【解析】：
这是一道英语填空题，考查的是对英文歌谣的理解以及根据上下文补全歌谣的能力。学生需要根据歌谣的内容和语境，结合图片提示（虽然具体图片未给出，但题目描述暗示了有图片作为提示），填写合适的单词使歌谣完整。这类题目主要测试学生的词汇量、语法知识和语境理解能力。
【答案】：
When we go to the zoo，
There are a lot of animals to see.（考查there be句型，animals为复数，所以用are）
Giraffe（长颈鹿）with a long neck，（长颈鹿有长脖子，所以填long）
Eating leaves on a tree.
When we go to the zoo，（根据上文可知这里还是描述在动物园，所以填zoo）
We watch the animals play.
Penguins（企鹅）jumping in a pool，
Eating fish all day.（企鹅吃鱼，所以填fish）
Black-and-white pandas rolling about（翻滚），（熊猫是黑白相间的，所以填white）
Eating sticks of bamboo（竹子）.
But I really love the zoo，（根据上文和语境，这里表达的是对动物园的喜爱，所以填zoo）
