18. MODAL VERBS
Modal verbs are special verbs which behave very
differently from normal verbs. Here are some important
differences:
1. Modal verbs do not take "-s" in the third person.
Examples:
He can speak Chinese.
She should be here by 9:00.
19. 2. You use "not" to make modal verbs negative, even in
Simple Present and Simple Past.
Examples:
He should not be late.
They might not come to the party.
3. Many modal verbs cannot be used in the past tenses
or the future tenses.
Examples:
He will can go with us. Not Correct
She musted study very hard. Not Correct
20. Can
"Can" is one of the most commonly used modal
verbs in English. It can be used to express ability or
opportunity, to request or offer permission, and to
show possibility or impossibility.
Examples:
I can ride a horse. (ABILITY)
We can stay with my brother when we are in
Paris. (OPPORTUNITY)
She cannot stay out after 10 PM. (PERMISSION)
Can you hand me the stapler? (REQUEST)
Any child can grow up to be president. (POSSIBILITY)
21. Could
"Could" is used to express possibility or past ability as
well as to make suggestions and requests. "Could" is
also commonly used in conditional sentences as the
conditional form of "can."
Examples:
Extreme rain could cause the river to flood the
city. possibility
Nancy could ski like a pro by the age of 11. past ability
You could see a movie or go out to dinner. suggestion
Could I use your computer to email my boss? request
We could go on the trip if I didn't have to work this
weekend. conditional
22. May
"May" is most commonly used to express possibility. It
can also be used to give or request permission,
although this usage is becoming less common.
Examples:
Cheryl may be at home, or perhaps at
work. possibility
Johnny, you may leave the table when you have
finished your dinner. give permission
May I use your bathroom? request permission
23. Might
"Might" is most commonly used to express possibility. It is
also often used in conditional sentences. English speakers
can also use "might" to make suggestions or requests,
although this is less common in American English.
Examples:
Your purse might be in the living room. POSSIBILITY
If I didn't have to work, I might go with you. CONDITIONAL
You might visit the botanical gardens during your
visit. SUGGESTION
Might I borrow your pen? REQUEST
24. Shall
"Shall" is used to indicate future action. It is most
commonly used in sentences with "I" or "we," and is often
found in suggestions, such as "Shall we go?" "Shall" is also
frequently used in promises or voluntary actions. In formal
English, the use of "shall" to describe future events often
expresses inevitability or predestination.
Examples:
Shall I help you? SUGGESTION
I shall never forget where I came from. PROMISE
He shall become our next king. PREDESTINATION
I'm afraid Mr. Smith shall become our new
director. INEVITABILITY
25. Should
"Should" is most commonly used to make
recommendations or give advice. It can also be used to
express obligation as well as expectation.
Examples:
When you go to Berlin, you should visit the palaces in
Potsdam. RECOMMENDATION
You should focus more on your family and less on
work. ADVICE
I really should be in the office by 7:00 AM. OBLIGATION

26. Had Better
"Had better" is most commonly used to make
recommendations. It can also be used to express
desperate hope as well as warn people.
Examples:

today. RECOMMENDATION
That bus had better get here soon! DESPERATE HOPE
You had better watch the way you talk to me in the
future! WARNING
27. Ought To
"Ought to" is used to advise or make recommendations.
"Ought to" also expresses assumption or expectation as
well as strong probability, often with the idea that
something is deserved. "Ought not" (without "to") is used
to advise against doing something, although Americans
prefer the less formal forms "should not" or "had better
not."
Examples:
You ought to stop smoking. RECOMMENDATION
Jim ought to get the promotion. IT IS EXPECTED BECAUSE HE
DESERVES IT.
This stock ought to increase in value. PROBABILITY
Mark ought not drink so much. ADVICE AGAINST
SOMETHING (NOTICE THERE IS NO "TO")
28. Must
"Must" is most commonly used to express certainty. It can
also be used to express necessity or strong
recommendation although native speakers prefer the more
flexible form "have to." "Must not" can be used to prohibit
actions, but this sounds very severe.
Examples:
This must be the right address! CERTAINTY
Students must pass an entrance examination to study at
this school. NECESSITY
You must take some medicine for that cough. STRONG
RECOMMENDATION
Jenny, you must not play in the street! PROHIBITION
