英语翻译
If a free carbon atom were to form 2 covalent bonds with two free hydrogen atoms it has been calculated that about 1028KJ/mol of energy would be released.To promote a 2s electron in carbon to a 2p orbitals(excitation energy )and then to hybridise the 4 orbitals to give 4 sp3 hybrid orbitals (hybridisation energy)takes 405KJ/mol.This energy though is more than compensated for by the energy released on forming 4 covalent bonds,2057KJ/mol.Thus carbon forms compounds in which the carbon forms four rather than two bonds.
这段话是说405KJ/mol是被2057KJ/mol补偿了么,可是1028KJ/mol也比405大哇.

大概看了一下,把意思告诉你,没有逐字翻译
如果一个自由C原子想要和两个自由H原子成共价键,需要1028KJ/mol的能量.激发一个C原子中2S轨道的电子到2P轨道得到4个SP3杂化轨道需要405KJ/mol的能量.这个能量小于形成4个共价键所需要的2057KJ/mol.所以C成结合4个原子而不是成两个共价键

这个应该是讲的一个C原子和2个H原子形成2个共价键会释放1028KJ/mol 的能量（4个共价键释放2056KJ/mol 下文的2017），将2个S轨道的电子激发到2P轨道上，然后4个轨道杂化成4个能量相同的sp3轨道，将会消耗 405KJ/mol的能量，这些消耗的能量完全可由形成4个共价键释放的,2057KJ/mol的能量来提供（compensated 补偿）。
大意是形成sp...

大意是形成sp3杂化轨道使能量降低。。。。

直接拿一本大学的有机化学看嘛这个是英国高中课本。。。。。T T哎，这个知识我们大学才教啊，原来你在考雅思不是。。。。谁学雅思还翻译啊。。。。这个就是课本。。。我只是对这个有的东西不是很明白，觉得翻译一下可能好一点就是说本来两个共价键就有 1028KJ/mol 生成，如果电子激活下，轨道杂化可以生成4个SP3轨道，虽然这个过程需要405KJ/mol的能量，但是这4个单电子与氢自由基形成四个共价键的话...
