🙋♂️What's the difference between present continuous and simple past?

Present perfect signals an action that started in the past and continues now. Simple past tells of actions that started and finished in the past; they are not ongoing.

😵How do we know if it's past simple or present perfect?

Present perfect uses the auxiliary verb 'to be'; it describes actions that are ongoing. The simple past tense conjugates the verb in the past tense; it signals completed actions.

Past Simple vs Present Perfect

Even native English speakers struggle over whether they should use past simple or present perfect to describe events. Unfortunately, the answer isn't clear; it depends on many factors, including the type of English you speak. Here, you'll learn the difference between these two tenses, how to use them, and what makes them so different.

Past Simple vs. Present Perfect: What to Know

Past simple describes actions that started and finished in the past.
Present perfect describes actions that started in the past and continue today.
Recognise past simple by its time words: 'yesterday', 'last week', 'last night', and so on.
Present perfect has 'signal words', too: 'just', 'yet', 'ever', 'so far', and more.

What to Know About the Past Simple Tense

What it represents:

Actions that started and finished in the past.

Structure:

the past tense form of any verb

Example:

"I finished reading that book last night."

The simple past tense describes actions that started, happened, and finished in the past. Past simple sentences always include a time signal. Time signals may be a word or phrase that communicates the exact time the action took place. These are examples of time words:

yesterday
last week
in 2010

some time ago
when I was younger
the month before

last season
this morning
earlier today

How and When to Use the Past Simple Tense

Using past tenses in English calls for applying exact rules. Fortunately, of all the past tenses, simple past has the shortest, easiest list of rules to remember.

Use it to describe actions that started and finished in the past: "I went to Thailand last year."

May describe past habits or repeated actions: "I ate junk food every day when I was younger."

Should include time words (yesterday, last night, a year ago, etc.).

Is never used for ongoing or continuous actions.

Among my students, the past tense is one of their favourites to use. Thanks to its simple rules and easy structure, it's not hard to understand why. However, the past tense doesn't apply to every situation.

The Wide Usage of the Present Perfect Tense

What it represents:

Ongoing actions that started in the past and continue today.

Structure:

have + been + verb + '-ing'

Example:

"We have been doing things the same way for years."

English speakers use this tense to express a wide range of experiences, from ongoing actions to things that have never happened before. The song playing in the video and this quoted lyric examples of such usage.

I've been a miner for a heart of gold.
Neil Young

Like past-tense structures, present perfect tense uses time indicators. However, they are not strictly necessary and, when used, they are more general in nature.

just
already
yet
ever

never
so far
lately
recently

for
since
until then
up to now

When and How to Use Present Perfect

Of all the English language's present tenses, present perfect is one of the most used. In fact, we count nine different situations where using present perfect is necessary.

For ongoing actions and conditions: "They've been married for 10 years." "I've been working here for just a few months."

For life experiences that happened (or didn't) at any time: "I've never been to Europe." "I've seen that show three times already."

For recently completed actions: "We've already eaten dinner." "We've been to the new shopping centre."

For recently completed actions that impact the present moment: "I've finished cleaning my room." "He's broken his ankle. That's why he's not in school."

For past actions with current results: "I've lost my car keys; I have to get a new set." "She's become friends with them. Now, they do everything together."

For repeated actions: "They've eaten at that restaurant every week." "We've celebrated Easter at the beach every year."

To describe first experiences: "I've never had sushi before." "This is the best soup I've ever tasted!"

You'll note the occasional use of time words - 'ever/never', 'already', and 'every year'. As a rule, they're not strictly necessary, as they are when using some of the future tenses. However, in the sentences that have them, they're needed to add a loose time reference.

Past Simple vs. Present Perfect: Differences and Similarities

Up to now, we've examined each of these tenses on their own merits. Now, we look at them side-by-side.

Relating New Information

TV star Michael Barrymore has gone off the rails again.
Jonathan Hayter and Rick Hewett, journalists

When you're telling somebody new information, such as in the quote above, the present perfect is the tense to use. It helps you express the timeliness of the event; the logic is that it just happened, so it can't yet be in the past. By contrast, using the past tense presents the event as history, even if it happened recently. These sentences show this difference.

