This handout explains and describes the sequence of verb tenses in English.

Sequence of Tenses

Only two tenses are conveyed through the verb alone: present (“sing") and past (“sang"). Most English tenses, as many as thirty of them, are marked by other words called auxiliaries. Understanding the six basic tenses allows writers to re-create much of the reality of time in their writing.

Simple Present: They walk.

Present Perfect: They have walked.

Simple Past: They walked.

Past Perfect: They had walked.

Future: They will walk.

Future Perfect: They will have walked.

Usually, the perfect tenses are the hardest to remember. Here’s a useful tip: all of the perfect tenses are formed by adding an auxiliary or auxiliaries to the past participle, the third principal part.

1st principal part (simple present): ring, walk

2nd principal part (simple past): rang, walked

3rd principal part (past participle): rung, walked

In the above examples, will or will have are the auxiliaries. The following are the most common auxiliaries: be, being, been, can, do, may, must, might, could, should, ought, shall, will, would, has, have, had. 

Present Perfect

The present perfect consists of a past participle (the third principal part) with "has" or "have." It designates action which began in the past but which continues into the present or the effect of which still continues.

1. Simple Past: “Betty taught for ten years.” This means that Betty taught in the past; she is no longer teaching.

2. Present Perfect: “Betty has taught for ten years.” This means that Betty taught for ten years, and she still teaches today.

1. Simple Past: “John did his homework so he can go to the movies.” In this example, John has already completed his homework.

2. Present Perfect: “If John has done his homework, he can go to the movies.” In this case, John has not yet completed his homework, but he will most likely do so soon.

Present Perfect Infinitives

Infinitives also have perfect tense forms. These occur when the infinitive is combined with the word “have.” Sometimes, problems arise when infinitives are used with verbs of the future, such as “hope,” “plan,” “expect,” “intend,” or “want.”

I wanted to go to the movies.

Janet meant to see the doctor. 

In both of these cases, the action happened in the past. Thus, these would both be simple past verb forms.

Present perfect infinitives, such as the examples below, set up a sequence of events. Usually the action that is represented by the present perfect tense was completed before the action of the main verb.

1. I am happy to have participated in this campaign! The current state of happiness is in the present: “I am happy.” Yet, this happiness comes from having participated in this campaign that most likely happened in the near past. Therefore, the person is saying that he or she is currently happy due to an event that happened in the near past.

2. John had hoped to have won the trophy. The past perfect verbal phrase, “had hoped,” indicates that John hoped in the past, and no longer does. “To have won the trophy” indicates a moment in the near past when the trophy was still able to be won. Thus, John, at the time of possibly winning the trophy, had hoped to do so, but never did.

Thus the action of the main verb points back in time; the action of the perfect infinitive has been completed.

Past Perfect

The past perfect tense designates action in the past just as simple past does, but the past perfect’s action has been completed before another action.

1. Simple Past: “John raised vegetables.” Here, John raised vegetables at an indeterminate time in the past.

2. Past Perfect: “John sold the vegetables that he had raised.” In this sentence, John raised the vegetables before he sold them.

1. Simple Past: “Renee washed the car when George arrived.” In this sentence, Renee waited to wash the car until after George arrived.

2. Past Perfect: “Renee had washed the car when George arrived.” Here, Renee had already finished washing the car by the time George arrived.

In sentences expressing condition and result, the past perfect tense is used in the part that states the condition.

1. Ifhad done my exercises, I would have passed the test.

2. I think Sven would have been elected if he hadn't sounded so pompous.

Further, in both cases, the word if starts the conditional part of the sentence. Usually, results are marked by an implied then. For example:

If I had done my exercises, then I would have passed the test.

If Sven hadn’t sounded so pompous, then he would have been elected.

Again, the word then is not required, but it is implied.

Future Perfect

The future present tense is used for an action that will be completed at a specific time in the future.

1. Simple Future: “On Saturday, I will finish my housework.” In this sentence, the person will finish his or her housework sometime on Saturday.

2. Future Perfect: “By noon on Saturday, I will have finished my housework.” By noon on Saturday, this person will have the homework already done even though right now it is in the future.

