一、考查其构成
"助动词have
(has)
+动词过去分词"构成现在完成时。如：

never
seen
Chinese
films，____
?
A.
hasn't
she
B.
has
she
C.
isn't
she
D.
is
she
析：陈述句部分含否定词never,简略问句部分要用肯定式，又因Kate's是Kate
has的缩写，故选B。
2.
His
uncle
has
already
posted
the
photos
to
him.
(改为否定句)
His
uncle
______
posted
the
photos
to
him
______.
析：already常用在肯定句中，yet常用在否定句、疑问句中，故填hasn't,
yet。
3.
-Ann
has
gone
to
Shanghai.
-So
______her
parents.
A.
has
B.
had
C.
did
D.
have
析："so+助/系/情态动词+主语"结构中的动词形式应与前句结构中动词形式保持一致，又后句的主语为her
parents是复数,故选D。
二、考查其用法与标志词
(一)当句中有never,
ever,
just,
already,
yet,
before等时，常用现在完成时。如：
1.
-Mum,
may
I

basketball?
　-______you______
your
homework
yet?
A.
Do;
finish
B.

2.

surfed
B.
Have;
surfed;
surfed
C.
Did;
surf;
have
surfed
D.
Have;
surfed;
have
surfed
析：据yet和before可知,应用现在完成时，故1题选D，2题选D。
(二)当句中有"for
+段时间"或"since
+点时间"等时，主句常用现在完成时，谓语动词必须是延续性动词，若是非延续性动词，要改为延续性动词或表状态的词(短语)。如：
1.
His
brother
has
been
to
Stone
Forest
twice______he
came
to
Yunnan.
　A.
after
B.
before
C.
since
D.
for
析：主句用的是现在完成时，而从句用的是一般过去时，故选C。
2.
Tom______the
CD
player
for
two
weeks.
　A.
has
lent
B.
has
borrowed
C.
has
bought
D.
has
had
析：A、B、C均为非延续性动词，在肯定句中不与表"段时间"的短语连用，故选D。
3.
I______a
letter
from
him
since
he
left.
　A.
didn't
receive
B.
haven't
got
C.
didn't
have
D.
haven't
heard
析：据since可知，应排除A、C，"hear
from
sb.=receive/get/have
a
letter
from
sb."意为"收到某人的来信"，故选B。
三、考查have/has
been
(to,
in)/have/has
gone
(to)的区别。如：
1.
-Have
you
ever______Lintong
to
see
the
Terra
Cotta
Warriors?　-Yes,
I
have.
　A.
went
to
B.
gone
to
C.
been
in
D.
been
to
析：据句中的have，排除A，B项意为"去某地了"，C项意为"一直呆在某地"，D项意为"去过某地"，符合题意，故选D。
2.
My
parents
______
Shandong
for
ten
years.
　A.
have
been
in
B.
have
been
to
C.
have
gone
to
D.
have
been
析：本题句中有"for+段时间"结构，据此可排除C，B项意为"去过某地"，不合题意，D项缺介词，故选A。
四、考查现在完成时与其他时态的联系和区别。如：
1.
Sun's
aunt
has
gone
there
for
ten
years.(改成正确的句子)
析：非延续性动词与"段时间"连用时，除了把非延续性动词改成延续性动词外，还可把动词改为一般过去时或借助句型"It's
+段时间+since+从句"进行句子转换。故答案为：Sun's
aunt
has
been
there
for
ten
years.
/Sun's
aunt
went
there
ten
years
ago.
/It's
ten
years
since
Sun's
aunt
went
there.
2.
Susan
has
been
in
this
city
for
more
than
ten
years.(改为同义句)
　________more
than
ten
years
____Susan
______to
this
city.
析：据上题分析，且since引导的从句要用一般过去时，故填It
is,
since,
came。
3.
I
won't
go
to
the
concert
because
I
____my
ticket.
　A.
lost
B.
don't
lose
C.
have
lost
D.
is
coming
析：因我丢了票的动作发生在过去，而且对现在造成了我不能参加音乐会的结果，符合现在完成时所表示的含意，故选C。
