A new study finds that the animal known as man’s best friend can also be a good friend to the heart. Researchers in California say they have found that even just a short visit with a dog helped ease the worries of heart patients.
The study divided the patients into three groups. In Group A, a dog and a person visited each patient for twelve minutes. Patients in Group B received just a human visitor for twelve minutes. And members of Group C received no visitor, human or canine(犬的).
The dogs would lie on the hospital bed so the heart patients could touch them. The researchers say some patients immediately smiled and talked to the dog and the human visitor. Dogs, in her words, “make people happier, calmer and feel more loved.”
The researchers examined the patients before, during and after the visits. They measured stress levels based on blood flow and heart activity. They say they found a twenty-four percent decrease in the group visited by both a dog and a person. They reported a ten percent decrease in the group visited by a person only. There was no change in the patients without any visit. These patients, however, did have an increase in their production of the hormone epinephrine (epinephrine肾上腺素). The body produces epinephrine during times of stress.
The increase was an average of seven percent. But the study found that patients who spent time with a dog had a seventeen percent drop in their levels of epinephrine. Patients visited by a human but not a dog also had a decrease, but only two percent.
The author believes that _______.
A. the dog can take the place of most medicines
B. the dog is the most popular pet for man
C. the findings of the research cannot be trusted
D. visits by a human work better than visits by a dog
Which of the following best shows the stress level changes in the groups of patients? BACC
From the research findings we may conclude that _______.
A. the less the body produces epinephrine, the better
B. the longer a visit lasts, the happier the patient should be
C. the patients enjoyed the dogs’ company more than the human visitors’
D. it’s impossible for heart patients to recover without dogs’ visits
Which of the following is the best title for the passage?
A. Worried Heart Patients B. Epinephrine and Stress

A well-dressed man came into a famous jeweler shop. He explained that he wished to buy a pearl (珍珠) for his wife's birthday and that the price didn't matter since business had been very good for him that year. After examining a number of beautiful and valuable pearls, he chose a nice black one that cost $ 5,000. He paid for the pearl, shook hands with the jeweler and left.
A few days later the man returned and said his wife had liked the pearl so much that she wanted another one just like it. It had to be exactly the same size and quality(质地) as she wanted a pair of earrings (耳环) made. "Can you give me any advice on how to get such a pearl?" said the man. The jeweler replied, "I would say it's nearly impossible to find an exact one like that pearl.”

A morning rarely began so perfect. I took in the fresh air and felt my heart run into an enthusiastic rhythm. Though cool, the sun warmed my back as it rose over the horse from not far from my house. The slightest wind danced on my skin. Just enough to keep a runner form overheating. My ever-faithful jogging partner, a black dog named Nika pulled my leg with her mouth, mirroring my eagerness to start our run.
We raced forward with determination, ready to leap tall buildings and race against speeding trains. We pushed harder and ran faster, demonstration our skill and impressing passing motorists and neighbors.
We kept on running until we hit the Beast, a name for a very difficult, nearly two-mile long steep climb.
Only a few paces into the Beast, I gasped for air. Far short of superhero status, my enthusiasm and active steps were lost somewhere at the base of the hill. A vision of the newspaper and a cup of coffee waiting in my kitchen appeared, attracting me to turn back toward home.
With a glance I noticed Nika wasn’t doing any better. She continued to faithfully follow me, putting one paw in front of the other, but without her former eagerness. Her tiredness touched me. And in that moment, I felt a sudden spark of renewed determination to press on. I couldn’t allow this mountain to get the better of us. To improve both our spirits, I managed to shout, “Good girl, Nika! Keep going…you can do it!”
“I’m encouraging a dog, for heaven’s sake!’’ I needed to pull myself together. With a few simple words, I changed our course. One moment we were on the edge of quitting. The next, our feet picked up the pace and we continued. Though tired and discouraged myself, with a few kind words I impacted a dog’s ability to go further. I’m sure I could have completed the opposite with ill-chosen comments and an unpleasant tone. Instead, the Beast was defeated and we flew like heroes the rest of the way home.
Life is full of beasts to conquer. For some, it is the seemingly impossible climb of cancer. For others, their beast takes the shape of parenting a child or a teenager. Uphill climbs come in all shapes and sizes, common only in their ability to defeat, discourage and tempt tired travelers to quit. Sometimes all that’s needed is a few spoken, well-timed words of encouragement from a fellow runner – someone who sees the struggle, dares to jogs alongside, and cares enough to say, “Keep going! You can do it! You’re not alone. I believe in you!”
