Have you finished planning your
presentation on building roads for
next Friday?
Yes, on Monday Michael and Ellie will
be finding out information about
two new roads in India and Japan
online.
In the library?
No, they won’t be using the library
much. They’ll be working at home
after school.
OK. That seems like a good start.
So what do you plan to do next?
Remember that a good presentation
has good pictures.
Well, on Tuesday, Tarik will be looking
for some good photos of the roads.
And on Wednesday, we’ll have all the
information, so we’ll be choosing the
best road to talk about.
Have you decided who will be
writing the presentation?
Yes, Kamil and Ana will be writing
notes for everybody. They won’t
be writing full sentences though.
We want the presentation to sound

more natural.
Good idea. And when will everything
be ready?
We’ll be finishing the slides on Friday
morning, ready for the presentation
in the afternoon.

Have you worked out yet how you’re
going to review for the tests at the
end of the year?
Yes, I’ve got a plan. I’ll be learning
some English grammar on Saturday,
and then on Sunday, I’ll be
reviewing the vocabulary lists at the
back of the book. What will you be
doing this weekend?
My weakest subject is music, so I’ll be
copying the words of all the songs
we’ve learned.
Why will you be writing them all!?
I can learn them better like that.
When will you be reviewing for the
history test?
Probably on Wednesday or Thursday.
I’ll be reading about the Pyramids
first.
That’s a good idea. I think there’ll
be a question on that. Will you
be looking at the chapter on the
Romans, as well?

No, I won’t be doing that. There
won’t be a question on the Romans

In our presentation today we will
be talking about a new road from
Calcutta in India to Ho Chi Minh City
in Vietnam.
Look at this old road in India. It’s
very crowded. For several years, the
engineers have been working on the
first part of a new highway to replace
it. They have been building a section
of highway which is hundreds of
kilometers long.
All last year, they were building the

section to Manipur.
Work is progressing very well at
the moment, and lots of drivers are
already using the two sections that
are finished.
Engineers are currently drawing up
plans for the section of the highway
that will cross Burma.
They think that work will be starting
in Burma in a few years. Does anyone
have any questions?
Yes, when will they be working on
the road to Vietnam?
They probably won’t be starting
work on that for several years.

My parents had decided that they
wanted to go somewhere warm for
the new year. We’d looked at lots of
places on the Internet and had finally
chosen a two-week vacation in Asia.
I’d wanted to stay in a house on the
beach, but my parents had booked
a hotel on a hill. The night before
the disaster, we’d gone for a walk on
the beach and had eaten in a little
restaurant facing the sea. Then we’d
gone to bed early. In the morning
we’d gotten up quite late. We
heard people shouting: “Tsunami!
Tsunami!” I’d never heard the word

“tsunami” before, and I had no idea
what it was. Later, I found out that it
was an enormous wave caused by an
underwater volcano or earthquake.
It had destroyed the buildings on
the seafront, including the little
restaurant where we’d had dinner
the night before. We felt so lucky to
be alive!

Oh, it’s quite old now. I bought it in
Asia just before the tsunami. We had
booked a boat trip the day before,
and we had visited a floating village.
We had been to the market there,
and I had bought it as a present
for myself. We had seen the village
school there, as well, and we had
had a nice meal in a little wooden
restaurant. It was a great day.
A floating village?
Yes, it was just made of wood and
was about a meter above the sea. I

had destroyed it.

statues. They had been working
hard all morning, listening to their

Jack looked at his watch. The guide
had been talking for twenty minutes
about African, Japanese, and Italian
masks. Jack carefully leaned back

Please look to the left, everyone.

Here is the famous aqueduct which
was built by the Romans. Welcome
to the Pont du Gard!
Aqueducts are big waterways that
carried water to towns. When an
aqueduct crossed a river, the Romans
built bridges. Look at this! This is the
place where they started to build
this bridge two thousand years ago.
It’s called the River Gardon. The
bridge has a beautiful design, with
symmetrical arches. Can you see
the Roman numbers on the stones?
This is the method that helped the
workers put the stones in the right
order. On the first level are six arches
that are supported by pillars. The
pillars have a diamond shape that
cuts into the water in the river. There
is a second level with eleven arches
and a top level where the water
flowed.
The Romans didn’t have big
machines. The workers made
supports from the trees which they
cut down. They built the bridge by
hand. It’s incredible!

Do you know a city in India called
Agra? This is the place where you can

The Taj Mahal is a building which is
famous around the world. It’s one
of the wonders of the world with its
beautiful symmetrical design.
Emperor Shah Jahan is the person
who built the Taj Mahal. He did it to
remember his queen, Mumtaz. She
was the woman who Shah Jahan
loved. She had fourteen children.
The Taj Mahal is a building that
took twenty years to build. They
finished building it in 1653. It’s
now the famous tourist attraction
that millions of people visit every
year. The most famous part of the
building is the tomb of Mumtaz. The

Do you know what this is? It’s a

person whose toy it was… I don’t

My mom let me borrow the toy to
show you.

