    A medical study has shown that excess(过度的)coffee drinking could cause heart attacks in people who do not metabolize(使新陈代谢)caffeine fast enough.

    The study, published recently in the Journal of the American Medical Association, says an enzyme(酶)that metabolizes caffeine in the liver works differently in some people, depending on the make­up of the gene(基因). People who have a slow version (版本)of the enzyme are at a greater risk(风险)of a heart attack when they drink more coffee. The risk had something to do with a person's age and how many cups of coffee he drinks.

    The team from the University of Toronto in Canada studied 4,024 people living in coffee­rich Costa Rica between 1994 and 2004, of whom half suffered non­fatal(非致命的)heart attacks. They found slightly more than half had the slow version of the gene, while the rest had the fast form.

    Two to three cups of coffee a day increased the possibilities of a heart attack by 36 percent for those with the slow­acting gene and four or more cups a day lifted it by 64 percent.

    But those under 50 who had the fast version of the gene had a lower risk of heart disease, even with four or more cups a day.

    Those with the fast­acting gene who drank two to three cups of coffee a day had 22 percent reduced possibilities of having a heart attack, but drinking four or more cups a day only lessened the risk by 1 percent. Scientists recommend limiting coffee consumption(消耗量)to within four cups a day.

(1)、People who have a slow version of the enzyme________.

A、are in danger when they drink coffee B、are living in coffee­rich Costa Rica C、have the slow version of the gene D、can not drink four or more cups of coffee a day
(2)、The example of Costa Rica the author presented in the passage proves that________

A、the heart attack in Costa Rica is really serious. B、the heart problem has something to do with drinking coffee. C、people in Costa Rica cannot metabolize caffeine in the liver. D、more than half people have the slow version of gene.
(3)、It can be concluded that the passage is most probably written for________

A、doctors who study heart disease B、specialists who offer medical care C、old people who have the slow version of the gene D、those who love drinking coffee every day
(4)、What is the best title for this passage?

A、Coffee and heart attacks B、Gene and heart disease C、Caffeine and enzyme D、Reasons for heart problems

    I was waiting for a phone call from my agent. He had left a message the night before, telling me that my show was to be cancelled. I called him several times, but each time his secretary told me that he was in a meeting and that he would call me later. So I waited and waited, but there was still no call. Three hours passing by, I became more and more impatient. I was certain that my agent didn't care about my work, and he didn't care about me. I was overcome with that thought. I started to shout at the phone, “Let me wait, will you? Who do you think you are?”

    At that time I didn't realize my wife was looking on. Without showing her surprise, she rushed in, seized the phone, tore off the wires, and shouted at the phone, “Yeah! Who do you think you are? Bad telephone! Bad telephone!” And she swept it into the wastebasket.

    I stood watching her, speechless. What on earth...?

She stepped to the doorway and shouted at the rest of the house, “Now hear this! All objects in this room—if you do anything to upset my husband, out you go!”

    Then she turned to me, kissed me and said calmly, “Honey, you just have to learn how to take control.” With that, she left the room.

    After watching a crazy woman rushing in and out, shouting at everything in sight , I noticed that something in my mood (情绪) had changed. I was laughing. How could I have trouble with that phone? Her anties helped me realize I had been driven crazy by small things. Twenty minutes later my agent did call. I was able to listen to him and talk to him calmly.

    Rainforests, it turns out, are not created equal. Take the Amazon rainforest, an area that covers about 7 million square kilometers. But within that huge expanse are all kinds of ecological zones, and some of these zones, says Greg Asner, are a lot more crowded than others.

    “Some forests have many species of trees,” he said, “others have few. Many forests are unique from others in terms of their overall species composition…” And all of these different small areas of forest exist within the giant space that is the Amazon Rainforest.

    So Asner, using the signature technique called airborne laser-guided imaging spectroscopy, began to map these different zones from the air. “By mapping the traits of tropical forests from above,” he explains, “we are, for the first time, able to understand how forest composition varies geographically.”

    The results show up in multicolored maps, with each color representing different kinds of species, different kinds of trees, the different kinds of chemical they are producing and using, and even the amount of biodiversity, the animal and plant species that live within each zone.

    Armed with this information, Asner says decision-makers now have “a first-time way to decide whether any given forest geography is protected well enough or not. If not, then new protections can be put in place to save a given forest from destruction.”

    Asner says the information is a great way for decision-makers to develop a “cost-benefit ratio type analysis.”  Conservation efforts can be expensive, so armed with this information, government leaders can ensure they are making the most of their conservation dollars by focusing on areas that are the most biologically diverse or unique.

    The next step, Asner says, is to take his project global, and to put his eyes even higher in the sky, on orbital satellites. “The technique we developed and applied to map Peru is ready to go global.” Asner said. “We want to put the required instrumentation on an Earth-orbiting satellite, to map the planet every month, which will give the best possible view of how the world's biodiversity is changing, and where to put much needed protections.

    “To another little girl.”

    That's what 3-year-old Ariana of Winterport, Maine, said when her father Josh Smith asked where her donated (捐赠的) hair was going to go. It was then that the dad of two realized his young daughter had a heart that was too big for words.

    “I run a charity called Extra Life where I play video games to help raise money for kids,” he said. “Ariana happened to be sitting next to me when a video was playing, showing a little girl who was bald(秃顶的), lying in a hospital bed with tubes in her.” When their daughter got curious, Smith and his wife Crystal explained how medicine was what made the child in the video lose her hair.

    “Without a second thought, Ariana said, 'She can have some of my hair,'” Smith said. “That's when my wife told me that there are many organizations that we could donate it to.” The Smiths chose “Locks of Love” to send Ariana's generous gift to a child with medical hair loss.

    A week later, Ariana was taken to the family hairdresser where 10 inches was cut from her hair.

    “It was her first haircut,” Smith told ABC News. “She can be so selfless like that. Her first reaction is 'How about me giving up something that I have, so a little girl can feel pretty?'” Smith posted his daughter's moving gesture on his personal webpage, where it has received almost 645,000 views in just two days.

    “She'll take an adult-like approach and it's really amazing,” Smith said. “She is just a little kid, but if she sees somebody in need, she certainly cares for them. This made Ariana feel special and she'd definitely like to do it again.”
