correct.


EAT--ATE

Don't confound the two. _Eat_ is present, _ate_ is past. "I _eat_ the
bread" means that I am continuing the eating; "I _ate_ the bread" means
that the act of eating is past. _Eaten_ is the perfect participle, but
often _eat_ is used instead, and as it has the same pronunciation (et) of
_ate_, care should be taken to distinguish the past tense, I _ate_ from
the perfect _I have eaten_ (_eat_).


SEQUENCE OF PERSON

Remember that the _first_ person takes precedence of the _second_ and the
_second_ takes precedence of the _third_. When Cardinal Wolsey said _Ego
et Rex_ (I and the King), he showed he was a good grammarian, but a bad
courtier.


AM COME--HAVE COME

"_I am come_" points to my being here, while "I have come" intimates that
I have just arrived. When the subject is not a person, the verb _to be_
should be used in preference to the verb _to have_; as, "The box is come"
instead of "The box has come."
