The sun makes the earth hot, but the air over the water stays cool.The hot air over the earth goes up , and then the cool air over the water moves in and takes the place of the hot air.When you are near a lake , you feel the cool air when it moves in.

请问句中的 move in 什么意思？在文中怎么翻译呢？谢谢老师指点。

老师答疑

曾老师：

句意：当你靠近湖泊或海洋时，你会感觉很凉爽。这是为什么呢？太阳使地表变热，但是水面上的空气却仍然很凉爽。地表热气上升后，水上凉爽的空气移动到了热空气原来所处的位置。所以当你在海边或湖边时，冷空气移动，你就感觉到它了。

分析：句中的 move in 是“进入到......”的意思。即：The cool air moves into the place where the hot air once stayed.

z老师：

it moves in

=the cold air moves in

=the cold air moves in to fill the space where the hot air stayed

=the cold air moves in to fill the space where the hot air stayed, which now has been going up because of the heat from the sun.
