Kaitlin Riffel's dream to end poverty（贫困） started when she was visiting her father，who worked for the homeless．

    "I never realized there were people in the world who didn't have a home or food before，"said Kaitlin，who is now sixteen．"I knew there was something I had to do about that．"

    At age eight，she started raising money to build a playground．"It took me two years，"Kaitlin said．"We started small．We wanted to do something to make a difference．"

    In 2014，When Kaitlin was thirteen，she visited Central America，and saw people going hungry and families living in houses made of cardboard．That year，we set Kids on a Mission，which has helped hundreds of people there．

    "The rooms were smaller than my bedroom，but there would be eight people living in each one，"Kaitlin said．"We also got to see the dirty rivers that those people were drinking out of．"

    Providing clean drinking water，food and clothes for people living in poverty is now an important task for Kids on a Mission．"This young lady is changing the hearts of people，and also changing the world，"said the headmaster of Kaitlin's school．

    Do you know any 9-year-olds who have started their own museums? When Theodore Roosevelt was only nine, he and two of his cousins opened the "Roosevelt Museum of Natural History". The museum was in Theodore's bedroom. It had a total of 12 specimens. On display were a few seashells, some dead insects, and some birds' nests. Young Roosevelt took great pride in his small museum.

    Born in New York in 1858, Theodore Roosevelt was not always healthy. "I was a sickly boy", he once wrote. Roosevelt had a health condition called asthma. He often found it hard to breathe. Instead of playing, he watched nature and then read and wrote about it.

    Roosevelt's interest in nature sometimes got him into trouble. Once, his mother found several dead mice in the icebox. She demanded that the mice be thrown out. This was indeed "a loss to science", Roosevelt said later.

    Because Roosevelt was often sickly as a boy, his body was small and weak. When he was about 12, his father asked him to improve his body. Roosevelt began working out in a gym. He didn't become strong quickly. But he did decide to face life's challenges with a strong will. That determination stayed with Roosevelt his whole life. And eventually his body did get strong. As an adult, he was an active and healthy person. He enjoyed adventures, and he loved the outdoors.

    A toy company named the teddy bear for Theodore "Teddy". After knowing that, Roosevelt refused to shoot a baby bear while hunting.

    In 1900, at the age of 41, Roosevelt was elected Vice President. A year later, President McKinley, was shot and killed. Roosevelt became our 26^th President. At 42, he was the youngest leader the country had ever had.

    After returning from her round trip, the angry woman stood outside the ticket office of the station. "The railway owes me 12 pounds," she said to Harry Jenks, the young man working at the office. "You sold me a ticket for May 22nd, but there was no ship from Jersey that night. So my daughter and I had to stay in a hotel. It cost me 12 pounds. "

    Harry was worried. He remembered selling the woman a return ticket. "Come into the office, Madam," he said politely. "' I'll just check the Jersey timetable for May 22nd." The woman and her little girl followed him inside. She was quite right, as Harry soon discovered. There was no sailing on May 22nd. How could he have made such a careless mistake? He shouldn't have sold her a ticket for that day. Wondering what to do, he smiled at the child. "You look sunburnt(晒黑的) , "he said to her. "Did you have a nice holiday in Jersey?"

    "Yes," she answered, shyly. "The beach was lovely. And I can swim too!"

    "That's fine," said Harry. '" My little girl can't swim a bit yet. Of course, she's only three…"

    "I'm four," the child said proudly. "I'll be four and a half."

    Harry turned to the mother. "I remember your ticket, Madam," he said. "But you didn't get one for your daughter, did you?"

    "Er, well..." the woman looked at the child. "I mean...she hasn't started school yet, she's only four. "

    "A four- year- old child must have a ticket, Madam. A child's return ticket to Jersey costs...let me see.13.50 pounds. The law is the law, but since the mistake is mine."

    The woman stood up, took the child's hand and left the office.

    One night a patient went fishing in another man's boat outside Albert Smith's hospital. The owner of the boat thought he should get all the fish from the patient.

    Dr Smith said to the boat owner, "You are right because you didn't allow him to use your boat. But you are wrong because you are careless and lazy. You seldom(很少) put your boat in a safe place and fasten it with a lock. Because of your laziness you were asleep on this moonlit night instead of making use of the good time to fish. "

    He turned to the patient, "But you are wrong when you took the boat without asking the owner's permission(允许). You are right because you are not so lazy as he is, and you did not want to let the moonlit night go by without making use of it. "

    Dr Smith divided the catch(捕捉物) among the patient, the boat owner and the hospital .

    In 1826, a Frenchman named Niepce needed pictures for his business. But he was not a good artist. So he invented a very simple camera (照相机).He put it in a window of his house and took a picture of his garden. That was the first photo.

    The next important date in the history of photography (摄影术) was in 1837. That year, Daguere, another Frenchman, took a picture of his reading room. He used a new kind of camera in a different way. In his picture you could see everything very clearly, even the smallest thing. This kind of photo was called a Daguerreotype.

    Soon, other people began to use Daguerre's way. Travelers brought back wonderful photos from all around the world. people took picture of famous buildings, cities and mountains.

    In about 1840, photography was developed. Then photographers could take picture of people and moving things. That was not simple. The photographers had to carry a lot of film and other machines. But this did not stop them, for example, some in the United States worked so hard.

    Mathew Brady was a famous American photographers. He took many picture of gread people. The picture were unusual because they were very lifelike(栩栩如生的).

    Photographers also became one kind of art by the end of the 19th century. Some photos were more just copies of the real world. They showed and feelings, like other kinds of art.
