MIXED TENSES
Present Simple or Present Continuous?
Introduction
The simple present tense is often confused with the present continuous tense. This page will explain when to use each one.
1. The simple present tense
The simple present tense is used for two main types of action:
| Habits | Actions which happen regularly (for example, every day or every week) |
| States | Things which do not often change (for example, opinions and conditions) |
Some examples will help to make this clearer:
| Type of action | Examples | Explanations |
| Habit | Young-Mi goes to class every day. | “Every day” is a habit. |
| It rains a lot in Vancouver. | This means that it rains often. | |
| Santos always talks about his family. | “Always” means this is a habit. | |
| Jerry spends Christmas with his parents. | This implies that he spends Christmas with his parents every year. | |
| State | Bianca lives in Florida. | This is a state, because it doesn’t change. |
| Jean-Paul has red hair. | Someone’s hair colour doesn’t usually change. | |
| Martin likes chocolate. | When we like something, usually we will always like it. | |
| Anna believes in God. | Beliefs and opinions are states. They don’t often change. |
2. The present continuous tense
The present continuous tense is used for two main types of action:
| A temporary action happening now | Something which is going on right now (but it will stop in the future) |
| A definite plan for the future | Something we intend to do, usually in the near future |
Here are some examples:
| Type of action | Examples | Explanations |
| Temporary action happening right now | John is winning the game. | Right now, John is winning, but the game isn’t finished yet. |
| It’s raining outside. | It’s raining right now (but it may stop soon). | |
| Soraya’s working in the library. | She’s working there right now. | |
| Sihol is spending Christmas with his family. | He’s spending Christmas with his family right now, this year. (Maybe next year he won’t.) | |
| Definite plan for the future | I’m playing soccer tomorrow. | This plan is already arranged and definite. |
| Sarah’s leaving for San Francisco on Friday. | She has probably already bought her ticket. | |
| The Olympics are taking place here next year. | This is already certain. | |
| I’m having a party next week. | All the plans have been made. |

STATIVE VERBS
Some English verbs, which we call state, non-continuous or stative verbs, aren’t used in continuous tenses (like the present continuous, or the future continuous). These verbs often describe states that last for some time. Here is a list of some common ones:
Stative (or State) Verb List
| like | know | belong |
| love | realise | fit |
| hate | suppose | contain |
| want | mean | consist |
| need | understand | seem |
| prefer | believe | depend |
| agree | remember | matter |
| mind | recognise | see |
| own | appear | look (=seem) |
| sound | taste | smell |
| hear | astonish | deny |
| disagree | please | impress |
| satisfy | promise | surprise |
| doubt | think (=have an opinion) | feel (=have an opinion) |
| wish | imagine | concern |
| dislike | be | have |
| deserve | involve | include |
| lack | measure (=have length etc) | possess |
| owe | weigh (=have weight) |
A verb which isn’t stative is called a dynamic verb, and is usually an action.
Some verbs can be both stative and dynamic:
| Be |
be is usually a stative verb, but when it is used in the continuous it means ‘behaving’ or ‘acting’
|
| Think |
|
| Have |
|
| See |
|
| Taste |

NARRATIVE TENSES
PAST SIMPLE, PAST PROGRESSIVE, PAST PERFECT AND PAST PERFECT PROGRESSIVE.
THE PAST SIMPLE IS USED:
- For a complete action that took place at a definite time in the past. The time is either mentioned or implied.
- For habitual or repeated actions in the past.
- For completed actions that took place one after the other in the past.
I bought this suit last week
She always came late to the office.
I arrived home late last night, had a glass of milk and went straight to bed.
- TIME EXPRESSIONS: Yesterday, then, last night/week/month, ago etc
THE PAST PROGRESSIVE IS USED:
- For an action that was in progress at a definite time in the past
- For an action that was happening when another one interrupted it. The longer action is in the past progressive and the shorter one is in the past simple.
- For two or more actions happening at the same time in the past.
They were watching the news at 8:45 last night.
She was sweeping the floor when she found a coin.
While I was doing the washing up, my mother was cooking.

PAST PERFECT SIMPLE IS USED:
- For a past action that was completed before another past action. We use the Past Perfect simple for the first action and the past simple for the second action.
- For an action that was completed before a definite time in the past.

