Women are friendly．But men are more competitive．Why? Researchers have found it's all down to the hormone oxytocin （荷尔蒙催生素）．Although known as the love hormone, it affects the sexes differently．
"Women tend to be social in their behavior．They often share with others．But men lend to be competitive．They are trying to improve their social status," said Professor Ryan．
Generally, people believe that the hormone oxytocin is let out in our body in various social situations and our body creates a large amount of it during positive social interactions （互动） such as falling in love or giving birth．
But in a previous experiment Professor Ryan found that the hormone is also let out in our body during negative social interactions such as envy．
Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relationships, but in women it raises the ability to recognize friendship．
Professor Ryan's recent experiment used 62 men and women aged 20 to 37．Half of the participants（参与者）received oxytocin．The other half received placebo （安慰剂）．
After a week, the two groups switched with participants．They went through the same procedure with the other material．
Following each treatment, they were shown some video pictures with different social interactions．Then they were asked to analyze the relationships by answering some questions．The questions were about telling friendship from competition．And their answers should be based on gestures, body language and facial expressions．
The results indicated that, after treatment with oxytocin, men's ability to correctly recognize competitive relationships improved, but in women it was the ability to correctly recognize friendship that got better．
Professor Ryan thus concluded: "Our experiment proves that the hormone oxytocin can raise people's abilities to better distinguish different social interactions．And the behavior differences between men and women are caused by biological factors （因素） that are mainly hormonal．"What causes men and women to behave differently according to the text?
| A．Placebo． | B．Oxytocin． |
| C．The gesture． | D．The social status． |
What can we learn from Professor Ryan's previous experiment?
| A．Oxytocin affects our behavior in a different way． |
| B．Our body lets out oxytocin when we are deep in love． |
| C．Our body produces oxytocin when we feel unhappy about others' success． |
| D．Oxytocin improves our abilities to understand people's behavior differences． |
Why did Professor Ryan conduct the recent experiment?
| A．To test the effect of oxytocin on the ability to recognize social interactions． |
| B．To know the differences between friendship and competition． |
| C．To know people's different abilities to answer questions． |
| D．To test people's understanding of body language． |
The author develops the text by______．
| A．explaining people's behaviors |
| B．describing his own experiences |
| C．distinguishing sexual differences |
| D．discussing research experiments |
Although being famous might sound like a dream come true, today’s star, feeling like zoo animals, face pressures that few of us can imagine. They are at the center of much of the world’s attention. Paparazzi (狗仔队) camp outside their homes, cameras ready. Tabloids (小报) publish thrilling stories about their personal lives. Just imagine not being able to do anything without being photographed or interrupted for a signature.
According to psychologist Christina Villareal, celebrities （ famous people名人) worry constantly about their public appearance. Eventually, they start to lose track of who they really are, seeing themselves the way their fans imagine them, not as the people they were before everyone knew their names. “Over time,” Villareal says, “they feel separated and alone.”
The phenomenon of tracking celebrities has been around for ages. In the 4th century B.C., painters followed Alexander the Great into battle, hoping to picture his victories for his admirers. When Charles Dickens visited America in the 19th century, his sold-out readings attracted thousands of fans, leading him to complain about his lack of privacy(隐私). Tabloids(小报) of the 1920s and 1930s ran articles about film-stars in much the same way that modern tabloids and websites do.
Being a public figure today, however, is a lot more difficult than it used to be. Superstars cannot move about without worrying about photographers with modern cameras. When they say something silly or do something ridiculous, there is always the Internet to spread the news in minutes and keep their “story” alive forever.
If fame is so troublesome, why aren’t all celebrities running away from it? The answer is there are still ways to deal with it. Some stars stay calm by surrounding themselves with trusted friends and family or by escaping to remote places away from big cities. They focus not on how famous they are but on what they love to do or whatever made them famous in the first place.
Sometimes a few celebrities can get a little justice. Still, even stars who enjoy full justice often complain about how hard their lives are. They are tired of being famous already.It can be learned from the passage that stars today______
| A．are often misunderstood by the public |
| B．can no longer have their privacy protected |
| C．spend too much on their public appearance |

| B．The problem faced by celebrities has a long history. |
| C．Well-known actors are usually targets of tabloids. |
| D．Works of popular writers often have a lot of readers. |

| D．Huge population of fans. |
What is the author’s attitude toward modern celebrity?

