单选题 The new tenant (in) the apartment was (obviously) both (suspicious) and interested (in) his neighbors.
  • A. in
  • B. obviously
  • C. suspicious
  • D. in


【正确答案】 C
【答案解析】改为suspicious of,形成与interested in并列的结构。(如果suspicious后的介词也是 in,则可将其省去而与interested共用一个介词in,但suspicious后的介词并不与interested后的介词一致,故不可省。)
