The fairest woman in the world was Helen.
So matters stood when Paris gave the golden apple to Aphrodite. The Goddess of Love and Beauty knew very well where the most beautiful woman on earth was
Menelaus returned to find Helen gone, and he called upon all of Greece to help recover her. The chieftains responded
Army had arrived, the King was plowing a field and sowing it with salt
Achilles was kept back by his mother. She sent him to the court of Lycomedes and made him wear women’s clothing, hiding him among the maidens. Odysseus was dispatched by the chieftains to bring him out. Disguised as a peddler he went to the court
So the great fleet made ready.
2 . When you ask people to judge others by their speech, a trend emerges: Listeners dislike disfluency. Slow talkers producing loads of ums and pauses(停顿)are generally perceived as less charming. But science tells us there may be even more to disfluency.
Disfluencies do not occur in arbitrary positions in sentences. Ums typically occur right before more difficult or low-frequency words. Imagine you’re having dinner with a friend at a restaurant,and there’re three items on the table: a knife, a glass, and a wine decanter(醒酒器). Your friend turns to you and says, “Could you hand me the...um...” What would you assume they want? Since it’s unlikely that they will hesitate before such common words as knife, and glass, chances are you’ll pick up the decanter and ask, “You mean this?”
This is exactly what we demonstrated through controlled eye-tracking studies in our lab. Apparently, listeners hear the um and predict that an uncommon word is most likely to follow.Such predictions, though, reflect more than just simple association between disfluencies and difficult words; listeners are actively considering from the speaker’s point of view. For example, when hearing a non-native speaker say the same sentence but with a thick foreign accent, listeners don’t show a preference for looking at low-frequency objects. This is probably because listeners assume non-native speakers may have as much trouble coming up with the English word for a common object, like a knife, as for unusual ones and can’t guess their intention.
In another experiment, listeners were presented with an atypical speaker who produced disfluencies before simple words and never before difficult words. Initially, participants displayed the natural predictive strategy: looking at uncommon objects. However, as more time went by, and they gained experience with this atypical distribution of disfluencies, listeners started to demonstrate the contrary predictive behavior: They tended to look at simple objects when hearing the speaker say um.
These findings represent further evidence that the human brain is a prediction machine: We continuously try to predict what will happen next, even though not all disfluencies are created equal.

3 . In 1953, when visiting his daughter’s maths class, the Harvard psychologist B.F. Skinner found every pupil learning the same topic in the same way at the same speed. Later, he built his first “teaching machine”, which let children tackle questions at their own pace. Since then, education technology (edtech) has repeated the cycle of hype and flop (炒作和失败), even as computers have reshaped almost every other part of life.
Softwares to “personalize” learning can help hundreds of millions of children stuck in miserable classes—but only if edtech supporters can resist the temptation to revive harmful ideas about how children learn. Alternatives have so far failed to teach so many children as efficiently as the conventional model of schooling, where classrooms, hierarchical year-groups, standardized curriculums and fixed timetables are still the typical pattern for most of the world’s nearly 1.5 billion schoolchildren. Under this pattern, too many do not reach their potential. That condition remained almost unchanged over the past 15 years, though billions have been spent on IT in schools during that period.
What really matters then? The answer is how edtech is used. One way it can help is through tailor-made instruction. Reformers think edtech can put individual attention within reach of all pupils. The other way edtech can aid learning is by making schools more productive. In California schools, instead of textbooks, pupils have “playlists”, which they use to access online lessons and take tests. The software assesses children’s progress, lightening teachers’ marking load and allowing them to focus on other tasks. A study suggested that children in early adopters of this model score better in tests than their peers at other schools.
