书面表达。

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?
