Visitors to the zoo usually pity the animals owing to their particular emotional associations(联想). Which animals should be indeed pitied?

The first type are those clever and  56  developed animals  57  lively intelligence and desire for activity can  58  no outlet behind the bars of the cage. Those animals living in a free state before  59  in the zoo have a strong desire for moving about  60 , but have to turn around repeatedly in their quarters. Owing to this disappointment, foxed and wolves  61  in places which are far too small, are among the most  62  of all zoo animals。

Another sad scene, seldom  63  by ordinary zoo visitors, is the  64  flying trials of swans(天鹅)

At migration(迁途) time. These creatures, like most other water birds, are generally made unable to fly by the  65  of cutting off a tip of the wing bone.  66 such swans in the zoo generally seem happy under  67  care and they raise their young without any trouble, at migration time things become  68 . The birds never really  69  that they can no longer fly, and repeatedly swim to the  70  of the pond so that they can have the whole extent of its surface when trying to  71 against the wind. Meanwhile, their loud flying calls can be heard as they try to  72 , and again and again the grand preparations end in  73 .

I do not like seeing those  74  water birds in the zoo. The missing tip of one wing and the still sadder picture that the bird makes when it  75  its wings hurt me badly. What a truly sorry picture it is.
