Unit 8 A green worldTask Dear Mr Wu, Daniel and I did a survey this Wednesday. Students were asked about their daily habits. Here are the results of the survey. Only 20 students usually take showers for less than 10 minutes, but 35 students turn off the tap when brushing their teeth. Only 15 students recycle empty bottles, but 40 students use both sides of the paper. It is great that most students remember to turn off the lights when they leave a room, but few students take their own bags to the supermarket. The survey shows students are doing a lot to help protect the environment, but there are still many more things they can do.
