BOOK 2 UNIT 7
A. Translate the following paragraphs into Chinese.
A man in China in the past was usually subjected to the domination of 3 systems of authority (political authority, clan authority

dominated by the men (the authority of the husband). These 4 authorities —political, clan, religious, and spousal — were the 4
thick ropes binding the Chinese people, particularly the peasants. But women in today’s world have the right to conct state
affairs, manage economic and cultural undertakings, and administer social affairs through various channels and in various

男子平等的选举权和被选举权。

Winston Churchill—His Other Life

Mary Soames

My father, Winston Churchill, began his love affair with painting in his 40s, amid disastrous circumstances. As First Lord of the Admiralty in 1915, he had been deeply involved in a campaign in the Dardanelles that could have shortened the course of a bloody world war. But when the mission failed, with great loss of life, Churchill paid the price, both publicly and privately: He was removed from the Admiralty and lost his position of political influence.
Overwhelmed by the disaster — "I thought he would die of grief," said his wife, Clementine — he retired with his family to Hoe Farm, a country retreat in Surrey. There, as Churchill later recalled, "The muse of painting came to my rescue!"
One day when he was wandering in the garden, he chanced upon his sister-in-law sketching with watercolours. He watched her for a few minutes, then borrowed her brush and tried his hand — and the muse worked her magic. From that day forward, Winston was in love with painting.
Delighted with anything that distracted Winston from the dark thoughts that overwhelmed him, Clementine rushed off to buy whatever paints and materials she could find. Watercolours, oil paints, paper, canvas — Hoe Farm was soon filled with everything a painter could want or need.
Painting in oils turned out to be Winston's great love — but the first steps were strangely difficult. He contemplated the blank whiteness of his first canvas with unaccustomed nervousness. He later recalled:
"Very hesitantly I selected a tube of blue paint, and with infinite precaution made a mark about as big as a bean on the snow-white field. At that moment I heard the sound of a motorcar in the drive and threw down my brush in a panic. I was even more alarmed when I saw who stepped from the car: the wife of Sir John Lavery, the celebrated painter who lived nearby.
"'Painting!' she declared. 'What fun. But what are you waiting for? Let me have the brush — the big one.' She plunged into the paints and before I knew it, she had swept several fierce strokes and slashes of blue on the absolutely terrified canvas. Anyone could see it could not hit back. I hesitated no more. I seized the largest brush and fell upon my wretched victim with wild fury. I have never felt any fear of a canvas since."
Lavery, who later tutored Churchill in his art, said of his unusual pupil's artistic abilities: "Had he chosen painting instead of politics, he would have been a great master with the brush."
In painting, Churchill had discovered a companion with whom he was to walk for the greater part of his life. Painting would be his comfort when, in 1921, the death of his mother was followed two months later by the loss of his and Clementine's beloved three-year-old daughter, Marigold. Overcome by grief, Winston took refuge at the home of friends in Scotland — and in his painting. He wrote to Clementine: "I went out and painted a beautiful river in the afternoon light with red and golden hills in the background. Many loving thoughts.... Alas, I keep feeling the hurt of Marigold."
Life and love and hope slowly revived. In September 1922 another child was born to Clementine and Winston: myself. In the same year, Winston bought Chartwell, the beloved home he was to paint in all its different aspects for the next 40 years.
My father must have felt a glow of satisfaction when in the mid-1920s he won first prize in a prestigious amateur art exhibition held in London. Entries were anonymous, and some of the judges insisted that Winston's picture — one of his first of Chartwell — was the work of a professional, not an amateur, and should be disqualified. But in the end, they agreed to rely on the artist's honesty and were delighted when they learned that the picture had been painted by Churchill.
Historians have called the decade after 1929, when Winston again fell from office, his barren years. Politically barren they may have been, as his lonely voice struggled to awaken Britain to the menace of Hitler, but artistically those years bore abundant fruit: of the 500-odd Churchill canvases in existence, roughly half date from 1930 to 1939.
Painting remained a joy to Churchill to the end of his life. "Happy are the painters," he had written in his book Painting as a Pastime, "for they shall not be lonely. Light and colour, peace and hope, will keep them company to the end of the day." And so it was for my father.

误 会

佚名

他头发蓬乱，衣着肮脏，口袋里只有35美分。在马里兰州的巴尔的摩，他登上一辆公共汽车并径直走向了洗手间。他想如果他躲在洗手间里，便可以不付钱就乘车去纽约。但是坐在公共汽车后面的一位乘客看见了他。她拍了拍她前面那位乘客的肩膀说：“洗手间里有个流浪汉。告诉公共汽车司机。”那位乘客轻轻地拍了一下坐在他前面的人，说道：“告诉公共汽车司机，洗手间里有个流浪汉。

这口信通过一个又一个的乘客传到了公共汽车的前边。但在这一过程的某个环节，口信变了。当它传到公共汽车司机那儿时，已经不是“洗手间里有个流浪汉”，而是“洗手间里有颗炸弹”。司机马上在公路边停下车来并用无线电通知了警察。当警察到达时，他们让乘客下车并且远离汽车。然后他们关闭了那条公路。那很快就造成了15英里长的交通堵塞。警察在警犬的帮助下，在公共汽车上搜查了两个小时。当然，他们没有发现什么炸弹。

