【正文】 out on the pillow. Did she have the nerve to move it? No, not quite. Fuming, she started to unpack. Sweaters, Tshirts, jeans, shorts and a dress. She yanked open the wardrobe door. A row of eyecatching outfits hung neatly on hangers. It39。s like a fashion store, Susan muttered, shoving the hangers aside to make space for her own clothes. In the bathroom she opened the mirrorfronted cabi on the wall. It was crammed with bottles and jars. Perfume, shampoo, creams ... Susan slammed the cabi shut and pulled a face in the glass. Meanwhile Gary was trying to make friends with Norman. Hard work. Norman proved to be a very serious young man, much given to using long words. Must39。ve swallowed a dictionary, Gary thought. But he kept up the conversation. Then the studious teenager produced a pack of cards and proceeded to do a series of conjuring tricks that made Glly could almost smell his breathmustard gas and roses. It was a wrong number. Billy hung up. There was a soft drink bottle on the windowsill. Its label boasted that it contained no nourishment whatsoever. The American fliers turned in their uniforms, became high school kids. And Hitler turned into a baby, Billy Pilgrim supposed. That wasn39。t in the movie. Billy was extrapolating. Everybody turned into a baby, and all humanity, without exception, conspired biologically to produce two perfect people named Adam and Eve, he supposed. Billy saw the war movies backwards then forwardsand then it was time to go out into his backyard to meet the flying saucer. Out he went, his blue and ivory feet crushing the wet salad of the lawn. He stopped, took a swig, of the dead champagne. It was like 7Up. He would not raise his eyes to the sky, though he knew there was a flying saucer from Tralfamadore up there. He would see it soon enough, inside and out, and he would see, too, where it came from soon enoughsoon enough. Overhead he heard the cry of what might have been a melodious owl, but it wasn39。t a melodious owl. It was a flying saucer from Tralfamadore, navigating in both space and time, therefore seeming to Billy Pilgrim to have e from nowhere all at once. Somewhere a big dog barked. The saucer was one hundred feet in diameter, with portholes around its rim. The light from the portholes was a pulsing purple. The only noise it made was the owl song. It came down to hover over Billy, and to enclose him in a cylinder of pulsing in purple light. Now there was the sound of a seeming kiss as an airtight hatch in the bottom of the saucer was opened. Down snaked a ladder that was outlined in pretty lights like a Ferris wheel. Billy39。s will was paralyzed by a zap gun aimed at him from one of the portholes. It became imperative that he take hold of the bottom rung of the sinuous ladder, which he did. The rung was electrified, so that Billy39。s hands locked onto it hard. He was hauled into the airlock, and machinery closed the bottom door. Only then did the ladder, wound onto a reel in the airlock, let him go. Only then did Billy39。s brain start working again. There were two peepholes inside the airlockwith yellow eyes pressed to them. There was a speaker on the wall. The Tralfamadorians had no voice boxes. They municated telepathicary. They were able to talk to Billy by means of a puter and a sort of electric an which made every Earthling speech sound. 39。Wele aboard, Mr. Pilgrim,39。 said the loudspeaker. 39。Any questions?39。 Billy licked his lips, thought a while, inquired at last: 39。Why me? 39。 That is a very Earthling question to ask, Mr. Pilgrim. Why you? Why us for that matter? Why anything? Because this moment simply is. Have you ever seen bugs trapped in amber?39。 39。Yes.39。 Billy in fact, had a paperweight in his office which was a blob of polished amber with three ladybugs embedded in it. 第 26 頁 共 24 頁 39。Well, here we are, Mr. Pilgrim, trapped in the amber of this moment. There is no why.39。 They introduced an anesthetic into Billy39。s atmosphere now, put him to sleep. They carded him to a cabin where he was strapped to a yellow BarcaLounger which they had stolen from a Sears amp。 Roebuck warehouse. The hold of the saucer was crammed with other stolen merchandise, which would be used to furnish Billy39。s artificial habitat in a zoo on Tralfamadore. The terrific acceleration of the saucer as it left Earth twisted Billy39。s slumbering body, distorted his face, dislodged him m time, sent him back to the war. When he regained consciousness, he wasn39。t on the flying saucer. He was in a boxcar crossing Germany again. Some people were rising from the floor of the car, and others were lying down. Billy planned to He down, too. It would be lov ely to sleep. It was black in the car, and black outside the car, which seemed to be about two miles an hour. The car never seemed to go any faster than that. It was a long time between clicks, between joints in the track. There would be a click, and then a year would go by, and then there would be another click The train often stopped to let really important trains bawl and hurtle by. Another thing it did was stop on sidings near prisons, leaving a few cars there. It was creeping across all of Germany, growing shorter all the time. And Billy let himself down oh so gradually now, hanging onto the diagonal crossbrace in the er in order to make himself seem nearly weightless to those he was joining on the floor. He knew it was important that he made himself nearly ghostlike when lying down. He had fotten why, but a reminder soon came. 39。Pilgrim,39。 said a person he was about to nestle with, 39。is that you?39。 Billy didn39。t say anything, but nestled very politely, closed his eyes. 39。God damn it39。 said the person. 39。That is you, isn39。t it?39。 He
