Erden Eruc has been rowing across the Pacific Ocean in a rowboat since he left California on July 10, 2007. He has been heading for Australia with only birds, fish, and sharks ever since.

    Crossing the Pacific is only part of his journey. Eruc has decided to go all the way around the world using his own energy. He will row, bike, walk and climb the world without help from any motors(发动机) at all. His plan includes climbing the tallest peak on six of the continents(洲) along the way.

    For the first part of his trip, he bicycled 5,546 miles from Seattle, Washington to Mount McKinley in Alaska and back, walked 67 miles to base camp and climbed 20,320 feet to McKinley's peak. Now in the second part of his adventure(冒险活动), he is rowing to Australia.

    Why would he try to go around the world this way? He explains that he wants to encourage kids to dream their dreams and get to their own goals. He wants to show kids that there might be hard parts along the way, and sometimes they might not even get to that final goal. But they can have adventures and learn a lot along the way.

    When his trip around the world takes him across land, he enjoys meeting people—especially children. He has already visited many schools and shared his story. Eruc encourages all kids to set their eyes on a goal and not give up. He says, "with goals, we will make progress, and we will be farther along than when we started, even if we don't get to some goals. That's called life!"

    Sammy looked out of the classroom window at a bird in a tree. He saw a worm (小虫) in the bird's mouth. "Wow!" he whispered as he looked at the bird eating the worm.

    "Sammy!" his teacher Mr. Maxwell said loudly.

    Sammy jumped and knocked his science book off his desk. Everyone in the class laughed and Sammy blushed. This was the third time today he had been caught not paying attention to the science lesson. It was just so easy to get distracted (分心的) when people read aloud from the science textbook!

    It wasn't that Sammy didn't like science. He loved to learn about machines, Earth and animals. He even thought bugs and plants were great. He wanted to go outside and see how a snake lived. He wanted to watch plants growing from the ground as they did last month. He just didn't want to read about these things.

    Sammy thought Mr. Maxwell would surely understand. "There was a bird with a worm in its mouth..." Sammy began. Then he saw the furious look on his teacher's face. Sammy decided that he had better stop talking before Mr. Maxwell became any angrier.

    What comes to your mind when you hear the word "twins"? Born on the same day? Looking almost the same? Or having the same hobbies? Well, I have a twin brother who was born on a different day from me. We do not look very much alike and we are always interested in different things.

Twelve years ago, my brother, Wayne, was born at eleven fifty-eight on the night of May 28. Five minutes later, I was born一on May 29. Since we were born, I have always been heavier and stronger than Wayne, so people usually think I am the older brother.

    But Wayne is always smarter than L He loves reading and learns many things quickly. He knows a lot about animals, although he does not spend much time with our dogs and birds. He knows e lot about bicycles, but never likes to ride bikes as much as I do.

    Though we are very different, I love my brother very much. I hope both of us can have a happy life in the future.
