(C)If you are lucky enough, you may find the hummingbird(蜂鸟), the smallest bird of the animal world, in a south American forest.

Though the hummingbird is no bigger than a bee and weighs only 2 to 3 grams, it can fly as fast as 50 metres in a second. It can fly forwards as most birds do, and it can fly backwards as well. The strangest thing about it, however, is that it can stay still in the air, just like a helicopter(直升飞机).

Whenever a hummingbird needs food, it will fly slowly towards a flower. It won’t stand on the flower, as bees would, but just hangs to the flower and then begins to sunk(吸吮) the honey from inside the flower.

The hummingbird is very particular in building its nest(巢). It takes great trouble to choose material, preferring soft ones to hard ones. Its eggs are so small that a common match box can hold as many as one hundred of them..

D. people are making rules in order to fight pollution

(B)The giraffe is the tallest modern land animal. It can be over 5.5meters tall. Its neck alone may be 1.9 meters long. Yet the giraffe has only seven bones in its neck, the same number as in the human. Even a small bird has many more bones in its neck than in a tall giraffe. Each bone in a giraffe’s neck is very long, while the bones in a human neck are small. That makes the difference. A female(雌的)giraffe gives birth to one baby at a time. The baby called a calf, is about1.9 meters tall at birth. By the age eight it is full-grown. The giraffe eats mostly leaves. Because it has a long neck, it can reach the leaves high up on the tree.
