问题描述:

the computer,woring very fast ,_data at the speed of light A has handled B handled Chandling D handles 选什么 为什莫
考的是甚么呀 时态吗

选D
现在分词短语working very fast是修饰computer的,是插入语,分析句子时可以去掉.
句子的主干是the computer handles data at the speed of light,电脑以光速处理数据.
这说的是一般的情况,所以用一般现在时.
A项是现在完成时,与题意不合.
B项是一般过去时,与题意不合.
C项是现在分词,作谓语时要与助动词is接合起来用.不过即使加了is,还是与题意不合.
