33.our
earth
will
be_____if
we
go
on
cutting
down
millions
of
trees
every
year.
A.in
great
danger
B.danger
C.dangerously
D.out
of
danger
选A.
(in
danger处于危险中,out
of
danger脱离危险,danger危险<名词>,
dangerously<副词>,此句中从句意和结构看应用in
great
danger.)
41.look
at
my
pen!
it's
the
same_______.
A.with
yours
B.as
yours
C.with
your
D.as
yours
选B/D.(
两选项怎么相同?the
same
as和...一样,
而且比较的是my
pen,所以用名词性物主代词.)
47.could
you
tell
me__________?
A.how
often
you
will
publish
the
newspaper
B.how
soon
they
would
publish
the
newspaper
C.how
often
will
they
publish
the
newspaper
D.how
soon
would
they
publish
the
newspaper
选A.
(B选项的时态不对,C/D的从句词序不对,A说的是他们将多久出一期报纸.)
48.she
was
so
frightened
that
she_______knew
what
to
say.
A.hardly
B.nearly
C.almost
D.clearly
选A.
(
hardly几乎不,有否定含义.整句是说她害怕得都不知道该说什么了.
其它选项不表达这个意思.)
51.the
teacher
told
us_______out
of
the
window.
A.look
B.not
look
C.don't
look
D.not
to
look
选D.
(
不定式to
do
sth.
的否定形式在其前面加not,所以是tell
sb.
not
to
do
sth.
)
