III/ Reading:
* Read the passage below and choose one correct answer for each question.
The Whale is the largest mammal in the world. Since the whale is shaped like a fish, why is it still
considered a mammal? The fact is that the whale did live on land a very long time ago. However, during its
thousand of years of living in water, the whale gradually become structure like a fish. Thus, the whale has
adapted to marine life. Nevertheless, though the whale resembles the fish externally, it still has the
characteristics of a mammal.
One important difference between the whale and a fish is that the baby whale is born alive. It is not
hatched from an egg. Furthermore, the baby whale is fed on its mother’s milk that like other mammals.
Unlike other sea creatures, the whale is a warm blooded animal. It keeps itself warm in the cold water
with a layer of blubber. ‘Blubber’ is a layer of oily tissue that protects the internal organs and retains heat.
