Hi Laura,
How are you? I’m great!
I’ve been working for the past year

as an intern at our local zoo. It’s
fantastic. I’ve been doing lots of
interesting things. I’ve been working
with lots of different animals in
Pets Corner. My favorites are the
meerkats. I’ve been feeding them.
And I’m part of a group of interns –
we have been preparing handouts
for children who come to the zoo
on a school trip. It’s been good fun.
What have you been doing this
summer? Have you been working?
I’ll write again soon and send some

C
My name’s Selma. I’m a student at
an international school in Turkey.
I’ve been a member of the World
Wide Fund for Nature (WWF) for
years – since 2011. I joined because
I liked the logo. Have you seen
it? It’s a picture of a panda, and I
was crazy about pandas. But now
I understand how important the
WWF is, and I’m proud that I’m a
member. The WWF started in 1961,
and it has become one of the most
important organizations in the
world for conservation. Its members
have raised money to protect
animals’ habitats, and they’ve held
campaigns to protect the tigers.
Right now they are working in
Brazil to help protect the Amazon
rainforest. Their work is continuing,
all over the world. The other reason
I like the WWF is because I know so
many children around the world like
me are members, too. It isn’t just for
grown-ups. We are doing something
really important for our planet.

Where did bearded vultures live?
In the past, bearded vultures lived
in the Alps, which are a range of
mountains in southern Europe.
Did they live in South America too?
No, they didn’t live there.
When did they die out in the Alps?
In 1913, humans killed the last
bearded vulture in the Alps.
Did people kill the vultures by
accident?
Unfortunately, people didn’t kill the
birds by accident. People hunted the

birds with guns and poison.
What did the WWF do to help?
In 1978, the WWF started a project to
raise the birds in zoos.
Was it easy?
No, it wasn’t. It took a long time.
When did they release the first
chicks?
In 1986, they released some young
birds in Austria, and then into
some other countries as well. They
didn’t release them into the Alps
immediately.
Was the project successful?
Yes, it was! Today there are more
than 100 breeding pairs of bearded
vultures in Europe.

Frequently Asked Questions
How could cave people keep their
teeth clean if they didn’t have
toothpaste and toothbrushes? P
They couldn’t go to the dentist, but
they could clean or pick food out of
their teeth with sticks or bones. P
Could cave people find food very
easily? P
They couldn’t just go to the
supermarket like us, but they could
hunt, and they could also find fruit
and berries in the forests. They also
knew which plants you could eat and
which ones you couldn’t because

they were poisonous. P
In the future, will we be able to find
out more about people who lived
20,000 years ago? F
Yes, in the future we will be able to
know even more about these
people, because of carbon dating
and DNA. F
Will we be able to learn more about
what these people ate and how they
communicated? F
We will probably be able to find
out what they ate, because of
new scientific discoveries, but we
probably won’t be able to discover
anything about the language they
spoke. F
C

Mr. Batty, you say you have studied
the cave people for a long time.
Yes, that’s right. It has been
interesting. I have learned a lot about
their way of life.
Could they communicate with each
other easily?
Yes, of course. They could also speak
perfect English, as well as their own
language.
Really? That’s amazing. And could
they also write English?
Yes, but they couldn’t spell very well,
and they couldn’t use a dictionary.
Could they live comfortably in their
caves?
Yes, they could. Most of the caves
had a bathroom and a kitchen, so

they could take a bath or a shower,
and they could cook food like we
do. They didn’t have refrigerators
though, so they couldn’t store meat
for very long.
So you are telling us they had
electricity?
Yes, they could light their caves
like we do, but they couldn’t install
central heating.
Did you find any evidence of all of
this?
No, I couldn’t take any photos. I
forgot to take my camera with me.

Today we are talking about
dinosaurs. They have found dinosaur
bones near the school, so this part
of the country must✓ be where
dinosaurs lived before.
Can you look at number 1 on the
photo? The bone at the top of the
photo must✓ be the dinosaur’s tail,
and bone number 2 next to the tail
has to be its backbone. We know
this for sure because we can look at
photos of bones found before.
And now can you look at number 3
at the bottom of the photo. We know
that the two large bones have to be
the top of the dinosaur’s legs. We
think that bone number 4 near the
man’s tray might be the bottom part
of the leg, but we are not completely
sure. Are there any questions?
Is that small object on the left of the
photo one of the dinosaur’s teeth?
No, it can’t be one of its teeth. Look
more closely. It’s the man’s hammer!
C
They think it’s true that bone number
4 is the bottom part of the leg.
They know that it is true that bone
number 1 is the dinosaur’s tail,

bone number 2 is its backbone, and
bones number 3 are the top of the
dinosaur’s legs.

