D. Grammar

Must and Should

Should

We use "should" to give, or ask for, advice or an opinion in the present:

• "I have a terrible stomachache." "You should go to the doctor's."
• "I haven’t heard from my father." "You should call him."
• "She's not happy with the salary offered." "She shouldn't accept the job."

Form

We use "should" / "shouldn't" + the infinitive of the main verb (without "to") 

Example 

I You He, She, It We They	should	do	more exercise.
		get	a new car.
	shouldn't (should not)	smoke.
		spend	so much money.

Should	I you he / she / it we they	get	more qualifications?
		wear	something different?

Must

"Must" is also used to talk about obligation and is used in written rules and instructions:

• You must submit your proposal by noon on 12th July.
• You must not use a calculator during the exam.

"Must" is also used to give a strong recommendation:

• You must tell him before it's too late.
• You mustn't be late for work on your first day.

The negative form, "mustn't" ("must not"), means that you are obliged or recommended not to do something.

Form

"must" or "mustn't" ("must not") + the infinitive of the verb (without "to") 

Example 

I You He / She / It We They	must mustn't	report	the theft to the police immediately.
		forget	to transfer the money.

Must

I you he / she / it we they

go?