When your pet has an emergency, first aid is not a substitute for veterinary（兽医） treatment. However, before you are able to get your pet to a veterinarian（兽医）, knowing some basic first aid can help.
Bite Wounds
Approach the pet carefully to avoid getting bitten. Wear a mask for the animal and then check the wound. Clean the wound with large amounts of saline(盐水). If these are not available, then regular water may be used. Wrap large open wounds to keep them clean.
Bleeding
Apply firm, direct pressure over the bleeding area until the bleeding stops. Hold the pressure for at least 10 minutes. Avoid bandages that cut off circulation.
__________
Check to see if the animal is choking（窒息） on a foreign object. If an animal is not breathing, place it on a firm surface with its left side up. Check for a heartbeat. If you hear a heartbeat but not breathing, close the animal’s mouth and breathe directly into its nose—not the mouth—until the chest expands. Repeat 12 to 15 times per minute.
Burns
Wash the burn immediately with large amounts of cool, running water. Apply an ice pack for 15—20 minutes. Do not place an ice pack directly on the skin. Wrap the pack in a light towel or other cover. If the animal has large quantities of dry chemicals on it skin, brush them off. Water may activate some dry chemicals.
Fractures (骨折)
Symptoms include pain, inability to use a limb (腿). Wear a mask for the pet and look for bleeding. If you can control bleeding without causing more injury, then do so. Watch for signs of shock.

My 18-month-old son, Adam, called from the front door. “Look, Mama! Doggie!” I dropped what I was doing and stuck my head out of the door. Brandy, our next-door neighbor’s 11-year-old dog, was over again. “Go away!” I shouted.
Brandy’s owner had died about a month earlier. The woman’s family had emptied the house and stuck a “For Sale” sign in the front yard, but the family had left old Brandy behind. For weeks, she’d been wandering around the neighborhood.
It wasn’t that I disliked dogs or anything like that. I just didn’t think about them very much. I never had a dog growing up and had never thought to get one.
Brandy went away and I stayed outside with Adam. Then the phone rang. I went inside to take the call. When I came back, Adam was gone. I searched the yard, front and back, then the basketball court and public pool. No trace of him. I was so nervous that I ran home and called the police, then my husband.
Police searched the neighborhood. Suddenly I heard anothersound: a dog barking. “It’s coming from the woods,” one of my neighbors said. We followed the barking to a wooded cliff（悬崖）. There we found my son, and he was just inches away from the edges of the cliff, fast asleep. Brandy was beside him, leaning（斜靠着）against him to keep him away from the edge（边缘）. When I picked Adam up, Brandy sank down on her side, breathing quickly. She must have been holding Adam there for hours!
I thanked the police and brought Adam and Brandy back to our house. She hesitated a moment on our doorstep, no doubt remembering the time I’d driven her away.
“Come on, girl,” I said. “This is your home now. ” Brandy stepped in, and once she saw she was really welcome, she relaxed and lay down on the floor just inside the door. She’d done a great thing, and I wondered if she knew it. She’d certainly touched me in a way that no animal ever had. What a pity a dog like Brandy had been left behind!What is the correct order for the events in the story about Brandy?
a. She was left behind by her owner’s family.
b. She stepped into the woman’s house.
c. She appeared at the woman’s front door.
d. She stayed beside the woman’s son for hours.

