用法没有任何不同,只是时态不同。had to 是一般过去时,have to 是一般现在时。

had to和have to都是“不得不”的意思,但是:had to是一般过去时态,比如:It was rainy, so I had to stay at home yesterday.昨天下雨了,所以我不得不呆在家。have to是一般现在时态,比如:You have to finish your homework before you watch TV.你必须先完成作业再看电视。

这里用have to wait是不得不等的意思,没有其他的办法
have had to wait,是过去完成时,因为是在问话人说话之前已经等了
如果不用had to,要说成How long have you waited?你已经等了多久?意思不太一样.

从语义上说,这两个表达方式都是表达说话人的判断.前一个的推断、猜想意味浓厚,因为年代久远的事,推断的把握不是很大,用would have had to更为合体;而后一句逻辑性很明显,自然就用would have to.要注意的是,这两个用法的“判断”含义都是在讲述过去事情的条件才有的.would have to 如果用在现在时中多是表示“建议”.

had to 的原型是 have to (意思是:必须做什么,不得不做什么)
have to 后面接动词原形,因此用water (在这里是动词,意思是:给......浇水)

B


Joe Jones是 八个孩子中最大的,他 16 岁时不得不从高中辍学去农场帮助父亲。 the eldest of the eight children 作Joe Jones的同位语;A.leave离开;后直接跟名词,不用接out of; C. fall 落下; D. go去;B. drop out of…表示“退出,离开……”,是固定短语,故选B。

请问下面英文的中文意思.
Margaret Meriweather,33,of San Francisco,had to cope with that problem.Her parents had gone through a messy divorce."I had some resentment," says Meriweather,who took Luskin's forgiveness class three years ago."I felt betrayed and abandoned by my father." For Meriweather,the most difficult part of the process was writing down her grievance story,because she had to extricate her own feelings from those of her family members.Yet she found it freeing to examine her expectations:"my father should have behaved better during the divorce","my father should not have lied to me.

应用had to,因为must是一个情态动词,没有过去时和三单形式,但 have to都 有.
例如,
She has to attend the meeting to listen to his report.这里的has to可直接换成 must.意思是她必须参加这个会议去听他的报告.[以后不懂的可以问我.]

Sudha Chandran, a well-known dancer from India, had to have
Sudha Chandran, a well-known dancer from India, had to have her right leg cut after a car accident. She was also on her career path.
Though the accident brought her bright career to a , she didn’t give up. In the months that followed, Sudha met a doctor who developed a man-made rubber filled with sponge (海绵). So she wanted to go back to dance after she had been fitted with her new leg. Sudha knew that she believed in herself and could realize her dream, so she began her courageous journey back to the world of dancing --- to walk, turn, jump, balance, bend, stretch, twist, twirl...

After every recital (music, dance given by one person) she would ask her dad about her performance. “You have a long way to go” was the answer she used to get in return. In January 1984, Sudha made a historic by giving a public recital in Bombay. She performed in such a great success that it moved everyone to tears and this pushed her to the highest position again. That evening when she asked her dad the question, he didn’t say anything. He just touched her feet as praise.
Sudha’s comeback was so moving that a film producer to make the story into a hit film.
When someone asked Sudha how she had managed to dance again, she said quite simply, “You don’t need feet to dance. is impossible in this world. If you have the will to win, you can achieve anything.” (266)

1.must表示主观意愿,意为"必须、应该".例如:
You must attend the class meeting.你应该出席这个班会.
He must return the story-book.他必须将这本故事书还回来.
2.以must引起的疑问句,否定回答通常用needn't或don't/doesn't have to,意为"不必".例如:
-Must I clean the classroom?我必须打扫教室吗?
-Yes,you must(No,you needn't/No,you don't have to).是的,你必须(不,不必了).
3.must的否定结构mustn't意为"禁止、不许",语气较为强烈.例如:
You mustn't go swimming today.你今天不许去游泳.
You mustn't drive so fast.不许开得这么快.
4.must可表示有把握的判断或推测,意为"一定、准是",一般用在肯定句中.例如:
He must be a middle school student.他一定是名中学生.
She must live in Beijing.她一定住在北京.
5.在"You must..."句中,它的意思与祈使句相同.例如:
You must come here early.=Come here early!早点来这儿!
You must hurry up!=Hurry up!你必须快点!
6.must与have to都有"必须、应该"的意思.但二者有区别:
1) must侧重于个人意志和主观上的必须,have to则侧重客观上的必须,可译为"不得不".must与have to经常可以互换使用.例如:
I must/have to go to school now.现在我必须上学了.
2) must可用来表示现在和将来的必须,无时态变化;have to则有更多的时态变化.例如:
He had to give up the plan.他不得不放弃这个计划.
I will have to buy a new pen.我不得不买枝新笔.
3)变否定句时,must只要直接在其后加not,而have to既可变成haven't to,也可变成don't have to/doesn't have to.
