Should is a modal verb
with modal verbs there is only one form of it for every subject I
Should you should he should she should it should we should they should?
They all use should
We do not pronounce the L and the word should listen again
should
Should
Just like the other modal verbs there is never an S at the end of should
He should study no. This is not correct
He should study this is correct
After should we have the verb or more specifically the
base form of the infinitive
this means the infinitive without to
For example
The infinitive is to go
So the base form is just the NGO part
Instead of to study only study
Instead of to speak we only put speak after the modal verb
should
For example
You should to go. No, this is not correct
We don't use all of the infinitive. We need to remove the two part
So we say you should go
This is correct
He should waits
No, this is not correct
We don't conjugate the verb so no s is
necessary
We need the base form of the infinitive so we say
He should wait
This is correct
Some example sentences with should are
I should eat more vegetables
You should take an umbrella
He should go to the doctor she
Should apply for the job it should be fine
We should study more
They should wait until tomorrow
When do we use should in English
We use should to give advice a recommendation or a suggestion
This is to say that it is the right thing to do or the correct thing
You should see the new Star Wars movie, it's great. Yes. It is my recommendation
He should go to the dentist of his tooth still hurts
This is my advice or my suggestion
The test is next week
We should study for it now
This is a good idea a good suggestion
You should try that new restaurant on Main Street
Should can also be used to express
That a situation is likely or probable in the present or in the future
This is a type of expectation or prediction
Mary should be home now give her a call this means I expect her to be home right now
He should have the letter now I sent it last week
Our team should win the game on Saturday?
Because we have been training all month, so it is our expectation or prediction then this will happen
It should sunny tomorrow
Should can also be used to express an obligation that is not as strong as must
Sometimes should is used instead of must to make rules
orders or instructions sound more polite
This may appear more frequently on formal notices or on
information sheets
for example
Applications should be sent before the 30th
He should drive more carefully
Everyone should wear a seatbelt in a car
You should pay more attention in class
All of the above example sentences can have must
instead of should
Making the obligation stronger and less polite for example we can say
Applications must be sent before the 30th
With must it sounds more like an obligation and more formal
Should can also be used to say that something was
Expected in the past, but it didn't happen
Here we use should Plus have plus the past participle
This expresses the idea
That the subject did not fulfill their
Obligation in the past or did not act responsibly in the past
For example Anna is late. She should have arrived by now
It was her obligation to arrive here on time and she didn't do it I
Should have called Fred this morning, but I forgot
Fred expected me to call, but I didn't
You should have given your boss the report yesterday when he asked for it
Should
Can also be used to say that someone is not fulfilling an obligation
Or is not acting sensibly right now
Here we use should
plus B plus the verb ing
You should be wearing your seat belt
The person isn't wearing a seat belt right now. They are not fulfilling their obligation right now
We should be studying for the exam
Which means we're not studying right now, but we should be studying
Sometimes should is replaced by odd -
without a change in meaning
Note that or two
Sounds more formal and is used less frequently
You should go home now is
The same as you ought to go home now
using Auto
Sounds more formal
You can say
She should take her dog for more walks
or
She ought to take her dog for more walks. They both mean the same
The negative of should is
shouldn't or
should not
We almost always use the contraction shouldn't in spoken English
We use
Shouldn't to advise not to do something
Usually because it is bad or the wrong thing to do
You shouldn't eat that dessert if you were sick
This is my recommendation not to do something not to eat that dessert
She shouldn't buy that dress it's too big for her
You look tired you shouldn't work so much
He shouldn't talk to his boss like that
Notice how all of these sentences are about a recommendation or some advice
Not to do something
We do not use I think before
Shouldn't and the negative form
We use, I don't think in
negative and should an
affirmative
for example I
Think you shouldn't go there
This is not correct because we don't have the negative shouldn't after I think
instead we make the verb think negative and say I don't think you should go there a
Couple more examples. I don't think he should eat that
Notice the ThinkPad is in the negative form
Another example. I don't think we should start yet
We use should in questions when we want advice you want a recommendation
We want a suggestion
Let's look at this affirmative sentence I should go now
How can we change this to make it a question?
We change the order of the modal verb should
with the subject so the question becomes should
I go now a
couple more examples
Should I wear the green shirt, I'm asking for your advice or recommendation
We can also have the W words like what when y et cetera
before the modal verb
What should we do now?
This means what do you suggest?
