A perfect tense sentence:
I have made dinner.
Although this gives information about a prior action (my making the dinner), the focus is likely to be on the present consequences of that action, which is the fact that the dinner is now ready.

What is a past participle:
Example: "stolen" is the past participle of "steal";
"spoken" is the past participle of "speak";
"seen" is the past participle of "see";
"taken" is the past participle of "take".
In Chinese, the perfect tense construction is:
