问题 Government cannot operate effectively ___________ it is free from such interference.A.so long asB.so thatC.unlessD.because

选项 A.so long as
B.so that
C.unless
D.because

答案 C

解析 考查连词辨析。句意为“除非政府摆脱这种干扰,否则就不能有效运作”。unless意为“除非;如果不”,相当于if…not,引导条件状语从句。其他三项,so long as“只要”,so that“因此;以至于;以便”, because“因为,由于”,均不符合题意。故选C。
