The desert is called the Namib Desert. This desert is believed to be nearly 40 million years old! It is truly an ancient desert. The Namib Desert has some of the world's biggest sand dunes (沙丘). The dunes tower high into the sky. One dune, called “Big Daddy”， is almost 1,200 feet (365 meters) high! This means “Big Daddy”is bigger than a 100 story building! People can climb“Big Daddy”. One man climbed to the dune's crest, or top. Near the crest, the man had to climb on all fours! He had to use his hands to prevent himself from sliding down. The Namib Desert's ancient dunes vary in color. When something varies, it changes and becomes different. The Namib Desert dunes vary from orange to red. During the day, the surface temperature of the sand dunes heats up. The surface temperature can heat up to 54 ℃. What does one lizard (蜥蜴) do to keep its feet cool It stands on only two feet at a time! It jumps from pair to pair! This allows the feet in the air to cool off. When this isn't enough, the lizard dives into the sand. It digs down to where the sand is cooler. Little water falls on the dunes. Often there is less than half an inch (1.3 centimeters) of rain a year. What does one dune plant do for water It uses the morning fog (雾)! The fog comes from the Atlantic Ocean nearby. It rolls across the dunes. The plant's leaves are filled with empty spaces. The empty spaces take in droplets (小水珠) of the water. The plant can survive years without rain by taking in the fog droplets. 1．What is the Namib Desert most famous for A．Its old age. B．Its big size. C．Its location.
