present continouos

Present Continuous

When we talk about events that are actually happening now, we use the present continuous tense. This is formed by using the stem of the verb and adding -ing to the end, for example the verb "work" becomes "working". In some cases you need to alter the spelling a bit for example the verb "die" becomes "dying".

Present Continuous Timeline

Present Continuous Tense 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:
Note:-
The present continuous is usually used with doing verbs (verbs of action) not with verbs of state. The following verbs are not used in the continuous form:-
Conditions: belong, cost, need, own, seem
Feelings: like, love, hate, want, wish
Beliefs: believe, feel, know, mean, remember, think, understand

Countable and Uncountable

Countable nouns are easy to recognize. They are things that we can count. For example: "pen". We can count pens. We can have one, two, three or more pens. Here are some more countable nouns:
  • dog, cat, animal, man, person
  • bottle, box, litre
  • coin, note, dollar
  • cup, plate, fork
  • table, chair, suitcase, bag
Countable nouns can be singular or plural:
  • My dog is playing.
  • My dogs are hungry.
We can use the indefinite article a/an with countable nouns:
  • A dog is an animal.
When a countable noun is singular, we must use a word like a/the/my/this with it:
  • I want an orange. (not I want orange.)
  • Where is my bottle? (not Where is bottle?)
When a countable noun is plural, we can use it alone:
  • I like oranges.
  • Bottles can break.
We can use some and any with countable nouns:
  • I've got some dollars.
  • Have you got any pens?
We can use a few and many with countable nouns:
  • I've got a few dollars.
  • I haven't got many pens.
Uncountable nouns are substances, concepts etc that we cannot divide into separate elements. We cannot "count" them. For example, we cannot count "milk". We can count "bottles of milk" or "litres of milk", but we cannot count "milk" itself. Here are some more uncountable nouns:
  • music, art, love, happiness
  • advice, information, news
  • furniture, luggage
  • rice, sugar, butter, water
  • electricity, gas, power
  • money, currency
We usually treat uncountable nouns as singular. We use a singular verb. For example:
  • This news is very important.
  • Your luggage looks heavy.
We do not usually use the indefinite article a/an with uncountable nouns. We cannot say "an information" or "a music". But we can say a something of:
  • a piece of news
  • a bottle of water
  • a grain of rice
We can use some and any with uncountable nouns:
  • I've got some money.
  • Have you got any rice?
We can use a little and much with uncountable nouns:
  • I've got a little money.
  • I haven't got much rice.
Here are some more examples of countable and uncountable nouns:

Should and Shouldn't




 Use

  • We use should and shouldn't to give advice or to talk about what we think is right or wrong.
  • You should means something like I think it is a good idea for you to do it.
  • You shouldn't means something like I think it is a bad idea for you to do it.
  • Should is used to express the opinion of a speaker and often follows I thinkor I don't think.

Examples

     You look tired. I think you should take a few days off.

     Alice works very long hours. She should to talk to her boss.

     - I have an English test tomorrow.
     - I shouldn't worry if I were you. You have worked really hard.

     - I never have enough money.
     - I don't think you should go out so much.



Should - Quick Grammar Note

To give advice to someone you can also say:
  • I should do it if I were you.
  • I shouldn't be so rude, if I were you.

When you regret not doing something in the past, you can say:
  • I shouldn't have spoken to him like that.
  • I should have apologized earlier.

Prepositions: In, On, and At (with specific times and places)
The prepositions inon, and at can be used to indicate time and place. Notice how they are used in the following situations:

In many languages, there is only one preposition for the above situations. In English there are three. Just remember that in usually indicates the "largest" time or place, and at usually indicates the "smallest" time or place.

Prepositions with articles and locations

When talking about locations, use at to indicate the general vicinity or area, and in to indicate inside the building, enclosed area, etc. For example:

at the post office/bank (general)

in the post office/bank (inside the building)
at the zoo (visitors, general area)

The present simple


subject+auxiliary verb+main verb
  do base
There are three important exceptions:
  1. For positive sentences, we do not normally use the auxiliary.
  2. For the 3rd person singular (he, she, it), we add s to the main verb or es to the auxiliary.
  3. For the verb to be, we do not use an auxiliary, even for questions and negatives.
Look at these examples with the main verb like:
 subjectauxiliary verb main verb 
+I, you, we, they likecoffee.
He, she, it likescoffee.
-I, you, we, theydonotlikecoffee.
He, she, itdoesnotlikecoffee.
?DoI, you, we, they likecoffee?
Doeshe, she, it likecoffee?
Look at these examples with the main verb be. Notice that there is no auxiliary:
 subjectmain verb  
+Iam French.
You, we, theyare French.
He, she, itis French.
-Iamnotold.
You, we, theyarenotold.
He, she, itisnotold.
?AmI late?
Areyou, we, they late?
Ishe, she, it late?

How do we use the Present Simple Tense?

We use the present simple tense when:
  • the action is general
  • the action happens all the time, or habitually, in the past, present and future
  • the action is not only happening now
  • the statement is always true
John drives a taxi.
pastpresentfuture

It is John's job to drive a taxi. He does it every day. Past, present and future.
Look at these examples:
  • I live in New York.
  • The Moon goes round the Earth.
  • John drives a taxi.
  • He does not drive a bus.
  • We meet every Thursday.
  • We do not work at night.
  • Do you play football?
Note that with the verb to be, we can also use the present simple tense for situations that are not general. We can use the present simple tense to talk about now. Look at these examples of the verb "to be" in the present simple tense - some of them are general, some of them are now:
Am I right?
Tara is not at home.
You are happy.
pastpresentfuture

The situation is now.
 
I am not fat.
Why are you so beautiful?
Ram is tall.
pastpresentfuture

The situation is general. Past, present and future.
