1。The pattern ''-기 전에'' ; before doing（。。。之前。。。）

The word ‘전’ is a noun meaning “time before” or “place in front” and ‘-에’ is a marker meaning “at, in, on”. So the pattern ‘-기 전에’ is used to express of ‘before something happens’. This pattern is always used with verbs, and the subjects of the two clauses can be either the same or different.

2。The connective ''-고'' ; and（连接词尾）

This connective ‘-고’ is used to link two clauses in coordination. When the subjects of the two clauses are the same, the two clauses means sequential process. So, in this case, the connective ‘-고’ means ‘ doing A first, and then doing B later’. But when the subjects of the two clauses are different, these two clauses express comparison, and are used with the topic marker ‘-은/는’.
