Surgeons will soon be able to enter the eye to carry out operations—at least in a virtual sense. Techniques derived from virtual reality the computer system that immerses operations in an artificial computer-generated world—will allow surgeons to feel as if he could see the in side of the eye during an operation, creating the illusion that they are actually there.
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 robot is specifically designed for performing eye surgery but could have other applications, such as the removal of brain tumors. 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.
During the operations, the surgeon manipulates a set of control known as the master. These are connected through a high- performance computer to the robot. Both the master and the robot have two limbs, When the surgeon moves the masters' limbs, the robots limbs move in exactly the same way, except that the movements can be scaled down as much as a thousand times. This will eliminate hand tremor and poor accuracy and thus reduce the damage to the eye that can occur with present microsurgery techniques. 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.
To provide the surgeon with such a realistic experience, MSR-I must be able to move rapidly, but this requires extremely fast computing. To handle the computational demands of instant interaction, the McGill team is constructing its own parallel-processing computer., It is al so studying areas such as muscle mechanism, artificial intelligence and optics, and has a already built another micro robot MR- I, capable of manipulating a single living cell.
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

If we were asked exactly what we were doing a year ago，we should probably have to say that we could not remember. But if we had kept a book and had written in it an account of what we did each day, we should be able to give an answer to the question.
It is the same in history. Many things have been forgotten because we do not have any written account of them. Sometimes men did keep a record of the most important happenings in their country，but often it was destroyed by fire or in a war. Sometimes there was never any written record at all because the people of that time and place did not know how to write. For example, we know a good deal about the people who lived in China 4, 000 years ago, because they could write and leave written records for those who lived after them. But we know almost nothing about the people who lived even 200 years ago in central Africa because they had not learned to write.
Sometimes, of course, even if the people cannot write, they may know something of the past. They have heard about it from older people and often songs and dances and stories have been made about the most important happenings, and these have been sung and acted and told for many generations, for most people are proud to tell what their fathers did in the past. This we may call ？remembered history ” . Some of it has now been written down. It is not so exact or so valuable to us as written history is, because words are much more easily changed when used again and again in speech than when copied in writing. But if there are no written records, such spoken stories are often very helpful.
Which of the following is NOT suggested in the passage？
A.Written history is more reliable.
B.Written records play an important role in learning about history.
C.A written account of our daily activities helps to answer many questions.
D.Where there are no written records, there is no history.
Little is known about the central Africa 200 years ago because ______.A.there was nothing worth writing down at that time
B.people there ignored the importance of keeping a record
C.people there did not know how to write
D.the written records were perhaps destroyed by a fire
“ Remembered history” refers to ______.A.history based on a person’s imagination
B.stories of important happenings passed down from mouth to mouth
C.songs and dances about the most important events.
D.both B and C
“ Remembered history” is regarded as valuable only when ______.A.it is written down
B.No written account is available
C.it proves to be timely
D.People are interested in it
It is suggested that we could have learned more about our past if ancient people had ______.A.kept a written record of every past event
B.burnt their written records in wars
C.told exact stories of the most important happenings
D.made more songs and dances
