چنانچه بعد از have و has از حرف اضافه to استفاده کنیم معنی must ( مجبوربودن ) را می دهد و می توان از
have got to , has got to نیز به جای آن استفاده کرد. مثال :
I must go now
I have to go now
I have got to go now
من باید حالا بروم.
he must go now
He has to go now
He has got to go now
او باید حالا برود.
have to, has to در زمان حال ساده
I have to get up early
جمله مثبت
I do not have to get up early
جمله منفی
?Do I have to get up early
سوالی
فعل had to در زمان گذشته
I had to get up early
جمله مثبت
I did not have to get up early
جمله منفی
?Did I have to get up early
سوالی
زمانی که did در جمله سوالی زمان گذشته به کار رود had to تبدیل به have to می شود.
he had to go to school.
did he have to go to school?
زمانی که does , do در جمله سوالی زمان حال ساده به کار روند فقط از have to استفاده می کنیم.
