9．我想知道为什么鱼睁着眼睛睡觉．I want to know why fish sleep with eyes on．
分析 I want to know why fish sleep with eyes on．
解答 答案：I want to know why fish sleep with eyes on．这里是一个主从复合句，说的是客观事实用一般现在时，主句是I want to know，want to do sth表示想做某事，余下的作为know的宾语从句，是一个特使疑问句，引导词用特殊疑问词why，后加陈述语序，主语是fish单复数同形，这里是复数，故谓语是sleep，后面加上with eyes on表示伴随，故答案是I want to know why fish sleep with eyes on．
点评 这里是宾语从句的呈现，从其三要素考虑，时态，连接词以及语序．
