As we all know, environmental pollution is serious now. Our group wanted to know how much our young people knew about this problem and whether they realized the situation of our environment. So we made a survey of them.
This survey was mainly about many different environmental problems in China and the situation of the polluted environment. What’s more, we also paid attention to the environmental awareness (环保意识) of our young people. In the project, we also designed a questionnaire (问卷调查) to survey the young people in China.
The questions in the questionnaire could be divided into two parts. One was mainly about some knowledge of the environmental problems in China, the other was about environmental awareness.
The results of our questionnaire
Do you know about these problems?
Use the plastic bags
From the results of the questionnaire, we can see our young people’s environmental awareness needs to be raised and they are short of the knowledge of the environment. It’s really worrying.
1．Why did the group do the survey?2．How many parts are there in the questionnaire?
3．Which is known by the most people among the problems?
4．According to the chart, what do 15% of the people sometimes do?
5．What does the data (数据) of the two survey charts show?

y = sin x， x∈R， y∈[–1，1]，周期为2π，函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x， x∈[–1，1]， y∈[–π/2，π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
