读写任务。

     阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

     Jackie is perhaps the most easily annoyed koala (考拉) at the Featherdale Wildlife Park in southern

Australia. All the koalas there are unhappy and complaining. You would be too if you were used to night

activities and someone kept waking you up all day while you were trying to sleep it off. That's right-sleep

it off. The average koala is always half asleep because it feeds on the leaves of a special kind that makes

it sleepy.

     The reason Jackie and her fellow koalas are repeatedly awoken from their deep sleep is so they can be

hugged and photographed by tourists, who make the trips to Featherdale and an increasing number of other

national parks for just that special experience. Whatever department in the Aussie government in charge of

such things is now moving to make the practice illegal, which is understandable. How would you react, my

friend, if you were trying to sleep off a dozen times and some round, furry creature smelling of grass kept

waking you?

* 考拉即树袋熊
