Tips:
some
day
和
the
other

的区别：
some
day指将来“总有一天、有朝一日、终将、(日后)某一天”，句子用一般将来时。如:
Your
wishes
will
come
true
some
day.
总有一天你的愿望会实现的。
Some
day
you’ll
have
to
pay
for
what
you
have
done.
总有一天你要为你的行为而付出代价的。
the
other
day
相当于a
few
days
ago,
意为“几天前、某天、那天、不久前”，句子用一般过去时。如：
I
met
her
in
the
street
the
other
day.
几天前我在街上碰见过她。
I
bought
the
watch
the
other
day.
这手表我是几天前买的。
1)
一般过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作；现在完成时强调过去的事情对现在的影响，强调的是影响。
Summary
2)
一般过去时常与具体的时间状语连用，而现在完成时通常与模糊的时间状语连用，或无时间状语。
一般过去时的时间状语：yesterday,
last
week,
…
ago,
in
1980,
in
October,
just
now等，皆为具体的时间状语。
现在完成时的时间状语：for,
since,
so
far,
ever,
never,
just,
yet,
till/until,
up
to
now,
in
past
years等，皆不确定的时间状语。
共同的时间状语：this
morning,
tonight,
this
April,
now,
already,
recently,
lately
等。
3)
现在完成时可表示持续到现在的动作或状态，动词一般是延续性的，如：live,
teach,
learn,
work,
study,
know。
一般过去时常用的非持续性动词（短语）有come,
go,
leave,
start,
die,
finish,
become,
get
married等。
句子中如有yesterday,
last
week,
in
1960时，不能使用现在完成时，要用过去时。

Tips:
some
day
和
the
other
day
的区别：
①
some
day指将来“总有一天，有朝一日，终将，（日后）某一天”，句子用一般将来时。如:
Your
wishes
will
come
true
some
day.
总有一天你的愿望会实现的。
Some
day
you’ll
have
to
pay
for
what
you
have
done.
总有一天你要为你所做的事付出代价。
②
the
other
day
相当于a
few
days
ago，意为“几天前，某天，那天，不久前”，句子用一般过去时。如：
I
met
her
in
the
street
the
other
day.
几天前我在街上碰见过她。
I
bought
the
watch
the
other
day.
这手表是我几天前买的。
Step
5 Summary
(1)
一般过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作；现在完成时表示过去的事情对现在的影响，强调的是影响。
(2)
一般过去时常与具体的时间状语连用，而现在完成时通常与模糊的时间状语连用，或无时间状语。
一般过去时的时间状语：yesterday,
last
week，…ago,
in
1980，in
October,
just
now等。
现在完成时的时间状语：for,
since,
so
far,

lately等。
(3)
现在完成时可表示持续到现在的动作或状态，动词一般是延续性的，如：live,

work,
study,
know等。
一般过去时常用非延续性动词（短语），如come,
go,
leave,
start,
die,
finish,
become,
get
married等。
句子中如有yesterday,
last
week,
in
1960等时，不能使用现在完成时，要用过去时。
