Article: My father left me a treasure when he died. It wasn't a big house or a car. It wasn't cash or gold. In the eyes of the world my father died a poor man. He was a simple mechanic who worked hard to support his family. My father's treasure, rather, was in a thousand wonderful memories that he gave me over the course of his life. One particular one stood out in my mind today. I was just a boy playing in the backyard of a friend's house while my father spent the afternoon under the hood of an old car, trying to get it running again. It seemed to take hours and I wasn't sure whether he could bring the ancient car back to life again this time. At long last, though, he closed the hood and turned the key in the ignition . There was a sweet smile of satisfaction on his face as the engine started. There was a twinkle of joy in his eye when he shook his head. And there was a quiet hum of happiness in his voice as we drove back home that day. This memory made a home in my heart and became a priceless pearl for my soul to cherish. Time and time again, my father showed me that a kind life, a giving life and a heavenly life was created one choice at a time. Not all of his choices were the right ones, but most of them were. He did the best he could. He lived the best he could. And he helped to bring out the best in me, too. He once said to me, "It is lucky that all of your choices are driven by love and inspired by joy." As I look back into those memories my father left me, I realize that each one of them inspired me to live and to love. May all of your choices bring memories of happiness to those around you!

Petroleum is a mineral that is a mixture of hydrocarbons. It is an oily liquid, which may be brown, green, or black in colors. The word "petroleum" comes from Greek. It means "rock oil". Crude (, ) oil is petroleum that comes directly from deep in the ground. It is then taken to a refinery. a refinery is a kind of factory to refine oil. At a refinery the crude oil is separated into many parts. From the refined petroleum we get important things, such as gasoline, kerosene, fertilizer, detergents and a lot of other useful things. In fact, there are thousands of such things that we can get. Petroleum really is of great value!

Article: In this day and age when we have a tendency to toss toys that are even slightly worn, it is tough to believe that there is a "hospital" where dolls can be repaired and brought back to their original glory. What is even more amazing is that such a place has existed for a century and is still going strong. Welcome to Sydney's "original Doll Hospital" that celebrated its l00th birthday, on February 22nd, 2013. In 1913, a general store owner in Sydney began importing dolls. However, the rubber bands that held them together would often break. Luckily for him, his brother Harold Chapman Sr., was a good handyman and set aside a little "hospital" area in the store to repair the delicate toys. But when customers found out about this, they began bringing in their raggedy dolls, stuffed animals and even leather goods and umbrellas--starting what would become a family business for many generations. In l930, Chapman's son also, named Harold, relocated the doll hospital and expanded the business even further, by agreeing to repair anything that could be fixed, no matter how big or small. While business was _ , the real boom came in 1938 during World War Two. Faced with extreme restrictions, new dolls and toys became a rarity, and young girls and boys had no option, but to get their existing ones lovingly restored. While it does not have as many employees today, the hospital that is run by his son Geoff Chapman now sits in a spiffy location with a beautiful store-front that features everything a little girl could possibly wish for, from new to lovingly restored, to even extremely rare and valuable dolls. Also in keeping with modern times and dolls, the doctors are now specialists--some focus on bringing back to life modern dolls, while others stick to antiques. And then there are also the soft toy experts and accessory repair experts. Though it may not appear to be, the doctors say their jobs are very interesting given that no two dolls are the same or need the same repairs and that just like medical doctors they have no idea what obstacle they will have to face when they come to work each day. The one advantage? There are no emergency night calls to worry about!
Answer: There are different experts who specialize in different types of toys.
