Have you ever wondered why different animals or pests have their particular colours? Colours in them seem to be used mainly to protect themselves.

       Birds, especially seagulls, are very fond of locusts, but birds cannot easily catch locusts because locusts change their colours together with the change of the colour of crops.When crops are green, locusts look green.But when crops are ripe, locusts take on exactly the same brown colour as crops have.Some other pests with different colours from plants are usually easily found and eaten by their enemies.So they have to hide themselves in terror for lives and appear only at night.

       If you study the animal life in any part of the world, you will find the main use of colouring is to protect themselves.Bears, wolves and other beasts move quietly through forests.They are usually invisible to the eyes of hunters, because they have the colour much like the barks of trees.

       An even more strange act remains to be noticed.A kind of fish living in seas can send out a kind of very black liquid when it faces danger.While the liquid spreads over, its enemies cannot find it, and it immediately swims away.Thus, it has existed up to now though it is not powerful at all.

1.This passage mainly talks about ________.

       A.the change of colour in locusts                                                                            

       B.the protective coloration of animals and pests

       C.how a certain sea fish protects itself     

       D.a(chǎn)nimals or pests can dye themselves different colours

2.Locusts are ________ but they are not easily wiped out by their enemies because ________.

       A.a(chǎn)nimals; they are powerful enough                                                                       

       B.beasts; they are dangerous to their enemies

       C.pests; they take on the same colours as crops                                                

       D.birds; they fly extraordinarily fast

3.The pests that have different colours from plants usually appear at night because ________.

       A.their enemies can easily find them and eat them

       B.they have the habit of coming out in darkness

       C.it’s easy for them to destroy plants in darkness

       D.birds take their rest when night comes

4.Bears and wolves have the same colour as barks of trees because ________.

       A.they fear other beasts                                                                                                

       B.they like brown or grey colours

       C.they enjoy walking through forests quietly

Today, we talk to an up-and-coming (有前途的) erhu player, Lee Hang, from Hong Kong. He’ll play with the Hong Kong Orchestra (管弦樂隊) next Sunday in a special concert by young Chinese musicians.

Interviewer: Thank you for talking to us, Lee. You must be very excited.

Lee: Yes, I am. This is the first time that I’ve played with such a famous orchestra and in front of so many people. They’re expecting about 4,000 people.

Interviewer: Does that scare you?

Lee: To be honest, yes. I haven’t slept much in the last few days. But my teacher told me I wouldn’t take it seriously enough if I wasn’t scared. That helped a lot.

Interviewer: Tell me about why you started playing the erhu.

Lee: My parents took me to piano and violin lessons. I quite liked them but they had to force me to go sometimes. One night, I saw a documentary about Yo Yo Ma, the famous Chinese American cello(大提琴) player. He talked about his love of Chinese instruments and we should follow our interests. I always enjoyed listening to Chinese instruments like the erhu and guzheng. That inspired me to learn the erhu. My parents were glad that I was playing something I actually liked.

Interviewer: What do your friends think of you playing a Chinese instrument?

Lee: Well, a lot of my classmates think playing things like the erhu isn’t cool. I don’t care. It makes me happy. I got a letter from Yo Yo, saying how much he admired me and that he’d like to meet me next time when he’s in Hong Kong. They thought that was pretty cool!

Interviewer: And what does the future hold for you?

Lee: I’d like to study music in a university in China then hopefully play in orchestras. My ambition is to bring the beautiful sound of the erhu to all the corners of the world.

Interviewer: Well, if anyone can, it’s you. Thanks for talking to me, Lee. Good luck.

Lee: Thanks.

What will Lee Hang do next Sunday?
