He felt sweat on his forehead，but he took the violin from the wall as calmly as if he were a welcome visitor.



as calmly修飾哪個？as if是連接詞嗎？

calmly為方法副詞，修飾took，為方法狀語。

as if為連詞，一般單獨引導方法狀語從句。但這個句子比較特殊，as if與前面的as calmly 呼應，構成了as...as if...的特殊結構，這樣的情況比較少見。此時as if并不是引導方法狀語從句，而是引到比較狀語從句，呼應as calmly.

其實as if= as he/it would if

所以，這個句子中，as后省略了he would.

He took the violin from the wall as calmly as if he were a welcome visitor.

= He took the violin from the wall as calmly as he would if he were a welcome visitor.

他就像一個受青睞的訪客那樣鎮靜地從墻上拿下小提琴。
