2. He must not go. He was not to go. He must not go.
-
3. He need not go. He need not have gone. He need not go.
OUGHT to & USED to
-
Ought to – should
-
Ought is always followed by to.
-
Ought to (like Should) is used to denote –
-
Moral Duty - You ought to respect your elders.
-
You ought to have helped the poor.
-
Probability - Mohan ought to win the race this time.
-
You have worked hard. You ought to get good marks.
-
Something Desirable - He ought to build a new house now.
-

-
In all the sentences given above, ‘should’ can be used in place of ‘ought to’.
‘Used’ is modal auxiliary which (like ‘ought’) is always followed by ‘to’.
RULE If verb comes after used to then
-
when he was in London
-
5 He is used to telling lies and it has
-
become his second habbit.
-
it is followed by v1+ing and it denotes
-
here a routine action of past and it can
-
be in any tense here.
NEED
‘Need’ is used :
As an auxiliary, ‘Need’ should be used only in Negative and Interrogative sentences.
-
‘Need not’ (needn’t) is used to express the absence of obligation or necessity to do something
-
In interrogative sentences ‘need’ is used to indicate some doubt or prohibition.
-
Need you go yet? No, you needn’t.
-
Need she come tomorrow? No, she needn’t.
-
The Third Person Singular of ‘need’ is always need, and not needs.
-
He need not worry any more.
-
In interrogative sentences ‘need’ is used only if a negative answer is desired.
-
Need you go there?
-
No, I needn’t.
-
In negative and interrogative sentences ‘need’ is never followed by ‘to’.
-
Need he do any work?
-
No, he needn’t do any work.
-
But in the following simple sentences ‘need’ is followed by ‘to’
-
1. He need to go now.
-
2. He does not need to go now.
-
3. Does he need to go now?
-
If you study the given sentences carefully, you will find that here ‘need’ has been used as a
-
Principal verb and not as an auxiliary.
-
. We can use hasn’t +v3+ go to, don’t have to, don’t need to in place of ‘need not’.
-
He need not go.
-
He has not got to go.
-
He does not have to go.
-
He does not need to go.
-
When ‘need’ is preceded by ‘must’, it becomes an Adverb.
-
In fact, ‘needs’ is a Possessive Case in which the apostrophe (‘) is omitted. Thus – needs = need’s
-
= of need = of necessity = necessarily (adv.)
-
Now we see how ‘needs’ has come to be considered an Adverb.
DARE
As an auxiliary ‘Dare’ is used in the following cases:
-
1. In Negative sentences.
-
2. In Interrogative sentences.
-
3. In sentences expressing some doubt.
-
4. In sentences with hardly, never, no one, nobody.
-
‘Dare’ is not followed by ‘to’ when it is used as an auxiliary.
-
The Third Person Singular of ‘dare’ is always ‘dare’, and not ‘dares’.
-
Examples:
-
He dare not fight with me (Negative)
-
Nobody dared ask him about his intentions (Negative)
-
He will hardly dare go there again (Negative)
-
