是“whose backpack is this "还是“whose backpack this is "为什么?

是“whose backpack is this 还是“whose backpack this is 为什么? Whose is that backpack?(改为同义句) _______ does that backpack ______ ________? can you tell me?whose backpack is that?合并成一句我的答案can you tell me whose that backpack is我做的答案是错的,我认为宾语从句的从句应该是陈述句子才用的that backpack is 正确答案是can you tell me whose backpac can you tell me?whose backpack is black?两句合成一句我知道从句应该变成陈述语序,回答这个从句的陈述句子是backpack is black所以合成can you tell me whose backpack is black.但是这个句子的答案我就不理解了ca Whose backpack do you think ____?A.THIS IS B,IS THIS 那为什么Whose backpack do you think ____?填is this 合并句子题!can you tell me whose backpack is that?can you tell me?whose backpack is black?怎么分析出来的第一句是对表语提问,第二句是对主语的定语进行的提问?因为分析不好所以不会合并第一句.我知道宾 It is my backpack _your backpack Your backpack is where is backpack It is in the backpack? It is in the backpack? Is this Mike is backpack的答语是yes this is吗 whose watch is that的意思是? whose+jacket+is+this是甚么意思 That is a backpack in English .(划线提问)提问backpack This is a backpack.（对.backpack提问） 连词成句,is, her ,that,backpack.｜ .this,your,is,pencil ,jane.是两个问题