两个发音相似的英语单词给一个想从洛杉矶飞往加利福尼亚州奥克兰的人也造成了麻烦。他的问题始于洛杉矶机场。他以为听到广播中宣布了他的航班，所以他走向登机门，出示了机票并登上了飞机。起飞20分钟后，这人开始担心起来。奥克兰在洛杉矶的北边，但是飞机似乎正在向西飞，而当他向窗外望去时，他所能看到的全是大海。“这架飞机是去奥克兰吗?”他问航班服务员。航班服务员倒抽了一口冷气，“不，”她说。“我们去奥克兰——新西兰的奥克兰。”

因为有这么多英文单词发音相似，讲英语者之间的误会并不罕见。并非所有的误会都会导致公路关闭或乘客飞错大陆。大多数误会远没有这么严重。每天讲英语的人会相互问这样的问题:“你是说七十还是十七?”“你是说你能来还是不能来?”发音相似的单词对把英语作为第二语言的人来说，特别容易让人混淆。

一天早晨，一位生活在美国的韩国妇女到上班地点时，她的老板问她：“你拿到盘子了吗?” “没有……”她回答说，心里却在纳闷，不知道他到底是什么意思。她在办公室工作。老板为什么问她盘子的事呢？一整天她都对老板的怪问题感到纳闷，但又不好意思开口问他。到了5点，当她准备回家时，她的老板说:“明天请准时上班。你今天早晨迟到了15分钟” “对不起，”她说。“我的车发动不起来，而且……” 突然她停止了讲话并开始微笑起来。她这时才明白老板并没有问她“你拿到盘子了吗？”他问的是“你是不是起来晚了？”

Auckland 和Oakland。“一个盘子”和“起晚”。当发音相似的单词引起误会时，也许最好的处理方式就是一笑了之并从错误中吸取教训。当然，有时候很难笑得出来。那个没到Oakland却去了Auckland的人是不会想笑的。但即使是那场误会，最终的结局也还不错。那家航空公司支付了那人在新西兰的旅馆住房和用餐的费用，还支付了他飞回加利福尼亚的费用。“ 哦，还好，”那人后来说，“我一直就想要看看新西兰的。”

The 20th century procedscientific and technological changes at a dizzying pace – greater than in anyother century in history. But the 21st century, the dawn of the new millennium,may well see even more dramatic changes driven by advances in science andtechnology.
20世纪科学和技术的变化，以令人目眩的速度 - 大于在其他任何一个世纪的历史。但进入21世纪，新千年的曙光，很可能看到在科学和技术的进步带动下更为剧烈的变化。

On these pages are my predictions for thetop scientific developments we’ll see in the next 100 years, in the order I thinkthey’ll happen.
在这些页面上是我对顶级的科学发展的预测，我们会看到，在未来的100年中，我认为他们会发生的顺序。

我们将会知道我们是从哪里来的

宇宙为什么会存在？自从1920年，科学家们就知道宇宙在扩大。这意味着宇宙在过去一个确定的时间就形成了。他们甚至制定了详尽地描绘宇宙从一开始到现在的演变的理论。

在接下来的几十年里，由功率极大的新型望远镜所带来的数据以及我们队物质在宇宙初期极度高温高压下活动方式的进一步了解都会使这些理论更加精确。

我们将破译基因密码并且征服癌症

在19世纪的歌剧中，如果女主角在第一幕中咳嗽的话，观众就知道她将在第三幕中死于肺结核。但是由于20世纪的抗生素，那些曾经的不治之症现在只要吃些药就没事了。

随着科学家对基因密码和细胞在分子层面上的活动方式了解的更多，许多严重的疾病-例如癌症-对人类的威胁将会变得越来越小。通过使用制造的具有治疗功效的病毒，医生们能够用健康的基因代替那些会导致癌症的破坏的DNA。

我们将活的更久

如果正常的生长过程是基于我们细胞里的一场可以看到的竞赛--一场对我们DNA的破坏与我们体内细胞修复这种破坏之能力之间的竞赛—然后21世纪先进的基因药物可能会让我们控制住甚至逆转这个过程。

但是在我们让科学家们做更多之前，请相想：我们真的想要在一个没人会变老、因为这个星球只能承受那么多的人而使孩子越来越少的星球上生活吗？那么新的思想从何而来？我们在空余时间能做什么？还有，你真的愿意做一个经理助理500年吗？

我们将管理地球

在新千年，我们将不再谈论天气，将会为它做些什么。

我们会逐渐认识到如何预测人类活动对地球气候和生态系统的影响。随之而来的是，人们将会越来越愿意运用那些知识来管理我们对这个星球所做的。地球将会被像管理一个农场或工厂那样管理。

我们将会有一个大脑的线路图

这是真正的21世纪最后的未知领域：大脑是我们所知道的最复杂的系统。它包含了将近1000亿个神经元，这1000亿个神经元相互关联。在21世纪早期，我们将运用先进的磁共振成像形式绘制详细的人脑神经元运作。我们能够确切地说，当你在读一个字，说一个字，想到一个字等等，是神经元在运作。

因此，第五个预测使我们兜了一圈，并且意识到在认识宇宙中最困难的可能是我们脑壳里的这个3磅重的器官—让我们从最初去认识宇宙。
