As I have grown older I have also grown smaller. Over time my memory has developed so much that, like an elephant, I never forget anything I have been told! And my memory became so large that even I couldn't believe it! But I was always so lonely standing there by myself, until in the early 1960s they gave me a family connected by a network. I was able to share my knowledge with others through the World Wide Web.

Who am I ?
Over time I have been changed quite a lot. I began as a calculating machine in France in 1642. Although I was young I could simplify difficult sums. I developed very slowly and it took nearly two hundred years before I was built as an analytical machine by Charles Babbage. After I was programmed by an operator who used cards with holes, I could "think" logically and produce an answer quicker than any person. At that time it was considered a technological revolution and the start of my "artificial intelligence". In 1936 my real father, Alan Turing, wrote a book about how I could be made to work as a "universal machine" to solve any difficult mathematical problem. From then on, I grew rapidly both in size and in brainpower. By the 1940s I had grown as large as a room, and I wondered if I would grow any larger. However, this reality also worried my designers. As time went by, I was made smaller. First as a PC (personal computer) and then as a laptop, I have been used in offices and homes since the 1970s.

About once a year we are allowed to get together to play a game of football. I’m as big as a human. In fact, I look like one too. On the football team I’m a striker so I have to be able to run very fast. My computer chips help me to move and think like a human. For example, I have learned to signal to my teammates in computer language to give methe ball when I am open and have a good shot for a goal.My first football competition was in Nagoya, Japan several years ago. Last year our team wentto Seattle, Washington in the USA. We won second place. Personally, I think the team that wonfirst place cheated. They had developed a new type of program just before the competition. So we need to encourage our programmer to improve our intelligence too. We are determined to create an even better system. In a way our programmer is like our coach. She programs us with all the possible moves she has seen while watching human games. Then she prepares reliable moves to use if a new situation arises. In this way I can make up new moves using my “artificial intelligence”. I would really like to play against a human team, for I have been programmed to act just like them. After all, with the help of my electronic brain which never forgets anything, usingmy intelligence is what I’m all about!。

HEALTHY EATING
• There is much debate nowadays as to what makes up a healthy diet. For example, scientists have insisted for years that a big enemy of health is fatty food. However, there is increasing evidence that the real driver of poor health is not so much fatty food, as it is sugar. Heart disease is the number one killer of Americans.
• 当下，何为健康饮食仍众说纷纭。例如，多年来科学家一直认为健康的大敌是高 脂肪食物。然而，越来越多的证据表明，导致不良健康的真正因素并非高脂肪食 物，而是糖分。心脏病是美国人的头号杀手。
• And in America, people who receive 25%o of their daily calories or more through sugar are twice as likely to die from heart disease than people who receive less than 10% a day (Journal of the American Medical Association, 2014). This is hy the rest of their diet might be. Put more simply, while people continue to argue over whether or not fatty food is dangerous, we already know that sugar is a killer.

