22、 the questions which accompany them by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1. 50 Gene therapy and gene based drugs are two ways we could benefit from our growing mastery of genetic science. But there will be others as well. Here is one of the remarkable therapies on the cutting

23、edge of genetic research that could make their way into mainstream medicine in the coming years. While its true that just about every cell in the body has the instructions to make a complete human, most of those instructions are inactivated, and with good reason: the last thing you want for your bra

24、in cells is to start churning out stomach acid or your nose to turn into a kidney. The only time cells truly have the potential to turn into any and all body parts is very early in a pregnancy, when so-called stem cells havent begun to specialize. Yet this untapped potential could be a terrific boon

25、 to medicine. Most diseases involve the death of healthy cells brain cells in Alzheimers, cardiac cells in heart disease, pancreatic cells in diabetes, to name a few; if doctors could isolate stem cells, then direct their growth, they might be able to furnish patients with healthy replacement tissue

26、. It was incredibly difficult, but last fall scientists at the University of Wisconsin managed to isolate stem cells and get them to grow into neural, gut, muscle and bone cells. The process still cant be controlled, and may have unforeseen limitations; but if efforts to understand and master stem c

27、ell development prove successful, doctors will have a therapeutic tool of incredible power. The same applies to cloning, which is really just the other side of the coin. True cloning, as first shown with the sheep Dolly two years ago, involves taking a developed cell and reactivating the genome with

28、in, resetting its developmental instructions to a pristine state. Once that happens, the rejuvenated cell can develop into a full-fledged animal, genetically identical to its parent. For agriculture, in which purely physical characteristics like milk production in a cow or low fat in a hog have real

29、 market value, biological carbon copies could become routine within a few years. This past year scientists have done for mice and cows what Ian Wilmut did for Dolly, and other creatures are bound to join the cloned menagerie in the coming year. Human cloning, on the other hand, may be technically fe

30、asible but legally and emotionally more difficult. Still, one day it will happen. The ability to reset body cells to a pristine, undeveloped state could give doctors exactly the same advantages they would get from stem cells: the potential to make healthy body tissues of all sorts, and thus to cure

31、disease. That could prove to be a true “miracle cure“. 51 The writer holds that the potential to make healthy body tissues will_. （ A） aggravate moral issues of human cloning （ B） bring great benefits to human beings （ C） help scientists decode body instructions （ D） involve employing surgical instr

32、uments 52 The word “rejuvenated“ (Para. 5) most probably means _. （ A） modified （ B） re-collected （ C） classified （ D） reactivated 53 The research at the University of Wisconsin is mentioned to show_. （ A） the isolation of stem cells （ B） the effects of gene therapies （ C） the advantages of human cl

33、oning （ D） the limitations of tissue replacements 54 Which of the following is true according to the text? （ A） The principle of gene therapy is applicable to that of cloning. （ B） The isolation of stem cells is too difficult to be feasible. （ C） It is reasonable for all body instructions to be acti

34、vated. （ D） Cloned animals will eventually take control of the world. 55 Towards the genetic research, the author s attitude can best be said to be that of_. （ A） frustration （ B） indifference （ C） amazement （ D） opposition 55 Earthquake survivors trapped in rubble could one day be saved by an unlik

35、ely rescuer: A robotic caterpillar that burrows its way through debris. Just a few centimeters wide, the robot relies on magnetic fields to propel it through the kind of tiny crevices that would foil the wheeled or tracked search robots currently used to locate people trapped in collapsed buildings.

36、 The caterpillar s inventor, Norihiko Saga of Akita Prefectural University in Japan, will demonstrate his new method of locomotion at a conference on magnetic materials in Seattle. In addition to lights and cameras, a search caterpillar could be equipped with an array of sensors to measure other fac

37、tors such as radioactivity or oxygen levels that could tell human rescuers if an area is safe to enter. The magnetic caterpillar is amazingly simple. It moves by a process similar to peristalsis, the rhythmic contraction that moves food down your intestine. Saga made the caterpillar from a series of

38、 rubber capsules filled with a magnetic fluid consisting of iron particles, water, and a detergent-like surfactant, which reduces the surface tension of the fluid. Each capsule is linked to the next by a pair of rubber rods. The caterpillars guts are wrapped in a clear, flexible polymer tube that pr

39、otects it from the environment. To make the caterpillar move forwards, Saga moves a magnetic field backwards along the caterpillar. Inside the caterpillars “head“ capsule, magnetic fluid surges towards the attractive magnetic field, causing the capsule to bulge out to the sides and draw its front an

40、d rear portions up. As the magnetic field passes to the next capsule, the first breaks free and springs forward and the next capsule bunches up. In this way, the caterpillar can reach speeds of 4 centimeters per second as it crawls along. Moving the magnetic field faster can make it traverse the cat

41、erpillar before all the capsules have sprung back to their original shapes. The segments then all spring back, almost but not quite simultaneously. Saga plans to automate the movement of the caterpillar by placing electromagnets at regular intervals along the inside of its polymer tube. By phasing t

42、he current flow to the electromagnets, hell be able to control it wirelessly via remote control. He also needs to find a new type of rubber for the magnetic capsules, because the one hes using at the minute eventually begins to leak. But crawling is not the most efficient form of locomotion for robo

43、ts, says Robert Full of the University of California at Berkeley, an expert in animal motion who occasionally advises robotics designers. “If you look at the energetic cost of crawling, compared to walking, swimming or flying, crawling is very expensive,“ he says. Walking, on the other every step, e

44、nergy is conserved in the foot and then released to help the foot spring up. Saga acknowledges this inefficiency but says his caterpillar is far more stable than one that walks, rolls on wheels or flies. It has no moving parts save for a few fluid-filled rubber capsules. Biped robots and wheeled rob

45、ots require a smooth surface and are difficult to miniaturize, and flying robots have too many moving parts. “My peristaltic crawling robot is simple and it works,“ he says. 56 From this passage, we can learn that_. （ A） a robotic caterpillar can crawl by a pair of rubber rods （ B） when a caterpilla

46、r moves, the magnetic field moves backwards along it （ C） the environment couldnt influence a robotic caterpillar s guts, which are wrapped in a capsule （ D） crawling is very stable and efficient, and when it moves, only a few elements are needed 57 According to this passage, which is not true about

47、 the construction of the robotic caterpillar? （ A） A robotic caterpillar is made from a series of rubber capsules filled with a magnetic fluid. （ B） Iron particles, water, and a detergent-like surfactant form a magnetic fluid. （ C） Each capsule filled with a magnetic fluid is linked to the next by a

48、 pair of rubber rods. （ D） In order to keep stable condition, the caterpillar s guts are wrapped in a clear, flexible polymer tube. 58 The meaning of the word “peristalsis“ in Paragraph 3 is similar to_. （ A） swimming （ B） flying （ C） crawling （ D） walking 59 Comparing the robotic caterpillar and th

49、e other robots, which of the following is not true? （ A） A smooth surface is indispensable to biped robots and wheeled robots. （ B） Flying robots are very inconvenient when moving, because they have too many moving parts. （ C） The robotic caterpillar only has rubber capsules filled with a magnetic fluid. （ D） It s incapable for wheeled robots to locate trapped people because they are impossible to miniaturize
