人教版高中英语选修8 课文及翻译选修8 Unit 1 A land of diversity-ReadingCALIFORNIACalifornia is the third largest state in the USA but has the largest population. It also has the distinction of being the most multicultural state in the USA, having attracted people from all over the world. The customs and languages of the immigrants live on in their new home. This diversity of culture is not surprising when you know the history of California.NATIVE AMERCANSExactly when the first people arrived in what we now know as California, no one really knows. However, it is likely that Native Americans were living in California at least fifteen thousand years ago. Scientists believe that these settlers crossed the Bering Strait in the Arctic to America by means of a land bridge which existed in prehistoric times. In the 16th century, after the arrival of the Europeans, the native people suffered greatly. Thousands were killed or forced into slavery. In addition, many died from the diseases brought by the Europeans. However, some survived these terrible times, and today there are more Native Americans living in California than in any other state.THE SPANISHIn the 18th century California was ruled by Spain. Spanish soldiers first arrived in South America in the early 16th century, when they fought against the native people and took their land. Two centuries later, the Spanish had settled in most parts of South America and along the northwest coast of what we now call the United States. Of the first Spanish to go to California, the majority were religious men, whose ministry was to teach the Catholic religion to the natives. In 1821, the people of Mexico gained their independence from Spain. California then became part of Mexico. In 1846 the United States declared war on Mexico, and after the war won by the USA, Mexico had to give California to the USA. However, there is still a strong Spanish influence in the state. That is why today over 40 of Californians speak Spanish as a first or second language.RUSSIANSIn the early 1800s, Russian hunters, who had originally gone to Alaska, began settling in California. Today there are about 25,000 Russian-Americans living in and around San Francisco.GOLD MINERSIn 1848, not long after the American-Mexican war, gold was discovered in California. The dream of becoming rich quickly attracted people from all over the world. The nearest, and therefore the first to arrive, were South Americans and people from the United States. Then adventurers from Europe and Asia soon followed. In fact, few achieved their dream of becoming rich. Some died or returned home, but most remained in California to make a life for themselves despite great hardship. They settled in the new towns or on farms. By the time California elected to become thethirty-first federal state of the USA in 1850, it was already a multicultural society.LATER A RRIVALSAlthough Chinese immigrants began to arrive during the Gold Rush Period, it was the building of the rail network from the west to the east coast that brought even larger numbers to California in the 1860s. Today, Chinese-Americans live in all parts of California, although a large percentage have chosen to stay in the "Chinatowns" of Los Angeles and San Francisco.Other immigrants such as Italians, mainly fishermen but also wine makers, arrived in California in the late 19th century. In 1911 immigrants from Denmark established a town of their own, which today still keeps up their Danish culture. By the 1920s the film industry was well established in Hollywood, California. The industry boom attracted Europeans including many Jewish people. Today California has the second largest Jewish population in the United States.Japanese farmers began arriving in California at the beginning of the 20th century, and since the 1980s a lot more have settled there. People from Africa have been living in California since the 1800s, when they moved north from Mexico. However, even more arrived between 1942 and 1945 to work in the ship and aircraft industries. MOST RECENT ARRIVALSIn more recent decades, California has become home to more people from Asia, including Koreans, Cambodians, Vietnamese and Laotians. Since its beginning in the 1970s, the computer industry has attracted Indians and Pakistanis to California. THE FUTUREPeople from different parts of the world, attracted by the climate and the lifestyle, still immigrate to California. It is believed that before long the mix of nationalities will be so great that there will be no distinct major racial or cultural groups, but simply a mixture of many races and cultures.GEORGE’S DIARY 12TH—14TH JUNEMonday 12th, JuneArrived early this morning by bus. Went straight to hotel to drop my luggage, shower and shave. Then went exploring. First thing was a ride on a cable car. From top of the hill got a spectacular view of San Francisco Bay and the city. Built in 1873, the cable car system was invented by Andrew Hallidie, who wanted to find a better form of transport than horse-drawn