Conversation One
19．D综合推断题。结合听力材料，特别是对话开头提到的old book...a lot of pages are turning brown and becoming brittle可以推断，对话谈论的是书的腐烂问题，所以D正确。
20．B综合推断题。女士认为用木材制纸时要往里面加一些化学制品和酸性物质以让纸变白，而男士说最终腐蚀纸张的就是这些酸性物质，由常识可推断出这类酸性物质也应是化学制品，即男士认为书籍的腐烂是由化学制品造成的，故选B。
21．C信息明示题。男士说books have been made from wood pulp only since the 1850s，即19世纪50年代以前的书不是由木浆做成的，所以C正确。
22．C同义替换题。女士最后说的get back to my project与选项中continue her research同义，所以C正确。
