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”。
