Diamonds are considered the most famous and valuable jewel in the world. The precious stone for its great value is believed to be the symbol of wealth. Diamonds were made as a result of great volcanic beat and pressure. When a volcano is active, it sometimes explodes and causes great damage to the nearby towns.

    However, at the same time of such a disaster, diamonds were pushed towards the surface of the earth by a number of great volcanic explosions millions of years ago. Thus, it may be very likely to find a diamond after a volcanic eruption. Besides, diamonds are also found among the sand and stones of certain river beds, and in a few places on the floor of the sea, for they were washed down the mountain sides by the rain.

    Diamonds are very rare. There are not many places that produce such precious things in the world. During the last century adventurers from Europe went to Brazil, because they had heard that there were diamonds in the River Amazon. Many of these early diamond miners died of illness or were lost forever in the great forests. But some returned home rich.

    The earliest known diamonds were found in India many centuries ago. The most recent and exciting discoveries have been made in eastern Russia. But most of the world's diamonds now come from the Congo, from Tanzania-which has the largest diamond mine in the world and also from South Africa.

    Smartphones, tablets and laptops make it easy for people to work on the go, but traditionally, printers have been cumbersome to move out of the office. However, the new Zuta Pocket Printer will enable people to print anywhere. The Zuta Pocket Printer was invented by Zuta Labs, based in Jerusalem. This small printer is about 10.2 cm wide and long and 7.5 cm high, and weighs about 350 grams. The company plans to ship its printers to customers in the beginning of 2017.

    This printer can connect wirelessly to smart phones, tablets, laptops and PCs via Wi-Fi, and is supported by Android, iOS, OS X and Windows. A free application from the company lets you use the printer via a mobile appliance; a laptop or PC can also select the printer for Use just like any other wirelessly connected printer. This printer can print one average A4 page, measuring 21 by 29.7 cm. Zuta Labs noted that its printer can print on any standard size piece of paper, and that, in principle, it could print on any surface.

    The printer's," omni-wheels" help it turn and move in any direction on a surface. Laser sensors（激光传感器）help control the movement, speed and location, according to the company.

    Zuta Labs said the printer's rechargeable battery can last about l hour, on average—long enough to print about 60 pages. One ink cartridge（墨盒）can print more than 100 pages, according to the company. Currently, the appliance prints only in black, although Zuta Labs said it plans to have a full-color printer in the future.

    On a cold morning in 2015, five-year-old Lucas stood on the bank of Blue Star River, hugging a dead salmon（鲑鱼）against his thick yellow coat. He looked up at his father, Steve, who nodded encouragingly. "Go ahead," he said. "Put it in." The young boy dragged his feet forward and held the fish as far as he could into the shallow water. "It's floating!" Lucas yelled, delighted. For a moment, it's almost as if the handsome salmon could come back to life.

    Lucas' salmon was just one of 100 or so dead bodies that will land in Blue Star River in a half-hour activity this morning, delivered by dozens of volunteers. None of the salmon will rise from the dead, but Andy, president of the Fish Rescue Society, who has promoted this gathering, is carrying out the resurrection （复活）project of salmon.

    Andy led the group's campaign to recover this urban waterway's salmon population. "The Fish Rescue Society started exploring the possibility of recovering the salmon in the river in the mid-1990s, and they also focused on river recovery in cities worldwide."

    Andy and his group are devoted to giving the river a full make-over. This monumental repair job, supported by approximately $95,000 of funding from the Pacific Salmon Foundation over the past 15 years, has involved recovering the river-habitat of salmon and preventing it from wearing away. Work on the river's final section was completed in October 2016.

    The summer I turned 16, my father gave me a car, which permitted Hannah and me to drive around Tucson whenever we wanted to.

    Hannah was my best friend. "Hannah's amazing," my mother always said. And sure enough, that summer she signed with a modeling agency. She was already doing runway work.

    One day, Hannah and I went to the movies. On the way home, we stopped at the McDonald's drive-through, putting the fries on the seat between us to share. "Let's ride around a while," I said. It was a clear night, moonlight shone over the desert. Taking a turn too fast, I hit a patch of dirt and fishtailed.

    French fries on the floor. An impossible amount of blood on Hannah's face. They took us in separate ambulances. In the ER, my parents spoke quietly Best plastic surgeon in the city. End of her modeling career.

    We'd been wearing lap belts, but the car didn't have shoulder harnesses. I'd cracked my cheekbone: Hannah's forehead had split wide open. What would I say to her?

    When her mother, Sharon, came into my hospital room, I started to cry, bracing myself for her anger. She sat beside me and took my hand. "I almost ended my best friend when I was your age," she said, "I totaled her car and mine."

    "I'm so sorry," I said.

    "You're both alive," she said, "The rest is window dressing." I started to protest, and Sharon stopped me. "I forgive you. Hannah will too."

    Sharon's forgiveness allowed Hannah and me to stay friends throughout life. I think of her gift of forgiveness every time I want to resent someone for a perceived wrong. And whenever I see Hannah, the scars are a symbol of grace for me.
