1、THE RETURN OF THE DINOSAURS？恐龙的回归？

2、The possibility of cloning fierce and extinct wild animals has always excited film makers。

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。

3、And they are not the only ones！

然而他们并不是唯一对此感到兴奋的人。

4、The popularity of films such as Jurassic Park， in which a scientist clones several kinds of extinct dinosaurs， proves how the idea struck a mixture of fear and excitement into people's hearts。

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。类似这样的电影很受欢迎，证明了这一想法使人们感到既兴奋又恐惧。

5、But in fact we are a long way from being able to clone extinct animals。

但事实上，想要克隆绝种动物，我们还要很长的路程要走。

6、Scientists are still experimenting with cloning mammals。

科学家们现在还在进行克隆哺乳动物实验。

7、This is because the cloning of mammals is still a new science and its story only began seriously in the 1950s as this list shows：

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年代才开始进行认真研究的，如下表所示：

8、From time to time people suggest that extinct animals like dinosaurs， can possibly be brought back to life through cloning。

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。

9、Unfortunately， with what we know now， this is either impossible or unsuitable。 There are many reasons。

不幸的是，据我们现在所知这是不可能的，也是不合适的。其原因有很多：

10、The initial requirement is that you need perfect DNA （which gives information for how cells are to grow）。

首先要求你有完好的DNA，以提供有关细胞将如何生长的信息。

11、All efforts of cloning an animal will be in vain if there is not enough diversity in the group to overcome illnesses。

如果某个动物群体没有足够的多样性以战胜疾病，那么克隆这种动物的所有努力都将是无用的。

12、Diversity in a group means having animals with their genes arranged in different ways。

群体的多样性是指这群动物的基因要以不同的方式排列。

13、The advantage is that if there is a new illness some of these animals may die， but others will survive and pass on the ability to resist that disease to the next generation。

其优点是，如果发生了某种新的疾病，这类动物中的一些可能会死去，而另外一些却能存活下来，并且把这种免疫力传给下一代。

14、The great drawback to cloning a group of animals is that they would all have the same arrangement of genes and so might die of the same illness。 Then none of them would be left to continue the species。

经过克隆的动物群体的最大缺点是：它们的基因排列有可能完全相同，因而它们有可能会死于同一种疾病，这样它们也可能一个也留不下来传种接代了。

15、It would be unfair to clone any extinct animals if they were to live in a zoo。

你如果克隆出任何绝种动物，而它们必须生活在动物园里那是不公平的。

16、A suitable habitat would be needed for them to lead a natural life。

它们需要适当的栖息地过正常的野生生活。

17、Based on what we know now， you cannot clone animals that have been extinct longer than 10，000 years。

就我们现在所知，你不可能克隆那些已经绝种了一万年以上的动物。

18、Actually， dinosaurs disappeared 65，000，000 years ago。

事实上恐龙在6，500万年以前就已经消失了。

19、So the chance of dinosaurs ever returning to the earth is merely a dream。

所以说恐龙回归地球的可能性仅仅是个梦想罢了。

第一单元课文翻译:

已发送请查收CALIFORNIA California 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 AMERCANS Exactly 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 SPANISH In 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. RUSSIANS In 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 MINERS In 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 the thirty-first federal state of the USA in 1850, it was already a multicultural society. LATER A RRIVALS Although Chinese immigrants began to arrive during the Gold Rush Period, it was the building ofthe 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 ARRIVALS In 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 FUTURE People 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. 美国加州 加州是美国第三大州，但人口最多。它也有被在美国最多元文化的国家的区别，有吸引了来自世界各地的人们。海关和移民的语言活在他们的新家园。这种文化的多样性是不奇怪当你知道美国加州的历史。 母语吴磊，阿拉伯 究竟当第一人抵达我们现在的加州所知，没有人真正知道。但是，很可能是在加利福尼亚州印第安人生活在至少1.5万年以前。科学家认为，这些定居者在越过白令海峡的北极通过大陆桥的存在意味着在史前时期到美国。在16世纪之后，欧洲人的到来，当地人民深受其害。数以千计的人死亡或奴役。此外，许多人死于由欧洲人带来的疾病。然而，一些幸存下来这些可怕的时代，今天有更多的印第安人居住在加州的比任何其他国家。 西班牙 在18世纪由西班牙统治加州。西班牙士兵首次抵达南美洲在16世纪初，当他们又打了当地人民对他们的土地了。两个世纪后，西班牙已经定居在南美洲的大部分地区和沿我们现在呼吁美国西北海岸。第一届西班牙语到加州，大部分是宗教的男子，其部是教天主教的本地人。 1821年，墨西哥人民从西班牙获得独立。加州则成为墨西哥的一部分。在1846年，美国宣布对墨西哥的战争，战争结束后由美国获胜，墨西哥不得不放弃到美国加利福尼亚州。但是，仍然有一个强大的国家西班牙的影响力。这就是为什么今天超过40％的加州发言作为第一或第二语言的西班牙语。 俄罗斯 在19世纪初，俄罗斯猎人，谁原本去阿拉斯加，开始在加利福尼亚州定居。今天，大约有2.5万俄罗斯和美国在旧金山附近居住。 淘金者 1848年，不久之后，美国与墨西哥战争，是在加利福尼亚州发现金矿。发展成为从世界各地吸引了人们快速致富的梦想。最近的，因此，第一个到达，是南美和美国人民。来自欧洲和亚洲然后冒险家紧随其后。事实上，很少有达到了他们的致富梦想。有些死亡或回家，但多数仍留在加州，尽管困难很大，使自己的生活。他们定居在新市镇或农场。由加州当选成为1850年的第三十一次的美国联邦州时，已经是一个多元文化的社会。 后来，一位RRIVALS 虽然中国移民开始在到达淘金时期，这是建设 从西到东的铁路网络沿岸，在19世纪60年代带来更大的编号，以加利福尼亚州。今天，中国的美国人居住在加州各地，虽然很大一部分选择了留在“唐人街”，洛杉矶和旧金山。 其他如意大利移民，主要是渔民，但也葡萄酒生产商，在加利福尼亚州来到了19世纪后期。 1911年从丹麦建立了一个移民城市自己，今天仍然保持了他们的丹麦文化。到1920年的电影业和好莱坞，加州成立。该行业的繁荣吸引了包括许多犹太人的欧洲人。今天，加利福尼亚州的美国第二大犹太居民。 日本农民开始在加利福尼亚州到达20世纪初，80年代以来，很多有在那里定居。来自非洲人民一直生活在加利福尼亚州自19世纪初，当他们从墨西哥北部。然而，更抵达1945年至1942年之间工作的船舶和飞机产业。 近来港的移民 在最近数十年来，加州有更多的人成为家来自亚洲，包括韩国，柬埔寨，越南和老挝。自20世纪70年代初，计算机行业吸引印度人和巴基斯坦人加州。 的未来 来自世界各地的人，受气候和生活方式所吸引，但移民到美国加州。可以相信，不久的民族组合将是如此之大，不会有明显的主要种族或文化团体，而是一个多种族和文化的交融。
