I turned around to see an old woman.
“Are you new to this neighborhood？” I explained that I was，__13__， new to the entire state.
“My name is Ina Thorne. Have you got used to life in the __14__？ It must be quite a__15__after living in Boston.”

答案 A [此处填的find不是表示“发现”，而是表示“感觉”，又如：How do you find your new job? 你认为你的新工作怎么样？]
17．A.why B．when C．how D．where
答案 B [句中的vastness 意为“宽广”或“空旷无际”。句意：这种宽广就是当你站在山上眺望其下沙漠的情景。]
18．A.prove B．guess C．sense D．expect
答案 C [此句的大意是：当你站在山顶上眺望这一片沙漠的时候，与这个世界相比，你会感觉到你自己是多么的渺小。sense 在此表示“感到”，其余几个动词填在此处均讲不通。]
19．A.However B．Otherwise
C．Therefore D．Meanwhile
