1、Module 5 课时跟踪检测（一） Introduction & Reading Pre reading阅读理解ALast spring, I worked in Washington DC. There I visited Fords Theater and looked at Abraham Lincolns impressive memorial (纪念碑)But at the National Museum of Health and Medicine, my nose could almost touch pieces of the man himself: a lock of h
2、is hair, pieces of his skull and a handkerchief with his blood on it. As I stood there, I wondered, “Could we clone Abraham Lincoln？”Since Dolly the sheep was cloned in 1996, scientists have cloned mammals from mice to mules, but weve never cloned a human. Maybe its a horrible desire, but if we ever
3、 decided to clone someone, I would vote for Abraham Lincoln.After Abraham Lincoln was shot, his doctors and friends collected bits of his skull and bloody pieces of cloth for autopsy (尸检). Locks of his hair were passed around like holy relics. Long before they knew about DNA, these pieces of Lincoln
4、 represented the essence (本质) of the man.While we do have his genes, we probably dont have the entire DNA sequence needed for cloning. Sheryl Bernauer, lab supervisor for the DNA Sequencing Facility at UC Davis, said that when cells die over time, the DNA becomes less useful. The DNA in Lincolns 145
5、yearold bloodstains and hair is probably futile for cloning. “The hair itself would be very hard to get the entire DNA sequence from unless you have a complete follicle (毛囊)，” Bernauer said. We dont have any of Lincolns follicles, so thats a nogo.Still, its interesting to think about how the develop
6、ment of cloning has changed the way we view human remains. Humans have always honored the dead, but now we know that in DNA at least part of the dead lives on.语篇解读：作者思考了我们是否可以克隆出Abraham Lincoln的问题，但目前来说条件不允许。1At the National Museum of Health and Medicine, the author _.Atouched pieces of Abraham Linc

10、A sequence from unless you have a complete follicle”可知，完整的毛囊里面有完整的基因序列。BIf you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise and as a result, we are ageing unnecessarily
11、soon.Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the process of ageing could be slowed down. With a team of colleagues at Tokyo National University, he set abou
12、t measuring brain volumes of a thousand people of different ages and varying occupations. Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side sections of the brain, which relate to intellect (智力) and emotion, and determine the human characte
13、r. (The rear section of the brain, which controls functions like eating and breathing, does not contract with age, and one can continue living without intellectual or emotional faculties.) Contraction of front and side parts as cells die off was observed in some subjects in their thirties, but it wa
14、s still not evident in some sixtyyearolds and seventyyearolds. Matsuzawa concluded from his tests that there is a simple remedy to the contraction normally associated with age using the head. The findings show in general terms that contraction of the brain begins sooner in people in the country than
15、 in the towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking brains as the farm workers, bus drivers and shop assistants. Matsuzawas findings sho
16、w that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. “The best way to maintain good blood circulation is through using the brain，” he says, “Think hard and engage in conversation. Dont rely on pocket calculat

19、选C。6The doctors test shows that _. Aour brains shrink as we grow older Bthe front section of the brain does not shrink Csixtyyearolds have better brains than thirtyyearoldsDsome peoples brains have contracted more than other peoples解析：选D细节理解题。由倒数第二段“The findings show in general terms that contractio
20、n of the brain begins sooner in people in the country than in the towns.”可知医生们的测试发现，一般而言，乡下人比城市里的人的大脑萎缩得更早。故选D。C The Hall of Presidents is about to get terrible, at least if Disneys researchers get their way.Thats because theyre face cloning people at a laboratory in Zurich in order to create the mo
21、st realistic animatronic (电子动物的) characters ever made.First of all, yes, Disney has a laboratory in Zurich.Its one of the six around the world where the company researches things like computer pictures, 3D technology and, I can only imagine, how to absorb money out of your pocket at most when you vi
22、sit Disneyworld. What does physical face cloning involve? Researchers used video cameras to catch several expressions on a subjects face, recreating them in 3D computer models down to individual wrinkles and facial hair.They then experimented with different thicknesses of silicone (硅树脂) for each par
23、t of the face until they could create an example for the perfect synthetic (合成的) skin. They put that silicone skin on a 3Dprinted model of the subjects head to create their very own replica. As the authors of the study point out, its not all that different from creating a 3D model for a Pixar movie,
24、 except that in real life you have to worry about things like materials and the motors that make the face change expressions. The plan is to develop a complete process for making the physical reproduction (复制品) of a human face on animatronics equipment, meaning all youll have to do in the future is
25、record a persons face and the computer will do the rest. This is a different process than the one used to make the famous Geminoid robots from Osaka University, whose skin is individually made by artists through experiments and mistakes. In order to give the researchers more degrees of freedom in co
26、pying facial expressions, the next step is to develop more advanced equipment and multilayered synthetic skin. That means next time you go on the Pirates of the Caribbean ride, dont be surprised to see a terrifyingly realistic Johnny Deppbot playing with an appropriately deadeyed Orlando Bloom.语篇解读：
27、本文主要介绍了当今克隆面部表情的一些信息。7According to the passage, Disneys laboratory researchers are able to _.Aclone people freelyBcreate the real animalsCdevelop computer technologyDmake visitors spend more money解析：选D推理判断题。根据第一段中的“.I can only imagine, how to absorb money out of your pocket at most when you visit Di
28、sneyworld.”可知，“我”能想象到当你参观迪斯尼世界的时候，迪斯尼会从你的口袋里最大限度地捞钱。由此可推出，迪斯尼的研究者们可以让游客进入迪斯尼世界后最大限度地掏钱消费。8What equipment do researchers need to start their “face cloning”？AVideo phones and 3Dfilms.BVideo cameras and 3D computer models.C3D TVs and Video cameras.DComputers and 3D TVs.解析：选B细节理解题。根据第二段中的“Researchers us
29、ed video cameras to catch several expressions on a subjects face, recreating them in 3D computer models down to individual wrinkles and facial hair.”可知，研究人员利用摄影机来捕捉一个实验对象的几个脸部表情，然后在3D计算机模型上重新创造个体的皱纹和面部毛发。由此可知，研究人员制作面部表情需要的设备是摄影机和3D计算机模型。9What does the underlined word “replica” in Paragraph 3 mean?AA
30、 copy of the original.BA new subjects head.CA changed subjects head.DA changed silicone skin.解析：选A词义猜测题。根据第三段中的“They put that silicone skin on a 3Dprinted model of the subjects head to create their very own .”可知，他们把硅树脂做的皮肤压制在实验对象头部的3D打印模型上是为了创造他们自己的复制品。由此可猜测出画线单词的含义为“复制品”。10Whats the main idea of this passage?ASome information about face cloning.BThe process of making face cloning.CSome new information about Disney.DWhere to buy face cloning products.解析：选A主旨大意题。本文主要介绍了当今克隆面部表情的一些信息。
