How many afternoons have you slowly moved over to the office coffee machine and wondered: Is this really my fourth cup of the day? Or wait, is it my fifth? We've all been there, but a new study shows refilling your cup too often could be hurting your health.

The study, published in The American Journal of Clinical Nutrition suggests that drinking six or more cups of coffee per day may increase your risk of heart disease by up to 22%. Researchers from the University of South Australia also found a specific gene, called CYP1A2, which enables people to consume caffeine faster than those without it.

Overall, the researchers found that people who drank six or more cups of coffee a day were 22% more likely to develop cardiovascular （心血管的）disease, compared to those who drank one to two cups daily. The study authors believe that coffee （in large quantities） and heart problems may be linked because excess caffeine consumption can cause high blood pressure, a risk factor for cardiovascular disease.

Most people would agree that if you drink a lot of coffee, you might feel nervous and irritable （易怒的）.That's because caffeine helps your body work faster and harder, but it is also likely to suggest that you may have reached your limit for the time being. That doesn't mean that any and all coffee is bad for your heart, however. In fact, the researchers also found that participants who didn't drink coffee at all — and those who drank decaf — also had higher rates of heart disease （11% and 7% higher, respectively） than those who drank one to two cups per day. Previous research has found coffee is rich in antioxidants （抗氧化物质） and may reduce the risk of heart disease, stroke, and diabetes.

    This happened several years ago when I was still quite new in the city. I was doing my grocery shopping one day, and when I wanted to pay for my things, it turned out that I didn't have enough funds on my bank account for the things I’d chosen. It seemed something had been paid from my account that I had forgotten about.

I was so embarrassed and ashamed. There was a queue forming behind me. I became very flustered（慌乱的）and very close to tears. I tried to quickly pick some things out that weren’t so urgent for me to buy. The cashier（收银员）, a patient, elderly man, saw how upset I was and gently said, “Please, don't worry about picking out groceries to leave behind and you can pay me back for the difference another day.” I immediately refused since I didn't know him, but he insisted he would pay for the difference because he also had daughters and sometimes life could be hard. I thanked him greatly while I packed my things. I asked him what his name was so I could bring the money another day. He said, “Just ask for Baba（Father）and everyone calls me that here.”

I came back a few days later with the money, a thank-you card, and some homemade cookies. I asked a young salesman if he'd seen the old man and he immediately told me, “Oh! That must be Baba!” It was clear that he was very familiar with him. I explained what had happened and he nodded. "Yes, that is something he would do. He is a bit of an extra father to all of us working here, too. He isn't working today but I will make sure he gets this."

Thank you, Baba, for looking out for me that day, and for taking good care of your coworkers, too! I think it is people like Baba that make the world beautiful.

阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。

It was a Sunday morning. Betty woke up earlier than usual. She couldn’t sleep any longer because she was so excited that her uncle Mark was taking her to the beach. She had always loved going surfing with her uncle. She put her swimming suit on and took her bag quickly that she had prepared the night got before and went outside to wait. She jumped up and down with joy when she saw her uncle’s red jeep turn the corner down her street.

Uncle Mark got out of the car and helped Betty get in. “Are you ready?” he asked. “Yes!” replied Betty. Uncle Mark could see the excitement in her face. Suddenly he said seriously, “Well, before we go, I have to let you know that a shark appeared recently where we're going to surf today.” Scared and shocked, Betty couldn’t say a word. “Haha! I'm kidding you,” Uncle Mark burst out laughing. Betty laughed too. She knew Uncle Mark liked teasing others. “Let’s go and have some breakfast, I know just the place,” Uncle Mark said. They went                to a breakfast shop and ate some tacos (炸玉米饼).

After breakfast the two of them went down to Pacific Beach and got their surfboards ready. “First you have to wax(打蜡)the bottom,explained Uncle Mark. “I know. I’ve watched you do it before!" Betty said as she took the wax from Uncle Mark's hand. It took about 15 minutes to wax the bottom of their boards. When Betty finished, Uncle Mark looked it over to make sure it was done well. “Nice job, Betty, you wax your board like a true surfer.”

Finally, they were ready to get into the water. They carried their boards down to the beach and went out into the water. Betty was overly excited and tried to rush to catch a wave. Predictably, she crashed and had to start over. Next was her uncle's turn. He stood up on his first try and smoothly surfed the wave before jumping into the water. Betty cheered for her uncle's perfect run.

What If We Don’t Get Along?

Teachers want to get along with you and enjoy seeing you learn. But teachers and students sometimes have personality clashes（人格冲突）. 1. If you show your teacher that you want to make the situation better, he or she will probably do everything possible to make that happen. Take these steps if the problem seems difficult to solve:

1. Talk to an adult you trust, such as a parent, guidance counselor, or both.

2. 2. You may not feel immediately comfortable with your teachers, but that may change as you get to know one another.

3. If you’ve given it time, talk with your parents about what to do next. Lots of times, a meeting can be set up to discuss the problem. 3. Everyone’s goal should be to create trust and kindness.

Your relationship with your teachers is often your first chance to develop a “business relationship”. They are different from your family relationships and friendships, which are built on affection and love. 4. But they don’t necessarily need to be good friends or like each other a lot. They simply need to respect one another, be polite, and stay focused on the jobs at hand.

When you act this way, and remember that you’re not the only kid in the class, you are

helping your teacher. 5. Teachers also like it when students follow directions and when they learn and obey the rules of the classroom. For instance, there may be rules about listening when another student is talking, about taking turns, or about raising your hand when you want to say something or ask a question.

