The Tense System

Lesson 2: The Simple Present Tense

Lesson: 2 of 14 | Level: 🟢 Elementary

1. Lesson Overview

The simple present tense is the most frequently used tense in English. It is the tense of facts, habits, routines, schedules, and permanent truths — the tense we reach for when we want to describe how the world is rather than how it was or how it will be. Despite its name, the simple present is not always used to describe things happening at the present moment — that function belongs to the present continuous. Understanding what the simple present actually does, and when it is and is not appropriate, is one of the most important steps in mastering the English tense system.

This lesson examines the simple present in full — its formation, its many uses from elementary to advanced, and the rules that govern its behaviour across a wide range of contexts.

Objectives

By the end of this lesson, you will be able to:

• Form the simple present tense correctly in affirmative, negative, and question forms
• Identify and apply at least fifteen distinct uses of the simple present tense
• Understand when the simple present is and is not appropriate
• Recognise and correct common errors in the use of the simple present tense

2. Core Content

A. Forming the Simple Present Tense

The simple present tense is formed using the base form of the verb for all persons except the third person singular, which adds -s or -es.

Affirmative form

Spelling rules for the third person singular

Most verbs add -s: flows, retreats, rises, contains. Verbs ending in -s, -ss, -sh, -ch, -x, or -o add -es: passes, washes, reaches, fixes, goes. Verbs ending in a consonant + y change y to i and add -es: studies, carries, identifies. Verbs ending in a vowel + y simply add -s: plays, conveys, displays.

Negative form

The negative is formed with do not (don’t) or does not (doesn’t) + base form.

Question form

Questions are formed with do or does + subject + base form.

For example:

The Amazon River carries approximately 20 per cent of all the fresh water that flows into the world’s oceans. Does the Amazon flood every year? Yes — it floods predictably during the wet season.

In the first sentence, carries is the third person singular form — the -s ending signals agreement with the Amazon River. In the second, does is the auxiliary verb used to form the question, and flood is the base form.

B. The Main Uses of the Simple Present Tense

1. Permanent facts and scientific truths

The simple present is used to express facts that are permanently or generally true — facts about the natural world, scientific laws, and established knowledge that hold regardless of time.

For example:

Water freezes at zero degrees Celsius and boils at one hundred degrees Celsius at sea level. The Earth orbits the Sun once every 365.25 days at a speed of approximately 107,000 kilometres per hour.

2. Habits and routines

The simple present expresses actions that happen regularly — habits, routines, and repeated events. It is frequently accompanied by adverbs of frequency such as always, usually, often, sometimes, rarely, and never.

For example:

Scientists at the research station record temperature data every hour throughout the year. The team regularly collects water samples from three different depths to monitor changes in ocean chemistry.

3. General states and conditions

The simple present is used with stative verbs to describe ongoing states — conditions that exist generally, without reference to a specific moment in time.

For example:

The Mariana Trench contains the deepest point on Earth, reaching a depth of approximately 11,034 metres. Hydrothermal vents support ecosystems that depend entirely on chemosynthesis rather than photosynthesis.

4. Scheduled future events

The simple present refers to future events that are part of a fixed schedule or timetable — events whose occurrence is certain and planned in advance.

For example:

The expedition departs from Cape Town on the fourteenth of March and returns in June. The international climate conference opens in Geneva next Monday and runs for five days.

5. Narrative and literary present

The simple present is used in fiction, storytelling, film synopses, and literary analysis to describe events in a narrative — creating a sense of immediacy and drawing the reader into the action.

For example:

In the opening chapter, Darwin boards the Beagle and sets sail from Plymouth on a voyage that will change the history of science. The submersible descends slowly into the darkness, its cameras scanning the ocean floor for signs of undiscovered life.

6. Academic and reporting present

The simple present is used in academic writing to report the findings, arguments, and claims of studies, texts, and researchers — even when the work was produced in the past. This is sometimes called the academic present or reporting present.

For example:

Darwin argues in On the Origin of Species that all species of life have evolved from common ancestors through the process of natural selection. The study finds a strong positive correlation between rising ocean temperatures and the increasing frequency of coral bleaching events.

7. Performative statements

The simple present is used in performative utterances — statements in which the act of speaking constitutes the performance of an action. These include declarations, promises, apologies, guarantees, and formal announcements.

For example:

The committee hereby declares the new research station officially open. I promise to submit the full written report before the end of the working week.

8. Instructions and procedural writing

The simple present is used in instructions, manuals, recipes, and procedural texts to describe steps that must be followed — presenting each step as a fact about what happens in the process.

For example:

The researcher calibrates the instrument before each use and records the baseline reading in the data log. The sample is placed in the centrifuge, which separates its components by density over a period of thirty minutes.

9. Commentaries and demonstrations

The simple present is used in sports commentary, live demonstrations, guided tours, and real-time narration to describe events as they happen — giving the description an immediate, present-tense quality even when it is written or scripted.

For example:

The research vessel approaches the site and the team prepares to deploy the submersible for its deepest dive yet. The presenter places the rock sample under the microscope and the audience observes the crystal structure clearly.

