Birds whose favorite food is seeds appreciate it when you don't removethe dead flowers.
句中seeds是名词,appreciate是形容词,为何名词后可以加形容词?
Birds whose favorite food is seeds appreciate it when you don't remove the dead flowers.
【答】这里的 appreciate 是及物动词,意思是“感激”、“感谢”,后面可以接名词或者动名词作宾语。它的后面也可以接“it + if 从句”,这个 it 是形式宾语,不可以省略。