1. Simple Future: “You will work fifty hours.” In this example, you will work fifty hours in the future. The implication here is that you will not work more than fifty hours.

2. Future Perfect: “You will have worked fifty hours by the end of this pay period.” By the end of this pay period, you would have already worked fifty hours. However, as of right now, this situation is in the future. The implication here is that you could work more hours.

Review

1. Judy saved thirty dollars. (past—the saving is completed)

2. Judy will save thirty dollars. (future—the saving has not happened yet)

3. Judy has saved thirty dollars. (present perfect—the saving has happened recently)

4. Judy had saved thirty dollars by the end of last month. (past perfect—the saving occurred in the recent past)

5. Judy will have saved thirty dollars by the end of this month. (future perfect—the saving will occur in the near future, by the end of this month)

This handout explains and describes the sequence of verb tenses in English.

Passive Verb Tenses

Often, writing teachers encourage the use of action verbs and the active tense. However, there are times when it makes more sense to use passive verbs instead.

Use passive verb tenses when you do not want to specify the actor.  If the actor is either unknown or irrelevant, you may not want to specify an actor: “Crimes were committed.” In this case, the actor’s name is purposely avoided.

Additionally, use passive verb tenses when you wish to foreground a topic that is not the action or actor. “Penicillin was developed in 1928.” In this case, penicillin is foregrounded instead of the developer and instead of the verb, developed.

 

Simple Present
Active: Passive
  • The company ships the computers to many foreign countries.
  • Computers are shipped to many foreign countries

In the active example of simple present, the company ships the computers. Here, the company is doing the action.

In the passive example of simple present, computers are foregrounded instead of the company. In this case, it doesn’t matter who sent the computers. 

 

Present Progressive (verbs ending in -ing)
Active: Passive:
  • A combination of wind, pressure, and moisture is forming the thunderstorm.
  • A thunderstorm is being formed.

In the active example of present progressive, the factors of the storm are emphasized rather than the storm itself.

In the passive example of present progressive, the storm is focused on rather than the factors of the storm.

Use the passive tense if you do not wish to detail the factors of the storm and instead wish to present the storm as the focus of the sentence.

 

Simple Past
Active: Passive:
  • The postal carrier delivered the package yesterday.
  • The package was delivered yesterday.

 

Past Progressive (verbs ending in -ing)
Active: Passive:
  • The producer was making an announcement.
  • An announcement was being made.

 

Future
Active: Passive:
  • Our representative will pick up the computer.
  • The computer will be picked up.

In the active example of the future tense, the representative is specified as the person who will pick up the computer. In this case, the owners of the computer know to look out for a specific person who represents this company.

In the active example of the future tense, we do not know who will pick up the computer, just that it will be picked up.

Use this tense if you do not want to specify who will pick up the computer.

 

Present Perfect
Active: Passive:
  • Someone has made the arrangements for us.
  • The arrangements have been made for us.

 

Past Perfect
Active: Passive:
  • They had given us visas for three months.
  • Visas had been given to us for three months.

 

Future Perfect
Active: Passive:
  • By next month we will have finished this job.
  • By next month this job will have been finished.

 

Modals (can, could, be able to, may, might, must, will, would)
Active: Passive:
  • You can use the computer.
  • The computer can be used.

In the active tense example of the modal verb, the second person pronoun, you, is directly addressed as the person who can use the computer.

In the passive tense example of the modal verb, no single person is addressed. Therefore, the computer can be used by anyone.

Verb Tense Consistency

Throughout this document, example sentences with nonstandard or inconsistent usage have verbs in red.

Controlling shifts in verb tense

Writing often involves telling stories. Sometimes we narrate a story as our main purpose in writing; sometimes we include brief anecdotes or hypothetical scenarios as illustrations or reference points in an essay.

Even an essay that does not explicitly tell a story involves implied time frames for the actions discussed and states described. Changes in verb tense help readers understand the temporal relationships among various narrated events. But unnecessary or inconsistent shifts in tense can cause confusion.