Sir David Brewster invented it in
1816. He was a Scottish scientist
whose main interest was light.
One day he realized that you could
make beautiful patterns using
light and mirrors. He called it a
kaleidoscope.
In the 1890s, an American called
Charles Bush changed the design,
and it became a very successful
toy. So Bush is the man whose toy
became popular with Victorian
families. He was the person whose
toy was sold to hundreds of
thousands of children.
Thank you Dr. Brewster and Mr. Bush
for such an awesome toy!

and make the folds very neatly.
I taught Alex, Jack, Imani, and Hana

plane.
I helped someone whose plane is
square and flat. Here it goes!
And I helped this person whose
plane is fast and dangerous! Watch

How did the Ancient Egyptians
write?
The ancient Egyptians wrote using
picture words called hieroglyphs.
This style of writing, which was very
beautiful, didn’t include vowels
(AEIOU), or punctuation.
What was it like?
The writing, which could be read
in any direction, used thousands
of picture words or symbols. These
represented different objects, ideas,
and actions.
What did the Ancient Egyptians write
on?
On papyrus. Papyrus, which is a

water plant, was used to make paper.
They also carved symbols into stone,
and painted hieroglyphs on the walls
in tombs.
How can we understand them?
Because of the Rosetta Stone. ElRashid (Rosetta), where the stone
was found, is a town in the north of
Egypt. Some French soldiers, who
were building a fort, found the stone
in 1799.
The Rosetta Stone, which was made
over 2,000 years ago, has three
different types of writing on it. The
writing is in hieroglyphs, Ancient
Egyptian and Ancient Greek. It
has shown people how to read
hieroglyphs.

When did they start to use
hieroglyphs?
The Ancient Egyptians, who lived
along the River Nile in Egypt, started
to develop their writing system 5,000
years ago.
How can I read the signs?
The symbols, which were objects,
animals and people, were written
across the page or from top to
bottom. If the animal, bird, or person
is facing left, which looks like this,
you read from left to right.
If they face right, which looks like
this, you read from right to left.
Which direction do you read in your
language?
How did they learn to write using
hieroglyphs? Was it easy?
Scribe school, where students learned
to read and write, was hard work.
There were lots of symbols to learn.
Where did they use their writing?
When they finished, they used
writing in many different places. The
scribes, who learned how to read
and write using hieroglyphs, used
their writing to count animals, to
decorate temples and tombs, or to

send messages in war. Sometimes
they worked in government.
Can I try writing like an Ancient
Egyptian?
Yes, you can! Try to find the symbols
of the written language, which didn’t
have any vowels (AEIOU), and then
try to write your name.

My name is Fabien. I’ve been deaf
all my life, which means I can’t hear
at all, and I use sign language to
communicate.
I want to tell you about my favorite
school club. I belong to the “Hands
Up!” choir. It’s a sign language music
group, and it’s fantastic. It was
started by one of our teachers three
years ago. The club was held in a
classroom, but it became so popular
that we were told to move to the

larger school auditorium.
Sign language isn’t used by many
students at my school, but we are
taught it in the choir. When the
music is played, some people sing,
and others are silent, but we all use
sign language to tell the story of the
song.
We’ve entered local competitions,
and our club has been used as
a model for other schools. Local
schoolchildren have been invited to
come and watch us perform. That’s
my favorite part!

Can you tell us about sign language?
Sign language, which deaf people
use to communicate using their

hands and faces, is a language like
any other. Deaf children, who can’t
hear what their own voice sounds
like, can learn to lip read, speak, and/
or use sign language.
Is sign language a real language?
Yes! Sign language, which is used
by millions of people, is used to tell
jokes, make poetry, chat with friends,
and do all of the other things you
can do in your language. It even has
its own grammar and punctuation.
In my friend’s school, where there
are lots of deaf children, there is a
sign language club, and you can
take lessons to learn it. At my school,
which only has a few deaf children,
we even have a sign language choir!

C
1 Sign language, which is different
in each country, is not an
international language.
2 Sign language, which is widely
used today, was first used in the
1700s in Paris.
3 In Paris, where the first school
for the deaf was started, sign
language schools became famous.

Burglary at country house.
The burglary had happened during
the night. The gardener reported
that a hole had been cut in the fence
and some branches of a tree had
been broken. Maybe the hole had
been used by the burglar to get into
the garden.
The window of the living room had
also been opened. The only thing
that had been stolen was a painting.
It had been removed from the wall.
The painting had then probably
been wrapped in a curtain because a
curtain had been taken, as well. The
burglar alarm had not been activated

because it had been disconnected.
I think it could be an “inside job.” I
have another interview with the
gardener today.

