新视野大学英语4课后翻译 UNIT 3You are legally entitled to take faulty goods back to the store where you purchased them, but you are supposed to account for why you want to do so. You only need to fill out a form to get your membership, which entitles you to a discount on goods. One year ago, the car dealer tried to drum up buyers by offering good services. Now, his business is thriving. The crime was looked into carefully before he was convicted of murder. I called the Freeway Service Patrol for help after my car broke down on the freeway. Twenty minutes later, they came to my rescue and left a $ 150 receipt. Faced with the threat of losing their jobs, these workers yielded to the management's advice and went back to work . The middle-aged man who took the boy bled the father for $20,000 as a compensation for the loss of his company. The man living on welfare began to set up his own market, one step at a time and his business is thriving. UNIT 4By installing the latest wireless transmission systems, a parade of urban centers and industrial zones from Beijing to Budapest are stepping directly into the Information Age. Widespread access to information technology promises to condense the time required to change from labor-intensive assembly work to industries that involve engineering, marketing and design. Modern communications will give countries like China and Vietnam a huge advantage over countries stuck with old technologies. There is little dispute that communications will be a key factor separating the winners from the losers. The economy of the country is stuck in recession and it barely has the money to scratch the surface of the problem. Businesses eager for reliable service are willing to pay a significantly high price tag for a wireless call. Having an operation there is like having an endless pile of money at your disposal. For countries that have lagged behind for so long, the temptation to move ahead in one jump is hard to resist. UNIT 5Poets and philosophers all speak highly of themselves for seeking out solitude, from which they can draw inspiration. A humble person tends to suffer from solitude, feeling himself inadequate company, longing for others to be around. The widowed old lady was so lonely that she would talk at length to the strangers in the supermarket about her pets. The condition of loneliness rises and falls, but our need to talk goes on forever - the need of telling someone the daily succession of small observations and opinions. To a person living alone, it's important to stay rational and settle down and make himself comfortable, and find some grace and pleasure in his condition. If you live with other people, their temporary absence can be refreshing. Scientific surveys show that those who live alone talk at length to themselves and their pets and the television. It's important to stop waiting and settle down and make ourselves comfortable, at
【山盟海誓】突然想问如果山山和紫紫同时掉水里,你们先救谁? 看了下面的文章之后,我突然想问那些就是山楂又是紫迷的朋友:如果山山和紫紫同时掉水里,你们先救谁?(如果难以回答,可以参考一下下面的文章。。。)女人经常会问:我和你老妈同时掉在了水里先救谁呢让我们来看看古人是怎么做的...孟子:从小死了老爸,老妈拉扯我不容易,为了让我健康成长,又搬了三次的家,给我吃好的穿好的为得就是让我有出息。老妈和老婆落水当然先救老妈了,万恶淫为首,百善孝为先嘛!老婆死了我可以再找一个,老妈死了可不能再找一个,再找一个那就是後妈了。听说後妈没几个好的。「世上只有妈妈好,没妈的孩子像根草。老妈,我来救你了」。扑通一声孟子跳下了水。周幽王:老婆和老妈落水了当然得先救老婆了。想当年俺为了逗亲爱的褒姒笑一笑,连江山都不要了,连自己的小命都不要了,何况是老妈?再说这死老太婆在立太子的时侯老是偏向俺弟弟,害得俺差点都没当成太子。「情深深雨蒙蒙,我对你的爱很深,褒姒我来救你了。」周幽王扑通一声跳进了水里。刘备:兄弟如手足,老婆如衣服,衣服破尚可补,手足断安可续?只要俺二弟和三弟没掉水里就行了,其它人俺可不管他。「老婆,老妈。你们死的好惨呀!」刘备一头栽在河边上嚎嚎大哭起来。曹操:宁叫我负天下人,休叫天下人负我。管它是老婆还是老妈了,只要不是我掉水里就行了。「轻轻的我走了,正如我轻轻的来,我挥一挥手,不带走一片云彩。」曹操哼著诗提著剑慢慢的走远了。屈原:这个世界太黑暗了,这个国家太腐败了,活著也没啥意思,不如都死了乾净,沧浪之水清兮,可以濯吾缨,沧浪之水浊兮,可以濯吾足。投身于河水中倒是一个挺好的归宿。「现在的一片天,是肮脏的一片天,星星在文明的天空里再也看不见老婆,老妈,我和你们一起死」屈原一边唱著一边跳进了水里。庄子:生又何欢,死又何哀?其始而本无生;非徒无生也,而本无形;非徒无形也。老妈和老婆死了就死好了,不过是从有形的元气状态回到了无形的元气状态,有啥好伤心的呢?救他们干啥呢?谁都不救啦!「对面的女孩看过来,看过来,看过来。」庄子分开著双腿像簸箕一样坐著,手中拿著一个瓦缶,边敲边唱,看著老婆和老妈慢慢地淹没在水中,满脸快快乐乐的样子。和砷:老婆和老妈落水就落水吧,反正我爱的是钱,钱就是我的老婆,钱就是我的亲妈。我说老婆和老妈呀,你们就不能穿差一点的衣服再掉到河里呀,可惜了你们头上的那些金钗手饰呀!「有啥你别有病,没啥你别没钱。」和呻一边看著他老婆和老妈慢慢地沉下去一边叹息著。王勃:手心手背都是肉,老婆是自己最爱的人,老妈是自己最亲的人,怎么办呢?不管它,先跳下去,看看离谁最近就先救谁吧。王勃扑通一声跳了下去。「不好,我忘了自己不会游泳了。」王勃咕噜噜地喝了几口水,也慢慢地沉了下去。一代才子王勃就是因为此事溺水而死的。孙悟空:俺是从石头缝里蹦出来的,没有老妈。所以不存在老妈落水的问题;俺是个和尚,没有老婆。所以不存在老婆落水的问题。不存在老妈落水的问题,也不存在老婆落水的问题,就更不会存在老妈和老婆同时落水的问题 玩笑人生,玩转人间!!记得回帖哟!
