C

Along the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly, flies like a fat chicken, eats green leaves, has the stomach of a cow and has claws (爪) on its wings when young. They build their homes about 4.6m above the river, an important feature (特征) for the safety of the young. It is called the hoatzin. In appearance, the birds of both sexes look very much alike with brown on the back and cream and red on the underside. The head is small, with a large set of feathers on the top, bright red eyes, and blue skin. Its nearest relatives are the common birds, cuckoos. Its most striking feature, though, is only found in the young. Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip. Using these four claws, together with the beak (喙), they can climb about in the bushes, looking very much like primitive birds must have done. When the young hoatzins have learned to fly, they lose their claws. During the drier months between December and March hoatzins fly about the forest in groups of 20 to 30 birds, but in April, when the rainy season begins, they collect together in smaller living units of two to seven birds for producing purposes.

63.What is the text mainly about?

A.Hoatzins in dry and rainy seasons.

B.The relatives and enemies of hoatzins.

C.Primitive birds and hoatzins of the Amazon.

D.The appearance and living habits of hoatzins.

Passage Two

Only one animal can walk 200 miles without stopping once to rest. It would take a person two days and two nights to walk this far, and only one man has ever done it without stopping. What amazing animal has such endurance? The camel! The camel is well known for something else, too. It can cross an entire desert without a single drink of water. Its body is built in a special way to help it store water and food.

A person has just one stomach, but a camel has quite a few. Within each stomach are layers and layers of cells. These cells are like tiny water balloons, storing liquids until the camel needs them. When the camel drinks, the cells grow larger and larger. For a whole week, they can keep the animal's thirst away by sending water to all parts of its body.

And did you ever wonder why the camel has a hump? The hump is a storage place for fat. Because it has this storage area, the camel does not need to eat very often. When the animal needs energy, the layers of fat serve as fuel to keep it going on the long, hot days in the burning sun.

The camel has one other gift that makes it well suited to arid regions. This gift is its amazing nose. A camel can smell a water hole from miles away!

When a camel moves it sways from side to side like a ship on a wavy ocean. Because of this swaying motion, the camel has been called the "Ship of the Desert."

40. The camel's hump is a storage place for ______.

A. muscles

B. extra water

C. body sugars

D. fat
