请问一下这个句子的结构,pressing one's palms together and resting one's head on the back of one's hand while closing the eyes as if sleeping means "I'm tired"为什么while后面用closing还有as if后为什么用sleeping?
答
[pressing one's palms together and resting one's head on the back of one's hand (while closing the eyes) (as if sleeping)]
[主语] {宾语}
pressing...和resting...都是用动词主动式来做名词主语.
while he was closing是状语从句,省略he was,所以用sleeping,表明当时正在的状态.
as if he was sleeping,同上,也是省略.
