Tenses (3) The simple present perfect “I have done…”

This tense is formed using the simple present of the verb ‘to have’ + the past participle I, you, we, they have seen, done, been, finished… he, she, it has seen, done, been, finished… It is used to connect the past and the present. It is especially used for finished actions in the past that are important in the present. Because of this, it is often used in news reports.

Tenses (2): The simple past and past progressive (or continuous)

Revision of present tenses

Habitual action, permanent or long-term state 1. I go to work by bus. 2. Japan is in Asia.

B. Present continuous or progressive:

Current, short-term action, changing situation 1. I am working hard on my project (short-term continuous action) 2. The weather is getting warmer (changing)

Past tenses: simple and progressive past

There is a similar situation in the past tense. (There are other past tenses than these too, but we’ll look at them another time.)

A. Simple past:

I, he, she, it went, worked, bought, saw, was you, we, they went, worked, bought, saw, were Used to talk about actions in the past; often used with an expression giving information about when the action took place: 1. Mr. Smith lived in Australia from 1999 to 2003. He went back there to visit friends last year. 2. I watched television until 9 p.m. yesterday evening, then I did my homework, had a bath and went to bed. This is also the past tense most often used in stories and other written accounts: * “The Rabbit … TOOK A WATCH OUT OF ITS WAISTCOAT- POCKET, and looked at it, and then hurried on.” (Lewis Carroll, “Alice’s Adventures in Wonderland”)

B. Past progressive

This is formed in the same way as the present progressive, except that it takes the simple past form of the verb ‘to be’: I, he, she, it was doing you, we, they were doing Used to talk about an action that was happening: * around a certain time in the past * before another action occurred 1. Policeman: What were you doing at 8 p.m. yesterday? Man: I was at home, watching television with my family. 2. I was dreaming I was on holiday when the alarm clock rang and I had to get up for work. 3. What were they saying about me before I arrived? Can be used for ‘setting the scene’ in a story (often in conjunction with an action in the simple past which interrupts the continuous action): The sun was shining, the birds were singing, and I was walking along the road thinking happily to myself about what I would do that day, when a huge monster suddenly appeared!

Tenses (1) – the present

There are two present tenses in English: the simple present and the present continuous or progressive.

Present continuous

This uses the appropriate form of the verb ‘to be’ followed by the infinitive + –ing. This -ing form is called the present participle (sometimes also the active, imperfect or progressive participle). I am working you, we, they are working he, she, it is working

Negative form

The negative form is made by adding the word ‘not’ between the part of the verb ‘to be’ and the present participle: I am not working you, we they are not working he, she it, is not working

Interrogative (question) form

This is made by reversing the order of the personal pronoun and verb: It is raining? -> Is it raining? You are working -> Are you working?

Simple present

This is formed from the infinitive of the verb, with an ‘s’ added in the third person singular (he, she, it): I, you, we, they work he, she, it works The negative form is made by adding ‘do not’ between the person and the verb. I, you, we, they do not work (this can be shortened to don’t in informal or spoken English) In addition, in the third person singular, we need to modify the endings of the verbs. ‘Do’ is the main verb in this sentence and takes the third-person singular form, ‘does’. ‘Work’ is now an auxiliary verb and loses the ‘s’. he, she, it does not work The imperative (command) form uses the verb without a personal pronoun: Go to bed! Please take a seat. Negative commands are made by inserting ‘do not’ before the verb. (Please) do not walk on the grass. Do not worry! / Don’t worry! Note to Japanese readers in particular: in English, it’s usual to add ‘please’ only when asking people to do something that may be inconvenient to them, or in more official situations. (Note that the ‘please’ is sometimes left off for reasons of space on signs.) Please wait here. Please take a seat. (Please) do not walk on the grass./(Please) keep off the grass. If you are using the imperative form to tell people to do something that they are likely to enjoy or benefit from, particularly in an informal situation, it’s much less common to add the ‘please’: Have a nice time! Have fun! Enjoy yourself! Feel free to ask if you need anything. (Please) help yourself to drinks and cake.

Interrogative (question) form

This is formed by adding the correct form of the verb ‘to do’ before the verb. You like ice-cream. -> Do you like ice-cream? For the third-person singular, ‘to do’ takes the form ‘does’ and what becomes the auxiliary verb loses its ‘s’ or ‘es’: It works. -> Does it work?

What is the difference between the two forms?

The present continuous is used for short-term or temporary states and changing situations: 1. What are you doing? I’m writing a report. 2. My car is making a strange noise. 3. The weather is getting better. 4. The world’s population is increasing. 5. Prices are increasing. The simple present is used for permanent or long-term states and things which occur repeatedly or frequently. 1. The earth revolves around the sun. 2. The JR Tohoku Line runs through Sendai. 3. We are Japanese. 4. I come to work by bus / I usually come to work by bus. 5. I play tennis every Wednesday. 6. Do you smoke? Some verbs are only normally used in the simple present form. Many of these are verbs describing thoughts, memories or feelings (believe, forget, remember, understand, like, love, hate, need, prefer, suppose, want, realise), but there are several others, too: belong, contain, matter, own. 1. Don’t worry – it doesn’t matter. 2. Do you remember your first day at school? 3. Do you realise that it is three years since we came here last? 4. I need some help. 5. I like milk but I hate cheese. 6. This pen belongs to me.
