    Gregg's dream was to travel around the Americas(美洲). He got the idea after he finished a long bike ride. Gregg's friend, Brooks, also liked riding a bike. The two friends talked and made a plan，they would travel from Alaska to Argentina by bike.

    To pay for the trip, Gregg and Brooks worked to save money for a long time. When they were on the road, they often camped outdoors and ate cheaply. In many places, local people opened their doors to the two friends and gave them food.

    On their way, there were deserts, rainforests and mountains. They visited modern cities and ancient ruins. And they made many friends from all over the world.

    Two years later, Gregg finally reached Ushuaia, Argentina in May 2007. (Near Guatemala, Brooks had to go back and Gregg continued without him.)

They both learned a lot about traveling. Here are some of Gregg's suggestions.

Travel light. You shouldn't carry many things with you.

    Be flexible(灵活的)• Don't plan everything. Then you'll be more relaxed and pleased. Be polite. One traveler told Gregg, "Nobody wants to cheat a nice man." It's true.

    His Apple Computer was such a great success that Steven soon became famous all over the world.

    Last weekend, Jake had a lot of homework to do. He finished listening, spelling and reading exercises in the morning. In the afternoon, he added fifteen and twenty—two, and then he got thirty—seven. He added and subtracted until his hand got tired of writing.

    Then he took the bag out to the dustbin.

    Then Jake could have some free time. He decided to play "Star Monsters". He turned on the monsters fighting on the TV screen while his fingers pushed buttons to make them move.

    Jake was tired. He put on his pajamas, brushed his teeth and crawled under the covers.
