If you remove that fish, it puts into motion a whole chain of events.

【翻译】如果你把那条鱼移走，它（指：此举动）就会引发一连串的事件。

网友的问题涉及“宾语后置” 或“词语分隔”。

put ... into motion：

把...付诸行动

将...投入实施

导致；引发...

该句puts 的宾语是a whole chain of events，因相对较长被后置。put 是及物动词，需要接一宾语。宾语因过长或出于修辞需要，被置于状语之后。这种现象叫做“宾语后置” 或“词语分隔”。

动宾结构被介词短语分隔，举例：

She carries over the shoulder of her leather coat a heavy black purse.

When we pass a big building or see an airplane or a car, we might keep in mind that we are looking at the fruits of man’s labour in this tradition.

It is better for you to take with you whatever you need most anytime.
