The present perfect connects an earlier event or situation to the present. It can report experience, a current result or a situation continuing up to now. It is not simply another name for any past event that matters.
Check the auxiliary and participle before interpreting the time phrase. These exercises distinguish completed past dates from continuing periods and avoid claiming that words such as already or just always require one tense in every variety of English.
These original exercises were prepared by English AIdol with AI assistance. A separate AI content review checked every question, answer explanation and teaching section. No human expert or examiner review, ETS endorsement, or calibrated difficulty is claimed. This page does not save answers or estimate an official score.
The subject determines have or has. Questions invert that auxiliary, and not follows it in negatives. The main verb remains a participle, including irregular forms such as written and taken.
The team members have written the summary.
Has the director taken a copy?
The supplier has not replied.
Interpret the time period
A completed event located at a finished past time normally uses the simple past. Present-perfect uses include experiences up to now and states continuing from an earlier starting point. Present relevance alone does not make every simple-past sentence wrong.
We signed the lease last Tuesday.
We have used this office since May.
Have you ever supervised an installation?
Separate starting point and duration
Since introduces a starting point; for introduces a duration. The present perfect can include either, and present-perfect continuous may also work with many ongoing activities. Do not force a simple/continuous distinction without a reason.
The museum has owned the archive for a decade.
The curator has known the donor since 2019.
Keep perfect and passive auxiliaries in order
A present-perfect passive uses have or has, then been, then the main past participle. The subject receives the action. Has been reviewing instead describes a person’s continuing activity.
The invoice has been approved.
The chairs have been delivered.
Worked example
The updated permit has ___ issued.
been
The permit receives the action. Has been issued is present-perfect passive: has + been + past participle. Being would not complete this structure.

Question 1
The new analyst ___ completed the supplier comparison.
(A) have
(B) having
(C) has
(D) does
Show answer and explanation for question 1
Answer: (C) has
Completed sentence: The new analyst has completed the supplier comparison.
(A) have: Have does not agree with the singular third-person subject.
(B) having: Having cannot supply the finite auxiliary in this sentence.
(C) has: Correct. The singular analyst takes has before the participle completed.
(D) does: Does requires a base verb, whereas completed is printed.

Transfer 1
Correct the tense without changing the date: “We have opened the branch in 2016.”
Check transfer 1
We opened the branch in 2016.
The sentence dates the completed opening event rather than describing a period up to now.
Transfer 2
Rewrite “Someone has repaired the projector” with the projector as subject.
Check transfer 2
The projector has been repaired.
The passive retains has and adds been before the main participle repaired.
Transfer 3
Compare “I have worked here for five years” with “I worked there for five years.”
Check transfer 3
The first connects the period to now; the second presents a completed past period.
Context can add detail, so do not use a duration alone as an automatic tense selector.
Sources checked on . The examples, questions and explanations are original teaching material, not official or recalled test items. This correction replaces the earlier lesson’s inappropriate IELTS-style scoring. An answer count on these exercises does not convert to an official TOEIC score.
No. Usage varies with context and variety of English. These questions test the printed structure or an explicit time relationship rather than rejecting every simple-past use with already.
Can simple and continuous perfect forms both be correct?
Yes, especially with activities continuing up to now. The simple may emphasise a result or amount; the continuous may emphasise the activity. Do not invent a distinction that the context does not support.
Why is has been sent different from has sent?
Has been sent is passive: the subject receives the sending action. Has sent is active: the subject does the sending and may take an object.
Can these questions predict my TOEIC score?
No. These original, untimed teaching questions have not been equated to an ETS form. Use them to explain and practise a language pattern, not to calculate an official score.
