Let us now learn about other types of Modal verbs.

 

SHALL, SHOULD, WILL, WOULD
Shall is used in the first person and �will� in all persons to express pure future.

 

Let us see these sentences:

1. I shall/will be twenty-five next birthday
2. Tomorrow will be Monday.

 

In both, the sentences, shall/will are been used to express the future. It is important to note that in present-day English, however, there is a growing tendency to use will in all persons. Shall is sometimes used in the second and third persons to express a command, a promise, or threat; as,

 

1. He shall not enter my house again.
2. Here shall is been used to express a Command.
3. You shall have a holiday tomorrow. (Promise)

 

Here shall is been used to express a promise.

 

Questions with shall I/we are used to ask the will of the person addressed; For example:

 

1. Shall I open the door?
2. Here it is been asked whether; Do you want me to open it ?; hence modal shall is used.
3. Which pen shall I buy?

 

Here advise has been sought for, hence modal shall is used.

 

WILL

 

Will is used to expressing one�s will for example

1. I will carry your books.
2. I will try to do better next time.

In the above sentences, the will is strong-stressed.

 

Will is also used to show Characteristic habits; for example

1. He will talk about nothing but films.
2. She will sit for hours listening to the wireless.

 

Will is also used to show Assumption or probability; for example

 

1. This will be the book you want, I suppose.
2. That will be the postman, I think.

 

Will is also used to indicate an invitation or a request; for example

1. Will you have tea?
2. Will you lend me your scooter?

 

It is important to remember that - Should and would are used as the past equivalents of shall and will; for example

 

1. I expected that I should get a first-class.
2. She said she would carry my books.

 

Should is used in all persons to express duty or obligation; for example
1. We should obey the laws.
2. You should keep your promise.

 

Word �should� is also used in clauses of condition, for example
1. If it should rain, they will not come.
2. If he should see me here, he will be annoyed.

 

Let us now see some important examples with containing modal �should and would�

 

(i) I should (or: would) like you to help her.
Here word �Should/would like' is a polite form of �want�.

 

(ii) Would you lend me your scooter, please?
Here note that �Would you ?� is more polite than �Will you ?�
