Should, Should is a modal verb, and we often use it English conversations to give advice, to recommend something or even suggest something.

If you are new to this channel, like, subscribe and click the bell, so that you don’t miss any of my new English lessons. Let’s get started.

We always use Should with all tenses and subjects. No matter what the subject or tense is, you will always use Should.

I should
You should
He should
She should
It should
We should
They should

However, you need to remember one thing, you cannot add an S at the end of should, as you do it with other verbs.

For example
The verb give can become gives OR take becomes takes, But we cannot add ‘s’ at the end of should.

He shoulds work harder. That’s wrong.
He should work harder. That’s the correct sentence.

Also, after should we always use the base form of the verb.

You never say –
You should to go now. That’s incorrect.
You should go now. That’s the correct sentence.

Here are two incorrect sentences, let me know in the comments, what’s the mistake in these sentences.

You shoulds study seriously, you have a test tomorrow.
They should waits for us.

Now, let’s understand When do we use SHOULD in English.

The first use of should is to give advice, recommendation or suggestion.
It’s used to say what is the right thing to do.

You should watch OZARK on Netflix if you like action web series.
You are recommending someone to watch Ozark; it’s a great series on Netflix. I loved all the seasons. Some great American Slang words.

He should see the doctor immediately if he’s complaining about chest pain.
It’s and advice, of Course if someone has a prolonged chest pain, they should see a doctor.

You should try the new Mexican restaurant on the main street.
It’s a suggestion.
See, how we used Should for an advice, recommendation and to suggest something. Why don’t you write some sentences for each one of them. I would love to read your comments.

The second use of Should is to Talk about a situation that is Likely to happen in the present or near future, Let’s look at some examples.

Ryan should be at the office by now, why don’t you give him a call?
Here you are predicting that Ryan will in the office any time soon.

They should have received the email; I sent it in the morning.
Again, you are sure that they have received the email, it will be there in their inbox.

The third use of should is to express an Obligation.

He should drive more carefully. Now you can also use MUST instead of should. Must is a strong word compared to Should. Must makes the sentence sound like a command or order. So, to soften your tone and sound polite, you can use Should instead of Must.

Everyone must wear a seat belt in a car. Sounds like an order, isn’t it? Instead, you can say-
Everyone should wear a seat belt in the car. It sounds like instruction and not an order.

You should pay your taxes on time to avoid penalty.

In all these sentences, you can replace Should with Must to make the Obligation stronger or less polite.

The fourth use of Should is to express that something was expected to happen in the past, but did not happen. Take a look at this sentence.

I should have called Ava this afternoon, but I forgot.
Note in such sentences we always use Should + have + Past participle form of the verb.
Here ‘called’ is the past participle of call. Something you were to do in the past, that is call Ava, but you forgot.

You should have told the truth when he asked for it.
Ryan is late. He should have arrived by now.

You can use should To say -someone hasn’t done something that they were suppose to do. In short they haven’t fulfilled an obligation. Such sentences are formed using Should + be+ verb in the ING form. Here are some example sentences.

YOu should be wearing your seat belt. The person is not wearing one right now. You are asking them to behave sensibly and wear a seat belt.
Enough of excuses, you should be submitting your report by tomorrow morning.
Here, the boss is asking you to be responsible and submit the report. If you notice in both the sentences someone has not
Those were the five uses of Should, now let’s learn how to use Shouldn’t.

The negative of should is Should not and the contracted form is shouldn’t. We usually use shouldn’t in spoken English as it sounds more natural in conversations.

Shouldn’t is use to advise someone not to do something because it could be bad or wrong to do it.

You shouldn’t go to the office if you are sick.
It’s a recommendation, not to goto the office because you will be stressed and get more sick.

You shouldn’t spend your whole salary on that phone.
You shouldn’t stop practicing English if you want to get fluent faster.
All these sentences are advices or recommendations about NOT to do something.

You can also use the sentence structure Think + Should
Look at this sentence –

I think you shouldn’t go to the party. Do you think this sentence is correct, think about it for a moment.
This sentence is incorrect. As a rule we do not use I think + Shouldn’t. Instead we add don’t before think and make it negative.
I don’t think you should go to the party. That’s the correct sentence. Keep this in mind, do not say I Think you shouldn’t always say – I don’t think you should. I hope you got it.

And lastly let’s look at how to use Should in Questions.
We use should in questions to seek someone’s advice, recommendation or suggestion.
Take a look at this sentence –

I should leave now, it’s late.
It’s a positive statement, how can we change it into a question, it’s simple. Just change the order of the modal verb should with the Subject.

Should I leave now, it’s late?

Should I wear the black dress for the party? – Here, I am asking for your advise or recommendation.

You can also use question words such as What, when, Why etc before the modal verb.

What should we do now?
Why should he lie to me?

That’s all for today, I hope, now you know how to the Modal verb Should correctly in English sentences. Practice making sentences with all the uses of Should. I will see you soon with one more English lesson, until then keep learning, keep practising English. Bye.
