单词 change 和exchange 有什么区别做动词时 两词都一样 如何区别它们呢? 用它们造个句子出来谢谢各位~

change, 意为“变化，改变”
exhange,意为“交换”，二者词义不同
change,e.g.: She has been changing her dresses for 2 hours to find the perfect piece.
exchange,e.g.: I would like to exchange my life with yours, you have the most precious thing in the world, so take care of it!

change是‘改变”的意思，而exchange是‘交换”的意思
We can change the world.我们能改变世界。
We shuold exchange our thoughts with each other.我们应该互相交换意见。

change做动词时,有三种意义：1.更换（衣）；掉换.例如：
He changed his clothes before going out.他出门前会换衣服.
Where do we change?我们在哪里换车?
2.兑换,互换.（此时,change=exchange,无区别）例如：
I changed places with her.我与她互换位置.
/I exchanged places with her.
3.改变；变化.例如：
The wind has changed from north to east.风向由北转东.
