Surgeons are being able to enter the eye to carry out operations——atleast in a virtual sense.
Techniques derived from virtual reality- the computer system that immerses operations in an artificial computer-generatedworld —— will allow surgeons to feel as if he could see the inside of， the eyeduring an operation， creating the illusion that they are actually there.
Researchers at the Biorobotics （生物机械人技术） Laboratory of McGill University in Montreal are building a robot， known as Micro SurgeryRobot-1 （MSR-I for short） ， that will perform. delicate operations under thecontrol of a human surgeon. The robot is specifically designed for performing eye surgery but could have other applications， such as the removal ofbrain tumors.
The system could also be used to allow surgeons and theirstudents to practice simulated surgery that feel like the real thing —— withoutthe real consequences for the patients.
During the operations， the surgeon manipulates a set of controls knownas the master. These are connected through a high-performance computer tothe robot. Both the master and the robot have two limbs. When the surgeonmoves the master"s limbs， the robot"s limbs move in exactly the same way， except that the movements can be sealed down as much as a thousandtimes. This will eliminate hand tremor and poor accuracy and thus reducethe damage to the eye that can occur with present microsurgery techniques.Each of the robot"s limbs has a minimum movement of one micrometer——more than one hundred times the precision of the human hand.
The computer also creates a three-dimensional robot"s eye view of theinside of the eye that the surgeon can see by wearing a virtual reality helmet （头盔） that has a small lens in front of each eye.
To provide the surgeon with such a realistic experience， MSR-I must beable to move rapidly，but this requires extremely fast computing. To handlethe computational demands of instant interaction， the McGill team is constructing its own parallel-processing computer. It is also studying areas such asmuscle mechanism， artificial intelligence and optics， and has already built another microrobot， MR-I， capable of manipulating a single living cell.
The so-called "virtual reality" mentioned in this passage refers to __________. 查看材料
A.operations conducted inside the eye
B.computer-created illusions that assist in operations
C.new applications of visual technology
D.new notions that help improve microsurgery
Researchers at the Biorobotics (生物机械技术)Laboratory of McGill University in Montreal are building a robot , known as Micro Surgery robot-1(MSR- I for short), that will perform. delicate operations under the control of a human surgeon.

The system could also be used to allow surgeons and their students to practise simulated surgery that feel like the real thing- without the real consequences for the patients.

Each of the robots limbs has a minimum movement of one micrometer---more than one hundred times the precision of the human hand.
The computer also creates a three - dimensional robot' s eye view of the inside of the eye that the surgeon can see by wearing a virtual reality helmet (虚拟现实头盔) that has a small lens in front of each eye.

Although commercial applications of the new system are not expected for several years, its basic mechanical components will be ready for testing in a few months, "The day when micro robots will be able to perform. surgery without human intervention is many years away," says Hunter, "in the meantime , a system such as MRS-I is a necessary precursor."
The so-called "virtual reality "mentioned in this passage is actually.
A．a surgical tool used for operations
B．a computer system used to produce life- like illusions
C．a new kind of applications in a visual technology.
D a way to carry out operations in a visual sense
2. Modern surgery stresses accurate diagnosis of the disease and proper care of the patient before and after the operation. Thus, the surgeon not only needs to know how to perform. an operation, but also must have a wide knowledge of anatomy, physiology, chemistry, and pathology. Five to eight years of training after medical school are necessary for physicians to qualify as surgeons.
3. A surgical operation is complicated. Many people, medicines, equipment, and techniques help assure the greatest possible safety and comfort for the patient. The elimination of pain, the prevention of infection, and advanced means of diagnosis are all part of modern surgery. A qualified surgical team is essential to the success of both the operation and the patient' s recovery. This team usually consists of a surgeon, at least one assistant, an anesthesiologist, and one or more nurses.
4. A surgeon uses many instruments in the course of an operation. These instruments include holders for needles and sponges, clamps to close off blood vessels, and retractors to hold back folds of skin. Sharp instruments include scissors and scalpels. Since the 1970' s, lasers have been used to make delicate cuts in body tissues. Doctors use the high- energy light of the laser to cut tissue by burning fine lines in the skin or other organs.
5. A surgeon can remove a long section of diseased intestine and sew the remaining intestinal sections together. The body will function normally after the operation. A kidney, or even a major part of the stomach, can be removed by an operation. In heart surgery, a doctor may replace one of the heart valves with an artificial one. Extensive surgery on the lungs and ribs is often part of the treatment of cancer. Sometimes an en- tire diseased lung is removed. A neurosurgeon can remove brain tumors and repair head injuries. Transplanting organs involves taking a healthy organ from one person and using it to replace the diseased organ in another person. The kidney is a commonly transplant- ed organ. The transplanted tissue must closely match that of the patient, or the patient' s body will reject the new organ.
6. In microsurgery, the surgeon operates while viewing the procedure through a microscope or magnifying glass. This technique enables physicians to perform. operations on some of the tiniest body structures. For example, surgeons can rejoin extremely small blood vessels and nerves by using this technique. Such surgery has led to the successful reattachment of severed fingers, hands, and even arms and legs. Doctors also use micro- surgery to operate on the delicate structures in the eye, the kidney, the brain, and many other parts of the body.
A. Modern techniques enable the surgeon to operate successfully upon all parts of the human body
B. Surgeons are especially trained so that they are skill- fully qualified for the performance of complicated operations
C. An entire stomach can not be removed even in modem surgery
D. The various mechanical instruments used in the course of a surgical operation
E. For a physician requires eight years of training in a medical school
F. The elimination of pain, the prevention of infection, and advanced means, of diagnosis are prerequisites to the success of an operation
Paragraph 2 ______
A Minor Microsurgery
Last year, Sean Martinovich, from Whitianga, had life-saving surgery when a golf-sized tumor was removed from his brain stem. But the operation left half his face paralysed. He talked with a slur, sometimes dribbled out of the side of his mouth and could not close his eye properly. Although he could run around with the other boys in the playground, when they laughed he could not laugh with them. Without a smile, he could suffer psychologically and emotionally.
Last week, 6-year-old Sean had seven hours of microsurgery that should give him back his smile. Doctor Bartlett removed a nerve from the back of one of Sean's legs and transplanted it into his face. On the normal side of his face the nerve divides into lots of little branches. "We'll cut those nerve branches and then we'll take a nerve graft from one leg and tunnel it across his face from one side to the other and join that on to the nerve that's been cut on the good side of his face. " Doctor Bartlett said, before the operation. "If this was not fixed he could face physical and emotional problems as he got older," Doctor Bartlett said. "Socially people can become quite withdrawn because of the face paralysis. It's easy for people, especially children, to become rather emotionless because they prefer the flatness of no movement on either side to the weirdness of an asymmetry of smiling on one side and having this twisted face. "
Scan is not smiling yet. Over the next six months the nerves will grow across the face to the damaged side and after that movement will hopefully come back. Sean's parents, Steve and Wendy Martinovich, said they had been through a year of hell. But their son was a determined boy who just got on with it, said Mrs Martinovich. They are amazed at the technology that they hope will restore the cheeky smile they love so much. For Doctor Bartlett the microsurgery is almost routine. For Sean's parents, it is a miracle.
How old was Scan Martinovich when the golf-sized tumor was removed from his brain stem？ ______.
A．4 years old.
B．5 years old.
C．6 years old.
D．7 years old.
