He wants. Does he want? He does not want.

Present Continuous or Present Progressive

Present Continuous or Present Progressive Verb Form

1. Present continuous, form

The present continuous of any verb is composed of two parts - the present tense of the verb to be + the present participle of the main verb.
(The form of the present participle is: base+ing, e.g. talking, playing, moving, smiling)
Affirmative
Subject
+ to be
+ base+ing
she
is
talking



Negative
Subject
+ to be + not
+ base+ing
she
is not (isn't)
talking



Interrogative
to be
+ subject
+ base+ing
is
she
talking?

Example: to go, present continuous

Affirmative
Negative
Interrogative
I am going
I am not going
Am I going?
You are going
You aren't going.
Are you going?
He, she, it is going
He, she, it isn't going
Is he, she, it going?
We are going
We aren't going
Are we going?
You are going
You aren't going
Are you going?
They are going
They aren't going
Are they going?
Note: alternative negative contractions: I'm not going, you're not going, he's not going etc.

2. Present Continuous, function

As with all tenses in English, the speaker's attitude is as important as the time of the action or event. When someone uses the present continuous, they are thinking about something that is unfinished or incomplete.
The present continuous is used:
·          to describe an action that is going on at this moment e.g. 
You are using the Internet. You are studying English grammar.
·         to describe an action that is going on during this period of time or a trend, e.g.
Are you still working for the same company? More and more people are becomingvegetarian.
·         to describe an action or event in the future, which has already been planned or prepared (See also 'Ways of expressing the future) e.g. 
We're going on holiday tomorrow. I'm meeting my boyfriend tonight. Are they visitingyou next winter?
·         to describe a temporary event or situation, e.g. 
He usually plays the drums, but he's playing bass guitar tonight
. The weather forecast was good, but it's raining at the moment.
·         with 'always, forever, constantly', to describe and emphasise a continuing series of repeated actions, e.g. 
Harry and Sally are always arguing! You're forever complaining about your mother-in-law!
BE CAREFUL! Some verbs are not used in the continuous form - see below.
3. Verbs that are not normally used in the continuous form
The verbs in the list below are normally used in the simple form, because they refer tostates, rather than actions or processes:
List of common verbs normally used in simple form:
Senses / Perception
feel*, hear, see*, smell, taste
Opinion
assume, believe, consider, doubt, feel (= think), find (= consider), suppose, think*
Mental states
forget, imagine, know, mean, notice, recognise, remember, understand
Emotions / desires
envy, fear, dislike, hate, hope, like, love, mind, prefer, regret, want, wish
Measurement
contain, cost, hold, measure, weigh
Others
look (=resemble), seem, be (in most cases), have (when it means to possess)*
Notes:
·          'Perception' verbs (see, hear, feel, taste, smell) are often used with 'can': e.g.
I can see...
·         * These verbs may be used in the continuous form but with a different meaning, compare:
·          This coat feels nice and warm. (= your perception of the coat's qualities)
·          John's feeling much better now (= his health is improving)
·          She has three dogs and a cat. (=possession)
·          She's having supper. (= She's eating)
·         I can see Anthony in the garden (= perception)
·          I'm seeing Anthony later (= We are planning to meet)

Examples

·         I wish I was in Greece now.
·         She wants to see him now.
·         I don't understand why he is shouting.
·         I feel we are making a mistake.
·         This glass holds half a litre.

 

 

 

Present Perfect Verb Tense

PRESENT PERFECT

1. Present Perfect - Form

The present perfect of any verb is composed of two elements : the appropriate form of the auxiliary verb to have (present tense), plus the past participle of the main verb. The past participle of a regular verb is base+ed, e.g. played, arrived, looked. For irregular verbs, see the Table of irregular verbs in the section called 'Verbs'.
Affirmative
Subject
to have
past participle
She
has
visited
Negative
Subject
to have + not
past participle
She
hasn't
visited
Interrogative
to have
subject
past participle
Has
she
visited..?
Interrogative negative
to have + not
subject
past participle
Hasn't
she
visited...?
Example: to walk, present perfect
Affirmative
Negative
Interrogative
I have walked
I haven't walked
Have I walked?
You have walked
You haven't walked
Have you walked?
He, she, it has walked
He, she, it hasn't walked
Has he,she,it walked
We have walked
We haven't walked
Have we walked?
You have walked
You haven't walked
Have you walked?
They have walked
They haven't walked
Have they walked?

2. Present perfect, function

The Present Perfect is used to indicate a link between the present and the past. The time of the action is before now but not specified, and we are often more interested in the resultthan in the action itself.
BE CAREFUL! There may be a verb tense in your language with a similar form, but the meaning is probably NOT the same.
The Present Perfect is used to describe:
1.    An action or situation that started in the past and continues in the present. Example: I have lived in Bristol since 1984 (= and I still do.)
2.     An action performed during a period that has not yet finished. Example: Shehas been to the cinema twice this week (= and the week isn't over yet.)
3.     A repeated action in an unspecified period between the past and now. Example: We have visited Portugal several times.
4.     An action that was completed in the very recent past, (expressed by 'just'). Example: I have just finished my work.
5.     An action when the time is not important. Example: He has read 'War and Peace'. (the result of his reading is important)
Note: When we want to give or ask details about when, where, who, we use the simple past. Example: He read 'War and Peace' last week.

Examples:

1. Actions started in the past and continuing in the present.
·          They haven't lived here for years.
·          She has worked in the bank for five years.
·          We have had the same car for ten years.
·         Have you played the piano since you were a child?
2. When the time period referred to has not finished.
·         I have worked hard this week.
·          It has rained a lot this year.
·          We haven't seen her today.
3. Actions repeated in an unspecified period between the past and now.
·          They have seen that film six times.
·          It has happened several times already.
·          She has visited them frequently.
·          We have eaten at that restaurant many times.
4. Actions completed in the very recent past (+just).
·         Have you just finished work?
·          I have just eaten.
·          We have just seen her.
·         Has he just left?
5. When the precise time of the action is not important or not known.
·          Someone has eaten my soup!
·         Have you seen 'Gone with the Wind'?
·         She's studied Japanese, Russian and English.