Generally, writers maintain one tense for the main discourse and indicate changes in time frame by changing tense relative to that primary tense, which is usually either simple past or simple present. Even apparently non-narrative writing should employ verb tenses consistently and clearly.

General guideline: Do not shift from one tense to another if the time frame for each action or state is the same.

Examples:

1. The instructor explains the diagram to students who asked questions during the lecture.

Explains is present tense, referring to a current state; asked is past, but should be present (ask) because the students are currently continuing to ask questions during the lecture period.

CORRECTED: The instructor explains the diagram to students who ask questions during the lecture.

2. About noon the sky darkened, a breeze sprang up, and a low rumble announces the approaching storm.

Darkened and sprang up are past tense verbs; announces is present but should be past (announced) to maintain consistency within the time frame.

CORRECTED: About noon the sky darkened, a breeze sprang up, and a low rumble announced the approaching storm.

3. Yesterday we walk to school but later rode the bus home.

Walk is present tense but should be past to maintain consistency within the time frame (yesterday); rode is past, referring to an action completed before the current time frame.

CORRECTED: Yesterday we walked to school but later rode the bus home.

General guideline: Do shift tense to indicate a change in time frame from one action or state to another.

Examples:

1. The children love their new tree house, which they built themselves.

Love is present tense, referring to a current state (they still love it now;) built is past, referring to an action completed before the current time frame (they are not still building it.)

2. Before they even began deliberations, many jury members had reached a verdict.

Began is past tense, referring to an action completed before the current time frame; had reached is past perfect, referring to action from a time frame before that of another past event (the action of reaching was completed before the action of beginning.)

3. Workers are installing extra loudspeakers because the music in tonight's concert will need amplification.

Are installing is present progressive, referring to an ongoing action in the current time frame (the workers are still installing, and have not finished;) will need is future, referring to action expected to begin after the current time frame (the concert will start in the future, and that's when it will need amplification.)

Controlling shifts in a paragraph or essay

General guideline: Establish a primary tense for the main discourse, and use occasional shifts to other tenses to indicate changes in time frame.

Hints:

Using other tenses in conjunction with simple tenses

It is not always easy (or especially helpful) to try to distinguish perfect and/or progressive tenses from simple ones in isolation, for example, the difference between simple past progressive ("She was eating an apple") and present perfect progressive ("She has been eating an apple"). Distinguishing these sentences in isolation is possible, but the differences between them make clear sense only in the context of other sentences since the time-distinctions suggested by different tenses are relative to the time frame implied by the verb tenses in surrounding sentences or clauses.

Example 1: Simple past narration with perfect and progressive elements

On the day in question...

By the time Tom noticed the doorbell, it had already rung three times. As usual, he had been listening to loud music on his stereo. He turned the stereo down and stood up to answer the door. An old man was standing on the steps. The man began to speak slowly, asking for directions.

In this example, the progressive verbs had been listening and was standing suggest action underway at the time some other action took place. The stereo-listening was underway when the doorbell rang. The standing on the steps was underway when the door was opened. The past perfect progressive verb had been listening suggests action that began in the time frame prior to the main narrative time frame and that was still underway as another action began.

If the primary narration is in the present tense, then the present progressive or present perfect progressive is used to indicate action that is or has been underway as some other action begins. This narrative style might be used to describe a scene from a novel, movie, or play, since action in fictional narratives is conventionally treated as always present. For example, we refer to the scene in Hamlet in which the prince first speaks (present) to the ghost of his dead father or the final scene in Spike Lee's Do the Right Thing, which takes place (present) the day after Mookie has smashed (present perfect) the pizzeria window. If the example narrative above were a scene in a play, movie, or novel, it might appear as follows.

Example 2: Simple present narration with perfect and progressive elements

In this scene...

By the time Tom notices the doorbell, it has already rung three times. As usual, he has been listening to loud music on his stereo. He turns the stereo down and stands up to answer the door. An old man is standing on the steps. The man begins to speak slowly, asking for directions.

