    It was 11 a.m. on October 8, 2018, when I set out on the 12-mile bike ride home from work along the Connecticut shoreline. The sun was brilliant 1 the blue sky, and the leaves were starting to change colors. It was a(n) 2 time for me.

    I love my job as a program manager at Peace Jam. My husband Sean, a mail carrier, was 3 with his work, so I'd made plans with a friend for a long ride later that afternoon.4 I settled into the right-hand lane of a busy avenue, a truck turned in my direction from a side street. He slowed at the corner. But for some reason, he suddenly 5 speed. There is nothing I could do but scream.6, the huge truck knocked me down onto my left side. I felt my leg cracking, but I still 7 my head just enough to see something sticking out from my leg. The skin had been 8 right off most of the lower half of my body. There wasn't any 9 flesh to see. People came rushing from all 10 and aided me. The doctors arrived and rolled my body onto a backboard. I was sent 11 to the emergency room, where, for the next eight hours, I kept dying. During this period, I was in and out of surgery several times. Sometimes I was unconscious, but other times I existed in a 12 that has no easy comparison. What 13 me out of my fear was remembering a speech by Nobel Prize Jody Williams. "Emotion without action is irrelevant".

    I thought of all the people who had saved my life. The strangers who ran to my side after the truck hit me; the 14 who brought me back from death more than once; the staff at Gaylord who were 15 to help me walk again and relearn basic tasks. And then there were the strangers who had donated their life-giving blood. Suddenly I felt a need to do something to 16 them. I may not have been able to walk yet, but I 17 organize a cycling tour to raise money for disabled athletes. I 18 raising more than ＄10.000. Then, I turned inward, concentrating on my own recovery.

    My injury also made me 19 just how lucky I am. In the darkest moments of being 20 in the coma（昏迷）their voice constantly comforts me. To this day, I am gratitude in motion with each step.

    Which kind of diamond is better for the environment and the world we live in: a diamond from a traditional mine or one made in a laboratory?

    Some recent reports suggest the answer may not be so clear. At the very least, these reports provide evidence of tensions between two different sectors of the diamond industry.

    Lab -grown diamond companies say they are more ethical and cause less harm to Earth's environment. The traditional diamond sector notes that its businesses help the communities where they operate mines. It says they provide jobs, help build roads and other infrastructure and make investments in conservation.

    Some companies, such as De Beers, work on both sides. De Beers sells natural and man-made diamonds. In the United States, the Federal Trade Commission(FTC) investigates reports of deceptive, or misleading, advertising. In April, the commission sent warning letters to eight lab-grown diamond companies. One of the FTC's concerns was the use of the word 'eco-friendly', and similar terms, to describe diamonds made in a laboratory. The lab-grown process requires very high temperatures and uses a lot of energy. Trucost is a company that estimates the costs of using natural resources. Asked by the Diamond Producers Association to study the issue, Trucost found the carbon intensity of natural diamonds was lower than lab-grown diamonds.

    The Trucost report did note that diamond miners should reduce their effect on the environment by using more renewable energy, such as wind power and sunlight.

    Ahead of the summer travel season, airlines in the United States usually compete to sell tickets and fill seats. But the airlines that operate the grounded Boeing 737 Max planes have a new problem: there are not enough seats to meet the demand.

    The revenue(收益)is right in front of them. They can see it, but they can't meet it, said Mike Trevino. He is an airline industry expert for Southwest Airlines Pilots Association, The grounding of Boeing's 737 Max came after two deadly crashes in five months. Southwest Airlines is the world's largest 737 Max operator. The company has 34 of the planes.

    American Airlines operates the second-most, with 24. These planes have been removed from use until at least August, The grounding of the planes has led Southwest to cancel 160 of its 4,200 daily flights between June 8 and August 5.

    American Airlines will cancel 115 daily flights, or 1.5 percent of its total summer flights .Southwest only flies Boeing 737s. It had estimated $ 150 million in lost revenue between February and March 31--mostly because of MAX cancellations.

    The 737Max was grounded worldwide in March following a deadly Ethiopian Airlines crash. It came five months after a Lion Air crash in Indonesia. All on board both planes died.

    Boeing is under pressure to provide additional software. Experts are examining the original software as a possible reason for the crashes.

    Boeing must prove to worldwide regulators that the plane is safe to fly. That process may take more than 90 days. Planes in the United States are usually mostly full during the months of June, July and August.

