So we didn't get wet里面的get是系动词。
Do you get happy在语法上是对的，但在意思上显得很奇怪。因为get作为系动词表示的意思是“变成怎样”（暗含着原来不是这样的意思），所以get happy表示“原来不开心，之后变得开心”的意思
动词get的用法与搭配如下：
第一种用法：当用于get加名词加宾补时，该宾语补足语可以是：
1、不定式，其意为使什么做某事，具有使役性；
2、现在分词，其意为使什么开始起来，或处于某种状态；
3、过去分词，表示被动关系；
4、形容词，意为使什么变成某种状态；
第二种用法：当用作连系动词是，表示状态的变化，其后所接表语可以是形容词，过去分词，不定式和现在分词。
当get需要宾语＋宾语补足语的时，意思是“使，令”。
1、get +不定式

2、get +现在分词
You should get your friend helping you你应该说服你的朋友帮助你。
3、get +过去分词
