The third person imperative. Request
                                                                                Will you and would you, either with or without please, can be also introduced polite request.
Examples: Will you step this way. Will you please step this way.
Will you step this way please. Would you turn down the radio.
Would you please turn down the radio. Would you turn down the radio please.
Will you and would you in the example above can also  be used as a polite request even though the word  will you and  would you is not followed
with please. Do you mind and would you mind are also used for expressing polite
request. But these types can follow with please or not.
18
Examples: Do you mind waiting for a few minutes. Would you mind turning off the radio.
Note that mind is followed by the present participle or V1 + ing.
All  of  the  sentences  above  are  polite  request.  Even  though  all  the sentences  above  are  questioning  in  form,  they  usually  are  uttered  with
statement rising-falling intonation and written without a question mark.
19
If we put a question mark at the end of the sentence, it means that we need an
answer  from  the  listener.  But  the  sentences  above  are  request  where  the listener has to do what the speaker want in politeness. We can said that all of
them are polite request in the imperative that more show the politeness than the authority or we can said that this kind with polite imperative.

There  are  other  kinds  of  request  according  to  Hall.  The  verb  want  has borrowed a polite form from these polite imperatives, it is would like.
20
Examples: I want some coffee right now. I’d like some coffee right now.
From those sentences, it could be seen that want and would like are equivalents;  want  and  like  are  not.  Because  the  would  and  would  like  is
usually  contracted  I’d  like  many  students  learning  English  as  a  foreign language have difficulty with this polite pattern.
Examples: I like coffee. Coffee is pleasing to me. I’d like some coffee. I want some coffee.
In sum up, we can conclude that all of the sentences above are polite request in the imperative that show the politeness than the authority or we can
say that this kind is polite imperative. Beside  of  polite  request  or  polite  imperative,  the  imperative  will
seem much stronger than other imperative with a form with must.
21
It seems stronger because it will be used by a person in full authority like a superior in
the army or to ensure that an order is obeyed.  That statement  is  in line with Swan  who  said  that  “must  can  be  used  to  give  strong  advice  or  orders,  to
oneself or other people”.
22
The pattern for this is: Must + base form.
23
As in: Please do your homework.
You must do your homework. stronger than sentence above I really must stop smoking.
You must be here by 8 o’clock at the latest.

In  the  example  above,  we  can  see  the  differences  of  the  similar statement  in  the  first  and  second  example.  In  the  first  example  is  a  polite
request  and  the  second  sentence  that  used  must  is  more  stronger  that  has meaning as an obligation.
