    Have you ever seen the film Traveling Bird? In the film, groups of birds fly high above the sky and cross

the way above snow, rivers, fields, sea and grassland. I'm sure you will love the beautiful picture when you

see the film.

    But you may not feel so good if you have learnt about bird flu (禽流感) from TV or on the Internet. Some

governments had to kill chickens in their cities. A large number of chickens and even some people died in Asia,

and nearly 8,500 birds died in Russia because of bird flu.

    Chickens can get bird flu from the feces (粪便) of the passing birds. It is not so difficult to control (控制)

the chickens in cages or on farms. But it is much more difficult to control the birds in the sky. 

    Luckily, scientists have found a medicine for bird flu. But the virus (病毒) can change easily and quickly.

So bird flu is still a serious problem we must face.

根据上文判断下列句子的正(T)误(F)。

( )1. We know how birds get bird flu from the film Traveling Bird.

(     )2. Not only birds and chickens but also man can get bird flu.

(     )3. The feces of the passing birds can not cause bird flu.

(     )4. It is easier to control chickens than to control flying birds.

(     )5. Scientists have found the medicine, so we needn't worry about bird flu any more.
