With the click of a mouse, a student will
find abundant information from the largest libraries and museums in the world.
Nowadays with the touch of a
button or the click of a mouse,
you can go to largest libraries and museums in the world to get any information
you want.
为啥这句话里，click或touch前面用the，mouse或button前面用a？
以后碰到with的复合结构，尤其后面是of短语的，都是前面那个名词用the后面那个名词用a嘛？