In this example as in the first one, the progressive verbs has been listening and is standing indicate action underway as some other action takes place. The present perfect progressive verb has been listening suggests action that began in the time frame prior to the main narrative time frame and that is still underway as another action begins. The remaining tense relationships parallel those in the first example.

In all of these cases, the progressive or -ing part of the verb merely indicates ongoing action, that is, action underway as another action occurs. The general comments about tense relationships apply to simple and perfect tenses, regardless of whether there is a progressive element involved.

It is possible to imagine a narrative based on a future time frame as well, for example, the predictions of a psychic or futurist. If the example narrative above were spoken by a psychic, it might appear as follows.

Example 3: Simple future narration with perfect and progressive elements

Sometime in the future...

By the time Tom notices the doorbell, it will have already rung three times. As usual, he will have been listening to loud music on his stereo. He will turn the stereo down and will stand up to answer the door. An old man will be standing on the steps. The man will begin to speak slowly, asking for directions.

In this example as in the first two, the progressive verbs will have been listening and will be standing indicate ongoing action. The future perfect progressive verb will have been listening suggests action that will begin in the time frame prior to the main narrative time frame and that will still be underway when another action begins. The verb notices here is in present-tense form, but the rest of the sentence and the full context of the narrative cue us to understand that it refers to future time. The remaining tense relationships parallel those in the first two examples.

General guidelines for use of perfect tenses

In general the use of perfect tenses is determined by their relationship to the tense of the primary narration. If the primary narration is in simple past, then action initiated before the time frame of the primary narration is described in past perfect. If the primary narration is in simple present, then action initiated before the time frame of the primary narration is described in present perfect. If the primary narration is in simple future, then action initiated before the time frame of the primary narration is described in future perfect.

Past primary narration corresponds to Past Perfect (had + past participle) for earlier time frames

Present primary narration corresponds to Present Perfect (has or have + past participle) for earlier time frames

Future primary narration corresponds to Future Perfect (will have + past participle) for earlier time frames

The present perfect is also used to narrate action that began in real life in the past but is not completed, that is, may continue or may be repeated in the present or future. For example: "I have run in four marathons" (implication: "so far... I may run in others"). This usage is distinct from the simple past, which is used for action that was completed in the past without possible continuation or repetition in the present or future. For example: "Before injuring my leg, I ran in four marathons" (implication: "My injury prevents me from running in any more marathons").

Time-orienting words and phrases like before, after, by the time, and others—when used to relate two or more actions in time—can be good indicators of the need for a perfect-tense verb in a sentence.

Sample paragraphs

The main tense in this first sample is past. Tense shifts are inappropriate and are indicated in bold.

 

The gravel crunched and spattered beneath the wheels of the bus as it swung into the station. Outside the window, shadowy figures peered at the bus through the darkness. Somewhere in the crowd, two, maybe three, people were waiting for me: a woman, her son, and possibly her husband. I could not prevent my imagination from churning out a picture of them, the town, and the place I will soon call home. Hesitating a moment, I rise from my seat, these images flashing through my mind.

  (adapted from a narrative)

Inappropriate shifts from past to present, such as those that appear in the above paragraph, are sometimes hard to resist. The writer becomes drawn into the narrative and begins to relive the event as an ongoing experience. The inconsistency should be avoided, however. In the sample, will should be would, and rise should be rose.

The main tense in this second sample is present. Tense shifts—all appropriate—are indicated in bold.

 

A dragonfly rests on a branch overhanging a small stream this July morning. It is newly emerged from brown nymphal skin. As a nymph, it crept over the rocks of the stream bottom, feeding first on protozoa and mites, then, as it grew larger, on the young of other aquatic insects. Now an adult, it will feed on flying insects and eventually will mate. The mature dragonfly is completely transformed from the drab creature that once blended with underwater sticks and leaves. Its head, thorax, and abdomen glitter; its wings are iridescent in the sunlight.

  (adapted from an article in the magazine Wilderness)

 

This writer uses the present tense to describe the appearance of a dragonfly on a particular July morning. However, both past and future tenses are called for when she refers to its previous actions and to its predictable activity in the future.
