One day, a farmer was walking along a road with his son Thomas. The father said. “Look! There's a horseshoe. Pick it up and put it in your bag.” Thomas said, “It isn't worth the trouble.” His father said nothing but picked it up himself. When they got to a nearby town, they had a rest. There the farmer sold the horseshoe and with the pennies he bought some grapes.

    It was very hot, and there wasn't a house or a tree where they could have a rest. Thomas felt too thirsty to walk on. At this time. his father dropped a grape on the ground and Thomas picked it up quickly and ate it. After a while, his father dropped another grape and once again. His son picked it up and put it in his mouth.

    And so they went on. The old farmer dropped the grapes and the son picked them up. When Thomas had eaten up all the grapes, his father said to him. “My dear son, if you had bent down early to pick up that horseshoe. It would not have been necessary for you to bend so many times for the grapes, always remember the lesson(教训):  A person who does not worry about the little things

    will find that he can not do the great things.”

    Heroes come in all shapes and sizes. Many heroes are not even human, such as dogs, horses and cats. They are so brave and helpful that human beings are proud of them, too. Lucca, a 12-year-old dog, is a great animal hero. She is a retired US Marine Corps dog. On April 5, 2016 she received the Dickin Medal from PDSA in London, England. And PDSA will provide free medical care for the sick and wounded animals in need. The Dickin Medal was founded in 1943 by Maria Dickin.

    The Medal is the highest prize for animals working in wars in the world.

    Lucca is the first U.S. Marine Corps dog to receive the medal. As a search dog, Lucca's work was dangerous. She was trained to find hidden weapons and explosive devices. According to the US Marine Corps, Lucca protected the lives of thousands of soldiers, and no soldiers were killed while she was going around. She completed over 400 dangerous pieces of work during six years in Iraq and Afghanistan. In 2012, she lost her front left leg in an explosion while working in Afghanistan.

    Lucca is the 66th animal to receive the Dickin Medal. 30 dogs (including Lucca) have got the Medal as well as 32 World War II messenger pigeons, three horses and one cat.

    Today I am going along with Rowan Dougall, a postman in Queensland in the far north of Australia, on his daily delivery（投递 trip. Every day, Rowan sets off with his post bags in the tail of his little plane--not much bigger than a large family car, and flies across one of the wildest places on Earth, Australia's Cape North, to reach the very faraway inland areas called the Outback.

    We fly just 300 metres above dangerous crocodiles(鳄鱼) and snakes. This is one of the longest and most expensive postman trips in the world.  However, a 50-cent stamp not only gets a letter posted to a neighbouring town, it will get it hand-delivered by flying postman to the furthest areas of the Outback. To help with the costs, the plane takes three or four paying local people or tourists, and I am one of them. In the back of the plane, there is a pile of post--envelopes of all sizes, newspapers, and a few parcels(包裹). Somehow I expected this post to look special, maybe to include some hats or cowboy boots, but this looks no more exciting than the post delivered to me in England. I look at some of the names and addresses, wondering about the people who are waiting for these letters and parcels.

    Rowan's route is 2,000 km long, with 15 stops, and I get a chance to meet Sandy, who has just received an order of clothes from a store. "I look forward to this weekly delivery," she says, "but I do miss actually going shopping myself." Rowan is checking the time. There are another ten stops to make before dusk(黄昏). Time to leap back on the plane and up into the air.

    Have you ever ridden a Ferris wheel lately? Can you imagine the flying feeling as you are pulled up to the top and then moved down to the bottom quickly again?

    Today a Ferris wheel is usually 40 to 60 feet tall. That seems very high when you are on the top looking down. But the first Ferris wheel was 264 feet high- taller than a twenty-story building! Can you imagine the view from the top of that?

    The first Ferris wheel was built for the 1893 World's Fair in Chicago. The people who planned the fair were looking for an attraction that would bring people to Chicago. George Ferris handed a drawing of a giant wheel that people could ride on. At first everyone laughed at his strange idea. But Mr Ferris did not give up, and finally the idea was accepted. The ride opened in June of 1893.

    Today's Ferris wheels have 12 to 16 seats, which each carry 2 or 3 people. But that first one had 36 enclosed cars, each holding 60 passengers. When filled, it carried 2,160 people. During that summer in Chicago, about 1.5 million people rode the Ferris wheel.

After the fair, the ride was moved to a nearby amusement park built especially to show off the wheel. In 1904, it was moved again一to St. Louis for the Louisiana Purchase Exposition. After the fair there, the wheel stood unused. In 1906, it was finally sold to a company for scrap metal(废金属).

    Luckily a Chicago bridge builder, W.E. Sullivan, figured out how to make a smaller Ferris wheel that could easily be taken apart and put together. In 1906, he started the company that still makes many of the Ferris wheels used today.

    But, whenever you ride one, remember that it all began with George Ferris's strange idea!
