Unit 1 Our Earth
Listening
Audio
Track 4-1-1
1.
I’ve
visited
a
few
caves
in
Guilin.
The
rocks
in
the
caves
are
in
different
shapes
and
colors.
If
you
use
your
imagination,
the
rocks
can
resemble
many
different
things.
It looks like a whole other
world.
2. I went to the
desert in Gansu once. As I stood in the middle of
the desert, I
faced
endless
sand
and
felt
very
small.
By
day
the
desert
was
extremely
hot,
by
night
it got very cold. I experienced summer
and winter in the same day.
3. To my knowledge, California has
beautiful coastlines. People love them and
thousands of volunteers often give up
part of their weekends to keep the sandy
Californian beaches clean.
4. The Port of Shanghai is located at
the mouth of the Yangtze River. It handles
many
millions
of
shipping
containers
each
year.
In
fact
it
might
even
be
the
busiest
container port in
the world.
5. Japan has many
hot springs. Some of them are located in
mountainous areas and
are
great
attractions
to
foreign
tourists.
Supposedly,
the
hot
springs
have
healing
properties.
6.
The most famous mountain range in the world is the
Himalayas. It contains the
world’s
highest mountain, Mount Everest . Qomolangma),
which climbs to a height
of 8,848
meters.
7.
The
White
Cliffs
of
Dover
are
one
of
the
United
Kingdom’
s
most
spectacular
natural
sights.
The
cliffs
are
made
from
bright
white
stone.
On
a
clear
day,
they
are
visible
from
France, approximately 30 kilometers
away.
8.
Mount
Vesuvius
is
a
famous
volcano
in
Italy,
which
has
not
been
active
for
about
two
centuries. But people say it might erupt again,
someday soon.
9.
Niagara
Falls
crosses
the
border
of
two
countries,
Canada
and
the
United
States.

Every
year,
millions
of
tourists
observe
the
beauty
of
these
magnificent
waterfalls.
More
recently,
the
waterfalls
have
become
a
valuable
source
of
hydroelectric
power.

Blake: What are you working on,
Mary
Mary: I’m finishing my
paper. It’s due tomorrow, Blake.
Blake: What’s the topic
Mary: It’s about Greenland.
Blake: Greenland. Hmmm …
that’s part of Canada, right
Mary: I think you need to study your
world geography, Blake.
Blake: Well, isn’t it near
Canada
Mary: Yes, it’s off
the coast of northeast Canada, but it’s part of
Denmark.
Blake: Oh, I didn’t
know that. Well, what’s your paper
about exactly
Mary:
In
my
paper,
I
answer
the
question
“Is
Greenland
really
green”
In
other
words,
is Greenland covered
by a lot of plants and trees
Blake: Is it
Mary: What do you think
Blake:
Let’s
see
…
Greenland
is
in
the
Arctic
Circle
—
way
up
north.
It’s
cold,
…
so “Is Greenland really green” I’d
answer “probably not.”
Mary:
You’d be correct. It’s too cold there. In the
north, a lot of the ground
is frozen.
The summers are short, so only the surface
thaws.
Blake: That sounds
tough.
Mary:
It’s
hard
for
the
construction
industry.
It’s
not
easy
to
build
in
Greenland.
Blake:
It sounds so harsh. Why would anyone want to go
there
Mary: There are big
mountain ranges on the coasts. They’re great for
hiking and
outdoor sports. And there
are lots of animals there. You can sometimes see
whales
swimming in the
harbors.
Blake: That sounds
cool! OK, so if it’s not really a “green” place,
why was it

named “Greenland”
Mary:
The
first
settlers
wanted
to
attract
other
people.
They
gave
it
an
attractive
name.

Jay:
Come in here, Elise. You should see this
show!
Elise: What is
it
Jay: It’s called “The
Titanic of the Sky.” It’s about the Hindenburg, a
great
engineering feat.
Elise: The Hindenburg …
Jay: You know, that giant zeppelin that
crashed in 1934. Thirty-five people
died.
Elise: Oh yeah, I
remember now. It was flying from Germany to the
United States.
It crashed as it was
landing.
Jay:
Right.
It’s
so
funny
looking,
don’t
you
think
It
doesn’t
look
anything
like
the
airplanes we have today.
Elise:
That’s
true.
Why
would
people
ride
in
a
zeppelin
anyway
It
seems
so
dangerous.
Jay:
Well, some people called the Hindenburg “man’s
greatest achievement in
flight.” They
thought it was safe, I guess.
Elise: Who rode in it anyway
Jay:
Mostly
wealthy
people.
It
accommodated
between
30
and
40
passengers
and
crew.
One person said it was
like a “flying hotel.”
Elise: It sounds pretty
great.
Jay:
Yeah,
and
it
was
fast.
That’s
why
people
rode
it.
They
wanted
to
get
to
their
destination faster.
Elise: Wh
y didn’t they just
take a jet plane
Jay: Elise!
You know they didn’t have jets back then. Look, in
1934 it took five
days
to
travel
from
Germany
to
the
US
by
ship.
The
zeppelin
could
do
it
in
half
that
time. It was speedy.

