解释: 本句容易读错。有的人把that引导的宾语从句中的left over from the “big bang” when the galaxies were formed看成了一个整个的部分,都是修饰前面的gases的,这样就把从句的主干看成了this intergalactic gas is a mixture of A and B ,句子的意思也就理解成“星际间的气体是由A与B形成的混合物”,其实是错误的,因为A在句中是gases,而B则是gas was forced out of...,是一句话,这两者是不可以并列的。另外,这种理解在意思上也说不通:大爆炸肯定应该是早于星系的形成的。

惟一正确的理解是,mixture就是gases的mixture;而后面的when 所引导的时间状语从句是修饰整个宾语从句的,说明混合物形成时的宇宙状态。when 从句中的and是连接两个并列的说明星系情况的句子的。这种在when前后的部分都很长的C when D的结构,与其把它理解为“当D的时候,发生了C”,在阅读的现场倒不如理解成“C发生了,当时D在发生”来得更清楚、更舒服。
