試題分析：在復(fù)合句中用作賓語的從句叫賓語從句。　1．語序無論主句是陳述句還是疑問句，賓語從句都必須使用陳述語序，即“主句＋連詞＋賓語從句（主語＋謂語＋……）”句式。2.時(shí)態(tài)：1·主句用一般現(xiàn)在時(shí)，從句可用任意時(shí)。2·主句用過去時(shí)，從句用過去某個(gè)時(shí)態(tài)。3·主句用過去時(shí)，從句是客觀真理時(shí)，用一般現(xiàn)在時(shí)態(tài)。3.連接詞，分連接副詞、連接代詞、從屬連詞。連接詞位于主句和從句之間。A項(xiàng)時(shí)態(tài)不正確，BC項(xiàng)語序不正確，D項(xiàng)語序時(shí)態(tài)連接詞都正確，故選D.
