environment/world?
The environmental pollution is worse and worse today. Water is polluted and clean drinking water can‘t be available to many people. Meanwhile, trees are being cutting down. In addition, white rubbish can be seen everywhere. What‘s worse, some factories are letting off poisonous smoke to the sky, causing air pollution.... People's health has been greatly affected and many people died of diseases.
As middle school students, we are supposed to spare no effort to protect our environment. First, we can save as much energy as possible. For example, we could remember to turn off the lights when leaving the house and turn off the tap after washing. Second, try to recycle wastes such as old newspapers, bottles and cans. Third, we can plant more trees to make our environment greener and cleaner.
In a word, the environment is very important and it‘s our duty to protect it. Please join us and take action. 四、【习题训练】 A组 单项填空
