题目内容
15.His sister left home in 1998,and ________ since.( )A. | had not been heard of | B. | has not been heard of | ||
C. | had not heard of | D. | has not heard of |
分析 他的妹妹在1998年离家,自那之后再也没有人听说过她.
解答 答案:B.
分析句子的内容可知,since后面应该是省略了1998,说明句子的时态要用现在完成时;而句子的主语是His sister与谓语动词hear of之间为逻辑上的动宾关系,所以用被动语态;故选B.
点评 本题考查时态和语态,要了解各个时态的用法并结合具体的语境选择出正确的选项.