Jane has wrecked her car again.
Mickey has earned another A in maths.
My parents have gone on holiday.

Jane wrecked her car yesterday.
Mickey earned another A last week.
My parents went on holiday last month.

Specifying Time

Pro tip

The need for exact time helps define whether to use simple past or present perfect.

Of all the differences between these two tenses, time specification is the greatest¹. If you need to be exact about the time something happened, you must use simple past and include a time indicator. On the other hand, if the exact time the action took place isn't important, present perfect is the right tense to use.

Past simple

We saw that movie last night.
She woke up late today.
They went to Cancun last week.
I cooked breakfast this morning.

Present perfect

I have seen that movie too.
We've often woken up late.
They've been to Cancun before.
I've cooked breakfast a lot.

You'll note that all the sentences in the past simple column have exact time indicators. By contrast, the present perfect sentences have only general time indicators, even though they're not strictly necessary.

Cultural Differences

British English speakers use the present perfect tense to describe past actions they consider relevant to the present. By contrast, American English speakers typically use the past simple when they consider the action finished, regardless of their impacts on the present².

A Connection to the present

American English typically doesn't make strong connections between past actions and today's events.

What do such sentences look like in real life? Unless you're familiar with both British and American English, it sounds like one of these speakers is making a grave mistake.

British English

I'm going to uni for 6 years only to earn £27,000 per year?
They're taking care of Gran every day and she's left them nothing!
He's chasing after her for years and she's still ignoring him.

American English

I went to college for 6 years only to earn $32,000 per year?
They took care of Grandma every day and she left them nothing!
He chased after her for years and she still ignored him.

Cultural differences typically have a big impact on how English speakers use verb tenses; this comparison is a prime example of such. In fact, culture influences language usage in many other ways. This is one of the most challenging aspects of learning English as a second language.

Pro tip for English learners

Choose a type of English - British, American, Australian, etc. - and master its rules.
That way, you'll avoid making grammar mistakes on your English exams.

Present Perfect vs. Past Simple: Avoid These Mistakes

Adding a time signal to a present perfect sentence is, by far, the mistake my classes make the most often³. Note the difference between these sentences with definite time signals versus corrected sentences. Unnecessary time words are in parentheses; try saying the corrected sentences with and without them.

Mistakes I've heard

I've been to the doctor yesterday.
He's broken his arm last week.
I've had my car since two years ago.

Corrected

I've been to the doctor (already).
He's broken his arm.
I've had my car for two years.

Using the Wrong Tense

Using present perfect when the past tense is needed is the second biggest error category. These sentences and their corrections are perfect examples of this type of mistake.

Mistakes

They have been to Australia last month.
We've been to the cinema last night.
She has cooked breakfast this morning.

Corrected

They went to Australia last month.
We went to the cinema last night.
She cooked breakfast this morning.

This error works the other way, too. Using the past tense when the present perfect is the correct tense is just as big a mistake.

Mistakes

I took a shower already.
They never ate fish and chips.
He ate all the pizza; there's nothing left for me!

Corrected

I've taken a shower already.
They've never eaten fish and chips.
He's eaten all the pizza; there's nothing left for me!

Confusion With Present Perfect

The confusion doesn't just exist in present perfect vs. past simple. Using the wrong action verb in the present perfect tense isn't just grammatically incorrect. It also changes the sentence's meaning. Consider this sentence pair:

They've been to Sydney.

They've gone to Sydney.

Both are written with the present perfect tense, but the first sentence says that they went to Sydney and came back already. The second sentence says they're still in Sydney. Remember that present perfect describes past actions that impact current conditions. So, the choice of verb decides whether the action is in the past or ongoing.

As an English learner, you should be aware of mistakes such as these, but you shouldn't stress over making such mistakes. Even native speakers often use the wrong verb tense, whether in present perfect or any of the continuous tenses. The important thing is to revise and learn from these mistakes to improve your English skills.
