题目内容
13.It's not your turn yet.Please wait on the chair over there until you _______.( )| A. | are calling | B. | have called | C. | are called |
分析 现在还没有轮到你.请等在那边的椅子上,直到有人叫你.
解答 答案:C.考查被动语态.句意"现在还没有轮到你.请等在那边的椅子上,直到有人叫你.".A现在进行时态.B现在完成时态.C被动语态.结合语境"现在还没有轮到你.请等在那边的椅子上,直到有人____你.",主语you是动作call的承受者,因此这里用一般现在时态的被动语态,结构式is/are/am+动词的过去分词.主语是you,用be动词are.call的过去分词是called.答案是C.
点评 被动语态表示主语是动作的承受者,被动语态由"be动词+及物动词的过去分词"构成,be动词的单复数要与主语的单复数保持一致,还要注意时态及过去分词的变法.
