In today's lesson we shall learn how to use SHOULD. Like CAN SHOULD is also modal verb like other modal verbs. It does not contain any meaning instead, it is used before a verb and starts expressing its meaning.
Remember that all modal verbs do not contain any meaning what all of them do is that when they are combined with a verb, they change the idea of that verb. It does not mean that modals change the meaning of a verb.
e.g. The verb EAT shall keep the same meaning but when combined with different modals its idea changes.
e.g. You can eat 10 bananas a day. (here CAN (modal verb) changes the idea of (EAT) and adds the sense or idea of ability.
Now, observe this sentence.
You should eat 10 bananas a day.
The whole sentence is same but the with different modal verb (SHOULD) expressing the idea or sense of mild suggestion.
Should is a modal verb and is used to express mild suggestions or advice.
e.g. My rooms is dirty , I should clean it.
You look tired, you should rest.
She looks sick, she should see a doctor.
In all of the above sentences you can observe that should is expressing a mild suggestion, a soft advice . In other words, SHOULD expresses that it is a good idea or a good advice.
We always use SHOULD with first form of a verb. We do not use (TO) or add (S/ES) with verb.
e.g. Correct : He should study with great concentration
Incorrect : He should to study with great concentration
Incorrect : He should studies with great concentration
Incorrect : He should plays actively
Contraction of Should with NOT
You can easily contract should with not -----> Should + not = Shouldn't
Structures of Should
Affirmative : Subject + Should + 1st Form of a Verb + Object
We should help the poor
She should come on time.
Negative : Subject + Should + not + 1st Form of a Verb + Object
We should not help the poor
She should not come on time
Interrogative : Should + Subject +1st Form of a Verb + Object?
