假設你是紅星中學高三一班的學生李華，為回響綠化祖國的號召，你班四月十二日去郊區植樹，請根據以下四幅圖的先後順序，介紹植樹活動的全過程，給某英文雜誌的“綠色行動”專欄寫一篇以“Green Action in Our Class”為題的英文稿件。 注意：詞數不少於60 提示詞：郊區suburbs April 12 is memorable because our class had a meaningful experience on that day. In the morning, we bicycled to the suburbs to plant trees, talking and laughing all the way. Upon arrival, we began to work immediately. Some were digging holes. Some were carrying and planting young trees. Others were watering . After getting the work done, we put up a board reminding people to protect the trees. Before leaving we took some photos to record our green action. Seeing the lines of trees, we all had a sense of achievement. We feel it’s our duty to protect and beautify our environment.
