一.现在完成时和一般过去时都是说过去的事情，但现在完成时注意的不是事情本身，而是强调事情与现在保持的某种密切联系（如现在的结果，影响,一直延续到现在等）;而一般过去时，则只讲述发生在过去的动作和事情与现在没有关系。
三、现在完成时和一般过去时用法比较
eg：He
has
bought
a
car
他已经买了一辆汽车。
He
bought
a
car.
他曾买过一辆汽车。
?
第一句用现在完成时时态，想表达意为：“He
bought
a
car.
And
he
still
has
it”
“过去他买了一辆汽车，现在他还有这辆汽车”
。
?第二句意为：“He
bought
a
car.
But
we
don't
know
if
he
still
has
it”
用过去时只叙述过去他买过一辆汽车这一事实，至于现在他是否有这辆汽车并未强调说明。
二、一般过去时与现在完成时时间的状语不同:
过去时时间状语：yesterday,
the
day
before
yesterday,just
now，
时间+
ago,
last
+时间
等;
We______alreddy_________(finish)our
task
last

eg:We__________(finish)our

现在完成时时间状语：already,

Have
you
ever
read
this
story？Long
long
ago，all
feelings
lived
on
an
island（岛）：Happiness，Sadness，Knowledge
and
all
of
the
others，
1
Love.One
day
it
was
said
that
the
island
would
sink，so
all
of
the
feelings
were
busy
making
boats
and
ready
to
go.
The
crucial
moment
came
at
last!
When
the
island
2
sank,
Love
gave
her
boat
to
poor
people
who
couldn't
make
a
boat.Now
it
was
Love's
turn
to
ask
for
help.
Richness（财富）was
passing
by
Love
in
a
boat.Love
said，“Richness，can
you
take
me
with
you？"Richness
3
，“No，I
can't.There
is
a
lot
of
treasure（金银财宝）in
my
boat.There
is
no
room
here
for
you."Just
at
that
time，Sadness
was
near，so
Love
asked，“Sadness，let
me
go
with
you."“Oh，Love，I
am
so
sad
that
I
need
to
be
alone
by
4
."Happiness
passed
by
Love，too，but
she
was
too
5
to
hear
clearly
what
Love
said
to
her.
Suddenly,
there
was
a
6
,"Come
on,
Love,I
will
take
you
with
me."It
was
an
elder.
Love
even
forgot
to
ask
him
where
they
were
going.
When
they
7
a
safe
place,
the
elder
went
away.
Love
asked
Knowledge,
another
elder,"Who
helped
me?"
"It
was
Time."Knowledge
answered.
"Time?"asked
Love."But
why
did
Time
help
me?"
Knowledge
smiled
8
answered,"Because
only
Time
can
understand
how
important
Love
is."