A.Give it time.

B.This can happen between any two people.

C.This may clear the air and make things better.

D.Your teacher is likely to notice this and appreciate it.

E.Therefore, those teachers rarely show respect towards their students.

F.A teacher cannot necessarily answer all the questions his students ask.

G.In a business relationship, both parties get something out of the relationship.

    At 88, I remain a competitive runner. The finish line of my life is drawing close, and I hope to reach it having given the best of myself along the way. I’ve been training my body to meet the demands of this final stretch. But, I wonder, should I have asked more of my mind?

If I didn’t exercise, I would release the hungry beasts that seek their elderly prey on couches, but not in the gym. The more I sweated, the more likely it was my doctor would continue to say, “Keep doing what you’re doing, and I’ll see you next year.” My mind, on the other hand, seems less willing to give in to discipline. I have tried internet “brain games”, solving algebraic problems flashing past and changing the route of virtual trains to avoid crashes. But these never approach my determination to remain physically fit as I move deeper into old age.

Despite having many friends in their 70s, 80s and 90s, I’ve been far too slow to realize that how we respond to aging is a choice made in the mind, not in the gym. Some of my healthiest friends carry themselves as victims abused by time. Other friends, many whose aching knees and hips are the least of their physical problems, find comfort in their ability to accept old age as just another stage of life to deal with. I would use the word “heroic” to describe the way they cope with aging.

One such friend recently called from a hospital to tell me a sudden brain disease had made him legally blind. He interrupted me as I began telling him how terribly sorry I was, “Bob, it could have been worse. I could have become deaf instead of blind.”

Despite all the time I spend lifting weights and exercising, I realized I lack the strength to have said those words. It suddenly struck me I’ve paid a price for being a “gym rat.” If there is one characteristic common to friends who are aging with a graceful acceptance of life’s attacks, it is contentment. Aging had to be more than what I saw in a mirror.

But rather than undertaking a fundamental change in the way I face aging, I felt the place to begin would be to start small. A recent lunch provided a perfect example.

I’ve always found it extremely difficult to concentrate when I’m in a noisy setting. At this lunch with a friend in an outdoor restaurant, a landscaper began blowing leaves from underneath the bushes surrounding our table. Typically, after such a noisy interruption, I would have snapped, “Let’s wait until he’s finished!” then fallen silent. When the roar eventually faded, my roar would have drained (消耗) the conversation of any warmth. It troubled me that even a passing distraction could so easily take me from enjoying lunch with a good friend to a place that gave me no pleasure at all. I wanted this meal to be different.

My years in gyms had taught me to shake off pains and other distractions, never permitting them to stop my workout or run. I decided to treat the noise this way. I continued talking with my friend, challenging myself to hear the noise, but to hold it at a distance. The discipline so familiar to me in the gym - this time applied to my mind - proved equally effective in the restaurant. It was as though I had taken my brain to a mental fitness center.

Learning to ignore a leaf blower’s roar hardly equips me to find contentment during my passage into ever-deeper old age. But I left the lunch feeling I had at least taken a small first step in changing behavior that stood in the way of that contentment.

Could I employ that same discipline to accept with dignity the inevitable decline awaiting me like the finish line? Hoping that contentment will guide me as I make my way along the path yet to be traveled.

    In the famous musical My Fair Lady, Eliza Doolittle, the poor daughter of a dustman who speaks with a thick Cockney accent, becomes the unwitting (不知晓的) target for a bet between two phonetics scholars. By the end of the musical, Doolittle is able to pronounce all of her words like a member of the British elite, fooling everyone at an embassy ball about her true origins.

It’s hard to imagine a version of My Fair Lady set in the U.S. because, unlike the British, Americans seem either unwilling or unable to honestly acknowledge their own social class. But a new set of scientific studies conducted by Michael Krauss and his colleagues at Yale University show that Americans find it easy to make distinctions about other people’s social class just by listening to them speak.

In one study, the researchers asked 229 people to listen to 27 different speakers who varied in terms of their age, race, gender and social class. The participants heard each speaker say a total of seven different words. Based on just this short audio, participants were able to correctly identify which speakers were college-educated 55 percent of the time-more than what would be expected by chance. A major limitation of this study, however, was that it used college education as a criterion for social class.

Then in another experiment, 302 participants were asked to either listen to or read transcripts (文本) from 90 seconds of recorded speech in which the speakers talked about themselves without explicitly mentioning anything about their social class. Participants were asked to judge what they thought the social classes of the speakers were by using a 10-rung ascending (上升的) ladder of increasing income, education and occupation. They found that participants who heard the audio recordings were more accurate in judging where the speakers fell in terms of their social status.

To show whether these inferences have real-world consequences, Kraus and his colleagues ran another experiment. They recruited 274 participants, all of whom had past hiring experience, to either listen to the audio or read a transcript of the content. The findings showed that participants were able to accurately judge the social class of the candidates and that this effect was stronger for participants who had heard the audio recordings. In addition, participants judged the higher-class candidates as more competent, a better fit for the job and more likely to be hired.

Taken together, this research suggests that despite our discomfort about the topic, Americans are able to easily detect one another’s social class from small snippets of speech. Moreover, we use this information to discriminate against people who seem to be of a lower social class. This research identifies social class as another potential way that employers may discriminate against candidates, perhaps without even realizing it.