10. Zero conditional sentences

The simple present is used in both the if-clause and the main clause of zero conditional sentences — expressing general truths and cause-and-effect relationships that are always true.

For example:

If the temperature drops below zero, water freezes and expands, exerting enormous pressure on surrounding rock. When tectonic plates collide, the resulting pressure forces rock upward, forming mountain ranges over millions of years.

11. Time clauses referring to the future

The simple present is used in time clauses introduced by when, as soon as, before, after, until, once, and by the time — even when the main clause refers to the future. English does not use will in these subordinate time clauses.

For example:

As soon as the glacier reaches the coastline, it begins to calve icebergs that drift northward into shipping lanes. Once the data is collected and verified, the team will publish its findings in a peer-reviewed journal.

12. Headlines and captions

The simple present is used in newspaper headlines, photo captions, and broadcast news to report recent events — giving them a sense of immediacy and present relevance.

For example:

Scientist discovers new species in the deep ocean near the Mariana Trench. Glacier retreats by record amount in a single year, scientists warn.

13. Proverbs, aphorisms, and universal truths

The simple present is used in proverbs, maxims, and aphorisms — statements that express timeless truths about human experience or the natural world.

For example:

Nature abhors a vacuum — a principle first articulated by Aristotle and later refined and tested by Galileo. The simplest explanation that accounts for all the available evidence is generally the most likely to be correct.

14. Exclamative and emphatic constructions

The simple present is used in certain exclamative and emphatic constructions — particularly with here and there — to describe actions happening at the very moment of speaking.

For example:

Here comes the research vessel — right on schedule after three months at sea. There goes the last known specimen of the species, carried away by the current before it could be captured.

15. Introductory clauses in formal writing

The simple present is used in introductory and framing clauses in formal and academic writing — particularly to introduce the purpose, structure, or argument of a paper, report, or chapter.

For example:

This paper examines the long-term effects of rising ocean temperatures on coral reef biodiversity across the Indo-Pacific region. The following section presents the methodology used to collect and analyse the deep-sea sediment core samples.

16. Expressing future meaning in conditional clauses

The simple present is used in conditional clauses of the first type — where the condition is possible or likely — even though the meaning refers to future time.

For example:

If global temperatures rise by more than 2°C above pre-industrial levels, many coral reef systems will not survive. Unless carbon emissions are significantly reduced in the next decade, the consequences for global ecosystems will be severe.

17. Expressing attitudes, opinions, and mental states

The simple present is used with cognitive and mental state verbs — think, believe, know, understand, agree, doubt, suppose, assume, recognise — to express attitudes, opinions, and states of mind.

For example:

Most climate scientists agree that anthropogenic emissions are the primary driver of current warming trends. Many researchers doubt that the proposed carbon capture technologies can be deployed at the scale required.

18. Expressing sensory and perceptual states

The simple present is used with perception verbs — see, hear, smell, taste, feel — when they describe involuntary sensory states rather than deliberate actions.

For example:

The water smells of sulphur near the hydrothermal vents, indicating the presence of dissolved gases. The ice tastes clean and pure — it was formed from snowfall that fell more than 800,000 years ago.

19. Expressing possession and relationships

The simple present is used with possession verbs — have, own, belong, possess, contain — and relational verbs — include, involve, consist of, comprise — to describe possession and logical or structural relationships.

For example:

The Amazon basin contains approximately 10 per cent of all species of life currently known to science. The research team consists of twelve scientists, four engineers, and a dedicated data analysis unit.

20. Expressing logical necessity and inference

The simple present is used — particularly in formal and academic writing — to express logical inferences, deductions, and conclusions drawn from evidence.

For example:

The data suggests a clear and statistically significant correlation between rising temperatures and declining biodiversity. The geological record indicates that mass extinction events have occurred approximately five times in the history of complex life on Earth.

C. Signal Words and Phrases

Certain adverbs and adverbial expressions frequently accompany the simple present tense and help identify its use.

For example:

Global average temperatures generally rise by approximately 0.2°C per decade under current emission trajectories. The research vessel departs every January and returns in April after three months of sampling.

3. Usage in Context

• The simple present expresses permanent facts, scientific laws, and established truths that are always or generally true regardless of when they are stated.

The Sun releases energy through the process of nuclear fusion, converting hydrogen into helium at its core. Carbon dioxide absorbs infrared radiation and re-emits it in all directions, trapping heat in the Earth’s lower atmosphere.

• The simple present describes habits, routines, and repeated actions — things that happen regularly as a matter of course.

The research team collects water samples from the monitoring stations every Monday and Thursday throughout the year. Migratory birds return to the same breeding grounds each spring, navigating by the Earth’s magnetic field and the position of the Sun.

• The simple present is used with stative verbs — know, believe, contain, seem, consist, belong, prefer, understand — to describe ongoing states that are not normally expressed with continuous forms.

The deep ocean contains organisms that have never been observed in their natural habitat by human eyes. Scientists believe that the universe is approximately 13.8 billion years old, based on observations of the cosmic microwave background radiation.

