Simple Tenses

The simple tenses are used to show permanent characteristics of people and events or what happens regularly, habitually or in a single completed action.

Continuous Tenses

The continuous tenses are used when talking about a particular point in time.

Perfect Tenses

Sometimes you need to give just a little bit more information about an action or state...and that is where the perfect tenses come in.

The perfect tenses are used when an action or situation in the present is linked to a moment in the past. It is often used to show things that have happened up to now but aren't finished yet or to emphasize that something happened but is not true anymore. When they end determines which of them you use.

Perfect tenses are never used when we say when something happened i.e. yesterday, last year etc. but can be used when discussing the duration of something i.e. often, for, always, since etc..

The Future Tenses

Discussing the future in English can seem complicated.The present simple, present continuous, present perfect simple and the present perfect continuous can all be used and often it is possible to use more than one structure, but have the same meaning.

Present Continuous Timeline

For example:

Q) "What are you doing?" A) "I'm building a website."

We also use the present continuous tense to talk about things that are happening around now but are temporary.

For example:

Q) "What are you doing these days?" A) "Unfortunately I'm working a lot."

It is also used to describe trends or situations that are happening but may be temporary.

For example:

"Nowadays more and more people are shopping on the Internet."

...and habitual actions (usually negative).

For example:

"He's always cleaning his car."

The present continuous tense can also be used to discuss future events:

Conditions: belong, cost, need, own, seem

Feelings: like, love, hate, want, wish

Beliefs: believe, feel, know, mean, remember, think, understand

We use the past continuous tense to describe a past action over a period of time.

Past Continuous Timeline

For example:

Q) "What were they doing yesterday?" A) "They were working all day."

It can be used to describe what someone was doing at a particular point in time.

For example:

Q) "What were you doing at 7.30 last night?" A) "I was watching television."

The past continuous can also be used to show that an activity frequently took place over a period of time.

Q) "What did you do on holiday?" A) "I went skiing a lot."

Often the past continuous is mixed with the past simple to show what was happening when something happened. The past continuous refers to the longer event and the simple past t
