VP+VPgrammar point · tier 4 · serial verbs (連動): one subject, two acts in sequence
One subject runs two verb phrases back to back, in the order they happen: the first act, then what it is for or what follows.
字源 FORM what the parts do
Two verb phrases stand side by side under a single subject, with nothing linking them. Their left-to-right order is the order of the acts: the earlier or enabling one sits first, the later or purposed one second.
故事 STORY a scene to remember it by
One walker pushes off the planted foot into the next stride. Swap which foot lands first and the path runs somewhere else.

框 · Frame
[subj] [VP1] [VP2]
觸 · Trigger
One person does two things in a row and the second is the point of the first; you want them in one clause, in the order they occur.
序 · The move
1Put the act that happens first, or that enables the other, as VP1.Could the two be swapped without changing the event? If yes, this is not a serial chain.
2Set the purposed or following act as VP2, directly after VP1, with no connector between them.Is VP2 the reason for or the next step after VP1, sharing the same subject?
3Leave out any 而/和/then-word; the bare order carries the sequence.Did a linking word sneak in that breaks the two into separate clauses?
例 · Examples
1我要回家go home (first act)吃飯eat a meal (what the trip is for)了。
和 strings together two things in a list with no order between them; VP+VP strings two acts whose order is the meaning. Reverse a 和 list and nothing changes; reverse a serial chain and you get a different event.
一…就… marks the second act as triggered right after the first across two clauses; plain VP+VP only states the order, with no claim of speed or trigger.
我吃飯回家。 → 我回家吃飯。 (going home enables the meal, so it comes first; reversed it means going home after eating)
我回家和吃飯。 → 我回家吃飯。 (no connector between the two acts; 和 would split them into a flat list)
我要回家去吃飯了。(去 inserted unnecessarily) → 我要回家吃飯了。 (VP2 follows VP1 directly when no separate destination is named)
English needs 'to' or 'and' between the verbs ('go home to eat', 'go and eat'); Chinese sets the two verb phrases adjacent and lets their order do the work.
