各位英语高手我现在学习新概念第三册，55课现在遇见自己不懂的一个句子需要大家帮我解答下。。。。。。 Imagine a star up t twenty times larger, brighter, brighter and hotter than our own sun. A planet would have to be a very long way from it to be capable of supporting life这句话书上翻译为，设想一下，一颗恒星比我们的太阳还要大，还要亮，还要热20倍，那么一颗行星为了维持生命就要离开的它的恒星非常远。Imagine a star up t twenty times larger, brighter, brighter and hotter than our own sun我知道这句话是比较级twenty times 难道是20倍的意思吗？？？from it to be这里的it 是否指恒星////
