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

For American's high school seniors, April is the cruelest month. That's when colleges flood postal system with news of who has won a place in next fall's freshman class. For more than a few families, a difficult decision will follow: is it worth paying some $125,000 to give their child an education at an elite private college？ Or would her future be just as bright if she went to a less expensive school？
These questions have no easy answers. It is tree that big law firms as well as those leading American establishments—Sullivan & Cromwell—a gilt-edged diploma is a distinct advantage. However, there is plenty of evidence to prove that an elite education is not that necessary. According to a survey by Fortune, the majority of top CEOs did not attend an elite college(though a small number did.)
So what kind of return is there likely to be on that $125,000 investment？ On average, a person with an undergraduate degree now earns almost twice as much as someone with only a high school diploma. Some researchers found that those who attend more prestigious schools reported higher earnings.
Then Alan Krueger, an economist at Princeton and Dale, a researcher designed a study. They found no economic advantage in attending a selective college. Their study looked at freshman class at 30 schools, ranging from Yale to Denison. Krueger and Dale's research while intriguing is not definitive. Even they themselves find it odd that the results seem to show that while there is a correlation between college selectivity and future income, the more a college costs, the higher the earning of its graduates.
Critics have questioned their research—the limited number and range of schools evaluated, and conclusions. Under such circumstances, it is hard to say which is right and which is wrong. What can be said is that 1) An elite education gives students—especially less rich ones—better access to certain kinds of elite jobs. 2) There is no economic advantage to choosing an expensive, but not very good private schools. 3) Talented students everywhere rise to the top. So the future is in the hands of young men themselves.
Why is April the cruelest month for American high school seniors？
A．Because April is the month when they have the college entrance examination.
B．Because April is the time when the high school will decide whether they can graduate or not.
C．Because April is the time for high school seniors to find jobs.
D．Because April is the month for colleges to inform. the students who will have the chance to have further education.

短文翻译(英译汉)
As a child—and as an adult as well—Bill was untidy. It has been said that in order to counteract this, Mary drew up weekly clothing plans for him. On Mondays he might go to school in blue, on Tuesdays in green, on Wednesdays in brown, on Thursdays in black, and so on Weekend meal schedules might also be planned in detail.
Bill’s contemporaries, even at the age, recognized that he was exceptional. Every year, he and his friends would go to summer camp. Bill especially liked swimming and other sports. One of his summer camp friends recalled, “He was never a nerd or a goof or the kind of kid you didn’t want your team. We all knew Bill was smarter than us. Even back then, when he was nine or ten years old, he talked like an adult and could express himself in ways that none of us understood.” Bill was also well ahead of his classmates in mathematics and science. He needed to go to a school that challenged him to Lakeside—an all-boys’ school for exceptional students. It was Seattle’s most exclusive school and was noted for its rigorous academic demands.” Lakeside allowed students to pursue their own interests, to whatever extent they wished. The school prided itself on making conditions and facilities available that would enable all its students to reach their full potential. It was the ideal environment for someone like Bill Gates.
