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 词汇题。这是一道近形词辨析题,transmission表示“播送。发射,传动,传送,传输,转播”:transaction表示“办理,处理,执行,事务,业务,交易”,如:All transactions,from banking to shopping,willbe performed electronically.所有的活动,从跑银行到买东西,都可通过电脑来完成。transformarion意为“变化,转化,改适,改革,转换”;transition表示“转变,变化,过渡,变迁”。
