VIII. Read and match sentences A-F with gaps 1-5 in the text. There is one extra sentence.
Polar bears live where the ice meets the sea in the Arctic Circle. They are born on land, but they spend most
of their time in the water. (1) ……………………………… However, the polar bear is specially adapted for life
in such a cold place.
The most important adaptation is their fur. A polar bear's fur has both long and short hairs, which means that
it is very thick. This thick fur keeps the bear warm on the land and stops it getting wet when it is swimming.
(2) ……………………………… This means that the bear appears to be white like the snow and ice around it.
The skin under the fur is black. Because of its colour, the skin absorbs the sun's heat and gives the bear
extra warmth.
Under a polar bear's thick fur and black skin is a layer of fat. This layer can be up to 12 cm thick and it
protects the bears from the cold. (3) ……………………………… Polar bears hunt seals for food and these
are difficult to find in the summer when the ice melts.
The shape of a polar bear’s body is also especially designed for the life in the Arctic. (4)
……………………………… All of their body is covered with fur except for the end of their nose. Their round
shape stops the body from losing heat and it helps the bears tolerate the cold.
Polar bears also have fur on the bottoms of their feet, which are enormous. (5) ………………………………
The fur helps the bears walk in the soft snow and also stops them from falling on the ice. The size of their
feet helps them to swim faster, too.
A. Polar bears have a very large body with a small head and very small ears.
B. The hairs are transparent and so the reflect the light from the sun.
C. Sometimes the bears can get too hot, so they jump into the water to cool off.
D. They look like giant snowshoes and they work in the same way.
E. The temperature in the Arctic can be as low as -45ºC in the winter.
F. The bears can also use it for energy when there isn’t anything to eat.
