Teacher: So, how was your vacation, Karen?

Karen: It was great. I had a vacation with my friends in Hainan last winter. There were beautiful beaches and blue sea water. It was sunny and warm. We stayed there for a week. We went swimming every day. We played beach volleyball together. We ate seafood, too. We felt very relaxed.

Teacher: How about you, Brad?

Brad: I went to Beijing with my parents on vacation. The weather was fine and the trip was happy. We spent five days in Beijing. We visited Tian'anmen Square and the Palace Museum. We also went shopping. The shops were crowded. We ate in some Chinese restaurants, too. The food was cheap and delicious. The Chinese people were very friendly. We had great fun in Beijing.

    A group of high school students from the United States has planted hope by cleaning up an empty lot(一块地) in their neighborhood.

    The students are from Buchtel High School in Akron, Ohio. The empty lot, which is owned by a 1ocal bank, was filled with grass and poison ivy(毒葛). As a project for the school's biohealth(生物健康) class, eight students decided to turn the empty lot into a space that will improve the mental(心里的) and emotional(情感的) health of people who live near it.

    They first came up with a design, did research and created 3D models of their plans. Ideas were then presented and the school leaders picked the winning plans. Finally, the students brought those plans to life.

    Now when you walk into the lot, you can see a wood walkway leading to a purple iron bench. A few beautiful plants are already in the ground. There is also a hopscotch(跳房子游戏) board that is painted bright blue. A wall painting with the words "Love" and "Peace" has taken shape on a back fence, decorated with the students' handprints. The rest of the fence was painted grey to cover plain wood.

    The students said they painted the bench purple because they found that purple has a comforting feeling for people. They thought kids could go there and sit together, communicate with each other in peace and stay out of trouble.

    As for the hopscotch board, it was set up for a group of eight to ten school-age kids who lived in the neighborhood but had nowhere to play.

    It gives the neighborhood a little hope and a little beauty, "said Lyle Jenkins, a member of the Neighborhood Network." A lot of people love the neighborhood and have great hopes for things getting better.