What do you think this is? It looks
like part of a toy to me.
It can’t be because it’s made out of
gold. It must be something else. I
think it might be a ring, but I’m not
completely sure.
Maybe you’re right. And what about
this broken pot? I’m sure that it must
be very old.

No, it can’t be old. Look, it’s made of
plastic!
And I’m not sure, but these round
objects might be coins.
Yes, they must be. Look, there’s a face
and some writing on them. I think
this might be Roman treasure.
No, it can’t be. The Romans didn’t
come to this part of the country.

In our next program, we are going to
look at a new invention, the
“Copterbike”, which we believe will
be a bestseller. Why?
It will work as a motorbike and will
travel at 200 miles an hour! It will
change to a helicopter in one minute
and will fly at 400 miles an hour! You
won’t need to be a pilot to fly it, and
you won’t need to wear a helmet
because there will be an airbag to
protect your head. We predict the
following with the “Copterbike”:
There will be fewer accidents.
People will get to work quicker.
Drivers will enjoy flying.
Good night, everybody. Next week,
I am going to drive and fly the
“Copterbike” myself, so I will be
able to give you my opinion of the
invention. Just have one last look at
this beautiful machine. I think you
can see that I’m going to have lots of

fun! See you next week! Bye.

Next week after school, Sultan and
I are meeting to design our model
spaceship for the competition.
Jack and I are also planning our
design next week, and we’re hoping
to finish the drawings on Friday.
We’re finishing our drawings at
the beginning of March and then
we’re making a test spaceship the
following week.

So you’re testing the spaceship to
see if it flies in March?
Yes, and if everything goes well,
we’re building the real spaceship in
June.
I think that’s very late. The
competition is in July!
So when are you building your
spaceship?
We’re starting to build it at the end
of March and we’re adding the solar
panels at the beginning of April.
We’re planning to finish the whole
spaceship by the middle of May. And
we’re testing it on June 1

These are leafcutter ants. They’re
from Central and South America.
They recycle about 20% of leaves in
the rainforest.
Wow!
They have lots of different jobs.
There are soldier ants, scouts, leafcutters, gardeners, and there is, of
course, the queen.
How many of them live together?

Sometimes over five million ants
live together in a nest. And they are
really strong. They can carry over fifty
times their own weight.
Can they talk to each other?
No, they can’t talk, but they do
communicate. They can warn each
other when there’s danger. And
they tell each other where to find
food. They use their antennae to
pick up smells from other ants. The
smells are called scents. They can
leave about twenty different scent
messages by rubbing their abdomen
(their body) on the ground.

studies wolves. He said that wolves
used their body language and their
faces to communicate. He said that
they used their ears, tails and body
position to share their feelings with
the rest of the pack. I don’t like the
noise wolves make. He said that
the noise was called a howl. I asked
him if howling was a sign of anger.
He told me that wolves howled to
scare other animals away and to
protect their young, but he also said
that sometimes they probably just
howled for fun!

The police thanked 86-year-old
grandmother Mavis Jones yesterday
for stopping a robbery at the City Art
Museum. We interviewed Mavis:
Why did you go to the museum?
I went because it’s nice and warm. I
go there every afternoon.
Who did you go with?
I went by myself.
Where did you see the robber?
He was in the Italian art room, in a
long black coat. I was suspicious. It

was a sunny day. Why did he need a
coat?
What did you do?
I hid behind a statue. I saw him take
a painting and put it under his coat!
How did you stop him?
I shouted ‘Hey! You stop that, young
man!’ He started to run. So I tripped
him with my cane. Then I sat on him.
I shouted: ‘Help, thief!’ I have quite a
loud voice, you know.
Who helped you?
The security guards! They ran in and
rescued the picture. Then they called
the police. It was very exciting!
Congratulations, Mavis. You are our

