Step 2. The present perfect tense

1. We use the present perfect tense to talk about actions that started in the past and continue to the present.

e.g. I have lived here since I was born.

She has worked in this factory for nine years.

2. We use the present perfect tense to talk about an action that happened in the past and have a connection with the present.

e.g. Eddie has just eaten Hobo’s food.

（Eddie ate the food, and now Hobo has nothing to eat.)

I have already seen the film?

(I saw the film in the past and now I still remember something about the film.)

3. We also use the present perfect tense to talk about how many times an action has happened till now.

e.g. I have already read this book many times.

Mr Chen has been to the USA twice.

4. We make positive statements in the present perfect tense like this:

I / You/ We / They have ?arrived.He / She / It has5. We make negative statements in the present perfect tense like this:

I / You/ We / They have ?not??arrived.He / She / It has6. We ask and answer questions using the present perfect tense like this:

HaveI / you/ we / theyarrived?Hashe / she / it Yes,I / you/ we / theyhe / she / it No,I / you/ we / theyhe / she / it 7. We form the past participles of some regular verbs by adding –ed, just as what we do to form the simple past tense of these verbs:

Most verbs +edfinish → finishedVerbs ending in -e +d?change → changedVerbs ending in a consonant +y -y +iedcarry → carriedShort verbs ending in a vowel + a consonant double?the consonant +edstop → stopped8. We form the past participle of irregular verbs differently. Here are some examples:

No changecome→come hurt → hurtChange the vowelhold → held win → wonChange the consonantlend→lent build → builtChange the vowel(s) and the consonant(s)catch →caught keep→ kept forget→ forgotten?