• The simple present refers to scheduled future events — events fixed by a timetable, programme, or plan whose occurrence is certain.

The expedition departs on the fourteenth of March and is expected to return in early June after three months at sea. The international conference on biodiversity opens in Nairobi next Tuesday and runs for four days.

• In academic writing, the simple present is used to report the arguments, findings, and conclusions of studies and published works — even when those works were produced in the past.

Darwin argues in On the Origin of Species that natural selection is the primary mechanism driving evolutionary change. The study finds that species richness in coral reef ecosystems has declined by approximately 30 per cent since 1980.

• The simple present is used in instructions and procedural texts to describe each step of a process as a fact about what happens at that stage.

The researcher calibrates the instrument, records the baseline reading, and then introduces the sample into the chamber. The centrifuge separates the components of the sample by density, producing three distinct layers within approximately twenty minutes.

• The simple present is used in zero conditional sentences — expressing universal cause-and-effect relationships and scientific generalisations.

If the pressure drops below a certain threshold, dissolved gases come out of solution and form bubbles in the liquid. When a species loses access to its primary food source, its population declines rapidly unless alternative sources are available.

• The simple present is used in time clauses introduced by when, as soon as, before, after, until, once, and by the time — even when the main clause refers to the future.

Once the team finishes collecting the samples, it will return to the surface and begin the process of analysis. Before the expedition departs, every piece of equipment will be tested and calibrated to ensure accuracy in the field.

• The simple present is used in conditional clauses of the first type — where the condition is possible and the consequence is a likely future outcome.

If global temperatures rise by more than 1.5°C above pre-industrial levels, the consequences for coral reef ecosystems will be catastrophic. Unless deep-sea mining is properly regulated, irreversible damage will be done to ecosystems that took millions of years to develop.

• The simple present is used with cognitive verbs — think, believe, know, understand, agree, recognise, assume, doubt — to express opinions, attitudes, and mental states.

Most climate scientists agree that immediate and substantial reductions in carbon emissions are necessary to prevent catastrophic warming. Many researchers doubt that carbon capture technologies can be deployed at the scale required to make a meaningful difference.

• The simple present is used with perception verbs — see, hear, smell, taste, feel — when they describe involuntary sensory states rather than deliberate actions.

The water smells strongly of sulphur near the hydrothermal vents, indicating the presence of hydrogen sulphide gas. The ice feels dense and ancient — it was compacted under enormous pressure over hundreds of thousands of years.

• The simple present is used in performative utterances — declarations, promises, apologies, and formal announcements in which the act of speaking constitutes the performance of an action.

The committee hereby approves the proposal and authorises the release of funding for the next phase of the research project. I confirm receipt of the data and undertake to analyse it and report my findings within thirty days.

• The simple present is used in here + comes / goes and there + goes constructions to describe events happening at the moment of speaking.

Here comes the research vessel, right on schedule after three months of deep-ocean sampling. There goes the last known pair of the species — released into a protected marine reserve after years in captivity.

• The simple present is used in literary analysis, film synopses, and plot summaries to describe the actions and events of a narrative.

In the opening pages of The Voyage of the Beagle, Darwin describes the coastline of South America with a vividness that brings the landscape to life. In the documentary, the research team dives to the ocean floor and discovers an ecosystem unlike anything previously recorded.

• The simple present is used in formal and academic writing to introduce the purpose, structure, scope, and argument of a paper, report, or section.

This paper examines the relationship between ocean acidification and the decline of shellfish populations in the North Atlantic. The following section presents the results of the five-year monitoring programme and discusses their implications for conservation policy.

• The simple present expresses logical inferences, deductions, and conclusions drawn from evidence — particularly in scientific and analytical writing.

The data strongly suggests that the rate of permafrost thawing has accelerated significantly since the turn of the century. The fossil record indicates that the species first appeared approximately 300 million years ago during the Carboniferous period.

• The simple present is used with possession and relational verbs — have, own, contain, include, consist of, comprise, involve — to describe possession and logical or structural relationships.

The Amazon basin contains approximately 10 per cent of all species of life currently known to science. The research programme consists of three phases — data collection, laboratory analysis, and the preparation of the final report.

• The simple present of be — am, is, are — forms questions and negatives without do or does.

Is the Amazon the largest river in the world by discharge? Yes, it is — it carries approximately 20 per cent of all river water that reaches the oceans. The Nile is not the largest river by discharge — it is the longest, stretching approximately 6,650 kilometres from source to sea.

• The third person singular -s ending is obligatory in formal writing — omitting it is a significant grammatical error.

The glacier retreats every summer as temperatures rise above the freezing point of the ice. (not retreat) The research station monitors atmospheric carbon dioxide levels continuously throughout the year. (not monitor)

• Adverbs of frequency are placed between the subject and the main verb in most constructions — or after the verb to be.

Scientists regularly publish their findings in peer-reviewed journals to ensure the transparency and reproducibility of their results. The deep ocean is rarely studied as systematically as surface ecosystems, largely because of the extreme cost of deep-sea exploration.
