have to什么意思、怎么读?单词用法、记忆法、发音音标、反义词辨析、词语翻译、例句造句

have to 音标:[hæv tu:]

modalv.不得不;必须
  • must 和 have to的用法区别

    1. must 侧重于个人意志和主观上的必要。have to 侧重于客观上的必要,可用于现在时、过去时和将来时。例如:
    I know I must study hard. 我知道我必须努力学习。
    My brother was very ill, so I had to call the doctor in the mid-night.
    我弟弟病得厉害, 我只得半夜里把医生请来。
    I haven't got any money with me, so I'll have to borrow some from my friend.
    我身上没带钱,只好向朋友借点了。
    He said they must work hard.他说他们必须努力工作。

    2. have to可以用于多种时态;而must只用于一般现在或将来。例如:
    The composition is due to hand in this morning, so I had to finish it last night.
    作文今天早晨到期,因此我不得不昨天晚上完成。
must/have to

I must do my best.我必须尽我所能去做。
Mother is ill,I have to look after her at home.母亲病了,我必须在家照顾她。
<辨析>两者都可以表示“必须”。must 着重于主观上以为有义务,有必要。have to 着重于客观上的需要,含有“不得不”的意味。如:
We must work hard.我们必须努力工作(是我们要这样做)
We have to work hard.我们得卖力干活。(环境使我们不得不这样做)
must 只有一种形式,通常表现在或将来时间,而 have to 有各种时态形式。如:
When I was your age,I already had to work.我象你们那么大时,早已不得不工作了。
I'll have to go with her tomorrow.明天我得同她一道去。
注意:用于否定,两者意思有很大的不同。mustn't 表示“不准”,“不许可”,“禁止”;have not to(或 don't have to)表示“”不必,与 needn't 同义。如:
You must not smoke in the classroom.不准你在教室里抽烟。
You don't have to worry about his studies.你不必为他的学习而担心。
