19、mmon 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 bi
20、rds 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
21、birds for producing purposes.When danger comes in the form of a snake or a monkey，the young hoatzinsmaybe three in one familyjump over the side and into the river.

25、their young.BAndy rode slowly on his way to school，daydreaming about the fishing trip that his father had promised him. He was so busy dreaming about all the fish he would catch that he was unaware of everything else around him.He rode along until a strange sound drew him to the present. He came to
26、a stop and looked curiously up to the heavens. What he saw shocked and terrified him. A huge swarm of bees filled the sky like a black cloud and the buzzing mass seemed to be heading angrily towards him.With no time to waste，Andy sped off in the opposite direction，riding furiouslybut without knowing
27、 how to escape the swarm.With a rapidly beating heart and his legs pumping furiously，he sped down the rough road. As the bees came closer，his panic increased. Andy knew that he was sensitive to bee stings(蜇). The last sting had landed him in hospitaland that was only one bee sting! He had been force
28、d to stay in bed for two whole days. Suddenly，his fathers words came to him. “When you are in a tight situation，dont panic. Use your brain and think your way out of it.”On a nearby hill，he could see smoke waving slowly skywards from the chimney of the Nelson family home. “Bees dont like smoke， ” he
29、thought. “They couldnt get into the house.” Andy raced towards the Nelson house，but the bees were gaining ground. Andy knew he could not reach the house in time. He estimated that the bees would catch up with him soon.Suddenly，out of the corner of his eyes，he spotted a small dam used by Mr. Nelson t
30、o irrigate his vegetable garden. Off his bike and into the cool water he dived，disappearing below the surface and away from the savage insects. After holding his breath for as long as he could，Andy came up for air and noticed the bees had gone. Dragging himself out of the dam，he struggled up the hil
31、ly slope and rang the doorbell. Mrs. Nelson took him inside and rang his mother.“Youll really need that fishing break to help you recover， ”laughed his mother with relief.“Thank goodness you didnt panic！” But Andy did not hear her. He was dreaming once again of the fish he would catch tomorrow.50Why

35、or your local environment?As early as next year it may well be possible.When you have finished with your mobile phone you will be able to bury it in the garden or a plant pot and wait for it to flower.A biodegradable mobile phone was，this month，introduced by scientists.It is hoped that the new type
36、of phone will encourage consumers to recycle.Scientists have come up with a new material over the last five years.It looks like any other plastic and can be hard or soft，and able to change shape.Over time it can also break down into the soil without giving out any harmful chemicals.British researche
37、rs used the new material to develop a phone cover that contains a sunflower seed.When this new type of cover turns into waste， it forms nitrates(硝酸盐) These feed the seed and help the flower grow.Engineers have designed a small transparent window to hold the seed.They have made sure it only grows whe
38、n the phone is thrown away.“Weve only put sunflower seeds into the covers so far.But we are working with plant experts to find out which flowers would perform best.Maybe we could put roses in next time， ”said one scientist.As phone technology is developing so quickly people are always throwing their
39、 mobiles away.This means manufacturers are under pressure to find ways of recycling them.Some 650 million mobile phones have been sold this year.Most of them will be thrown away within two years，adding plastic，heavy metal and chemical waste to the environment.A biodegradable cover can offer some rel
40、ief for nature，according to the scientists.“The seed is released and the flower grows in the pot so you dont have to concern yourself with the phone when you have finished using it， ”said Kerry Kirwan.She leads the research team，which is based at the University of Warwick in Britain.54After you have

45、ll phoneDEvery year more people recognize that it is wrong to kill wildlife for “sport”Progress in this direction is slow because shooting is not a sport for watching，and only those few who take part realize the cruelty and destruction.The number of gunners，however ，grows rapidly.Children too young

47、magazines with stories honoring the chase and the kill.In school they view motion pictures which are supposedly meant to teach them how to deal with arms safely but which are actually designed to stimulate(刺激 ) a desire to own a gun.Wildlife is disappearing because of shooting and because of the loss of wildland habitat(栖息地)Habitat loss will continue with our increasing population，but can we slow the loss of wildlif
