_____on ten years of observation and study,Professor Wang announced that everyone dreams every night, whether they realize it or not.

A.Basing   B.Based   C.Been based    D.Having based

B

解析： 句意是“基于十年的觀察和研究,王教授聲稱,每個人每晚都在做夢,不管他們是否意識到。此句中如果選A,則理解為是Basing與主語Professor Wang是主動關系,這時Basing后面應該有賓語。本題空格后沒有賓語,我們就該用Based過去分詞形式作狀語,與后面的說法是被動關系。
