单选题
The Internet has been around for an almost equal amount of time as most forms of media, but only recently________a popular way of retrieving information.
A、
has it become
B、
it has become
C、
it becomes
D、
does it become
【正确答案】
A
【答案解析】
空白处前面有only,因此句子使用部分倒装。而recently表明动作从过去到现在,强调对现在的影响,因此时态上使用现在完成时。现在完成时的部分倒装将has放到前面,其他成分顺序不变,故选A。