Next year, we’re filming Emperor
penguins in Antarctica. In the winter,
it’s –50°C, and the penguins leave in
the summer, so it isn’t easy.
When will they be filmed?
They’ll be filmed in March when they
leave the sea, and walk home in a
long line. The eggs come in May, but
they won’t be looked after by the
females. They will be kept safe and
warm on the males’ feet—for two
months!
When will the eggs be hatched?
They’ll all be hatched by the end
of July. That’s a good time to take

photos.
Do the chicks hunt for food?
No, the chicks will be fed by both
parents.
What happens next?
Well, the chicks won’t be taught how
to swim. They’ll be left to learn how
to swim and hunt on their own. In
December, it’s summertime. There’s
lots of food. The penguins stay at sea,
and they won’t be seen again on the
ice until March of next year.

In most countries in Europe, white
storks aren’t hunted. They are loved
by everybody. However, when they
migrate and fly over Malta, many of
them are shot. Last year over twenty
birds were killed by people who did
it as a sport.

What is the longest distance that a
stork has migrated?
Before we had satellite tracking,
nobody knew for certain the
distance that had been flown by a
stork during migration. Now, many

migrations have been tracked from
Europe to West Africa.
Will storks still be found in Africa

In this film, a bird was chased by
a coyote, but the super-fast bird
always escaped. I only just found
out that road runners are real birds
and are found in North and South
America. Next year, a new cartoon
will be made in which the main
character will be a friendly dinosaur.

Monday
Today was a really bad day. I woke up
late and I ran to school. I was scared
my teacher would be angry.
I forgot that we had a math test. It
was difficult. I’m worried about the
results.

I left my lunch at home, so I didn’t
have anything to eat. Then it started
raining on the way home. I had
forgotten my coat, too, and I got
really wet. I was afraid my mom
would be mad.
That night in bed, I thought:
If I’d set my alarm, I would have
woken up on time.
If I’d studied more for the test, I
would have done better.
If I hadn’t forgotten my lunch, I
wouldn’t have been so hungry.
If I’d remembered my coat, I wouldn’t
have gotten wet.
Tuesday
I got my test results. I came out on
top of the class! It wasn’t such a bad
day, after all. I’ve decided to stop
worrying so much!

Would you change anything in your
life?
Yes. I wish I hadn’t been scared of the
sea when I was young. My friends
loved the water, but I didn’t like
swimming. I used to watch them and
think, “If only I could do that.” In fact,
I still don’t like it … so yes, I wish I
could swim!
No, I don’t want to waste my time
thinking “If only I wasn’t so short …”
or “I wish I had more money … .” In
the end, the only thing that matters
is, are you a good person? Don’t
regret anything!
Yes, I wish I had traveled more. I’m
scared of flying and when my friends
go on vacation I always think, “I wish
I could go, too.” I’ve seen places in
this country, but if only I had visited
more places overseas – that would
have been wonderful. And I wish
I had learned to speak a foreign
language!

I wish I hadn’t been so scared of
heights. When I was a girl, I was
terrified of high places. Tall buildings,
theme park rides, the top of an old
castle—they were impossible. I don’t
know why. My friends used to go
hiking in the mountains near my
house, but I couldn’t go up.
If only I hadn’t felt so scared of
heights, I would have seen more
things.
What happened?
I saw a doctor when I was twenty
years old, and he cured me! It didn’t
take very long. So I wish I had asked
for help much earlier. I wish I hadn’t
spent years feeling scared and
pretending to be brave. And I’m still
OK. This year, even though I am 72,
I’m going on a skiing vacation, and I
will take the ski lift!

I’m Carla and I live in Miami, near
the sea. The sea is very important
to my family. My father has a boat,
and he takes tourists fishing. He left
this morning with some tourists,
and is probably sailing on the open
sea right now. I love surfing, and
do it every day. The day before my
accident I had surfed for two hours.
I had left the house at ten and didn’t
get back until lunchtime.
Let me tell you about the accident. It
was a warm day, and the waves were
perfect. I was surfing like an expert.
Suddenly, a big wave hit me, and I
went under the water. The next thing

I remember, I was lying on the sand.
My friends told me that a dolphin
had saved me!

So you are Carla’s dad?
Yes, that’s right. I was sailing with
some tourists when the accident
happened. I had left that morning

quite early.
So, was Carla on her own, then?
Yes, but that had never been a
problem before. She’s a strong
swimmer and an expert surfer.
So were you surprised to find out she
had had an accident?
Yes, I was.
Was she wearing a life jacket?
No, she wasn’t, but she’s surfing now
and she’s wearing one!
Do you believe that a dolphin saved
her?