Such innovation is welcome. But making the best of edtech means getting several things right. First, “personalized learning” must follow the evidence on how children learn. It must not be an excuse to revive pseudoscientific ideas such as “learning styles”: the theory that each child has a particular way of taking in information. This theory gave rise to government-sponsored schemes like Brain Gym, which claimed that some pupils should stretch or bend while doing sums. A less consequential falsehood is that technology means children do not need to learn facts or learn from a teacher—instead they can just use Google. Some educationalists go further, arguing that facts get in the way of skills such as creativity. Actually, the opposite is true. According to studies, most effective ways of boosting learning nearly all relied on the craft of a teacher.
Second, edtech must narrow, rather than widen, inequalities in education. Here there are grounds for optimism. Some of the pioneering schools are private ones in Silicon Valley. But many more are run by charter-school groups teaching mostly poor pupils, where laggards (成绩落后者) make the most progress relative to their peers in normal classes. A similar pattern can be observed outside America.
Third, the potential for edtech will be realized only if teachers embrace it. They are right to ask for evidence that products work. But skepticism should not turn into irrational opposition. Given what edtech promises today, closed-mindedness has no place in the classroom.

4 . “A writer’s job is to tell the truth,” said Hemingway in 1942. No other writer of our time had so fiercely stated, or so consistently (一贯地) illustrated the writer’s duty to speak truly. His standard of truth-telling remained, moreover, so high and so strict 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.
The primary intention 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 concept of its meaning subtly (微妙地) 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 recognize the operation of three instruments of beauty appreciation: 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 Antheil, “you have nothing.” You have, that is to say, a dramatic vacuum. Few writers have been more place-conscious. Few have so carefully charted out the geographical ground work of their novels while managing to keep background so unnoticeable. Few, accordingly, have been able to record more economically and graphically the way it is when you watch the bulls running through the streets of Pamplona, Spain towards the bull-ring.
“When I woke it was the sound of the rocket exploding that announced the release of the bulls. 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 the street toward the bull-ring and behind them came more men running faster, and then some stragglers (落后者) who were really running. Behind them was a little bare space, and then the bulls tossing their heads up and down. It all went out of sight around the corner. One man fell, rolled to the gutter (排水沟), and lay quiet. But the bulls went right on and did not notice him. They were all running together.”
1. What’s the main idea of the first two paragraphs?| A．Hemingway’s writing began from reality and then he would let his mind wander. |
| B．Hemingway’s primary purpose in writing was to report faithfully reality as he experienced it. |
| C．Hemingway’s writing reflects his preference for a simple story that the reader would thoroughly enjoy. |
| D．Hemingway would construct a story that would reflect truths that were not particular to a specific historical period. |
| A．Stories that he had experienced rather than read about. |
| B．Stories that he had read about in newspapers or other sources. |
| C．Stories that he had heard from friends or chance acquaintances. |
| D．Stories that came to him in periods of deep thinking or in dreams. |
| A．it shows how Hemingway understated complex issues in his books. |
| B．it reflects Hemingway’s talent for making ordinary events difficult to understand. |

| A．To vividly illustrate how exciting the bull run is. |
| B．To demonstrate that all kinds of runners can take part in the bull run. |
| C．To show Hemingway’s delicate description of the background of the bull run. |
| D．To place greater emphasis on the importance of geography, economically speaking. |
5 . The history of microbiology begins with Dutch cloth maker named Antoni van Leeuwenhoek, a man of no formal scientific education. In the late 1600s. Leeuwenhoek, inspired by the magnifying lenses（放大镜）he used to examine cloth, built some of the first-microscopes. He developed technique to improve the quality of tiny, rounded lenses, some of which could magnify an object up to 270 times. After removing some plaque from between his teeth and examining it under a lens, Leeuwenhoek found tiny twisting creatures, which he called “animalcules”.
His observations, which he reported to the Royal Society of London, are among the first descriptions of microbes（微生物）. Leeuwenhoek discovered an entire universe invisible to the human eye. He found different microbes in samples of pond water, rain water, and human blood. He gave the first description of red blood cells, observed plant tissue, examined muscle, and investigated the life cycle of insects.
