What

We
have

three
of
them
for

check
out.

Iron
Man
suitHave
you
ever
dreamt
of
flying
like
Iron
Man?
This
suit
made
by
a
British
company
may
make
your
dream
come
true.
When
wearing
the
suit,
people
can
take
off
and
fly
just
like
Iron
Man.
With
the
help
of
five
mini
engines,
the
suit
can
reach
a
top
speed
of
80
km
per
hour,
nearly
as
fast
as
a
car.
The
suit
is
quite
expensive-sold
for
$
440,000
(about
3
million
yuan).

The

165
(about

1．细节理解题。根据“The
suit
is
quite
expensive-sold
for
$
440,000
(about
3
million
yuan).”可知，这套装相当昂贵——售价44万美元(约合人民币300万元)。故选D。

tracker
is
a
device
that
can
help
you
find

3．推理判断题。本文向我们介绍了三个发明，所以推测可以在杂志中看到这篇文章，故选D。
IV.书面表达
The
Most
Useful
Invention
Mobile
phones
are
one
of
the
most
useful
inventions.
It
was
invented
by
an
American
called
Martin
Cooper
in
1973.
I
should
say
that
mobile
phones
have
really
changed
our
lives.
First,
it's
more
convenient
to
communicate
with
others
by
using
mobile
phones.
Second,
people
are
used
to
taking
photos
with
mobile
phones
instead
of
cameras.
And
we
can
even
go
shopping,
listen
to
music
and
watch
movies
on
the
phone.
Third,
we
can
easily
learn
something
useful
by
surfing
online.
In
this
way,
it
helps
us
study.
In
my
opinion,
we
teenagers
should
be
allowed
to
use
mobile
phones,
but
not
on
weekdays.
And
it's
necessary
to
use
them
in
the
right
way
with
the
help
of
our
teachers
and
parents.
