第045句
In fact, it is difficult to see how journalists who do not have a clear grasp of the basic features of the Canadian Constitution can do a competent job on political stories.
译文:实际上,很难理解那些对《加拿大宪法》的基本特点缺乏清晰了解的记者如何能胜任政治新闻报道工作的。
点睛:it为句子的形式主语,真正的主语是不定式结构to see...。how引导的是see的宾语从句,其中who引导的是以journalists为先行词的定语从句。grasp在句中作名词,意为“领会,掌握”。
