1. It shows the power of west wind over the sea by describing its power over the waves.
2. It shows the power of west wind over the earth by describing its power over the leaves.
请问：这两句中的over the waves和over the leaves分别的意思是？
over 的本义是“在...之上”，用在“职位、权力、影响、成效”等名词之后，表明对over 之后的名词带有“超越、支配或控制”的意味，表示“凌驾于之上”。你的句子是power，说明power 对over之后那个名词具备支配用途或控制权。又如：
God has absolute power over all. 上帝对万物有绝对控制权。
My power over you shows stranger, stranger! 我的力量在你周围看上去愈加强大!
He has little control over his emotions. 他控制不住我们的感情。
The governments control over the newspapers has loosened in recent years. 近年来政府对报纸的控制已经变松了。
His parents no longer have any real influence over him. 他的爸爸妈妈对他不再有任何真的的约束力了。
He has a strange influence over the girl. 他对这女生有出奇的影响力。
