（单词翻译）

 One giant short-faced bear is more than a match for two lions. But in this bitter climate, lions can’t afford to go without a meal for long. A mammoth¹ calf² in its first winter is a tempting³ sight. But mammoths are attentive⁴ mothers and they have the back-up of their herd⁵. The calf is ringed by vigilant⁶ relatives. The lions try to find a loophole. The mammoth’s matriarch, the oldest female, takes control. And she has 60 years’ experience of putting lions in their place. In the bosom⁷ of their close-knit family, the calf is safe, from predators⁸ at least.
