题目内容
15．Mom，someone _________．Please pick up the phone．（ ）| A． | has called | B． | is calling | C． | will call | D． | was calling |
分析 妈妈，有人打电话．请接电话．
解答 答案：B
根据Please pick up the phone"请接电话"可知此处强调上文某人正在打电话，句子描述的是现在正在发生的事情，故用现在进行时态，该时态的结构为is/am/are+现在分词，根据主语someone是不定代词，谓语动词用单数，故动词be用is，call的现在分词为calling，套用结构，故选B
点评 结合语境可知该句描述的是现在正在发生的事情，故用现在进行时态，其结构为is/am/are+现在分词，套用结构，即可选出正确答案，在本题中还要注意someone，anyone，no one，everyone，something，nothing等复合不定代词作主语，谓语动词用单数
