Chinese permits placing verbs immediately next to one another. In fact this is observed when there are more than two verbs, especially if some of them are auxiliary in nature (e.g. 去, 來).
(1.1) 去 幫忙 做 家務 吧。 Go help do chores.
(1.2) 我 答應 來 幫忙 做 家務。 I promised to come help do chores.
are all grammatical.
2. V+着 as a verb
Only some verbs can have 着 ...