| C．c, d, b, a | D．a, c, d, b |
What did the woman do when she first saw Brandy?
| A．She gave her some food. | B．She took her home. |
| C．She drove her away. | D．She said thank you to her. |
How were they able to be aware that the woman’s son was near the cliff?
| A．By searching the neighborhood. |
| B．By hearing a dog barking. |
| C．By following a dog’s footsteps. |
| D．By hearing her son’s crying. |
What’s the woman’s attitude towards Brandy at the end of the story?
| A．Gratitude. | B．Dislike. |
| C．Sympathy. | D．Indifference. |
At Denver there was an crowd of passengers into the coaches（车厢） on the eastbound B. & M. express. In one coach there sat a very pretty young woman dressed in elegant taste and surrounded by all the luxurious comforts of an experienced traveler. Among the newcomers were two young men, one of handsome presence with a bold, frank face expression and manner; the other a ruffled, glum-faced person, heavily built and roughly dressed. The two were handcuffed（拷上手铐） together.
As they passed down the aisle of the coach the only available seat offered was a reversed one facing the attractive young woman. Here the linked couple seated themselves. The young woman's glance fell upon them with a distant, swift disinterest; then with a lovely smile brightening her face and a tender pink tingeing（稍加染色，影响） her rounded cheeks, she held out a little gray-gloved hand. When she spoke her voice, full, sweet, and deliberate, proclaimed that its owner was accustomed to speak and be heard.
"Well, Mr. Easton, if you will make me speak first, I suppose I must. Don't you ever recognize old friends when you meet them in the West?"
The younger man aroused himself sharply at the sound of her voice, seemed to struggle with a slight embarrassment which he threw off instantly, and then clasped her fingers with his left hand.
"It's Miss Fairchild," he said, with a smile. "I'll ask you to excuse the other hand; "it's otherwise engaged just at present."
He slightly raised his right hand, bound at the wrist by the shining "bracelet" to the left one of his companion. The glad look in the girl's eyes slowly changed to a bewildered horror. The glow faded from her cheeks. Her lips parted in a vague（含糊，犹豫）, relaxing distress. Easton, with a little laugh, as if amused, was about to speak again when the other forestalled him. The glum-faced man had been watching the girl's face expression with veiled glances from his keen, shrewd eyes.
"You'll excuse me for speaking, miss, but, I see you're acquainted with（认识，熟悉） the officer here. If you'll ask him to speak a word for me when we get to the pen（围栏，监狱） he'll do it, and it'll make things easier for me there. He's taking me to Leavenworth prison. It's seven years for cheating."
"Oh!" said the girl, with a deep breath and returning color. "So that is what you are doing out here? An officer!"
"My dear Miss Fairchild," said Easton, calmly, "I had to do something. Money has a way of taking wings with itself, and you know it takes money to keep step with our crowd in Washington. I saw this opening（通道） in the West, and--well, an officer isn't quite as high a position as that of ambassador, but--"
"The ambassador," said the girl, warmly, "doesn't call any more. I needn't ever have done so. You ought to know that. And so now you are one of these brave Western heroes, and you ride and shoot and go into all kinds of dangers. That's different from the Washington life. You have been missed from the old crowd."
The girl's eyes, fascinated, went back, widening a little, to rest upon the glittering handcuffs.
"Don't you worry about them, miss," said the other man. "All officers handcuff themselves to their prisoners to keep them from getting away. Mr. Easton knows his business."
"Will we see you again soon in Washington?" asked the girl.
"Not soon, I think," said Easton. "My butterfly days are over, I fear."
"I love the West," said the girl irrelevantly. Her eyes were shining softly. She looked away out the car window. She began to speak truly and simply without the gloss of style and manner: "Mamma and I spent the summer in Denver. She went home a week ago because father was slightly ill. I could live and be happy in the West. I think the air here agrees with me. Money isn't everything. But people always misunderstand things and remain stupid--"
"Say, officer," shouted the glum-faced man. "This isn't quite fair. I'm needing a drink, and haven't had a smoke all day. Haven't you talked long enough? Take me in the smoker now, won't you? I'm half dead for a pipe."
The bound travelers rose to their feet, Easton with the same slow smile on his face.
"I can't deny a require for tobacco," he said, lightly. "It's the one friend of the unfortunate. Good-bye, Miss Fairchild. Duty calls, you know." He held out his hand for a farewell.
"It's too bad you are not going East," she said, reclothing herself with manner and style. "But you must go on to Leavenworth, I suppose?"
"Yes," said Easton, "I must go on to Leavenworth."
The two men sidled down the aisle into the smoker.
The two passengers in a seat near by had heard most of the conversation. Said one of them: "That officer is a good sort of man. Some of these Western fellows are all right."
"Pretty young to hold an office like that, isn't he?" asked the other.
"Young!" exclaimed the first speaker, "why--Oh! Didn't you catch on? Say--did you ever know an officer to handcuff a prisoner to his right hand?"From the first three paragraphs, we know that_________
