Student or Learner
you better use computer to work this.
what,s the meaning of you here?is it the better for me or for anybody??
i confused,why i dont say i was better??
*** NOT A TEACHER ***
(1) I think that the "correct" sentence is:
You had better use a computer.
(a) It is true that many native speakers drop the "had," but
since you are a "learner," I most respectfully suggest that
you always say (and especially write) "had better."
(b) "Had better" can be very strong. Almost like a threat:
You are standing in the way. You (had) better move!!! Or I shall ....
(i) I most respectfully suggest that you not use this modal
until you really understand English. The words "should"
and "ought to" are more "gentle":
You should/ought to use a computer.
Thank you & have a nice day
P.S. In your sentence, "had better" is NOT a threat. Nevertheless,
since you are a "learner," you might ACCIDENTLY use it in a sentence
that sounds like a threat.
