题目内容
I________look after my little brother at home that day because Mother was out．
- A.have to
- B.must
- C.had to
- D.needn't
分析：句意是“因为妈妈出去了，我那天得在家里照顾小弟弟。”，表示的概念是“必要性”，D项needn't是“不必要”，不符合句意。have to，must，had to都可以表示“必要性”，由于本句是指过去的事情，所以不能用have to(一般现在时)，must．(没有过去式)，要用C项的had to(是have to的过去式)。(延伸)have to和must都表示“必要性”，但两者是有区别的。1)must只有一个时态，用于表示现在的必要性，但也可以用来表示将来的必要性，如：We must study hard．(指现在)You must come here tomorrow．(指将来)但是have to有多种时态(常用一般现在时、一般过去时、一般将来时)，如：You will have to come tomorrow．(注意避免说成You have to come here tomorrow．)因此在表示过去的必要性时，一般要用had to，不用must(但在间接引语中仍然可以用must)．2)否定结构时属于不同的概念，mustn't表示的是“不许可”“不允许”的意思，而don't have to的否定形式表示的是“不必要”。3)must有别的用法(表示“可能性”的非常肯定的推测)，而have to只能表示“必要性”。4)表示“必要性”时，用must表示的是说话人的主观看法，而have to表示的是客观需要，如：I have to leave now．You must come here tomorrow．
