收获英语 收获一本好书~!
书本的朗读语音很charming的磁性英音~~~大家可以好好学着模仿哦~~~!!
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。

Zwicky
[---1---] In the early 1930s, he turned his attention to a question that had long troubled astronomers: the appearance in the sky of occasional unexplained points of light, new stars. [-2-]he wondered if the neutron—the subatomic particle that had just been discovered in England by James Chadwick, and was thus both novel and rather fashionable—might be at the heart of things. [---3---] Atoms would literally be crushed together, their electrons forced into the nucleus, forming neutrons. You would have a neutron star. Imagine a million really weighty cannonballs [-4-] down to the size of a marble and—well, you’re still not even close. [---5---] A [-6-]! But there was more. Zwicky realized that after the collapse of such a star there would be a huge amount of energy left over—enough to make the biggest bang in the universe. He called these [-7-]explosions supernovae. They would be—they are—the biggest events in creation.
But Zwicky was also capable of insights of the most startling brilliance.
Improbably
It occurred to him that if a star collapsed to the sort of densities found in the core of atoms, the result would be an unimaginably compacted core.
squeezed
The core of a neutron star is so dense that a single spoonful of matter from it would weigh 200 billion pounds.

然而,兹威基聪明过人,具有敏锐的洞察力。20世纪30年代初,他把注意力转向一个长期困扰天文学家的问题:天空中偶尔出现而又无法解释的光点--新的恒星。令人难以置信的是,他怀疑问题的核心是否在于中子--英国的詹姆斯•查德威克刚刚发现的,因而是新奇而时髦的亚原子粒子。他突然想到,要是恒星坍缩到原子的核心那种密度,便会变成一个极其坚实的核。原子实际上已经被压成一团,它们的电子不得不变成核子,形成了中子。这样就形成了一颗中子星。想像一下,把100万枚很重的炮弹挤压成一粒弹子的大小--哎呀,这还差得远呢。一颗中子星核的密度如此之大,里面的一调羹物质会重达900亿千克。只是一调羹啊!然而,不仅如此。兹威基意识到,这样的一颗恒星坍缩以后会释放出大量的能量--足以产生宇宙里最大的爆炸。他把这种由此产生的爆炸叫做超新星。它们会是--实际上也是--创建宇宙过程中最大的事件。
