Besides breathing, there are two other ways you can produce CO₂. First, you can do it directly, by driving a car or using a gas stove. Second, you can do it indirectly, by buying or using products that produced CO₂ when they were made. Generally, you should make your carbon footprint as small as possible. For example, you can use public transport instead of a car, or you can walk or cycle. 1. What is a carbon footprint? A. The total amount of CO₂ you produce in a year. B. The total amount of oxygen you breathe in a year. C. The total amount of water you use in a year. D. The total amount of rubbish you make in a year. 2.

Using plastic bags. 4. Which is an indirect way to produce CO₂? A. Driving a car. B. Using a gas stove. C. Breathing. D. Buying products that made CO₂. 5. What is the main idea of the text? A. How to produce more CO₂. B. What a carbon footprint is and how to reduce it. C. How to drive a car. D. How to use a gas stove. 四、语法填空（共 10 空，每空 1.5 分） 阅读短文，在空白处填入 1 个适当的单词或括号内单词的正确形式。 Your carbon footprint is the total amount of CO₂ you 1. ______ (produce) a year.