Elise:
Well,
maybe
I’ll

little
bit.
Maybe
I’ll

something …

Jack: I think we
should buy a bigger car. Big cars are
safer.
Kayla: Yes, but on
the other hand, they consume more oil.
Jack: They also look really
cool.
Kayla: That’s true,
but there are some SUVs which are not that big but
also very
beautiful.
Jack: And I think big cars are more fun
to drive.
Kayla: But then
again, it’s very expensive.
Jack: Well, let’s get more information
about several kinds of car

okay

My
country
has
two
very
famous
buildings
called
the
Petronas
Towers.
The
buildings
are
made
of
glass,
steel,
and
concrete.
They
were
designed
by
an
American
architect,
but
he
used
a
Malaysian
style.
They
were
finished
in
1998,
and
they
were
the
tallest
buildings in the world at that time.
Each tower has 88 floors, and is 452 meters
high.
I
really
like
the
Petronas
Towers.
They
show
both
the
modern
and
the
traditional
side of my
country.
Audio Track
4-1-10/Audio Track 4-1-11
Modern buildings: We love them, we hate
them.
The
world-
famous
Louvre
Museum
in
Paris
is
almost
500
years
old,
and
it
faced
a
very
modern
problem:
There
simply
wasn’t
enough
space
for
six
million
visitors
each
year.
In
1989,
American
architect .
Pei
designed
a
striking
glass
pyramid
in
the
building’s center to be a visitor’s
entrance and shopping arcade. But he also
started an angry debate. Some people
felt his glass building was a piece of art,
like the ones inside the museum. Others
said it was just an ugly, modern
mistake.
Kyoto,
Japan, is
the country’s
ancient
capital, and the heart of
its culture. Its

railroad station was too small for the
millions of visitors. In 1997, the city
completed a new station in a huge
shopping center, right in the oldest part of the
city. Designed by Hiroshi Hara, the
building also contains a hotel and department
store.
Before
it
was
built,
critics
said
that
the
high,
wide,
modern
building
would
destroy the city’s
traditional look. On the other hand, supporters
said it would
bring new life into the
city center.

4-1-12/Audio Track 4-1-13
Interviewer: What do you think is the
biggest problem facing our cities
Erika: I think it’s overcrowding. Talk
to anyone living in a major metropolitan
area
and
they
will
say
the
same
thing
.
There’s
no
space.
Even
the
suburbs
are
getting
crowded.
Interviewer: Well, in some places there
simply isn’t any land left for building,
right
Erika: Yes,
that’s true, but you have to think creatively. You
can’t give up so
easily.
Interviewer: Think creatively What do
you suggest
Erika: What I’m
saying is that we can build more structures
underground. We can
add parking lots,
malls, hotels and even apartment buildings.
There’s plenty of
space.
Interviewer: Isn’t it
expensive
Erika: Yes, it can
be. In the past building underground has been very
expensive.
However, we have new
technology that will bring the cost down. It
involves using
robots. You don’t have
to pay robots a salary.
Interviewer:
Isn’t
“building
down”
more
dangerous
than
other
kinds
of
construction
Erika:
Actually,
I
think
it’s
safer
than
building
skyscrapers,
for
example.
Remember, we already do it. We have
subways, and underground shopping malls. I’m

just suggesting we invest in a variety
of bigger projects and that we dig
deeper.
Interviewer: What
would you say to people who doubt your
idea
Erika:
I can
understand
their feelings.
Whenever there’s a
new idea,
it can cause
controversy.
But “building down” is not some kind of
impractical idea. It makes
sense. There
is so much space underground: it can accommodate a
lot of traffic,
storage,
and
people.
With
the
new
technology
we
have,
we’d
be
crazy
not
to
consider
the idea
—
it’s the wave
of the future.

Bart: So what exactly did you do over
the summer
Gustav: We worked
as volunteers at Glacier National Park.
Bart
: I’ve never been there.
What’s it like
Carolina:
It’s
beautiful.
There

and,
of
course,

Bart: How was the job
Gustav: We had to do a lot of physical

Carolina: That’s true, but it was
