"discharge", as a verb, has several meanings.
1. 意思是 "履行"
- transitive
- somebody/something "discharge" something (~duties/responsibilities/obligations)
- to perform a task, especially an official one [from Cambridge dictionary]
2. 意思是 "解除" (允許…出院; 允許…退伍; 解僱)
- transitive; usually in passive voice
- somebody/something "discharge" somebody (from something) (~hospital/prison/court/*job related terms*)
- to give somebody official permission to leave a place or job; [from Oxford dictionary]
The MAIN difference between 1 & 2 is :
the word "responsibilities", among other abstract nouns such as duty and obligation, is the direct object of the verb "discharge" in sentence 1, whereas, "responsibility", among other job-related terms, is the object of the preposition "from" immediately following the passive of "discharge" in sentence 2.
