Read the passage
carefully and answer the questions that follow.
Unlike most of the fightless birds, penguins are skilled swimmers. Four of the
best-known species are the Emperor, Adelie, Chinstrap and Rockhopper penguins.
Penguins walk awkwardly on land. They walk with a clumsy waddle or a hop. To
move faster, they slide on their bellies when they go downhill. However, penguins
are graceful and move fast in the sea. They use their webbed feet as rudders to
change direction. Their feet are also used as brakes. Most penguins do not eat
at all times of the year. When they are breeding, they may go for weeks without
feeding. For the Emperor species, they can last for months without eating.
Before breeding, penguins feed constantly to build up a reserve of fat.
