Differences between Present Perfect and Present Perfect Continuous

[Alice Chu]

Dear teachers,
Could you please tell me if my understanding is correct and help me teach my students correctly?

Present perfect tense is not used with specific past time.
(1)a finished action before now
(2)a finished action with a present result
(3)a finished action indicating how many or how much
(4)a finished action used with an unfinished time word(this week…)
(5)a finished action indicating life experience before now
(6)an unfinished action indicating how long, used with for or since

Present perfect continuous tense is not used with stative verbs or specific past time.
(1)a finished action with a present result we can see, feel or smell
(2)an unfinished action indicating how long, used with for or since
(3)an unfinished action indicating temporary situations

Could you please check and correct the following examples and meanings?
1. She has cleaned her house. It looks good now.
→The action was completed in the recent past and has a result in the present.

2. She has been cleaning her house, so she is tired now.
→The action has stopped recently and has a present result we can see. The work could be completed or not.

3. She has been cleaning her house, and she is not finished yet.
→The action started in the past and continues to the present. The action is not completed.

4. (A)She has cleaned her house for two hours. She’ll be finished soon.
(B)She has been cleaning her house for two hours. She’ll be finished soon.
→The action started two hours ago and continues to the present. I think the two sentences have the same meaning. If I am wrong, could you please tell me why?

5. (A)I have worked in London for 20 years. I like my job.
→The action started 20 years ago and continues to the present. The timeline continues to the present.
(B)I have been working in London for 20 years. I like my job.
→The action started 20 years ago and continues to the present. It will continue to the future. The timeline continues to the future.

6. I usually work in London, but I have been working in Paris for a month / for the last month.
→The temporary action started a month ago and continues to the present.

7. (A)I have lived in London since I was born.
(B)I have been living in London since I was born.
→The permanent action started in the past and continues to the present.
I think the two sentences have the same meaning. If I am wrong, could you please tell me why?

8. (A)She has written two novels this year.
→a completed action used with unfinished time
(B)She wrote two novels last year.
→a completed action used with finished time

9. I have been in Paris for two weeks. → correct
I have gone to Paris for two weeks. → incorrect

10. He has been to Paris several times. → correct
He has gone to Paris several times. → incorrect

If I miss any uses of the two tenses above, could you please give me examples and explanations? Thank you very much.

Hello, dear teachers.
Could you please tell me if my understanding is correct?

When present perfect tense indicates duration, it is normally used with non-continuous verbs. However, it can be used with the following continuous verbs: live, work, teach, study, learn. It can also be used with continuous verbs in negative sentences to indicate state duration.

1. I have studied / have been studying English since I was 7.
2. They have been married for 25 years. They are a happy couple.
3. I know you well because I have known you for over 20 years.
4. He hasn’t smoked for two weeks. He is trying to quit smoking.
5. I haven’t eaten steak for several weeks. I can’t wait to eat some now.

6. She has learnt / has been learning to drive for two months.
Could you please tell me which of the timelines below is correct, the green one or the red one? Thank you very much?

However, for actions or states that don't have this idea, the continuous form normally implies duration, and the non-continuous from completion. 4A is therefore not very likely.

Is this a typo?

I assume that you meant to say:

... the continuous form normally implies duration, and the non-continuous form, completion. 4A is therefore not very likely.
