黑洞英文绘本

15024 李秋颖 By Daddy 《Pete the Cat: Scuba-Cat》 内容简介： New York Times bestselling author and artist James Dean brings Pete the Cat’s world to life under the sea in this new I Can Read book. Pete the Cat is going scuba diving! Before he hits the water，Captain Joe tells him about all the sea creatures he can encounter，and Pete is super excited to see a seahorse.But when he is suited up and swimming around，he has to search high and low to find the little guy.In this aquatic adventure，Pete makes a new friend and gets a big surprise! 包括《I Can Read!》系列在内，我跟孩子妈给孩子买了很多很多的英文绘本。当初，我们还不了解分级读物跟普通英文绘本的区别。因为孩子英文绘本的阅读起步较晚，从3岁多才开始，且没有持续性，对于买到的《I Can Read！》的高Level版本，总感觉有些难度。而只有My first reading！这一级别的绘本，难易程度是合适的，但对于一个快5岁的男孩来说，趣味性上又难以吸引到他。直到读到《Pete the cat》系列，这只愣愣的猫经历的的故事，让孩子有了各种各样的共鸣，也才有了我们继续亲子共读的可能。 回到这一个故事，Pete去潜水，船长告诉他，如果你幸运的话，可能会见到海马，并说了海马的特征。Pete很兴奋，开始寻找海马。在Pete寻找海马的海底旅程中，他遇到了 a swordfish、a stingray、a blowfish、an octopus……但就是没有找到海马，这时，孩子们可能已经发现，小海马其实一直跟随着Pete呢。这种“灯下黑”的场景，不是很有趣么？且每页都有小海马这样一个小元素，也正契合4岁左右或更小孩子对于小东西的敏感期。后面，Pete为了寻找海马，还闯入了一个黑洞，黑洞里很黑，这种场景，孩子不自然的又开始紧张起来。Pete又遇见了a crab、an eel……洞里越来越黑了，直到Pete什么也看不见了。可是，Pete怎么出去呢？好在Pete又遇到了a jellyfish、an angelfish，借助他们的光亮，游出了黑洞。 出来之后，怎么还是那么黑呢？故事又开始紧张了。原来，是一只whale。最后，Pete坐上了一只sea turtle，回到了船上。且在上船之前终于发现了一直尾随着他的小海马。What a surprised journey！整个英文的句式存在一定的重复性，而且名词前关于“a”与“an”的反复应用，也可以让孩子对于英语的学习有一定的感知。 总结：无论是英文绘本，还是中文绘本，抛开家长引导的工作好坏以及表达水平，故事是否有趣是决定性的。猫、海底生物、潜水，这些元素，正好抓住了我家孩子的痛点，也为我选择绘本提供了一个方向。

General relativity predicts a particularly dense dark objects. Evolution of massive stars in their late collapse occurs, the dense material in particular, it has one called "event horizon" of the closed border, a black hole hidden in a huge gravitational field, due to the gravitational field so strong, including in particular photon (ie the composition of light particles, the speed c = 3.0 × 10 ^ 8m / s), including any material can only be entered could not escape. The formation of a black hole minimum mass star's core is about three times the solar mass, of course, this is the last star of nuclear quality, rather than main sequence stars in the period of quality. In addition to this stellar-class black hole, there are other sources of black holes - the so-called micro-black holes may be formed in the early universe, the so-called supermassive black holes may exist in the central galaxy. A black hole can be found through the concept of electronic equipment. The black hole within its borders to prevent any outsiders to see anything, which is the object known as the "black hole" of the reason. We were unable to observe the reflection of light it can only be affected indirectly understand the objects around the black hole. Having said that, but the black hole still has its borders, namely "event horizon (horizon)." It is assumed that the evolution of stellar black hole of death matter, is in a special super-massive stars collapse generated. In addition, the quality of a black hole must be larger than the Chandrasekhar limit of stellar evolution to the end of the form, quality, smaller than the Chandrasekhar limit of the star is unable to form a black hole. 翻译成汉语就是下面的意思----广义相对论预言的一种特别致密的暗天体。大质量恒星在其演化末期发生塌缩，其物质特别致密，它有一个称为“视界”的封闭边界，黑洞中隐匿着巨大的引力场，因引力场特别强以至于包括光子(即组成光的微粒，速度c=3.0×10^8m/s)在内的任何物质只能进去而无法逃脱。形成黑洞的星核质量下限约3倍太阳质量，当然，这是最后的星核质量，而不是恒星在主序时期的质量。除了这种恒星级黑洞，也有其他来源的黑洞——所谓微型黑洞可能形成于宇宙早期，而所谓超大质量黑洞可能存在于星系中央。黑洞可以经由电子仪器观查到。 黑洞不让任何其边界以内的任何事物被外界看见，这就是这种物体被称为“黑洞”的缘故。我们无法通过光的反射来观察它，只能通过受其影响的周围物体来间接了解黑洞。虽然这么说，但黑洞还是有它的边界，即“事件视界（视界）”。据猜测，黑洞是死亡恒星的演化物，是在特殊的大质量超巨星坍缩时产生的。另外，黑洞必须是一颗质量大于钱德拉塞卡极限的恒星演化到末期而形成的，质量小于钱德拉塞卡极限的恒星是无法形成黑洞的。【希望这个可以帮助您】
