山顶 peak summit of mountain top of the mountainhill crest mountainy mountain top登上山顶 reach the summit 山顶空气稀薄。 The air at the top of the mountain is thin. 飞机擦着山顶飞过。 The plane swept the hilltops. 她领先登上了山顶。 She was the first to reach the top of the hill. Clouds have settled over the mountain tops. 那些云彩在山顶上空停留不散. When I got to the top of the mountain, the sun was shining. 我到达山顶时，阳光灿烂。
