1,Latest researches show children ___ with high levels of air pollution during their first year of life run a greater risk of developing certain diseases.A,having been associated B,associated B.请问老师为什么?那么A为什么不对呢?请老师从语法的角度详细解释,
have been 是完成时态,如果句子里提及一个时间点,而某动作发生在该时间点之前,则需要用完成时态.我们分析一下你所给的句子,children( ___ with high levels of air pollution during their first year of life )是从句的主语,其中括号部分是用来修饰children的,这里是associated这个过去分词作定语修饰children,并不是为了强调associate这个动作发生在某个时间点之前哦.
