Who has a long tail

长尾巴───grow a tail;谁───who

Such a large, colourful tail takes energy to grow—resources that could otherwise be put to survival.───要长出如此硕丽的尾巴肯定要耗费一定的能量，而这些能量原可以更好地被用作生存之本。

Hope and trust is the tail of a lizard, even if they are severed, they can grow up again.───希望和信任是蜥蜴的尾巴，即使被切断，但他们还会再长出来。

I can grow to be 5 feet tall with a 3-foot long tail.───我能长到5英尺高，尾巴3英尺长。
