"A writer's job is to tell the truth," said Hemingway in 1942. No other writer of our time had so fiercely asserted, so pugnaciously defended or so consistently exemplified the writer's obligation to speak truly His standard of truth-telling remained, moreover, so high and so rigorous that he was ordinarily unwilling to admit secondary evidence, whether literary evidence or evidence picked up from other sources than his own experience. "I only know what I have seen," was a statement which came often to his lips and pen. What he had personally done, or what he knew unforgettably by having gone through one version of it, was what he was interested in telling about. This is not to say that he refused to invent freely. But he always made it a sacrosanct point to invent in terms of what he actually knew from having been there.
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.

Pepys and his wife Jane had asked some friends to dinner on Sunday, September 2nd, 1666.They were up very late on the Saturday evening, getting everything ready for the next day, and while they were busy they saw the glow(微弱的光) of a fire start in the sky. By 3 o'clock on the Sunday morning, its glow had become so bright that Jane woke her husband to watch it. Pepys slipped on his dressing-gown and went to the window to watch it. It seemed fairly far away, and after a time he went back to bed. When he got up in the morning, it looked, though the fire was dying down, as though he could still see some flames. So he set to work to tidy his room and put his things back where he wanted them.
While he was doing this, Jane came in to say that she had heard the fire was a bad one; hundreds of houses had been burned down in the night and the fire was still burning. Pepys went out to see for himself. He went to the Tower of London and climbed upon a high part of the building so that he could see what was happening. From there, Pepys could see that it was, indeed, a bad fire and that even the houses on London Bridge were burning. The man of the Tower told him that the fire had started in a baker's.shop in Pudding Lane(小巷) ; the baker's house had caught fire from the over-heated oven(烤箱) and then the flames had quickly spread to the other houses in the narrow lane. So the Great Fire of London, a fire that lasted nearly five days, destroyed most of the old city and ended, as it is said, at Pie Comer.
What is the passage about？
A．The Great Fire of London.
B．Who was the first to discover the fire.
C．What Pepys was doing during the fire.
D．The losses caused by the fire.

The next time the men were taken up onto the deck, Kunta made a point of looking at the man behind him in line, the one who lay beside him to the left when they were below. He was a Serer tribesman much older than Kunta, and his body, front and back, was creased with whip cuts, some of them so deep and festering that Kunta, felt badly for having wished sometimes that he might strike the man in the darkness for moaning se steadily in his pain. Staring back at Kunta, the Serer's dark eyes were full of fury and defiance. A whip lashed out even as they stood looking at each other—this time at Kunta, spurring him to move ahead. Trying to roll away, Kunta was kicked heavily in his ribs. But somehow he and the gasping Wolof managed to stagger back up among the other men from their shelf who were shambling toward their dousing with bucked of seawater.
A moment later, the stinging saltiness of it was burning in Kunta's wounds, and his screams joined those of others over the sound of the drum and the wheezing thing that had again begun marking time for the chained men to jump and dance for the toubob. Kunta and the Wolof were so weak from their new beating that twice they stumbled, but whip blows and kicks sent them hem hopping clumsily up and down in their chains. So great was his fury that Kunta was barely aware of the women singing "Toubob fa!" And when he had finally been chained hack down in his place in the dark hold, his heart throbbed with a lust to murder toubob.
Every few days the eight naked toubob would again come into the stinking darkness and scrape their tubs full of the excrement that had accumulated on the shelves where the chained men lay. Kunta would lie still with his eyes staring balefully in hatred, following the bobbing orange lights, listening to the toubob cursing and sometimes slipping and tailing into the slickness underfoot—so plentiful now, because of the increasing looseness of the men's bowels, that the filth had begun to drop off the edges of the shelves down into the aisleway.
The last time they were on deck, Kunta had noticed a man limping on a badly infected leg. This time the man was kept up on deck when the rest were taken back below. A few days later, the women told the other prisoners in their singing that the man's leg had been cut off and that one of the women had been brought to tend him, but that the man had died that ,fight and been thrown over the side. Starting then, when the toubob came to clean the shelves, they also dropped red-hot pieces of metal into pails of strong vinegar. The clouds of acrid steam left the hold smelling better, but soon it would again be overwhelmed by the choking stink. It was a smell that Kunta felt would never leave his lungs and skin.
The steady murmuring that went on in the hold whenever the toubob were gone kept growing in volume and intensity as the men began to communicate better and better with one another. Words not understood were whispered from mouth to ear along the shelves until someone who knew more then one tongue would send back their meaning. In the process, all of the men along each shelf learned new words in tongues they had not spoken before. Sometimes men jerked upward, bumping their heads, in the double excitement of communicating with each other and the fact that it was being done without the toubeb's knowledge. Muttering among themselves for hours, the men developed a deepening sense of intrigue and of brotherhood. Though they were of different villages and tribes, the feeling grew that they were not from different peoples or places.
