Sandwiches are delicious, but do you know how the first sandwich came? An English earl(伯爵)called John Montagu made it three hundred years ago. Montagu was interested in card games. He would play these games with his friends for a long time. He found it too boring to stop his games for meals.

    One day, in the middle of a game, Montagu was served a meal of sliced meat with bread. At that time, Montagu was playing the game that needed its players to cover one card over another. As Montagu looked at both the game and his food, an idea came to his mind.

    He took a piece of bread, put a piece of meat on it and covered that with another piece of bread. Then Montagu could play cards with one hand and eat his meal with another.

    Montagu's friends called the new meal sandwich because Montagu's full title was “the Earl of Sandwich”.

    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.

    He was a single（单一的）father, only living with a 5-year-old son. He was often worried about his son growing up without a mother to look after him.

    One day he went away to work, leaving the child at home. He was worried about the child all the way, not knowing if he was hungry. But his child always told him not to worry. He went home quickly after finishing his work.

    When he got home, the child was already deep asleep. When he took off his hat and was about to sleep himself, he was surprised to find a bowl of noodles under the quilt. He spanked（打屁股） his sleeping son heavily. "Why are you so naughty（淘气的）, making the quilt dirty? Who will wash it?" It was the first time that he hit his boy after his wife died.

    "I don't," the child replied with tears in his eyes. "This is your supper, Daddy." In order to let his father eat dinner as soon as he got home, the child cooked two bowls of noodles: One for himself, the other one for his father. He was afraid his father's noodles would get cold, so he put them under the quilt to keep them hot. Hearing this, the father hugged his boy without saying a word.
