PRESENT PERFECT

Present Perfect We use the Present Perfect for actions in

the past which have a connection to the present. The time when these actions happened is not important.

We use the Present Perfect for recently completed actions.

We use the Present Perfect for actions beginning in the past and still continuing.

Present Perfect - Use

It is a combination of past and present. An actions in the past has something to do with the present.

1) Result of an action in the past is important in the present (It is not important when this action happened. When we use a specific time in the past - e.g. yesterday - then we use the Simple Past.)

Has Peggy ever been to Tokyo? (Has Peggy been there or not?)

2) Recently completed actionsHe has just played handball. (It is over

now.)

Actions beginning in the past and still continuing - mostly with since (point of time) or for (period of time)

4) together with lately, recently, yet

PRESENT PERFECT FORM

The present perfect of any verb is composed of two elements :

the appropriate form of the auxiliary verb to have (present tense), plus the past participle of the main verb.

The past participle of a regular verb is base+ed,

e.g. played, arrived, looked. For irregular verbs, see the Table of irregular verbs .

Affirmative Subject to have past participle

She has visited

Subject to have + not past participle

She hasn't visited

Interrogative to have subject past participle

Has she visited..?

Interrogative negative

to have + not subject past participle Hasn't she visited...?

Example: to walk, present perfectAffirmative I have walked You have walked He, she, it has walked We have walked You have walked They have walked

Present Perfect - Spelling

Add -ed with regular verbs.regular verbsinfinitive + -ed

Sometimes the are exceptions in spelling when adding -ed.

1) consonant after a short, stressed vowel at the end of the word

stop – stopped swap – swapped

We do not double the consonant if it is not stressed:benefit - benefited (Here we stress the first 'e', not the 'i'.)

In Britsh English we double one -l at the end of the word:travel - travelled

2) one -e at the end of the word

Leave out the -e. Add -d.

love – loved

save – saved

3) verbs ending in –yVerbs ending in 'y' preceded by a vowel (a,

e, i, o, u):Add -ed.

play - played

Change 'y' to 'i' after a consonant. Then add -ed.
