MUST, HAVE TO and BE TO compared

All these verbs have one mean­ing in common - obligation.But:

must shows obligation or necessity from the speaker's viewpoint.

§ I must do it. (I want to do it.)

§ Hemust do it himself. (I shan't help him.)

to have to expresses obligation or necessity due to circum­stances.

§ What a pity youhave to go now. (It's time for you to catch your train.)

§ Hehas to do it himself. (He has got no one to help him.)

to be to expresses obligation or necessity implying arrangement.

§ We are to wait for them at the entrance. (We have arranged to meet there)

In past tense the difference between three verbs is quite considerable. Must has no past tense and is not changed in the sequence of tenses.

§ He said hemust do it himself.

had to + infinitiveis generally used to denote an action which was realized in the past as a result of obligation or necessity due to circumstances:

§ Ihad to sell my car. (…because I needed money.)

§ Hehad to put on his raincoat. (It was raining hard outside...)

was (were) to + infinitiveshows planned action viewed from the past. The action was not realized in the past and the question remains open:

§ We were to meet him at the station. (Нам предстояло ...)

If the plan was not fulfilled - Perfect Infinitive is used:

§ Wewere to have met him at the station. (Нам предстояло, но ….)

had to + infinitiveis used in reported speech to express obligation.

§ He said hehad to make a telephone call at once.

In this case had to is close to must in meaning: it does not in­clude the idea of a realized action but refers to some future moment. Do not replacemustbyhad toin reported speech as they express different meanings.
