After they _____ the first super computers in the 1940s, scientists and engineers began to develop ways to create networks.
选项
A、create
B、created
C、have created
D、has created
答案
B
解析
考查动词时态。本句是主从复合句,主句使用了一般过去时(began),其动作“开始开发”在after引导的时间状语从句的动作“创造第一台超级计算机”之后发生,且从句中有表示过去时间的状语in the1940s,因此需用一般过去时。B项created正确。
