They close up their leathery leaves to form an insulating blanket 它们合起革质叶片形成一道保温层

199. turning the mountainside into a garden of ice.
     山坡变成了冰雪花园
200. Everything freezes,
     一切都冻结了
201. but the cabbage groundsels have a way of protecting themselves.
     但是木本千里光有办法保护自己
202. They close up their leathery leaves to form an insulating blanket
     它们合起革质叶片形成一道保温层
203. that shields their vulnerable central bud.
     以保护中心脆弱的蓓蕾
204. Night comes to an end...
     寒夜将尽
205. ...and the sunshine returns.
     阳光回归大地
