Must အပုိင္း (၃)
===========

ေနာက္တစ္ခု သိထားရမွာက reported speech must ကေန Had to ေျပာင္းမွာလား မေျပာင္းရဘူးလားဆုိတာပဲ။

Quirk (A Comprehensive Grammar of the English Language, Longman, 1985) ဆုိတဲ့ နာမည္ၾကီး သဒၵါစာအုပ္ၾကီးႏွင့္ Collins COBUILD မွ စာမ်ားကုိ ေလ့လာမိေစရန္ တင္ေပးလုိက္ပါသည္။

(A) He told them again that they had to learn to love each other.

However, the alternative way to express this kind of sentence keeps the modal must in its present form:

(B)He told them again that they must learn to love each other.

In fact, Quirk (A Comprehensive Grammar of the English Language, Longman, 1985) states:
In its obligational sense... the past of must may be replaced (italics added) by had to in indirect speech:

His parents told him that he must/had to be in by ten that night.

So, this reliable reference tells us that both must and had to are properly used in this kind of sentence. In addition, we see authentic examples of both in current use in the Collins COBUILD .
Of the first 40 examples in each of the following searches, we found:

1) the reporting verb “said,” appears with “had to” in the dependent clause following it 25 times, as in these examples:

The survey said actors, models and musicians had to…

…Nick Partridge said that more had to be done to reach people…

2) the reporting verb “said” appears with the “must” of obligation following it 11 times, as in these examples:

Lord Mackay’s letter said that judges must act and must be allowed to continue…

We said that these two assumptions must be tested before any of the…

3) the reporting verb “told” appears with “had to” in the dependent clauses following it 30 times, as in these examples:

…teleconference panelists told callers that they had to help improve the…

…damage the blood vessel walls, and told her that she had to limit her intake…

4) the reporting verb “told” appears with the “must” of obligation following it 19 times, as in these examples:

…at Arlington Cemetery. There he told Americans that they must…

The letter told Morgan that he must clear all his…

Had to appears almost twice as frequently as must in these dependent clauses following the reporting verbs said and told. This suggests that had to is indeed more common than must in the dependent clause, as in the example question. However, must seems to be retained in more often when it represents a strong moral, ethical, or legal obligation, more than it is for an “every day” one.
