问题 For workers in small firms employment ______ are very rare, working hours are longer and safety records poor.
选项 A、guarantees
B、reservations
C、securities
D、assumptions
答案A
解析 语义连贯题。所填词和employment搭配，并和working hours，safety records是并列关系，[A] guarantees“保障，保证”符合句意，所以[A]为答案。[B] reservations“限制，保留”；[C] securities“安全”和safety重复；[D]assumptions“假定，设想”。
