Present Perfect

We use the present perfect (have + past participle) for:

• an action that happened at an unstated time in the past. The emphasis is on the action, the time when it occurred is unimportant or unknown. I have washed the car. Ann has been to London once.

• an action which started in the past and continues up to the present, especially with stative verbs (see above) such as be, have, like, know etc. I have known the Browns for six years.

• a recently completed action. I have painted the house.

• personal experiences or changes. She has put on five kilos.

The time expressions we use with the present perfect are: for, since, already, always, just, ever, never, so far, today, this week/month etc, how long, lately, recently, still (in negations), yet, by now etc

Present Perfect Continuous

We use the present perfect continuous (have + been + verb -ing):

• to put emphasis on the duration of an action which started in the past and continues up to the present. We have been decorating the living room all morning.

• for an action which started in the past and lasted for some time. It may still be continuing or has finished already with the result visible in the present. He's soaking wet because it has been raining all morning.

• to express anger, irritation or annoyance. He has been taking my things without my permission.

• for repeated actions in the past continuing to the present. She has lost weight because she has been dieting.

The time expressions we use with the present perfect continuous are: for, since, how long, all day/morning/month etc, lately, recently

Note: with the verbs live, work, teach and feel we can use the present perfect simple or the present perfect continuous with no difference in meaning. She has worked/has been working as a teacher for the last eight years.
