【简答题】
阅读短文,根据要求完成下面各小题。 Hi, my name is Christina Baum. I'm a fourteen-year-old German student. I'm writing to tell you about an experiment we are doing at school with our science teacher. At the beginning of this school year, Frau Keller showed us films and we read articles about problems in the environment. One day she said, 'I want to know what you think. Please don't tell me what we should do or must do. (3) Tell me what each of you will do to protect the environment .' She asked us to choose a topic, make a weekly plan and tell the class about it. Then we had to do things to be 'green' and write a report about our success. Some students said that they thought it was impossible for a single person to contribute to the protection of the environment. Someone else said that scientists should work harder to find new ways to produce energy. Frau Keller said that it is everyone's job to care for the health of the planet. (4) After the first week, everybody in class was excited about the project and wanted to continue to improve their results. Someone suggested telling the other classes in the school. Now all 768 students at Hermann Stein School are working on the project. At the end of the year, our class will write a report about what we have done. (5) 下星期我将会考虑怎样不会浪费水或者污染水。 I'm planning to try and use less water every day, and also not use so much of the things that make it dirty. Every time I turn on the tap (水龙头) I must think about how much water and soap I use. A.根据短文内容简要回答问题。 1.
