Two Tense Errors, One Wrong Rule
Rina is writing a self-introduction for her English class. Her draft has three blanks.
'Hello. I'm Rina. I ( 1 ) in Hamamatsu for ten years. Last summer I ( 2 ) to Australia with my family. I ( 3 ) many countries, but Australia was the best.'
Choices - (1): live / lived / have lived / am living. (2): go / went / have gone / was going. (3): visit / visited / have visited / am visiting.
Rina answers: (1) lived, (2) went, (3) visited. Her explanation: 'For (1), ten years is a long time and it is finished, so past tense. For (2), last summer is past. For (3), the sentence before is about the past, so I kept it past.' In Japanese she would write「10年間浜松に住んでいます」, and she says the English present perfect 'sounds like 住んでいました', which she is sure is wrong. The teacher marks (2) correct and (1) and (3) wrong.
1. Correct blank (1), state the rule in one sentence Rina can reuse, and explain why her Japanese sentence is not a reliable guide here.

Answer: have lived.
I have lived in Hamamatsu for ten years.
The rule in one sentence. Use the present perfect with for + a length of time when the situation began in the past and is still true now; use the past simple only when the period is closed (e.g. I lived in Osaka for ten years, but we moved here in 2015).
Why 'ten years is a long time and it is finished' fails. Both halves of Rina's reasoning are invented. Nothing in the passage says she has left Hamamatsu - she is introducing herself at her own school, in the present. Length is irrelevant: for ten minutes and for ten years behave identically. What decides the tense is whether the period is open or closed at the moment of speaking, not how long it is.
Why the Japanese sentence misleads her. 「住んでいます」 is present progressive in form but covers exactly the range that English splits between live and have lived. So the natural Japanese sentence points at the English present, while the correct English form is the present perfect. Rina has felt this mismatch, but she has drawn the wrong conclusion from it: she decided the present perfect must be the past (「住んでいました」). The mapping is not one-to-one, so Japanese cannot be used to check English tense - only to generate the idea.
The test she can apply. Say the sentence with and I still do added: I have lived in Hamamatsu for ten years, and I still do - natural. I lived in Hamamatsu for ten years, and I still do - contradictory. That single addition settles it.
2. Correct blank (3). Explain the difference between 'Last summer I went to Australia' and 'I have visited many countries', and say why 'visited' is the most tempting wrong choice.

Answer: have visited.
I have visited many countries, but Australia was the best.
The two sentences are not the same kind of statement.
- Last summer I went to Australia - a single finished trip at a stated past time. The time expression last summer closes the event, so past simple is required.
- I have visited many countries - experience up to now, with no time given. The speaker is not reporting a trip; she is reporting the shape of her life so far. Present perfect is required.
Why the following clause does not force the past. Australia was the best is a comment on one member of the set, and it is fine in the past after a present perfect: the set is open (have visited), the ranking is about a finished trip (was). Students expect a passage to keep one tense throughout; real English changes tense when the viewpoint changes from 'my life so far' to 'that one summer'.
Why 'visited' is so tempting.
- The previous sentence is past (went), and Rina carried the tense forward - a habit, not a reason.
- Visited looks like the natural partner of a list of places, which feels like finished history.
- Nothing in the clause marks it as wrong: no time word is present, so the error is invisible unless the student asks 'is there a stated time?' That is precisely the question the item is testing.
Practical check. If there is no past time expression and the meaning is 'how many / how often / ever / never / before', use the present perfect. If there is a past time expression (last summer, in 2019, yesterday), use the past simple. Rina's mistake was applying rule two where rule one belonged.
3. Rina asks for one decision procedure that would have caught both errors. Give her a three-question test, and apply it to blanks (1) and (3) to show it works.

The three questions, asked in this order.
- Is there a finished past time expression in this clause? (last summer, yesterday, in 2015, when I was a child) → past simple. If no, go to 2.
- Does the situation still continue, or is it experience up to now? (for ten years and still there; ever; never; many times; so far) → present perfect. If no, go to 3.
- Is it a fact about the past with no present connection? → past simple.
Applying it to blank (1): I ___ in Hamamatsu for ten years.
- Q1: no past time expression (for ten years is a length, not a finished point). → go on.
- Q2: does she still live there? She is introducing herself at her school now; nothing says she moved. Yes → have lived.
Applying it to blank (3): I ___ many countries.
- Q1: no past time expression. → go on.
- Q2: many countries is a count of experience up to now, not a single finished event → have visited.
Applying it to blank (2) as a control: Last summer I ___ to Australia. Q1 says yes (last summer) → went, present perfect blocked. This is the case Rina already gets right, so it shows the procedure is consistent with her own intuition.
Why the order matters. Students who start from 'what tense is the sentence before?' or 'how long is the period?' will keep making these two errors. Starting from the presence or absence of a finished time expression gives the same answer for (2) that she already reached, and reverses (1) and (3) - which is exactly the correction needed.
