六、阅读回答问题
In the past five years, about 2.8 billion school textbooks were sold per year, with total spending of 20 billion yuan, news magazine Outlook Weekly reported.
Zhao Dehua owns a large company recycling resources. He said many college graduates sell the textbooks they’re used for four years at an average price of 1 yuan per kilogram. As these textbooks are mostly used to produce recycled paper, the cost is even higher than that of raw(未加工的）paper.
At present, free textbooks on music, art and science for the nine-year education from primary school to middle school have been reused. But there isn’t a good platform and service supporting system for the second-hand textbook trade, so most of the textbooks end up as waste.
“Every year, second-hand booksellers collect textbooks at a price of about 4, 000 yuan a ton. It is more than twice the price of ordinary waste paper. But the number of people who come to collect second-hand books is still small,” Zhao Dehua said.
“Setting up the system of textbook recycling is good for the environment. Besides, it also helps to develop students saving habits and sense of responsibility,” said Zhu Pin, a head of a school in Jiangxi Province. Up to now, the school has set up a system for reusing the textbooks and it can save a lot of money every year in the next five years.
37．How many school textbooks were sold every year in the past five years
_________________________________
38．What does Zhao Dehua do

39．How do most old textbooks end up

40．How much do second-hand booksellers usually pay for a ton of textbooks

To cut down air pollution, we should take a bus or subway instead of driving. Or we can ride a bike, which is good for health and doesn't cost anything.
Hope there will be less and less air pollution in the future.

Let’s have a writing practice.
Write a short passage about waste pollution according to the questions.
1. What is the problem 2. What causes the problem
3. How should the problem be solved
2. Nowadays, the waste pollution is becoming more and more serious. There is too much rubbish and waste because people are throwing away things every day. And people are also littering in public, which is turning beautiful places into ugly ones.
To solve the problem, there are a lot of things we can do. For example, simple things like bringing a bag to go shopping can help. Besides, we should not use the wooden chopsticks or plastic forks when buying takeaway food. We are supposed to use the ones at home. Last but not the least, remember to throw rubbish into the bins and keep public places clean and beautiful for everyone.
In a word, our actions can make a difference and lead to a better future.
