have

yet
当表示动作已经完成并对现在有一定影响时，我们一般用现在完成时来表达。此时，可以分别用just，already或yet加以强调或说明。
如：
Present
perfect
with
already,
just
and
yet
1.
I
have
just
heard
the
news.
我刚听到消息。
2.
Astronauts
have
already
been
to
the
moon.
宇航员已经去过月球了。
3.
We
have
just
started
to
explore
other
planets.
我们才刚刚开始探索其他行星。
just
“刚刚”
两者都用于肯定句中
already
“已经”
一般置于have/has
之后,
V-ed
之前
4.
The
scientists
have
not
heard
from
it
yet.
科学家还没有收到它发出的信息。
5.
Man
has
not
discovered
any
life
in
space
yet.
人类尚未在太空中发现任何生命。
6.
Have
the
children
come
home
yet
孩子们已经回家了吗？
yet
用于
否定句:
“还未”、“以后可能会”
疑问句:
“已经”
置于句末
现在完成时表示该事件是在现在之前
的某一个时间里发生的，
重点在于强调已完成动作对
现在的影响
一般过去时表示在过去某一具体时
间发生的事情
I
have
just
been
to
London.
I
went
there
last
month.
我刚去过伦敦，上个月去的。
I
have
already
finished
my
homework.
I
finished
it
an
hour
ago.
我已经完成家庭作业了，一小时前完成的。
试比较：
当
A
问对方把自己的书放在何处时，他强调的是现在找不到了，故用现在完成时。但B的回答只是说明当时放的位置，故用一般过去时。
A:
Where
have
you
put
my
book
I
can’t
find
it.
B:
I
put
it
on
your
desk
yesterday.
当没有明确的过去时间状语时，判断该用现在完成时还是一般过去时的标准是：看该行为是否对现在有影响，即该句所强调的是什么。如：
A:
Would
you
like
to
go
and
see
the
film
with
me
tonight
你今晚想和我去看电影吗？
B:
Sorry,
I
have
seen
it
already.
不好意思，我已经看过那部电影了。
此时的现在完成时表示对结果的强调：“电影看过了，所以不想再看了”。
