合并句子題! can you tell me ?whose backpack is that? can you tell me?whose backpack is black?如果你要把這兩個從句：whose backpach is that? 和 whose backpack is black? 合成Can you tell me? 這個主句的賓語的話,就是：1、Can you tell me whose backpackthat is? 和2、 Can you tell me whose backpackis black ? 原因1,正如你所分析的那樣.2,如果將that 放在 backpack 之前的話,它就作定語,不是表語.因此,在第二句中,black 作主語,whose作主句的賓語從句的引導詞,同時又作backpack 的定語.整句還是陳述句語序.
不知我分析透了沒有,愿與你再探討.
