[范文]Green Action in Our ClassApril 12th is memorable because our class had a meaningful experience on that day. In themorning, 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 trees. Others were watering them. 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 all think it's our duty to protect and beautify our environment.考点探究互动探究·能力备考Ⅰ.词汇短语过关1．total adj. 总的；全部的；整个的n．总数；合计v．总数为；合计为totally adv. 完全地；整个地in total 总共；总计(＝totally)a total of 总数；总共(修饰名词复数时，谓语动词用复数)the total of...(谓语动词用单数)total up ＝add up算出总数total (up) to＝add up to总额为[即学即练1]—What is ________________________ these books？这些书的全部费用是多少？—It cost me __________________ of 500 yuan.___________，it cost me 500 yuan.The cost ________________ 500 yuan.这些书总共花了我500元。