高中英语必修二课文参考译文第一单元文化遗产阅读一寻找琥珀屋普鲁士国王腓特烈·威廉一世从未想过他送个普鲁士人民伟大的礼物会有一点如此惊奇的历史。
这个礼物是因为由几吨琥珀制成而命名的琥珀屋。
这些被挑选的琥珀都有着像蜂蜜一样漂亮的黄棕色。
这间屋的设计是当时最流行的奇特的风格。
这同样是一件花了当时最好的艺术家大约十年用黄金和珠宝修饰制成的宝物。
事实上，这间屋不是制来当礼物的。
这是为腓特烈一世的领土而设计的。
然而，普鲁士下一任国王同样是琥珀屋的拥有者，腓特烈威廉一世决定不保留琥珀屋。
在1716年他把琥珀屋送给了彼得大帝。
作为报答，沙皇给了腓特烈一队他最好的士兵。
因此琥珀屋成为了沙皇避寒圣地圣彼得堡的一部分。
琥珀屋作为一个大概四米长的只为重要访客的小接待处。
后来，叶卡捷琳娜二世把琥珀屋在圣彼得堡之外的一个她避暑的地方。
她让她的艺术家加了跟多的细节在里面。
在1770年琥珀屋完全成了她想要的样子。
接近600只蜡烛在屋内燃烧着，把镜子和图画都照得像金子一样。
令人伤心的，虽然被誉为是世界奇迹之一的琥珀屋现在丢失了。
在1941年9月，纳粹军队在圣彼得堡附近。
这正是两个国家在交战的时候。
在纳粹去到避暑地方之前，俄国人民能够从琥珀屋里搬走一些家具和小的艺术品。
然而，一些纳粹神秘的偷走了琥珀屋。
至少两天内100000多片琥珀被放进27个木箱里。
这些箱子无疑会被放进一艘去往当时德军驻扎的菠萝的海的哥尼斯堡的船上。
之后，琥珀屋发生了神马仍然是个迷。
最近，俄国和德国人民在避暑的地方制造了一座新的琥珀屋。
通过研究之前的琥珀屋的照片，他们制造了一座新的琥珀屋像旧的那座一样。
在2003年它被圣彼得堡的人民用来庆祝这座城市的300岁生日。
阅读二一个事实还是一个观点神马是事实？是一些人们相信的东西吗？不！事实是可以被证明的任何事。
例如，可以证明中国人口比世界上任何其他国家的人口都要多。
这是一个事实。
那么神马是一个观点？一个观点是人们相信那是真的但还没有被证明的。

Unit 3 THE INTERNETSTRONGER TOGETHER: HOW WE HAVE BEEN CHANGED BY THE INTERNETMuch has been written about the wonders of the World Wide Web. There are countless articles telling us how the Internet has made our life more convenient. We no longer have to wait in line or carry cash around when we go shopping. We can get the most updated information from large databases. We can download software, documents, and images whenever we need them. But the Internet has done much more for people than simply make life more convenient. People’s lives have been changed by online communities and social networks.Jan Tchamani, an English teacher in Birmingham, UK, suddenlydeveloped a serious illness and had to quit her job. At age 50. she found herself out of work and stuck at home with only her computer to keep her company. After a while, she discovered that surfing the Internet could help her feel less lonely and bored. She could listen to music, watch films, play games, and explore the world. She also joined an online group where she could talk about her problems and get support and advice from others. She realised that one of the greatest benefits of the Internet was its ability to remove the distance that actually exists between people.She was so inspired by the people she met online that she decided to start an IT club to teacher older people how to use computers and the Internet. She and her friends now organise events and collect money for private teachers. Many people have been helped by the club. A 59-year-old man learnt how to apply for work online and found a great job. Now that he works and can take care of himself, his daughter has time to study atuniversity. A 61-year-old woman who was living alone has started a small online company together with two friends. She no longer feels lonely, and her company has become quite successful.Jan has started taking online classes to learn more about how to use the Internet to make society better. She believes that it is highly important to bridge the digital divide and make sure that everyone has access to the Internet and knows how to use technology. Her next goal is to start a charity website to raise money for children in poor countries.Jan’s life has been greatly improved by the Internet. “when you go through tough times, you meet others who are facing similar challenges.” Jan says. “Thinking about other people’s situation inspired me to offer help.”Reading and writingToday I thought I’d blog about a question that has been asked many times-how do you stay safe online and avoid bad experiences on the Internet? I’m not an expert, but many years as a blogger have taught me a thing or two.First of all, there’s the golden rule of the Internet: if you see orread something that makes you feel uncomfortable, leave the site immediately. Don’t post comments or click on anything. Second, protect you privacy. Don’t give out your address or phone number. Someone might use the information to steal your identity. Identity theft is a common and serious problem. Third, be polite. Being online is no excuse for being rude, and you don’t want to become a target for a troll or cyberbully. A troll is a person who posts comments or questions in order to stir up trouble online. Trolls often use several false names so that they can stay on a site. A cyberbully uses the Internet to be mean to others. Like a troll, a cyberbully will also write something mean but it is usually directed at particular people. He or she may also post embarrassing photos and information about these people. However, the more polite you are, the less likely it is you will be attacked.Have you had any bad experiences online, or do you have some good advice for staying safe? Post your comments below!。