 

Present perfect + ever,never,already,yet

PRESENT PERFECT + ever, never, already, yet

The adverbs ever and never express the idea of an unidentified time before now e.g. Have youever visited Berlin?

'Ever' is used

·          in questions. e.g. 
Have you ever been to England?
Has she ever met the Prime Minister?
·         in negative questions e.g.
Haven't they ever been to Europe?
Haven't you ever eaten Chinese food?
·          and in negative statements using the pattern nothing.......ever,nobody.......ever e.g.
Nobody
 has ever said that to me before.
Nothing like this has ever happened to us.
·         'Ever' is also used with 'The first time.... e.g.
It's the first time (that) I've ever eaten snails. 
This is the first time I've ever been to England.

'Never' means at no time before now, and is the same asnot ..... ever:

·         I have never visited Berlin
BE CAREFUL!
You must not use never and not together:
·         I haven't never been to Italy.
·         I have never been to Italy.

Position

'Ever' and 'never' are always placed before the main verb (past participle).

Already and yet

Already

refers to an action that has happened at an unspecified time before now. It suggests that there is no need for repetition, e.g.
a. I've already drunk three coffees this morning. (and you're offering me another one!)
b. Don't write to John, I've already done it.
It is also used in questions:
·         Have you already written to John?
·         Has she finished her homework already?

Position

already can be placed before the main verb (past participle) or at the end of the sentence:
·         I have already been to Tokyo.
·          I have been to Tokyo already.

Yet

is used in negative statements and questions, to mean (not) in the period of time between before now and now, (not) up to and including the present. e.g.
·          Have you met Judy yet?
·          I haven't visited the Tate Gallery yet.
·          Has he arrived yet?
·          They haven't eaten yet.

Position

Yet is usually placed at the end of the sentence.

Present Perfect of Simple Past?

How to choose between the Present Perfect and Simple Past Tenses

·         Always use the Present Perfect when the time is not important, or not specified.
·          Always use the Simple Past when details about the time or place are specified or asked for.
Compare:
Present Perfect
Simple Past
I have lived in Lyon.
I lived in Lyon in 1989.
They have eaten Thai food.
They ate Thai food last night.
Have you seen 'Othello'?.
Where did you see 'Othello'?
We have been to Ireland.
When did you go to Ireland?
There is also a difference of attitude that is often more important than the time factor.
·         "What did you do at school today?" is a question about activities, and considers the school day as finished.
·         "What have you done at school today?" is a question about results - "show me", and regards the time of speaking as a continuation of the school day.

Present Perfect + for and since

PRESENT PERFECT + for, since

Using the present perfect, we can define a period of time before now by considering its duration,with for + a period of time, or by considering its starting point, with since + a point in time.

For + a period of time

·         for six years, for a week, for a month, for hours, for two hours.
·          I have worked here for five years.

Since + a point in time

·         since this morning, since last week, since yesterday,
·         since I was a child, since Wednesday, since 2 o'clock.
·          I have worked here since 1990.

present perfect with for

·          She has lived here for twenty years.
·          We have taught at this school for a long time.
·          Alice has been married for three months.
·          They have been at the hotel for a week.

present perfect with since

·          She has lived here since 1980.
·          We have taught at this school since 1965
·          Alice has been married since March 2nd.
·          They have been at the hotel since last Tuesday.

Note:

·         For and since can both be used with the past perfect.
·         Since can only be used with perfect tenses, for can also be used with the simple past.

 

Present Perfect Continuous

 

 

 

PRESENT PERFECT CONTINUOUS

Present Perfect Continuous, Form

The present perfect continuous is made up of two elements:
1.     the present perfect of the verb 'to be' (have/has been), and
2.     the present participle of the main verb (base+ing).
Subject
has/have been
base+ing
She
has been
swimming

Affirmative
She has been / She's been
running
Negative
She hasn't been
running
Interrogative
Has she been
running?
Interrogative negative
Hasn't she been
running?

Example: to live, present perfect continuous

Affirmative
Negative
Interrogative
I have been living
I haven't been living
Have I been living?
You have been living
You haven't been living
Have you been living?
He, she, it has been living
He hasn't been living
Has she been living?
We have been living
We haven't been living
Have we been living?
You have been living
You haven't been living
Have you been living?
They have been living
They haven't been living
Have they been living?

Present perfect continuous, function

The present perfect continuous refers to an unspecified time between 'before now' and 'now'. The speaker is thinking about something that started but perhaps did not finish in that period of time. He/she is interested in the process as well as the result, and this process may still be going on, or may have just finished.

Examples

1. Actions that started in the past and continue in the present.
·          She has been waiting for you all day (=and she's still waiting now).
·          I've been working on this report since eight o'clock this morning (=and I still haven't finished it).
·          They have been travelling since last October (=and they're not home yet).
2. Actions that have just finished, but we are interested in the results:
·          She has been cooking since last night (=and the food on the table looks delicious).
·          It's been raining (= and the streets are still wet).
·         Someone's been eating my chips (= half of them have gone).

Verbs without continuous forms

With verbs not normally used in the continuous form, use the present perfect simple. See list of these verbs under 'Present Continuous':
·         I've wanted to visit China for years.
·         She's known Robert since she was a child.
·         I've hated that music since I first heard it.
·         I've heard a lot about you recently.
·         We've understood everything we've heard this morning.
