题目内容
16.Much time __________ sitting at a desk,office workers are generally troubled by health problems.( )A. | being spent | B. | having spent | C. | spent | D. | spending |
分析 句意:因为大部分时间都坐在办公桌前,所以办公室职员一般都受健康问题的困扰.
解答 考查独立主格结构.由句子结构可知,分词的逻辑主语much time与主句主语office workers不一致,所以是独立主格结构.逗号后为主句,逗号前为独立主格结构作原因状语.time与spend是被动关系,故填spent.
点评 解答此类题目首先要分析句子结构找出主句,同时要注意主句的主语与分词的逻辑主语是否一致,如果不一致,则为独立主格结构.然后再分析分词的逻辑主语与动词的主被动关系,主动用doing,被动用done.
