阅读下面两篇短文，根据所给语境，按要求完成下列各题。
Many provinces, including Jiangsu, Shandong, Shanxi, and Fujian, started a textbook recycling
program at the beginning of the new semester. The program is to cut paper use. ①If all the textbooks are
reused for five years in China, the country can save about 225 million yuan.
Under the program, primary and middle schools give out textbooks to students free of charge. ②The
books will be collected at the end of the semester for future use, so they need to be kept in good
condition.
Getting new textbooks each semester has been the routine (常规) for most Chinese students for
many years, especially in rich places. Many grandmothers make textbook covers for their grandsons or
granddaughters, who come home with their school bags full of new textbooks on the first day of a new
semester. So can students accept the change? At least some students said they could accept the change.
"I like the idea of recycling my textbooks and I will do my best to keep them as new as possible," said
Zhang Muge, a grade two student. ③But some parents don't like this. "Recycled books may carry
germs (细菌) from previous (前任的) users," said a father in Fuzhou city. "I prefer to pay for the new
text books since they are not that expensive."