trams. Apparently he'd been shocked when he saw a terrible accident in which a tram's brakes failed, the conductor could not control the situation and the tram slipped down the hill dragging the horses with it. Had a late lunch at Fisherman's What. This is the district where Italian fishermen first came to San Francisco in the late 19th century and began the fishing industry. Now it's a tourist area with lots of shops, sea food restaurants and bakeries. It's also the place to catch the ferry to Angel Island and other places in the Bay.Did so much exploring at Fisherman's What. Am exhausted and don't feel like doing anything else. Early bed tonight!Tuesday 13th, JuneTeamed up with a couple from my hotel (Peter and Terri) and hired a car. Spent all day driving around the city. There's a fascinating drive marked out for tourists. It has blue and white signs with seagulls on them to show the way to go. It's a 79km round-trip that takes in all the famous tourist spots. Stopped many times to admire the view of the city from different angles and take photographs. Now have a really good idea of what the city's like.In evening, went to Chinatown with Peter and Terri. Chinese immigrants settled in this area in the 1850s. The fronts of the buildings are decorated to look like old buildings in southern China. Saw some interesting temples here, a number of markets and a great many restaurants. Also art galleries and a museum containing documents, photographs and all sorts of objects about the history of Chinese immigration, but it is closed in the evening. Will go back during the day. Had a delicious meal and then walked down the hill to our hotel.Wednesday 14th, JuneIn morning, took ferry to Angel Island from the port in San Francisco Bay. On the way had a good view of the Golden Gate Bridge. From 1882 to 1940 Angel Island was a famous immigration station where many Chinese people applied for right to live in USA. The cells in the station were very small, cold and damp; some did not even have light but the immigrants had nowhere else to go. Their miserable stay seemed to be punishment rather than justice and freedom to them. They wrote poems on the walls about their loneliness and mourned their former life in China. In 1940 the civil authorities reformed the system so that many more Chinese people were able to grasp the opportunity of settling in the USA. Made me very thoughtful and thankful for my life today.选修8 Unit 2 Cloning-ReadingCLONING: WHERE IS IT LEADING US?Cloning has always been with us and is here to stay. It is a way of making an exact copy of another animal or plant. It happens in plants when gardeners take cuttings from growing plants to make new ones. It also happens in animals when twins identical in sex and appearance are produced from the same original egg. The fact is that these are both examples of natural clones.Cloning has two major uses. Firstly, gardeners use it all the time to produce commercial quantities of plants. Secondly, it is valuable for research on new plant species and for medical research on animals. Cloning plants is straightforward while cloning animals is very complicated. It is a difficult task to undertake. Many attempts to clone mammals failed. But at last the determination and patience of the scientists paid off in 1996 with a breakthrough - the cloning of Dolly the sheep.The procedure works like this:On the one hand, the whole scientific world followed the progress of the first successful clone, Dolly the sheep. The fact that she seemed to develop normally was very encouraging. Then came the disturbing news that Dolly had become seriously ill. Cloning scientists were cast down to find that Dolly's illnesses were more appropriate to a much older animal. Altogether Dolly lived six and a half years, half the length of the life of the original sheep. Sadly the same arbitrary fate affected other species, such as cloned mice. The questions that concerned all scientists were: "Would this be a major difficulty for all cloned animals? Would it happen forever? Could it be solved if corrections were made in their research procedure?"On the other hand, Dolly's appearance raised a storm of objections and had a great impact on the media and public imagination. It became controversial. It suddenly opened everybody's eyes to the possibility of using cloning to cure serious illnesses and even to produce human beings.Although at present human egg cells and embryos needed for cloning research are difficult to obtain, newspapers wrote of evil leaders hoping to clone themselves to attain their ambitions. Religious leaders also raised moral questions. Governments became nervous and more conservative. Some began to reform their legal systems and forbade research into human cloning, but other countries like China and the UK, continued to accumulate evidence of the abundant medical aid that cloning could provide. However, scientists still wonder whether cloning will help or harm us and where it is leading us.克隆一直在我们左右并且已经被大多数人接受。