How did you stop the thief?
I used my cane. And then I sat on top
of him. I was really mad!
What happened next?
I called for help and the security

guards came in. They found the
picture, and they helped me stand
up!
Who called the police? You or the

Brendan thinks it’s important for
scientists to tell people when
a volcano isn’t safe. He studies
volcanoes so that people are told
when it is dangerous in plenty of
time.
Brendan has made a film about
volcanoes. In the film, rocks inside
the volcano melt. This is magma.
Magma is pushed to the top of
the volcano. The ground shakes.
Suddenly rocks, magma, and hot gas
explode into the sky. It’s terrifying.
People hear the noise from far away,
even on other islands.
The eruption is so loud, the noise
is heard a long way away. Hot lava
travels down the mountain at 50
kph. Ash falls from the sky. The
mountain is destroyed.
Brendan’s work helps keep people

safe. People living nearby are taken
to safety, and no one is hurt. Their
houses aren’t damaged, but they
are covered in ash. Their crops are
buried. People can’t return home for
a year.

Hi there. I’m Eva Rojas. I’m a scientist.
I work with Brendan at the Scientific
Observatory. This is where reports
are written and are sent to the local
police. Our job is to make sure the
local people are safe.
Have you ever wondered how
volcanoes are measured? We use
a lot of different instruments, like
seismographs, radio, and GPS
devices. Gas samples are taken
from cracks in the mountain. They
are poisonous, so we must be very
careful!
Here’s my latest report:
5:07 a.m. The ground shakes.
Magma is pushed to the surface.
Gases are escaping.
Our instruments record a lot of
activity. My boss is called at home
and he comes to the center right
away.
6:12 a.m. We are on red alert.
Schools and farms nearby are closed.
People are not allowed near the area.

9:27 a.m. Local people are told to
leave their homes. Many are taken by
bus to shelters in the next city. They
won’t be able to return for a few
days.
3 days later
7:48 a.m. The volcano erupts. But
thankfully, everyone is safe.

When was the village opened?
The idea was discussed in the 1950s
by a group of librarians, and a
collection of maps and old photos
was started. In the 1970s, a plan
was discussed to rebuild a village
on a piece of land which had only
old coal mines and empty factories.
Work began soon afterwards and
a few buildings were erected. Then
in 1980, a tramline was installed to
transport visitors to the center of the
village.
Were lots of other buildings moved

at that time?
Yes, they were. Lots of shops,
houses, and factories were moved
and rebuilt. Even a school, a movie
theater, and a fairground were
opened to the public.
Was everything moved at the same
time?
No, it wasn’t. The fairground and
the movie theater weren’t moved
until later. It’s very complicated.
For example, all the bricks were
numbered and photographed, and
then they were put onto trucks and
taken there.
Is the village complete now?
No, it is developing all the time. A
complete 1930s street, for example,
was added in 2010.
The verb that comes before each
past participle is the simple past
form of be.

Dubai was changed very quickly.
The desert was made into a modern

The roads were constructed for cars,

restaurants were built for visitors.
Many foreign banks and shopping
malls were opened there. Everything
was designed to attract tourists and
business people. In 2009, a tram

installed to transport people quickly

suddenly shouted from the window,
“Don’t worry! I feel fine. I don’t need

Ideas from fifth grade for the school
board
Our school is not very “green” at
the moment. If we did some simple
things, we would save electricity and
would save money.
If the school board discussed our
ideas and made the changes we
suggest, our school would be the
“greenest” in Mexico. We ask the
school board to discuss our ideas
and take action on the best ones.
If we had classes four days a week,
the school would use less electricity.
If we always turned off the lights
when we left a room, we would save
money.
If we stayed at home and had classes
on the Internet, we would be able to

close the school!
If we didn’t use books, we would
save paper.
If we closed the doors and windows

The fifth grade has sent us lots of
ideas how to make our school green
and how to save money. Do you
think they are good ideas?
Yes, I do. If the school did everything
the fifth grade suggested, we would
be really green.
No, not everything! I think some of
the ideas are not very good. If we
had classes online, we wouldn’t have
a school at all!
Yes, that’s right, but maybe if
students had classes three or
four days a week, we would save
electricity!
Yes, the school would save electricity
if we had a shorter school week, but
if we stayed at home, we would use
more electricity there.

