My mom isn't fancy like other moms.They wear fancy clothes and drive fancy cars. My mom wears her gardening clothes when she walks me to school.　

When fancy moms laugh，their laughs sound soft and whispery. You can hear my mom's laugh from down the hall. I show her how to laugh quietly and she practices. But before long she starts laughing even harder than before.

 At the talent show，my mom cheers loudly，“Bravo，everyone！Bravo！”instead of clapping politely the way fancy moms do.

For our class hike（徒步旅行），parents are invited. At breakfast I go over my rules for Mom，“Please don't whistle. Don't laugh loudly. No clapping. And stay in line.”

 The other moms show up wearing fancy jackets and sneakers. My mom wears cutoffs，a floppy straw hat，and her old hiking boots.

We hike along，all in a line. Soon Mom starts to whistle her hiking songs，She'll Be Coming Round the Mountain.I shake my head at her. She stops and whispers，“Oops. Sorry，Jane.”

 We keep hiking. Everything is perfect until…

 Our teacher，Ms. Steele，stops and points，“A snake！”All the moms hold their kids hands and back up，except my mom.“Watch out！It might be poisonous（有毒的）！”Ms. Steele says.

 The other moms shuttle back some more. However，my mom steps forward and says，“Hmm. Let's see what kind it is. Nope，it's not poisonous.”

 I shut my eyes.I know what's coming next. Mom makes a sudden attack.“Got it！”she says. The other moms scream，not sounding fancy at all.

Kids gather around as Mom examines the snake.“It's OK to touch，”she says.

 Everyone's too scared，but I go first.“snakes aren't slimy，”I tell them. Right away，others line up. A couple of the fancy moms come up to touch the snake's tail.

 Later，Ms. Steele tells us to draw our favorite part of the hike. After a while，I look around quickly. Everyone's picture is of Mom and me with the snake.

 As we hike back to the bus，I squeeze Mom's hand.“I'm glad I didn't tell you my don't-catch-snakes rule.”She smiles. But soon，she's whistling her hiking songs again！

 I start to make her silent，then stop. Instead，I take a deep breath and sing out too. Everyone joins in，even the fancy moms.

    The USA is the fourth largest country in the world in size after Russia, Canada and China. The population(人口) of the USA is the third largest in the world.

   The Mississippi River is the longest river in America. It's over 6,000 kilometers long. The Mississippi River has been called the "Father of Waters" or "Old Man River". The most important lakes in the United States are the Great Lakes. They are Lake Superior, Lake Michigan, Lake Huron, Lake Erie and Lake Ontario. All of them are between Canada and the United States except(除了) Lake Michigan.

   Let us talk about American education(教育). There are two kinds of schools in the United States: public schools and private schools. Most children go to public schools. Their parents do not have to pay for their education. If a child goes to a private school, his parents have to pay for their schooling. Children start school when they are five years old. Most students are eighteen years old when they leave secondary(中级) schools.

    One of the best-known American writers of children's books is Alfred Strong, or Doctor Strong, as he is better known to readers everywhere．Now, an art show called "Doctor Strong From Then to Now" is travelling around the United States．The pictures and drawings show the history of Doctor Strong．

    Doctor Strong first became famous almost fifty years ago when his first children's book was published (出版)．Since then, he has written forty—five books that have been sold more than one hundred million copies around the world．

    Doctor Strong's books are known for their easy use of words and colourful, hand drawn pictures．These drawings bring life to his imaginary creatures, The Cat in the Hat, Horton the Elephant, The Grinch Who Stole Christmas, and hundreds of others．

    The San Diego Museum, in California, organized the art show．It included about three hundred Doctor Strong's early drawings and some of his writings．

Most of Doctor Strong's books, although written in a funny way, have serious messages．For example, in McElligot's Pool, he describes the danger of pollution．He discusses the arms race (军备竞赛) in The Butter Battle Book, written in nineteen eighty four．

    Doctor Strong says he never planned to write stories just for children．He says he writes stories that interest people of all ages．He says he uses easy words so that everyone, even a child, can understand．

    Thomas Alva Edison is one of the greatest inventors of all times. One of his most famous achievements is the electric light. He tried thousands of times to make a long lasting light bulb (灯泡). Although the light bulb is not his invention, he is the only one to have made such a successful light bulb. Many people remember him for the invention of the electric light. He held a lot of patents (专利权) worldwide. Many of them were approved (批准) in USA.

    We can find his inventions in many fields. In fact, many of the advanced inventions were based on his ideas. He invented a phonograph (留声机), a film picture camera, a ticket recorder and so on.

    Edison was not a good student at school. But he loved to do new experiments. When he was still a child, he built his first lab to perform his experiments.

    An amazing story of Edison's childhood is that he almost made his servant die. Edison used to think that birds ate insects and these insects might make them fly. So, he collected these insects and blended them to make juice. He then let his servant drink the juice. After drinking the juice, the girl lost her sense. But luckily, she was saved.

    Bob was only seven years old. One night Bob was at home alone while his parents were out for a party. He had often stayed alone before, so he wasn't afraid. As he waited for his parents to return home, he watched a film on TV. His eyes became heavier and heavier as time passed by.

    Suddenly Bob's eyes opened wide- what was the sound in the next room? Bob heard the window being opened slowly. For a minute, Bob was so frightened that he could not move, and his body felt like ice. He knew that he couldn't lose his head and began to think of the things he could do.

    Again he heard the sound of someone trying to climb into his home through the window.

    Bob's drums were standing in the corner near the TV. "Wait, maybe there is something I can do," thought Bob. He beat his drums as hard as he could. The sound was so terrible that Bob surprised even himself. He also surprised the man in the window, who ran away as fast as possible. How clever he was!

    Growing up in the US, I always wanted to know about another culture. The chance came when I was 15. After a few months of planning and preparing, I was ready to spend the second term of my first year of high school as an exchange student in Australia.

    The city I stayed in was Perth, Australia, and it is the fourth largest city of Australia. When I arrived at the airport, the family I would live with were already waiting for me there, and the new school term would start in only five days. The school I attended was very different from my school in the US. In the school we had to wear the uniform, and we were not allowed to wear bracelets (手链) or necklaces(项链). I was quite uncomfortable at first, because I had never been to a new school— even in the US. Everything went smoothly, though. The teachers were welcoming and the students were friendly.

    The most memorable time of my term abroad was with other international exchange students. We traveled around Australia during the breaks. The few weeks we spent together were filled with amazing activities. At the end of our stay in Australia, we had three weeks to share our stories and help each other. Our last day together was filled with tears. We packed our things, exchanged e-mail addresses, and got together to say goodbye.

    I really have learned a lot from my exchange experience.