新人教版英语选修八第二单元Using Language的课文译文恐龙的回归克隆凶猛和灭绝的野生动物的可能性一直使电影制片商感到兴奋。

然而他们并不是惟一对此感到兴奋的人。

在《侏罗纪公园》这部影片中，有一位科学家克隆了好几种不同的绝种恐龙。

这部电影很受欢迎，证明普通老百姓对这个问题是多么感兴趣。

事实上，要想克隆绝种动物，我们还有很长的路程要走。

科学家们现在还在进行克隆哺乳动物试验，这是因为克隆哺乳动物仍然还是一门新的科学，它是从20世纪50年代才开始认真进行研究的，如下表所示：20世纪50年代：克隆青蛙1996年：首次克隆哺乳动物（多莉羊）2000年：母牛生野牛2001年：中国首次克隆出双胞胎小牛2002年：首次克隆猫2005年：首次克隆狗20世纪70年代：用老鼠胚胎进行研究
1979年：对羊和老鼠的胚胎进行研究
1981年：首次对老鼠进行试验性的克隆1983年：首次对母牛进行试验性的克隆
......不时地会有人提议，克隆技术将有可能使地球上已经消失的动物（如恐龙）复活。

不幸的是，这是不可能的，也是不合适的。

新人教版英语选修八第三单元Using Language的课文译文亚历山大 .格雷厄姆 .贝尔亚历山大 . 格雷厄姆 . 贝尔 1847 年出生于苏格兰。

但在他还小的时候，他家就搬到了美国的波士顿。

他的母亲几乎全聋了，所以他有志于帮助聋人沟通，并从事聋人教育事业。

这一喜好促进他发了然麦克风。

他发现他把嘴唇放到母亲的额头上，并以必定的方式来挪动额骨，她就能够听懂他所说的话。

他以为一个人应当老是有好奇心理。

他最有名的一句话是：“有时走开平路，深入到林子里去。

每次当你这样做的时候，你必定会发现你从未见过的东西。

追踪下去，不断探究，不知不觉中，你就会发现某种值得思虑的东西占据着你的脑筋。

全部真实伟大的发现都是思虑的结果。

”正是这类对问题的探究精神造就了他那有名的发明—— 1876 年的电话。

贝尔并不是一开始就想要发明电话的，他原来想设计的东西是多路电报。

这类原始的电报是在一段距离顶用莫尔斯电码传达信息（莫尔斯电码是经过电线发出的以特定的序次敲击出的一连串点划），可是这样只好一次发一份电报。

贝尔想改良电报通信方式，以便同时能发出好几个信息。

他设计了一种机器，以使声波分红不一样的音调，进而有可能在同一时间里进行不一样的通话。

可是他发现这个问题很难解决。

有一天做实验，他把一根干草和一个聋子的耳朵连结起来。

贝尔发现，当他对这耳朵说话的时候，这根干草就把声波画在被烟熏过的玻璃上。

忽然间他灵光一闪，灵感来了。

假如声波能够以连续运动的电流形式复制的话，那么声波就能够沿着导线传递出去了。

在探究改良电报的过程中，贝尔发了然第一台电话机！贝尔完整懂得这项发明的重要性。

他写信告诉他的父亲说：“这样的一天马上到来。

到那时，电报线将会铺到各家各户，就像水和煤气通到各家各户同样。

朋友之间不用走开家就能够相互通话了。

”这项专利是 1876 年公布的，可是贝尔是在五天此后才跟他的助手华生通了第一次电话。

人教版高中英语选修8 课文及翻译选修8 Unit 1 A land of diversity-ReadingCALIFORNIACalifornia is the third largest state in the USA but has the largest population. It also has the distinction of being the most multicultural state in the USA, having attracted people from all over the world. The customs and languages of the immigrants live on in their new home. This diversity of culture is not surprising when you know the history of California.NATIVE AMERCANSExactly when the first people arrived in what we now know as California, no one really knows. However, it is likely that Native Americans were living in California at least fifteen thousand years ago. Scientists believe that these settlers crossed the Bering Strait in the Arctic to America by means of a land bridge which existed in prehistoric times. In the 16th century, after the arrival of the Europeans, the native people suffered greatly. Thousands were killed or forced into slavery. In addition, many died from the diseases brought by the Europeans. However, some survived these terrible times, and today there are more Native Americans living in California than in any other state.THE SPANISHIn the 18th century California was ruled by Spain. Spanish soldiers first arrived in South America in the early 16th century, when they fought against the native people and took their land. Two centuries later, the Spanish had settled in most parts of South America and along the northwest coast of what we now call the United States. Of the first Spanish to go to California, the majority were religious men, whose ministry was to teach the Catholic religion to the natives. In 1821, the people of Mexico gained their independence from Spain. California then became part of Mexico. In 1846 the United States declared war on Mexico, and after the war won by the USA, Mexico had to give California to the USA. However, there is still a strong Spanish influence in the state. That is why today over 40 of Californians speak Spanish as a first or second language.RUSSIANSIn the early 1800s, Russian hunters, who had originally gone to Alaska, began settling in California. Today there are about 25,000 Russian-Americans living in and around San Francisco.GOLD MINERSIn 1848, not long after the American-Mexican war, gold was discovered in California. The dream of becoming rich quickly attracted people from all over the world. The nearest, and therefore the first to arrive, were South Americans and people from the United States. Then