听力原文： Prince is a major racket goods sporting company. We make tennis, squash, badminton rackets, apparel and footwear. We also sell the accessories to those products which include strings, grips and sport bags, and other accessory products as well. Prince is headquartered in Bordentown, New Jersey, which is just a little bit south of Trenton, New Jersey, and just a little bit north of Philadelphia. We also have offices in Europe, in Treviso, Italy. We have an office in Singapore which coordinates the Asian theater for us. And then we have distributors scattered throughout the world.
In 1989 we were acquired by the Benetton Sports System. Benetton Sports System is comprised of a number of different companies but an easy illustration would be to think of an umbrella and the umbrella would be the Benetton Sports System. Underneath the umbrella would be three columns: one column would be Rollerblade, which is the in-line skating company; another column would be Nordica, which is the winter sport group; and the third column would be Prince Sports Group, which is our company, which deals with the summer sporting goods. And then they are all connected across the bottom by Benetton Sports System Active that is responsible for the apparel for all three of those groups.
Well, tennis equipment has changed considerably in the last twenty years. If we go back to before 1976, really most players were playing with wooden rackets. And you notice the wood rackets' very small head sizes. Howard Head came along and not only innovated the ski industry with the first metal ski, but innovated the tennis industry with the first dimensional change in tennis rackets. And that, essentially, means he invented the oversized head. If you compare it to a wooden racket, you can see quite clearly you've got a much larger head on the oversize racket. That happened in the mid-seventies. Then the next major innovation occurred with another dimensional change in the rackets which was the wide body. Wide bodies allowed for greater stiffness in rackets therefore producing much more power.
And today the next biggest innovation is also dimensional—and that is length. Here is our new Mach 1000. The Prince Long Body racket gives you five major benefits. They are: more power, more control, more spin, more reach and more comfort. Welt, l think this is the last dimensional change in a racket that can occur. Again, just to repeat, you had the first dimensional change which was head size—larger head size; the second dimensional change was cross-section and now we're looking at the third and final eras that you can change in terms of a racket's geometry, which is length. So ! think what you'll see over the next several years is—who can make the best longer rackets.
？You will hear a presentation about an introduction of a racket goods sporting company.
？As you listen, for questions 1—12, complete the notes, using up to three words or a number.
？You will hear the recording twice.

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
