1 Read about two of the biggest shopping
centres in the world. Which one do you
think is the most interesting?
West Edmonton Mall
West Edmonton Mall is a shopping centre in
Canada. It's really big! You can spend your holidays
in this shopping centre because there are hotels,
cinemas, a water park, and lots and lots of shops.
Teenagers like to spend the day in Galaxyland. This
is the largest indoor amusement park in the world.
There are 24 rides and places to play. You can play
mini-golf or go ice skating. You can swim and go
down 21 slides in the water park. The weather is not
important because everything is inside. Do you like
films? There are 13 different films at the cinema every
evening. Come to see this shopping centre. It's open
365 days a year.

Dubai Mall
BUYING THINGS
The Dubai Mall is in the United Arab Emirates.
It opened in 2008 and now has more than
1,200 shops. There are 200 restaurants as well.
Families can spend time in the shopping centre
because there are a lot of activities for young
people. One of the best places to go is the
aquarium. You can stand in a tunnel under the
water and see the fish swimming above you,
or you can ride in a boat with a glass bottom
and see the fish underneath you. Another great
place for teenagers is Kidzania. This is a little city
where you can try different jobs. You can be a
dentist, a police officer or work in a restaurant or
a supermarket. You sell and pay for things with
special money. It's a great place!
