Questions 56 to 60 are based on the following passage.
3D glasses help doctors perform invasive surgery when their hands are obscured fromview.
Moviegoers aren't the only ones wearing 3D glasses nowadays—doctors could benefit fromthem, too, a new study suggests.
In the past, doctors have been skeptical of using 3D technology in their work, preferring torely on their own experience. But that may change, thanks to improved 3D glasses and evenglasses-free systems .Funded by industry sponsors, the study of 50 surgeons using the newtechnology showed improvements in surgical precision and speed.
"While the technology still requires some free-tuning, technology without the need to wearspecial glasses will increase the popularity of 3D systems in operating rooms," study leaderUlrich Leiner of the Fratmhofer Heinrich Hertz Institute (HHI) in Berlin said in a statement.
Improvements to screens are driving developments in 3D technology. High-definitionscreens are already available. The next step is ultra-high definition, with a sixteen foldimprovement in resolution, according to study co-author Michael Witte of HHI.
To evaluate whether new 3D technology was ready for hospital applications, researchersinvited surgeons from the Klinikum rechts der Isar's surgical hospital to test it out. A leadingendoscope manufacturer and an international display company funded the study.
The surgeons tested four different systems: 2D, 3D with glasses, 3D without glasses and amirror-based 3D system. The glasses-free model relied on an eye-tracking camera system thatdelivered separate images to each eye, creating a 3D effect in the brain.
The images came from endoscopic cameras used in surgery. The doctors practiced asimulated, routine surgical procedure in which they sewed up a wound in a model patient'sstomach using a needle and thread. Just as in a minimally invasive surgery, their hands wereobscured from view and they relied
on the screen to see what they were doing.
"The results were astonishing," Hubertus Feuner, of the Klinikum rechts der Isar universityhospital in Munich, said in a statement. The winning surgeon performed the procedure in 15percent less time and with considerably increased precision, Feuner said.
The most surprising thing was that not only young surgeons benefited, but experiencedsurgeons also, according to the researchers. The winning doctor has worked at the hospital formore than 30 years and has conducted thousands of operations.
The surgeons in the study rated the 3D glasses system the highest, and the glasses-freesystem as comparable to the 2D one.
Once the technology is widely available, will doctors begin using it. "There's no doubt that3D will be a commodity in the future." Witte said.
The study's findings will be presented at a congress of the Association of German.Surgeons in Berlin in April. The findings have not been published in a scientific peer-reviewedjournal.56. What can be inferred about 3D glasses from the second paragraph?
A) Doctors usually have a poor eye sight.
B) Moviegoers often wear 3D glasses to watch films.
C) Some doctors are moviegoers.
D) Moviegoers know how to perform surgery.
57. What was the doctors' attitude toward 3D technology in the past?
A) Apathetic.
B) Positive.
C) Disappointed.
D) Doubtful.
58. To create a 3D effect in the brain, an eye-tracking camera system
A) enabled each eye to receive separate images
B) separated images for each eye
C) delivered images of each eye through a camera
D) delivered to each glass separate images
59. The benefits that 3D technology may bring to surgeons are
A) less precision and less time
B) improved precision and less time
C) improved precision and more time
D) obscured views
60. What can be inferred from the feedbacks of the surgeons?
A) 3D glasses system has the highest technology.
B) 3D glasses system is no better than 2D one.
C) The glasses-free system is superior to the 2D one.
D) 3D glasses system is more helpful than the glasses-free system.
参考答案:
56.B)。本题考查读者对该段言外之意的理解。定位段指出,如今戴着3D眼镜的并非只有电影爱好者,一项新的研究表明3D眼镜也能让医生获益,言外之意就是,电影爱好者经常戴着3D眼镜观看电影,故答案为B)。A)“医生视力不好”、C)“有些医生也是电影爱好者”和D)“电影爱好者会做手术”在文中并未提及,故均排除。
57.D)。本题考查过去医生对3D技术的态度。定位句提到,在过去,医生对工作中使用3D技术持怀疑态度,他们更愿意依靠自身的经验,D)为skeptical的近义词,故为答案。A)“冷漠的”、B)“积极的”和C)“失望的”,均排除。
58.A)。本题考查视线捕捉摄像系统的功能。定位句提到,无需佩戴眼镜的系统依靠捕捉视线的摄像系统将独立的图像发送到每只眼睛,从而在大脑中形成3D效果,故A)为答案。B)“为眼睛分开图像”文章并未提及,故排除;C)“通过摄像机来传输眼睛的图像”是对文章意思的曲解,故排除;D)“将独立的图像发送到每个眼镜”与文意不符,故排除。
59.B)。本题考查3D技术带来的好处。由定位句可知,费斯纳尔说,“测试中完成最好的医师不仅少花了15%的时间而且精准性得到大幅提高,即更高的精准性与更少的时间”,故答案为B)。同时,排除A)与C);D)“模糊的视线”文中并未提及,故排除。
60.D)。由定位句可知,研究项目的外科医生们给3D眼镜系统的分数最高,而无需佩戴眼镜的3D系统和2D系统差不多,D)是对原文的转述,故为答案。A)“3D眼镜系统技术含量最高”在文中并未提及,故排除;B)“3D眼镜系统不比2D系统好”和C)“无需佩戴眼镜的3D系统比2D系统好”与原文逻辑不符,故均挑除。
