生会笑得前仰后合，而其他学生看上去就像刚听我读了天气预报一样呢？显然，有些人对幽默比别人更敏感。

而且，我们也发现有的人很善于讲笑话，而有的人要想说一点有趣的事却要费好大的劲。

我们都听人说过这样的话：“我喜欢笑话，但我讲不好，也总是记不住。

”有些人比别人更有幽默感，就像有些人更具有音乐、数学之类的才能一样。

一个真正风趣的人在任何场合都有笑话可讲，而且讲了一个笑话，就会从他记忆里引出一连串的笑话。

一个缺乏幽默感的人不可能成为一群人中最受欢迎的人。

一个真正有幽默感的人不仅受人喜爱，而且在任何聚会上也往往是人们注意的焦点。

这么说是有道理的。

4 甚至有些动物也具有幽默感。

我岳母从前经常来我们家，并能住上很长一段时间。

通常她不喜欢狗，但却很喜欢布利茨恩—我们养过的一条拉布拉多母猎犬。

而且，她们的这种喜欢是相互的。

布利茨恩在很小的时候就常常戏弄外祖母，当外祖母坐在起居室里她最喜欢的那张舒适的椅子上时，布利茨恩就故意把她卧室里的一只拖鞋叼到起居室，并在外祖母刚好够不到的地方蹦来跳去，一直逗到外祖母忍不住站起来去拿那只拖鞋。

外祖母从椅子上一起来，布利茨恩就迅速跳上那椅子，从它那闪亮的棕色眼睛里掠过一丝拉布拉多式的微笑，无疑是在说：“啊哈，你又上了我的当。

”5 典型的笑话或幽默故事由明显的三部分构成。

第一部分是铺垫（即背景），接下来是主干部分（即故事情节），随后便是妙语（即一个出人意料或令人惊讶的结尾）。
