chooseing correct verb (noun) to use. He OUGHT to go to the dentist because he has toothache. --------------------------- Why not >> He HAVE to go to the dentist because he has toothache? I have one test book and there written that "ought" is correct but i think - "have" is ok too.Also couple of sentences: --------------------------- She WAS WAITING at the bus-stop when a young man took her bag and ran away. ------------- Why not >> She HAS BEEN WAITING at the bus-stop when a young man took her bag and ran away?

Ought to: should do something, but s/he doesn't do that. Have to: have to do something, without any other choice. Maybe s/he will do that. You could say the difference. He has a toothache and he ought to go to the dentist, indicating that he didn't go there. BTW, Choosing, instead of chooseing; Has to, not have to, following "he" :)

for the 2nd part: we use 'has been' for an action that is still happening (not finished), but as you see the act of waiting has finished and she's not waiting anymore.

1. ought to = suggestion have to = necessity Just two different meanings. 2. Because it is correct and the other one is just plain wrong. You will have to learn this stuff.

Хмм, но все же почему не "have" а именно "ought" ведь они оба там уместны. Не так ли? Спасибо за пояснения перфекные времена мне пока что даются с трудом. Ни как не могу натренироваться на них.

Привет! Достаточно часто смыловое значение ought близко к "желательно"(не всегда) или выражает сильную возможность предполагаемого действия.Пример с автобусной остановкой - "чистый" Past Continuous (действие шло вместе со временем).Перфектная форма требует либо связи действий с настоящим,либо результативности в настоящем.Грамматические упражнения не предполагают творчества, желательно строго следовать моделям и правилам.Удачи!