adventurers from Europe and Asia soon followed. In fact, few achieved their dream of becoming rich. Some died or returned home, but most remained in California to make a life for themselves despite great hardship. They settled in the new towns or on farms. By the time California elected to become thethirty-first federal state of the USA in 1850, it was already a multicultural society.LATER A RRIVALSAlthough Chinese immigrants began to arrive during the Gold Rush Period, it was the building of the rail network from the west to the east coast that brought even larger numbers to California in the 1860s. Today, Chinese-Americans live in all parts of California, although a large percentage have chosen to stay in the "Chinatowns" of Los Angeles and San Francisco.Other immigrants such as Italians, mainly fishermen but also wine makers, arrived in California in the late 19th century. In 1911 immigrants from Denmark established a town of their own, which today still keeps up their Danish culture. By the 1920s the film industry was well established in Hollywood, California. The industry boom attracted Europeans including many Jewish people. Today California has the second largest Jewish population in the United States.Japanese farmers began arriving in California at the beginning of the 20th century, and since the 1980s a lot more have settled there. People from Africa have been living in California since the 1800s, when they moved north from Mexico. However, even more arrived between 1942 and 1945 to work in the ship and aircraft industries. MOST RECENT ARRIVALSIn more recent decades, California has become home to more people from Asia, including Koreans, Cambodians, Vietnamese and Laotians. Since its beginning in the 1970s, the computer industry has attracted Indians and Pakistanis to California. THE FUTUREPeople from different parts of the world, attracted by the climate and the lifestyle, still immigrate to California. It is believed that before long the mix of nationalities will be so great that there will be no distinct major racial or cultural groups, but simply a mixture of many races and cultures.GEORGE’S DIARY 12TH—14TH JUNEMonday 12th, JuneArrived early this morning by bus. Went straight to hotel to drop my luggage, shower and shave. Then went exploring. First thing was a ride on a cable car. From top of the hill got a spectacular view of San Francisco Bay and the city. Built in 1873, the cable car system was invented by Andrew Hallidie, who wanted to find a better form of transport than horse-drawn trams. Apparently he'd been shocked when he saw a terrible accident in which a tram's brakes failed, the conductor could not control the situation and the tram slipped down the hill dragging the horses with it. Had a late lunch at Fisherman's What. This is the district where Italian fishermen first came to San Francisco in the late 19th century and began the fishing industry. Now it's a tourist area with lots of shops, sea food restaurants and bakeries. It's also the place to catch the ferry to Angel Island and other places in the Bay.Did so much exploring at Fisherman's What. Am exhausted and don't feel like doing anything else. Early bed tonight!Tuesday 13th, JuneTeamed up with a couple from my hotel (Peter and Terri) and hired a car. Spent all day driving around the city. There's a fascinating drive marked out for tourists. It has blue and white signs with seagulls on them to show the way to go. It's a 79km round-trip that takes in all the famous tourist spots. Stopped many times to admire the view of the city from different angles and take photographs. Now have a really good idea of what the city's like.In evening, went to Chinatown with Peter and Terri. Chinese immigrants settled in this area in the 1850s. The fronts