因为原著为美国人所写,单词采用美式拼法,不抄全文,然后听写单词或词组(用[-No-]表示)以及句子(用[---No---]表示)。请边听写边理解文意,根据上下文注意各句标号,这样有助于提高正确率。

The reason we can be reasonably confident that such an event won't happen in our corner of the galaxy, Thorstensen said, is that it takes a particular kind of star to make a supernova in the first place. A candidate star must be 10 to 20 times [-1-] our own Sun and "we don't have anything of the requisite size that's that close. The universe is a mercifully big place." [---2---]. But Betelgeuse is 50,000 light-years away.
[---3---] One was a blast in 1054 that created the Crab Nebula. Another, in 1604, made a star bright enough to be seen during the day for over three weeks. The most recent was in 1987, when a supernova [-4-] in a zone of the cosmos known as the Large Magellanic Cloud, but that was only [-5-] visible and only in the southern hemisphere — and it was a comfortably safe 169,000 light-years away.

The nearest likely candidate he added, is Betelgeuse, whose various sputterings have for years suggested that something interestingly unstable is going on there
Only half a dozen times in recorded history have supernovae been close enough to be visible to the naked eye.

索尔斯坦森说,有理由相信,这种事情在星系的我们这个角落里不会发生,这是因为,首先,形成一颗超新星要有一种特别的恒星。恒星非得要有我们的太阳10-20倍那么大小才有资格,而"我们附近没有任何符合这个条件的星球"。非常运气,宇宙是个大地方。他接着说,离我们最近的、很可能有资格的,是猎户座;多年来,它一直在喷出各种东西,表明那里不大稳定,引起了大家的注意。但是,猎户座离我们有5万光年之远。
在有记载的历史上,只有五六次超新星是近到肉眼看得见的。一次是1054年的爆炸,形成了蟹状星云。另一次是在1604年,创造了一颗亮得在3个多星期里连在白天都看得见的恒星。最近一次是在1987年,有一颗超新星在宇宙一个名叫大麦哲伦云的区域闪了一下,然而仅仅勉强看得见,而且仅仅在南半球看得见--它在16.9万光年以外,对我们毫无危险。
