Breathe, wave and smile. Along with more than 300 other seniors, I marched into the stadium on the afternoon of May 10. The audience burst into deafening cheers. The huge stadium shook with all the whistling and clapping.
It was as if a Hollywood superstar had walked on stage. And indeed, every single senior that day was a star of the moment. Each deserved it. The seniors had been preparing for four years for this once-in-a-lifetime moment—the commencement (graduation ceremony).
Seated, I waited anxiously for the opening address. As a foreign exchange student, I was not able to receive a diploma. However, I still had the wonderful feeling of being part of things. Like the other graduates, I was dressed in marron cap and gown.
Our principal, Mr. Glover, delivered a short, warm greeting. The US national anthem followed and then, hands on chests, a solemn Pledge of Allegiance(美国的爱国誓言).
Students who had excelled academically gave farewell speeches. The tears in some eyes convinced me that many had deep feelings about the occasion. It was as the class motto says, “Life brings us tears, smiles and memories. The tears dry; the smiles fade; but the memories last forever.”
Then came the core (the most important part) of the commencement. Hundreds of names were announced. Each graduate walked across the stage to receive his or her diploma from the principal. From the different cheers each graduate got, we had the funny sense that it was a kind of competition of who could cheer the loudest.
To be honest, the presentation of diplomas got boring. A girl sitting next to me even started yawning. But it wasn’t boring for those receiving the diploma: they would treasure the moment the principal placed the sacred brown document in their hands for the rest of their lives.
A new page in the book of that person’s life had turned. They were glimpsing their futures: futures of challenge, hardship, perhaps loneliness too, which would take all of their courage.What’s the article mainly about?

Sydney—A shark savaged a schoolboy's leg while he was surfing with his father at a beach in Sydney on February 23．It was the third shark attack along the coast of Australia's largest city in a month．
The 15-year-old boy and his father were in the water off Avalon, on Sydney's northern beaches, around dawn when he was attacked．The city's beaches are packed with locals and tourists during the summer months．
"The father heard a scream and turned to see his son trashing （扭动） about in the water," police said．"Fortunately, the shark swam away and the boy was helped to shore by his father．
Lifesaving Club spokesman Nick Miller: "It got him around the top of his left leg and the father came and dragged him out of water．" He said the boy was bleeding heavily when he was brought to shore．"There was a lot of pain, as you can imagine"．The teenager was airlifted to hospital for treatment for leg injuries．
Police said the bites" cut through to the bone" , but the boy did not appear to have sustained any fractures （骨折）．He was in a stable condition now．
Several beaches were closed after the attack．Water police and lifeguards were searching for the shark, while police hoped to identify its species by the shape of the bite marks．But they said it was too early to say what type of shark attacked the boy．"I don't even know if he saw it," Miller said．
Many shark species live in the waters off Sydney's beaches, but attacks on humans are still relatively rare．However, there were two attacks on successive days earlier this month, one on a navy diver in Sydney harbor, not far from the famous Opera House, and the other on a surfer at the city's world-famous Bondi beach．
Fishermen say shark numbers are on the rise．There is a ban on commercial fishing in the harbor, which has increased fish stocks．Marine experts also claim environmental protection has created a cleaner environment, attracting sharks closer to shore as they chase fish．Many shark species, including the Great White—the man-eater made famous in Steven Spielberg's Jaws—are protected in Australian waters．The report mainly tells us _______．
| A．shark attacks on humans are on the rise |
| B．sharks attacked humans three times in one month |
| C．a boy was attacked by a shark at a Sydney beach |
| D．shark numbers are increasing in the waters off Sydney's beaches |
The underlined word" savaged "in the first paragraph probably means _______．
| A．attracted | B．dragged |
| C．bit | D．packed |

