請問此句省略的部分....

Question

Having graduated, he became a worker. 畢業後他當了工人
我猜原句是
After he have graduated,he became a worker.
不知是否正確呢?

Answer 1

Having graduated, he became a worker. (畢業後他當了工人)的原句是
“After he had graduated, he became a worker.”

我再進一步講，(畢業後他當了工人)也可以講
“After he graduated, he became a worker.” (原因：因為用了after或before表示時間先後的字，雖然是先畢業再變成工人，但在這裡不一定要用過去完成式來強調更早的動作。)

或 “After his graduation, he became a worker.”也可以。

Answer 2

用Before應該也說得通，而且這樣一來，用完成式會變得更說得過去。在畢業之前，他就當了工人。

Answer 3

After he [had] graduated, he became a worker.

Answer 4

Yea I think you are right ^_^