    In 1988, after being diagnosed with kidney cancer, Fenn, a high-end gallery owner, came up with a crazy plan: He would bury some of his favorite artifacts somewhere in the Rocky Mountains and then die next to them. "My desire was to hide the treasure and let my body stay there and go back to the soil," he explains.

    The contents are worth somewhere between $I million and $5 million. Then he took his treasure chest out into the Rockies and hid it.He wanted it to be found. But he wasn't going to just give it away.

    In 2010, Fenn self-published a book, The Thrill of the Chase, which includes a 24-line poem that Fenn claims contains nine clues that "will lead to my treasure."

    At first, nobody really noticed. But word spread, and the chase was on.(The book is now out of print, and copies show up on Amazon for as much as $3,200.) Fenn estimates that 350,000 people from across the globe have searched or are currently searching for his treasure. Yet nobody has found it.

    The problem with Fenn's poem is that the "clues" can be interpreted a million different ways. The "home of Brown," for instance, could be Browns Canyon National Monument in Colorado, or Brown Hill in New Mexico. Or a cabin or a bear.(Don't laugh; several people have already looked.)

    "It's all in the poem," some have recently started sharing more details," and the treasure isn't in a mine, I mean, they have snakes in' em. It's between 5,000 feet and 10,200 feet above sea level. It's not in Canada or Idaho or Utah or a grave-yard."

    Why are Fenn's treasure hunters so into what seems like a ridiculous thing to do with their time? Many are quick to say that their lives have been enriched by their experiences. "It's changed us," Neitzel says. "made us more confident, and even saved our marriages. Nothing scares us anymore." They thank Fenn for giving them a reason to take a risk, for giving their lives meaning. Many claim that even if they found Fenn's chest, they wouldn't necessarily spend the money—and might even rehide the chest. Another hunter had this tantalizing insight: "I hope that I never find the treasure. The journey will be treasure enough."

    And so the hunt continues.

    Studies show that human beings and cats have been living together for about 9,500 years.

     Dogs are domesticated, meaning they have been trained to do what people want them to do.

    As cat owners know well, cats do not obey humans in the same way dogs do.

    As a result, many people have come to think that maybe cats simply do not understand human language. A report in the scientific journal Nature shows that cats understand human beings well enough to recognize their own names.

    The report describes a series of experiments with house cats in Japan. These tests involved having people say four words that were similar to a cat's name.

    Each word had the same number of syllables as the name and some of the some sounds. The cats seemed to lose interest after the speaker said a few of the words.

    The cats moved their ears or turned their head when they heard their names. They also moved their feet gr bogies very little-not a surprising result.  These animals reacted just as much to their own names.

    The researchers thought this was because visitors may give food to the cat or rub its back when it responds. Another finding was that a cat will react when a person who is not its owner says its name.

    "I think many cat owners feel that cats know their names, or the word "food".says Saito, who is a cat owner.The researchers hope that the findings from their study will help both cats and people.

A.Then the person said the cat's name.

B.In fact, some scientists claim that cats have trained us to take care of them.

C.They added that perhaps cats can learn words to warn them of dangerous things or places.

D.Dogs have lived with humans longer than cats.

E.The study was carried out by four researchers: Atsuko Saito, Yuki Ito, and Toshikazu Hasegawa and Kazutaka Shinozuka of the RIKEN Center for Brain Science in Saitama.

F.But until now, there was no scientific evidence to back that up.

G.In another part of the experiment, people said the names of the cats staying in a cat cafe

    Spending my childhood at the farm is a truly unforgettable experience so far. The life  I led there with my parents was full of attraction, and  is memory of it yet. I can call back the scenes of sunsets, the mystery of deep forests, the early smells, the faint odors(味道)of wild flowers, the shiny appearance of rain-washed leaves, the gentle sounds of drops when winds  (shake) the trees,  the far-off drumming of wood long-tailed birds in the distance of the forests,  disturbed wild creatures were seen to move through the grass quickly--I can call it all back and make it as real  it ever was. I can call back the grasslands, and its  (lonely) and peace, and a huge eagle hanging still in the sky, with his wings spread  (wide) in the blue sky. I can see the woods in their autumn dress, the oak purple, the hickories(山核桃)washed with gold and the maples shining with crimson (深红的)fires, and I can hear the rustle made by the  (fall) leaves as we walked through them. I can see the blue bunches of wild grapes hanging  the leaves, and I remember the taste of them and the smell.
