INTRODUCTION

The present perfect [present perfect] is a tense used to express completed actions that occurred in the past, are connected to, and affect the present.

When expressed in its interrogative form, the verb is used to ask questions.

FORM

The present perfect, in its interrogative form, has this structure:

Have + subject + past participle + …?

Have/has: the third person singular changes from have to has;

Regular past participles are formed by adding -d or -ed to the base form of verbs.

You have to learn the irregular past participles by heart.


HAVE SUBJECT PAST PARTICIPLE QUESTION


EXAMPLE

  1. Situations of the past with results in the present

Have I lost my car keys?

Have you put on weight?

Have we finished our homework?

     2.Completed actions that refer to the experiences lived up to now

Have I talked to her four times?

Has she visited this castle?

Have they traveled without their computer?

WEAR

We use the present perfect, in its interrogative form, to ask about:

  1. Situations of the past with results in the present;
  2. Completed actions that refer to the experiences lived up to now.

SUMMARY

We use the present perfect, in its interrogative form, to ask about completed actions that occurred in the past, are connected to, and affect the present.

When we use the present perfect in the interrogative, we start with have followed by the subject and the past participle, the sentence ends with a question mark (Have + subject + past participle + …?). The third person singular uses has.


NOTE: Normally the past participle is used to form the perfect tenses and indicates completed or past actions. It is formed by adding -d or -ed to the base form of regular verbs, while irregular verbs have different forms that you need to memorize.


For example:

— “Has she worked on an important project this morning?” = We use the present perfect because the action in the past still affects the present.

♦ “Did she work on an important project yesterday?” = We use the simple past tense because the past action has ended and it is not necessary to emphasize its effects in the present.