Nearly two hundred years later, Leeuwenhock’s discovery of microbes helped French chemist and biologist Louis Pasteur to develop his “theory of disease”. This concept suggested that disease originates from tiny organisms attacking and weakening the body. Pasteur’s theory later helped doctors to fight infectious diseases including anthrax, diphtheria, polio, smallpox, tetanus, and typhoid. All these breakthroughs were the result of Leeuwenhoek’s original work. Leeuwenhoek did not foresee this legacy.
In a 1716 letter, he described his contribution to science this way: “My work, which I’ve done for a long time, was not pursued in order to gain the praise I now enjoy, but chiefly from a strong desire for knowledge, which I notice resides in me more than in most other men. And therefore; whenever I found out anything remarkable, I have thought it my duty to put down my discovery on paper, so that the scientific community might be informed thereof.”

7 . Why make a film about Ned Kelly? More ingenious crime than those committed by the reckless Australian bandit are reported every day. What is there in Ned Kelly to justify dragging the mesmeric Mick Jagger so far into the Australian bush and away from his natural haunts? The answer is that the film makers know we always fall for a bandit, and Jagger is set to do for bold Ned Kelly what Brando once did for the arrogant Emiliano Zapata.
The bandit inhabits a special realm of legend where his deeds are embroidered by others; where his death rather than his life is considered beyond belief; where the men who bring him to“justice” are afflicted with doubts about their role.
The bandits had a role to play as definite as that of the authorities who condemned them. These were men in conflict with authority, and, in the absence of strong law or the idea of loyal opposition, they took to the hills. Even there, however, many of them obeyed certain unwritten rules.
There robbers, who claimed to be something more than mere thieves, had in common, firstly, a sense of loyalty and identity with the peasants they came from. They didn’t steal the peasant’s harvest; they did steal the lord’s.
And certain characteristics seem to apply to “social bandits” whether they were in Sicily or Peru. They were generally young men under the age of marriage, predictably the best age for dissidence. Some were simply the surplus male population who had to look for another source of income; others were runway serfs or ex-soldiers; a minority, though the most interesting, were outstanding men who were unwilling to accept the meek and passive role of peasant.
They usually operated in bands between ten and twenty strong and relied for survival on difficult terrain and bad transport. And bandits proposed best where authority was merely local —over the next hill and they were free. Unlike the general run of peasantry they had a taste for flamboyant dress and gesture; but they usually shared the peasants’ religious beliefs and superstitions.
The first sign of a man caught up in the Robin Hood syndrome was when he started out, forced into outlawry as a victim of injustice; and when he then set out to “right wrongs”, first his own and then other people’s. The classic bandit then “take from the rich and gives to the poor” in conformity with his own sense of social justice; he never kills except in self-defense or justifiable place; his people admire and help to protect him; he dies through the treason of one of them; he behaves as of invisible and invulnerable; he is a “loyalist”, never the enemy of the king but only of the local oppressors.
None of the bandits lived up fully to this image of the “noble robber” and for many the claim of larger motives was often a delusion.
Yet amazingly, many of these violent men did behave at least half the time in accordance with this idealist pattern. Pancho Villa in Mexico and Salvatore Giuliano in Italy began their careers harshly victimized. Many of their charitable acts later became legends.
The bandit in the real world is rooted in peasant society and when its simple agricultural system is left behind so is he. But the tales and legends, the books and films continue to appear for an audience that is neither peasant nor bandit. In some ways the characters and deeds of the great bandits could so readily be the stuff of grand opera — Don Jose on “Carmen” is based on the Andalusian bandit El Empranillo. But they are perhaps more at home in folk songs, in popular tales and the ritual dramas of films. When we sit in the darkness of the cinema to watch the bold deeds of Ned Kelly we are caught up in admiration for their strong individuality, their simple gesture of protest, their passion for justice and their confidence that they cannot be beaten. This sustains us nearly as much as it did the almost hopeless people from whom they sprang.