of the buildings are decorated to look like old buildings in southern China. Saw some interesting temples here, a number of markets and a great many restaurants. Also art galleries and a museum containing documents, photographs and all sorts of objects about the history of Chinese immigration, but it is closed in the evening. Will go back during the day. Had a delicious meal and then walked down the hill to our hotel.Wednesday 14th, JuneIn morning, took ferry to Angel Island from the port in San Francisco Bay. On the way had a good view of the Golden Gate Bridge. From 1882 to 1940 Angel Island was a famous immigration station where many Chinese people applied for right to live in USA. The cells in the station were very small, cold and damp; some did not even have light but the immigrants had nowhere else to go. Their miserable stay seemed to be punishment rather than justice and freedom to them. They wrote poems on the walls about their loneliness and mourned their former life in China. In 1940 the civil authorities reformed the system so that many more Chinese people were able to grasp the opportunity of settling in the USA. Made me very thoughtful and thankful for my life today.选修8 Unit 2 Cloning-ReadingCLONING: WHERE IS IT LEADING US?Cloning has always been with us and is here to stay. It is a way of making an exact copy of another animal or plant. It happens in plants when gardeners take cuttings from growing plants to make new ones. It also happens in animals when twins identical in sex and appearance are produced from the same original egg. The fact is that these are both examples of natural clones.Cloning has two major uses. Firstly, gardeners use it all the time to produce commercial quantities of plants. Secondly, it is valuable for research on new plant species and for medical research on animals. Cloning plants is straightforward while cloning animals is very complicated. It is a difficult task to undertake. Many attempts to clone mammals failed. But at last the determination and patience of the scientists paid off in 1996 with a breakthrough - the cloning of Dolly the sheep.The procedure works like this:On the one hand, the whole scientific world followed the progress of the first successful clone, Dolly the sheep. The fact that she seemed to develop normally was very encouraging. Then came the disturbing news that Dolly had become seriously ill. Cloning scientists were cast down to find that Dolly's illnesses were more appropriate to a much older animal. Altogether Dolly lived six and a half years, half the length of the life of the original sheep. Sadly the same arbitrary fate affected other species, such as cloned mice. The questions that concerned all scientists were: "Would this be a major difficulty for all cloned animals? Would it happen forever? Could it be solved if corrections were made in their research procedure?"On the other hand, Dolly's appearance raised a storm of objections and had a great impact on the media and public imagination. It became controversial. It suddenly opened everybody's eyes to the possibility of using cloning to cure serious illnesses and even to produce human beings.Although at present human egg cells and embryos needed for cloning research are difficult to obtain, newspapers wrote of evil leaders hoping to clone themselves to attain their ambitions. Religious leaders also raised moral questions. Governments became nervous and more conservative. Some began to reform their legal systems and forbade research into human cloning, but other countries like China and the UK, continued to accumulate evidence of the abundant medical aid that cloning could provide. However, scientists still wonder whether cloning will help or harm us and where it is leading us.克隆一直在我们左右并且已经被大多数人接受。
