無謂語動詞!整句是what most impressed my friends and I as we toured tne mansion was a landscape paintingso vividly realized that we at frist thought it was a window looking out onto a sunit meadow.what most impressed my friends and I as we toured tne mansion這些是what引導的主語was a landscape paintingso vividly這是修飾painting的狀語 realized that we at frist thought it was a window looking out onto a sunit meadow.這句話不懂，怎么又多了realized及后面。這樣就是多了一個謂語動詞。把 realized that we at frist thought it was a window looking out onto a sunit meadow.這句話從你的那一大句話中分開，然后在寫realized的同義句。這是一道sat2013一月的題 答案畫線的是my friends and I錯不知道是為什么realized that we at frist thought it was a window looking out onto a sunit meadow.這句話我真不懂。 你說是my friends and I錯的話那就改i 為me 。impressed后要加賓語 i 的賓格為me 。我也是猜的，畢竟沒看出來！
