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(远古的) 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.

2.Young hoatzins are different from their parents in that____ .

C.they eat a lot like a cow

D.they live on river banks

3.What can we infer about primitive birds from the text?

A.They had claws to help them climb.

B.They could fly long distances.

C.They had four wings like hoatzins.

D.They had a head with long feathers on the top.

4.Why do hoatzins collect together in smaller groups when the rainy season comes?

阅读下面短文,从短文后各题所给的四个选项(A、B、C和D)中,选出可以填入空白处的最佳选项。

A few years ago, my younger brother and I went to Norfolk, Virginian by plane. , before we took off, we heard the pilot's voice throughout the plane, “Sorry, ladies and gentlemen. We have no on the plane. We have a generator(发电机), and we are going to the engines with it. We will in the air and head to Norfolk, and see what happens. ”

See what happens? We are going to get up in the air, and see what happens? At this point, one woman started crying. “Oh, no! We are going to !” There were sighs of and anxiety quickly spreading throughout the plane, and we hadn't even yet. Thirty minutes passed and we were still there. Then the voice of the pilot came over again,“ Ladies and gentlemen, I know you are , so are we. We only have one engine going right now, and it is working double time.”

There was crying we had walked in to grave(坟墓). But the pilot told us our one engine was working double time, and his was to get up in the air and see what happens! Then we did. We got up in the air and happened. We arrived in Norfolk and everyone for still being alive.

Although I do sincerely like to have a plan “see what happens”, it really isn’t such a bad life strategy. All too often, I would see people pursuing their goals with inaction just because they don’t have success. Actually, success will never be guaranteed. The thing that you can do is just get up in the air, and see what hap­pens.

If you are planning to learn a new skill, “get up in the air, and see what happens!” It might not be as as you thought. You might be smarter than you thought, and the result could be very ! So don’t stay there trying nothing just because there is no of guaran­teed success.