The firemen looked exhausted. They had been trying to put out the fire for six hours.
- TIME EXPRESSIONS: When, for, since, after, before, how long etc..
When we use BEFORE or AFTER to describe the first two actions that happened in the past, we can use the past simple instead of the Past perfect simple.
The students had come/ come before the teacher arrived.

RELATIVE CLAUSES 
relative pronoun |
use |
example |
|---|---|---|
| who | subject or object pronoun for people | I told you about the woman who lives next door. |
| which | subject or object pronoun for animals and things | Do you see the cat which is lying on the roof? |
| which | referring to a whole sentence | He couldn’t read which surprised me. |
| whose | possession for people animals and things | Do you know the boy whose mother is a nurse? |
| whom | object pronoun for people, especially in non-defining relative clauses (in defining relative clauses we colloquially prefer who) | I was invited by the professor whom I met at the conference. |
| that | subject or object pronoun for people, animals and things in defining relative clauses (who or which are also possible) | I don’t like the table that stands in the kitchen. |
Subject Pronoun or Object Pronoun? 
Subject and object pronouns cannot be distinguished by their forms – who, which, that are used for subject and object pronouns. You can, however, distinguish them as follows:
If the relative pronoun is followed by a verb, the relative pronoun is a subject pronoun. Subject pronouns must always be used.
the apple which is lying on the table
If the relative pronoun is not followed by a verb (but by a noun or pronoun), the relative pronoun is an object pronoun. Object pronouns can be dropped in defining relative clauses, which are then called Contact Clauses.
the apple (which) George lay on the table
Relative Adverbs
A relative adverb can be used instead of a relative pronoun plus preposition. This often makes the sentence easier to understand.
This is the shop in which I bought my bike.
→ This is the shop where I bought my bike.
| relative adverb | meaning | use | example |
|---|---|---|---|
| when | in/on which | refers to a time expression | the day when we met him |
| where | in/at which | refers to a place | the place where we met him |
| why | for which | refers to a reason | the reason why we met him |
Defining Relative Clauses
Defining relative clauses (also called identifying relative clauses or restrictive relative clauses) give detailed information defining a general term or expression. Defining relative clauses are not put in commas.
Imagine, Tom is in a room with five girls. One girl is talking to Tom and you ask somebody whether he knows this girl. Here the relative clause defines which of the five girls you mean.
Do you know the girl who is talking to Tom?
Defining relative clauses are often used in definitions.
A seaman is someone who works on a ship.
Object pronouns in defining relative clauses can be dropped. (Sentences with a relative clause without the relative pronoun are called Contact Clauses.)
The boy (who/whom) we met yesterday is very nice.
Non-Defining Relative Clauses
Non-defining relative clauses (also called non-identifying relative clauses or non-restrictive relative clauses) give additional information on something, but do not define it. Non-defining relative clauses are put in commas.
Imagine, Tom is in a room with only one girl. The two are talking to each other and you ask somebody whether he knows this girl. Here the relative clause is non-defining because in this situation it is obvious which girl you mean.
Do you know the girl, who is talking to Tom?
Note: In non-defining relative clauses, who/which may not be replaced with that.
Object pronouns in non-defining relative clauses must be used.
Jim, who/whom we met yesterday, is very nice.

PRESENT PERFECT VS SIMPLE PAST
Use
In British English, the use of Simple Past and Present Perfect is quite strict. As soon as a time expression in the past is given, you have to use Simple Past. If there are no signal words, you must decide if we just talk about an action in the past or if its consequence in the present is important.
Note that the following explanations and exercises refer to British English only. In American English, you can normally use Simple Past instead of Present Perfect. We cannot accept this in our exercises, however, as this would lead to confusions amongst those who have to learn the differences.
Certain time in the past or just / already / yet?
Do you want to express that an action happened at a certain time in the past (even if it was just a few seconds ago) or that an action has just / already / not yet happened?
| Simple Past | Present Perfect Simple |
|---|---|
certain time in the past
|
just / already / not yet
|
Certain event in the past or how often so far?
Do you want to express when a certain action took place or whether / how often an action has happened till now?
| Simple Past | Present Perfect Simple |
|---|---|
certain event in the past
|
whether / how often till now
