clear和 clearly的区别不仅仅是形容词和副词的区别有时候clear好像也可以当副词来用的样子还有其他区别吗?不行的话帮我把两个的意思详细写出来也好谢谢

clear 清澈的 clear water
显然的 it is clear to us all that
头脑锐利的 clear mind
清除了的 The road is clear of snow now
清白的 确信的+about 净赚的+money
做副词 清晰明了 Speake loud and clear
完全地 一直地 the ship sank clear to the bottom of the sea
clearly
明确地,清楚地
He spoke so clearly that I could hear every word.
显然地,无疑地
He was clearly mistaken
明亮地 明净地
当两者均可表示“清晰地”、“不模糊地”,有时可换用,但是若其前有修饰语,则只能用clearly.如：He spoke loud(ly) and clear(ly).他说得既宏亮又清楚.He spoke quite [very] clearly.他说得很清楚.I saw all that quite clearly.这一切我都看得很清楚.Speak clearly so that they may understand you.说得慢一些以便他们能听懂你的话.
