Unit 3 Science versus natureSection Ⅰ Welcome to the unit& Reading-Pre-readingThe Chinese scientist behind the development of the world's largest cloning factory in Tianjin, China, claims (声称) that the facility (设备) possesses the technology to clone humans. He added that the only thing holding them back from cloning a person is the fear of how the public would react to it.The giant cloning factory, which is due to open within the next seven months, is backed by Boyalife group in collaboration with South Korean company Sooam Biotech Research Foundation. It plans to be cloning 1 million cows a year by 2020, and also aims to clone other animals such as racehorses and police dogs. “Everything in the supermarket looks good —it's almost all shiny, goodlooking, and uniformly shaped. For animals, we weren't able to do that in the past. But with our cloning factory, we choose to do so now，” Boyalife CEO Xu Xiaochun said.There are different opinions when it comes to whether the cloned beef is safe for human consumption. The US Food and Drug Administration says it is, but the European parliament (议会) disagrees and has backed a ban on cloned animals andproduce in the food chain, reports the DailyMail.Section Ⅰ Welcome to the unit & Reading —PrereadingThe perfect copyScientists have announced①that they have cloned② the first human embryo ③.

课时跟踪练(一) Welcome to the unit & Reading Ⅰ.阅读理解APlant cloning has been an agricultural technique used by farmers and gardeners for centuries. Grafting (嫁接) is a common form of plantcloning. Many plants in nature actually clone themselves andreproduce asexually.Cloned plants are much more predictable than normal plants,so their yield (产量) is more reliable. Cloned plants also reproduce faster, limiting the amount of time between planting and harvesting. It is also often cheaper to produce seeds through cloning than through traditional methods. Plants can essentially be optimized so that farmers or individual growers always have the best seeds available. With more yield at a faster rate, farms can produce more food for more people while decreasing overall costs.Cloning can be used to wipe out diseases that previously killed off entire fields of crops. This would make plants immune (免疫的) to the kinds of diseases that farmers and gardeners around the world fear each year. Crop failures due to disease and virus could become a thing of the past. Also, plants that are near extinction can be brought back to life through cloning.Through cloning scientists can develop “super” fruits and vegetables of superior nutritional quality. This could make for a healthier population overall. This is already being done through selective pollination (授粉), and genetic cloning could take it to the next level.By plant cloning we have a population of identical plants and all these plants equally suffer from the same diseases, but in nature the weak would die and the strong would survive. While there are some dangers to consider with plant cloning, there are plenty of benefits that could prove vital to the propagation (繁衍) of the human species.语篇解读：本文主要讲了克隆植物的好处：增加农作物产量、提高植物的免疫力、提高水果和蔬菜的质量等。
Unit 3 Science versus nature基因联系听觉和触觉Sound and touch may seem completely separate, except possibly when playing the game Operation. But it turns out that the two senses are actually quite entwined: a new study finds that people with hearing issues often also have problems with touch.听觉和触觉似乎是彼此完全独立的——除了在玩军事游戏的时候需要二者都用上。
但事实证明，这两个感官实际上是紧密联系的。
一项新的研究发现，有听觉障碍的人往往也存在触觉障碍。
Researchers compared sets of twins, some identical and some fraternal. The identical twins, obviously, have the same genome and thus the same mutations. The fraternal twins have genetic differences. Other subjects in the study were congenitally deaf.研究人员比较了几对双胞胎，其中既有同卵双生胎也有异卵双生胎。
很明显，同卵双生胎具有相同的基因，因此它们的变异也相同。
异卵双生胎的则存在基因差异。
其他的受试者则先天性耳聋。
To determine how acute their hearing was, the subjects reported whether they could hear various high frequencies. To evaluate touch they were asked to differentiate different surfaces with their fingertips.为了确定他们的听觉是否敏锐，研究人员让受试者说出他们是否能听到各种各样的较高频率。

克隆：将我们引向何方？
克隆一直与我们同在。
这是一种用来生产与原型完全相同的动植物的方法。
1996年，科学家们胜利克隆出多莉羊。
一方面，整个科学界都在关注着首例胜利的克隆动物多莉羊的成长。
从总体上来说，科学家们因为其突出的科学突破而得到了人们的称赞。
另一方面，多莉的出生引起了一阵剧烈的反对。
它突然打开了人们的眼界，看到了有可能利用克隆技术来生产能够用来拯救人类生命的宝贵的组织和器官。
然而，有些科学家已经采用这一技术目的是克隆出人类，尽管在大部分国家这是不合法的。
克隆人类已经引起了很多担忧。
很多人坚持认为如果我们把生命当作儿戏，我们可能会制造很多问题。
从我个人观点来看，我不赞成克隆人类。
我们应当为我们行为的后果负责。
我们应当严谨对待克隆人类。
当我们决定是否克隆人类的时候，我们应该把各种因素考虑在内。
简言之，我们可以努力推进克隆技术来满足我们的需要而不是破坏我们的生活。