| B．Claimed (Para. 4). |
| C．Legend (Para. 2). |
| D．Loyalty (Para. 4). |

I’m smaller than everyone else my age. When I walk in the halls at school, I have to squeeze in between the bigger kids to get by. At the playground, sometimes even little kids try to boss me around. Mia, my best friend, is so tall that when she walks, I have to jog to keep up with her.
I used to try to make myself taller whenever I could. My posture was perfect, straight as an arrow. I hung from the tree in our backyard to stretch out my arms and legs. I even ate all my vegetables. Every day I measured myself, but I was the same height every time. Frustrating!
“Don’t worry,” Mom always said. “Being small has its advantages.” “Really? I could never notice any.”
One day, Mrs. Alvarez announced to the class that we’d be putting on a spring play. I practiced all the lines. But at the audition (试演), when I walked up to the stage, Mrs. Alvarez cried, “You’ll be perfect as the elf (小精灵)! You’re just the right size for the costume.” I even never got a chance to deliver the practiced lines. Back home I grumbled (咕哝) to mum that I was made an elf. But she bet I would be the best elf. To please her, I went to rehearsals (排练), though I only had two lines.
Mia got the lead role-a girl wandering through a magical fairy forest in search of her lost dog. In the last scene, she finds a box under a giant mushroom, and when she opens it, her dog jumps out. Mrs. Alvarez’s dog, Prince, played the dog role. She brought him to all the rehearsals, and when he wasn’t onstage, we got to play with him, but he seemed to like me best.
The night of the show, my first line came early, “Let’s ask the Fairy Queen!” Since my only other line was toward the end, I waited offstage, playing with Prince.

9 . Revealing the source of Jupiter’s x-ray auroral flares
Abstract
Jupiter’s rapidly rotating, strong magnetic field provides a natural laboratory that is key to understanding the dynamics (动力学) of high-energy plasmas (等离子体). Spectacular auroral (极光的) X-ray flares (耀斑) are diagnostic of the most energetic processes governing magnetospheres but seemingly unique to Jupiter. Since their discovery 40 years ago, the processes that produce Jupiter’s X-ray flares have remained unknown. Here, we report simultaneous (同时的) in situ satellite and space-based telescope observations that reveal the processes that produce Jupiter’s X-ray flares, showing surprising similarities to terrestrial ion aurora. Planetary-scale electromagnetic waves are observed to modulate (调节) electromagnetic ion cyclotron waves, periodically causing heavy ions to precipitate and produce Jupiter’s X-ray pulses. Our findings show that ion aurorae share common mechanisms across planetary systems, despite temporal, spatial, and energetic scales varying by orders of magnitude.
INTRODUCTION
Aurorae, observed from planetary polar regions across the solar system, are displays of light that are produced when energetic particles precipitate along magnetic field lines and transfer their energy to the atmosphere. Jupiter’s soft x-ray aurorae are produced by energetic [~ (MeV) (电子伏)] heavy ions (S and O), originally from the moon Io’s (木卫一的) volcanic activities. The dynamic X-ray emissions often pulse with a regular beat of a few tens of minutes. The spectacular quasi-periodic (准周期性的) auroral pulsations at Jupiter have also been observed in ultraviolet (UV), infrared, and radio emissions. The X-ray aurorae are predominately confined (主要局限于) to the region poleward of Jupiter’s main aurora, connecting to Jupiter’s outer magnetosphere via magnetic field lines. The mapping of the emissions leads to the suggestion that the particle precipitations were driven by magnetic reconnection. However, observations show that the x-ray pulsations last for several Jupiter days or longer, evidencing that the driver may not be a transient process like magnetic reconnection.
