　　2 (河南省信陽(yáng)商城高中高一月考) 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(遠(yuǎn)古的) birds must have done. When the young hoatzins have learned to fly, they lose their claws.

　　3(湖北省監(jiān)利中學(xué)高一第一次月考) SNAKES(蛇)

　　Some snakes eat other snakes, even poisonous ones. The poison does not do them any harm(傷害). Snakes can swallow(吞下) things that are bigger around than they themselves are. This is possible because the jawbones(腭骨) are loosely joined, and the mouth can stretch(伸展)to make room for a fat animal. The snake’s slim body stretches to make space for the animal when it is inside.

　　Many snakes eat birds’ eggs or frogs(青蛙). Others eat pests(害蟲), mice and other animals that harm crops on farms. Because snakes do this valuable work, you should never kill one. It is too dangerous for you to kill a poisonous one. Leave that job to experts.

　　4(江西省吉安高一第一次段考) The World's Largest Insect

　　This giant insect can be used as a toy.

　　A child ties one end of a string to a stick and the other end around the "neck" of an insect. Holding the stick, the child lets the insect go. With a loud whirring sound, the insect takes off, pulling the string in a large curve over the child's head. The child laughs as the stick jumps around. The child is African, and the toy is the African Goliath beetle, the largest insect in the world.

　　The Goliath is a true insect because it has six legs and a body that is divided into three parts. Like all beetles, it has two pairs of wings. The front pair are thick and stiff and protect the back pair, which are soft. It is these soft back wings that make the beetle fly forward. They also cause the loud whirring sound the beetle makes when it flies. To steer, the beetle twists and turns its legs the same way you steer a bike by turning its front wheel.

　　African children often use the Goliath beetle as a toy. Although it is over 15 centimeters long, it is quite harmless.
