imagineMy grandma still treats me like a child .She can`t im

can't 后面应是动词原形,怎么是can`t imaging
说话人认为已经长大成人了,所以用形容词grown up.如果用现在分词,表达意思不确切.

我想因该可以，因为那时现在式。（still）

My grandma still treats me like a child. She can't imagine me grown up. 其中 imagine 的意思是想象
Yes, image and imagine are two different words.
imagine = 想象 = imagining
image = 影像 = imaging

image and imagine are two different words.
