3) must 与 have to 的区别 两者都表示“必须”,
a.强调重点不同must 侧重于说话者的主观看法,认为有必要或有义务去做某事;
have to 则重于客观需要,含有“不得不”或“被迫”之意:We must go at once. 我
必须马上就走。If I buy that car, I have to borrow some money. 如果我…, 我得借些钱。 b. 时态形式不同
must 只有现在时一种形式(在宾语从句中可以表示过去),而 have to 则有多种时态形式:She said (that) she must go with me. 她说她一定要同我一起去。
They have had to buy a car. 他们不得不买了辆小汽车。
c. 否定式的意义不同 must 的否定式 mustn’t 意为“一定不要”、“不允许”;
而 have to 的否定式 don’t have to 意为“不必”(=needn’t)。比较:
You mustn’t tell him about it.你一定不要告诉他这件事。(可能是秘密)
You don’t have to tell him about it.你不需要告诉他这件事。(他可能知道了)
