<P>What's your favourite food?(粽子）</P>
<P>It's&nbsp;rice dumplings.&nbsp;还是They're rice dumplings.</P>

直接用拼音。见电子课本

我觉得是：It's rice dumpling.
dumpling是可数的

用音译ZongZi,然后打上括号解释下什么是粽子
比如ZongZi(rice dumpling wrapped in reed leaves which Chinese people eat on the fifth day of the fifth lunar month)
以前我们学口译的时候就是要求这样翻译的
