1. 简单趋向补语

The simple directional complement

“来”and “去” are often placed after certain verbs to act as their complements, showing the direction of their actions. Such complements are called simple directional complements. If the action moves towards the speaker, or proceeds towards the object(s) under discussion, we use “来”：and if the action moves away from the speaker or proceeds away from the object(s) under discussion, we use “来”; and if the action moves away from the speaker or proceeds away from the object(s) under discussion, we use “去”.
If a verb with a simple directional complement has an object, it should be placed between the verb and its complement. To negate the completion of an action, the negative adverb “没（有）” is used. To form the V/A –not—V/A question with this construction, use the affirmative and negative forms of the predicative verb.

V  +  O +  来 / 去

Note: the verb in this type of sentence cannot be modified by the particle “了”; but the particle “了” can be used at the end of the sentence to show that something has already happened. Thus, we cannot say “你回了家去吗？”
