大自然中的奇迹
大自然中蕴藏着许多奇迹，其中一个最引人注目的是彩虹。彩虹是一道美丽的自然现象，它在空中展现出七种不同颜色的光芒，给人们带来了无尽的惊喜和喜悦。那么，彩虹是如何形成的呢？答案就隐藏在定语从句中的which引导的句子中。
彩虹的形成与自然光的折射和反射有关。当阳光穿过空气中的小水滴时，它们会发生折射，也就是光线改变传播方向。这意味着，阳光的光谱会分离成七种不同的颜色。这些颜色包括红、橙、黄、绿、蓝、靛、紫。每一种颜色都有不同的波长和频率，所以它们会以不同的角度折射和反射。这样，当阳光经过水滴后，会形成一个圆弧形的光谱，也就是我们所看到的彩虹。
在天气晴朗的日子里，我们可以看到彩虹出现在雨后的天空中。这是因为雨滴充当了光的折射介质，使得阳光能够被分解成七种颜色。而且，彩虹的形成还受到太阳、观察者和水滴之间的相对位置的影响。只有当太阳的光线以一定的角度射入水滴，并经过折射和反射后，才能形成彩虹。观察者必须位于太阳和彩虹之间的适当位置，这样才能看到完整的彩虹。
彩虹的美丽和神秘感吸引了许多人的注意。它是大自然中的一道奇迹，也是对光的折射和反射现象的生动展示。每次看到彩虹，人们都会感到一种宁静和喜悦。它提醒我们珍惜大自然的美丽，也让我们对科学的奇妙之处产生了更深的思考。

探索未知的宇宙
宇宙是一个无边无际的宏伟空间，蕴藏着无数的奥秘和未知。人类一直对宇宙充满好奇和探索的欲望。然而，我们对宇宙的认识还只是冰山一角。在这个宏伟的宇宙中，有一个神秘的黑洞引起了科学家们的极大兴趣。那么，黑洞是什么？它又是如何形成的呢？答案可以在定语从句中的which引导的句子中找到。
黑洞是宇宙中一种极为奇特的天体，它具有极强的引力，甚至连光也无法逃脱。黑洞的形成与恒星的演化过程有关。当一颗恒星燃尽了它的燃料，它会发生剧烈的爆炸，形成一个巨大的恒星残骸。如果这个残骸的质量足够大，它的引力会将自身压缩到极限，形成一个黑洞。
黑洞的引力极强大，它可以吞噬附近的物质，甚至连光也无法逃脱。这使得黑洞成为一个真正的宇宙奇观。然而，科学家们对黑洞的研究还远远不够。我们对黑洞的内部结构和性质知之甚少。目前，科学家们正在努力寻找黑洞的证据，并希望能够进一步揭示黑洞的奥秘。
黑洞的存在引发了许多哲学和科学上的思考。它让我们对宇宙的起源和未来产生了更多的疑问。我们是否能够利用黑洞的能量？黑洞是否能够成为人类探索宇宙的桥梁？这些问题都需要我们深入研究和探索。黑洞是宇宙中的一个谜题，也是人类对未知的渴望和勇气的象征。
无论是彩虹还是黑洞，它们都是大自然中的奇迹，代表着人类对未知的探索和好奇心。通过定语从句中的which引导的句子，我们可以更深入地了解这些奇迹的形成原理和背后的科学原理。这些奇迹不仅让我们对大自然充满敬畏，也让我们对科学的力量产生更大的信心和兴趣。让我们继续探索未知的宇宙，发现更多的奇迹！

which引导的定语从句的用法
如： He was reading a book, which was about war. 他正在读一本关于战争的书。(关系代词which在修饰book的定语从句中充当主语。)
He was reading a book, which he had bought from London. 他正在读一本书， 这本书是从伦敦买回来的。(关系代词which在修饰book的定语从句中充当宾语。)
which引导非限定性定语从句时有一个特殊用法， 即它所引导的非限定性定语从句修饰主句中更多的部分甚至整个主句(这时被定语从句所修饰的“先行词”要作广义理解)， which仍在定语从句中作主语、 宾语或表语。例如：
He set free the birds happily， which was a celebration for his success. 他开心地把鸟放了， 这是对他成功的一种庆祝。
把非限定性定语从句“which was a celebration for his success”的先行词视为主句中的“the birds”显然不符合整句的语境， 被“which was a celebration for his success”所修饰的是整个主句， which所引导的这类特殊的非限定性定语从句对主句所叙述的情况进行某种意义的补充说明， which常可译为“这一点， 这件事”。
