Ask yourself one question before you open your mouth: am I telling them what I have been busy with, or what I have got done? The process takes have been doing. The result takes have done. Almost everything else follows from that.
The two of them live happily in one breath:
I’ve been interviewing candidates all week, and I’ve learned a lot about people.
The process on the left, what it added up to on the right. Keep that sentence in your pocket — when a tense choice stalls you mid-conversation, say it in your head and copy the half that matches what you mean.
have been + V-ing): for, since, lately, recently, all day, all week.have + V3): already, just, yet, ever, and anything you can count — five books, fourteen novels, thirty marathons.A number is the loudest clue in the room. I’ve been writing a new novel for a few months is a process; I’ve written fourteen novels is a scoreboard.
Many verbs take both forms, and the meaning shifts. I’ve been learning English for years keeps the process running. I’ve learned a lot puts the result on the table. Neither is more correct — pick the one that matches what you want to stress.
State verbs stay out of continuous. Know, seem, belong, look like: these describe a condition rather than an activity, so they resist -ing altogether.
A finished episode belongs to Past Simple. Telling the story of yesterday’s interview? The backbone is Past Simple all the way through. Present Perfect only steps in where the past reaches into now: I’ve just finished an interview that has made me feel disappointed. That just is doing real work — it says the thing still hangs over you.
Straight from my homework. The third column is the part worth remembering.
| What I wrote | What it should be | Why |
|---|---|---|
| Instead I was reading a lot | Instead I've been reading a lot | The reading started earlier in the week and is still going on. That link to now needs a present tense, not Past Continuous. |
| since begin of summer | since the beginning of summer | "Since" wants a noun, and this one takes an article: the beginning, the end, the start. |
| faster in reading | faster at reading | Good, better and faster all take "at" before an activity: good at small talk, faster at reading. |
| spontaneous small talks | spontaneous small talk | "Small talk" is uncountable. No plural -s, and no "a" in front of it. |
| The candidate has been looking like a geek | The candidate looked like a geek | "Look like" is a state verb, so it avoids continuous forms — and yesterday's interview is a closed episode, which puts it in Past Simple. |
| Last time I've been preparing for a marathon | Lately I've been preparing for a marathon | "Last time" means "on the previous occasion". For "in recent weeks" the words are "lately" and "recently". |
| The last week I've met a friend | Last week I met a friend | "Last week" is a finished point in the past, so Present Perfect is out and Past Simple is in — and it takes no article. |