People have wondered for a long time how their personalities and behavior are formed. It is not easy to explain why one person is intelligent and another is not, or why one is cooperative and another is competitive.
Social scientists are of course extremely interested in these types of questions. They want to explain why we possess certain characteristics and exhibit certain behavior. There are no clear answers yet, but two distinct schools of thought on the matter have developed. As one might expect, the two approaches are very different from each other, and there is a great deal of debate between proponents of each theory. The controversy is often conveniently referred to as “nature and nurture”．
Those who support the “nature” side of the conflict believe that our personalities and behavior patterns are largely determined by biological factors. That our environment has little, if anything, to do with our abilities, characteristics and behavior is central to this theory. Taken to an extreme，this theory states that our behavior is predetermined to such a great degree that we are almost completely governed by our instincts(本能)．
Proponents of the “nurture” theory, or, as they are often called, behaviorists, claim that our environment is more important than our biologically based instincts in determining how we will act. A behaviorist, B. F. Skinner, sees humans as beings whose behavior is almost completely shaped by their surroundings. The behaviorists' view of the human being is quite mechanistic. They state that, like machines, humans respond to environmental stimuli (刺激) as the basis of their behavior.
Socially and politically, the consequences of these two theories are far-reaching. In the US，for example, blacks often score below whites on standardized intelligence tests. This leads some “nature” proponents to conclude that blacks are genetically lower in status than whites. Behaviorists, on the contrary, say that the differences in scores are due to the fact that blacks are often robbed of many of the educational and other environmental advantages that whites enjoy, and that, as a result, they do not develop the same responses that whites do.
Neither of these theories can yet fully explain human behavior. In fact, it is quite likely that the key to our behavior lies somewhere between these two extremes and that the controversy will continue for a long time is certain. This passage is mainly concerned with ________.
| A．relation between personality and behavior |
| B．relation between behavior and environment |
| C．different accounts of patterns of human behavior |
| D．different theories of the formation of human behavior |
The underlined word “proponents” in Paragraph 2 means ________.

In Paragraph 5, the author mainly writes about ________.
| A．the considerable influence of the two theories |
| B．differences between the blacks and whites |
| C．racial discrimination in the United States |
| D．different responds to intelligence tests |
What's the author's purpose in writing the passage?
| A．To call our attention to the changes of human behavior. |
| B．To urge scientists to do more research in social science. |
| C．To give us a detailed explanation of human behavior. |
| D．To present an argument in the field of social science. |
Mr. Hungerton, her father, really was absolutely centered upon his own silly self. If anything could have driven me from Gladys, it would have been the thought of such a father-in-law. I am convinced that he really believed in his heart that I came round to the Chestnuts three days a week for the pleasure of his company, and very especially to hear his views upon bimetallism (金银双币制).
For an hour or more that evening I listened to his tiring talk about bad money driving out good, and the true standards of exchange.
“Suppose,” he cried, “that all the debts in the world were called up at once, and immediate payment insisted upon, what under our present conditions would happen then?”
I gave the self-evident answer that I should be a ruined man, upon which he jumped from his chair, scolding me for my thoughtless quickness, which made it impossible for him to discuss any reasonable subject in my presence.
At last I was alone with Gladys, and the moment of Fate had come! She sat with that proud, slim figure of hers outlined against the red curtain. How beautiful she was! Gladys was full of every womanly quality.
I was about to break the long and uneasy silence, when two critical, dark eyes looked round at me, and the proud head was shaken disapprovingly. “I have a feeling that you are going to propose(求婚), Ned. I do wish you wouldn’t; for things are so much nicer as they are.”
I drew my chair a little nearer. “Now, how did you know that I was going to propose?” I asked in wonder.
“Don’t women always know? Do you suppose any woman in the world was ever taken unawares? But．．．oh, Ned, our friendship has been so good and so pleasant! What a pity to spoil it! Don’t you feel how splendid it is that a young man and a young woman should be able to talk face to face as we have talked?”
She had sprung from her chair, as she saw signs that I proposed to announce some of my wants. “You’ve spoiled everything, Ned,” she said. “It’s all so beautiful and natural until this kind of thing comes in! It is such a pity! Why can't you control yourself?”
“But why can’t you love me, Gladys? Is it my appearance, or what?”
“No, it isn’t that.”
“My character?”
She nodded severely.
“What can I do to mend it?”
She looked at me with a wondering distrust which was much more to my mind than her whole-hearted confidence.
“Now tell me what’s wrong with me?”
“I’m in love with somebody else,” said she.
It was my turn to jump out of my chair.
“It’s nobody in particular,” she explained, laughing at the expression of my face: “only an ideal. I’ve never met the kind of man I mean.”
“Tell me about him. What does he look like?”
“Oh, he might look very much like you.”
“How dear of you to say that! Well, what is it that he does that I don’t do? I’ll have a try at it, Gladys, if you will only give me an idea what would please you.”
“Well, it is never a man that I should love, but always the glories he had won; for they would be reflected upon me. Think of Richard Burton! When I read his wife’s life with him I could so understand her love! And Lady Stanley! Did you ever read the wonderful last chapter of that book about her husband? These are the sort of men that a woman could adore with all her soul, and yet be the greater, not the less, on account of her love, honored by all the world as the inspirer of noble deeds.”
“And if I do——”
Her dear hand rested upon my lips. “Not another word, Sir! You should have been at the office for evening duty half an hour ago; only I hadn’t the heart to remind you. Some day, perhaps, when you have won your place in the world, we shall talk it over again.”Why did the writer often come round to the Chestnuts?
| A．To hear Mr. Hungerton’s views upon bimetallism. |
| B．To find the opportunity of staying with Gladys. |

