I hear that "You had better--" sometimes connotes a warning or (in some cases) a threat,
therefore Non-native speakers should be careful
about using this phrase to avoid any misundersdanding.
On the other hand, this phrase can very often
be heard in everyday life like the examples below.
1.You look pale. You had better go see a doctor.
2.You'd better come back soon. The party has already begun.
3.Hey. you'd better watch this TV show. It's
So, could you tell me in what cases "had better"
could be taken as a warning or threat, and what
cases it is not?