The trip to London was long. We
felt excited, but our teachers looked
tired. When we arrived, we had a
snack, which tasted good. We ate
quickly and went to a room where a
scientist explained clearly what we
were going to do.
Then we worked in groups and did
experiments. In the first experiment,
we had three buckets of water: one
cold, one warm and one hot. We put
our hands slowly into one bucket
and then took them out quickly and
put them into another. After putting
your hands into the cold water, the
warm water felt hot. After putting
your hands into the hot water, it felt
cold!
In the second experiment, we closed
our eyes and smelled food. My food
smelled sweet, and I guessed it was
a cake.
In another experiment, they played
songs very fast. All the words
sounded different. It was impossible
to understand them. The music
sounded strange, as well.
We went to bed at ten and they
turned off the lights. Everything

looked scary in the dark.

Are you asleep, Mel?
No, I didn’t sleep very well. I felt very
cold. The room was freezing.
Me too. I heard lots of noises, and the
air conditioning sounded very loud.
Yes, it was very weird.
And the air smelled horrible. Not
like normal. I think it was from
the chemicals we used in the
experiments.
Yes, maybe. And in the dark, the
objects in this room looked scary.
Like monsters! I was frightened.
And my mouth felt strange because
of all the bitter things they gave us
to chew!

Michael Kanu from Senegal –
tightrope and aerial dancing
Is it easy to be a circus performer?
It depends. Sometimes it’s difficult to
learn new routines, but it’s fantastic
to perform in front of an audience.
It might look easy, but it’s difficult to
do well. I love performing, so it’s fun
to be onstage.
Olivia Chen from China – juggling
Do you like touring, or is it better to

stay in one city?
I like touring, because it’s interesting
to visit new places. I like traveling.
But my husband prefers being in one
place, because it’s tiring to travel all
the time.
Selcuk Akpek from Turkey –
acrobatics
What do you like most about being
in the circus?
I love being part of this “international
family”: we come from all over the
world, and we are great friends.
When I first arrived, I couldn’t
understand much. My English
wasn’t very good, and it was hard to
understand lots of different people,
but now it’s fine. This is the best job
in the world.

Hi Anita. It’s nice to meet you.
Congratulations on the show!
Thanks. It’s a dream come true! It’s
hard to tell you how excited I am.
Do you get nervous onstage?
Yes. I’ve tried out for lots of other
shows. Sometimes you are too short,
too tall, your hair is the wrong color,
or they don’t like your voice. It’s
impossible to be perfect for every
part. But then I got lucky! Wow!
Spaceship! is great. It’s fun to do
things with your friends, and the
other actors are my friends now.
Do you sometimes wish you were at
home on the weekends?
Yes, I do. I love playing volleyball,
and I can’t play on my school
team because of the show. It’s
disappointing to miss birthday
parties. But it’s nice to have the
chance to do this.

Hi Tulai,
I went to Disneyland near Tokyo with
my family last weekend. It was a
great trip, but I didn’t enjoy the flight
there.
My brother and I felt scared when
the plane started to take off. We
thought the noise of the engines
sounded strange, but when the
plane was in the air, the engines
sounded normal. The flight was
only an hour, but it felt very long.
We wanted to arrive as quickly as
possible. On the coach journey
from the airport to Disneyland, our
parents looked very tired, and they

soon fell asleep. When the coach
arrived at Disneyland, our parents
looked refreshed again after their
sleep. We went to our hotel and
unpacked quickly. There were some
flowers on the table in our room.
They looked beautiful, and they
smelled fantastic. Then we went to
Disneyland and spent about five
hours on the different rides and
other activities. At night, everything
looked so bright, and the music
sounded great. I’ll tell you more and
send some photos in my next email. I
have to go.
Bye for now,
Amy

Farming was very important to
the castle inhabitants. Everyone
who lived and worked in the castle
needed food and drink, and so did
all the animals. People grew most of
their food in the fields around the
castle. Inside the castle, the kitchen
was an important room. It contained
the fires for cooking. Castles usually
had other rooms for food nearby,
such as the bakery, and rooms where
the cook stored food.
