There are only two animals that have larger brains than man, the whale and the elephant. Yet, in proportion to his size, man's brain is larger. (19[C])Man's usually weighs about three pounds or a little more, and this is about one-fortieth of the weight of his whole body. The whale's body, on the other hand, is a thousand times heavier than its brain, while the elephant's body is about five hundred times as heavy. But a man who has a large brain is not necessarily more intelligent than one whose brain is smaller. We know that geniuses have existed who have had very large brains, but there have been others whose brains were rather small. Idiots have been known to have very large brains. (20[D])We do not understand precisely why some people are more intelligent than others. Whether our brains are relatively large or small is less important than that we try to do our very best. This article is mainly about ______. A．the weight of a whale's brain B．the brains of geniuses C．the size of a person's brain and his intelligence D．the intelligence of the elephant

A．what；that B．that；that C．what；what D．that；what

When it comes to success, luck can mean being in the right place to meet someone, or having the right skills to get a job done. It might mean turning down an offer and then having a better offer come along. Nothing can replace hard work, but working hard also means you're preparing yourself opportunity. Opportunity very often depends on luck. How many of the great inventions and discoveries came about through a lucky mistake or a lucky chance？ One of the biggest lucky mistakes in history is Columbus' so-called discovery of America. He enriched his sponsors and changed history, but he was really looking for India. However, Columbus' chance discovery wasn't pure luck. It was backed up by years of studying and calculating. He worked hard to prove his theory that the world was round. People who work hard help make their own luck by being ready opportunity knocks. When it comes to success, hard work and luck are always hand in hand. (30) A．Hard work is the most important thing for one's success. B．Hard work may invite good luck. C．Good luck plays an important role in one's success. D．Success has nothing to do with luck.

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

Blatter, a geek of dispensing FIFA's hundreds of million in annual revenue to inspire loyalty, even stands a good chance of reelection. At least he did. Since mid-March, he has seen a credible challenger emerge in Issa Hayatou, president of the African Football Confederation. Hayatou, a 55-year-old from Cameroon, leads a group of FIFA reformers that also includes FIFA Vice-President Lennart Johansson, a Swede who lost the presidential election to Blatter in 1998. These contenders' mission: to end what they call the culture of secrecy and lack of accountability that threatens FIFA with financial disaster. Representatives of the world's 204 national soccer associations meet in Seoul on May 29, and the rebels are given a chance of unseating Blatter. But even they concede that the FIFA honcho won't be easy to dislodge. Blatter's staying power seems incredible, given the array of misdeeds attributed to him and his circle. However, there are signs that FI FA's troubles are bigger than Blatter is saying. The insurgents have already won one victory: They persuaded the rest of the executive board to order an audit of FIFA finances. But Blatter—who claims, through a spokesman, that the accusations are a smear campaign—should not be underestimated. At least publicly, sponsors and member associations remain remarkably silent with the controversy. For example, there is no outward sign of outrage from German sports equipment maker Adidas-Salomon, which is spending much of its $625 million marketing budget on the World Cup. "We don't expect current developments within FIFA to have a negative impact on our expectations" for the World Cup, says Michael Riehl, Adidas head of global sports marketing. The conventional wisdom is that fans don't care about FIFA politics. Says Bernd Schiphorst, president of Hertha BSC Berlin, a top-ranked German team: "I've no fear that all these discussions are going to touch the event. "Still, the Olympic bribery scandals and the doping affair in the Tour de France show that sleazy dealings can stain the most venerable athletic spectacle. "For the Good of the Game" is FIFA's official motto. The next few months should show whether it rings true. The writer's attitude toward FIFA President Blatter seems to be that of A．slight support. B．high appreciation. C．strong contempt. D．reserved consent.

A．the risk for heart disease is definitely increasing B．there are links between depression and heart disease C．the high risk for heart disease can hardly be explained D．the reasons for higher risk of heart disease are obscure

The primary intent of his writing, from first to last, was to seize and project for the reader what he often called "the way it .was." This is a characteristically simple phrase for a concept of extraordinary complexity, and Hemingway's conception of its meaning subtly changed several times in the course of his career--always in the direction of greater complexity. At the core of the concept, however, one can invariably discern the operation of three aesthetic instruments; the sense of place the sense of fact and the sense of scene. The first of these, obviously a strong passion with Hemingway is the sense of place. "Unless you have geography, background," he once told George Anteil, "You have nothing." You have, that is to say, a dramatic vacuum. Few writers have been more place-conscious. Few have s carefully charted out she geographical ground work of their novels while managing to keep background so conspicuously unobtrusive. Few, accordingly, have been able to record more economically and graphically the way it is when you walk through the streets of Paris in search of breakfast at corner café… Or when, at around six o' clock of a Spanish dawn, you watch the bulls running from the corrals at the Puerta Rochapea through the streets of Pamplona towards the bullring. "When I woke it was the sound of the rocket exploding that announced the release of the bulls from the corrals at the edge of town. Down below the narrow street was empty. All the balconies were crowded with people. Suddenly a crowd came down the street. They were all running, packed close together. They passed along and up street toward the bullring and behind them came more men running faster, and then some stragglers who ere really running. Behind them was a little bare space, and then the bulls, galloping, tossing their heads up and down. It all went out of sight around the corner. One man fell, rolled to the gutter, and lay quiet. But the bulls went right on and did not notice him. They were all running together." This landscape is as morning-fresh as a design in India ink on clean white paper. First is the bare white street, seem from above, quiet and empty. Then one sees the first packed clot of runners. Behind these are the thinner ranks of those who move faster because they are closer to bulls. Then the almost comic stragglers, who are "really running." Brilliantly behind these shines the "little bare space," a desperate margin for error. Then the clot of running bulls-closing the design, except of course for the man in the gutter making himself, like the designer's initials, as inconspicuous as possible. According to the author, Hemingway's primary purpose in telling a story was ______. A．to construct a well-told story that the reader would thoroughly enjoy. B．To construct a story that would reflect truths that were not particular to a specific historical period C．To begin from reality but to allow his imagination to roam from "the way it was" to "the way it might have been" D．To report faithfully reality as Hemingway had experienced it.
