Repeating with no result
- With thinking and talking, it often means "over and over, without getting anywhere": I我think想(here)来think想(there)去,after all还是decided决定not不(there)去(completed / change)了。 — "I thought it over and over and decided not to go after all."
- they他们variant of 说说(here)来variant of 说说(there)去after all还是that那几句话。 — "They kept going round in circles saying the same things."

想来想去 + decision.
Same verb, one syllable
- Use the same verb in both places: walk走(here)来walk走(there)去, not walk走(here)来run跑(there)去.
- It describes a repeated activity, so it rarely takes a result complement: walk走(here)来walk走(there)去, not walk走(here)来walk走(there)去to finish完.
Which is correct?

In verb + 来 + verb + 去 the same verb repeats to show movement back and forth: 他走来走去 “He paces up and down.” Mixing two verbs or adding 了完 breaks the pattern.
Versus back and forth来回
- back and forth来回 + verb also means back and forth: he他in在the door门口back and forth来回walk走.
- back and forth来回 can be a noun: 一个back and forth来回 — "a round trip".
he他at在the door门口back and forth来回walk走。
一个来回 means “a round trip”.

True. 来回 can be a noun meaning “a round trip”: 一个来回要两个小时. As an adverb it means “back and forth”.
Recap
- V(here)来V(there)去 = do repeatedly, back and forth (walk走(here)来walk走(there)去); with think想 / variant of 说说 = over and over.
- Same verb twice; back and forth来回 + verb is a near equivalent.

Your dog can't settle before the storm and keeps pacing around the living room. Close the examples. Say a Mandarin response, then write it in Chinese. Explain briefly in English what the lesson’s pattern adds. Compare with the model, then change one detail and try again.
This is supported productive practice. Compare meaning and structure; your answer need not copy the model. A partner or teacher must hear the spoken response to comment on pronunciation.
