A. why it is that
B. how it is that
C. why is it that
D. how is it that

(答案→)A. why it is thatB. how it is thatC. why is it thatD. how is it that解析：考查强调句的特殊问句和宾语从句的用法：句意：你能解释为什么这学期迟到好几次的原因吗？--对不起但是这是我这个星期第一次迟到。强调句的特殊问句的结构是：特殊疑问词+is/was+it+that….，因为是询问原因的用疑问词why，在AC中选择，根据从句在explain之后，确定这是宾语从句，宾语从句中应用陈述语序，排除C。故A正确。
