问题 At first the ______ of color pictures over a long distance seemed impossible, but, with painstaking efforts and at great expense, it became a reality.
选项 A、transaction
B、transmission
C、transformation
D、transition
答案B
解析 近形近义题。四个选项拼写形式非常相似，但意义差别很大。选项[A]“交易，业务”；选项[B]“播送，传播”，一般指传播图片、信息、数据等；选项[C]“转变，变革”，一般指内在的、彻底的变革；选项[D]“转变，过渡”，一般指过渡的过程。根据题干，这里说的是长途传送图片，选项[B]符合题意，是答案。
