这是根据实际情况回答问题：
What's your favourite food?  Why?
   1.是It's eggs还是They're eggs.?
   2.用I like eggs best.不用best 可以吗？回答Why?时必须用It's deliciouse 还是  They're deliciouse.
同样：What's your favourite animals?应该如何回答？

1.当然They're eggs.
  2.用I like eggs best.不用best 也可以。回答Why?时当然也是They're deliciouse.

同意！！！！！！！！！！！！！！！！
