One day after school Mr. Tillman found Philo Farnsworth making drawings on the blackboard in the school-room.
“What are you doing?” Mr. Tillman asked with interest. “ What are these drawings?”

“I want to invent things,” Philo answered, “and these are drawings of my first inventions.”
Mr. Tillman smiled to himself, “What is your invention?”
“I have an idea for a way of sending pictures through the air,” The boy answered. “Please just let me tell you about it. You are the only person who can understand what I have done.”
In 1922, even radio was new. The United States had fewer than 30 radio stations. But in 1922, a boy of 16 showed his teacher drawings for television!
In 1926, Philo worked as an office boy in Salt Lake City. Many important businessmen came into the office where he worked. One of these, George Everson , was from San Francisco. Like Mr. Tillman, Everson soon became interested in Philo. The shy, hard-working boy was like other office boys who Everson had known.
One evening Everson asked Philo to have dinner with him. After the meal, Philo began talking about his idea for Television. At first, Everson was not much interested in the invention. He listened only to be polite.
Many years later, Everson wrote a book telling about that evening with Philo. “As Farnsworth talked, he seemed to change,” Everson wrote, “His eyes lighted up , and he was no longer shy.” Talking freely about his invention, Philo Farnsworth was no longer an office boy--he was a scientist.
At the end of the evening, Everson was more interested than ever in Philo. And he was also interested in Philo's idea for television.
After talking with Philo , Everson returned to San Francisco. There he brought together a number of important businessmen . Philo told them about his invention. The men became so interested in the young inventor that they gave $25,000 to help him work on his idea. Philo was only 20 years old, but here was his chance.

A five-day holiday can be very exciting for anyone. But a small thing can also make you feel really bad.

    One sunny day Mr. Li wanted to go to Hangzhou for a trip. He wanted to take a train because he would like to see the villages and rivers along the way. And it was not expensive. After he arrived at the train station, he waited for（等待）a long time. He had nothing to do, so he bought a book and read it. When the train came, he got on the train and sat down. About ten minutes later, a man came up to him and said, “Excuse me, sir. This is my seat.”

  “What?” Mr. Li said, looking at his ticket（票）.

  “Are you going to Chengdu?” the man asked.

  “No, I'm going to Hangzhou,” Mr. Li answered. And then he knew he got on the train by mistake.

   Luckily, he didn't miss the right train. All in all, it was not a good start.

    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 66^th 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.