| B．Mr. Hungerton tried to stop the writer from proposing to his daughter. |
| C．It was difficult for Gladys to choose an ideal husband from her friends. |
| D．It was impossible for the writer to have any chance to marry Gladys. |

| B．Unfriendly, cold and self-centered. |
| C．Lovely, confident, and idealistic. |
| D．Simple-minded, active and attractive |
Grasshoppers are having to change their song — one of the iconic sounds of summer — to make themselves heard above the noise of road traffic, ecologists have discovered. The study, published in the British Ecological Society's journal Functional Ecology, is the first to show that human-made noise affects natural insect populations. Animals use sound to communicate for many reasons, including marking out territory, warning of predators and finding mates, and although previous research shows birds, whales and even frogs change their calls in noisy environments, the impact of human-made noise on insects has been neglected until now. Ulrike Lampe and colleagues from the University of Bielefeld in Germany caught 188 male bow-winged grasshoppers, half from quiet locations and half from beside busy roads. The grasshoppers use their song to attract mates.
The team then studied the differences in the two groups' songs in the laboratory. To encourage them to sing they exposed the males to a female grasshopper, and then recorded their courtship songs. Analysis of almost 1,000 recordings revealed grasshoppers living beside noisy roads produced different songs to those living in quieter locations.
According to Lampe: "Bow-winged grasshoppers produce songs that include low and high frequency components. We found that grasshoppers from noisy habitats increase the volume of the lower-frequency part of their song, which makes sense since road noise can mask signals in this part of the frequency spectrum(频谱)."
The team's findings are important because traffic noise could be upsetting the grasshopper's mating system(交配系统). "Increased noise levels could affect grasshopper courtship in several ways. It could prevent females from hearing male courtship songs properly, prevent females from recognizing males of their own species, or impair females' ability to estimate how attractive a male is from his song," Lampe explains.
Having discovered that human-made noise affects insect communication, the researchers now want to learn more about how the mechanism works, and whether the grasshoppers adapt to noise during their development as larvae（幼虫）, or whether males from noisy habitats produce different songs due to genetic differences.
The bow-winged grasshopper is a common species in Central Europe. Adults occur mainly between July and September, preferring dry grasslands. Around 1.5 cm long, they vary in colour from green and browns to red and purple. The male's song consists of 2 second-long phrases that increase in amplitude (振幅) towards the end. The beginning of a phrase is characterized by slower ticking sounds that increase in speed and amplitude, leading to a buzzing sound towards the end of the phrase. A courtship song usually includes 2 phrases.The author wrote the article to _________________.
