Need as a main verb has the question form do you need?, the negative you don’t need and the past forms needed, did you need? and didn’t need. It has two meanings: 1. to require something or to think that something is necessary: ▪ Do you need any help? ◇ ▪ I needed to get some sleep. 2. to have to or to be obliged to do sth: ▪ Will we need to show our passports?
Need as a modal verb has need for all forms of the present tense, need you? as the question form and need not (needn’t) as the negative. The past is need have, needn’t have. It is used to say that something is or is not necessary: ▪ Need I pay the whole amount now?

Grammar Point:
modal verbs
The modal verbs are can, could, may, might, must, ought to, shall, should, will and would. Dare, need, have to and used to also share some of the features of modal verbs.
Modal verbs have only one form. They have no -ing or -ed forms and do not add -s to the 3rd person singular form: ▪ He can speak three languages. ◇ ▪ She will try and visit tomorrow.
Modal verbs are followed by the infinitive of another verb without to. The exceptions are ought to and used to: ▪ You must find a job. ◇ ▪ You ought to stop smoking. ◇ ▪ I used to smoke but I gave up two years ago.
Questions are formed without do/does in the present, or did in the past: ▪ Can I invite Mary? ◇ ▪ Should I have invited Mary?
Negative sentences are formed with not or the short form -n’t and do not use do/does or did.
