Read the passage 12（p36)
Our environment is changing for the worse, so it is time for us to go green. Here are some simple steps to take at home.
We can save water by taking shorter showers and turning off the tap when we brush our teeth. In order to save power, we should turn off the lights when we leave a room.
Some other good habits can help reduce pollution too. We should not use plastic bags when shopping. Recycling is also a good way to help reduce pollution. We should separate waste into different groups so that it can be recycled.
Follow these small steps, and you can make a big difference to the Earth!
