我完成了任务英文

I've accomplished what need to be done by myself

I have finished my tasks that I should to do

I have finished the work that I should do myself.

mission accomplished希望对你有所帮助！这里的accomplished为过去分词做定语修饰mission

1、此意包括两层意思，可以拆分开分别根据需要进行不同的翻译

I have done my assignment.（做完分配任务）

I have fulfilledthe role.（履行完角色）

I have completedmy task （完成指定任务）

I have finishedmy errand （结束差事）

I have accomplishedmy mission （完成使命）

I should do the assignment

I have to playthe role.

I ought to dothe task

I am supposed todo the errand

I am necessary toaccomplish the mission

2、把上面的两个意思合在一起（后面的要省略重复部分，改为定语从句）

I have done my assignment (that) I should do.

I have fulfilled the role (that) I have to play.

I have completed my task (that) I ought to do.（完成指定任务）

I have finished my errand (that) I am supposed to do（结束差事）

I have accomplished my mission (that) I am necessary to do.

3、还可以把 “先行词 + 定语从句” 改为 what 从句

I have done what I should do.

I have fulfilled what I have to play.

I have completed what I ought to do.（完成指定任务）

I have finished what I am supposed to do（结束差事）

I have accomplished what I am necessary to do.
