Hayley教口語，“根本不是那么回事”用英語怎么說？

not a bit of it

said when a situation or event is very different from what you expected

根本不是那樣(指與預(yù)料完全不同)

I thought he would be sorry, but not a bit of it.

我原以為他會感到難過，但他根本沒當(dāng)回事。

I thought she would be glad to see him but not a bit of it — she made some excuse and left as soon as he got here.

我以為她見到他會很高興，根本不是那么回事!她找了個借口，等他一到就走了。