To date, 40 years after their discovery, the mechanisms that cause these X-ray aurorae remain unknown. Simultaneous measurements of the magnetospheric environment and the auroral emissions are critical to revealing their driving mechanisms. Here, we present observations of Jupiter’s unique x-ray aurorae with simultaneous in situ measurements from the magnetosphere. In this study, we reveal the physical driver for Jupiter’s pulsating x-ray emissions by analyzing simultaneous in situ measurements from Juno and remote spectroscopic imaging by XMM-Newton telescope (XMM，牛顿卫星) during 16 and 17 July 2017. XMM’s European Photon Imaging Camera (EPIC-pn and MOS) instruments provided spatial, spectral, and timing data of Jupiter for a continuous 26-hour (~2.6 Jupiter rotations) observation from 18:26 UT on 16 July to 22:13 UT on 17 July, which was shifted to account for the ~46-min light travel time between Jupiter and Earth. This XMM observation was planned to coincide with the time when NASA’s Juno spacecraft was moving from 62 to 68 RJ (1 RJ = 71 492 km) radially away from the planet in the Southern Hemisphere in the predawn sector between ~0400 and 0430 magnetospheric local time (MLT).
Ionosphere-magnetosphere (电离层) mapping from previous observations suggested that the origins of Jupiter’s X-ray auroral pulsations occurred at these distances from the planet. Juno provided contemporaneous (同时发生的) in situ measurements from the plasma sheet only when Jupiter’s north magnetic pole tilted to Earth. Therefore, we focus on the northern aurora, for which Juno’s in situ measurements detail what was happening in the plasma sheet during the X-ray pulses. At Jupiter, the analysis of these comparisons between in situ and remote sensing observations is more complex than at Earth. At Earth, during the time scale of an auroral event, typically tens of minutes, a spacecraft in the terrestrial magnetosphere usually travels little (e.g., hundreds of kilometers) in comparison to the spatial scale of a magnetospheric event (e.g., several Earth radii) that would cause a large auroral brightening so that this in situ spacecraft could be magnetically connected to the aurora region over the full auroral lifetime. This is not true for Jupiter, because the footprint of the aurora (which is rotating with Jupiter) with respect to Juno’s location changes substantially during an observation. There are also substantial travel times (a few tens of minutes) along the magnetic field expected from the outer magnetosphere to the Jovian aurora. Therefore, the correlation between a single outer magnetosphere event in Jupiter’s in situ measurements and a single auroral pulse cannot be expected on a one-to-one level basis. Instead, a series of successive events are required to draw reliable careful correlations, with the regular periodicity of the x-ray flares, providing an invaluable diagnostic signature of the source process.

10 . If you wear glasses, chances are you are smarter. Research published in the famous British journal Nature Communications has found that people who displayed higher levels of intelligence were almost 30 percent more likely to wear glasses.
The scientists studied the genes of thousands of people between the ages of 16 and 102.The study showed intelligence can be connected to physical characteristics. One characteristic was eyesight. In out of 10 people who were more intelligent, there was a higher chance they needed glasses. Scientists also said being smarter has other benefits. It is connected to better health.
It is important to remember these are connections which are not proven causes. Scientists call this correlation. Just because something is connected to something else does not mean one of those things caused the other. And it’s worth noting that what constitutes intelligence is subjective and can be difficult, if not impossible, to measure.
Forget genes though. Plenty of proof shows wearing glasses makes people think you are more intelligent, even if you do not need glasses. A number of studies have found people who wear glasses are seen as smarter, hard-working and honest. Many lawyers use this idea to help win their cases. Lawyer Harvey Solves explained this. Glasses soften their appearance. He said Sometimes there has been a huge amount of proof showing that people he was defending broke the law. He had them wear glasses and they weren’t found guilty.
Glasses are also used to show someone is intelligent in movies and on TV. Ideas about people who wear glasses have begun to shift. People who do not need glasses sometimes wear them for fashion only. They want to look worldly or cool. But not everyone is impressed by this idea, though. GQ magazine said people who wear glasses for fashion are trying too hard to look smart and hip (时髦的). However, that hasn’t stopped many celebrities from happily wearing glasses even if they do not need them. Justin Bieber is just one high-profile fan of fashion glasses.
