Overview
How This Grammar Works
status update for your life and experiences. If you want to say you did something at an unspecified time in the past, or that an action has a direct result in the present, the Present Perfect is your go-to.I have visited London three timesfocuses on the experience, not a specific date. This contrasts sharply with the Simple Past, which tells us precisely when it happened (e.g.,
I visited London *last year*). When using the Present Perfect for actions with present results, the connection is even clearer.
Have you slept well?– you're asking about a past action (sleeping) that directly explains their *current* state.
Common Mistakes

- 1✗ Wrong: He didn't finish his homework yet.
Yet (and already) signal that the action is expected to happen, or is still incomplete, making the Present Perfect the correct choice for connecting past to now.- 1✗ Wrong: Where is John? I saw him five minutes ago.

Quick FAQ
What's the main difference between I went and I have gone?
I went uses the Simple Past, meaning you went somewhere at a specific past time, and you are no longer there (e.g.,
I went to the store yesterday).
I have gone uses the Present Perfect, meaning you are currently *not here* because you went somewhere (e.g., "John isn't home; he has gone to the library").
Can I use ever and never with the Present Perfect?
Absolutely! Ever is used in questions about past experiences (e.g.,
Have you ever seen a whale?).
Never is used in negative statements about experiences (e.g., I have never traveled abroad.). These are classic examples of the Present Perfect expressing experience.
Why is Mastering Irregular Verbs so important for this chapter?
The Present Perfect requires the past participle form of the verb. While regular verbs simply add '-ed', irregular verbs have unique forms (e.g., *do-done, write-written, speak-spoken*). Without knowing these, you can't correctly form the Present Perfect, which is crucial for connecting past to now.

よくある間違い
You cannot use 'yesterday' with the Present Perfect. If the time is specific, use the Simple Past.
Remember to use 'has' for he, she, and it.
Do not use the Simple Past form (saw) with 'have'. You must use the Past Participle (seen).

have finished my homework」は、「宿題は『今』終わったよ」っていう意味になるんだね。have または has と、動詞の「過去分詞形」(V3)を組み合わせて作るよ。例えば、「I have eaten」とか「She has seen」のように、いつも2つの単語で一まとまりの動詞句になるんだ。
